Furthermore, it is possible to alleviate the occurrence of a phenomenon in which the temperature inside the battery rises rapidly. Here, by blocking the cavity from both the medium inlet and the medium outlet, the cavity can prevent the entry of the fluid medium, play a role in regulating the temperature of the battery, reduce the weight of the heat management component, thereby realizing the weight reduction of the heat management component, and alleviate the phenomenon that the weight of the heat management component increases due to the entry of the fluid medium into the cavity during use. Moreover, it is possible to effectively reduce the weight of the battery having such a heat management component, improve the energy density of the battery, and is advantageous for improving the use performance of the battery.

[0006] In some embodiments, the heat management component includes a main body portion, a first bus bar member, and a second bus bar member.

A medium flow path and a cavity are provided in the main body portion. A medium inlet and a medium outlet are respectively installed on the first bus bar member and the second bus bar member, thereby communicating both ends of the medium flow path with the medium inlet and the medium outlet respectively, and the cavity does not communicate with the medium inlet and the medium outlet, thereby realizing the weight reduction of the heat management component. The structure of such a heat management component is simple and easy to manufacture.

[0008] In some embodiments, a passage is installed inside the main body portion, the passage penetrates both ends of the main body portion in the longitudinal direction of the main body portion, the heat management component further includes a sealing member, the sealing member is connected to the main body portion, and the sealing member seals both ends of the passage to form a cavity.

The structure is simple, easy to manufacture and process, and different passages can be sealed according to actual needs, thereby expanding the application range of the heat management component.

[0010] In some embodiments, the sealing member is removably connected to the main body portion.

[0011] In the above technical solution, by connecting the sealing member to the main body portion in a removable manner, the removal and replacement of the sealing member can be performed quickly, facilitating the sealing of different passages according to actual needs during use, meeting various usage requirements, while being able to perform maintenance and replacement on the sealing member, which is advantageous for extending the service life of the heat management component.

[0013] In the above technical solution, a first chamber communicating with the medium inlet is installed in the first bus bar member, and a second chamber communicating with the medium outlet is installed in the second bus bar member. As a result, the medium flow path can penetrate both ends of the main body portion and then communicate with either the first chamber or the second chamber. By realizing that the medium flow path communicates with both the medium inlet and the medium outlet, during use, it is possible to simultaneously inject a fluid medium into a plurality of medium flow paths through the medium inlet and the medium outlet, thereby improving the use efficiency.

[0014] In some embodiments, both the cavity and the medium flow path extend along the longitudinal direction of the main body portion and are arranged along the width direction of the main body portion.

[0015] In the above technical solution, both the cavity and the medium flow path extend along the longitudinal direction of the main body portion and are arranged along the width direction of the main body portion. Thereby, the processing and manufacturing of the cavity and the medium flow path become easy, and the optimization of the arrangement position of the medium flow path becomes easy. Furthermore, it is advantageous for improving the adjustment ability of the heat management component with respect to the temperature of the battery.

[0016] In some embodiments, along the width direction of the main body portion, a medium flow path is installed at the middle position of the main body portion.

[0017] In the above technical solution, the medium flow path is installed at the middle position in the width direction of the main body portion. Thereby, heat exchange can be performed on the portion where the heat inside the battery is more concentrated, which is advantageous for improving the heat management performance of the heat management component for the battery.

[0018] In some embodiments, a plurality of medium flow paths and a plurality of cavities are installed in the heat management component, and along the width direction of the main body portion, the cavities and the medium flow paths are alternately arranged.

[0024] In some embodiments, the medium outlet of one heat management component communicates with the medium inlet of another heat management component.

[0025] In the above technical solution, the medium outlet of one of the plurality of heat management components is communicated with the medium inlet of another heat management component to realize the series structure of the plurality of heat management components, thereby facilitating assembly and processing, and facilitating the injection of the fluid medium into the medium flow paths of the plurality of heat management components during use.

[0026] In some embodiments, a plurality of medium flow paths are provided in the heat management component. Along the flow direction of the fluid medium in the medium flow paths of the plurality of heat management components, among two adjacent heat management components, the number of medium flow paths of the heat management component downstream is larger than the number of medium flow paths of the heat management component upstream.

[0027] In the above technical solution, in the flow direction of the fluid medium, the number of medium flow paths of the heat management component downstream is larger than the number of medium flow paths of the heat management component upstream, which is advantageous for improving the heat exchange capacity of the heat management component downstream, thereby ensuring the balance of the heat exchange capacities of the plurality of heat management components in the heat management system and improving the heat management capacity of the entire heat management system. Furthermore, the occurrence of local temperature rise phenomena inside the battery can be effectively alleviated.

