[0062] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0063] In this application, battery cells may include lithium-ion secondary battery cells, lithium-ion primary battery cells, lithium-sulfur battery cells, sodium-lithium-ion battery cells, sodium-ion battery cells, or magnesium-ion battery cells, and the embodiments of this application are not limited thereto. Battery cells may be cylindrical, flat, rectangular, or in other shapes, and the embodiments of this application are not limited thereto.

[0064] The battery referred to in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery referred to in this application may include a battery module or a battery pack. A battery generally includes a casing that encloses one or more battery cells. The casing prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0065] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become a crucial component of this sustainable development. Battery technology is a crucial factor in the development of electric vehicles. As the power source of pure electric vehicles, power batteries are a key component in improving overall vehicle performance. The battery's temperature characteristics directly impact the performance, lifespan, and durability of electric vehicles. Therefore, incorporating a cooling system into the battery to control its temperature is crucial for electric vehicles.

[0066] Currently, the cooling system in the battery includes a heat exchange plate, which exchanges heat with the battery cell to maintain the stability of the battery cell's heat. However, the heat exchange effect of the heat exchange plate still needs to be improved.

[0067] During use, heat exchange plates may be subjected to excessive pressure both internally and externally. To ensure stable operation under pressure, the plates' pressure resistance needs to be improved. Currently, this is often achieved by reducing the plate's flow channel ratio, increasing plate wall thickness, and reducing the diameter of the heat exchange channel. However, this can lead to problems such as easy blockage of the heat exchange channel, excessive weight of the heat exchange plate, and insufficient heat transfer efficiency.

[0068] Based on the above problems, the present application provides a heat exchange component, which includes a heat exchange plate and a support member. A heat exchange channel is provided in the heat exchange plate. The support member is provided in the heat exchange channel, and its two ends are respectively connected to the wall of the heat exchange channel. By providing the support member in the heat exchange channel, the pressure bearing capacity of the heat exchange plate is improved, so as to improve the existing technology in which the heat exchange channel wall thickness is increased and the heat exchange channel pipe diameter is reduced in order to maintain the pressure resistance of the heat exchange component, thereby improving the problems that the heat exchange component is easy to be blocked, the heat exchange medium capacity in the heat exchange plate is low, and the weight of the heat exchange component is large, so as to improve the heat exchange effect of the heat exchange component and the reliability of the heat exchange component, and improve the energy density of the battery.

A heat exchange channel 42 is provided in the heat exchange plate 41. The support member 45 is provided in the heat exchange channel 42, and its two ends are respectively connected to the wall of the heat exchange channel 42. By providing the support member 45 in the heat exchange channel 42, the pressure bearing capacity of the heat exchange plate 41 is improved, so as to improve the existing technology in which the wall thickness of the heat exchange channel 42 is increased and the pipe diameter of the heat exchange channel 42 is reduced in order to maintain the pressure resistance of the heat exchange component 4, which leads to the problems of easy blockage of the heat exchange component 4, low heat exchange medium capacity in the heat exchange plate 41, and heavy weight of the heat exchange component 4, so as to improve the heat exchange effect of the heat exchange component 4 and the reliability of the heat exchange component 4, and improve the energy density of the battery.

[0089] Heat exchange component 4 is applied to the battery.

For example, the heat exchange plate 41 includes a plurality of heat exchange channels 42 extending along the length of the heat exchange plate 41 and spaced apart along the width of the heat exchange plate 41. Each heat exchange channel 42 is connected to a confluence structure located outside the heat exchange plate 41, so that heat exchange medium can be exchanged between the heat exchange channel 42 and the external environment through the confluence structure.

[0091] Support member 45 is disposed within heat exchange channel 42 and welded to heat exchange plate 41 to enhance the connection reliability between support member 45 and heat exchange plate 41 and improve the sealing performance of heat exchange plate 41.

Support member 45 can be made of metal or polymer.

