A CABINET FIELD OF THE INVENTION The present invention relates to the field of refrigerating electronicequipment. ln particular, the invention relates to a cabinet for the refrigerationof electronic equipment positioned therein.
BACKGROUND OF THE INVENTION For the housing of electronic equipment such as e.g. batteries, servers,processors, measuring equipment, telecommunication equipment and opticalfibers, cabinets are well known. The benefits of these enclosures arenumerous, not only considering an improved order of the equipment, but alsodue to aspects regarding safety such as protection from theft, fire, leakageand so on. Cabinets are moreover used for shielding or isolating theelectronic equipment from external environments having a deteriorating effectthereon. Also, the cabinets may be arranged to cool the electronic equipment.The cabinets may be adapted for an external, outdoor use, where they aretypically constructed to be weatherproof so as to minimize the risk ofequipment damage.
The improvements in design and construction of electronics,telecommunications and batteries have lead to a development strivingtowards smaller equipment with an increased power. For batteries, it is knownto those skilled in the art that high temperatures within the enclosure tend todecrease the service life of the batteries, necessitating costly servicing and/orbattery replacements. ln other words, a battery operating in a high- temperature environment may have its lifetime shortened.
One example of an outdoor cabinet to be used in a telecommunicationsystem is disclosed in patent document SE 518304. A climate controllingdevice is provided in the door and fans are arranged above each of theelectronic units situated in the interior of the cabinet, wherein each of the fans 2removes and forwards heat generated by the units to an internal channel system. The heated air is transported to a heat exchanger which absorbs andforwards the heat via an external flow of air to the ambient air outside thecabinet. Additional fans blow the cooled air into a space between the doorand the cabinet body in front of the electrical equipment.
Another example of a prior art cabinet for controlling the environmentalconditions within a telecommunications base station is disclosed in patentdocument GB 2277767. The temperature of the air within the base station iscontrolled by apparatus incorporated in or on a door. ln use, fans drawexternal air into the interior of the base station through a louvered panel. Theexternal air passes across the heat exchanger, and the internal air from withinthe base station is also drawn across the heat exchanger, the air leaving thebase station through a second panel.
However, there are problems related to the aforementioned structures.The arrangements disclosed do not provide a controlled and evenlydistributed cooling or refrigeration throughout the interior of the cabinet.
SUMMARY OF THE INVENTION lt is an object of the present invention to mitigate the above problemsand to provide a cabinet that provides an improved climate control of theelectronic equipment contained therein.
This and other objects are achieved by providing a cabinet having thefeatures defined in the independent claim. Preferred embodiments aredefined in the dependent claims.
According to a first aspect of the present invention, there is provided acabinet for refrigerating electronic equipment positioned in acompartment of a cabinet body. The cabinet is further arranged with a cabinetdoor for closing an access opening to said compartment. When the cabinetdoor is closed, the cabinet body together with the closed cabinet door encloses the compartment. lt is understood that the refrigerating effect can 3only be achieved when the Cabinet door is closed. Also, opening the cabinet door will uncover the access opening, whereby electronic equipment may bepositioned therein or, if the electronic equipment is already positioned therein,the electronic equipment or a part thereof may be removed and/or replacedwith other electronic equipment.
The term “electronic equipment” should, in this context, be construed ase.g. batteries, servers, processors, measuring equipment, telecommunicationequipment, optical fibers or the like. Moreover, the electronic equipment forwhich the cabinets are provided have different specific operationaltemperature intervals, e.g. 0-45 O C. ln other words, the electronic equipmentis intended to operate within a specific operational temperature intervalsuitable for the function thereof. Also, in addition to the refrigeration of theelectronic equipment, some electronic equipment generate heat which needsto be compensated for.
Also, the cabinet is further arranged with at least one partitioning meansfor partitioning the compartment into at least two sub-compartments. Thus,the space of the compartment is partitioned into at least two smallercompartment spaces, i.e. two sub-compartments. The at least two sub-compartments are in fluid communication, i.e. the partitioning means providean opening or openings between the sub-compartments. ln other words, thepartitioning means are arranged such that the sub-compartments are in fluidcommunication. lt should noted that the term “partitioning means” as used herein isintended to refer to at least a partition or wall or the like which separates ordivides the compartment into sub-compartments. Thus, partitioning meansmay for example be shelves, racks, plates, boards or the like.
