[0079] At present, from the development of market situation, the application of power battery is more and more widely. Power battery is not only applied to energy storage power supply system of water power, thermal power, wind power and solar power station, but also widely applied to electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment, aerospace and other fields. With the continuous expansion of the application field of power battery, the demand of its market is also increasing.

[0080] The battery cells in the battery need to be in a certain temperature range when operating. When the temperature in the battery is higher or lower than this range, the stability and performance of the battery will be greatly affected. For example, in hot weather, the battery cells need to be cooled to keep the temperature in the battery within the required temperature range. In cold weather, the battery cells need to be heated to keep the temperature in the battery within the required temperature range.

[0081] In some related technologies, a thermal management component is provided in the battery, which includes a plurality of heat exchange components in communication with each other, and the battery cells are located between two adjacent heat exchange components. The heat exchange component is provided with a heat exchange channel, and the heat exchange medium flows in the heat exchange channel and exchanges heat with the battery cells, so that the heat or cold of the heat exchange medium is transferred to the battery cells, realizing heat exchange with the battery cells, heating or cooling the battery cells, realizing temperature regulation, and making the battery cells can be in a more suitable temperature range.

[0082] However, the heat exchange element is provided with a connecting portion, when two adjacent heat exchange elements are assembled, one end of a connecting pipe is sealingly connected with the connecting portion of one of the heat exchange elements, and the other end of the connecting pipe is sealingly connected with the connecting portion of the other heat exchange element, so as to connect the heat exchange channels of the two adjacent heat exchange elements. In this way, the heat exchange medium can flow through the heat exchange channels of the two adjacent heat exchange elements, so as to increase the heat exchange surface of the battery monomer, and the battery monomer has good heat exchange effect. However, the connecting pipe needs to be connected with the connecting portions of the two adjacent heat exchange elements respectively, and the connection operation is complicated, and the assembly efficiency of the thermal management component is low. In addition, the two ends of the connecting pipe need to be sealed with the two adjacent heat exchange elements, and the sealing positions are more, which is not conducive to reducing the risk of leakage between the two adjacent heat exchange elements.

[0083] Therefore, the battery provided in the embodiments of the present application includes a thermal management component and at least one battery monomer, the thermal management component includes at least two heat exchange elements, at least one battery monomer is arranged between two adjacent heat exchange elements, and the heat exchange element has a heat exchange channel for heat exchange with the battery monomer. The first connecting portion and the second connecting portion are sealingly inserted to connect the heat exchange channels of the two adjacent heat exchange elements.

[0084] The thermal management component with the above structure exchanges heat with the battery monomer through the heat exchange channel of the heat exchange element, so as to realize temperature control of the battery monomer. When the thermal management component is assembled, the first connecting portion of one heat exchange element is inserted with the second connecting portion of the other heat exchange element, so as to realize the connection of the two adjacent heat exchange elements in the thermal management component. The connection operation is simple, which is conducive to improving the assembly efficiency of the thermal management component and reducing the manufacturing cost of the battery. In addition, after the first connecting portion and the second connecting portion of the two adjacent heat exchange elements are sealingly inserted, the sealing connection positions between the two adjacent heat exchange elements are less, which is conducive to reducing the risk of leakage of the thermal management component, improving the sealing effect of the thermal management component, and improving the use reliability of the battery.

[0085] The thermal management component disclosed in the embodiments of the present application can be applied to a battery, and the battery can be used as a power supply for a power consumption device. The power consumption device can be, but is not limited to, a mobile phone, a tablet computer, a notebook computer, an electric toy, an electric tool, an electric vehicle, an electric automobile, a ship, a spacecraft, etc. The electric toy can include a fixed or mobile electric toy, such as a game console, an electric automobile toy, an electric ship toy, an electric aircraft toy, etc. The spacecraft can include an airplane, a rocket, a space shuttle, a spacecraft, etc.

