- Module 1 represents a centralized module 1 for temperature management and battery cooling.
- Module 1 is provided with electromechanical components with a fluidic function, also called actuators, consisting here of a multi-way solenoid valve 3 and two pumps, as well as a degassing tank 5. These elements are arranged on a support plate 2 and comprise a proximal end, enclosing a mechanical device such as a possibly multi-port valve or a turbine, received in housings 25 of the plate as shown in Figure 2.
- the mechanical devices of the actuators act on the circulation of the coolant contained in one or more coolant circulation channels 23 made in the support plate 2 by openings 30, 31, 32, 33, 34 as shown in Figure 3.
- the circulation channels 23 are made between an upper cover 21 and a lower cover 22 of the plate 2 at least partly recessed on the upper cover side in the lower cover.

- the printed circuit comprises extensions 61 bypassing the circulation channels 23 and provided with connection tracks to connect the printed circuit with first electrical connectors 62, 63 which pass through openings 26, 26' of the upper cover 21.
- the extensions 61 of the printed circuit are housed in a bulge 22a of the lower cover 22 just as the electronic card of the management controller 6 is received in a housing 22b of this lower cover 22.
- the bases 62 emerging from the openings 26 receive the connectors 71 for the pumps 4, the base 63 emerging from the opening 26' receives the connectors for the electromagnetic valve (or solenoid valve) and the base 64 on the through printed circuit the opening 28 receives a power cable from the module and its electromechanical components with fluidic function.
- the first electrical connectors are intended to receive first complementary electrical connectors 71, 73 from said actuators 3, 4 to connect the controller 6 to the control electronics of the solenoid valves 4 and the pump 3 as will be seen later.
- the positioning of the controller between the lower and upper covers of the plate 2 on the one hand protects it and on the other hand allows the entire mass of the plate to be used to cool the controller and the transistors, IGBT (bipolar transistor insulated gate bipolar transistor) or other switching components arranged on the controller and intended to provide the electrical power to the actuators.
- the connectors 62, 63 can be bases with male or female contacts to which complementary connectors are connected, for example plugs provided with contacts of the opposite gender to the contacts of the bases.
- the printed circuit 60 comprises a second electrical connector 64 for receiving a second complementary electrical connector for powering the controller and for connecting with a computer for controlling the controller (not shown) of known type.
- the second electrical connector also passes through the upper cover 21 of the plate through an opening 28, thus making the connection of the module centralized on the plate.

- joints arranged between the upper cover and the lower cover around the channel locations 23 are provided to prevent coolant leaks.
- layers of insulating varnish or insulating sheets can be placed on and under the printed circuit and its extensions to electrically insulate it from the covers.
- the lower 22 and upper 21 covers can be assembled by welding. In this case, the weld bead runs around the perimeter of the channels 23. The weld bead then replaces the joints and prevents leaks.
- the present disclosure also proposes electromechanical components with fluidic function, also called actuators, configured to cooperate with the module described previously.
- These components here consist of a solenoid valve or electromagnetic valve 3, for example an 8-way valve and pumps 4.
- the pumps 4 have a parallelepiped shaped body while the valve has a cylindrical body without this being restrictive.
- the pumps comprise a distal end 4a provided with an electrical control circuit 41, an example of which is shown schematically in Figure 4, and a proximal end 4b provided with a mechanical pumping member, for example a turbine of known type not shown, in a housing 42 of the body 4, intended to pump the liquid between a first channel of the module and a second channel of the module or a pipe connected to the module.
- the electromagnetic valve comprises on its distal end an electromechanical control module 3a managing its positions.

- conductive tracks for example a flexible circuit directly connecting the printed circuit 41 disposed in the housing of said distal end of the actuator and carrying the electronic control of said actuator to the first complementary connector constituted here by the plug 71.
- Figures 5 and 6 represent more precisely the degassing tank 5 configured to allow the heat transfer fluid to undergo degassing making it possible to separate a gas, in particular air, present in the heat transfer fluid.
- This reservoir is mounted on the plate 2 in a removable manner and comprises to do this as shown in Figure 6 at least one latching member 52, 52a configured to cooperate by latching with a complementary latching member 54 on a support 53 integral with the plate 2.
- This support 53 can be part of the plate, 2 for example of the lower cover 22 or, alternatively, be a separate part assembled with the plate.
- two latching members in the form of tabs 52 provided with hooking clips 52a received in housings 54 are produced.
- the reservoir is connected to the fluid circuit of the plate via an end piece 51 received in a fluid connection port 29 making a channel of the support plate communicate with an interior volume of the degassing tank 5.
- the support 53 forms a support face for the tank above the connection port fluidic 29, the two legs 52 and the end piece 51 providing a triangle fixing of the tank on said support face for better stability of the fixing of the tank on the module.
- the degassing tank makes it possible to rid the heat transfer fluid of air bubbles before it goes to a cooling circuit. This allows the cooling circuit to function properly.
- the assembly of the tank 5 is designed to facilitate maintenance of the module due to the fact that the tank can be dismantled, separated from the support for a maintenance operation, for example with a view to changing the heat transfer fluid of the thermal management module.
- the module of the present disclosure is therefore designed to group together several fluid functions of equipment such as a heat pump. According to the example, the module combines the degassing tank function and the support function for additional fluidic functions.
- the module of the present disclosure makes it possible in particular not to have to resort to additional tubing or pipes to fluidly connect different components to each other and to electrical harnesses to connect the actuators to the computer.
- the module of the present disclosure is compact, which reduces the space occupied by the assembly and its overall size.
- the module described makes it possible to reduce the bulk of all of its components, in particular of the various heat transfer fluid circuits.
- the assembly according to the invention forms a compact module which forms part of the heat pump.
- the module can include more than two pumps and more than one solenoid valve, the printed circuit carrying the controller comprising in this case additional connectors coming out of additional openings in the plate.
