Description

The invention is in the field of ventilation, heating and / or air conditioning systems, in particular for a motor vehicle. The invention relates in particular to a control and cooling assembly for such an installation. The invention relates more precisely to a control module for a blower and an evaporator of such an assembly.

Heating and / or ventilation and / or air conditioning systems for motor vehicles, also known by the English name HVAC (for Heating, Ventilation and Air-Conditioning) allow air to be distributed in a passenger compartment of the vehicle and generally include a duct air in which are arranged various means of thermal air treatment. The air heat treatment means are in particular heat exchangers, for heating and / or cooling, for example an air heating radiator and an evaporator intended to cool the air. Generally, in an air conditioning mode of a heating and / or ventilation and / or air conditioning installation, a refrigerant circulates in an evaporator, the latter being traversed by the air flow in order to cool this air flow.

The air flow circulating in the heating and / or ventilation and / or air conditioning installation is generated by a motor-fan unit, also called a blower, which is mounted at a volute of the installation ensuring the channeling of the air flow. The air flow is directed, via the blower, to one or more exits of the installation opening into the passenger compartment, after being heat treated.

The blower includes in particular a fan wheel or turbine housed in the volute to generate a flow of air therein, and an electric drive motor capable of rotating the fan wheel. Conventionally, the blower, and more specifically the drive motor, is controlled by a control module. The control module makes it possible in particular to vary the speed of the motor as required and for this purpose comprises components, more particularly electrical and electronic components, including electronic power components, in particular active electronic power components. We can cite for example semiconductors such as diodes, transistors, in particular insulated gate field effect transistors known by the acronym MOSFET for "Metal Oxide Semiconductor Field Effect Transistor". As opposed to passive components

-2 which cannot introduce energy into the circuit to which they belong and which cannot be modified, the active components can change state and lead or block energy.

One problem is the cooling of the control module. Indeed, in operation the temperature of the control module can rise and if it exceeds a predefined maximum temperature it may damage certain elements of the control module such as power electronic components or a printed circuit board electrically connected to these latter.

To dissipate the heat generated by the control module, it is known to associate it with a heat sink or heat dissipation radiator. The heat sink generally has fins which are arranged to be exposed to the air flow generated in the volute. For this purpose, the heat sink is generally disposed at the outlet of the volute, which requires a distance between the control module and the drive motor to be controlled.

In addition, the fins of the heat sink in the path of the air flow leaving the volute can cause flow disturbances and pressure drops. Finally, the heat generated by the components of the control module may not be dissipated well enough.

The object of the invention is to ensure effective cooling of the components of the control module while reducing the electrical connections, the space requirement, and the pressure losses.

To this end, the subject of the invention is a control and cooling assembly, for a heating and / or ventilation and / or air conditioning installation, in particular of a motor vehicle, comprising a blower configured to generate an air flow, said assembly comprising :

an evaporator configured to be traversed by the air flow generated by the blower, and a blower control module.

According to the invention, the evaporator and the control module comprise complementary assembly means making it possible to mount the control module on the evaporator, so that the control module is in thermal contact with the evaporator.

-3We understand by "thermal contact", the fact that the control module is arranged in direct contact with the evaporator, without intermediary, or is arranged indirectly on the evaporator with the interposition of one or more thermal conductors, so as to allow in either case the conduction of the heat generated by the control module to the evaporator.

This takes advantage of the low temperature of the evaporator to cool the elements of the control module, such as electronic power components. The arrangement of the control module on the evaporator makes it possible to dispense with the fins intended to be exposed to the flow of air as in the solutions of the prior art. The evaporator is therefore used as a source of cooling for the control module.

Said assembly may also include one or more of the following characteristics, taken separately or in combination:

the assembly means are configured to allow mounting and maintaining the control module in mechanical contact with the evaporator;

the control module comprises at least one electronic power component configured to be arranged in thermal contact with the evaporator;

the control module comprises at least one heat sink for dissipating the heat generated by said at least one electronic power component of the control module, configured to be arranged in thermal contact with the evaporator;

said at least one electronic power component is arranged on the evaporator with or without interposition of the printed circuit board;

the printed circuit board is arranged on the heat sink;

-4said at least one electronic power component is arranged on the heat sink;

said at least one electronic power component is arranged on the heat sink with or without interposition of the printed circuit board;

said at least one electronic power component is connected by at least one electrical connection member to the printed circuit board;

the coating material is a thermal conductive material;

The invention also relates to an evaporator for a heating and / or ventilation and / or air conditioning installation, in particular for a motor vehicle, configured to be arranged in a control and cooling assembly as defined above.

