    The invention relates to the field of ventilation, heating and / or air conditioning installations. The invention relates in particular to a motor support assembly for such an installation.
    A heating, ventilation and / or air conditioning system of a vehicle, in particular an automobile, is generally used to distribute air into the passenger compartment of the vehicle.
    In such an installation, the circulating air flow is propelled by a motor-blower unit, also called blower, which is mounted on the casing of the heating, ventilation and / or air conditioning system at a volute of the housing ensuring the ducting of the air flow generated by the fan motor unit. The motor-fan unit comprises in particular a fan wheel housed in the volute to generate a flow of air therein, and a motor support assembly comprising an electric motor adapted to rotate the fan wheel and a motor support. Conventionally, the motor is controlled by a control module.
    The motor support is generally secured to the housing of the heating, ventilation and / or air conditioning system. According to a known solution, the motor support also carries the control module. Generally, it is the engine mount that allows to mount the engine support assembly on the housing of the heating, ventilation and / or air conditioning, more precisely on the level of the volute.
    The engine support then forms a shutter cover of an opening of the volute on one side thereof.
    The engine support is therefore critical for the integration of the engine support assembly in the installation and must meet many requirements such as sealing against a risk of water intrusion, aeraulic performance, or a noise level expected in the vehicle.
    It is also known to provide on the engine support one or more cooling channels carrying a flow of cooling air preferably taken from inside the volute and conveyed to the engine and also advantageously to the engine control module. Thus, the engine mount must also meet a cooling requirement of the engine and / or the control module.
    Depending on the type of heating, ventilation and / or air conditioning installation, the housing, and especially the volute, may be of different design. It is necessary to adapt in particular the motor support intended to be fixed on the volute.
    Also, vehicles may be provided to be available both in driving on the right, that is to say with the steering wheel on the right side, than on the left side, that is to say with the steering wheel on the left, the steering column is in this case may be arranged differently and thus the arrangement of the elements under the hood is generally modified. This requires to provide motor-fan units specifically adapted to the side of the pipe.
    According to the known solutions, the motor-fan unit, and in particular the motor support assembly, is designed specifically for each application. There is no fan motor unit or standard motor support unit.
    Consequently, for each type of heating, ventilation and / or air conditioning installation, it is necessary to adapt in particular the motor support assembly of the motor-fan unit. In particular, the engine support, which allows among other things the assembly of the motor support assembly on the volute of the housing of the heating, ventilation and / or air conditioning system in the motor vehicle, must be modified.
    Or the redesign and / or modification of the parts of the motor-fan unit can be long, especially for the engine mount which is a multifunctional part and therefore complex.
    This is binding and requires the design of the engine support assembly for the motor-fan unit exclusively according to a specific choice previously defined according to the needs of the car manufacturer. The invention therefore aims to at least partially overcome these problems of the prior art by providing a motor support assembly including assembly on the vehicle, for example on a heating, ventilation system volute and / or air conditioning, can be adapted in a simple way according to the needs of the car manufacturer. To this end, the subject of the invention is a motor support assembly for a heating, ventilation and / or air-conditioning installation, in particular for a motor vehicle, intended to be mounted at the level of a volute of the heating installation, ventilation and / or air conditioning, the engine support assembly comprising: - a motor, and - an engine support, characterized in that it further comprises a connecting piece, on the one hand, assembled to the engine support and, d on the other hand, intended to be assembled to the volute, so as to form an interface between the motor support and the volute, the connecting piece and the motor support being two separate parts.
    The motor is in particular a brushless motor, also called self-driven synchronous machine with permanent magnets.
    The connecting piece therefore allows an adaptation of the motor support assembly depending on the application. Indeed, one can obtain several configurations of the motor support assembly, and therefore the motor-fan unit comprising such a motor support assembly, which differ from each other by the connecting piece. Thus, depending on the heating installation, ventilation and / or air conditioning, it is the connecting piece that varies while the other elements can be the same from one configuration to another and therefore be standardized.
    It is therefore no longer imperative to design a specific engine support for each application.
    This results in a reduction in the manufacturing cost of the engine support assembly and a time saving for adaptation to various heating, ventilation and / or air conditioning systems. In particular, this results in a standardization of the most complex parts such as the motor support and the control module support. Depending on the context and production volumes, this standardization can lead to a reduction in production costs.
