Description

Technical Field

[0001] The utility model relates to the technical field of energy storage equipment, and in particular to a heat dissipation component and energy storage equipment. Background Art

[0002] At present, energy storage equipment generates a large amount of heat during operation. In related technologies, air cooling or liquid cooling is usually used for heat dissipation. Air cooling requires additional fans and air ducts, and it also makes a lot of noise during operation. Liquid cooling requires a cold source, and the system is more complicated. Utility Model Content

[0003] The utility model aims to at least solve the technical problem existing in the prior art or related art that when dissipating heat for energy storage equipment, additional space needs to be occupied and the heat dissipation efficiency in a small space is low.

[0004] In view of this, an embodiment of a first aspect of the present invention provides a heat dissipation assembly.

[0005] An embodiment of the second aspect of the utility model provides an energy storage device.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the utility model provides a heat dissipation component, which is used to dissipate heat from a heat generating element. The heat dissipation component includes: a hydrophilic membrane component; a fin heat dissipation component, including a connected heat conducting portion and a fin portion, the heat conducting portion is used to receive heat from the heat generating element, and at least a portion of the hydrophilic membrane component is at least arranged on at least a portion of the outer surface of the fin portion.

[0007] According to the heat dissipation assembly proposed by the utility model, it includes a hydrophilic membrane assembly and a fin heat dissipation assembly. The hydrophilic membrane assembly and the fin heat dissipation assembly are combined to further improve the heat dissipation effect of the heat dissipation assembly on the basis of fin heat dissipation, and realize efficient, stable and noiseless heat dissipation, which is suitable for equipment that requires long-term reliable operation and low maintenance cost. Specifically, the hydrophilic membrane assembly can reduce the temperature of the heating element by absorbing moisture in the air and dissipating heat by phase change. The fin heat dissipation assembly includes a heat conduction part and a fin part, wherein the heat conduction part is in direct or indirect contact with the heating element so as to receive the heat generated by the heating element, so as to achieve heat dissipation under the joint action of the fin part and the hydrophilic membrane assembly, and is usually made of a high thermal conductivity material, such as copper or aluminum. The fin part is connected to the heat conduction part, and is used to expand the heat conduction area and improve the heat dissipation efficiency, and is usually a multi-piece thin metal sheet structure.

[0008] The heat conducting part will quickly conduct heat from the heating element to the fin part, which will increase the heat dissipation surface area and accelerate the heat dissipation. Combined with the hydrophilic membrane component, the heat dissipation efficiency is further improved.

[0009] It should be added that part or all of the hydrophilic membrane assembly can be arranged on the fin part, and of course can also be arranged at the position of the heat conduction part, and the specific position can be arranged on the outer surface or inner surface of the fin part.

[0010] Furthermore, the hydrophilic membrane assembly can be provided on a part of the outer surface or the entire outer surface of the fin portion according to requirements.

[0011] The heat conducting part is in direct or indirect contact with the heating element, and can quickly transfer the heat to the fin part, and then dissipate the heat through the hydrophilic membrane assembly, which continuously absorbs moisture in the air. When the heat is transferred to the hydrophilic membrane assembly, the water evaporates and takes away a large amount of latent heat. Finally, the evaporated water vapor escapes into the air through the hydrophilic membrane assembly. When the equipment stops working, the hydrophilic membrane assembly continues to absorb moisture in the air, replenishes the stored water, and prepares for the next heat dissipation cycle.

[0012] In some technical solutions, optionally, the fin portion includes a plurality of fins arranged at intervals, and the hydrophilic membrane assembly is arranged on at least one side of the fin.

[0013] In this technical solution, the fin portion includes a plurality of fins, and adjacent fins do not contact each other but have gaps therebetween, thereby providing a larger heat dissipation surface area while maintaining good air circulation, thereby enhancing heat conduction and dissipation efficiency, and ensuring that heat can be quickly transferred from the heating element to the fin surface for heat dissipation.

