    [001] The invention relates to a refrigeration arrangement for components arranged in the internal space of a switch cabinet having a switch cabinet and a refrigeration apparatus, which has a first closed cooling medium circuit and a second circuit of the cooling medium separated by fluid from it, whereby the first circuit of the cooling medium has a refrigeration device or a cold water unit, and the second circuit of the cooling medium has an arrangement of heat pipes or a two-way thermosyphon phases. Such a refrigeration arrangement is known from patent document DE 102 96 928 T5. Patent documents DE 690 05 701 T2, US 2003/0057546 A1 and US 2012/0103571 A1 likewise respectively describe a similar arrangement.
    [002] Refrigeration appliances of this type often comprise a refrigeration machine, in which a compressor, a condenser, an expansion means are arranged in a circuit of the refrigeration medium one after the other in the direction of flow of the refrigeration medium. and an evaporator. In principle, the refrigeration machine is designed to ensure sufficient cooling of the internal space of the control cabinet under extreme conditions, ie in the case of maximum ambient temperatures and at the same time maximum dissipation of the components received in the switch cabinet. Since these extreme conditions, however, only exist in exceptional cases, most of the time, the refrigeration machine is in on-off operation, that is, in an energetically inefficient operating mode.
    [003] Furthermore, refrigeration machines have the disadvantage of presenting a relatively high energy consumption. Therefore, in principle, it is desirable at least proportionally to prepare the necessary refrigeration capacity with the aid of alternative refrigeration techniques. For this purpose, from the prior art, refrigeration apparatuses are known, which combine an air and water heat exchanger with a refrigerating machine, in such a way that in case of a sufficiently large temperature difference between the theoretical temperature of the cabinet temperature of the distribution cabinet and the ambient air temperature of the switch cabinet, the necessary cooling capacity can be prepared exclusively or at least considerably with the aid of the air-air heat exchanger with a cooling machine. Combined refrigeration appliances of this type later in the application are also referred to as “hybrid refrigeration appliances”. Hybrid refrigeration appliances, which feature an air and air heat exchanger, have the disadvantage that, in the case where the ambient air temperature is above the temperature of the switch cabinet, heating of the storage cabinet would occur. distribution, if, in addition, the air-air heat exchanger were to flow through with warm ambient air, therefore, in the case of refrigeration apparatus known in the prior art, an expensive valve mechanism for bypassing the if mentioned, the ambient air of the heat exchanger. These mechanisms, however, are very expensive and complicated to handle.
    [004] In general, refrigeration circuits, which have a refrigeration machine or a cold water unit, which introduce the cold into the system and, in general, serve to cool a refrigeration medium are called refrigeration circuits " active". The cold water unit in the simplest case may have a cold water reservoir, the specialist will understand that "water" in refrigeration applications should not be designed restricting, but is only used as a synonym for refrigeration or refrigerants. of the prior art, generally referred to as "cooling medium". Consequently the “passive” refrigeration circuits do not feature any refrigeration machine and no cold water unit. In these cases, no active cooling of a cooling medium takes place.
    [005] Therefore the task of the invention is to prepare a generic distribution cabinet with a refrigeration appliance, in which the refrigeration appliance is built with simple technical means, and can also operate for low temperature differences between the theoretical temperature of the switch cabinet and the switch cabinet ambient air temperature passively, ie without the use of a refrigerating machine or a cold water unit.
    [006] This task is solved according to the invention by a switch cabinet with the characteristics of claim 1. Dependent claims 2 to 6 refer respectively to advantageous embodiments of the invention.
    [007] According to the invention, the refrigeration apparatus has a first air passage with a first air inlet and a first air outlet, which are open to the switch cabinet environment, and a second air passage with a second air inlet and a second air outlet, which are open to the internal space of the switch cabinet, whereby a condensing zone of the heat pipe arrangement is arranged in the first air passage, and in the second air passage. An evaporation zone of the heat pipe arrangement is arranged in the air, and the condensing zone and the evaporating zone respectively have a heat exchanger of cooling medium and air.
    [008] Preferably, the heat pipe arrangement comprises a gravitational heat pipe, the evaporation zone being arranged above the condensing zone. As a result, the first and second air passages should be arranged at least partially with respect to one another, such that the condensing zone is arranged at least partially above the evaporating zone.
    [009] Furthermore, in the first air passage an evaporator of the refrigerating machine or an air and water heat exchanger of the cold water unit is arranged, and in the second air channel a condenser of the refrigerating machine or a air and water heat exchanger of the cold water unit.