According to one aspect of the invention, the evaporator comprises a casing delimiting an internal volume of circulation of a coolant, and has on an outside wall of the casing a means of assembling the control module.

The following embodiments 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 characteristics apply to a single embodiment. Simple features of different embodiments can also be combined or interchanged to provide other embodiments.

FIG. 1 schematically shows part of an installation

-61 heating and / or ventilation and / or air conditioning, hereinafter referred to as installation 1, in particular for a motor vehicle. Such an installation 1 comprises a motor-fan unit also called a blower or air blower 3 (see FIGS. 1 and 2), capable of generating an air flow.

The installation 1 comprises a volute 5, in which the blower 3 is intended to be mounted, and which ensures the channeling of the air flow generated by the blower 3.

The scroll 5 can have a substantially spiral shape. The volute 5 then has a contour starting with an area called "volute nose" and which evolves to an exit 51.

In operation, the blower 3 makes it possible to direct the air flow to a duct 7 for re-installation 1 which distributes the air flow to the outlet openings opening into the passenger compartment of the vehicle. To do this, the volute outlet 51 is connected to the duct 7.

Before entering the passenger compartment, the air flow can undergo at least one heat treatment, for example it can be heated or cooled. To this end, the installation 1 further comprises one or more heat exchangers arranged in the duct 7 intended to be traversed by the air flow. In particular, the installation 1 includes an evaporator 9 in particular for performing an air conditioning function. The installation 1 may include other heat exchangers downstream of the evaporator 9 according to the direction of flow of the air flow in the duct 7 not shown in FIG. 1.

The blower 3 comprises a motor 31 and a wheel 33 also called a fan wheel or a blower wheel, intended to be driven by the motor 31, so as to set the air flow in motion. The motor 31 is configured to drive the fan wheel 33 in rotation about an axis of rotation A.

The fan wheel 33 is housed inside the volute 5. On one of its sides, the volute 5 has an opening closed by a cover 11 forming a support for the motor 31 to drive the fan wheel 33. The motor 31 and the fan wheel 33 are coaxial.

In the example illustrated, the fan wheel 33 has a generally substantially cylindrical shape, with an open face. The open side is on the side opposite the

-7 cap 11 forming engine support. This open face is, in the assembled state of the blower 3 in the installation 1, in aeraulic communication with one or more air inlets 11 (see FIG. 1), for example outside air coming from outside the passenger compartment and / or recirculated air from the passenger compartment, installation 1.

The fan wheel 33 is configured to suck in through this open face an air flow as shown diagrammatically by the arrow F1 in FIG. 2, then to evacuate this air flow from the side, that is to say here radially with respect to the axis of rotation A, as shown schematically by the arrows F2 in FIG. 2, when it is driven in rotation. The air sucked in and circulated by the fan wheel 33 is extracted from the volute 5 by the outlet 51.

According to the embodiment shown in FIG. 2, the fan wheel 33 has a part 331 forming a bottom, for example substantially in the shape of a bowl, which is arranged opposite the open face of the fan wheel 33. The fan wheel 33 further comprises a hub 333, for example substantially in the center of the bowl-shaped part 331, for receiving a free end of a drive shaft of the motor 31. The fan wheel 33 may comprise a plurality 335 blades or fins. The blades 335 in this example extend axially from the periphery of the bowl-shaped part 331.

The invention relates in particular to a control and cooling assembly 13, for such an installation 1. The control and cooling assembly 13, hereinafter designated by “assembly 13”, is better visible in FIGS. 3 to 5b .

This assembly 13 includes the evaporator 9, and a control module 15 of the blower 3. In other words, the evaporator 9 and the control module 15 are respectively configured to be arranged in the assembly 13. In particular, the module control 15 is intended for and configured to be arranged on the evaporator 9, while being in thermal contact with the evaporator 9. More specifically, the control module 15 is arranged on the outside of the evaporator 9.