[0092] Both ends of the support member 45 are respectively connected to the wall of the heat exchange channel 42, which means that both ends of the support member 45 are in contact and connected with the heat exchange plate 41, so that the support member 45 can play the role of supporting the heat exchange channel 42, but it is not limited to two connection points between the support member 45 and the heat exchange channel 42. One end of the support member 45 can have multiple welding points with the heat exchange plate 41, and the number of welding points at both ends of the support member 45 can be the same or different.

[0095] In these embodiments, the heat exchange channel 42 includes a main channel 421 and a branch channel 422 that are interconnected. The branch channels 422 are interconnected through the main channel 421. By arranging the support member 45 on the main channel 421 and / or the branch channel 422, so that the main channel 421 and / or the branch channel 422 maintain sufficient pressure resistance, the pipe diameter of the main channel 421 and / or the branch channel 422 is increased to improve the anti-blocking ability of the main channel 421 and / or the branch channel 422, thereby improving the heat exchange capacity of the heat exchange component 4.

[0096] The heat exchange channel 42 includes a main channel 421 and a branch channel 422, and the input end 431 and the output end 432 are both connected to the main channel 421. The heat exchange medium enters the main channel 421 from the outside, and then is distributed to each branch channel 422 through the main channel 421. Specifically, the branch channel 422 extends along the length direction of the heat exchange plate 41, and each branch channel 422 is arranged at intervals along the width direction of the heat exchange plate 41. The main channel 421 is provided at both ends of the heat exchange plate 41 in the length direction, and is respectively connected to the two ports of each branch channel 422, so that each branch channel 422 is connected through the main channel 421, so that the heat exchange medium can flow in each branch channel 422. Among them, the main channel 421 mainly plays the role of converging and transferring the heat exchange medium to each branch channel 422. The battery cell mainly contacts the branch channel 422 area for heat exchange.

[0097] The support member 45 is arranged in at least one of the main channel 421 and the branch channel 422. The support member 45 can be arranged only in the main channel 421, or only in the branch channel 422, or in both the main channel 421 and the branch channel 422.

[0098] Please refer to FIG6 , which is a schematic structural diagram of a first support member of a heat exchange component provided in an embodiment of the present application.

[0099] In some embodiments, as shown in Figures 5 and 6, the support member 45 includes a first support member 46 arranged in the main channel 421, and the first support member 46 includes a first connecting portion 461 and a second connecting portion 462 arranged opposite to each other, and the first connecting portion 461 and the second connecting portion 462 are respectively connected to the wall portion of the main channel 421.

[0100] In these embodiments, a first support member 46 is provided in the main channel 421 to improve the compressive resistance of the main channel 421; the first support member 46 includes a first connecting portion 461 and a second connecting portion 462 that are relatively arranged, and the first connecting portion 461 and the second connecting portion 462 are respectively connected to the wall portions of the main channel 421, so that the first support member 46 plays a supporting role for the main channel 421 through the first connecting portion 461 and the second connecting portion 462.

[0101] The first support member 46 includes a first connecting portion 461 and a second connecting portion 462 disposed opposite each other. The first support member 46 is welded to the heat exchange plate 41 via the first and second connecting portions 461, 462. The first support member 46 can be rod-shaped or plate-shaped. Alternatively, multiple second connecting portions 462 can be connected to the first connecting portion 461 to enhance the connection strength between the first support member 46 and the heat exchange plate 41.

[0102] Optionally, the first support member 46 extends along the first direction X to increase the contact area between the first connection portion 461 and the heat exchange plate 41, thereby improving the connection reliability between the first connection portion 461 and the heat exchange plate 41. The second connection portion 462 extends along the first direction X to increase the contact area between the second connection portion 462 and the heat exchange plate 41, thereby improving the connection reliability between the second connection portion 462 and the heat exchange plate 41. The two second connection portions 462 are arranged to extend relative to each other or opposite to each other in the first direction X.

[0103] In some embodiments, as shown in FIG. 5 and FIG. 6 , the two second connection portions 462 are respectively connected to two ends of the first connection portion 461 in the first direction X.