    [0010] In order to increase the efficiency of the refrigeration apparatus according to the invention, in an embodiment of the invention it is provided that the evaporator of the refrigeration machine is arranged in the direction of the air flow through the first passage of air behind the condensing zone of the heat pipe arrangement, and the condenser of the refrigerating machine is arranged in the direction of air flow through the second air passage behind the evaporation zone of the heat pipe arrangement.
    [0011] For the same purpose, in a refrigeration apparatus that combines an arrangement of heat pipes with a cold water unit, it may be provided that the air and water heat exchanger of the cold water unit is arranged in the direction of the air flow through the first air passage behind the condensing zone of the heat pipe arrangement or in the direction of air flow through the second air passage behind the evaporation zone of the heat pipe arrangement.
    [0012] In order to obtain a particularly compact form of construction of the first and second cooling medium circuit, as well as in order to obtain a heat exchange between the first and second cooling medium circuit through the exchanger in an embodiment of the invention, it is provided that the heat exchanger of cooling medium and evaporation zone air has a first conduction system for a first means of refrigeration, and a second drive system fluidly separated from the first drive system to a second cooling means, wherein the first and second drive system are thermally coupled together, and the first drive system drive is a component of the first circuit of the cooling medium and the second drive system is a component of the second circuit of the cooling medium.
    [0013] In this case, the first conduction system of the cooling medium and air heat exchanger of the evaporating zone can have or form an evaporator of the cooling machine or an air and water heat exchanger of the cold water unit.
    [0014] Alternatively or in addition, the condensing zone air and cooling medium heat exchanger may have a first drive system for a cooling media, and a second drive system separated by fluid from the first drive system for a second cooling means, the first and second driving system being thermally coupled to each other, and the first driving system being a component of the first circuit of the cooling medium and the second driving system being a component of the second circuit of the cooling medium.
    [0015] Likewise, in the case of the last mentioned embodiment, the first heat exchanger system for the refrigeration medium and condensing zone air heat exchanger may present or form a condenser of the refrigerating machine or an exchanger of air and water heat from the cold water unit.
    [0016] Other features of the invention will be clarified with the help of the figures below. In this case, the following are shown:
    [0017] In Figure 1 a heat exchanger with two conduction systems fluidly separated from each other and thermally coupled;
    [0018] In figure 2 a refrigeration arrangement according to the invention with a refrigeration apparatus executed as a wall-mounted apparatus, with a refrigeration machine and a heat pipe arrangement;
    [0019] In Figure 3 a refrigeration arrangement according to the invention with a refrigeration apparatus executed as a wall mounted apparatus, with a cold water unit in the internal circuit;
    [0020] In figure 4 a refrigeration arrangement according to the invention with a refrigeration apparatus implemented as a wall mounted apparatus, with a cold water unit in the external circuit;
    [0021] In Figure 5 a refrigeration arrangement according to the invention with a refrigeration apparatus implemented as a roof structure apparatus, with a cold water unit in the internal circuit;
    [0022] In Figure 6 a refrigeration arrangement according to the invention with a refrigeration apparatus implemented as a roof structure apparatus, with a cold water unit in the internal circuit;
    [0023] In figure 7 an arrangement of heat pipes for use in a refrigeration apparatus executed as roof structure apparatus according to figures 5 and 6; and
    [0024] In figure 8 a refrigeration apparatus according to the invention, in which an expansion means and a condenser of the refrigeration machine of the first circuit of the refrigeration medium can be covered optionally.