By two elements in “thermal contact” is meant the fact that they are arranged in direct contact with one another, we speak in particular of mechanical contact, without intermediary, or that they are assembled one to the other. other indirectly with

-8interposition between these two elements of one or more thermal conductors, so as to allow in one or the other case the conduction of heat between these elements.

To be assembled one to the other, the evaporator 9 and the control module 15 each comprise complementary assembly means 16 (with reference to FIGS. 1 and 3). The assembly means 16 are configured to allow mounting and maintaining the control module 15 in mechanical contact with the evaporator 9. The thermal contact between the module 15 and the evaporator 9 is for example ensured by mechanical means such as a spring, one or more screws, by clips, by cold brazing of the heat sink 157 on the evaporator 9, etc.

The complementary assembly means 16 can be any suitable assembly means. Mention may be made, in a non-exhaustive manner, of means for screwing, clipping, clipping or else an assembly may be provided by bonding or welding. In the example shown very schematically, and by way of nonlimiting illustration, in FIG. 1 or 3, the assembly means 16 are screwing means comprising screws 161, assembly tabs 150 provided on the control module 15 having passage openings for the body of each screw 161 and a contact area of the evaporator 9 having holes (not visible) into which the screws 161 are screwed. For example, it is possible to arrange a cavity on a wall of the evaporator 9 to receive the control module 15.

With regard more precisely to the evaporator 9, when it is placed in the duct 7 of the installation 1, as shown diagrammatically in FIG. 1, it is configured to be traversed by the air flow generated by the blower 3 .

In the air conditioning mode of installation 1, the air flow is cooled as it passes through the evaporator 9.

The evaporator 9 comprises a casing 91 defining an internal volume for the circulation of a fluid, such as a refrigerant fluid. In the example illustrated in FIG. 3, the evaporator 9 is of generally parallelepipedal shape. The air flow, the flow of which is shown diagrammatically by the arrows F2, passes through the two large opposite faces of the evaporator 9. For this purpose, the casing 91 does not cover the faces of

-9the evaporator 9, here the two large opposite faces, through which the air flow passes through the evaporator 9.

Fluid inlet and outlet pipes 17 (shown diagrammatically in FIG. 3) make it possible to connect the evaporator 9 to a circuit of the refrigerant fluid (not shown). When the evaporator 9 is crossed by the air flow generated by the blower 3 (not visible in FIG. 3), the air flow is cooled by heat exchange with the refrigerant circulating inside the evaporator 9.

The control module 15 is intended to be arranged on the outside of the evaporator 9, in other words on an outside wall of the casing 91 on the side opposite the circulation volume of the refrigerant. According to the embodiments described, the control module 15 is not arranged on the large faces of the evaporator 9 which are intended to be traversed by the air flow generated by the blower 3.

The evaporator 9 therefore has on the outer wall an assembly means 16 configured to cooperate with a complementary assembly means 16 of the control module 15.

Referring again to FIG. 1, the control module 15 makes it possible to control the blower 3. More precisely, it makes it possible to control the motor 31, for example the speed of rotation of the motor 31.

The location of the control module 15 on the evaporator 9 as shown in FIG. 1 is by way of illustration and is not limiting. The control module 15 can be arranged on another surface of the evaporator 9, in particular of the outer casing 91 of the evaporator 9. The location of the control module 15 can be chosen to limit the length of conductive cables between the control module 15 and the blower 3.

Different variant embodiments of the control module 15 are shown in FIGS. 4 to 7.

The control module 15 comprises a printed circuit board 151 having an electrical supply circuit for the blower 3 (not visible in FIGS. 4 to 7). The printed circuit board 151 is in the form of a plate. The power circuit

-10electric is printed on a large face of the printed circuit board 151.

The printed circuit board 151 can be arranged in different orientations, as described in more detail below.

The control module 15 further comprises one or more electronic components, including at least one electronic power component electrically connected to the electrical supply circuit. In particular, the control module 15 comprises at least one active power electronic component 153, designated hereafter by "active component". In contrast to a so-called passive component, such as a resistor, which does not allow energy to be introduced into the circuit to which it belongs or to increase the power of a signal and which cannot be modified, a component active 153 is an electronic component that increases the power of a signal, can change state and lead or block energy. We can also speak of a controllable component. Most of these include semiconductors, such as diodes, transistors, in particular insulated gate field effect transistors known by the acronym MOSEET for "Metal Oxide Semiconductor Eield Effect Transistor".