[0014] By fixing the hydrophilic membrane assembly on at least one side of the fin, the hydrophilic membrane is in direct contact with the surface of the fin, optimizing the heat conduction path, and the heat can be quickly transferred to the hydrophilic membrane, so that the hydrophilic membrane absorbs heat and evaporates water, thereby taking away the heat, optimizing the contact area between the hydrophilic membrane and the fin, ensuring that heat can be quickly transferred to the hydrophilic membrane, achieving efficient heat dissipation and water evaporation, further improving the overall heat dissipation performance, ensuring that the equipment maintains a low temperature while operating efficiently, and improving the reliability and service life of the equipment.

[0015] By using fins set at intervals, heat can be quickly transferred and dissipated through a larger surface area, avoiding heat accumulation, improving heat dissipation efficiency, maintaining air circulation, avoiding heat accumulation between fins, and allowing the entire heat dissipation structure to exchange heat more efficiently.

[0016] In some technical solutions, optionally, the hydrophilic membrane assembly is arranged on a side of the heat-conducting portion away from the heat-generating element, and the heat-conducting portion is in contact with the heat-generating element.

[0017] In this technical solution, the hydrophilic membrane assembly is placed on the side of the heat conductive part away from the heat source so that it does not directly contact the heat generating element. Instead, the heat generated by the heat generating element in direct contact with the hydrophilic membrane assembly is transferred to the hydrophilic membrane assembly through the heat conductive part, thereby achieving heat dissipation and ensuring that the hydrophilic membrane assembly can operate in a relatively stable temperature environment, avoiding the direct impact of high temperature on the hydrophilic membrane, thereby improving its service life and heat dissipation efficiency.

[0018] It can be understood that in this solution, the hydrophilic membrane component can maintain good performance in a high temperature environment, avoiding material aging or performance degradation caused by direct contact with high temperature. The hydrophilic membrane component is far away from the heating element, which reduces the impact of thermal stress on it, enhances the overall reliability of the system, ensures that the heat dissipation system can maintain stable performance during long-term use, and prolongs the service life of the equipment.

[0019] In some technical solutions, optionally, it includes: an insulating heat-conducting medium, which is arranged between the heat-conducting part and the heat-generating element, and the projection of the heat-generating element on the insulating heat-conducting medium is located in the insulating heat-conducting medium.

[0020] In this technical solution, an insulating heat-conducting medium is arranged between the heat-conducting part and the heating element, and the insulating heat-conducting medium covers the heating element, so that the heat generated by the heating element can be transferred to the heat-conducting part through the insulating heat-conducting medium, and then transferred to the hydrophilic membrane assembly through the fin part, thereby achieving efficient heat dissipation.

[0021] It can be understood that the projection of the heating element on the insulating heat-conducting medium is within the insulating heat-conducting medium, which can increase the contact area between the heating element and the insulating heat-conducting medium and improve the heat conduction efficiency.

[0022] In some technical solutions, optionally, the hydrophilic membrane assembly includes: a waterproof and breathable membrane, part of which is in contact with the fin heat dissipation assembly, and a cavity is formed between part of the waterproof and breathable membrane and the fin heat dissipation assembly; and a hydrophilic membrane, which is arranged in the cavity.

[0023] The hydrophilic membrane assembly includes a stacked waterproof and breathable membrane and a hydrophilic membrane, wherein the hydrophilic membrane is in a cavity formed by the waterproof and breathable membrane and the fin heat dissipation assembly. It can be understood that the hydrophilic membrane continuously absorbs moisture in the air. When the surface temperature of the fin heat dissipation assembly rises, by bringing the hydrophilic membrane into contact with it, the moisture can be changed from liquid to gas, taking away heat and dissipating heat through phase change. When there is no heat generation, the characteristics of the hydrophilic membrane can also be used to absorb moisture in the air, which is particularly suitable for working scenarios with intermittent heat generation.