[0104] In these embodiments, the two second connection parts 462 are respectively connected to the two ends of the first connection part 461 in the first direction X, so as to improve the connection reliability between the first support member 46 and the heat exchange plate 41.

[0105] The second connection parts 462 are provided at both ends of the first support member 46 in the first direction X, and the first connection part 461 and the second connection part 462 are connected by a connection member extending along the thickness direction of the heat exchange plate 41. For example, the first support member 46 is n-shaped or u-shaped.

[0106] Please refer to Figures 7 and 8. Figure 7 is a partial structural diagram of a heat exchange component provided in one embodiment of the present application; Figure 8 is an enlarged structural diagram of point A in Figure 7.

[0107] In some embodiments, as shown in Figures 7 and 8, the heat exchange plate 41 includes a confluence area 411, a main channel 421 and at least two branch channels 422 are connected in the confluence area 411, and the support member 45 includes a third support member 49. At least one third support member 49 is located in the confluence area 411, and the third support member 49 extends along the first direction X. The straight line extending along the first direction X is arranged to intersect with the length direction or the width direction of the heat exchange plate 41.

[0108] In these embodiments, within the confluence area 411 of the heat exchange plate 41, a main channel 421 and at least two branch channels 422 are connected within the confluence area 411, and the main channel 421 and the branch channels 422 exchange heat exchange medium within the confluence area 411. The support member 45 includes a third support member 49, and at least one third support member 49 is located in the confluence area 411. The third support member 49 plays a role in guiding and diverting flow. The third support member 49 extends along the first direction X, and the straight line extending along the first direction X is arranged to intersect with the length direction or width direction of the heat exchange plate 41. By adjusting the setting angle of the third support member 49, the flow rate of the heat exchange medium transported from the main channel 421 to each branch channel 422 can be adjusted, so that the heat exchange component 4 has a better heat exchange effect.

[0109] Specifically, within the confluence region 411 of the heat exchange plate 41, a main channel 421 communicates with at least two branch channels 422, and the heat exchange medium is distributed from the main channel 421 to each branch channel 422. A third support member 49 within the confluence region 411 is disposed between the main channel 421 and the branch channels 422. During medium transmission, the third support member 49 serves to block and guide the heat exchange medium. Therefore, during the preparation of the heat exchange component 4, the angle of the third support member 49 can be adjusted to adjust the flow rate of the heat exchange medium distributed from the main channel 421 to each main channel 421.

[0110] The arrangement in which a straight line extending in the first direction X intersects the axis of the main channel 421 indicates that the first direction X is the extension direction of the third support member 49. By adjusting the angle between the third support member 49 and the length or width direction of the heat exchange plate 41, that is, adjusting the setting angle of the third support member 49, the third support member 49 can function to guide and divert flow. For example, when adjusting the setting angle of the third support member 49, a line extending along the length or width direction of the heat exchange plate 41 can be used as a reference line, and the angle between the extension direction of the third support member 49 and the reference line can be adjusted. The specific setting angle of the third support member 49 can be flexibly set.

[0111] One heat exchange plate 41 may include a plurality of confluence areas 411 , and the angles between the third support member 49 in each confluence area 411 and the reference line may be the same or different.

[0112] Optionally, the structure of the third support member 49 may be the same as or different from that of the first support member 46 or the second support member 47. Alternatively, the third support member may be plate-shaped, U-shaped, N-shaped, or the like.

[0113] In some embodiments, as shown in FIG. 5 and FIG. 6 , one end of the second connection portion 462 in the first direction X abuts against the wall of the main channel 421 .

[0114] In these embodiments, one end of the second connection portion 462 in the first direction X abuts against the wall of the main channel 421 , so that the first support member 46 can provide pressure to the heat exchange channel 42 in the first direction X to improve the pressure resistance of the heat exchange channel 42 .

[0115] Optionally, the two second connection parts 462 extend opposite to each other in the first direction X, one end of the second connection part 462 is connected to the second connection part 462, and the other end thereof abuts against the wall of the main channel 421, so that the first support member 46 can provide improved support for the main channel 421 in the first direction X.

