    [0004] The present invention relates to a motor support assembly suitable for use in a heating, ventilating and / or air conditioning (HVAC) unit, the function of the HVAC unit being to condition an air flow of a motor vehicle.
    [0005]
    [0006] Said HVAC unit comprises, among other components, a constructive subassembly that is commonly referred to in the jargon as Motor Fan Group (GMV), which is formed by an electric motor that drives a fan centrifugal wheel, by a motor support in the manner of housing that supports said engine below, and generally by a damping system to prevent the transmission of noise and vibrations. Said Motor Fan Group are integrated into the complete HVAC unit.
    [0007]
    [0008] Second, the present invention also relates to a Fan Motor Group for an HVAC unit, the Fan Motor Group incorporating the improved motor support assembly defined in the first object of the invention.
    [0009]
    [0010] The particularity of the present invention is that said improved motor support assembly allows the efficient and economic integration of different types of electric ventilation motors and also of different sizes for the same motor support, ensuring an adequate cooling of the motor.
    [0011]
    [0012] BACKGROUND OF THE INVENTION
    [0013]
    [0014] Currently in the automotive industry is known the provision of a heating, ventilation and air conditioning unit (known in the jargon for its acronym in English HVAC: "Heating, Ventilation and Air Conditioning") to treat the air flow that It circulates inside the cabin of the vehicle and improves the comfort of the occupants of the vehicle, heating or cooling the air inserted or aspirated from the outside of the vehicle and distributing it towards the different passengers at the desired temperature.
    [0015] The HVAC unit is normally installed under the instrument panel of a vehicle, and is adapted to receive an external air flow from the outside or an internal flow (air recirculation) to the vehicle cabin and generate a flow of air conditioning inside the vehicle. the vehicle cabin according to specific comfort requirements.
    [0016]
    [0017] Generally, an HVAC air conditioning unit of a motor vehicle is composed of several air treatment devices, such as an air filter, to remove at least some particles from the incoming air flow, an air handling device such as a Motor Fan Group to generate an air flow through the HVAC unit, and treatment devices to heat and cool the air, including, among others, an evaporator and a heating radiator.
    [0018]
    [0019] The Fan Motor Group comprises a fan wheel and an electric motor capable of rotating the fan wheel, whose function is to drive the circulating flow of air through the HVAC air conditioning unit.
    [0020]
    [0021] The electric motor of the Motor Fan Group can be a direct current (DC) electric motor with brushes. However, the motor support assembly of the present invention could also be installed in fan assemblies equipped with other types of motors, other than a DC motor with brushes, but preferably with brushes, such as AC motors with brushes. For greater ease, from now on, we will refer to the electric motor of the fan indistinctly with the terms "motor" or "electric motor".
    [0022]
    [0023] The Fan Motor Group, in addition to the aforementioned fan wheel and electric motor, also comprises a lower part of the motor support, known in the jargon as "motor support", which has the function of supporting the weight of the motor and making that is in the correct position so that it can be electrically connected and the wheel operates freely.
    [0024]
    [0025] The indicated motor support, configured as a housing, serves, in addition to receiving and supporting the load of the fan motor below, to isolate the vibrations and absorb impacts, so it must be extremely durable and resistant to heat. In addition, they have to be easy to manufacture and assemble.
    [0026] The process of designing a new motor support for a particular motor of a Motor Fan Group is not an easy task, because it is limited especially by the space of the environment together with the need to cool the motor as detailed below.
    [0027]
    [0028] To meet the performance requirements in terms of air flow, adequate cooling of the motor installed within the Motor Fan Group of the HVAC unit is necessary, in order to maintain an acceptable level of efficiency and to guarantee the durability requirements of the motor. Specifically in brush motors, these brushes are the most critical heating point of all the components of these motors, so it is very important to send more direct air especially to the brushes. Electric motors used for fans in HVAC units benefit from cooling by the flow of air directed through the motor itself.
    [0029]
    [0030] Currently new engine mounts are designed so that this cooling air flows internally through the engine to thereby eliminate the heat generated by the brushes, coils, and / or electronic control elements, so that the engine runs efficiently and with reduced wear.
    [0031]
    [0032] Precisely the cooling restriction slows down the motor design and inevitably causes each new motor support design to be totally determined by the very specific design characteristics of each type, dimension and motor supplier that will be used in that fan assembly.
