Description

[Technical field]

[0001] TECHNICAL FIELD This application relates to the field of battery technology, and in particular to thermal management components, batteries and power consuming devices.

[0002] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese patent application CN202221040676.X, entitled "Thermal Management Member, Battery and Power Consumption Device," filed on April 29, 2022, the entire contents of which are incorporated herein by reference. [Background technology]

[0003] At present, with the rapid development of new energy vehicles, power batteries have been increasingly noticed and recognized. In order to ensure the safe and stable operation of new energy vehicles, it is necessary to implement effective thermal management for the battery module.

[0004] The battery cells inside a battery are prone to external expansion as the battery is used for an extended period of time, which tends to reduce the contact area between the battery cells and the thermal management components inside the battery, affecting the thermal conduction efficiency of the thermal management components and the battery cells. Summary of the Invention [Problem to be solved by the invention]

[0005] The present application provides a thermal management member, a battery, and a power consumption device, which realizes that the thermal management member can be compressed and slightly deformed, thereby reducing the thermal conduction effect between the battery cell and the thermal management member due to the expansion of the battery cell. [Means for solving the problem]

[0006] According to a first aspect, an embodiment of the present application provides a thermal management member, the thermal management member including a first wall, a second wall spaced apart from the first wall and having an accommodation space between the first wall and the second wall, and a support member disposed within the accommodation space along an extension direction inclined to the first wall or the second wall.

[0007] In the above embodiment, the thermal management member includes a first wall and a second wall spaced apart from the first wall, and has a storage space between the first wall and the second wall. The thermal management member may be used to store a heat exchange medium in the storage space, for example, a medium for performing heat exchange after cooling or a medium for performing heat exchange after heating, specifically, for example, water, a coolant, etc. Thus, when at least one of the first wall and the second wall contacts a target member such as a battery cell or a battery module, the temperature of the target member is adjusted by a heat transfer method. Here, a support member is provided in the storage space, and the support member is installed along an extension direction that is inclined to the first wall or the second wall. Therefore, compared with a method in which the support member is installed along an extension direction that is perpendicular to the first wall or the second wall, the support force of the support member of the present application against the first wall and the second wall is relatively small. Thus, when the thermal management member is subjected to a pressing force along the stacking direction of the first wall and the second wall, the thermal management member is easily slightly deformed. As a result, the risk of compressive deformation being required when assembling the battery pack, for example by sealing it in a box, can be met, while at the same time reducing the risk of the thermal management member breaking when subjected to relatively large concentrated stresses.

[0008] In some embodiments, the number of support members is multiple, and the multiple support members are spaced apart between the first wall and the second wall.

[0009] In the above embodiment, the support members are disposed at intervals between the first wall and the second wall, so that the storage space can be divided into a plurality of flow paths. Therefore, when the heat exchange medium enters the storage space, it can be diverted into a plurality of flow paths. As a result, when the heat management member contacts the target member, the temperature of each part of the target member can be adjusted relatively uniformly. At the same time, the support members are disposed at intervals, so that the heat management member can be prevented from having a relatively high local strength and being difficult to compress, and the reliability of the overall heat exchange function can be improved.

[0010] In some embodiments, the first wall is adapted to contact and thermally conduct the target member, and the angle between the support member and a plane in which the first wall resides is in the range of 35° to 55°.

[0011] In the above embodiment, when the angle between the support member and the plane on which the first wall is located is smaller than 35°, the support force of the support member against the first wall and the second wall is relatively large, and the heat management member is not easily compressed. When the angle between the support member and the plane on which the first wall is located is larger than 55°, the support force of the support member against the first wall and the second wall is relatively small, and the heat management member is damaged when subjected to a relatively large concentrated stress. Or, the amount of compressive deformation is relatively large, and the first wall contacts the second wall and blocks the storage space. Therefore, by setting the angle between the support member and the plane on which the first wall is located within the range of 35° to 55°, not only is the heat management member easily compressed and slightly deformed, but the risk of damage to the heat management member when subjected to a relatively large concentrated stress can be reduced. Or, the amount of compressive deformation is relatively large, and the occurrence of a situation in which the first wall contacts the second wall and blocks the storage space can be avoided.

[0012] In some embodiments, the support members are arranged in parallel.

[0013] In the above embodiment, the angles between the support members and the plane on which the first wall is located are all the same, and the support forces of the support members on the first wall and the second wall are all the same, which reduces the risk of deformation due to a relatively large local load on the thermal management member, and at the same time contributes to improving the aesthetics of the product.