    This results in a reduction in the costs and development time of an application, which can be an advantage in the case of a retrofit project (ie replacement of a product already in production).
    Said engine support assembly may further comprise one or more of the following features, taken separately or in combination.
    According to one aspect of the invention, the connecting piece has a first face facing the motor support and a second opposite face intended to cooperate with the volute.
    On the motor support side, the first face of the connecting piece may be invariant from one configuration of the motor support assembly to the other as far as it is shaped for assembly with the motor support which may be a standard piece.
    On the other hand, the adaptation is done at the level of the second face of the connecting piece which is intended for assembly on the volute of the housing of the heating, ventilation and / or air conditioning installation and is therefore likely to change according to the application. It suffices to adapt the design, in other words the design, of the second face intended to interface with the volute, and in particular with a fan wheel housed in the volute, for each application.
    According to another aspect of the invention, the second face of the connecting piece has a substantially smooth surface. Thus, the design of the second face of the connecting piece is optimized to correspond to a better interface with the air flow, that is to say so as to reduce the risk of disturbance of the air flow in the volute.
    According to a preferred embodiment, the connecting piece comprises at least one guide portion of a cooling air flow having an air inlet at the second face and opening at the first face.
    The or each guide portion of the cooling air flow is intended to be traversed by a flow of cooling air from the volute so as to circulate the flow of cooling air in the motor support assembly for cooling the elements carried by the engine support, namely the engine and / or a control module adapted to control the engine and also mounted on the engine support. It is therefore the connecting piece that integrates the cooling function of the engine in particular, and no longer the motor support as in the solutions of the prior art. The motor support can be simplified.
    According to another aspect of the invention, the connecting piece has a central axis, and the first and second faces extend in planes parallel to each other and perpendicular to the central axis.
    According to a particular embodiment, the connecting piece has at least one flange arranged radially outside the receiving zone of the engine support and comprising said at least one guide portion of the cooling air flow.
    The motor and the connecting piece are coaxial. The connection between the motor support and the connecting piece on the one hand, and between the connecting piece and the volute housing the fan wheel on the other hand, is along the same axis.
    Advantageously, the connecting piece is made of a plastic material. This allows a simple and inexpensive realization of such a connection piece which provides several functions, including mounting of the motor support assembly on the volute, interface between the motor support and the volute, and guiding a cooling air flow to cool the engine in particular.
    According to one embodiment, the motor support assembly comprises an engine control module and a support of the control module assembled to the engine support, the control module being disposed on the support of the control module on the opposite side to the engine support. The assembly formed by the control module, the support of the control module and the motor support is assembled to the connection piece.
    The support of the control module advantageously serves as bearing support for the motor.
    Thus, the entire block formed by the control module, the support of the control module, the motor and the motor support can be assembled to the volute via the connection piece. As a result, all these elements can be standard regardless of the heating, ventilation and / or air conditioning system in which the motor support assembly is to be integrated. The invention also relates to a motor-fan unit of a heating, ventilation and / or air-conditioning installation, the motor-fan unit comprising an engine support assembly as defined above and a fan wheel that can be driven by the engine of the engine support assembly.
    According to one aspect of the invention, the connecting piece is intended to be interposed between the motor support and the fan wheel, when the motor-fan unit is mounted in the heating, ventilation and / or air conditioning system.
    The connecting piece thus forms an interface between the motor support and the fan wheel intended to be driven by the motor and intended to be received in the volute, so as to move a flow of air in the latter.
    According to one aspect of the invention, the second face of the connecting piece opposite to the first face arranged facing the motor support is arranged opposite the fan wheel, when the motor support assembly is mounted in the installation. heating, ventilation and / or air conditioning.
    Advantageously, the second face of the connecting piece has a shape complementary to the shape of the fan wheel, so as to allow assembly by shape cooperation between the connecting piece and the fan wheel housed in the volute.
    According to one embodiment, the second face of the connecting piece has a substantially flat shape.
    According to another embodiment, the second face of the connecting piece has a substantially curved annular shape in the direction of the fan wheel. The invention also relates to a heating, ventilation and / or air conditioning system for a motor vehicle characterized in that it comprises a volute and at least one motor support assembly as defined previously mounted on the volute.
