It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0035] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0037] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0038] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] According to one embodiment of the present application, a heat exchange component is provided. Figures 1 to 5 As shown, the heat exchange assembly includes: a heat exchange body 1 and a plurality of reinforcing plates 2. The heat exchange body 1 is suitable for filling a heat exchange medium. Along a first direction of the heat exchange body 1, the plurality of reinforcing plates 2 are respectively arranged in the middle of the heat exchange body 1 and on both sides of the middle.

[0040] In this example, the heat exchange assembly includes a heat exchange body 1 and a reinforcing plate 2 disposed on the heat exchange body 1. Along the first direction of the heat exchange body 1, a plurality of reinforcing plates 2 are respectively disposed in the middle and both sides of the middle of the heat exchange body 1, thereby improving the strength of the heat exchange body 1. In addition, by arranging a plurality of reinforcing plates 2 at intervals on the heat exchange body 1, the weight added to the heat exchange assembly can also be minimized.

[0041] In this example, the first direction of the heat exchange body 1 can be the length direction or width direction of the main heat dissipation surface of the heat exchange body 1, and adjacent reinforcing plates 2 are spaced apart, and the gaps between adjacent reinforcing plates 2 can expose the heat exchange body 1, thereby improving the heat exchange effect.

[0042] like Figure 1 As shown, in this example, three reinforcing plates 2 can be provided. The three reinforcing plates 2 are arranged at intervals, and the three reinforcing plates 2 are respectively arranged at both ends and the middle position of the heat exchange body 1, so as to improve the strength of the heat exchange body 1 and minimize the weight of the heat exchange assembly as a whole.

[0043] Alternatively, more reinforcing plates 2 may be provided, for example, two or three reinforcing plates 2 may be provided in the middle of the heat exchange body 1. The multiple reinforcing plates 2 in the middle may be provided at intervals, or may be provided adjacently and in contact. Alternatively, multiple reinforcing plates 2 may be provided on both sides of the heat exchange body 1 along the length direction. Of course, the specific number of reinforcing plates 2 may be determined by those skilled in the art according to actual conditions. For example, the specific position and number of reinforcing plates 2 may be determined according to the stress points of the heat exchange body 1, and no specific limitation is made here.

[0044] like Figure 1 and Figure 6 As shown, in this example, the heat exchange body 1 has a flow channel, and the flow channel is suitable for flowing a heat exchange medium to perform heat exchange with the device to be heat exchanged. For example, the heat exchange component can be a part of a battery pack, and the device to be heat exchanged is the battery module 10. The side of the heat exchange body 1 facing away from the reinforcing plate 2 corresponds to the battery module 10 in the battery pack, and can cool or heat the battery module 10.

[0045] For example, the heat exchange medium can be a coolant, etc. The heat exchange body 1 is connected to a joint 7, through which the flow channel in the heat exchange body 1 can be connected to the external pipe body for conveying the coolant, and the flow channel can form a loop with the external pipe body, and the coolant flows in the flow channel to improve the cooling effect. Among them, the joint 7 can be made of aluminum alloy material or other metal materials. For example, the material of the joint 7 can be 3 series or 6 series aluminum alloy material, etc. Those skilled in the art can determine according to the actual situation, and no specific limitation is made here.

[0046] Alternatively, the heat exchange medium may also be a heating fluid to heat the battery module 10. Alternatively, the heat exchange medium may also be a phase change material, etc. Those skilled in the art may determine the method according to actual conditions, and no specific limitation is made here.