    [0033]
    [0034] The same motor support design does not generally fit for different types of motor. When a motor significantly smaller than the original (normally a medium power motor (eg 60mm diameter / 250W power) is placed inside a motor support designed for a high power motor (eg 75mm / power 320W) ), due to the increase of free volume, the air flow received by the motor is not enough to cool it, only in very few cases the same motor support is able to receive different types of motor ensuring an optimal cooling of the motor, but in no case Case motors of different sizes.
    [0035]
    [0036] Therefore, it is inevitable that designers must review and redesign for each type and size of engine a unique engine support, whenever a new engine is introduced into a fan assembly. This customization of the motor supports for each motor entails very high design and manufacturing costs because there is a large number of references of different motor supports.
    [0037]
    [0038] Therefore, the design of the motor support is nowadays a very expensive and long process, since it demands that it be specific and very specific for each type and size of motor.
    [0039]
    [0040] In view of the foregoing, there is a clear need for an improved design of a motor support assembly for an HVAC unit, which allows the use of electric ventilation motors of different type and size for the same motor support at a low cost and with great efficiency in the flow of adequate circulation of cooling air through and in the vicinity of the engine.
    [0041]
    [0042] Likewise, there is also a need for an improved design of a Motor Fan Group for an HVAC unit, which incorporates a motor support assembly, which allows the use of electric ventilation motors of different type and size for the same motor support with a low cost and with great efficiency in the flow of adequate circulation of cooling air through and in the vicinity of the engine.
    [0043]
    [0044] Description of the invention
    [0045]
    [0046] The first object of the present invention is to provide an improved motor support assembly suitable for use in a ventilation and / or air conditioning (HVAC) unit of a motor vehicle, which solves the aforementioned drawbacks and presents the advantages described then.
    [0047]
    [0048] According to a first aspect, the present invention provides a motor support assembly for a heating, ventilation and / or air conditioning (HVAC) unit, the motor support assembly being configured to receive an electric motor for a centrifugal fan, and also for supporting the lower end of the shaft of said electric motor, said motor support assembly comprising a motor support in the form of a housing, characterized in that it also comprises a dividing partition capable of being traversed by the axis of said motor and sized to be coupled inside the housing at the same time as it is in contact with the motor, in such a way that it blocks the passage of the cooling air flow in the contact area of the dividing wall with the motor.
    [0049] The second objective of the present invention is to provide a Fan Motor Group to be used in an HVAC unit, comprising the following components: an electric motor, a centrifugal fan wheel and the claimed improved motor support assembly, solving said Fan Motor Group the aforementioned drawbacks and presenting the advantages described below.
    [0050]
    [0051] As indicated above, this electric motor may be a brushless direct current (DC) motor, or an alternating current (AC) motor with brushes, although the improved motor support assembly of the present invention may also be suitable for accommodate another type of equivalent ventilation motors.
    [0052]
    [0053] The surprising effect achieved with the provision of this dividing wall in the lower part of the motor support is that a specific volume of the lower area of the motor support is closed or almost closed. This achieves that the cooling air does not escape to that lower zone (which is why it is not convenient to circulate), and therefore direct as much as possible to the motor and its brushes to be optimally cooled.
    [0054]
    [0055] As regards the configuration of the dividing wall, it is preferably formed by a bending body, capable of being deformed sufficiently but without breaking so that it can be positioned perfectly and immovably inside the motor support.
    [0056]
    [0057] Preferably the dividing partition is provided with a central hole to allow passage of the lower end of the motor shaft. Said central hole, therefore, has a diameter slightly greater than the lower end of the large drive shaft.
    [0058]
    [0059] Preferably the dividing wall has a thin body, of small thickness, made of a material such that it allows it to be deformable, so that it can flex sufficiently, acquiring a final shape slightly convex but without breaking. It has a preferred thickness comprised between 0.5 and 10 mm.
    [0060]
    [0061] In a possible embodiment of the present invention, because the motors have a mostly circular configuration, the motor supports are usually also circular, so that the body of the dividing wall may have an outer contour of perimeter circular or sensibly circular, to adapt to these common circular shapes of the motor and the motor support. However, other possible external shapes of the dividing wall could be applied in order to adapt to different configurations of motor supports, without this modifying the essence of this piece.
    [0062]
    [0063] Optionally, the body of the dividing partition may have in its outer peripheral area a groove that emerges from its outer contour towards the interior, and whose function is for the correct assembly of the dividing partition. Said groove has the advantageous function of anti-terror system for mounting the dividing partition always in the same position with respect to the motor support. This slit is always placed in the same position on the motor support. By way of example, the slit has a rectangular shape, of greater width and less depth. However, other diverse forms may be possible.