[0014] In some embodiments, at least two of the support members form different angles with the first wall.

[0015] In the above embodiment, unlike the method of installing multiple support members in parallel, at least two support members may be set to different angles between the plane on which the first wall is located. For example, the angle between one support member and the plane on which the first wall is located may be 35°, and the angle between another adjacent support member and the plane on which the first wall is located may be 45°. In this case, the same function of supporting the first wall and the second wall can be achieved, and the thermal management member can be slightly deformed, and the structure and principle are both simple and easy to implement.

[0016] In some embodiments, the thermal management member includes a connecting end, the connecting end being located between and connecting the first wall and the second wall, and the thermal management member further includes at least one end stiffener disposed between the first wall and the second wall and proximate the connecting end.

[0017] In the above embodiment, at least one end reinforcement member is provided between the first wall and the second wall and adjacent to the connecting end connecting the first wall and the second wall, so that the end reinforcement member serves to support the connecting end between the first wall and the second arm, improves the local strength of the connecting end, and prevents the connecting end from breaking when it is subjected to a relatively large stress.

[0018] Specifically, the number of end reinforcing members is two, and the two end reinforcing members are used to support two connecting ends of the first wall and the second wall, respectively.

[0019] In some embodiments, a gap is provided between the end stiffening member and the connecting end.

[0020] In the above embodiment, the end reinforcing member and the connecting end are spaced apart from each other, so that the heat exchange medium can flow through the gap between the end reinforcing member and the connecting end, and the connecting end can also conduct heat, thereby further improving the uniformity of the heat conduction of the thermal management member.

[0021] In some embodiments, the thermal management member further includes a first reinforcing member disposed on a surface of the first wall facing the second wall and spaced apart from the second wall.

[0022] In the above embodiment, the first reinforcing member is installed on the surface of the first wall facing the second wall, and the first reinforcing member and the second wall are installed at a distance from each other. This not only improves the rigidity of the first wall, but also prevents the first wall from directly contacting the second wall when the thermal management member is pressed and deformed. Furthermore, it prevents the storage space from being blocked, preventing the heat exchange medium from flowing.

[0023] In some embodiments, the device further includes a second reinforcing member disposed on a surface of the second wall facing the first wall and spaced apart from the first wall.

[0024] In the above embodiment, the second reinforcing member is installed on the surface of the second wall facing the first wall, and the second reinforcing member and the first wall are installed at a distance from each other. This not only improves the rigidity of the second wall, but also prevents the second wall from directly contacting the first wall when the thermal management member is pressed and deformed. Furthermore, it prevents the storage space from being blocked, preventing the heat exchange medium from flowing.

[0025] In some embodiments, the second reinforcing member and the first reinforcing member are offset from each other when projected along a stacking direction of the first wall and the second wall.

[0026] In the above embodiment, the first reinforcing member and the second reinforcing member are disposed at different positions along the stacking direction of the first wall and the second wall. Therefore, when the first wall and the second wall are pressed and brought close to each other, the first reinforcing member and the second reinforcing member can be prevented from contacting each other. This makes it possible to prevent the first reinforcing member and the second reinforcing member from contacting each other, which would prevent the thermal management member from being deformed by pressure.

[0027] In some embodiments, along a stacking direction of the first wall and the second wall, the size of the first reinforcing member and / or the second reinforcing member is smaller than the size of the end reinforcing member.

[0028] In the above embodiment, the size of the first reinforcing member along the stacking direction of the first wall and the second wall is smaller than that of the end reinforcing member. Or, the size of the second reinforcing member along the stacking direction of the first wall and the second wall is smaller than that of the end reinforcing member. Or, the size of the first reinforcing member and the second reinforcing member along the stacking direction of the first wall and the second wall is both smaller than that of the end reinforcing member. Since the end reinforcing member plays a role of supporting the first wall and the second wall, the first reinforcing member and the second reinforcing member prevent the occurrence of notches due to the first wall and the second wall coming into direct contact due to deformation by pressing. By making the size of the first reinforcing member and the second reinforcing member along the stacking direction of the first wall and the second wall smaller than that of the end reinforcing member, it is possible to prevent the connection end of the first wall and the second wall from being damaged by a relatively large stress. At the same time, the first wall and the second wall do not come into direct contact when the thermal management member is pressed, and the occurrence of a situation in which the accommodation space is blocked is avoided.