Moreover, the cabinet is further arranged with a cooling system, whereinthe cooling system is arranged in the cabinet door. The cooling system is influid communication with the compartment via a fluid outlet and a fluid inlet.Thus, the fluid inlet and the fluid outlet are in fluid communication with the atleast two sub-compartments. The cooling system comprises a fan fordischarging cooling fluid via the fluid outlet into at least a first sub- compartment of the at least two sub-compartments. Also, the fan exhausts 4fluid via at least a second sub-compartment of the at least two sub- compartments through the fluid inlet. Thus, the at least one first sub-compartment is a sub-compartment into which cooling fluid is discharged,whereas the at least one second sub-compartment is a sub-compartmentthrough which the cooling fluid is exhausted. The fan simultaneously causesboth a discharging effect and an exhausting effect, thereby contributing togenerate a flow inside the compartment. During operation the fan dischargescooling fluid, i.e. exhausted fluid which has been cooled by the coolingsystem, into and through the at least one first sub-compartment. Thereafter,the cooling fluid continues until it reaches the at least one second sub-compartment and thereafter continues via the fluid inlet back to the coolingsystem which again cools the exhausted fluid for further discharge. lt isunderstood that if the electronic equipment generates heat, the coolingsystem is arranged to compensate for this additional heat, thereby providingan optimal operation temperature for the electronic equipment.lt should be noted that the term ”discharging cooling fluid” as used herein is intended to refer to a delivery of a cooling fluid into a constrainedspace, thereby generating a flow in the space. Analogously, the term”exhausting fluid” as used herein is intended to refer to an emptying of aconstrained space. ln other words, fluid is drawn from a space therebygenerating a low pressure or under-pressure in that space.
Also, the cabinet is further arranged with at least one gasket for abutting,upon closing the cabinet door, the at least one partitioning means to saidcabinet door. Furthermore, the at least one gasket abuts the at least onepartitioning means which partitions the at least one first sub-compartment andthe at least one second sub-compartment to said cabinet door. Thus, at leastthat or those partitioning means which partitions the at least one second sub-compartment from the at least one first sub-compartment, abuts or abut thecabinet door by means of the at least one gasket, upon closing the cabinetdoor. When the cabinet door is closed, the at least one gasket is in anabutting position with both the cabinet door and the partitioning meansthereby hindering, at the cabinet door, fluid to pass between the at least first and second sub-compartments. Thus, when the cabinet door is closed, the at 5least one partitioning means and the at least one gasket provide a fluid hindering effect at least along that or those partitioning means providedbetween the at least one first sub-compartment and the at least one secondsub-compartment, where the partitioning means faces the closed cabinetdoor. ln other words, fluid is hindered to enter the at least one second sub-compartment from adjacent sub-compartments at the region where thepartitioning means faces the closed cabinet door. ln the case where the cabinet is arranged with two or more partitioningmeans, i.e. the compartment is partitioned into three or more sub-compartments, gaskets may be arranged for abutting each of the partitioningmeans to said cabinet door when closed. lt is also understood that gasketsmay be arbitrarily arranged as long as the gasket or gaskets at least abuts thepartitioning means of the at least one second sub-compartment to the closedcabinet door.
The term “gasket” should, in this context, be construed as an element formaking a joint fluid-tight or at least hinder fluid to pass the joint. Thus, hereinthe gasket is used for making the joint between the door and the partitioningmeans. The gasket is preferably an elastomeric strip, border, edging or thelike.