[0024] An embodiment of the second aspect of the present application provides an energy storage device, including: a shell, in which a heat generating element is disposed; and a heat dissipation component, at least part of which is disposed in the shell.

[0025] The energy storage device provided in the present application includes a shell and a heat dissipation component partially disposed in the shell. By arranging a heating element in the shell, the characteristics of the hydrophilic membrane can be used to dissipate heat from the heating element. The heat dissipation component ensures that the heating element maintains a suitable temperature during operation through an effective heat dissipation mechanism, thereby preventing performance degradation and safety hazards caused by overheating.

[0026] It should be emphasized that for the working scenarios of the chip on the circuit board of the battery of the energy storage device or the inverter, the intermittent working characteristics of the hydrophilic film can be used to dissipate the heat of the chip during charging and discharging. When the chip is not working, the hydrophilic film can gradually absorb water vapor in the environment to meet the subsequent heat dissipation needs.

[0027] It can be understood that under the action of the hydrophilic film, water can be automatically replenished when the chip works intermittently, maintaining heat dissipation performance and reducing manual intervention.

[0028] Since the energy storage device includes any of the above-mentioned heat dissipation components, it has the beneficial effects of any of the above-mentioned heat dissipation components, which will not be described in detail here.

[0029] Among them, energy storage equipment includes but is not limited to energy storage batteries, energy storage inverters and other equipment.

[0030] In some technical solutions, optionally, a mounting opening is provided on the wall of the shell, the heat conducting part is located inside the shell, and one side of the heat conducting part is against the mounting opening, and the other side is in contact with the heating element.

[0031] In this technical solution, a shell is provided to provide protection, support and installation functions, ensure the stability of the internal heating components and heat-conducting parts, and provide a good heat dissipation environment.

[0032] By providing a mounting opening on the wall of the shell, it is convenient to install the fin heat dissipation assembly, thereby allowing air circulation or water evaporation. Specifically, the heat conduction part is located in the shell, and effectively conducts heat from the heating element to the fin heat dissipation assembly and the hydrophilic membrane assembly. The setting of the heat conduction part ensures that heat can be efficiently transferred inside the shell. At the same time, one side of the heat conduction part is against the mounting opening, providing a contact surface between the fin heat dissipation assembly or the hydrophilic membrane assembly and the external environment, so that the fin part extends out of the mounting opening, enhancing the air circulation of the fin heat dissipation assembly, and further improving the heat dissipation efficiency.

[0033] Among them, the other side of the heat conduction part is in contact with the heating element, directly absorbing heat from the heating element, and serving as a medium for heat conduction, ensuring that heat can be quickly transferred from the heating element to the heat conduction part, providing a basis for the subsequent heat dissipation process.

[0034] It can be understood that the close contact between the heat-conducting part and the heat-generating element ensures that the heat can be quickly transferred to the heat dissipation system in the housing.

[0035] In some technical solutions, optionally, at least part of the fin heat dissipation assembly is arranged outside the installation opening, and the heat conduction part is in contact with the wall of the shell where the installation opening is arranged.

[0036] By setting a part of the fin heat dissipation assembly on one side of the installation opening, specifically on the outside, the heat conducting part is attached to the outer wall of the shell, that is, attached to the outer surface of the wall of the shell where the installation opening is provided. On this basis, the fin heat dissipation assembly and the shell can be fixed by means of snaps, screws, etc., so as to ensure the stability of the relative position between the heat generating element inside the shell and the fin heat dissipation assembly, thereby improving the heat dissipation effect.

[0037] In some technical solutions, optionally, it also includes: a first matching piece, which is arranged on the same wall of the shell as the installation port; a second matching piece, which is arranged on the heat conducting part; wherein the assembly of the fin heat dissipation assembly and the shell is achieved by matching the first matching piece and the second matching piece.