[0028] In some embodiments, the medium inlets of the plurality of heat management components communicate with each other, and the medium outlets of the plurality of heat management components communicate with each other.

[0029] In the above technical solution, the medium inlets of the plurality of heat management components communicate with each other, and the medium outlets of the plurality of heat management components communicate with each other to realize the parallel structure of the plurality of heat management components. On the one hand, the function of simultaneously injecting the fluid medium into the medium flow paths of the plurality of heat management components can be realized.

It should be understood that the sizes such as the thickness, length, and width of various members in the Examples of this application shown in the drawings, and the overall size such as the thickness, length, and width of the integrated device are illustrative explanations and should not constitute any limitation to this application.

[0041] "Plurality" as used in this application refers to two or more (including two).

[0042] In this application, the battery cell may include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery, a magnesium-ion battery, etc., and the embodiments of this application do not limit this. The battery cell may have a cylindrical shape, a flat shape, a cuboid shape, or other shapes, and the embodiments of this application do not limit this either. Generally, battery cells are divided into three types: cylindrical battery cells, square battery cells, and pouch battery cells in a packaging manner, and the embodiments of this application do not limit this either.

[0043] The battery referred to in the embodiments of this application refers to a single physical module including one or more battery cells to provide a higher voltage and capacity. For example, the battery referred to in this application may include a battery module, a battery pack, etc. Generally, a battery includes a housing for packaging one or more battery cells or a plurality of battery modules. The housing can avoid the influence of liquid or other foreign substances on the charging or discharging of the battery cell.

[0044] The battery cell includes a housing, an electrode assembly, and an electrolyte. The housing is used to accommodate the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode plate, a negative electrode plate, and a separator. The battery cell mainly operates by the movement of metal ions between the positive electrode plate and the negative electrode plate.

[0045] In recent years, new energy vehicles have developed by leaps and bounds. In the field of electric vehicles, as a power source for electric vehicles, the power battery plays an irreplaceable important role. The battery is composed of a housing and a plurality of battery cells accommodated in the housing. Here, as a core component of new energy vehicles, the battery has high requirements in terms of safety and cycle life.

[0046] The inventor has found that in general power batteries, in order to equip the battery with sufficient power, it is often installed in a way that arranges a plurality of battery cells inside the battery housing. However, in the process of using the battery cells for continuous charge and discharge, a large amount of heat is generated, which causes the internal temperature of the battery to rise. Moreover, the structure of stacking and installing a plurality of battery cells exacerbates the occurrence of such a phenomenon, further seriously affecting the usage performance and service life of the battery, posing a major safety concern during the use of the battery, and even compromising the usage safety of consumers. Therefore, in the prior art, generally a water-cooling plate is installed inside the battery. The water-cooling plate is on one side of a plurality of battery cells, and a passage for the cooling medium to flow is formed inside the water-cooling plate, thereby playing a role in cooling the battery cells and reducing the temperature. However, the water-cooling plate with such a structure has a large self-weight, and the weight of the water-cooling plate further increases after injecting the cooling liquid. The increase in the weight of such a water-cooling plate battery reduces the overall energy density of the battery, deteriorates the usage performance of the battery, and is disadvantageous for popularization and use.

[0047] Based on the above considerations, in order to solve the problem that the weight of the conventional battery is large and deteriorates the usage performance of the battery, the inventor has intensively studied and designed a heat management component as a result. The heat management component is provided with a media inlet, a media outlet, and a media flow path. The media flow path is inside the heat management component, and the media flow path communicates the media inlet and the media outlet. The media flow path is used to accommodate a fluid medium and adjust the temperature of the battery. Here, a cavity that is blocked from both the media inlet and the media outlet is further installed inside the heat management component.

[0048] In a heat management component with such a structure, a medium inlet, a medium outlet, a cavity, and a medium flow path are provided in the heat management component, and the medium flow path communicates with both the medium inlet and the medium outlet, so as to accommodate a fluid medium and play a role in regulating the temperature of the battery. Furthermore, the occurrence of the phenomenon that the temperature inside the battery rises rapidly can be alleviated. Here, by blocking the cavity from both the medium inlet and the medium outlet, the cavity can prevent the entry of the fluid medium, play a role in regulating the temperature of the battery, reduce the weight of the heat management component, thereby realizing the weight reduction of the heat management component, and alleviating the phenomenon that the weight of the heat management component increases due to the entry of the fluid medium into the cavity during use. Moreover, the weight of the battery having such a heat management component can be effectively reduced, which is advantageous for improving the energy density of the battery and the use performance of the battery.