Thus, the present invention is based on the idea of using at least onegasket in combination with at least one partitioning means which partitions thecompartment into sub-compartments which are in fluid communication. Theuse of the gasket in combination with said partitioning means makes itpossible to control a distribution of refrigerating fluid throughout saidcompartment in an advantageously accurate and reliable manner. Thereby,the discharge of the cooling fluid from the cooling system will be supplied tothe compartment of the cabinet with a minimized leakage to at least thesecond sub-compartment or sub-compartments at the cabinet door whenclosed. This minimization of leakage will ensure that the at least one first sub-compartment into which cooling fluid is discharged will be supplied with aproper amount of cooling fluid whereby an accurate and reliable refrigerationof each sub-compartment is achieved. Also, since the at least one second sub-compartment, via which fluid is exhausted from, is partitioned from the at 6least one first sub-compartment, via which cooling fluid is discharged, any unwanted “short-circuiting” flow from the fluid outlet directly to the fluid inlet atthe cabinet door is reduced.
According to an embodiment of the invention, the at least two sub-compartments may be vertically displaced, i.e. provided on top of each otherwithin the cabinet. ln this embodiment, the at least one partitioning means forpartitioning the compartment into at least two sub-compartments are arrangedhorizontally. lt is understood that the number of sub-compartments may bevaried dependent on the size of the electronic equipment to be positionedtherein. The size of the sub-compartment is adapted to the size of theelectronic equipment unit to be positioned therein. lt is also understood thatthe sub-compartments within the same cabinet may be of different sizes.
Alternatively, the at least two sub-compartments may be horizontallydisplaced, i.e. provided side-by-side within the cabinet. ln this embodiment,the at least one partitioning means for partitioning the compartment into atleast two sub-compartments may be arranged vertically.
Alternatively, any combination of vertical and horizontal displacement ofthe at least two sub-compartments within the cabinet is also feasible. As anexample, at least two sub-compartments may be horizontally displaced, i.e.provided side-by-side within an upper portion of the cabinet whereas in alower portion of the cabinet, at least two sub-compartments may be verticallydisplaced, i.e. provided on top of each other. lt is also understood that the fluid outlet and fluid inlet are displaced inanalogy to the displacement of the sub-compartments, e.g. that a cabinethaving vertically displaced sub-compartments is provided with verticallydisplaced fluid outlets.
Analogously, in an embodiment where the at least two sub-compartmentsare horizontally displaced, the fluid outlet openings may be horizontallydisplaced such that the relative positions between the fluid outlet openingsarranged in the cabinet door at positions facing a first of at least two sub-compartments and the at least one first sub-compartment is substantiallyidentical to the relative positions between the fluid outlet openings arranged in 7the Cabinet door at positions facing a second of at least two sub- compartments and the at least one second sub-compartment.
According to an embodiment, the fluid out|et comprises a plurality offluidout|et openings which are arranged in the cabinet door at positions facing theat least one first sub-compartment. By the plurality of fluid out|et openings, thedischarge of cooling fluid via the fluid out|et into the first sub-compartment isimproved. One aspect of the improvement is that the cooling fluid may bedischarged first after the fluid has passed within the cabinet door to theopenings facing the at least one first sub-compartment.
Another aspect of the improvement is that a plurality of fluid out|etopenings divides the discharge into a plurality of small discharge flows whichspread the discharge into the at least one first sub-compartment. The sizeand the formation of the fluid out|et openings may be formed and/or arrangedto achieve a predetermined spread and velocity of the discharged coolingfluid. The realization of the fluid out|et openings in the cabinet door may beholes, louvers, grilles, gratings or the like. ln an embodiment, the plurality offluid out|et openings is arranged suchthat the cooling fluid is evenly distributed into the at least one first sub-compartment. The plurality offluid out|et openings may be equally spacedapart in the cabinet door within an area facing the at least one first sub-compartment when the door is closed. ln other words, the plurality offluidout|et openings may be symmetrically placed facing the at least one first sub-compartment when the cabinet door is closed. Alternatively, the plurality offluid out|et openings may be arranged such that they face an intermediatespace, i.e. the space between the partitioning means and the electronicequipment, of the sub-compartment which is not occupied by electronicequipment, thereby ensuring that the discharged cooling fluid may easilyenter and penetrate the at least one first sub-compartment. One benefit of anevenly distributed cooling fluid is to provide a uniform cooling of the sub-compartment. More specifically, the distribution may provide a homogeneouscooling temperature in the at least one sub-compartment, avoiding divergingtemperature conditions within the sub-compartment. Another benefit of an evenly distributed cooling fluid is the enhanced possibility of an evenly 8distributed flow through the sub-compartments, thereby avoiding fluid convection which may worsen the cooling performance of the cabinet.