[0116] In some embodiments, as shown in FIG. 5 and FIG. 6 , a plurality of first support members 46 are disposed at intervals in the main channel 421 .

[0117] In these embodiments, multiple first support members 46 are arranged at intervals in the main channel 421 to reduce the obstruction of the heat exchange medium in the main channel 421 caused by the first support members 46 arranged in the main channel 421, and reduce the preparation cost of the support members 45 and the weight of the heat exchange component 4.

[0118] Relatively speaking, the volume of the main channel 421 is smaller than that of the branch channel 422. Therefore, the first support member 46 is arranged at intervals to reduce the volume of the support member 45 in the main channel 421, so as to reduce the obstruction of the first support member 46 on the heat exchange medium in the main channel 421 and reduce the pressure drop effect of the first support member 46 on the heat exchange medium in the main channel 421.

[0119] Optionally, the plurality of first support members 46 are evenly distributed at equal intervals, so that the compression resistance of the main channel 421 is uniform throughout.

[0120] Please refer to FIG9 , which is a schematic structural diagram of a second support member of a heat exchange component provided in an embodiment of the present application.

[0121] In some embodiments, as shown in FIG. 4 and FIG. 9 , at least a portion of the support member 45 is provided with a spoiler structure 48 .

[0122] In these embodiments, the spoiler structure 48 is provided on the support member 45 so that when the heat exchange medium flows, the spoiler structure 48 destroys the laminar flow of the heat exchange medium, thereby improving the thermal conductivity of the heat exchange medium in the heat exchange channel 42 and improving the heat exchange effect of the heat exchange component 4.

[0123] For example, the spoiler structure 48 is a bump protruding from the support member 45, and / or the spoiler structure 48 is a groove recessed in the support member 45. The bump may be rectangular, semicircular, or dot-shaped, etc. The groove may be semicircular, rectangular, strip-shaped, or dot-shaped, etc.

[0124] When the heat exchange medium flows inside the heat exchange channel 42, the heat exchange medium flows in a laminar flow, which increases the heat exchange thermal resistance between the heat exchange medium and the heat exchange plate 41, resulting in poor heat exchange effect of the heat exchange component 4. Therefore, in the embodiment of the present application, a spoiler structure 48 is provided on the support member 45 so that when the heat exchange medium flows through the spoiler structure 48, the spoiler structure 48 disturbs the heat exchange medium to disrupt the laminar flow of the heat exchange medium, thereby improving the thermal conductivity of the heat exchange medium and improving the heat exchange effect of the heat exchange component 4.

[0125] In some embodiments, as shown in Figures 5 and 9, the support member 45 includes a second support member 47 arranged in the diversion channel 422, and the second support member 47 includes a main body 473, a third connecting portion 471 and a fourth connecting portion 472. The third connecting portion 471 and the fourth connecting portion 472 are respectively arranged at both ends of the main body 473, and the main body 473 is connected to the wall of the diversion channel 422 through the third connecting portion 471 and the fourth connecting portion 472.

[0126] In these embodiments, a second support member 47 is provided in the diverter channel 422 to improve the pressure resistance of the diverter channel 422. The second support member 47 includes a main body 473, a third connecting portion 471 and a fourth connecting portion 472. The third connecting portion 471 and the fourth connecting portion 472 are respectively provided at both ends of the main body 473. The main body 473 is connected to the wall of the diverter channel 422 through the third connecting portion 471 and the fourth connecting portion 472, so that the second support member 47 supports the main channel 421 through the third connecting portion 471 and the fourth connecting portion 472. The size of the second support member 47 in the first direction X is small to reduce the difficulty of matching the second support member 47 and the diverter channel 422.

[0127] Exemplarily, the second support member 47 is in the shape of a straight rod, or the second support member 47 is in a C-shape or a Z-shape.

[0128] Optionally, the third connecting portion 471 and the fourth connecting portion 472 extend along the width direction of the branch channel 422 to increase the connection area between the second support member 47 and the heat exchange plate 41, thereby improving the connection reliability between the second support member 47 and the heat exchange plate 41. Exemplarily, the third connecting portion 471 and the fourth connecting portion 472 extend in the same direction or in opposite directions.