[0047] In this example, the reinforcing plate 2 is welded or glued to the heat exchange body 1. For example, the reinforcing plate 2 can be made of metal material, and the reinforcing plate 2 can be connected to one side of the heat exchange body 1 by welding. The reinforcing plate 2 can be made of aluminum alloy material or other metal materials. For example, it can be 4343 aluminum alloy, 4045 aluminum alloy, 3003 aluminum alloy or 3003mod aluminum plate, or 3003 composite 6 series aluminum alloy or composite 4 series aluminum alloy, or other types of composite materials, or steel-aluminum composite materials. The reinforcing plate 2 and the heat exchange body 1 can be connected by brazing and matched by tooling, or can be achieved by arc welding, stir friction welding or laser welding. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0048] Alternatively, the reinforcing plate 2 may also be a non-metallic material with relatively high strength, and the reinforcing plate 2 may be fixedly connected to one side of the heat exchange body 1 by means of adhesive bonding. Of course, the specific material of the reinforcing plate 2 may be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0049] In this example, the thickness of the reinforcing plate 2 is greater than or equal to 2 mm. The thickness direction of the reinforcing plate 2 is consistent with the thickness direction of the heat exchange body 1. The thickness of the reinforcing plate 2 is greater than or equal to 2 mm, so that the reinforcing plate 2 has good strength performance to meet the demand for improving the strength of the heat exchange body 1. For example, the thickness of the reinforcing plate 2 can be 2 mm, 2.5 mm, 3 mm or 4 mm, etc., and those skilled in the art can determine it according to actual conditions, and no specific limitation is made here.

[0050] like Figure 1 and Figure 2As shown, in this example, a plurality of reinforcing plates 2 are arranged at intervals on one side of the heat exchange body 1 along the thickness direction. The surface of the heat exchange body 1 provided with the reinforcing plates 2 is in a rectangular structure. The side of the reinforcing plate 2 parallel to the long side of the heat exchange body 1 is assumed to be the width side, the side of the reinforcing plate 2 parallel to the short side of the heat exchange body 1 is assumed to be the length side, and the length of the reinforcing plate 2 is equal to or slightly less than the length of the short side of the heat exchange body 1, and the width of the reinforcing plate 2 is 100 mm to 2500 mm, so as to meet the requirement of improving the strength of the heat exchange body 1.

[0051] The width of the reinforcing plate 2 may be 100 mm, 200 mm, 700 mm, 1500 mm, 2000 mm or 2500 mm, etc. Those skilled in the art may determine the width according to actual conditions, for example, the width of the reinforcing plate 2 may be determined according to the overall length of the heat exchange body 1, and no specific limitation is made here.

[0052] In an example, Figures 1 to 6 As shown, the plurality of reinforcing plates 2 are located on one side of the heat exchange body 1 in the thickness direction, so that the side of the heat exchange body 1 facing away from the reinforcing plates 2 is connected to the device to be heat exchanged.

[0053] like Figures 1 to 6 As shown, in this example, a plurality of reinforcing plates 2 are arranged on one side of the heat exchange body 1 along the thickness direction, and the side of the heat exchange body 1 away from the reinforcing plate 2 is suitable for connecting with the device to be heat exchanged. For example, the side of the heat exchange body 1 away from the reinforcing plate 2 can be connected to the tray 8 of the battery pack, and the tray 8 can be used to carry the battery module 10. Alternatively, the side of the heat exchange body 1 away from the reinforcing plate 2 can be connected to the sealing cover 9, and the sealing cover 9 is suitable for sealing the battery module 10.

[0054] In an example, Figure 4 and Figure 5 As shown, the reinforcing plate 2 has a hollow structure. By setting the reinforcing plate 2 as a hollow structure, the weight of the reinforcing plate 2 can be reduced, thereby further reducing the weight of the entire heat exchange assembly.

[0055] like Figures 2 to 5 As shown, the reinforcing plate 2 has a cavity 21 inside, so that the reinforcing plate 2 has a hollow structure. For example, the reinforcing plate 2 can be provided with through holes along the length or width direction, and the through holes can form a hollow structure.

[0056] In this example, if Figure 4 and Figure 5 As shown, the reinforcing plate 2 has at least one cavity 21. The reinforcing plate 2 is provided with the cavity 21 so that the reinforcing plate 2 has a hollow structure. The reinforcing plate 2 may be provided with one or more cavities 21 along the length direction. When multiple cavities 21 are provided, two adjacent cavities 21 are separated by the support plate 3, so that the strength of the reinforcing plate 2 can be improved.