Moreover, the plurality offluid outlet openings may be arranged such thatthe cooling fluid is individually distributed into the at least one first sub-compartment. This is advantageous when different electronic equipment orequipment with different sizes are positioned within different sub-compartments of the cabinet body, such that the cooling fluid may bedischarged individually into the sub-compartments. As an example, a coolingfluid may be discharged through small holes in one of the at least one firstsub-compartment, thereby creating a higher fluid velocity which may forexample be in adaptation for the electronic equipment provided in that sub-compartment. ln another of the at least one first sub-compartment, a coolingfluid may be discharged through big holes, thereby creating a lower fluidvelocity, which may for example be in adaptation for the electronic equipmentprovided in that sub-compartment. ln an embodiment, the fluid inlet comprises at least one fluid inlet openingarranged in the cabinet door at a position facing the at least one second sub-compartment. This embodiment further enhances the exhausting effect at thefluid inlet.
According to an embodiment, the total area of the plurality of fluid outletopenings is less than that of the at least one fluid inlet opening. This willincrease the fluid velocity from the outlet openings into the sub-compartments. ln an embodiment, the at least one first sub-compartment is arranged atone end of the compartment and the at least one second sub-compartmentarranged at an opposite end, thereby allowing fluid to flow from one end ofthe compartment to the opposite end thereof. By this arrangement, thedistribution of cooling fluid throughout the compartment is thereby enhancedeven further. The fluid inlet and fluid outlet are thus also arranged at oppositeends of the door.
According to an embodiment, the at least one partitioning means providesa hermitical partitioning at least at the end of the at least one partitioning means facing the cabinet door. Thus, at least that portion of the at least one 9partitioning means which is adjacent to the closed Cabinet door provides an hermetical partitioning between the thereof partitioned sub-compartments.The hermetical partitioning hinders any fluid communication to pass betweentwo adjacent sub-compartments at the cabinet door. By this, any Ieakagebetween the sub-compartments at the door is reduced even further, therebyenhancing the cooling and refrigeration performance of the cabinet.ln an embodiment, the sub-compartments are in fluid communicationalong a rear side of the compartment opposite the access opening. Thismeans that each flow from all sub-compartments are reassembled along arear side, thereby collecting the individual flows from each and every sub-compartment before entering a final sub-compartment which forwards thecollected or gathered flow from the rear side of the compartment and throughthe inlet into the cooling system at a front side. This rear side fluidcommunication ensures that the cooling flow passes the compartment fromthe front side, i.e. the side where the door encloses the access opening, tothe backside, thereby enhancing the distribution of cooling fluid throughoutthe compartment even further.ln an embodiment, the at least one gasket may be attached to the at leastone partitioning means for abutting the cabinet door upon closure thereof.This is advantageous in the cases cabinet doors need to be replaced, as thereplacing cabinet doors may not have to be provided with any gasket.Alternatively, the at least one gasket may be attached to the cabinet doorfor abutting the at least one partitioning means upon closure of the cabinetdoor. This arrangement may be preferred when loading or unloading thecabinet with electronic equipment, as the attachment of the gasket to the doorinstead of on the partitioning means may provide an easier access to theopening of the cabinet.ln yet another embodiment, the at least one gasket comprises at least a first gasket element attached to the cabinet door and a second gasketelement attached to the at least one partitioning means, wherein the firstgasket element and the second gasket element are arranged to co-operatewith each other upon closure of the cabinet door. Thus, when the door is closed, the first gasket element and the second gasket element are in a fluid- tight contact with each other.