[0129] Relatively speaking, the width of a single main channel 421 is greater than the width of a single branch channel 422. Therefore, in the width direction of the heat exchange channel 42, the width of the second support member 47 is smaller than the width direction of the first support member 46 to facilitate the assembly of the second support member 47 and the branch channel 422.

[0130] In some embodiments, as shown in FIG. 5 and FIG. 9 , at least a portion of the second support member 47 is provided with a spoiler.

[0131] In these embodiments, at least part of the second support member 47 is provided with a spoiler. The spoiler provided on the second support member 47 can destroy the laminar flow of the heat exchange medium when the heat exchange medium flows, thereby improving the thermal conductivity of the heat exchange medium in the branch channel 422 and improving the heat exchange effect of the heat exchange component 4.

[0132] It should be clear that the spoiler portion provided on the second support member 47 in this embodiment is the spoiler structure 48 in the above embodiment, and the two are substantially the same.

[0133] For example, the spoiler is a bump protruding from the second support member 47, and / or the spoiler is a groove recessed in the second support member 47. The bump may be rectangular, semicircular, or dot-shaped, etc. The groove may be semicircular, rectangular, strip-shaped, or dot-shaped, etc.

[0134] When the heat exchange medium flows inside the heat exchange channel 42, the heat exchange medium flows in a laminar flow, which increases the heat exchange thermal resistance between the heat exchange medium and the heat exchange plate 41, resulting in poor heat exchange effect of the heat exchange component 4. Therefore, in the embodiment of the present application, a spoiler is provided on the second support member 47 so that when the heat exchange medium flows through the spoiler, the spoiler disturbs the heat exchange medium to disrupt the laminar flow of the heat exchange medium, thereby improving the thermal conductivity of the heat exchange medium and improving the heat exchange effect of the heat exchange component 4.

[0135] Optionally, both the first support member 46 and the second support member 47 are provided with flow spoilers to improve the heat exchange effect of the heat exchange component 4 .

[0136] In some embodiments, as shown in FIG. 4 , FIG. 5 and FIG. 9 , the heat exchange plate 41 includes a first panel 441 for contacting the battery cell, a third connection portion 471 connected to the first panel 441 , and a spoiler protruding from the third connection portion 471 .

[0137] In these embodiments, the heat exchange plate 41 includes a first panel 441 for contacting the battery cell, a third connection portion 471 is connected to the first panel 441, and a spoiler is protruded from the third connection portion 471. The spoiler protruding from the third connection portion 471 not only plays a spoiler role, but also increases the heat exchange area at the third connection portion 471, so as to improve the heat exchange effect of the heat exchange component 4.

[0138] The heat exchange plate 41 includes a first panel 441 and a second panel 442 connected by brazing. The first panel 441 and the second panel 442 are connected to form a heat exchange channel 42 between the first panel 441 and the second panel 442. The first panel 441 of the heat exchange plate 41 contacts the battery cells. Therefore, a spoiler is provided on the third connecting portion 471 connected to the first panel 441. The protruding spoiler increases the heat exchange area of ​​the third connecting portion 471, thereby improving the heat exchange effect of the heat exchange component 4.

[0139] Optionally, both the third connecting portion 471 and the fourth connecting portion 472 are provided with spoilers, and the spoiler performance of the second supporting member 47 is improved by increasing the number of spoilers.

[0140] Please refer to FIG10 , which is an enlarged structural diagram of point B in FIG9 .

[0141] In some embodiments, as shown in Figures 9 and 10, the main body 473 is provided with a hollow area 474, the spoiler is located in the hollow area 474, the spoiler includes a fixed end and a free end, the fixed end is connected to the main body 473, and the free end is inclined along the thickness direction of the main body 473 so that the free end and the hollow area 474 are spaced apart.