[0057] In an example, Figures 1 to 5 As shown, the heat exchange body 1 includes a first plate 11 and a second plate 12, the first plate 11 is located on one side of the second plate 12 along the second direction, a first flow channel 13 is formed between the second plate 12 and the first plate 11, and a plurality of reinforcing plates 2 are connected to the side of the second plate 12 away from the first plate 11 at intervals. The first flow channel 13 is used to fill the heat exchange medium. The side of the first plate 11 away from the second plate 12 corresponds to the device to be heat exchanged.

[0058] like Figure 4 and Figure 5 As shown, in this example, the second direction can be the thickness direction of the heat exchange body 1. The first plate 11 is located on one side of the second plate 12 along the second direction, that is, the first plate 11 and the second plate 12 are stacked, and a first flow channel 13 is provided between the first plate 11 and the second plate 12. The first flow channel 13 is suitable for filling a heat exchange medium, wherein the heat exchange medium can be a refrigerant or a heating fluid, etc. The side of the first plate 11 away from the second plate 12 can correspond to the device to be heat exchanged, and the heat exchange medium can exchange heat with the device to be exchanged through the first plate 11.

[0059] like Figure 4 and Figure 5 As shown, the reinforcing plate 2 is connected to the side of the second plate 12 away from the first plate 11, which can improve the strength of the second plate 12, thereby improving the strength of the heat exchange body 1. The second plate 12 is provided with a plurality of reinforcing plates 2, and the plurality of reinforcing plates 2 are respectively arranged at both ends and the middle of the second plate 12. That is, the plurality of reinforcing plates 2 are arranged at intervals on the second plate 12, thereby improving the strength of the second plate 12 and reducing the weight of the heat exchange body 1 as much as possible.

[0060] In this example, the second plate 12 is provided with a plurality of grooves toward the first plate 11, and the first plate 12 is connected to the first plate 11 and can seal the openings of the plurality of grooves to form a first flow channel 13. The first flow channel 13 is connected to a joint 7, and the first flow channel 13 can be connected to an external pipe body through the joint 7 and can form a loop with the external pipe body, so that a heat exchange medium can be transported to the first flow channel 13.

[0061] In this example, the material of the first plate 11 may be an aluminum alloy material or other metal materials, etc. For example, it may be 4343 aluminum alloy, 4045 aluminum alloy, 3003 aluminum alloy or 3003mod aluminum plate, or 3003 composite 6 series aluminum alloy or composite 4 series aluminum alloy, etc., or other composite materials of various types, or may also be a steel-aluminum composite material, etc. The material of the second plate 12 may be the same as that of the first plate 11.

[0062] In this example, the first plate 11 and the second plate 12 can be integrally formed, that is, the first flow channel 13 is formed in the plate body, thereby forming the heat exchange body 1.

[0063] In an example, Figure 4 and Figure 5 As shown, a second flow channel 4 is formed between the reinforcing plate 2 and the second plate 12. The second flow channel 4 is used to fill a heat exchange medium to improve the heat exchange efficiency of the heat exchange body 1.

[0064] like Figure 4 and Figure 5 As shown, in this example, the reinforcing plate 2 is connected to the side of the second plate 12 away from the first plate 11, and a second flow channel 4 is formed between the reinforcing plate 2 and the second plate 12. Heat exchange medium can also flow in the second flow channel 4, thereby improving the heat exchange efficiency of the heat exchange body 1.

[0065] For example, the second plate 12 is provided with a plurality of grooves toward the reinforcing plate 2, and the reinforcing plate 2 is connected to the second plate 12 and can seal the openings of the plurality of grooves to form the second flow channel 4. The second flow channel 4 is also connected to the joint 7, and the second flow channel 4 can be connected to the external pipe body through the joint 7 and can form a loop with the external pipe body, so that the heat exchange medium can be transported to the second flow channel 4.

[0066] In an example, Figure 4 and Figure 5 As shown, the second plate 12 is a corrugated plate, and the first plate 11 and the reinforcing plate 2 are respectively connected to the two sides of the second plate 12 along the thickness direction, so that the first flow channel 13 is formed between the second plate 12 and the first plate 11, and the second flow channel 4 is formed between the second plate 12 and the reinforcing plate 2.