    Only the connection piece of the engine support assembly is variable depending on the heating, ventilation and / or air conditioning system, all other elements of the engine support assembly may be standard. This allows a quick adaptation as a single piece, the connection piece, must be designed specifically to allow integration into the heating, ventilation and / or air conditioning, and save time.
    For example, the connecting piece may be designed to allow the assembly of the motor support assembly, and in particular of the motor-fan unit comprising this motor support assembly, in a heating, ventilation and / or air-conditioning installation as well for a vehicle adapted for driving on the left than for a vehicle adapted for driving on the right.
    According to one aspect of the invention, the volute has an opening on one side of the volute opposite an intake of an air flow and the motor support assembly is arranged on the volute so as to seal the opening of the volute.
    In this way, the motor support assembly, once mounted on the volute, and in particular on the fan wheel housed in the volute, through the connecting piece can set the air flow to the Inside the volute and the forced air flow is guided to an outlet of the volute opening advantageously in an air duct of the heating, ventilation and / or air conditioning system.
    According to an additional aspect of the invention, the connecting piece comprises a substantially cylindrical skirt and a flange at the periphery of said skirt. The flange of the connecting piece is arranged facing the periphery of the fan wheel, when the motor support assembly is mounted in said installation. Other features and advantages of the invention will appear more clearly on reading the following description, given by way of illustrative and nonlimiting example, and the appended drawings in which: FIG. 1 is a perspective view of a motor-fan unit comprising a motor support assembly according to the invention mounted on a volute of a heating, ventilation and / or air-conditioning installation; - FIG. 2 is an exploded view of an engine support assembly according to FIG. invention and a volute of a heating, ventilation and / or air-conditioning system, - Figure 3 shows standard elements of the motor support assembly of Figure 1 or 2 can be assembled without distinction with a piece of connection according to a first or a second embodiment, - Figure 4 is a first enlarged partial view of a portion of a connecting piece of the motor support assembly of the FIG. 1 or 2, assembled to a volute of a heating, ventilation and / or air-conditioning installation, and FIG. 5 is a second enlarged partial view of a part of a connection piece of the support assembly. motor of Figure 1 or 2, assembled to a volute of a heating, ventilation and / or air conditioning, showing a guide portion of a cooling air flow provided on the connecting piece.

    The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments.
    In the description it is possible to index certain elements, in other words one can for example mention a first element or a second element. In this case, it is a simple indexing to differentiate and name elements close, but not identical. This indexing does not imply a priority of one element, compared to another. Such denominations can easily be interchanged without departing from the scope of the present invention.
    FIG. 1 represents a motor-fan unit, also called a blower, for a heating, ventilation and / or air-conditioning installation equipping, for example, a motor vehicle.
    The motor-fan unit comprises a motor support assembly 1 intended to be mounted on a housing of the heating, ventilation and / or air conditioning installation comprising, according to the embodiment described, a casing 2 in the form of a volute, -after designated volute 2.
    The volute 2 is for example shaped substantially spirally. By way of nonlimiting example, the volute 2 can be made by assembling two half-volutes 2a and 2b.
    The motor-fan unit is intended to be arranged so as to circulate a flow of air in a duct of the heating, ventilation and / or air conditioning system. The volute 2 is connected to this air duct and allows to introduce the flow of pulsed air by the motor-fan unit in the air duct. The air duct of the heating, ventilation and / or air conditioning system distributes the air flow to outlet mouths (not shown) opening in the passenger compartment of the vehicle.
    More specifically, the motor support assembly 1 of the motor-fan unit is intended to be mounted on the volute 2, in particular at an opening on one side of the volute 2, advantageously opposed to an intake of a flow of air in the volute 2. Π may be an outside air flow taken outside the passenger compartment, or a flow of air taken inside the passenger compartment said flow of recycled air, or a mixture of an outside air flow and a recycled air flow. The opening on the side of the volute 2 is thus closed by the motor support assembly 1.
    As best seen in Figures 2 and 3, the engine support assembly 1 comprises a motor 3 and a motor support 11 described below.
    The motor-fan unit comprises in addition to the motor support assembly 1, a fan wheel 5 intended to be housed in the volute 2 and intended to be driven by the motor 3, so as to ensure the setting in motion of the flow of in the volute 2. More specifically, a flow of air is sucked and circulated by the fan wheel 5 and is extracted from the volute 2 by an outlet connected to the air duct of the heating installation, ventilation and / or air conditioning ·
    Regarding the engine 3, it is in particular a brushless motor 3 (also called self-driven synchronous machine with permanent magnets). The motor 3 comprises a fixed stator and a rotor movable with respect to the stator and capable of driving the fan wheel 5.