    [0064]
    [0065] Also optionally, the body of the dividing wall may comprise one or more cutting lines arranged emerging from the outer contour towards the interior of the body. Advantageously, said cutting line (s) has the function of allowing an appropriate and safe assembly, since they make the fitting in one or more points of the motor supports and at the same time retain the dividing wall so that they do not fall during assembly. The number, orientation and length of this cutting line (s) in the dividing wall will depend on each specific configuration of the inner surface of the motor support. In general, this line (s) of cut will be from 1 to 6 lines and will be lines of shorter length than the diameter of the partition.
    [0066]
    [0067] Preferably, the body of the dividing wall has an initially flat upper and lower surface which advantageously, when deformed at the time of its assembly, end up adopting a final, substantially convex working shape. This deformation of the central part during assembly is possible thanks to the degree of flexibility of the material with which the partition is combined with its thickness.
    [0068]
    [0069] In a possible embodiment of the present invention, the assembly of the dividing wall in the motor support is as follows: the body of the originally flat dividing wall is supported by its outermost part in the internal part of the motor support, leaving the dividing wall higher of the position of the motor and then the motor is positioned in its position inside the motor support and in that position pushes the central part of the dividing wall, which causes it to acquire a slightly convex final shape. In this final situation, it is advantageous to create a more forceful contact between the engine-partition divider-engine support that allows air to pass through the motor and conveniently refrigerate it.
    [0070]
    [0071] In a possible embodiment of the invention, the dividing partition in its working position is arranged in an orientation perpendicular to the motor axis, and at the height of the lower end of the motor, creating at least one perimeter contact zone between the dividing wall and the partition wall. inner surface of the motor support.
    [0072]
    [0073] According to a specific embodiment of the invention, the dividing partition when assembled has three different perimeter contact zones (C1, C2, C3): a first contact perimeter zone (C1) between the outermost part of the dividing wall and an inner wall of the partition wall. engine support; a second contact perimeter zone (C2) between the lower end part of the engine and the central area of the partition wall in the vicinity of the central hole, and a third contact perimeter zone (C3) between another inner wall of the motor support and another area outside the dividing wall. These perimeter contact zones of the dividing wall may vary, without affecting the essential nature of the invention, and may be more or less zones of contact between said dividing wall and the internal parts of the motor support and the lower part of the motor.
    [0074]
    [0075] After the holder carried out various empirical tests with different thicknesses, he was able to confirm that the body of the dividing partition, thin and deformable, preferably has a thickness comprised between 0.5 and 10 mm. This thickness parameter will depend to a great extent on the type of material to be used; that is, the thickness of the partition is directly related to the rigidity of the type of material used to manufacture the dividing wall.
    [0076]
    [0077] Also preferably, the dividing wall manufacturing material is preferably permeable to water, since it has been found that water tightness can become a problem.
    [0078]
    [0079] Also preferably, the dividing wall is made of a material which, in addition to being flexible enough to be slightly deformed by the weight of the motor without breaking, is breathable, so that the air flow is directed through the motor and not through the dividing wall. Therefore, the dividing wall manufacturing material is preferably non-porous. However, the non-porosity of the material is not a determining requirement, since air pressures are limited in this area of the HVAC, which is why alternatively the material may be porous.
    [0080]
    [0081] As for the manufacturing material of this dividing partition, it can be manufactured from a plastic film (also commonly referred to by the English term "film"), which preferably has a thickness of 0.5 to 2 mm. It is flexible enough to deform slightly due to the action of the motor assembly without breaking, it is also a type of economical material with which to make the dividing wall.
    [0082]
    [0083] Alternatively, it can also be made of foam material, eg polyethylene foam (PE), but other foams or similar materials such as, for example, polyurethane foam (PUR) or EPDM ( Ethylene Propylene Diene Monomer "), or other equivalents The thickness of the baffle made of foam that has shown better results is preferably between 4 and 6 mm In the same way as the previous case, the partition made of foam with a thickness Between 4 and 6 mm, it has enough flexibility to deform slightly due to the action of the motor assembly without breaking, it is also a type of economic material with which to make the dividing wall.
    [0084]
    [0085] In short, both previously described materials, the plastic film and the foam, have excellent characteristics of flexibility and non-breathability, required to solve the technical problem of the invention.