[0067] like Figure 4 and Figure 5 As shown, in this example, the second plate 12 can be a corrugated plate. That is, grooves can be formed on both sides of the second plate 12 in the thickness direction. The first plate 11 and the reinforcing plate 2 are respectively connected to the two sides of the second plate 12 in the thickness direction, so that a first flow channel 13 can be formed between the first plate 11 and the second plate 12, and a second flow channel 4 can be formed between the reinforcing plate 2 and the second plate 12. The process of processing the second plate 12 into a corrugated plate is simple. For example, it can be formed into a corrugated plate by continuous bending. Alternatively, it is also possible to form a corrugated plate by processing groove structures on both sides of the thickness direction of the second plate 12.

[0068] In this example, the cross section of the groove of the second plate 12 may be semicircular, trapezoidal, rectangular, or other irregular shapes, which may be determined by those skilled in the art according to actual conditions and are not specifically limited here.

[0069] In an example, Figure 3 and Figure 4 As shown, the second plate 12 has a flow channel area and a border area 121 , and the reinforcing plate 2 arranged on both sides includes a first part and a second part, the first part and the flow channel area form the second flow channel 4 , and the second part is connected to the border area 121 .

[0070] like Figure 4 As shown, the second plate 12 has a flow channel area and a frame area 121 located outside the flow channel area. That is, the frame area 121 is located at the edge of the second plate 12. The first part of the reinforcing plate 2 arranged on both sides of the second plate 12 is connected to the flow channel area, and the second part of the reinforcing plate 2 is connected to the frame area 121. The first part of the reinforcing plate 2 and the flow channel area form a second flow channel 4. The second part of the reinforcing plate 2 is connected to the frame area 121, so that the strength of the frame area 121 can be improved to improve the force strength of the frame area 121.

[0071] In an example, Figure 4 As shown, the thickness of the second portion is greater than the thickness of the first portion.

[0072] like Figure 4 As shown, in this example, the thickness of the second portion of the reinforcing plate 2 is greater than the thickness of the first portion of the reinforcing plate 2 , and the border area 121 of the second plate 12 serves as a stress point, which can further improve the strength of the second plate 12 .

[0073] In this example, the flow channel area of ​​the second plate 12 is a corrugated plate, and the frame area 121 of the second plate 12 is a flat plate. The first portion is connected to the flow channel area, and the second portion of the reinforcing plate 2 is connected to the frame area 121. The thickness of the second portion is greater than the thickness of the first portion, so that the side of the reinforcing plate 2 away from the second plate 12 can remain flat.

[0074] In an example, Figures 1 to 5 As shown, the heat exchange assembly further includes a heat insulation layer 5, which is disposed on the heat exchange body 1, and a plurality of reinforcing plates 2 are located between the heat insulation layer 5 and the heat exchange body 1. The heat insulation layer 5 can insulate the heat exchange body 1 to improve the heat exchange efficiency of the heat exchange body 1 to the heat exchange equipment.

[0075] like Figure 1 , Figure 4 and Figure 5As shown, in this example, the heat-insulating layer 5 is arranged on the heat-insulating layer 5 to have a heat-insulating effect on the heat-exchanging body 1, and the reinforcing plate 2 is located between the heat-insulating layer 5 and the heat-exchanging body 1, which can reduce the space occupied by the reinforcing plate 2. That is, the heat-insulating layer 5 is provided with an avoidance groove toward the heat-exchanging body 1, and the reinforcing plate 2 is embedded in the avoidance groove, thereby reducing the additional space occupied by the reinforcing plate 2, so that the structure of the heat-exchanging assembly is more compact.