[0029] According to a second aspect, an embodiment of the present application provides a battery, the battery comprising a target member and a thermal management member according to any one of the embodiments of the first aspect in thermal conductive contact with the target member through the first wall.

[0030] In the above embodiments, the target member may be a member such as a battery cell group. A battery according to the embodiment of the second aspect includes the thermal management member according to any one of the embodiments of the first aspect, and thus has the technical effect of any one of the above embodiments. No further description is provided here.

[0031] In some embodiments, the battery further includes a current collecting member connected to the thermal management member, the current collecting member including a current collecting path, the current collecting path communicating with the receiving space of the thermal management member.

[0032] In the above embodiment, the current collecting path of the current collecting member is connected to the accommodation space of the thermal management member, so that the heat exchange medium enters the accommodation space through the current collecting member, thereby realizing the temperature adjustment of the target member, and the heat exchange medium in the accommodation space can be returned to the current collecting member after heat exchange, thereby realizing circulating heat conduction.

[0033] According to a third aspect, an embodiment of the present application provides a power consuming device, comprising a battery according to the embodiment of the second aspect, said battery being adapted to power said power consuming device.

[0044] At present, in view of the development of the market situation, the application of power batteries is becoming more and more widespread. Power batteries are not only used in energy storage power systems such as hydroelectric, thermal, wind and solar power stations, but also widely used in electric transportation tools such as electric bicycles, electric motorcycles, electric cars, and military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand for them is also continuously increasing.

[0045] Power batteries have different electrical cycle performances at different environmental temperatures. If the environmental temperature is too high or too low, it will cause the cycle performance of the power battery to decrease, and thus shorten its service life. In order to ensure the safety, stable performance and good operation of new energy vehicles, it is necessary to carry out effective thermal management of the battery module, and control the battery module to always operate within a suitable temperature range.

[0046] The inventors discovered that as the battery usage time increases, the battery cells inside the battery are prone to expanding in shape due to internal gas generation, which reduces the thermal conduction area between the battery cell or a module formed by combining multiple battery cells and the thermal management component, lowers the heat exchange efficiency, and makes the battery less effective.

[0047] Based on the above idea, the inventors have conducted extensive research and have designed the following thermal management member: a support member is provided between a first wall and a second wall of the thermal management member, and the support member is provided in the accommodation space along an extending direction that is inclined toward the first wall and the second wall. This can appropriately weaken the supporting force of the support member against the first wall and the second wall. As a result, the thermal management member can be compressed and slightly deformed in response to the expansion of the external shape of the battery cell or battery module, thereby reducing the reduction in the heat exchange area between the two.

[0048] The thermal management components and batteries according to the embodiments of the present application can be used in various different power consuming devices to solve the above problems. Such power consuming devices may be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, battery cars, electric cars, steamships, spacecraft, etc. Here, the electric toys may include stationary or mobile electric toys, such as game consoles, electric car toys, electric steamship toys, and electric plane toys, and the spacecraft may include airplanes, rockets, space shuttles, and spaceships, etc.

[0049] For convenience of explanation, the following embodiment will be described by taking as an example that the power consuming device in one embodiment of the present application is a vehicle 1000.

[0050] Referring to FIG. 1, FIG. 1 is a structural schematic diagram of a vehicle 1000 according to some embodiments of the present application. The vehicle 1000 may be a gasoline vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or a range extender vehicle, etc. A battery 100 is installed inside the vehicle 1000, and the battery 100 may be installed at the bottom, front, or rear of the vehicle 1000. The battery 100 may be used to supply power to the vehicle 1000, for example, the battery 100 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may further include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to supply power to the motor 300, for example, for use in starting the vehicle 1000, navigation, and operating power consumption needs during driving.

[0051] In some embodiments of the present application, the battery 100 can not only serve as the operating power source for the vehicle 1000, but can also serve as the propulsion power source for the vehicle 1000, providing propulsion power to the vehicle 1000 in place of, or in place of, fuel oil or natural gas.

[0052] Referring to FIG. 2, FIG. 2 is a schematic exploded view of a battery 100 according to some embodiments of the present application. The battery 100 includes a housing 10 and a battery cell 20 housed in the housing 10. Here, the housing 10 is used to provide a housing space for the battery cell 20, and the housing 10 may adopt various structures. In some embodiments, the housing 10 may include a first part 11 and a second part 12. The first part 11 and the second part 12 are placed over each other to jointly define a housing space for housing the battery cell 20. The second part 12 is a hollow structure with an opening at one end, and the first part 11 may be a plate-like structure, and the first part 11 is placed over the opening side of the second part 12, so that the first part 11 and the second part 12 define the housing space. The first part 11 and the second part 12 may both be hollow structures with an opening at one end, and the opening side of the first part 11 is placed over the opening side of the second part 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 may have various shapes, for example, a cylindrical body, a rectangular parallelepiped, etc.