According to an embodiment, the cabinet is arranged with partitioningmeans for partitioning the compartment into a plurality of sub-compartmentsbeing in fluid communication, and wherein the fan exhausts fluid via one sub-compartment and discharges cooling fluid into all other of said plurality of sub-compartment. Thus, the fan of the cooling system discharges cooling fluid viathe fluid outlet into all of sub-compartments except one sub-compartment,which fluid is exhausted via. ln other words, fluid is exhausted via one sub-compartment and cooling fluid is discharged into all of the other sub-compartments of the plurality of sub-compartments. This further enhances thedistribution of refrigerating fluid to all parts of the compartment duringoperation. ln an embodiment, the cabinet is arranged with at least two compartmentswhich are isolated from each other upon closure of the cabinet door.According to this embodiment, the at least two compartments may be haveclimates substantially independent of each other. This may have the furtheradvantage that different electronic equipment having different operationaltemperature intervals may be positioned in separated compartments, therebyproviding the possibility of a more selected climate control, e.g. by providing afirst temperature within a first compartment and a second temperature in asecond compartment, the first and the second temperatures being different.

Referring to Fig. 1, a cabinet 1 for refrigerating electronic equipment isshown. The cabinet 1 comprises a cabinet body 2, defined by a top portion, abottom portion, a back portion and two side portions, which together form avertically elongated rectangular para|e|epiped. The isolation of the cabinetbody 2 is adapted for an external, outdoor use, as the cabinet body 2 istypically constructed to be weatherproof so as to minimize the risk of damageof the electronic equipment positioned therein. The cabinet body 2 encloses acompartment 3, wherein the electronic equipment is positioned.
A cabinet door 4 for closing or opening an access opening 5 is verticallyhinged on a vertically elongated edge 6 between a side portion and theaccess opening 5 of the cabinet body 2. The cabinet door 4 which opens in aclockwise direction and closes in a counter-clockwise direction, is shown inFig. 1 in an open position. Arranged in the cabinet door 4 is a cooling system7 (not illustrated) in fluid communication with the compartment 3. The coolingsystem 7 is provided behind a plate 31 in the cabinet door 4, through whichplate 31 the fluid communication is realized by a fluid outlet 8. The fluid outlet8 is arranged as circular holes, the holes providing a fluid communicationbetween the cooling system 7 and the compartment 3. The circular holes aredistributed horizontally in three rows with holes arranged in an upper row 8a,a center row 8b and a lower row 8c. The rows are separated vertically,wherein the upper row 8a is provided at the top of the cabinet door 4, thelower row 8c is provided in the approximate center of the cabinet door 4, andthe center row 8b is provided approximately between the upper row 8a andthe lower row 8c. A fluid inlet 9 is arranged at the base of the cabinet door 4,the fluid inlet 9 providing a fluid communication between the cooling system 7and the compartment 3. The fluid inlet 9 is an opening defined by the plate 31and an interior surface (not indicated) of the door 4. The inlet is substantially 12rectangular and elongates horizontally along the width of the door. The base of the rectangle is horizontal, whereas the top of the rectangle is triangular-shaped, yielding a slimmer waist at the center of the rectangle to form anhourglass shape. The triangular shape of the plate 31 concentrates thepossible formation of condensed fluid from the cooling system 7 such that adrainage of the condensed fluid is facilitated.
A plurality of batteries 30 is arranged in the compartment 3 in fourvertically separated sub-compartments, each sub-compartment beingprovided with horizontally arranged batteries. The sub-compartments arearranged as an upper sub-compartment 10a, an upper center sub-compartment 10b, a lower center sub-compartment 10c and a lower sub-compartment 10d. The upper sub-compartment 10a is provided at the top ofthe compartment 3, wherein the upper center sub-compartment 10b isprovided between the approximate center of the compartment 3 and theupper sub-compartment 10a, the lower center sub-compartment 10c isprovided between the approximate center of the compartment 3 and the lowersub-compartment 10d, and the lower sub-compartment 10d is provided at thebase of the compartment 3.
A horizontally mounted gasket 11 is provided on the interior of the cabinetdoor 4 such that upon closing the cabinet door 4, the gasket 11 abutshorizontally the mounted partitioning means 12, thereby hindering a fluid topass the partitioning means 12 at the cabinet door 4.