[0076] In this example, the thermal insulation layer 5 can be made of polyurethane foam, silicon foam, aerogel, foam rubber, foam polyethylene, foam polypropylene, foam polystyrene, foam ethylene-vinyl acetate copolymer, vacuum board, foam EPDM, etc., or can be made of honeycomb composite materials, etc. Of course, the specific material of the thermal insulation layer 5 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0077] In this example, the thickness of the thermal insulation layer 5 is 0.5 mm to 10 mm, so as to ensure that the thermal insulation layer 5 can have good thermal insulation materials and reduce the overall thickness of the heat exchange component. For example, the thickness of the thermal insulation layer 5 at the position corresponding to the reinforcing plate 2 is smaller, and the thickness at other positions is larger. Among them, the thickness of the thermal insulation layer 5 can be 0.5 mm, 1 mm, 3 mm, 7 mm or 10 mm, etc., which can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0078] like Figure 4 and Figure 5 As shown, in this example, a glue layer 6 is provided between the thermal insulation layer 5 and the heat exchange body 1. The thermal insulation layer 5 can be connected to the heat exchange body 1 by adhesive bonding, which can effectively block water vapor and achieve heat preservation. Among them, the adhesive material of the glue layer 6 can be a polyurethane system, an epoxy system, an organosilicon / modified silane system, an acrylic system, etc. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0079] like Figure 4 and Figure 5 As shown, in this example, the second plate 12 is a corrugated plate, and the adhesive layer 6 can be disposed in a groove of the second plate 12 .

[0080] In this example, the process for setting the glue layer 6 may be potting or glueing by glue-spraying equipment to form the glue layer 6. The curing time of the glue layer 6 needs to be greater than or equal to 30 minutes to make the glue layer 6 better cured and achieve the effect of the glue layer 6.

[0081] According to another embodiment of the present invention, a battery pack is provided. Figure 6As shown, the battery pack also includes the heat exchange assembly of the above embodiment. The heat exchange body 1 is provided with a plurality of reinforcing plates 2 along the length direction, and the plurality of reinforcing plates 2 are respectively provided at both ends and the middle of the heat exchange body 1, so that the strength of the heat exchange body 1 can be improved, and compared with increasing the thickness of the heat exchange body 1 as a whole, by providing a plurality of reinforcing plates 2 at intervals on the heat exchange body 1, the strength of the heat exchange body 1 can be improved, and the weight of the heat exchange body 1 can be reduced.

[0082] In an example, Figure 6 As shown, the battery pack further includes a tray 8 , which is suitable for carrying a battery module 10 , and the tray 8 is connected to a side of the heat exchange body 1 away from the reinforcing plate 2 .

[0083] like Figure 6 As shown, the heat exchange body 1 and the tray 8 are integrated, and the tray 8 is suitable for carrying the battery module 10. The heat exchange body 1 can complete heat exchange with the battery module 10 through the tray 8. That is, the battery module 10 can be heated or cooled.

[0084] In one example, the battery pack further includes a sealing cover 9 , which is suitable for sealing the battery module 10 , and the sealing cover 9 is connected to a side of the heat exchange body 1 facing away from the reinforcing plate 2 .

[0085] In this example, the heat exchange body 1 can also be integrated with the sealing cover 9, and the sealing cover 9 is suitable for sealing the battery module 10. The heat exchange body 1 can perform heat exchange with the battery module 10 through the sealing cover 9. That is, the battery module 10 can be heated or cooled.

[0086] In one example, the heat exchange body 1 may also be a side beam structure of a battery pack, etc. Regarding the specific configuration of the heat exchange body 1, those skilled in the art may determine it according to actual conditions, and no specific limitation is made here.

[0087] According to another aspect of the present invention, an electric device is provided, which includes the battery pack of the above embodiment.

[0088] In this example, the heat exchange body 1 in the battery pack is provided with a plurality of reinforcing plates 2 along the length direction, and the plurality of reinforcing plates 2 are respectively provided at both ends and the middle portion of the heat exchange body 1, thereby improving the strength of the heat exchange body 1. In addition, compared with increasing the overall thickness of the heat exchange body 1, by arranging a plurality of reinforcing plates 2 at intervals on the heat exchange body 1, the strength of the heat exchange body 1 can be improved and the weight of the heat exchange body 1 can be reduced.

[0089] The electrical equipment may be an electric car, an electric motorcycle or a battery energy storage device, etc. Those skilled in the art may determine the specific situation based on the actual situation, and no specific limitation is made here.