[0053] In the battery 100, the battery cell 20 may be a plurality of cells. The plurality of cells 20 may be connected in series, in parallel, or in series-parallel. The series-parallel connection means that the plurality of cells 20 may be connected in series or in parallel. The plurality of cells 20 may be directly connected in series, in parallel, or in series-parallel, and the entirety of the plurality of cells 20 may be housed in the housing 10. Of course, the battery 100 may be a battery module formed by first connecting the plurality of cells 20 in series, in parallel, or in series-parallel, and then the plurality of cells 20 may be connected in series, in parallel, or in series-parallel to form a battery module, and then the battery modules may be connected in series, in parallel, or in series-parallel to form an integrated battery module, and then housed in the housing 10. The battery 100 may further include an electrical connection member for realizing an electrical connection between the plurality of cells 20. The battery cell 20 is the minimum unit that constitutes the battery 100. As shown in FIG. 3, the battery cell 20 includes an electrical connection member, and the electrical connection member is used to electrically connect two adjacent cells 20.

[0054] Here, each battery cell 20 may be a secondary battery cell or a primary battery cell, and may be, but is not limited to, a lithium-sulfur battery cell, a sodium-ion battery cell, or a magnesium-ion battery cell. The battery cell 20 may have a cylindrical shape, a flat shape, a rectangular shape, or other shapes.

[0055] Referring to Fig. 3, Fig. 3 is a schematic diagram of a local structure of a battery according to some embodiments of the present application. According to some embodiments of the present application, a battery 100 according to the embodiments of the present application includes a target member and a thermal management member 30, and a first wall of the thermal management member 30 is in contact with the target member and is used for heat exchange with the target member. Here, the target member may be a member such as a battery cell or a battery module.

[0056] 3, according to some embodiments of the present application, the battery 100 further includes a current collecting member. The current collecting member is connected to the thermal management member 30 and includes a current collecting path. The current collecting path communicates with the accommodation space 303 of the thermal management member 30. By communicating the current collecting path of the current collecting member with the accommodation space 303 of the thermal management member 30, the heat exchange medium can enter the accommodation space 303 through the current collecting member, thereby realizing the temperature adjustment for the target member, and the heat exchange medium in the accommodation space 303 can be returned to the current collecting member after heat exchange, realizing circulating heat exchange.

[0057] 3 and 4, Fig. 4 is a cross-sectional structural schematic diagram of a thermal management member 30 according to some embodiments of the present application. As shown in Fig. 4, the thermal management member 30 according to some embodiments of the present application includes a first wall, a second wall spaced apart from the first wall and having an accommodation space 303 between the first wall and the second wall, and a support member 304 installed in the accommodation space 303 along an extending direction inclined to the first wall or the second wall.

[0058] The first wall and the second wall are heat conductive members and are used for heat exchange with the target member.

[0059] The receiving space 303 communicates across both ends of the thermal management member 30 and is used for passing a heat exchange medium, such as water, through the receiving space 303. When at least one of the first wall and the second wall contacts a target member, such as a battery cell, a battery module, etc., the temperature of the target member is adjusted by heat transfer.

[0060] Exemplarily, the support member 304 may be a support plate or a support rib, etc. The specific shape of the support member 304 is not particularly limited, and may be, for example, a straight shape or a bent shape.

[0061] At least one support member 304 is provided in the receiving space 303, and the at least one support member 304 is installed along an inclined extension direction to the first wall or the second wall, so that the support force of the support member 304 of the present application to the first wall and the second wall is relatively small compared to the mode in which the support member 304 is installed along an extension direction perpendicular to the first wall or the second wall. Therefore, when the thermal management member 30 is subjected to a pressing force along the stacking direction of the first wall and the second wall, the thermal management member 30 is easily deformed slightly. As a result, the risk of compressive deformation required when the battery cell 20 is sealed in a box and assembled can be satisfied, and at the same time, the risk of damage to the thermal management member 30 when it is subjected to a relatively large concentrated stress can be reduced.

[0062] According to some embodiments of the present application, the number of the support members 304 is plural. The support members 304 are spaced apart between the first wall and the second wall.