[0038] In this technical solution, a first matching piece and a second matching piece are provided, and the first matching piece is provided on the same wall as the mounting opening, and the second matching piece is provided on the heat conducting part, and the position and fixation of the fin heat dissipation assembly are ensured by the cooperation between the two.

[0039] It can be understood that, through the design of these two mating parts, the fin heat dissipation assembly and the housing can be assembled quickly and accurately, reducing assembly time and complexity, improving production efficiency, and reducing the skill requirements for assemblers.

[0040] By connecting the first fitting and the second fitting, close contact between the heat conducting part and the fin heat dissipation assembly is ensured, the heat conduction efficiency is enhanced, the heat conduction path is optimized, and it is ensured that heat can be quickly transferred from the heating element to the fin heat dissipation assembly through the heat conducting part, thereby improving the heat dissipation effect.

[0041] Ensure the fixed position of the fin heat dissipation assembly in the shell to avoid loosening due to thermal expansion and contraction or vibration during operation, enhance the overall stability of the heat dissipation system, and ensure reliability and performance in long-term operation.

[0042] In some technical solutions, optionally, the first matching piece and the second matching piece are connected by magnetic attraction.

[0043] In this technical solution, the first matching piece and the second matching piece are connected by magnetic attraction, and magnetic force is used to achieve quick and convenient connection and separation. Under the action of magnetism, a certain guiding effect is played on the assembly between the heat conducting part and the fin heat dissipation component, making the assembly and disassembly of the heat conducting part and the fin heat dissipation component faster and more convenient, reducing operation time and labor intensity.

[0044] In addition, since the magnetic connection does not rely on physical locking, it avoids the wear or damage that may be caused by threaded connections, extending the service life of the components. It can be understood that the magnetic connection allows a certain degree of displacement and adjustment, which can adapt to the expansion or contraction caused by temperature changes and maintain a good connection state.

[0045] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0061] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0062] Refer to the following Figures 1 to 11 Some embodiments according to the present invention are described.

[0063] like Figure 1 and Figure 2 As shown, this embodiment provides a heat dissipation component 100, including a hydrophilic membrane component 101 and a fin heat dissipation component 102. The hydrophilic membrane component 101 and the fin heat dissipation component 102 are combined to achieve efficient, stable, and noiseless heat dissipation effects, and are suitable for equipment that requires long-term reliable operation and low maintenance costs. Specifically, the hydrophilic membrane component 101 can reduce the temperature of the heating element by absorbing moisture in the air and dissipating heat using phase change. Figure 3 As shown, the fin heat dissipation assembly 102 includes a heat conduction portion 1022 and a fin portion 1024, wherein the heat conduction portion 1022 is in direct or indirect contact with the heating element so as to receive the heat generated by the heating element, so as to achieve heat dissipation under the joint action of the fin portion and the hydrophilic membrane assembly, and is usually made of a high thermal conductivity material, such as copper or aluminum. The fin portion 1024 is connected to the heat conduction portion 1022 to expand the heat conduction area and improve the heat dissipation efficiency, and is usually a multi-piece thin metal sheet structure.

[0064] The heat conducting part 1022 will quickly conduct heat from the heating element and conduct it to the fin part 1024. Under the action of the fin part 1024, the heat dissipation surface area is increased to accelerate the heat dissipation. Combined with the hydrophilic membrane component 101, the heat dissipation efficiency is further improved.

[0065] It should be added that part or all of the hydrophilic membrane assembly can be arranged on the fin part, and of course can also be arranged at the position of the heat conduction part, and the specific position can be arranged on the outer surface or inner surface of the fin part.

[0066] Furthermore, the hydrophilic membrane assembly can be provided on a part of the outer surface or the entire outer surface of the fin portion according to requirements.

[0067] The heat conducting part 1022 is in direct or indirect contact with the heating element, and can quickly conduct the heat to the fin part 1024, and then dissipate the heat through the hydrophilic membrane assembly 101, which continuously absorbs moisture in the air. When the heat is conducted to the hydrophilic membrane assembly, the water evaporates and takes away a large amount of latent heat. Finally, the evaporated water vapor escapes into the air through the hydrophilic membrane assembly 101. When the equipment stops working, the hydrophilic membrane assembly 101 continues to absorb moisture in the air, replenishes the stored water, and prepares for the next heat dissipation cycle.