[0142] In these embodiments, the main body 473 is provided with a hollow area 474, the spoiler is located in the hollow area 474, the spoiler includes a fixed end and a free end, the fixed end is connected to the main body 473, and the free end is inclined along the thickness direction of the main body 473 so that the free end and the hollow area 474 are spaced apart. The hollow area 474 of the main body 473 and the spoiler arranged in the hollow area 474 both play a spoiler role, so as to improve the heat exchange effect of the heat exchange component 4.

[0143] The body 473 is provided with a plurality of hollow areas 474. The free end of the spoiler is spaced apart from the hollow areas 474 so that both the spoiler and the hollow areas 474 of the body 473 can function as flow spoilers. Specifically, the spoiler and the body 473 are integrally formed, with the fixed end of the spoiler connected to the body 473. The free end of the spoiler extends toward one side in the thickness direction of the body 473 so that the spoiler protrudes from the surface of the body 473. The protruding spoiler functions as a flow spoiler. Because the free end of the spoiler is spaced apart from the hollow areas 474, both hollow areas 474 on both sides of the body 473 in the thickness direction can function as flow spoilers.

[0144] Optionally, the hollow areas 474 are evenly spaced so that the second support member 47 has a uniform flow disturbance effect in the extending direction thereof.

[0145] In some embodiments, as shown in FIG. 5 and FIG. 9 , the second support member 47 is continuously extended in each branch channel 422 .

[0146] In these embodiments, the second support member 47 is continuously extended in the branch channel 422 to increase the heat exchange area of ​​the heat exchange component 4 and improve the heat exchange effect of the heat exchange component 4 .

[0147] Optionally, a second support member 47 is continuously extended within a single branch channel 422 to increase the surface area of ​​the second support member 47 and the heat exchange area of ​​the branch channel 422. The continuously extended second support member 47 also increases the connection area between the second support member 47 and the heat exchange plate 41, thereby improving the connection reliability between the second support member 47 and the heat exchange plate 41.

[0148] In some embodiments, as shown in FIG4 , the heat exchange plate 41 includes two sub-plates arranged opposite to each other, the two sub-plates enclosing a heat exchange chamber, the heat exchange channel 42 is arranged in the heat exchange chamber, and the thickness L of at least one sub-plate satisfies 0.4 mm ≤ L ≤ 1.2 mm.

[0149] In these embodiments, when the thickness L of at least one sub-plate of the heat exchange plate 41 falls within the above range, the heat exchange component 4 can have sufficient structural strength while reducing its own weight, increasing the heat exchange medium capacity in the heat exchange plate 41, and improving the heat exchange effect of the heat exchange component 4.

[0150] The sub-panel in this embodiment is either the first panel 441 or the second panel 442 in the above embodiments.

[0151] For example, the thickness of the sub-plate may be 0.4 mm, 0.5 mm, 1 mm or 1.2 mm.

[0152] In some embodiments, as shown in FIG. 4 , the thickness L of the sub-plate satisfies 0.8 mm ≤ L ≤ 1.2 mm.

[0153] In these embodiments, when the thickness L of the sub-plate meets the above range, the structural strength of the heat exchange plate 41 is further improved, and the service life of the heat exchange plate 41 is increased.

[0154] For example, the thickness of the sub-plate may be 0.8 mm, 0.9 mm, 1 mm or 1.2 mm.

[0155] Optionally, the thickness of the two sub-plates is between 0.8 mm and 1.2 mm.

[0156] In some embodiments, as shown in FIG. 4 and FIG. 5 , the support member 45 is connected to the wall of the heat exchange channel 42 at both ends of the heat exchange plate 41 in the thickness direction.

[0157] In these embodiments, the heat exchange channel 42 is mainly subjected to pressure in the thickness direction during use, so the support members 45 along the thickness direction of the heat exchange plate 41 can provide better support for the heat exchange channel 42 .

[0158] Optionally, the first connection portion 461 and the second connection portion 462 are arranged opposite to each other along the thickness direction of the heat exchange plate 41 , and the third connection portion 471 and the fourth connection portion 472 are connected to both ends of the body 473 along the thickness direction of the heat exchange plate 41 .