[0049] The heat management component disclosed in the embodiments of the present application may be used in power-consuming devices such as vehicles, ships, or aircraft, but is not limited thereto. The power supply system of this power-consuming device can be configured using the heat management system, battery, etc. disclosed in the present application. In this way, it is advantageous for reducing the overall weight of the battery and improving the energy density and use performance of the entire battery.

[0050] The embodiments of the present application provide a power-consuming device that uses a battery as a power source. The power-consuming device may be, but is not limited to, a mobile phone, a tablet, a notebook computer, an electric toy, an electric tool, a battery vehicle, an electric vehicle, a steamship, an aircraft, etc. Here, the electric toy may include a stationary or mobile electric toy, for example, a game console, an electric vehicle toy, an electric steamship toy, an electric airplane toy, etc., and the aircraft may include an airplane, a rocket, a space shuttle, a spaceship, etc.

[0051] For the convenience of description, the following embodiments will be described by taking the power-consuming device of an embodiment of the present application as the vehicle 1000 as an example.

[0052] Referring to FIG. 1, FIG. 1 is a schematic structural diagram of a vehicle 1000 according to some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle, 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 the operating power source of 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, it is used for the starting, navigation, and operating power requirements during driving of the vehicle 1000.

[0053] In some embodiments of the present application, the battery 100 can not only be used as the operating power source of the vehicle 1000, but also be used as the driving power source of the vehicle 1000 to provide driving power to the vehicle 1000 instead of or partially instead of fuel oil or natural gas.

[0054] Referring to FIG. 2, FIG. 2 is an exploded view of the structure of the battery 100 according to some embodiments of the present application. The battery 100 includes a housing 10 and a plurality of battery cells 20, and the battery cells 20 are accommodated in the housing 10. Here, the housing 10 is used to provide an assembly space for the battery cells 20, and the housing 10 can adopt various structures. In some embodiments, the housing 10 may include a first box body 11 and a second box body 12. The first box body 11 and the second box body 12 are covered with each other, and together with the first box body 11 and the second box body 12, an assembly space for accommodating the battery cells 20 is defined. The second box body 12 may have a hollow structure with one end open, the first box body 11 may have a plate-like structure, and the first box body 11 is covered on the open side of the second box body 12 to define an assembly space together with the first box body 11 and the second box body 12. The first box body 11 and the second box body 12 may both have a hollow structure with one side open, and the open side of the first box body 11 is covered on the open side of the second box body 12. Of course, the housing 10 formed by the first box body 11 and the second box body 12 may have various shapes, such as a cylindrical body or a rectangular parallelepiped, etc.

[0055] In the battery 100, the plurality of battery cells 20 may be connected in series, in parallel, or in series-parallel. Series-parallel connection means that the plurality of battery cells 20 include both series connection and parallel connection. The plurality of battery cells 20 may be directly connected in series, in parallel, or in series-parallel first, and then the whole formed by the plurality of battery cells 20 may be accommodated in the housing 10. Of course, the battery 100 may first connect the plurality of battery cells 20 in series, in parallel, or in series-parallel to form the form of a battery module, and then connect the plurality of battery modules in series, in parallel, or in series-parallel to form a whole, and accommodate it in the housing 10. The battery 100 may further include other structures. For example, this battery 100 may further include a bus bar component for realizing the electrical connection between the plurality of battery cells 20.

[0056] Optionally, the battery 100 may further include a thermal management system 30. The thermal management system 30 is installed within the housing 10 and is used to manage the temperature of the battery cells 20 to play a role in cooling and lowering the temperature of the battery cells 20.

[0057] Referring to FIG. 2 and further to FIG. 3, FIG. 3 is a schematic connection diagram of the thermal management system 30 and the battery cells 20 according to some embodiments of the present application. The battery 100 includes a plurality of rows of battery cells 20. The plurality of rows of battery cells 20 are arranged along the width direction of the battery cells 20, and each row of battery cells 20 includes a plurality of battery cells 20 arranged along the longitudinal direction of the battery cells 20.

[0058] Here, each battery cell 20 may be a secondary battery or a primary battery, and may be, but is not limited to, a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery. The battery cell 20 may exhibit a cylindrical shape, a flat shape, a cuboid shape, or other shapes. Exemplarily, in FIG. 3, the shape of the battery cell 20 is a cuboid.