Fig. 2 shows a side cross-sectional view of the cabinet 1 wherein thecabinet door 4 of the cabinet body 2 is closed, thereby providing a hermeticalenclosure of the interior of the cabinet 1 from the outside ambience. Withinthe cabinet 1 the fluid passes a circulating fluid path 13. ln the cabinet door 4,the path 13 elongates vertically from the base of the cabinet door 4 to the topof the door 4. From the cabinet door 4, the path is divided from the threevertically separated sets offluid outlet openings 8a, 8b, 8c between thecooling system 7 and the compartment 3. The circulating fluid path 13extends from the outlet 8 into the three upper sub-compartments 10a, 10b,10c arranged in the compartment 3. The sub-compartments 10a, 10b, 10c, 10d are separated vertically by the partitioning means 12, the sub- 13compartments 10a, 10b, 10c, 10d and the partitioning means 12 extending horizontally from the fluid outlet 8 to a vertically elongated rear space portion14, adjacent to the back portion 15 of the cabinet body 2. The partitioningmeans comprise hereby shelves. The three sub-compartments 10a, 10b, 10cprovide a divided fluid path 13, passing from the fluid outlet 8 to the rearspace portion 14. The divided fluid path 13, substantially parallel to an axisbetween a sub-compartment in|et and a sub-compartment outlet, isreassembled at the rear space portion 14, wherein the circulating fluid path 13is directed downwards. The fourth sub-compartment 10d, provided at thebase of the cabinet 1, directs the fluid path 13 from the rear space portion 14towards the fluid in|et 9.
The coo|ing system is provided with a heat exchanging device 16 (notshown) which is arranged in the cabinet door 4. The heat exchanging device16 is arranged in the door for exchanging heat from the compartment to avertically elongated duct 17 provided along an outer portion of the cabinetdoor 4. The duct 17 elongates parallel to the part of the circulating fluid path13 within the cabinet door 4, the duct 17 and the path 13 being separated. Aduct in|et 18 is provided at the base of the cabinet door 4, providing a fluidcommunication between the outside ambience and the base of the duct 17. Aduct outlet 19 is provided at the top of the cabinet door 4, providing a fluidcommunication between the top of the duct 17 and the outside ambience. Acompressor 20 is provided in the cabinet door 4 at the base of the duct in|et18.
The part of the circulating fluid path 13 within the cabinet door 4 passesthe heat exchanging device 16 which cools the fluid from the in|et 9. A fan 23is provided which sucks the coo|ing fluid from below and b|ows the fluidupwards, such that the coo|ing fluid is discharged through the fluid outletopenings 8a, 8b and 8c, provided above the fan 23. Thus, the fluid isdistributed along the circulating fluid path 13 from the apertures 8a, 8b, 8cbetween the coo|ing system 7 and the compartment 3. The fluid passesthrough the sub-compartments 10a, 10b and 10c to the rear space portion 14,and is reassembled at the rear space portion 14, wherein the fluid is directed downwards. From the base of the rear space portion 14 towards the fluid in|et 149, the fluid passes through the fourth sub-compartment 10d and via the fluid inlet opening 9. ln Fig. 3, a Cabinet 1 is shown in a perspective view with the cabinet door4 open. The cabinet body 2, shaped as a rectangular parallelepiped, has aninterior which is divided by a horizontally mounted shelf 24 into a lowercompartment 3 and an additional upper compartment 40 provided above thecompartment 3. The shelf 24 is provided approximately in the middle of thecabinet body 2. ln the compartment 3, batteries 25 are arranged in twovertically separated sub-compartments 25a and 25b, each sub-compartmentbeing provided with 4 batteries arranged along a horizontal axis. The sub-compartments 25a, 25b are partitioned by a horizontally elongated shelf 26.