    [0025] In the case of the embodiment shown in Figure 1 of a heat exchanger of refrigeration medium and air 10 of the second circuit of the refrigeration medium, this heat exchanger is made in one piece with an evaporator or a heat exchanger. heat of air and water 12 of the first circuit of the cooling medium. The heat exchanger 10 has a first drive system 13, in which a first cooling means of the first circuit of the cooling means is driven, and a second drive system 14, in which a second cooling means of the second drive system is driven. The driving systems 13, 14 are respectively composed of parallel tubular tracks, which extend between two longitudinal ends of the heat exchanger 10. At the longitudinal ends the two parallel tubular lines are connected to each other in such a way that the cooling medium is guided between a respective advance of the cooling medium 15 and a return of the cooling medium 16. The heat exchanger 10 shown in FIG. 1 is designed to be passed through by a gas, for example, through its vertical longitudinal sides in the representation. air. The heat exchanger 10 has a large number of lamellas 17, the adjacent lamellas 17 respectively forming an air flow channel through the heat exchanger with each other. Furthermore, the lamellas 17 have the task of thermally coupling together the first and the second conduction system 13, 14 for heat exchange. In the case of the above-described flow direction of the air passing through the heat exchanger 10, the first and second conduction systems 13, 14 are arranged one after the other in the air flow direction. If the first driving system 13 is a component of a cooling medium circuit having a refrigerating machine or a cold water unit, and the second driving system 14 is a component of a cooling medium circuit having a arrangement of the heat pipe and, furthermore, it is provided that the cooling of the air passing through the heat exchanger 10 takes place preferably through the arrangement of the heat pipe, it can be provided that the refrigerating machine or the cold water unit is put into operation, then only if the cooling capacity made available through the heat pipe arrangement is not sufficient. Since the two drive systems 13, 14 are designed independently of each other, it is not necessary for the arrangement of the heat pipe to be deactivated for the connection of the refrigerating machine or the cold water unit. If the active refrigeration circuit is out of operation, and the refrigeration therewith has to take place through the passive refrigeration circuit, the piping of the conduction system 13 of the active refrigeration circuit in the first heat exchanger 10, due to the coupling of heat carried out with the aid of the lamellas 17, serve to increase the cooling capacity of the conduction system 14 of the passive cooling circuit. Even if with this the active refrigeration circuit is out of operation, its conduction system 13 is not useless in the heat exchanger 10. On the contrary, this system in this case serves to increase the degree of efficiency of the passive refrigeration circuit.
    [0026] Figure 2 shows a switch cabinet 1, in which the refrigerating appliance 2 is implemented as a wall-mounted appliance. The switch cabinet 1 comprises an internal space of the switch cabinet 9, whereby the refrigerating apparatus 2 is placed on an outer wall of the switch cabinet 1, and the internal space 9 of the switch cabinet 1 is in fluid connection with the second air passage 8 of the refrigeration apparatus 2 via an air inlet 6 and an air outlet 7. The air received in the switch cabinet 1 is transported with the aid of the fan 18 through the second air passage. air 8. In the second air passage 8 a second heat exchanger 10 according to the invention is arranged, according to FIG. 1. The heat exchanger in the second air passage 8 has an evaporator 11.1 and an evaporation zone 11.3 of an arrangement of heat pipes, in the direction of air flow the evaporation zone 11.3 being preceded by the second air passage 8 of the evaporator 11.1. Fluidly separated from the second air passage 8, the refrigeration apparatus 2 has a first air passage 5, which is in fluid connection with the environment of the switch cabinet 1 via an air inlet 6 and an air outlet 7. In turn, a fan 18 serves to transport ambient air through the inlet 6 to the first air passage 5 of the refrigeration apparatus 2. In the first air passage 5 a first heat exchanger 10 is arranged according to invention, according to FIG. 1, which is passed through by the air conveyed through the first air passage 5. The heat exchanger in the first air passage 5 has a condenser 11 and a condensing zone 11.2 of a tube arrangement. heat, whereby in the direction of air flow the condensing zone 11.2 is preceded by the first air passage 5 of the condenser 11.1. The heat exchangers 10 are in fluid connection with each other such that the first drive system 13 of the first heat exchanger 10 with the first drive system 13 of the second heat exchanger 10 forms a first medium circuit. closed refrigeration 3, and the second drive system 14 of the first heat exchanger 10 with the second drive system 14 of the second heat exchanger 10 forms a second closed refrigerant medium circuit 4.
    [0027] In the embodiment according to Figure 2, the first closed refrigeration medium circuit 3 is a closed refrigeration medium circuit driven by a compressor, with a compressor 19 and an expansion valve 20. Furthermore, the first heat exchanger 10, insofar as it refers to the first closed cooling medium circuit 3, has the function of a condenser, and the second heat exchanger 10, insofar as it refers to the first closed cooling medium circuit 3, has the function of an evaporator.
    [0028] The second closed cooling medium circuit 4 forms a heat pipe, also called heatpipe. Furthermore, the first heat exchanger 10 is arranged above the second heat exchanger 10. The second closed cooling medium circuit 4 is at least partially filled with a cooling medium. Cooling means suitable for heat pipe applications are known from the prior art and may comprise water. Conditioned by gravity, the liquid cooling medium accumulates in the lower area of the second closed cooling medium circuit 4, where the heat pipe evaporation zone is located. This zone just forms the second heat exchanger 10. The second heat exchanger 10 is passed through by hot air from the switch cabinet transported through the second air passage 8. In this case, the cooling medium of the second circuit of the closed cooling medium 4 is heated, as a result of which this medium evaporates at least partially. The evaporated cooling medium rises to the first heat exchanger 10, which just forms the condensing zone of the heat pipe. The first heat exchanger 10 is cooled by the cold ambient air from the switch cabinet 1, which is conveyed through the first air passage 5 by means of the fan 18, as a result of which the gas-shaped cooling medium is condensed in the first heat exchanger 10. The condensed cooling medium returns, activated by gravity, from the first heat exchanger 10 to the second heat exchanger 10 positioned lower and there it can evaporate again and rise again to the second heat exchanger 10.