[0059] In some embodiments, the thermal management system 30 may include a plurality of thermal management components 31. Along the width direction of the battery cells 20, one thermal management component 31 is installed between two adjacent rows of battery cells 20. The thermal management component 31 is configured to exchange heat with the battery cells 20 to manage the temperature of the battery cells 20.

[0060] According to some embodiments of the present application, referring to FIG. 3 and further FIG. 4, FIG. 4 is a schematic structural diagram of a heat management component 31 according to some embodiments of the present application. The present application provides a heat management component 31, and a medium inlet 311, a medium outlet 312, and a medium flow path 313 (not shown in FIG. 4) are provided in the heat management component 31. The medium flow path 313 is inside the heat management component 31. The medium flow path 313 communicates the medium inlet 311 and the medium outlet 312, and the medium flow path 313 contains a fluid medium and is used to adjust the temperature of the battery 100. Here, a cavity 314 (not shown in FIG. 4) that is blocked from both the medium inlet 311 and the medium outlet 312 is provided inside the heat management component 31.

[0061] Here, the medium inlet 311 and the medium outlet 312 are respectively installed at both ends of the heat management component 31, and both the medium flow path 313 and the cavity 314 are installed inside the heat management component 31. The medium flow path 313 communicates the medium inlet 311 and the medium outlet 312, that is, both ends of the medium flow path 313 communicate with the medium inlet 311 and the medium outlet 312 respectively, enabling the inflow or outflow of the fluid medium into the medium flow path 313. The cavity 314 is blocked from both the medium inlet 311 and the medium outlet 312, that is, no communication relationship is formed between the cavity 314 and either the medium inlet 311 or the medium outlet 312, so that the fluid medium cannot enter the cavity 314.

[0062] The medium flow path 313 is used to contain a fluid medium, that is, when the fluid medium flows through the medium flow path 313, it can exchange heat with the inside of the battery 100 through the heat management component 31, thereby realizing the function of managing the internal temperature of the battery 100 by the heat management component 31. Exemplarily, the fluid medium may be a gas, such as air or hydrogen gas, etc., or the fluid medium may be a liquid, such as water, an aqueous salt solution or liquid nitrogen, etc.

[0063] It should be noted that the cavity 314 installed inside the heat management component 31 may be one or a plurality. Similarly, the medium flow path 313 installed inside the heat management component 31 may be one or a plurality. When there are a plurality of medium flow paths 313, each medium flow path 313 communicates the medium inlet 311 and the medium outlet 312, that is, both ends of the plurality of medium flow paths 313 communicate with the medium inlet 311 and the medium outlet 312 respectively. Exemplarily, in the embodiments of the present application, both the medium flow path 313 and the cavity 314 installed inside the heat management component 31 are plural.

[0064] The heat management component 31 is provided with a medium inlet 311, a medium outlet 312, a cavity 314, and a medium flow path 313, and the medium flow path 313 communicates with both the medium inlet 311 and the medium outlet 312, so as to accommodate a fluid medium and play a role in adjusting the temperature of the battery 100. Furthermore, the occurrence of the phenomenon that the temperature inside the battery 100 rises sharply can be alleviated. Here, by blocking the cavity 314 from both the medium inlet 311 and the medium outlet 312, the cavity 314 can prevent the entry of the fluid medium, play a role in adjusting the temperature of the battery 100, and reduce the weight of the heat management component 31. Thereby, the weight reduction of the heat management component 31 can be realized, and the phenomenon that the weight of the heat management component 31 increases due to the entry of the fluid medium into the cavity 314 during use can be alleviated. Furthermore, the weight of the battery 100 having such a heat management component 31 can be effectively reduced, which is advantageous for improving the energy density of the battery 100 and improving the use performance of the battery 100.

[0065] According to some embodiments of the present application, referring to FIG. 4 and further FIG. 5, FIG. 5 is a cross-sectional view of the main body 315 of the heat management component 31 according to some embodiments of the present application. The heat management component 31 includes a main body 315, a first busbar member 316, and a second busbar member 317. A media flow path 313 and a cavity 314 are provided in the main body 315.

[0066] Here, both the media flow path 313 and the cavity 314 are installed inside the main body 315. Exemplarily, in FIG. 5, both the media flow path 313 and the cavity 314 extend along the longitudinal direction X of the main body, and both ends of the media flow path 313 penetrate through both ends of the main body 315 respectively, so that the media flow path 313 can communicate with the media inlet 311 of the first busbar member 316 and the media outlet 312 of the second busbar member 317.