[0086] The power consumption device can also be a power supply system composed of the battery disclosed in the embodiments of the present application. The power supply system can be a household energy storage cabinet, an industrial energy storage cabinet, an energy storage warehouse, etc. In this way, the influence of the external environment temperature on the performance of the power consumption device can be effectively reduced, and the use reliability of the power consumption device can be improved.

When the heat management component 100 is assembled, the first connecting portion 1122 of one heat exchange member 110 is inserted into the second connecting portion 1123 of another heat exchange member 110, thereby realizing the connection between the adjacent two heat exchange members 110 in the heat management component 100.

[0110] In some other embodiments of the present application, referring to FIGS. 5-8, the first connecting portion 1122 has a first channel 1122a in communication with the corresponding heat exchange channel 111a, and the second connecting portion 1123 has a second channel 1123a in communication with the corresponding heat exchange channel 111a. The first connecting portion 1122 is used for sealing and inserting into the second channel 1123a.

[0111] The first connecting portion 1122 is internally hollow, and the internal cavity of the first connecting portion 1122 forms the first channel 1122a.

[0117] In some embodiments, the second connecting portion 1123 can also be sealingly inserted into the first channel 1122a. For the convenience of the following description, the first connecting portion 1122 is sealingly inserted into the second channel 1123a.

[0118] In some embodiments of the present application, referring to FIGS. 8 and 9, the thermal management component 100 further comprises an elastic sealing member 113, which is used to fill between the outer wall surface of the first connecting portion 1122 and the inner wall surface of the second channel 1123a.

[0119] The elastic sealing member 113 can be a component used to fill the gap between the outer wall surface of the first connecting portion 1122 and the inner wall surface of the second channel 1123a. After the first connecting portion 1122 is inserted into the second channel 1123a, at least part of the elastic sealing member 113 is located between the outer wall surface of the first connecting portion 1122 and the inner wall surface of the second channel 1123a, so as to close the gap between the outer wall surface of the first connecting portion 1122 and the inner wall surface of the second channel 1123a, thereby achieving sealing.

[0120] In some examples, the elastic seal 113 can be made of a part of elastic material and a part of hard material, and the hard material is embedded in the elastic material to support the elastic material and improve the sealing effect of the elastic seal 113. The elastic material can be, but is not limited to, silica gel or rubber. The hard material can be metal or hard plastic.

[0121] In some examples, the elastic seal 113 can be entirely made of elastic material. The elastic seal 113 can be a sealing ring or a sealing ring.

[0122] The elastic seal 113 has elasticity, and is located between the outer wall surface of the first connecting part 1122 and the inner wall surface of the second channel 1123a. The elastic seal 113 can fill the gap between the outer wall surface of the first connecting part 1122 and the inner wall surface of the second connecting part 1123, thereby achieving the sealing connection of the first connecting part 1122 and the second connecting part 1123. The elastic seal 113 can be integrated with the second connecting part 1123, and the elastic seal 113 can also be integrated with the first connecting part 1122.

[0123] During the manufacturing process, there can be some manufacturing errors in the heat exchange element 110 or some assembly errors between adjacent two heat exchange elements 110, so that when the first connecting part 1122 is sealingly inserted into the second channel 1123a, there can be some misalignment, which can result in poor sealing effect between adjacent two heat exchange elements 110, or even difficult to be sealingly inserted together, thereby increasing the assembly difficulty of the heat management component 100.

[0124] By using the technical solution of this embodiment, the elastic seal 113 has a certain elastic deformation capability, so as to compensate for the misalignment error between the first connecting part 1122 and the second channel 1123a, so that the adjacent two heat exchange elements 110 are more easily assembled together, and it is also beneficial to improve the sealing effect of the adjacent two heat exchange elements 110.

[0125] In some other embodiments of the present application, referring to FIGS. 8 and 9, the elastic seal 113 is connected with the second connecting part 1123.