    The motor 3 is arranged around a longitudinal axis A, corresponding to the axis of rotation of the motor 3. The motor 3 comprises a transmission shaft 4 extending along the longitudinal axis A. The transmission shaft 4 is for example arranged substantially in the center of the motor 3. In this example, the transmission shaft 4 protrudes from the motor 3 thus having a free end.
    The motor 3 and the fan wheel 5 are here coaxial.
    The fan wheel 5 is mounted on the transmission shaft 4 of the engine 3.
    According to the particular exemplary embodiment illustrated in FIG. 2, the fan wheel 5 has in turn at least one part 7 having a substantially bowl shape, this part is subsequently designated by bowl 7. The bowl 7 is of substantially concave shape. With reference to FIG. 2, the concavity of the bowl 7 is oriented towards the inside of the volute 2, when the motor support assembly 1 is mounted on the volute 2. In addition, according to the particular embodiment illustrated in FIG. 4 or 5, the fan wheel 5 has a flat portion formed at the periphery of the bowl 7, the side intended to cooperate with the motor support assembly 1, as will be detailed later. In other words, the bowl 7 ends with this flat. The flat part extends in this example substantially orthogonally with respect to the axis A.
    Referring again to FIG. 2, the fan wheel 5 further comprises a central hub 8, for receiving the free end of the transmission shaft 4 of the engine 3. The fan wheel 5 may furthermore have a generally cylindrical general shape comprising blades or vanes 9 which extend in this example from the periphery of the bowl 7, in a direction substantially parallel to the longitudinal axis A of the motor 3. In other words, according to the particular embodiment illustrated in FIG. Figures 4 and 5, the blades or vanes 9 extend away from the flat at the periphery of the bowl 7 and substantially orthogonal to this flat.
    As stated above, the engine support assembly 1 further comprises a motor support 11.
    According to the embodiment illustrated in Figures 1 and 2, the motor support 11 has a generally circular general shape.
    The motor support 11 is for example made of plastic material.
    Once the engine support assembly 1 assembled on the volute 2, the engine support 11 protrudes laterally on the side of the volute 2, as is best seen in Figure 1.
    The side of the volute 2 having the opening closed by the motor support assembly 1, in particular by the motor support 11, extends for example in a plane perpendicular to the axis A.
    In order to allow the motor support 11 to be assembled on the volute 2, the motor support assembly 1 further comprises a connection piece 15 or 15 'interposed between the motor support 11 and the volute 2. The connecting piece 15 or 15 is arranged to make the connection between the motor support 11 on one side and the volute 2 for housing the fan wheel 5 on the other side.
    FIG. 1 shows a motor support assembly 1 with a connection piece 15 according to a first embodiment, and in FIG. 2 a motor support assembly 1 with a connecting piece 15 'according to a second embodiment.
    This connecting piece 15, 15 'can be adapted as required. Indeed, as shown diagrammatically in FIG. 3, according to the heating, ventilation and / or air conditioning installation in which the motor support assembly 1 must be integrated, the same motor support 11 can be assembled to a connection piece 15. or 15 'different.
    The connecting piece 15 illustrated in FIGS. 1 and 3 can for example be adapted for a volute 2 of a first type of heating, ventilation and / or air-conditioning installation, while the connecting piece 15 'illustrated on FIG. Figures 2 and 3 may for example be adapted for a volute 2 of a second type of heating, ventilation and / or air conditioning. By way of nonlimiting example of different types of heating, ventilation and / or air-conditioning installation, a heating, ventilation and / or air conditioning system configured for a vehicle having a left-hand or a heating, ventilation and / or air-conditioning system configured for a right-hand drive vehicle.
    The connecting piece 15 or 15 'therefore forms an interface between on the one hand the motor support 11 and on the other hand the volute 2 and the fan wheel 5 housed in the volute 2 in the assembled state of the support assembly motor 1, and in particular of the motor-fan unit, on the housing of the heating, ventilation and / or air-conditioning system.
    This connecting piece 15, 15 'can be made of a plastic material, such as polypropylene for example, simply and inexpensively.