[0068] Among them, Fig.11 As shown, the hydrophilic membrane assembly 101 includes a waterproof and breathable membrane 1182 and a hydrophilic membrane 1184 which are stacked, wherein the hydrophilic membrane 1184 is in a cavity 120 formed by the waterproof and breathable membrane 1182 and the fin heat dissipation assembly 102. It can be understood that the hydrophilic membrane 1184 continuously absorbs moisture in the air. When the surface temperature of the fin heat dissipation assembly 102 rises, by bringing the hydrophilic membrane 1184 into contact with it, moisture can be changed from liquid to gas, taking away heat and dissipating heat through phase change. When there is no heat generation, the characteristics of the hydrophilic membrane 1184 can also be used to absorb moisture in the air, which is particularly suitable for working scenarios with intermittent heating.

[0069] In some embodiments, optionally, Figure 3 As shown, the fin portion 1024 includes a plurality of fins 1026 disposed at intervals, and the hydrophilic membrane assembly 101 is disposed on at least one side of the fin 1026 .

[0070] In this embodiment, the fin portion 1024 includes a plurality of fins 1026, and adjacent fins 1026 do not contact each other but have gaps therebetween, thereby providing a larger heat dissipation surface area while maintaining good air circulation, thereby enhancing heat conduction and dissipation efficiency, and ensuring that heat can be quickly transferred from the heat generating element to the surface of the fin 1026 for heat dissipation.

[0071] By fixing the hydrophilic membrane assembly 101 on at least one side of the fin 1026, the hydrophilic membrane is in direct contact with the surface of the fin 1026, thereby optimizing the heat conduction path. Heat can be quickly transferred to the hydrophilic membrane, so that the hydrophilic membrane absorbs heat and evaporates water, thereby taking away the heat. The contact area between the hydrophilic membrane and the fin 1026 is optimized, ensuring that heat can be quickly transferred to the hydrophilic membrane, achieving efficient heat dissipation and water evaporation, and further improving the overall heat dissipation performance, ensuring that the equipment maintains a low temperature while operating efficiently, and improving the reliability and service life of the equipment.

[0072] By utilizing the fins 1026 that are arranged at intervals, heat can be quickly transferred and dissipated through a larger surface area, avoiding heat accumulation, improving heat dissipation efficiency, maintaining air circulation, and avoiding heat accumulation between the fins 1026, so that the entire heat dissipation structure can exchange heat more efficiently.

[0073] In some embodiments, optionally, Figure 5 As shown, the hydrophilic membrane assembly 101 is placed on the side of the heat conductive portion 1022 away from the heat source so that it does not directly contact the heat generating element. Instead, the heat generated by the heat generating element in direct contact with the hydrophilic membrane assembly is transferred to the hydrophilic membrane assembly through the heat conductive portion 1022, thereby achieving heat dissipation and ensuring that the hydrophilic membrane assembly 101 can operate in a relatively stable temperature environment, avoiding the direct impact of high temperature on the hydrophilic membrane, thereby improving its service life and heat dissipation efficiency.

[0074] It can be understood that in this solution, in a high temperature environment, the hydrophilic membrane component 101 can maintain good performance and avoid material aging or performance degradation caused by direct contact with high temperature. The hydrophilic membrane component 101 is far away from the heating element, which reduces the impact of thermal stress on it, enhances the overall reliability of the system, and ensures that the heat dissipation system can maintain stable performance during long-term use, thereby extending the service life of the equipment.

