Description

Technical Field

[0001] The present invention relates to a thermal regulation device for cooling and / or heating at least one operating temperature-sensitive component, particularly the power electronics module or battery cell of an inverter. Background Technology

[0002] In the context of electrification in the automotive industry, many electronic components have been developed or improved to accommodate higher power and higher duty cycles. Typically, the quality of thermal management of the electronic devices used is affected because they have operating temperature limitations. Therefore, optimizing the cooling of these electronic components is crucial to improving durability or reducing the costs associated with them. These electronic components can be, for example, parts of a vehicle's motor, parts of a DC-DC converter, on-board chargers, inverters, etc.

[0003] For some of these components, the heat flux generated by these components is very high due to their small surface area (very small components). It is also required that the uniformity of temperature be highest among the several heat sources that constitute the components.

[0004] In some configurations, these components are arranged in series. For example, the motor and associated inverter are arranged in series to optimize compactness (or packaging), but this arrangement imposes temperature and minimum flow rate limitations on the heat transfer fluid used to cool these components.

[0005] Components to be cooled include, for example, the switching unit modules of an inverter. These types of components are temperature-sensitive and require precise thermal management. Currently, thermal devices with copper base plates allow for this thermal management, featuring cooling elements in the form of machined pins immersed in a coolant flow. In these devices, the temperature is non-uniform because the pins are always arranged identically along the plate, thus imposing a constant heat transfer coefficient. Due to the natural heating of the fluid along the plate, the heat exchange capacity is reduced, resulting in a non-uniform temperature distribution at the components. Summary of the Invention

[0006] The present invention is particularly aimed at further improving the thermal regulation of components, especially for cooling them, by proposing solutions that are thermally efficient and have simpler designs and / or lower manufacturing costs.

[0007] Therefore, the present invention relates to a thermal regulation device for cooling and / or heating at least one operationally temperature-sensitive component, particularly a power electronic module or battery cell of an inverter, the thermal regulation device comprising a stack of at least three plates, the at least three plates being brazed together, a heat transfer fluid circuit being disposed within the stack, the thermal regulation device having an outer surface on which one or more components, such as a power electronic module, may be placed, the heat transfer fluid circuit comprising at least:

[0008] - A first heat transfer fluid circulation section, wherein the first heat transfer fluid circulation section is provided with a first fluid flow turbulence element, the first fluid flow turbulence element being configured to promote heat transfer of the heat transfer fluid in the first section within a first flow rate range, and

[0009] - A second heat transfer fluid circulation section, wherein the second heat transfer fluid circulation section is provided with a second fluid flow turbulence element, the second fluid flow turbulence element being used to promote heat transfer of the heat transfer fluid in the second section within a second flow range.

[0010] - and the second turbulence element (20) is configured to generate a smaller pressure drop than that generated by the first turbulence element (18), and the first portion and the second portion are in fluid communication.

[0011] The advantage of this invention is that it can provide satisfactory thermal performance for different flow rates of the heat transfer fluid used during the operation of the thermal conditioning device.

[0012] In other words, the present invention enables good thermal performance to be maintained over a wide flow range of the heat transfer fluid.

[0013] Specifically, the first circulation portion having its first turbulence element enables good thermal performance within a first flow range, while the second circulation portion having its second turbulence element enables good thermal performance within a second flow range.

[0014] By selecting two flow ranges that maintain good thermal performance over the entire range that is the sum of the first and second flow ranges, the present invention enables good thermal performance for various operating modes that the thermal regulation device may encounter.

[0015] This is particularly advantageous when the fluid flow rate through the thermal conditioning device is applied, for example, by an electric motor to be cooled connected in series with the thermal conditioning device.

[0016] Preferably, a single heat transfer fluid circulates within the thermal conditioning device. The thermal conditioning device is a single-fluid type, rather than a two-fluid type.

[0017] Therefore, the same fluid circulation exists in all stages formed by the stacking of plates.

[0018] According to one aspect of the invention, the first flow range and the second flow range overlap, such that within the overlapping flow range, the thermal performance provided by the first turbulence element is substantially similar to the thermal performance achievable by the second turbulence element.