[0067] It should be noted that the main body 315, the first busbar member 316, and the second busbar member 317 may have an integrated structure or a separate structure. When the main body 315, the first busbar member 316, and the second busbar member 317 have an integrated structure, the main body 315, the first busbar member 316, and the second busbar member 317 may be manufactured by adopting a casting or injection molding process. When the main body 315, the first busbar member 316, and the second busbar member 317 have a separate structure, the first busbar member 316 and the second busbar member 317 may be connected to both ends of the main body 315 by adopting methods such as screwing with bolts, fitting, or adhesion.

[0068] In the heat management component 31, a main body portion 315, a first bus bar member 316 and a second bus bar member 317 connected to both ends of the main body portion 315 in the longitudinal direction X of the main body portion are installed. A medium flow path 313 and a cavity 314 are installed in the main body portion 315. A medium inlet 311 and a medium outlet 312 are installed in the first bus bar member 316 and the second bus bar member 317 respectively, thereby communicating both ends of the medium flow path 313 with the medium inlet 311 and the medium outlet 312 respectively. And the cavity 314 is not communicated with the medium inlet 311 and the medium outlet 312, thereby realizing weight reduction of the heat management component 31. The structure of such a heat management component 31 is simple and easy to manufacture.

[0069] According to some embodiments of the present application, referring to FIGS. 4, 5, and further FIG. 6, FIG. 6 is a cross-sectional view of the main body portion 315 of the heat management component 31 according to some embodiments of the present application. A passage 3151 is installed inside the main body portion 315, and the passage 3151 penetrates both ends of the main body portion 315 in the longitudinal direction X of the main body portion. The heat management component 31 further includes a sealing member 318. The sealing member 318 is connected to the main body portion 315, and the sealing member 318 seals both ends of the passage 3151 to form the cavity 314.

[0070] Here, along the longitudinal direction X of the main body portion, sealing members 318 are installed at both ends of the main body portion 315 through which the passage 3151 penetrates. By sealing both ends of the passage 3151 with the sealing members 318, a sealed cavity 314 can be formed, thereby realizing that the cavity 314 is blocked from both the medium inlet 311 and the medium outlet 312.

[0071] Exemplarily, the sealing member 318 may be a metal piece, a rubber stopper, a silicon stopper, etc. During actual production, different sealing members 318 can be adopted according to the size of the passage 3151. For example, when the passage 3151 is large, it may be connected to one end of the main body 315 by means of metal piece welding to seal the passage 3151, or a rubber stopper or a silicon stopper may be adopted to seal the passage 3151. When the passage 3151 is small, there is a problem that it is difficult to weld the metal piece, and a rubber stopper or a silicon stopper may be adopted and fitted into the passage 3151 to achieve the sealing effect on the passage 3151.

[0072] In some embodiments, as shown in FIGS. 5 and 6, the sealing member 318 is removably connected to the main body 315. By connecting the sealing member 318 to the main body 315 in a removable manner, the removal and replacement of the sealing member 318 can be quickly performed, facilitating the sealing of different passages 3151 according to actual needs during use and meeting various usage requirements. At the same time, maintenance and replacement of the sealing member 318 can be carried out, which is advantageous for extending the service life of the thermal management component 31.

[0073] Exemplarily, the sealing member 318 is fitted to one end of the passage 3151 to achieve the sealing of the passage 3151. Of course, in other embodiments, the sealing member 318 may be removably connected to the main body 315 by adopting methods such as screwing or engaging connection with bolts.

[0074] It should be noted that in FIG. 6, the cavity 314 is a sealed structure formed by sealing the passage 3151 inside the main body 315 with the sealing member 318. In other embodiments, as shown in FIG. 7, FIG. 7 is a cross-sectional view of the main body 315 of the thermal management component 31 according to some embodiments of the present application, and the cavity 314 may be a structure formed integrally with the main body 315, that is, the cavity 314 is a structure with a cavity inside formed by processes such as casting or press forming of the main body 315, that is, the sealing member 318 and the main body 315 are of an integral structure.

[0075] Inside the main body portion 315 of the heat management component 31, a passage 3151 is formed that penetrates both ends of the main body portion 315 in the longitudinal direction X of the main body portion. A sealing member 318 is installed on the main body portion 315, and by sealing both ends of the passage 3151 with the sealing member 318, a cavity 314 that is blocked from both the medium inlet 311 and the medium outlet 312 is formed. The structure is simple, easy to manufacture and process, and different passages 3151 can be sealed according to actual needs, thereby expanding the application range of the heat management component 31.