[0075] In some embodiments, optionally, Figure 3 As shown, an insulating heat-conducting medium 116 is arranged between the heat-conducting portion 1022 and the heating element 202, and the insulating heat-conducting medium 116 covers the heating element 202, so that the heat generated by the heating element 202 can be transferred to the heat-conducting portion 1022 through the insulating heat-conducting medium 116, and then transferred to the hydrophilic membrane assembly through the fin portion 1024, thereby achieving efficient heat dissipation.

[0076] It can be understood that the projection of the heating element 202 on the insulating heat-conducting medium 116 is inside the insulating heat-conducting medium 116 , which can increase the contact area between the heating element 202 and the insulating heat-conducting medium 116 and improve the heat conduction efficiency.

[0077] like Figure 6As shown, an embodiment of the second aspect of the present application provides an energy storage device 200, including a heat dissipation component 100. By arranging a heating element 202 in a shell, the characteristics of the hydrophilic membrane can be used to dissipate heat for the heating element 202. The heat dissipation component 100 ensures that the heating element 202 maintains a suitable temperature during operation through an effective heat dissipation mechanism, thereby preventing performance degradation and safety hazards caused by overheating.

[0078] It should be emphasized that for the working scenario of the chip of the energy storage device 200, the hydrophilic membrane component 101 can be used to dissipate the heat of the chip during charging and discharging. When the chip is not charging and discharging, the hydrophilic membrane component 101 can gradually absorb water vapor in the environment to meet subsequent heat dissipation needs.

[0079] It can be understood that the hydrophilic membrane assembly 101 ensures heat dissipation of the battery and reduces maintenance costs. Since the energy storage device 200 includes any of the above heat dissipation assemblies 100, it has the beneficial effects of any of the above heat dissipation assemblies 100, which will not be described in detail.

[0080] The energy storage device 200 includes but is not limited to energy storage batteries, energy storage inverters and other devices.

[0081] In one embodiment, optionally, Figure 3 As shown, the fin heat dissipation component 102 is arranged on one side of the installation opening 1082, specifically on the outer side, and the heat conducting part 1022 is attached to the outer wall of the shell 108, that is, it is attached to the outer surface of the wall of the shell 108 on which the installation opening 1082 is provided. On this basis, the fin heat dissipation component 102 and the shell 108 can be fixed by means of snaps, screws, etc., so as to ensure the stability of the relative position between the heat generating element 202 inside the shell 108 and the fin heat dissipation component 102, thereby improving the heat dissipation effect.

[0082] In some embodiments, a housing 108 is optionally provided to provide protection, support and installation functions, ensure the stability of the internal heating element and the heat conducting part 1022, and provide a good heat dissipation environment.

[0083] By providing a mounting opening 1082 on the wall of the housing 108, the fin heat dissipation assembly 102 is conveniently installed, thereby allowing air circulation or water evaporation. Specifically, the heat conducting portion 1022 is located in the housing 108, and effectively conducts heat from the heating element to the fin heat dissipation assembly 102 and the hydrophilic membrane assembly 101. The setting of the heat conducting portion 1022 ensures that heat can be efficiently transferred inside the housing 108. At the same time, one side of the heat conducting portion 1022 abuts against the mounting opening 1082, providing a contact surface between the fin heat dissipation assembly 102 or the hydrophilic membrane assembly 101 and the external environment, so that the fin portion 1024 extends out of the mounting opening 1082, thereby enhancing the air circulation of the fin heat dissipation assembly 102 and further improving the heat dissipation efficiency.

[0084] The other side of the heat conducting portion 1022 is in contact with the heating element, directly absorbing heat from the heating element and serving as a medium for heat conduction, thereby ensuring that heat can be quickly transferred from the heating element to the heat conducting portion 1022 , providing a basis for the subsequent heat dissipation process.

[0085] It can be understood that the close contact between the heat conducting portion 1022 and the heat generating element ensures that the heat can be quickly transferred to the heat dissipation system in the housing 108 .