[0019] In one variation, the first and second flow-disrupting elements are configured such that the first flow range is separated from the second flow range.

[0020] In this case, there may be an intermediate range between the first and second flow ranges, in which the thermal performance is reduced compared to that provided in the first and second flow ranges.

[0021] According to one aspect of the invention, the fluid circuit includes at least a first heat transfer fluid circulation stage and a second heat transfer fluid circulation stage, the first heat transfer fluid circulation stage and the second heat transfer fluid circulation stage being substantially parallel to an outer surface, and the first heat transfer fluid circulation stage being disposed between the outer surface and the second heat transfer fluid circulation stage.

[0022] According to one aspect of the invention, the first portion extends over a first heat transfer fluid circulation stage, and the first turbulence element is configured to facilitate heat transfer within a first flow range, which is lower than a second flow range.

[0023] The phrase "the first flow range is lower than the second flow range" means that at least some flow values ​​within the first flow range are lower than the minimum flow value of the second flow range. It should be noted that the first and second flows can overlap or be separated by an intermediate range.

[0024] Therefore, the first stage enables thermal performance at lower flow rates, while the second stage enables thermal performance at higher flow rates than the first stage.

[0025] According to one aspect of the invention, the fluid circulates in parallel between the two stages, particularly in a direction perpendicular to the main longitudinal extension direction of each plate of the device.

[0026] Parallel fluid circulation between stages is superior to series circulation between stages because the fluid is balanced according to the flow rate, and performance is optimized by both types of turbulent flowmeters.

[0027] In one variation, the opposite operation can be performed, i.e., the first portion extends over the first heat transfer fluid circulation stage, and the first turbulence element is configured to facilitate heat transfer within a first flow range that is greater than the second flow range.

[0028] According to one aspect of the invention, the first turbulence element in the first portion (i.e., the portion having a lower flow range) includes fins through which heat transfer fluid flows.

[0029] According to one aspect of the invention, fins, particularly louvered fins, are formed on a corrugated structure having flanks forming the fins.

[0030] According to one aspect of the invention, the corrugated structure comprises a series of identical corrugations, which are spaced apart from each other at regular intervals.

[0031] In one variation, the corrugations of the corrugated structure can be spaced apart at a certain interval, which can vary between at least some of the corrugations.

[0032] According to one aspect of the invention, the corrugations may optionally have circular apexes and circular valleys.

[0033] According to one aspect of the invention, all the corrugations are parallel to each other.

[0034] According to one aspect of the invention, the corrugations extend over the entire first stage.

[0035] According to one aspect of the invention, a first stage or a second stage includes a fluid supply chamber and a fluid outlet chamber in communication with the stage, and fluid flows through the first stage between the fluid inlet chamber and the fluid outlet chamber.

[0036] According to one aspect of the invention, the fluid outlet chamber is arranged on the opposite side of the fluid inlet chamber, particularly on the longitudinal edge of the plate forming the stage.

[0037] According to one aspect of the invention, the fluid circuit includes a heat transfer fluid distribution stage and / or a heat transfer fluid collection stage, the heat transfer fluid distribution stage and / or the heat transfer fluid collection stage being configured to distribute fluid to a fluid circulation stage and / or collect fluid from the fluid circulation stage.

[0038] According to one aspect of the invention, the corrugations of the corrugated structure extend from the inlet chamber to the outlet chamber.

[0039] In other words, the top and bottom lines of the corrugated structure are essentially perpendicular to the fluid inlet chamber and the fluid outlet chamber.

[0040] According to one aspect of the invention, the corrugated structure is made of a metal plate, particularly an aluminum plate.

[0041] According to one aspect of the invention, the sheet has been formed to obtain a corrugated shape, for example, using a forming machine.

[0042] Corrugations can be formed by rollers or drums (mechanical forming rollers).

[0043] According to one aspect of the invention, the fin includes louvers that provide transverse fluid channels through the fin, thereby allowing fluid through the louver channels to be distributed to spaces on either side of the louvers.

[0044] This allows for a fluid distribution that is conducive to good thermal performance, as the louvers act as fluid flow disruptors.