[0063] By providing a plurality of support members 304 at intervals between the first wall and the second wall, the support strength of the heat management member 30 can be improved and the accommodation space 303 can be divided into a plurality of flow paths. Therefore, when the heat exchange medium enters the accommodation space 303, the heat exchange medium can be divided into a plurality of flow paths. As a result, when the heat management member 30 contacts the target member, the temperature of each portion of the target member can be adjusted relatively uniformly.

[0064] According to some embodiments of the present application, the first wall is used to contact and conduct heat with the target member, and the angle between the support member 304 and the direction perpendicular to the plane in which the first wall is located is in the range of 35° to 55°.

[0065] When the angle between the support member 304 and the direction perpendicular to the plane on which the first wall is located is smaller than 35°, the support force of the support member 304 against the first wall and the second wall is relatively large, and the heat management member 30 is not easily compressed. When the angle between the support member 304 and the direction perpendicular to the plane on which the first wall is located is larger than 55°, the support force of the support member 304 against the first wall and the second wall is relatively small, and the heat management member 30 is damaged when subjected to a relatively large concentrated stress, or the amount of compressive deformation is relatively large, so that the heat management member 30 contacts the second wall and blocks the accommodation space 303. Therefore, by setting the angle between the support member 304 and the direction perpendicular to the plane on which the first wall is located within the range of 35° to 55°, not only is the heat management member 30 easily compressed and slightly deformed, but also the risk of damage when the heat management member 30 is subjected to a relatively large concentrated stress can be reduced, or the occurrence of a situation in which the heat management member 30 contacts the second wall and blocks the accommodation space 303 due to the relatively large amount of compressive deformation can be avoided.

[0066] Referring to FIG. 4, according to some embodiments of the present application, multiple support members 304 are positioned in parallel.

[0067] That is, the angles between the multiple support members 304 and the plane on which the first wall is located are all the same, and the support forces of the support members 304 on the first wall and the second wall are all the same. This reduces the risk of deformation due to a relatively large localized force being received by the thermal management member 30, and at the same time contributes to improving the aesthetics of the product.

[0068] 5, which is a schematic cross-sectional view of another thermal management member 30 according to some embodiments of the present application. According to some embodiments of the present application, at least two support members 304 each have a different angle with the first wall.

[0069] Unlike the method of installing multiple support members 304 in parallel, at least two of the support members 304 may have different angles between them and the plane on which the first wall is located. For example, the angle between one support member 304 and the plane on which the first wall is located may be 35°, and the angle between another adjacent support member 304 and the plane on which the first wall is located may be 45°. In this case, the same function of supporting the first and second walls can be achieved, and the thermal management member 30 can be slightly deformed. The structure and principle are both simple and easy to implement.

[0070] 4 and 5, according to some embodiments of the present application, the thermal management member 30 includes a connecting end 306. The connecting end 306 is located between the first wall and the second wall and connects the first wall and the second wall. The thermal management member 30 further includes at least one end stiffener 305 disposed between the first wall and the second wall and proximate to the connecting end 306.

[0071] Illustratively, the connecting end 306 is an arc surface structure, but may also be a straight edge for connecting the first wall and the second wall.

[0072] Illustratively, the end reinforcement members 305 may be reinforcement plates or reinforcement ribs or the like.

[0073] Illustratively, the number of the end reinforcement members 305 is two, and the two end reinforcement members 305 are used to support the two connecting ends 306 of the first wall and the second wall, respectively.

[0074] By disposing at least one end stiffener 305 between the first wall and the second wall and adjacent to the connecting end 306 connecting the first wall and the second wall, the end stiffener 305 serves to support the connecting end 306 between the first wall and the second arm, thereby improving the local strength of the connecting end 306 and preventing the connecting end 306 from breaking when subjected to a relatively large stress.

[0075] 4 and 5, according to some embodiments of the present application, a gap is provided between the end stiffening member 305 and the connecting end 306.

[0076] That is, the end reinforcing member 305 and the connecting end 306 are disposed with a gap therebetween. Therefore, the heat exchange medium can flow through the gap between the end reinforcing member 305 and the connecting end 306, and the connecting end 306 can also conduct heat. This can further improve the uniformity of the heat conduction of the thermal management member 30.

[0077] Referring to Figures 4 and 5, according to some embodiments of the present application, the thermal management member 30 further includes a first reinforcing member 307 provided on a surface of the first wall facing the second wall and spaced apart from the second wall.

[0078] Exemplarily, the first reinforcing member 307 may be a reinforcing plate or a reinforcing rib, or the like.