The printed circuit board 151 can support the active component 153. By this is meant that the printed circuit board 151 forms a mechanical support for the active component 153. In particular, the active component 153 can rest largely or even entirely on the printed circuit board 151 (as shown schematically in Figure 6). In particular, the active component 153 can rest on a large face of the printed circuit board 151. The active component 153 can be fixed, for example soldered on the printed circuit board 151.

As a variant or in addition, the printed circuit board 151 can support any other electronic power component and / or electrical component of the control module 15.

As an alternative, the active component 153 can be connected by at least one electrical connection member, such as lugs or electrical connection pins 154, to the printed circuit board 151, in particular to the circuit (as shown diagrammatically in FIG. 7). . This configuration with the active component 153 remote from the printed circuit board 151, makes it possible to limit the risks of damage to the printed circuit board 151 due to a too high temperature of the active component 153. Indeed, the printed circuit board

-11151 is more limited in temperature than the active component 153. The printed circuit board 151 can reach a maximum temperature of the order of 150 ° C. while the active component 153 can reach a maximum temperature greater than 150 ° C., in particular around 175 ° C.

Similarly, in the examples of FIGS. 4 to 5b, the active component 153 is electrically connected to the circuit of the printed circuit board 151 by at least one electrical connection member, not shown. As before, such an electrical connection can also apply to any other electronic power component and / or electrical component of the control module 15.

In addition, the printed circuit board 151 is electrically connected to one or more connectors 155 to receive a supply voltage and / or speed control signals from the motor 31 and to supply the necessary power to the motor 31 ( shown schematically in Figure 1). For the sake of simplicity of the drawings, the electrical connections between the control module 15 and the motor 31 are not shown in FIG. 1.

The printed circuit board 151 is arranged in thermal contact with the evaporator 9. To do this, it can be fixed to the evaporator 9. It can be a direct fixing, that is to say without part intermediate between the printed circuit board 151 and the evaporator 9. An example of such a direct fixing is shown diagrammatically in FIG. 4. This fixing can be done by any suitable means, for example by gluing or welding, for example at the level of a cavity of a wall of the evaporator 9 or not.

In FIG. 4, the printed circuit board 151 is shown arranged with a small face against a surface of the evaporator 9. It may be the edge or the longitudinal end face.

According to an alternative, not shown, the printed circuit board 151 can be arranged with the large face opposite to the large face presenting the printed circuit against a surface of the evaporator 9.

Advantageously, the control module 15 can comprise at least one heat sink 157, shown diagrammatically in FIGS. 5a to 7, to dissipate the heat generated in particular by the electronic power components, such as the

-12 active component 153, of the control module 15. The heat sink 157 is made of a thermally conductive material. It is for example a metal part.

This heat sink 157 is arranged in thermal contact with the evaporator. To do this, it can be arranged and fixed on the evaporator 9, more precisely on an outer wall of the casing 91.

Such a heat sink 157 is connected to ground.

When such a heat sink 157 is provided, the printed circuit board 151 can be arranged and fixed on the heat sink 157 which is fixed to it on the evaporator 9. This fixing can be done by any suitable means, for example by gluing or welding. As before, the printed circuit board 151 can be arranged with a small face on the heat sink 157 (FIGS. 5a, 5b). It can be the edge or the longitudinal end face. As a variant, the printed circuit card 151 can be arranged with the large face opposite to the large face presenting the printed circuit, on the heat sink 157 (FIGS. 6, 7).

The active component 153 and / or any other electronic power component can be arranged on the heat sink 157 with the interposition of the printed circuit board, as illustrated in FIG. 6. In other words, the active component 153 and / or any other electronic power component rests on the printed circuit board 151 itself resting on the heat sink 157. The fixing between these different elements can be done by any suitable means, for example by gluing or welding.

As a variant, the active component 153 and / or any other electronic power component can be arranged and fixed, by any suitable means, to the heat sink 157 without interposition of the printed circuit board 151 as illustrated in FIG. 7. This configuration improves the dissipation of the heat generated.