[0045] According to one aspect of the invention, the height of the corrugated structure is equal to the height of the first portion, such that the fins contact the two opposing surfaces of the first portion. Instead of louvered or corrugated structures, the fins can also be straight in the flow direction.

[0046] The corrugated structure is part of the stack of plates.

[0047] According to one aspect of the invention, the second portion extends over the second heat transfer fluid circulation stage, and the second turbulence element is configured to facilitate heat transfer over a second flow range greater than the first flow range.

[0048] According to one aspect of the invention, the second turbulence element includes a shape present on the wall of the second portion.

[0049] According to one aspect of the invention, the height of these shapes is lower than the height of the second part.

[0050] According to one aspect of the invention, the second turbulence element is referred to as a "dimple".

[0051] According to one aspect of the invention, the second turbulence element (or "recess") is adapted to produce a smaller pressure drop than the fins of the corrugated structure, and this allows for compensation of the lower cooling efficiency in contact with these second turbulence elements. The invention enables more compact and lighter thermal regulation devices, provided that the corrugated structure can replace the thicker plates used in known constructions.

[0052] According to one aspect of the invention, each of the second perturbation elements has a free vertex, for example, at half of the second portion.

[0053] According to one aspect of the invention, the top end of the second turbulence element may be circular.

[0054] According to one aspect of the invention, the base of at least one second perturbation element has a circular, oblong, or polygonal (e.g., hexagonal) perimeter.

[0055] According to one aspect of the invention, at least some of the second spoiler elements are formed in a herringbone shape, that is, two of these second spoiler elements are arranged in such a way that they generally form two branches in a V shape.

[0056] According to one aspect of the invention, the two branches of the V-shape may be in contact with each other or separated by a certain distance.

[0057] According to one aspect of the invention, the second turbulence element is an embossed shape of a plate, particularly an aluminum plate.

[0058] According to one aspect of the invention, the stack of plates includes an intermediate plate between a corrugated structure and a plate carrying a second flow-dispersing element, for example, the intermediate plate is a planar distribution plate provided with fluid inlet holes and fluid outlet holes.

[0059] According to one aspect of the invention, the stacked plate includes an intermediate plate between the corrugated structure and the plate carrying the second flow-disrupting element. For example, the intermediate plate is a planar distribution plate provided with fluid inlet and fluid outlet orifices. In a variation, the intermediate plate is a pressed plate whose embossed shape defines the second flow-disrupting element (e.g., a "dimple").

[0060] According to one aspect of the invention, the fluid inlet and fluid outlet are located in the collection chamber.

[0061] According to one aspect of the invention, the final fluid portion (e.g., the fluid portion receiving the corrugated structure) contacts a cover plate, the outer surface of which is formed with an area for placing the component to be cooled.

[0062] According to one aspect of the invention, the thermal regulation device includes a manifold base having at least one fluid inlet and a fluid outlet for connection to an external conduit.

[0063] According to one aspect of the invention, the manifold base includes a distribution channel supplied by a fluid inlet and a discharge channel connected to a fluid outlet.

[0064] According to one aspect of the invention, the dispensing channel and the dispensing channel each have a substantially triangular shape and are particularly symmetrical to each other via an axis of symmetry extending along the diagonal of the base of the manifold.

[0065] According to one aspect of the invention, the height of the first part is greater than the height of the second part, in particular at least two times or even three times greater.

[0066] According to one aspect of the invention, the height is measured in the stacking direction of the plates, and is therefore generally perpendicular to the plane of the plates.

[0067] According to one aspect of the invention, the height of the first portion is between 4 mm and 5 mm, particularly 4.5 mm. The spacing between the corrugations can be 1.25 mm. The material thickness at the corrugations is, for example, about 0.1 mm.

[0068] According to one aspect of the invention, the height of the second portion is between 0.5 mm and 1.5 mm, particularly 1 mm. The height of the second perturbation element is approximately 0.35 mm. Attached Figure Description

[0076] The features, variations, and various embodiments of the present invention can be combined with each other in various combinations, provided that they are not incompatible or mutually exclusive. In particular, variations of the invention may be contemplated that include only selections of the features described below, isolated from the other features described, if such selections are sufficient to provide a technical advantage and / or distinguish the invention from the prior art.