[0079] By providing the first reinforcing member 307 on the surface of the first wall facing the second wall and providing a gap between the first reinforcing member 307 and the second wall, the first reinforcing member 307 not only improves the rigidity of the first wall, but also prevents the first wall from coming into direct contact with the second wall when the thermal management member 30 is pressed and deformed, and also prevents the storage space 303 from being blocked, preventing the heat exchange medium from flowing.

[0080] 4 and 5, according to some embodiments of the present application, the thermal management member 30 further includes a second reinforcing member 308 provided on a surface of the second wall facing the first wall and spaced apart from the first wall.

[0081] Exemplarily, the second reinforcing member 308 may be a reinforcing plate or a reinforcing rib, etc. The size of the second reinforcing member 308 may be the same as or different from the size of the first reinforcing member 307.

[0082] By providing the second reinforcing member 308 on the surface of the second wall facing the first wall and providing a gap between the second reinforcing member 308 and the first wall, the second reinforcing member 308 not only improves the rigidity of the second wall, but also prevents the second wall from coming into direct contact with the first wall when the thermal management member 30 is pressed and deformed, and also prevents the storage space 303 from being blocked, preventing the flow of the heat exchange medium.

[0083] Referring to Figures 4 and 5, according to some embodiments of the present application, when projected along the stacking direction of the first wall and the second wall, the second reinforcing member 308 and the first reinforcing member 307 are installed with a staggered position.

[0084] By displacing the first reinforcing member 307 and the second reinforcing member 308 in the stacking direction of the first wall and the second wall, it is possible to prevent the first reinforcing member 307 and the second reinforcing member 308 from contacting each other when the first wall and the second wall are pressed close to each other. This makes it possible to prevent the first reinforcing member 307 and the second reinforcing member 308 from contacting each other, which would prevent the thermal management member 30 from being deformed by pressure.

[0085] 4 and 5, according to some embodiments of the present application, along the stacking direction of the first wall and the second wall, the size of the first reinforcing member 307 and / or the second reinforcing member 308 is smaller than the end reinforcing member 305.

[0086] That is, the size of the first reinforcing member 307 along the stacking direction of the first wall and the second wall is smaller than that of the end reinforcing member 305. Or, the size of the second reinforcing member 308 along the stacking direction of the first wall and the second wall is smaller than that of the end reinforcing member 305. Or, the sizes of the first reinforcing member 307 and the second reinforcing member 308 along the stacking direction of the first wall and the second wall are both smaller than that of the end reinforcing member 305. Since the end reinforcing member 305 plays a role in supporting the first wall and the second wall, the first reinforcing member 307 and the second reinforcing member 308 prevent the occurrence of notches caused by direct contact between the first wall and the second wall due to pressure deformation. By making the size of the first reinforcing member 307 and the second reinforcing member along the stacking direction of the first wall and the second wall smaller than that of the end reinforcing member 305, it is possible to prevent the connection end 306 of the first wall and the second wall from being damaged by relatively large stress, while at the same time preventing the first wall and the second wall from coming into direct contact when the thermal management member 30 is pressed, and further avoiding the occurrence of a situation in which the accommodating space 303 is blocked.

[0087] 3 to 5, according to some embodiments of the present application, the embodiments of the present application provide a thermal management member 30. The thermal management member 30 includes a first wall and a second wall connected to the first wall. An accommodation space 303 is defined between the first wall and the second wall, and at least one support member 304 is provided between the first wall and the second wall. The at least one support member 304 is provided in the accommodation space 303 along an extending direction inclined to the first wall and the second wall. At the same time, an end reinforcing member 305 is provided at a connecting end 306 adjacent to the first wall and the second wall, the end reinforcing member 305 being provided at a distance from the connecting end 306. At least one first reinforcing member 307 is provided on a surface of the first wall facing the second wall. The first reinforcing member 307 is provided at a distance from the second wall, and a second reinforcing member 308 is provided on a surface of the second wall facing the first wall. The second reinforcing member 308 is provided at a distance from the first wall. Here, at least one support member 304 is installed at an incline along the extension direction of the first wall and the second wall, so as to appropriately weaken the support force against the first wall and the second wall, so that the thermal management member 30 can be compressed and slightly deformed, thereby satisfying the usage scenarios that require the thermal management member 30 to be compressible.

Although the present application has been described in detail with reference to the embodiments, it should be understood that those skilled in the art can make modifications to the technical solutions described in the embodiments, or make equivalent substitutions for some or all of the technical features thereof.