[0076] According to some embodiments of the present application, as shown in FIGS. 4 and 5, inside the first bus bar member 316, a first chamber communicating with the medium inlet 311 is formed, and inside the second bus bar member 317, a second chamber communicating with the medium outlet 312 is formed. The medium flow path 313 penetrates both ends of the main body portion 315 in the longitudinal direction X of the main body portion and communicates with the first chamber and the second chamber.

[0077] Here, inside the first bus bar member 316, a first chamber communicating with the medium inlet 311 is formed, that is, a first chamber is formed inside the first bus bar member 316, and the medium inlet 311 penetrates the chamber wall of the first chamber. When the first bus bar member 316 is attached to one end of the main body portion 315, the medium flow path 313 that penetrates one end of the main body portion 315 can communicate with the first chamber inside the first bus bar member 316, thereby enabling all the plurality of medium flow paths 313 to communicate with the first chamber of the first bus bar member 316 and realizing that all the plurality of medium flow paths 313 communicate with the medium inlet 311.

[0078] Similarly, a second chamber communicating with the media outlet 312 is formed inside the second bus bar member 317, that is, a second chamber is formed inside the second bus bar member 317, and the media outlet 312 penetrates the chamber wall of the second chamber. When the second bus bar member 317 is attached to one end of the main body portion 315, the media flow path 313 penetrating one end of the main body portion 315 can communicate with the second chamber inside the second bus bar member 317, whereby all of the plurality of media flow paths 313 can be made to communicate with each other with the second chamber of the second bus bar member 317, and all of the plurality of media flow paths 313 can be made to communicate with the media outlet 312.

[0079] It should be noted that the cavity 314 does not communicate with either the first chamber of the first bus bar member 316 or the second chamber of the second bus bar member 317, whereby the cavity 314 is blocked from both the media inlet 311 and the media outlet 312.

[0080] A first chamber communicating with the media inlet 311 is installed in the first bus bar member 316, and a second chamber communicating with the media outlet 312 is installed in the second bus bar member 317, whereby the media flow path 313 can communicate with both the first chamber and the second chamber after penetrating both ends of the main body portion 315, and by realizing that the media flow path 313 communicates with both the media inlet 311 and the media outlet 312, during use, a fluid medium can be simultaneously injected into the plurality of media flow paths 313 via the media inlet 311 and the media outlet 312, and the use efficiency can be improved.

[0081] According to some embodiments of the present application, as shown in FIGS. 5 and 6, both the cavity 314 and the media flow path 313 extend along the longitudinal direction X of the main body portion and are arranged along the width direction Y of the main body portion.

[0082] Here, a plurality of medium flow paths 313 and a plurality of cavities 314 are provided in the heat management component 31. Both the cavities 314 and the medium flow paths 313 extend along the longitudinal direction X of the main body portion, and the plurality of cavities 314 and the plurality of medium flow paths 313 are both arranged along the width direction Y of the main body portion. The arrangement methods of the plurality of cavities 314 and the plurality of medium flow paths 313 may be various. For example, the cavities 314 and the medium flow paths 313 may be arranged alternately. Along the width direction Y of the main body portion, the plurality of cavities 314 may be on one side of the plurality of medium flow paths 313. Along the width direction Y of the main body portion, a plurality of cavities 314 may be installed at the middle position of the main body portion 315, and medium flow paths 313 may be installed on either side of the plurality of cavities 314. Exemplarily, in FIG. 5, along the width direction Y of the main body portion, two medium flow paths 313 are installed at the middle position of the main body portion 315, and three cavities 314 are installed on each side of the two medium flow paths 313, and one medium flow path 313 is installed at both ends of the main body portion 315.

[0083] Both the cavities 314 and the medium flow paths 313 extend along the longitudinal direction X of the main body portion and are arranged along the width direction Y of the main body portion, thereby facilitating the processing and manufacturing of the cavities 314 and the medium flow paths 313, facilitating the optimization of the arrangement positions of the medium flow paths 313, and further being advantageous for improving the adjustment ability of the heat management component 31 with respect to the temperature of the battery 100.

[0084] According to some embodiments of the present application, continuing to refer to FIGS. 5 and 6, along the width direction Y of the main body portion, a medium flow path 313 is installed at the middle position of the main body portion 315.