    [0029] In this case, the refrigeration device 2 according to figure 2 can optionally be operated in three different refrigeration modes, that is, exclusively active, exclusively passive or hybrid, and in hybrid operation, in particular, it can it is foreseen that the passive refrigeration process is operated permanently, while the active refrigeration process serves, with the aid of the passive refrigeration process, to complete the available refrigeration capacity, in such a way that in total, at least, the capacity required refrigeration is made available, for which the active refrigeration process is timed.
    [0030] In figures 3 to 6 it is represented that, in essence, one and the same assembly of the refrigeration apparatus can serve the purpose of carrying out a whole variety of different refrigeration processes. In this case, the embodiments according to figures 3 and 4 refer to wall refrigeration appliances, and the embodiments according to figures 5 and 6 refer to refrigeration appliances, which are executed as ceiling constructions.
    [0031] Figure 3 shows a hybrid refrigeration apparatus with a cold water unit in the internal circuit. The first and second conduction systems 13, 14 of the first heat exchanger 10 in the first air passage 5 are connected in series, these systems together with the second conduction system 14 of the second heat exchanger 10 forming a tube. of heat. The second driving system 14 remaining from the second heat exchanger 10 forms the second closed cooling medium circuit 4 with a cold water source 21 and thereby a cold water unit. The cold water source 21 prepares chilled water, which is passed through the second heat exchanger 10, and is not a component of the refrigeration apparatus 2. Therefore, this additional active cooling medium circuit 4 can serve the purpose to make available, in case of high loss capacities of the components received in the internal space of switch cabinet 9, or in case of high ambient temperatures of switch cabinet 1, an additional cooling capacity, which is completed with the aid of the circuit. cooling means 3 the available cooling capacity, in such a way that sufficient cooling of switch cabinet 1 is provided in total.
    [0032] In particular, in the case of high ambient temperatures, corresponding to the construction according to figure 4, it may be appropriate to carry out the additional active cooling medium circuit 4 with the aid of the heat exchanger 10 integrated in the second air passage 8 In this case, the active cooling medium circuit in turn comprises a cold water unit.
    [0033] Figures 5 and 6 show that, similarly to figures 3 and 4, refrigeration appliances 2 can be made for ceiling mounting, which have high variability according to the invention. Also in the case of refrigeration appliances, which are made as roof constructions, the user is free to carry out the active refrigeration medium circuit 4 next to the passive refrigeration medium circuit 3 or in the external circuit through the first heat exchanger 10 (see figure 5), or in the internal circuit via the second heat exchanger 10 (see figure 6).
    [0034] Figure 7 shows an exemplary embodiment of a heat pipe arrangement, such as can be employed, in particular, in refrigeration appliances such as roof construction.
    [0035] The arrangement of heat pipes 24 comprises a conduction system, which is composed of pipe sections 25 guided vertically. The tube sections 25 are made up, respectively, of pairs of parallel tubes, which at their upper end are fluidly connected to each other with the aid of a U-shaped deflection piece. pipes of each tube section 25 into a common collector tube 26, which fluidly connects the tube sections 25 to each other. The heat tube arrangement 24 is subdivided into a condensing zone 24.1 and an evaporation zone 24.2 across of a final lamella 27 which extends horizontally, whereby, with the air and air heat exchanger 10 mounted, the condensing zone 24.1 is arranged in the first air passage of the refrigeration apparatus, and the evaporation zone 24.2 is arranged in the second air passage of the refrigeration appliance. The end lamella 27 serves for positioning and fixing the heat pipe arrangement 24 in a passage, which is carried out in an intermediate wall, which separates the first air passage from the second air passage. The pipes of the tube sections 25 are led through horizontally extending, thermally conductive lamellas 17 and are thermally coupled to these lamellas, between the adjacent lamellas 17, respectively, an air guide slit is formed. Therefore, the lamellas 17 extend especially in the direction of movement of air transported through the first air passage or through the second air passage, and serve to improve the heat exchange between the evaporation zone 24.2 or the condensing zone 24.1 and the air led through the respective air passage.