    [0086]
    [0087] As the shape and materials of the dividing partition object of the invention are so simple, it can be easily and economically produced through, for example, a stamping process. This process of manufacturing by stamping gives a considerable advantage by its reduction of costs and times, since it gives the possibility of encompassing other processes also more economical than the injection: forming (covers also thermoforming), die-cutting (covers cutting and stamping) and molded (covers low injection / high pressure with / without temperature).
    [0088]
    [0089] Alternatively, but with a somewhat higher cost, the dividing wall can also be manufactured by a plastic injection process.
    [0090]
    [0091] Also, alternatively, the dividing wall can be manufactured by a thermoforming process.
    [0092] With the particular and simple configuration of the dividing wall body exposed above, advantageously no specific design feature is required on the support side of the motor to position said dividing wall, since it is simply positioned by contact and engaging said element with the inner walls of the motor support. Therefore, by not requiring any modification to the motor support for the positioning of the dividing partition object of the invention, the manufacturing cost of the fan motor group is very low since it will only affect the manufacturing cost of the partition itself, that due to its formal characteristics is low. This also translates into a substantial gain in terms of minimizing development costs, shorter development times and a higher level of standardization.
    [0093]
    [0094] In addition, thanks to its simple and efficient configuration, this dividing partition is fully compatible with the assembly process of the fan motor group, as well as being very easy and quick to manufacture and assemble in the motor support.
    [0095]
    [0096] Brief description of the figures
    [0097]
    [0098] For a better understanding of what has been exposed, some drawings are attached in which, schematically and only by way of non-limiting example, a practical case of realization of the fan motor group is represented.
    [0099]
    [0100] Figure 1A is a front view of a conventional fan motor group for an HVAC unit, in which the motor support is designed specifically for a particular electric motor of ventilation, diameter 75 mm and 320 W, with its corresponding centrifugal fan wheel .
    [0101]
    [0102] Figure 1B is the same front view of the same conventional fan motor group as the previous figure, in which the motor of 75 mm and 320 W has been changed by a smaller motor, diameter 60 mm and 250 W.
    [0103]
    [0104] Figure 2 is an exploded view of the various components of the fan motor group object of the present invention, in which the dividing partition disposed between the motor support and the motor has been incorporated.

    [0106]
    [0107] Figure 4 is a front view of a second embodiment of the fan motor group object of the invention that the previous figure, but with the difference that in this case the dividing wall is made of plastic film, with a somewhat smaller thickness .

    [0110]
    [0111] Figure 6 is a sectional upper view of the fan motor group object of the invention, in which the dividing partition mounted on the motor support has been seen.
    [0112]
    [0113] Figure 7 shows three different views of different positions of the dividing wall assembly: Figure 7A shows the initial position of the dividing wall on the lower part of the motor support with a first contact perimeter zone (C1) between both parts, specifically between the the outermost perimeter zone of the dividing wall with an interior wall of the motor support; Figure 7B shows the next mounting position, in which the motor is positioned on said partition wall; and Figure 7C shows the third mounting position in which the central part of the partition wall has been deformed downwards by the weight of the motor so that two more contact zones are created: a second contact perimeter zone (C2) between the lower end part of the engine and the central area of the dividing partition, and a third contact perimeter zone (C3) between another wall of the engine support and another outer perimeter zone of the dividing wall.
    [0114]
    [0115] Figure 8 shows a graph of temperature with respect to time in two different situations: with and without the dividing wall in an EP 61 mm engine integrated into a motor support designed by a motor greater DPO 73 mm.
    [0116]
    [0117] Description of a preferred embodiment
    [0118]
    [0119] Next, an embodiment of the fan motor group (10) is described with reference to FIGS. 1 to 7.
    [0120] As seen in figure 1A, the conventional fan motor group (10) for an HVAC unit, in which the motor support is designed with specific measures for a certain electric motor for ventilation, in this case with a diameter of 75 mm and 320 W, has an air flow (A) that does reach the brushes of the motor (2) and refrigerates them correctly.
    [0121]
    [0122] In contrast, in Figure 1B, the same fan motor group (10) as Figure 1A is shown but changing the motor (2 ') of 75 mm and 320 W by a smaller motor (2' '), diameter 60 mm and 250 W. In this case, it can be seen how the air flow (A) does not reach the motor brushes (2) as it escapes from the bottom (see arrow in dashed).