[0085] Here, a medium flow path 313 is installed at the intermediate position of the main body 315. When there is only one medium flow path 313, the medium flow path 313 is installed at the intermediate position of the main body 315. When there are multiple medium flow paths 313, at least some of the multiple medium flow paths 313 are at the intermediate position of the main body 315 in the width direction Y of the main body. Exemplarily, in FIGS. 5 and 6, along the width direction Y of the main body, two medium flow paths 313 are installed at the intermediate position of the main body 315. Of course, in other embodiments, along the width direction Y of the main body, one, three, four or the like of medium flow paths 313 may be installed at the intermediate position of the main body 315.

[0086] The main body 315 has a medium flow path 313 installed at its intermediate position in the width direction, whereby heat exchange can be performed on the location where the heat inside the battery 100 is more concentrated, which is advantageous for improving the heat management performance of the heat management component 31 for the battery 100.

[0087] According to some embodiments of the present application, referring to FIG. 8, FIG. 8 is a cross-sectional view of the main body 315 of the heat management component 31 according to some further other embodiments of the present application. A plurality of medium flow paths 313 and a plurality of cavities 314 are installed in the heat management component 31, and along the width direction Y of the main body, the cavities 314 and the medium flow paths 313 are arranged alternately.

[0088] Here, the cavities 314 and the medium flow paths 313 are arranged alternately, that is, the cavities 314 and the medium flow paths 313 are sequentially arranged alternately along the width direction Y of the main body. That is, along the width direction Y of the main body, a cavity 314 is installed between two adjacent medium flow paths 313, and a medium flow path 313 is installed between two adjacent cavities 314.

[0089] The cavity 314 and the medium flow path 313 are alternately arranged along the width direction Y of the main body portion. That is, both the cavity 314 and the medium flow path 313 are plural, and by alternately arranging the cavity 314 and the medium flow path 313 to realize the dispersed arrangement of the medium flow path 313 along the width direction Y of the main body portion, the phenomenon that the heat exchange capacity of the heat management component 31 is unbalanced due to the concentration of the medium flow path 313 can be effectively reduced, and it is also advantageous for improving the use performance of the heat management component 31.

[0090] According to some embodiments of the present application, as shown in FIG. 6, along the thickness direction Z of the main body portion, the main body portion 315 has two opposing side surfaces 3152. The area of one side surface 3152 is S1, the total projected area of the medium flow path 313 on the side surface 3152 is S2, and S2 / S1≥0.2.

[0091] Here, the area of one side surface 3152 is S1, the total projected area of the medium flow path 313 on the side surface 3152 is S2, and S2 / S1≥0.2, that is, the total occupied area of the plurality of medium flow paths 313 on the side surface 3152 of the main body portion 315 is 20% or more.

[0092] By making the occupied area of the plurality of medium flow paths 313 on the side surface 3152 of the main body portion 315 20% or more, the phenomenon that the heat exchange capacity is poor due to the too small occupied area of the medium flow path 313 can be reduced, and the heat exchange performance of the heat management component 31 can be further guaranteed.

[0093] According to some embodiments of the present application, as shown in FIGS. 3 and 4, the embodiments of the present application further provide a heat management system 30, and the heat management system 30 includes a plurality of heat management components 31 in any one of the above solutions.

[0094] Here, the medium flow paths 313 of the plurality of heat management components 31 may be connected in series with each other. That is, the medium inlet 311 of one heat management component 31 communicates with the medium outlet 312 of another heat management component 31. Of course, the medium flow paths 313 of the plurality of heat management components 31 may also be connected in parallel with each other. That is, the medium inlets 311 of the plurality of heat management components 31 communicate with each other, and the medium outlets 312 of the plurality of heat management components 31 communicate with each other.

[0095] When a plurality of heat management components 31 are installed in the heat management system 30, in the battery 100 having such a heat management system 30, it is advantageous to improve the heat management ability of the heat management system 30 with respect to the battery 100 and reduce the safety concerns caused by the internal temperature rise of the battery 100.

[0096] According to some embodiments of the present application, as shown in FIGS. 3 and 4, the medium outlet 312 of one heat management component 31 communicates with the medium inlet 311 of another heat management component 31.

[0097] Here, the structure in which the medium outlet 312 of one heat management component 31 communicates with the medium inlet 311 of another heat management component 31 may be various. The medium outlet 312 of one heat management component 31 may be connected to the medium inlet 311 of another heat management component 31, or may communicate through other components, such as a communication pipeline, thereby realizing a series structure of the plurality of heat management components 31.