[0086] In some embodiments, optionally, Figure 4 As shown, a seal 110 is provided to seal the gap between the heat-conducting portion 1022 and the shell 108 to prevent leakage of heat and air, thereby ensuring that the heat of the heating element can be effectively transferred to the heat-conducting portion 1022 and then discharged to the outside through the fin portion 1024 and the hydrophilic membrane assembly 101 provided on the fin portion 1024.

[0087] Among them, the design of the seal 110 matches the shape of the heat conducting part 1022. The seal 110 effectively seals the gap between the heat conducting part 1022 and the shell 108 to prevent external moisture and cold air from entering the interior, reduce the formation of condensed water, effectively isolate the moisture from the external environment, prevent the accumulation of condensed water between the heat conducting part 1022 and the shell 108, and reduce the impact of condensed water on equipment performance and life.

[0088] In some embodiments, optionally, Figure 2 , Figure 4 As shown, a first matching piece 1142 and a second matching piece 1144 are provided, and the first matching piece 1142 is provided on the same wall as the mounting opening 1082, and the second matching piece 1144 is provided on the heat conducting portion 1022, and the position and fixation of the fin heat dissipation assembly 102 are ensured by the cooperation between the two.

[0089] It can be understood that, through the design of these two mating parts, the fin heat dissipation assembly 102 and the housing 108 can be assembled quickly and accurately, reducing assembly time and complexity, improving production efficiency, and reducing the skill requirements for assemblers.

[0090] By connecting the first fitting 1142 and the second fitting 1144, close contact between the heat conducting part 1022 and the fin heat dissipation assembly 102 is ensured, the heat conduction efficiency is enhanced, the heat conduction path is optimized, and it is ensured that heat can be quickly transferred from the heating element to the fin heat dissipation assembly 102 through the heat conducting part 1022, thereby improving the heat dissipation effect.

[0091] Ensure that the fin heat dissipation assembly 102 is fixed in the housing 108 to avoid loosening due to thermal expansion and contraction or vibration during operation, enhance the overall stability of the heat dissipation system, and ensure reliability and performance in long-term operation.

[0092] In some embodiments, optionally, Figure 4 As shown, the first matching piece 1142 and the second matching piece 1144 are magnetically connected.

[0093] In this embodiment, the first mating piece 1142 and the second mating piece 1144 are connected by magnetic attraction, and magnetic force is used to achieve quick and convenient connection and separation. Under the action of magnetism, the assembly between the heat conducting part 1022 and the fin heat dissipation component 102 is guided to a certain extent, so that the assembly and disassembly of the heat conducting part 1022 and the fin heat dissipation component 102 becomes faster and more convenient, reducing the operation time and labor intensity.

[0094] In addition, since the magnetic connection does not rely on physical locking, it avoids the wear or damage that may be caused by threaded connections, extending the service life of the components. It can be understood that the magnetic connection allows a certain degree of displacement and adjustment, which can adapt to the expansion or contraction caused by temperature changes and maintain a good connection state.

[0095] like Figure 7 and Figure 8 As shown, Figure 7 A temperature schematic diagram showing an energy storage device according to an embodiment of the present utility model charging at 0.5C for 1 hour at a temperature of 45°C; Figure 8 The schematic diagram shows the temperature of the energy storage device without heat dissipation components in the energy storage device, which is charged at 45°C for 1 hour at 0.5C. By comparison, it can be clearly seen that Figure 7 The brightness is much lower than Figure 8 The brightness is higher and the temperature is lower. In this solution, the heat dissipation effect caused by the provision of a hydrophilic membrane component is much greater than the heat dissipation effect corresponding to the solution without the provision of a hydrophilic membrane component.

[0096] like Fig. 9 and Fig.10 As shown, Fig. 9 A temperature schematic diagram showing an energy storage device according to an embodiment of the present utility model being charged at 1C for 1 hour at a temperature of 45°C; Fig.10 A temperature diagram showing an energy storage device without a heat dissipation component being charged at 1C for 1 hour at a temperature of 45°C.
