[0001] The present invention relates to a reinforcing plate for a thermal regulation device, in particular a cooling device, in particular for an electrical component that easily releases heat during operation, in particular for a device for cooling at least one battery or battery cell of a vehicle (such as a motor vehicle), but also for stationary installations such as computer servers or wind turbines. The vehicle can be a land vehicle, a marine vehicle or an air vehicle.

[0002] The present invention particularly relates to a plate heat exchanger for a refrigerant fluid circulation for cooling the battery of an electric or hybrid vehicle. Background Art

[0003] In order to improve the heat conduction between a heating element and a thermal regulation device during operation, a thermal paste is placed between them. When these heating elements are assembled with the thermal regulation device, this generates mechanical pressure on the thermal regulation device. It is known practice to use elastic pads to compensate for these forces. However, these elastic pads have the disadvantage of being particularly expensive because they are made especially of silicone resin. The choice of silicone resin is because its fire-resistant properties are acceptable for the intended application area. Other materials are known in the prior art, such as using EPDM (ethylene-propylene-diene monomer) or PU (polyurethane) for these elastic pads.

[0004] It is also known practice to provide plates for thicker heat exchangers. However, the disadvantage of this solution is that it increases the mass of the vehicle, thereby increasing its energy consumption. Summary of the Invention

[0026] According to one aspect of the present invention, the reinforcement plate includes a peripheral wall on at least a part of its periphery, and the peripheral wall mainly extends perpendicular to the main elongation plane of the upper plate and the lower plate. Therefore, advantageously, this wall further increases the strength of the reinforcement plate, especially with respect to mechanical torsional and bending stresses on the lower plate of the thermal regulation device.

[0034] According to one aspect of the present invention, the reinforcing plate is made of metal, preferably made of aluminum.

[0035] According to one aspect of the present invention and alternatively, the reinforcing plate can be made of a composite material. This has the advantage of providing good mechanical strength while being lighter than metal. In an example of being used in a vehicle, this makes it possible to reduce the energy consumption for the propulsion of the vehicle.

[0036] According to one aspect of the present invention, the reinforcing plate is configured to be brazed to the lower plate and the upper plate of the thermal regulation device.

[0048] According to one aspect of the invention, the channels are formed by cavities formed in the lower plate and closed by stacking with the upper plate.

[0049] According to one aspect of the invention, since the thickness of the lower plate is less than the width of the channels, the cavities forming the channels form protrusions extending outward from the side opposite to the side in contact with the upper plate.

[0050] According to one aspect of the invention, the reinforcement plate only contacts the protrusions of the lower plate.

[0051] According to one aspect of the invention, the channels extend between a common inlet and a common outlet of the heat transfer fluid.

[0067] The reinforcement plate 1 includes a first section 7 which is configured to contact a part of the lower plate 3, and this part of the lower plate 3 includes at least a part of the plurality of flow channels 4.

[0068] The reinforcement plate 1 may include a second section 8 which is configured to contact a part of the lower plate 3 that does not include any flow channels 4.

[0069] The reinforcement plate 1 includes at least one rib 9.

[0070] The rib 9 includes a main extension direction which is arranged in the plane of the reinforcement plate 1 and in a direction intersecting the main orientation of the plurality of flow channels 4 in the part of the lower plate 3 where the reinforcement plate (1) is arranged, preferably perpendicular to the main orientation of the flow channels 4 in the part of the lower plate 3 where the reinforcement plate 1 is arranged. Therefore, it should be understood that the main orientation of the channels 4 is the orientation of the channels 4 configured to face the first section 7 of the reinforcement plate 1, and the first section 7 includes at least one rib 9. The main orientation of the plurality of channels must be understood as the orientation of the maximum dimension along which the channels 4 extend. Therefore, in Figure 1 and Figure 2 example, the ribs 9 of the reinforcement plate 1 extend perpendicular to the channels 4 placed below these ribs 9. In Figure 1 and Figure 2 , the channels 4 mainly extend along the length of the lower plate 3, so the ribs 9 mainly extend in a direction arranged across the width of the lower plate 3.

[0071] Alternatively, the rib 9 is arranged parallel to the plurality of flow channels 4 in the part of the lower plate 3 where the reinforcement plate 1 is arranged.

[0072] The reinforcement plate 1 includes an upper surface 10 configured to contact the at least one part of the lower plate 3, and the rib 9 is formed by a cavity that extends from the upper surface 10 of the reinforcement plate 1 and is perpendicular to the lower plate 3 of the thermal regulation device 100. Advantageously, the rib 9 can be obtained by stamping the reinforcement plate 1, so the reinforcement plate 1 enables the optimization of the amount of material required to obtain the component while maintaining the robustness provided by the rib 9.

[0073] The cavity may include a heat insulation part.

[0074] It should also be understood that the rib 9 can be obtained by extruding or molding the reinforcement plate 1. The rib 9 can be integrally formed and have no cavity, in other words, in the cross-sectional view of the reinforcement plate 1, the rib 9 is solid.

[0075] The reinforcement plate 1 includes a plurality of ribs 9 as described above.