[0126] The elastic sealing member 113 is connected with the second connecting portion 1123, that is, the elastic sealing member 113 is integrated with the second connecting portion 1123. For example, the elastic sealing member 113 can be mounted in the second channel 1123a. After the first connecting portion 1122 is inserted into the second channel 1123a, the elastic sealing member 113 can be clamped between the outer wall surface of the first connecting portion 1122 and the inner wall surface of the second channel 1123a, so that the elastic sealing member 113 is deformed, thereby realizing the sealed connection of the first connecting portion 1122 and the second connecting portion 1123. Of course, before the first connecting portion 1122 and the second connecting portion 1123 are not inserted, the elastic sealing member 113 can also be located outside the second channel 1123a. The elastic sealing member 113 can enter the second channel 1123a together with the first connecting portion 1122 to realize sealing.

[0127] By adopting the technical scheme of the embodiment, the elastic sealing member 113 is connected with the second connecting portion 1123, which is simple in structure and easy to manufacture.

[0128] In some other embodiments of the present application, referring to FIGS. 8 and 9, the elastic sealing member 113 includes an elastic ring portion 1131, and the outer periphery of the elastic ring portion 1131 is connected with the second connecting portion 1123. The first connecting portion 1122 is used for being inserted into the elastic ring portion 1131 to drive the inner periphery of the elastic ring portion 1131 to move along the insertion direction of the first connecting portion 1122.

[0129] The elastic ring portion 1131 can refer to the part of the elastic sealing member 113 that moves with the first connecting portion 1122 during the process of the first connecting portion 1122 being inserted into the second channel 1123a.

Of course, before the first connecting portion 1122 and the second connecting portion 1123 are not inserted, the elastic ring portion 1131 can also be located outside the second channel 1123a, and the outer periphery of the elastic ring portion 1131 can also be fixed on the end surface of the second connecting portion 1123.

[0132] The inner hole diameter of the elastic ring part 1131 is smaller than the outer diameter of the first connecting part 1122, so that during the insertion of the first connecting part 1122 into the second channel 1123a, the first connecting part 1122 is first inserted into the inner hole of the elastic ring part 1131, and as the first connecting part 1122 continues to be inserted into the second channel 1123a, the inner periphery of the elastic ring part 1131 is also moved towards the inside of the second channel 1123a, at this time, the elastic ring part 1131 is folded and seals the gap between the outer wall surface of the first connecting part 1122 and the inner wall surface of the second channel 1123a, realizing the sealed connection of the first connecting part 1122 and the second connecting part 1123.

[0133] By adopting the technical scheme of this embodiment, after the elastic ring part 1131 is folded and inserted into the second channel 1123a along with the first connecting part 1122, the elastic sealing part 113 has a larger elastic deformation space between the outer wall surface of the first connecting part 1122 and the inner wall surface of the second channel 1123a, which can better compensate for the misalignment error of the first connecting part 1122 and the second connecting part 1123, making it easier to assemble the two adjacent heat exchange elements 110 together, and also facilitating the sealed insertion effect between the two adjacent heat exchange elements 110.

The fixed sleeve part 1132 can be made of elastic material, or it can be made of hard material, the fixed sleeve part 1132 includes elastic material and hard material, and the hard material is embedded in the elastic material to support the elastic material and the elastic ring part 1131.

[0136] The fixed sleeve portion 1132 is mounted in the second channel 1123a, the first connecting portion 1122 can be inserted into the fixed sleeve portion 1132, and the fixed sleeve portion 1132 is located between the outer wall surface of the first connecting portion 1122 and the inner wall surface of the second channel 1123a; for example, the end surface of the fixed sleeve portion 1132 can abut against the step surface between the second channel 1123a and the current collecting cavity 1121a, and the outer wall surface of the fixed sleeve portion 1132 can be in sealing connection with the inner wall surface of the second channel 1123a to achieve sealing; wherein the fixed sleeve portion 1132 can be in interference fit or clearance fit with the second channel 1123a, or the fixed sleeve portion 1132 can be fixed in the second channel 1123a by adhesive bonding.

[0137] By adopting the technical scheme of this embodiment, the fixed sleeve portion 1132 provides a mounting base for the elastic ring portion 1131, so that the elastic sealing element 113 can be more simply and conveniently fixed in the second channel 1123a.