[0098] By communicating the medium outlet 312 of one heat management component 31 among the plurality of heat management components 31 with the medium inlet 311 of another heat management component 31 to realize a series structure of the plurality of heat management components 31, assembly and processing can be facilitated, and the injection of the fluid medium into the medium flow paths 313 of the plurality of heat management components 31 during use can be facilitated.

[0099] According to some embodiments of the present application, a plurality of media channels 313 are provided in the heat management component 31. Along the flow direction of the fluid medium in the media channels 313 of the plurality of heat management components 31, among two adjacent heat management components 31, the number of media channels 313 of the downstream heat management component 31 is larger than the number of media channels 313 of the upstream heat management component 31.

[0100] Here, the flow direction of the fluid medium in the media channels 313 of the plurality of heat management components 31 is the direction when the fluid medium flows through the media channels 313 of the plurality of heat management components 31.

[0101] Among two adjacent heat management components 31, the number of media channels 313 of the downstream heat management component 31 is larger than the number of media channels 313 of the upstream heat management component 31. That is, in the flow direction of the fluid medium, among two adjacent heat management components 31, the heat management component 31 through which the fluid medium first flows is the upstream heat management component 31, and the heat management component 31 through which the fluid medium then flows is the downstream heat management component 31. That is, the fluid medium flows from the media channels 313 of the upstream heat management component 31 to the media channels 313 of the downstream heat management component 31.

[0102] By making the number of media channels 313 of the downstream heat management component 31 larger than the number of media channels 313 of the upstream heat management component 31, it is advantageous to improve the heat exchange capacity of the downstream heat management component 31, thereby ensuring the balance of the heat exchange capacities of the plurality of heat management components 31 in the heat management system 30 and improving the overall heat management capacity of the heat management system 30. Furthermore, the occurrence of local temperature rise phenomena inside the battery 100 can be effectively alleviated.

[0103] In some embodiments, the media inlets 311 of the plurality of heat management components 31 communicate with each other, and the media outlets 312 of the plurality of heat management components 31 communicate with each other.

[0104] Here, the medium inlets 311 of the plurality of heat management components 31 may be directly communicated with each other, or may be communicated with each other via other components, such as a communication pipeline, etc. Similarly, the medium outlets 312 of the plurality of heat management components 31 are also the same, thereby realizing a parallel structure of the plurality of heat management components 31.

[0105] By communicating the medium inlets 311 of the plurality of heat management components 31 with each other and communicating the medium outlets 312 of the plurality of heat management components 31 with each other to realize a parallel structure of the plurality of heat management components 31, while realizing the function of simultaneously injecting a fluid medium into the medium flow paths 313 of the plurality of heat management components 31, the balance of the heat exchange capabilities of each heat management component 31 can be effectively guaranteed, and further, the occurrence of local temperature rise phenomena inside the battery 100 can be effectively alleviated.

[0109] Here, the first side surface 21 abutting against the heat management component 31 may mean that the first side surface 21 directly abuts against the heat management component 31, that is, the surface with the largest area among the outer surfaces of the battery cell 20 may be directly bonded onto the heat management component 31. Of course, in some embodiments, the first side surface 21 may indirectly abut against the heat management component 31, that is, the surface with the largest area among the outer surfaces of the battery cell 20 is bonded onto the heat management component 31 via a heat conduction member, such as a heat conduction paste.

[0110] It should be noted that the battery cell 20 has a cuboid structure, and the first side surface 21 is the surface with the largest area among the outer surfaces of the battery cell 20. That is, the first side surface 21 is the outer surface of one side of the battery cell 20 in the width direction of the battery cell 20. That is, the heat management component 31 of the heat management system 30 is installed between two adjacent rows of battery cells 20 along the width direction of the battery cell 20, and the main body portion 315 of the heat management component 31 abuts against the first side surface 21 of the battery cell 20 to realize heat exchange between the battery cell 20 and the heat management component 31.

[0111] Here, the longitudinal direction X of the main body portion coincides with the longitudinal direction of the battery cell 20, and the thickness direction Z of the main body portion coincides with the width direction of the battery cell 20.

[0112] The heat management component 31 of the heat management system 30 abuts against the first side surface 21 of the battery cell 20. That is, the heat management component 31 of the heat management system 30 is installed on the side with the largest surface area of the battery cell 20, thereby ensuring that the battery cell 20 and the heat management component 31 have a sufficient heat exchange area, which is beneficial to improving the heat management ability of the heat management component 31 for the battery cell 20, and can further effectively reduce the safety concerns caused by the temperature rise during the use of the battery 100.