A cooling system 7 is provided within the lower part of the cabinet door 4,the system being in fluid communication with the compartment 3 when thecabinet door 4 is closed. The communication is realized by a fluid outlet 8 anda fluid inlet 9, wherein the fluid outlet 8 is arranged as circular holes in theplate 31, the holes providing a fluid communication between the coolingsystem 7 and the lower compartment 3. The holes are distributed horizontallyin a row at the approximate center of the cabinet door 4. The inlet 9 isarranged at the base of the cabinet door 4, the inlet 9 providing a fluidcommunication between the cooling system 7 and the compartment 3 whenthe cabinet door is closed. ln the upper part of the cabinet body 2, theadditional upper compartment 40 is provided with another type of electronicequipment 27. The upper and the lower compartments 3a, 3b are separatedby the shelf 24, thereby providing two independently systems. For example,the compartment 3 provides a refrigerating compartment whereas theadditional upper compartment 40 is a non-refrigerating compartmenthermetically sealed, when the door is closed, from the lower compartment 3.
Shown in a perspective view in Fig. 4 is a cabinet wherein twocompartments 3a, 3b are provided side-by-side in the cabinet body 2. Avertically arranged wall 28 in the center of the cabinet separates the twocompartments 3a, 3b.
Two cabinet doors 4a, 4b are vertically hinged on the cabinet body 2 at opposite sides of the access openings 5a and 5b, respectively. The leftmost door 4a opens in a clockwise direction, and closes in a counter-clockwise direction. Analogously, the rightmost door 4b opens in a counter-clockwisedirection, and closes in a clockwise direction. The two doors 4a, 4b close atthe vertical wall portion 28. The two doors 4a, 4b in Fig. 4 are both shown inan open position. Provided within each cabinet door 4a, 4b is a coolingsystem such that the cabinet provides two cooling systems 7a, 7b. By this,two compartments 3a, 3b with individual refrigerating operations may beprovided, adapted to provide an improved cabinet refrigeration.
Even though the invention has been described with reference to specificexemplifying embodiments thereof, many different alterations, modificationsand the like will become apparent for those skilled in the art. The describedembodiments are therefore not intended to limit the scope of the invention, asdefined by the appended claims. For example, the shape of the fluid inlet 9and the fluid outlet 8 may take on any other geometrical shapes than thosedepicted. Louvers, grilles, gratings or the like are all possible embodiments ofthe fluid inlet 9 and fluid outlet 8. Moreover, the rectangular parallelepipedshape of the cabinet body 2 may instead be of e.g. cubic or cylindric shape.Furthermore, the door 4 may be opened clockwise or anti-clockwise, upwardsor downwards, dependent on how the door is hinged to the cabinet body 2.Alternatively, the door may instead be replaced by a closing means forclosing the access opening 5, the closing means being provided withfastening means such as screws, locking means or the like.
Further, any number and placement of sub-compartments within a cabinetbody 2 may be feasible. As an example, a cabinet body 2 may have thestructure of the body depicted in Fig. 4 with two compartments 3a, 3b side-by-side, but wherein one or both of the compartments may be divided asdepicted in Fig. 3 with a horizontally mounted shelf 24.
The fan 23 in Fig. 2, may alternatively be substituted by a turbine,pump, or the like, to generate a flow of the fluid within the cabinet door 4.Moreover, instead of a cabinet body 2 with the shape of a verticallyelongated rectangular parallelepiped, the parallelepiped may be elongatedhorizontally. ln this embodiment, the fluid outlet 8 may instead of beingprovided as rows be provided as columns, and, consequently, instead of 16 being separated vertically be separated horizontally. ln combination, orindependently of this embodiment, the vertically hinged door 4 may insteadbe hinged horizontally on a horizontally elongated edge between the topportion and the access opening 5 of the cabinet body 2.
Furthermore, the gasket 11 as disc|osed in Fig. 1 may not only beprovided in the cabinet door 4 but also on the partitioning means 12 at theaccess opening 5 such that a first gasket element provided on the door 4 anda second gasket element provided on the partitioning means 12 abut uponclosing the door 4 such that a fluid is hindered to pass the partitioning means12.
Moreover, any other heat exchanger 16 than in the embodiment disc|osed inFig. 2 may be feasible. As an alternative, parts of the disc|osed heatexchanger elements or additional auxiliary elements may be provided outsidethe cabinet body 2.