One can provide, as shown schematically in Figures 4 to 5b, a heat dissipation sole 158 on which is mounted an electronic power component such as the active component 153. Such a sole 158 is for example metallic.

-13According to a variant illustrated in Figure 4, the heat dissipation sole 158 can be arranged on the evaporator 9 and fixed by any suitable means.

According to a variant illustrated in FIG. 5a or 5b, the heat dissipation soleplate 158 can be arranged and fixed on the heat sink 157. The heat dissipation soleplate 158 is separate from the heat sink 157. It is therefore another piece and / or other material.

Furthermore, the control module 15 can be provided with a cover 159 which covers the elements of the control module 15, so as to form a housing, as illustrated in the examples of FIGS. 4 to 5b. The cover 159 can be made of plastic. The cover 159 is attached to the dissipator 157 (FIGS. 5a, 5b) or it can be envisaged as a variant that it is attached to the evaporator 9 (FIG. 4), so as to cover all of the elements of the control module 15 Advantageously, the cover 159 has a passage for an outlet from the connector 155.

The arrangement of such a cover 159 to form a control module box 15 is more evident by cooperation with the heat sink 157 as described above (see FIGS. 5a, 5b). In this case the heat sink 157 and the cover 159 are of complementary shapes. For example, the heat sink 157 may have a flange, for example folded, at the periphery of the surface intended to accommodate the printed circuit board 151 and / or the active component 153 or other component of the control module. The cover 159 is for example fixed to this rim by covering the various elements carried by the heat sink 157 directly or indirectly.

In addition, such a housing can be more easily assembled on the evaporator 9. It may not be necessary to modify the evaporator 9 for this purpose. For example, the housing formed by the heat sink 157 and the cover 159 can be assembled on the wall of the evaporator 9 without necessarily requiring a cavity at the latter.

As illustrated in FIG. 5b, the control module 15 can comprise a coating material 19. Such a coating material 19 or encapsulation is known by the name "potting" in English. This coating material 19 covers or envelops the elements which are inside the control module 15, namely the

-14 printed circuit board 151, electronic and / or electrical components such as the active component 153, the connector 155, and the possible heat sink 157. The coated elements have no inside the housing delimited by the cover 159, no free part or exposed to air or the environment outside the control module

15.

Advantageously, the coating material 19 fills the interior volume of the control module 15 or more precisely of the control module housing 15 closed by the cover 159. Such filling is more easily achievable when a heat sink 157 as described above allows the housing to be closed by cooperation with the cover 159.

The coating material 19 chosen must be suitable for electronics. In particular, it must be electrically insulating. It is advantageously heat resistant. Furthermore, it is a thermal conductive material, in particular of better thermal conductivity than air. This makes it possible to promote the cooling of the control module 15 by participating in the dissipation of the heat generated by the elements of the control module 15, in particular the electronic power components.

Such a material 19 makes it possible in particular to ensure a seal. In fact, the coating material 19 protects the elements inside the control module 15 from any ingress of water or dust.

The coating material 19 can be chosen from the following materials: thermal gel, silicone, especially epoxy resin, polyurethane, for example two-component polyurethane or else a hot fluid material and cold solid. The coating material 19 can therefore be a material capable of changing state. For example, it may be a polyurethane resin which is liquid when filling the interior of the control module 15 and which then hardens.

Furthermore, an opening (not shown) can be made in the duct 7 of the installation 1, near the evaporator 9, so that the control module 15 is accessible. Thus, in the event of a failure, the control module 15 can be removed from the evaporator 9 and extracted from the installation 1. The reassembly of another control module 15 can be easily done by this same opening.

Thus, the complementary assembly means 16 of the evaporator 9 and of the control module 15 make it possible to position and fix the control module 15 in thermal contact with the evaporator 9.

In operation, the evaporator 9 is at a low temperature, in particular of the order of 2 ° C., and forms a cooling source for the control module 15. The control module 15 therefore benefits from the low temperature of the refrigerant which flows through the evaporator 9.

When the evaporator 9 does not work, although it rises in temperature, 10 in particular at room temperature, the evaporator 9 forms a thermal mass and the heat from the control module 15 is dissipated through this thermal mass.

Efficient cooling of the control module 15 is therefore obtained by thermal conduction due to the arrangement of the control module 15 on the evaporator 9.