    The connecting piece 15, 15 'has a central axis which in this example coincides with the longitudinal axis A of the motor 3. In other words, the motor 3 and the connecting piece 15, 15' are arranged around the same axis A, and are therefore coaxial. The connection piece 15, 15 'to the volute 2 is assembled along an assembly axis coinciding with the central axis of the connecting piece 15, 15' and the longitudinal axis A of the motor 3. From even the assembly of the engine support 11 to the connection piece 15 is along the same axis of assembly coincides with the central axis of the connecting piece 15, 15 'and the longitudinal axis A of the motor 3.
    The connecting piece 15, 15 'is here intended to be fixed at the periphery of the opening of the volute 2. The fixing can be done by any appropriate means, for example by screwing. According to the illustrated example, the volute 2 may have fixing studs 20 projecting from the volute 2 extending axially, in this example, substantially parallel to the axis A, and intended to engage and pass through associated and complementary ports 150 provided on the connecting piece 15, 15 '.
    In order to allow the connection piece 15, 15 'to be mounted on the volute 2, the connecting piece 15 or 15' has a general shape complementary to the shape of the volute 2. More specifically, the connecting piece 15 or 15 has a shape complementary to the shape of the inner surface defined by the volute 2. By way of example, as illustrated in FIGS. 3 to 5, the connecting piece 15, respectively 15 ', has a substantially cylindrical skirt 15a, respectively 15'a. The axis of revolution of the cylindrical skirt 15a or 15'a is according to the example described the axis A.
    The cylindrical skirt 15a, respectively 15'a, is adapted to bear against an inner wall of the volute 2, when the motor support assembly 1 is mounted in the heating, ventilation and / or air conditioning system.
    Referring to the arrangement of the elements in Figures 3 to 5, the cylindrical skirt 15a, respectively 15'a, here forms a lower portion of the connecting piece 15, 15 'respectively.
    The connecting piece 15, respectively 15 ', furthermore has, according to the embodiments of FIGS. 3 to 5, a flange 15b, respectively 15'b, at the periphery of the cylindrical skirt 15a, respectively 15'a, on the side of the connecting piece 15, respectively 15 ', intended to be assembled with the volute 2. More precisely, the flange 15b, respectively 15'b, is intended to be arranged opposite the fan wheel 5, when the support assembly motor 1 is fitted in the heating, ventilation and / or air conditioning system. In particular, the collar 15b, respectively 15'b, is for example adapted to be arranged opposite the flat at the periphery of the bowl 7 of the fan wheel 5.
    The flange 15b (see Figures 4 and 5) may extend substantially orthogonal to the cylindrical skirt 15a. The flange 15b may be substantially flat.
    Alternatively, it can be provided that the collar has a substantially convex shape towards the volute 2 when the motor support assembly 1 is mounted on the volute 2.
    Referring to the arrangement of the elements in Figures 3 to 5, the flange 15b, respectively 15'b, here forms an upper portion of the connecting piece 15, 15 'respectively.
    Finally according to a particular embodiment, visible in Figures 4 and 5, there may be a projection 15c at the free end of the flange 15b. In this example, the projection 15c extends away from the cylindrical skirt 15a and the flange 15b. The projection 15c may extend substantially orthogonally to the flange 15b. The projection 15c here extends substantially parallel to the axis A. In this case, the upper part of the connecting piece 15 is in two parts 15b and 15c.
    Furthermore, the connecting piece 15 or 15 'has a first face 151 and a second face 152 or 152' opposite to each other.
    The first face 151 serves as an interface with the engine support 11 and is designed to allow assembly with the engine support 11. The first face 151 is for example defined in particular by the face of the flange 15b or 15'b which is arranged next to the engine mount 11.
    The second face 152 or 152 'is intended to form an interface with the volute 2 and is provided to allow assembly with the volute 2. The second face 152 or 152' is for example defined by the face of the flange 15b or 15 b which is arranged opposite the flat at the periphery of the bowl 7 of the fan wheel 5, when the motor support assembly 1 is mounted in the heating, ventilation and / or air conditioning system.
    The two faces 151 and 152, respectively 151 and 152 ', are in planes parallel to each other and perpendicular to the central axis A of the connecting piece 15, respectively 15'.