[0077] Figure 1 and Figure 2 A thermal regulation device 1 is shown for cooling and / or heating a component 2 that is sensitive to temperature during operation.

[0078] like Figure 2 As shown, the thermal regulation device 1 forms part of an assembly 100, which includes electronic components 2 placed on the outer surface 10 of the thermal regulation device 1 for cooling via fluid paths within the thermal regulation device 1. These components 2 are, in particular, the power electronics modules or battery cells of an inverter.

[0079] The heat regulation device 1 includes a manifold base 4 forming a base for the heat regulation device 1, the manifold base 4 having a longitudinal shape in the direction X. From Figure 4 As can be seen, the manifold base 4 includes a fluid inlet hole 5 and a fluid outlet hole 6, which are configured to connect to an external fluid inlet pipe 8 and an external fluid outlet pipe, respectively. The fluid inlet hole 5 and the fluid outlet hole 6 are arranged at two opposite ends along the axis X of the manifold base 4.

[0080] In the described example, the thermal conditioning device 1 includes stacked plates 14 brazed together, with a heat transfer fluid loop 15 disposed within the stack. The assembly has a generally rectangular perimeter.

[0081] The stack of plates 14 also includes a manifold base 4, which thus forms the lower plate of the stack, through which a fluid connection is formed.

[0082] The manifold base 4 includes a distribution channel 41 supplied by the fluid inlet 5 and a discharge channel 42 connected to the fluid outlet 6.

[0083] Here, the dispensing channel 41 and the dispensing channel 42 each have a substantially triangular shape and are particularly symmetrical to each other via an axis of symmetry that extends along the diagonal of the manifold base 4, which has a substantially rectangular shape.

[0084] The cover plate 40 encloses the stack of plates and defines the outer surface 10.

[0085] Plate 14, cover plate 40 and manifold base 14 are made of metal (e.g., aluminum).

[0086] The heat transfer fluid circuit 15 includes at least:

[0087] - A first heat transfer fluid circulation section 17, wherein the first heat transfer fluid circulation section is provided with a first fluid flow turbulence element 18, the first fluid flow turbulence element being configured to promote heat transfer of the heat transfer fluid in the first section 17 within a first flow rate range, and

[0088] - The second heat transfer fluid circulation section 19 is provided with a second fluid flow disturbance element 20 to promote heat transfer of the heat transfer fluid in the second section 19 within a second flow range.

[0089] The second turbulence element 20 is configured to produce a smaller pressure drop than that produced by the first turbulence element 18, and the first portion 17 and the second portion 19 are in fluid communication.

[0090] A single heat transfer fluid circulates in the thermal conditioning unit 1. The thermal conditioning unit 1 is a single-fluid type, not a two-fluid type.

[0091] The first flow range and the second flow range overlap, such that within the overlapping flow range, the thermal performance provided by the first turbulence element 18 is substantially similar to the thermal performance achievable by the second turbulence element 20.

[0092] In one variation, the first and second flow-disrupting elements 18 and 20 are configured to separate the first flow range from the second flow range.

[0093] In this case, there may be an intermediate range between the first and second flow ranges, in which the thermal performance is reduced compared to that provided in the first and second flow ranges.

[0094] The fluid circuit 15 includes at least a first heat transfer fluid circulation stage E1 and a second heat transfer fluid circulation stage E2, which are substantially parallel to the outer surface 10, and the first heat transfer fluid circulation stage E1 is disposed between the outer surface 10 and the second heat transfer fluid circulation stage E2.

[0095] As in Figure 3 As can be seen, the first portion 17 extends over the first heat transfer fluid circulation stage E1, and the first turbulence element 18 is configured to facilitate heat transfer in a first flow range that is lower than the second flow range.

[0096] The phrase "the first flow range is lower than the second flow range" means that at least some flow values ​​within the first flow range are lower than the minimum flow value of the second flow range. It should be noted that the first and second flows can overlap or be separated by an intermediate range.

[0097] Therefore, the first stage E1 enables thermal performance at lower flow rates, while the second stage E2 enables thermal performance at higher flow rates than the first stage.