[0076] The plurality of ribs 9 includes ribs 9 having different sizes. For example, at least one rib 9 having a different size from the other ribs 9 may be arranged on the periphery of the reinforcement plate 1, or alternatively, the at least one rib 9 having different sizes may be arranged at the center of the reinforcement plate 1.

[0077] The plurality of ribs 9 includes a set of straight segments 90 parallel to each other. It should be understood that these straight segments 90 define the main elongation direction of the ribs 9.

[0078] The plurality of ribs 9 includes U-shaped segments 91 connecting adjacent straight segments 90.

[0079] Alternatively, the U-shaped segments 91 may be replaced by straight segments or V-shaped segments.

[0080] The plurality of ribs 9 includes at least two sets of ribs 9, each set of ribs 9 being configured to be arranged facing different parts of the plurality of channels 4; this is not shown in the drawings.

[0081] Each set of ribs 9 is configured to be arranged on a part of the plurality of channels 4 having a main extension direction different from that of another part.

[0082] One of the sets of ribs includes at least two ribs 9, each rib being arranged on at least one side of the other set of ribs, and the ribs 9 arranged on the sides may have different sizes from the ribs 9 of the adjacent set, preferably larger sizes.

Thus, and advantageously, this wall 10 further increases the strength of the reinforcement plate 1, especially with respect to mechanical torsional and bending stresses on the lower plate 3 of the thermal regulation device 100.

[0084] The wall 10 is integrally formed with the reinforcement plate 1, preferably obtained by stamping.

[0085] According to Figure 1 In the first embodiment of the present invention shown, a single reinforcement plate is arranged on the thermal regulation device. The reinforcement plate 1 covers 25% of the lower plate 3, preferably covers 50% of the lower plate 3, and even more preferably covers the entire surface of the lower plate 3.

[0086] As Figure 2 shown, according to the second embodiment of the present invention, the present invention also relates to a strengthening device 200, which includes a plurality of reinforcement plates 1, such as the reinforcement plates 1 described above, and is configured to be attached to the same lower plate 3 of the thermal regulation device 100.

[0087] Each plate 1 includes at least one rib 9 as described above.

[0088] Each reinforcing plate 1 includes at least one rib 9 oriented in a direction different from that of the rib 9 of the other plate 1.

[0089] The reinforcing plate 1 preferably has the same shape as the lower plate 3, but alternatively, it may have a shape different from that of the lower plate 3. Thus, it should be understood that when the lower plate 3 has a substantially flat shape, the reinforcing plate 1 is preferably flat.

[0090] The reinforcing plate 1 can be, for example, a quadrilateral or a T-shaped polygon.

[0091] The reinforcing plate 1 is made of metal, preferably made of aluminum. Different from the elastic pads of the prior art, metal has the advantage of being non-flammable. In addition, it is also superior in terms of wear resistance and recyclability.

[0092] Alternatively, the reinforcing plate 1 can also be composed of a composite material. This has the advantage of providing good mechanical strength while being lighter than metal. In the example of being used in a vehicle, this makes it possible to reduce the energy consumption for vehicle propulsion.

[0093] The reinforcing plate 1 is brazed to the lower plate 3 and the upper plate 2 of the thermal regulation device 100.

[0094] Alternatively, the reinforcing plate 1 can be laser welded to the lower plate 3 of the thermal regulation device 100.

[0095] Again alternatively, the reinforcing plate 1 can be riveted to the lower plate 3 of the thermal regulation device 100.

[0096] The reinforcing plate 1 can also be adhered to the lower plate 3 of the thermal regulation device 100.

[0097] The thickness of the reinforcing plate 1 is in the range of 0.5 mm to 1.3 mm.

[0098] The thermal regulation device 100 can include a space for receiving the components to be cooled, particularly battery cells. The module 300 can also include a plurality of reinforcing plates 1, and each reinforcing plate 1 is arranged facing a space.

[0099] Each of the lower plate 3 and the upper plate 2 has a thickness of at most 3 mm, and more typically a thickness between 0.8 mm and 1.3 mm.

[0100] The heat transfer fluid can particularly be a refrigerant fluid, especially a fluid selected from refrigerant fluids R134a, R1234yf, and R744, or an ethylene glycol / water mixture.

[0101] The plurality of channels 4 can mainly include straight or curved channels.

[0102] The plurality of channels 4 may include straight sections connected to the curved section.

[0103] The plurality of channels 4 in the lower plate 3 of the thermal regulation device 100 are preferably formed by stamping.

[0104] The channels 4 extend from one side of the lower plate 3 in contact with one side of the upper plate 2 in a direction opposite to that side.

[0105] The channels 4 are formed by cavities formed in the lower plate 3 and are closed by stacking with the upper plate 2.

[0106] Since the thickness of the lower plate 3 is less than the width of the channels 4, the cavities forming the channels 4 form protrusions extending outward from the side opposite to the side in contact with the upper plate 2.

[0107] The reinforcing plate 1 only contacts the protrusions of the lower plate 3.

[0108] The channels 4 extend between a common inlet and a common outlet for the heat transfer fluid.

[0109] Flanges may be connected to the inlet and outlet to provide the connection.