    [0036] In the conduction system of the heat pipe arrangement 24 a cooling medium is maintained, which due to the vertical alignment of the pipe sections 25 activated by the force of gravity, accumulates, above all, in the lower area of the pipe arrangement of heat 24 and thus in the collector tube 26 as well as in the evaporation zone 24.2. According to the invention, the evaporation zone 24.2 is arranged in the second air passage 8 of the refrigeration appliance and is thereby passed through by the hot air coming from the internal space of the switch cabinet 9. The hot air can exchange heat to the medium. cooling in the evaporation zone 24.2 via the thermally conductive pipes or lamellas 17, which as a result passes from the liquid aggregate state to the gaseous aggregate state, and migrates along the pipelines to the condensing zone 24.1 of the tube arrangement heat temperature 24. According to the invention, the condensing zone 24.1 must be located precisely in the first air passage 5 of the refrigeration device 2, such that this zone is fluid around precisely by the air from the cooled environment of the storage cabinet. distribution 1. This has the consequence that the gaseous refrigeration medium which is held in the condensing zone 24.1 of the heat pipe arrangement 24 can exchange thermal energy for the ambient air transported by the first air passage 3, over which this medium condenses and activated by the force of gravity, flows back from the condensing zone 24.1 to the evaporation zone 24.2.
    [0037] It is understandable that the conduction system and, in particular, its tube sections do not need to be aligned exactly vertically so that the functionality described above can be achieved. On the contrary, an angled arrangement of the heat pipe arrangement 24 in the refrigeration apparatus can also be envisaged, for example, in order to obtain a space-saving, lower construction height refrigeration apparatus.
    [0038] Figure 8 schematically depicts an alternative embodiment of the hybrid refrigeration appliance 2 according to the invention, with a first and a second heat exchanger 10 according to the invention, which thermally couple together a first. closed cooling medium circuit 3 and a second closed cooling medium circuit 4. The first closed cooling medium circuit 3 is an active cooling medium circuit, which in the direction of flow of the cooling medium presents one after the other a compressor 19, a condenser in the form of the upper heat exchanger 10, an expansion valve 20 and an evaporator in the form of the lower heat exchanger 10. The compressor 19 and the expansion valve 20 are bridged via a bypass line 22, each having a valve 23. In the closed position of the valves 23, the closed refrigerant circuit 3 can be actively operated. If the valves 23 are opened, then the heat exchangers 10 form an arrangement of heat pipes and with this a passive cooling medium circuit. The two cooling means circuits 3, 4 are arranged with respect to each other in such a way that the respective cooling means are transported in opposite directions from each other, if the first cooling means circuit 3 is actively operated. In the second closed cooling medium circuit 4 a second cooling medium is conducted between the evaporator and the condenser. The condenser and the evaporator are designed, respectively, in such a way that the two cooling medium circuits 3, 4 are thermally coupled to each other via the evaporator and the condenser. The condenser is arranged around a vertical range above the condenser. The condenser is arranged in a first air passage 5 of the refrigeration apparatus 2, formed by a first partial housing of the refrigeration apparatus, and the evaporator, as well as the compressor 19 and the expansion valve 20 are arranged in a second passage of air 8 formed by a second partial housing of the refrigeration appliance 2. Via the first air passage 5 and, in particular, through the condenser, ambient air is conveyed from the switch cabinet 1 with the aid of a fan 18. Through the The second air passage 8 and, in particular, through the evaporator, heated air is transported from the interior of the switch cabinet with the aid of another fan 18. The valves 23 in the bypass lines 22 are preferably electrically actuated solenoid valves.
    [0039] The second cooling medium in the second cooling medium circuit 4 is heated by hot air from the switch cabinet, which is conveyed through the second air passage 8, as a result of which this medium evaporates at least partially or its density at least decreases, such that it is transported along the second circuit of the cooling medium 4 from the evaporator to the condenser. The cooler ambient air from the switch cabinet passes through the condenser. In this way the cooling medium condenses or compresses in such a way that it flows, along the cooling medium circuit 4, back to the evaporator, in order to be heated there again by the hot air in the cabinet. of distribution. If the first cooling medium circuit 3 is likewise in passive mode of operation, then the cooling medium in that mode can also circulate in the manner described above with respect to the second cooling medium circuit 4, between the evaporator and the condenser. In this case, the transport direction of the first cooling medium in the first cooling medium circuit 3 is contrary to the drawn x-flow direction. The flow direction x drawn from the first cooling medium in the first cooling medium circuit 3 corresponds to that which forms during active operation of the first cooling medium circuit 3.