[0098] The fluid circulates in parallel between the two stages E1 and E2, preferably in the same flow direction F.

[0099] The first turbulence element 18 in the first part 17 (i.e. the part with lower flow rate) includes fins 21 through which heat transfer fluid flows.

[0100] The fin 21 is louvered and formed on, for example, a single-piece corrugated structure 22, which has flanks forming the fin 21.

[0101] The corrugated structure 22 comprises a series of identical corrugations spaced apart from each other at regular intervals, such as... Figure 3 and Figure 6 As shown.

[0102] In one variation, the corrugations of the corrugated structure can be spaced apart at a certain interval, which can vary between at least some of the corrugations.

[0103] The wavy alternative features circular vertices 23 and circular valleys 24.

[0104] The corrugated structure 22 extends over the entire first stage E1.

[0105] The first stage E1 is connected to the fluid supply chamber 26 and the fluid outlet chamber 27, and fluid flows through the first stage between the fluid inlet chamber and the fluid outlet chamber.

[0106] These chambers 26 and 27 define the lateral manifold.

[0107] The fluid outlet chamber 27 is located on the opposite side of the fluid inlet chamber 26.

[0108] The corrugations of the corrugated structure 22 extend from the inlet chamber 26 to the outlet chamber 27.

[0109] In other words, the top and bottom lines of the corrugated structure 22 are substantially perpendicular to the fluid inlet chamber 26 and the fluid outlet chamber 27.

[0110] The corrugated structure 22 is made of a metal sheet, particularly an aluminum sheet. For example, a forming machine is used to shape the sheet to obtain the corrugated shape. The corrugations can be formed by rollers or rolls (mechanical forming rollers).

[0111] The fin 21 includes louvers that provide transverse fluid channels through the fin, thereby allowing fluid through the louver channels to be distributed into the spaces on both sides of the louvers.

[0112] The height of the corrugated structure 22 is equal to the height of the first part 17, so that the fin 21 contacts the two opposite surfaces of the first part 17. Instead of louvered and corrugated types, the fins can also be straight in the flow direction.

[0113] The second perturbation element 20 includes a shape present on the wall 29 of the second part 19.

[0114] The height of these shapes 20 is lower than the height of the second part 19. The second turbulence element 20 is referred to as a "recess" and is adapted to produce a smaller pressure drop than the fins of the corrugated structure 22, which makes it possible to compensate for the lower cooling efficiency in contact with these second turbulence elements 20.

[0115] Each of the second perturbation elements 20 has a free vertex, for example, at half of the second part 19.

[0116] The vertex of the second perturbation element 20 can be circular.

[0117] The base of the second spoiler element 20 has a circular, oblong, or polygonal (e.g., hexagonal) perimeter.

[0118] In the described example, the second spoiler element 20 is formed in a herringbone shape, that is, the two elements of these second spoiler elements are arranged in such a way that they generally form two branches in a V shape.

[0119] The two branches of the V-shape can touch each other or be a certain distance apart.

[0120] The second turbulence element 20 is the embossed shape of plate 14.

[0121] The stack of plates 14 includes an intermediate plate 31 between the corrugated structure 22 and the plate 14 carrying the second flow-deflecting element 20. Here, the intermediate plate 31 is a planar distribution plate, which is provided with a fluid inlet hole 32 and a fluid outlet hole 33, as shown below. Figure 2 As shown. These fluid inlet holes 32 and fluid outlet holes 33 are located in the fluid supply chamber 26 and fluid outlet chamber 27.

[0122] The corrugated structure 22 contacts the cover plate 40.

[0123] The height of the first part 17 is greater than the height of the second part 19, in particular at least two or even three times larger.

[0124] The height is measured in the Z direction of the board stacking, and is therefore usually perpendicular to the plane of board 14.

[0125] The height of the first section 17 is between 4 mm and 5 mm, particularly 4.5 mm. The spacing between the corrugations can be 1.25 mm. The material thickness at the corrugations is, for example, approximately 0.1 mm.

[0126] The height of the second part 19 is between 0.5 mm and 1.5 mm, particularly 1 mm. The height of the second spoiler element is approximately 0.35 mm.