    [0123]
    [0124] Figure 2 shows in an exploded way the different components that form the fan motor group (10) for an HVAC unit, in which the dividing partition (5) of the present invention disposed between a motor support (3) and a electric motor (2).
    [0125]
    [0126] Figures 3 and 4 show the partition (5) already mounted inside a possible motor support (3), specifically installed in an arrangement perpendicular to the axis (6) of the engine (2), and at the height of the end lower (6a) of the motor (2). By covering much or all of the space between the lower end (6a) of the engine (2) and the inner perimetral area of the engine support part (3) that remains at the height of the lower end of the engine, the area remains closed or almost closed so that the air flow (A) does not escape through the lower area of the motor support (3), and is directed towards the motor (2) and its brushes.
    [0127]
    [0128] In these figures 3 and 4 two different embodiments of the dividing partition (5) are shown: in figure 3 it is made of foam with a thickness preferably comprised between 4 and 6 mm., And in figure 4 it is made of plastic film with a thickness preferably comprised between 0.5 and 2 mm.
    [0129]
    [0130] A possible configuration of the dividing partition (5) can be seen more clearly in Figure 5, which illustrates an example of realization of the partition (5), consisting of a substantially circular body of upper and lower surfaces originally flat , of small thickness provided with a central hole (8) for the passage of the lower end (6a) of the motor shaft (3). In this case, the body of the dividing partition (5) has an indentation (11) in its outer perimeter zone (7), with a rectangular plan, emerging from its outer contour towards the interior and whose mission is for the correct assembly of the dividing wall. Said slit (11) is always mounted in the same position with respect to the motor support (3), see figure 6. Also in this case the body of the partition (5) has several cutting lines (9) arranged emerging from the outer contour (7) towards the inside of the body. In many cases the motor support (3) has small walls of about 1 mm. of thickness, in which these lines of cuts (9) provided on the surface of the dividing wall are fitted perfectly, which at the same time retain the dividing wall so that it does not fall during the assembly, see figure 6.
    [0131]
    [0132] The assembly of the dividing partition (5 ') in a possible embodiment is shown in three different steps in figures 7A to 7C: the body of the dividing wall of foam (5') originally flat is supported by its outermost perimeter part in a part internal part of the motor support (3) forming a first contact zone (C1), leaving the highest dividing wall of the position the motor must have (Fig. 7A), and then starting to introduce the engine (2) higher ( Fig. 7B) until it reaches its final position inside the motor support (3) and in that position pushes the central part of the dividing partition (5 '), which causes it to acquire a slightly convex final shape (Figure 7C). In this final situation (Figure 7C), the dividing wall has two different perimeter contact zones on the outer part of the dividing wall with the lower part the motor support (perimeter areas C1 and C3), and a perimeter contact zone (Figure 7C). C2) in the innermost part of the dividing wall with the lower part of the motor shaft (6a).
    [0133]
    [0134] Advantageously, these three different contact perimeter zones (C1, C2 and C3) of the dividing partition (3), which can be more or less perimeter zones of contact of the partition (3) with the motor support and / or with the motor, guarantee that a contact is created and very strong, solid and effective coupling between motor support (3) -tabique partition (5) -motor (2), thereby reducing the excess air volume and consequently substantially improving the cooling of a small engine inside the motor support designed for a larger motor.
    [0135]
    [0136] With reference to figure 8, two different situations of the motor (2) are represented in it: in positive brush and in negative brush. In both cases, the temperature of the motor, specifically the temperature in the brushes, with and without the provision of the partition (5, 5 ', 5 ") object of the present invention has been measured with a data recording device. In the representation of the different temperature curves, it is clearly observed as a smaller motor (specifically an EP 61 mm motor) integrated into a motor support designed specifically for a larger motor (specifically a DPO 73 mm motor) shows lower temperatures in both situations (positive brush and negative brush). Specifically for the positive brush, the temperature decrease is of 10 to 15 ° C average, while for the negative brush this decrease is of average 9 to 12 ° C.
    [0137]
    [0138] It is, therefore, fully empirically proven that such a decrease in temperature is due solely and exclusively to a greater cooling of the engine when incorporating the dividing partition, which avoids the loss of air flow in excess volume of the motor support.
    [0139]
    [0140] Although reference has been made to a specific embodiment of the invention, it is obvious to a person skilled in the art that the described motor support assembly and the fan motor group are susceptible to numerous variations and modifications, and that all the details mentioned can be replaced by other technically equivalent, without departing from the scope of protection defined by the appended claims.