    According to a preferred embodiment, the side of the engine support 11, the first face 151 may be substantially the same, or even standard, that is to say, it can remain unchanged between different embodiments of the room connection 15, 15 '. On the other hand, the second face 152, 152 'on the side of the volute 2 may be different according to the embodiments, since it is this second face 152, 152' which is changed to allow adaptation to different volutes 2 as a function of the heating, ventilation and / or air conditioning installation in which the motor support unit 1 must be integrated.
    The engine support 11 can therefore be a standard part regardless of the heating, ventilation and / or air conditioning system, and only the connecting piece 15, 15 ', and more precisely its second face 152 or 152', is adapted to the needs or requirements of this installation.
    In other words, the motor support 11 can be adapted to any volute 2 for any heating, ventilation and / or air conditioning installation via a connection piece 15 or 15 'which is defined accordingly. With the same standard motor support 11, it is possible to obtain configurations of the motor support assembly 1, and therefore of the motor-fan unit, which differ from one another by the connecting piece 15, 15 '.
    Advantageously, on the side of the volute 2 and the fan wheel 5, the connecting piece 15 or 15 'is designed with the least possible asperities. To do this, the second face 152, 152 'has a substantially smooth surface, that is to say devoid as much as possible of irregularities or cavities. This reduces the generation of noise or disturbance of the air flow in the volute 2. This specific adaptation to the air flow in the volute 2 is more obvious to achieve on the connecting piece 15, 15 'than on the engine support 11 which was used as an interface with the volute in the solutions of the prior art and was therefore a very complex piece.
    In particular, the second face 152, 152 'of the connecting piece 15, 15' is of complementary shape to the shape of the bowl 7 of the fan wheel 5.
    According to an exemplary embodiment, the second face 152 of the connecting piece 15 may be substantially flat.
    As a variant, it is possible for the second face 152 'of the connecting piece 15' to have a substantially curved annular wall in the direction of the volute 2, or here of the fan wheel 5, when the motor support assembly 1 is mounted on the volute 2.
    Furthermore, on the motor support side 11, the connecting piece 15, 15 'is for example intended to be fixed at the periphery of the motor support 11.
    To enable attachment of the connecting piece 15, 15 'to the motor support, the connecting piece 15, 15' may have fixing pins 153 (better visible in FIG. 4) which project from the first face 151 and extend axially from the first face 151 towards the motor support 11. According to this example, the fixing pins 153 extend substantially parallel to the central axis A of the connecting piece 15, 15 '. The fixing pins 153 are intended to pass through associated orifices of the motor support 11 during assembly. In order to ensure a mechanical connection between, on the one hand, the motor support 11 and the elements which it carries and on the other hand the connecting piece 15, 15 ', it is possible to deform the fixing pins 153, for example according to a method of pegging, after passing through the motor support 11. Of course any other appropriate means may be provided for the assembly of the connecting piece 15, 15 'to the motor support 11, in particular by screwing or by clipping. The fixing pins 153 are for example provided on the face of the flange 15b or 15'b arranged opposite the engine support 11.
    The connecting piece 15 or 15 ', according to one or other of the embodiments illustrated in FIGS. 2 to 5, may also comprise several stiffening ribs 154. The stiffening ribs 154 are for example provided on the face of the flange 15b or 15'b arranged opposite the engine support 11.
    Advantageously, the connecting piece 15, 15 'additionally integrates a cooling function of the motor 3.
    More specifically, with reference to FIG. 5, the connecting piece 15, 15 'may comprise at least one guide portion 155 of a cooling air flow coming from the inside of the volute 2. For this purpose , the or each guide portion 155 of a cooling air flow is arranged in aeraulic communication with the volute 2, more precisely with an air flow channel 16 provided on the volute 2, on the side of the volute 2 carrying the engine support assembly 1, in the assembled state of the engine support assembly 1 on the volute 2. According to the illustrated example, the flow channel 16 extends substantially parallel to the longitudinal axis A of the motor 3 coincides with the central axis of the connecting piece 15, 15 '. The air flow channel 16 is for example substantially cylindrical in shape. Of course, any other form can be considered. In addition, the air flow channel 16 is arranged on the volute 2 on an outside part at the opening receiving the fan wheel 5 of the motor-fan unit, here near the periphery of the opening of the volute 2. More precisely, the air flow channel 16 is arranged radially outside the opening receiving the fan wheel 5.
