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, including: a shell, in which a heat generating element is arranged; a hydrophilic membrane component, which is arranged on the shell and adhered to the wall of the shell; wherein at least part of the hydrophilic membrane component is connected to the air outside the shell.

[0007] According to the heat dissipation component proposed by the utility model, a high-efficiency thermal management system is formed by combining a hydrophilic membrane component with a shell. The hydrophilic membrane component utilizes the phase change process of water (from liquid to gas) to absorb a large amount of heat, thereby effectively reducing the temperature of the heating element in the shell.

[0008] It should be emphasized that the hydrophilic membrane components are connected to the outside air and can continuously absorb moisture in the air to ensure the continuity and stability of the heat dissipation process. The power-free and fan-free design also reduces the wear of mechanical parts, reduces maintenance costs, and extends the service life of the product.

[0009] Specifically, a heating element is disposed inside the shell to protect the internal heating element, wherein the shell is fitted with the hydrophilic membrane component to form a closed heat dissipation environment, and the hydrophilic membrane component is connected to the outside air to allow the absorption and evaporation of moisture.

[0010] The heating element generates heat, which will cause the temperature inside the shell to rise when it is working. The heating element is in direct contact with the hydrophilic membrane component, ensuring that the heat can be effectively transferred to the hydrophilic membrane component, thereby promoting the heat dissipation efficiency of the hydrophilic membrane component.

[0011] Among them, the hydrophilic membrane component is responsible for absorbing moisture in the air and using its phase change to dissipate heat. The evaporation of moisture takes away heat and can also reduce the temperature inside the shell. The hydrophilic membrane component is attached to the wall of the shell to form an effective heat exchange interface.

[0012] The hydrophilic membrane components are tightly fitted to the shell wall by bonding or mechanical fixing to ensure that heat can be quickly conducted. At least part of the hydrophilic membrane components are connected to the outside air to form an open system, so that the moisture in the layer can be continuously absorbed and evaporated. This design makes the heat dissipation effect unrestricted.

[0013] Among them, hydrophilic membrane components usually choose materials with good hydrophilicity, which can absorb water efficiently and have good air permeability so that water can evaporate smoothly. Between the heating element and the hydrophilic membrane component, a thermal conductive material (such as thermal conductive glue) can be added to improve the heat conduction efficiency and ensure that heat can be quickly transferred to the hydrophilic membrane component.

[0014] In some technical solutions, optionally, a plurality of air holes are provided on the wall of the shell, the hydrophilic membrane assembly is in contact with the inner wall surface of the shell, and at least part of the hydrophilic membrane assembly is connected to the outside through the air holes.

[0015] In this technical solution, air holes are provided on the wall of the shell, and the hydrophilic membrane assembly can be attached to the inner wall surface of the shell, allowing outside air to enter the shell through the air holes. External moisture can more easily contact the hydrophilic membrane assembly, thereby improving its water absorption efficiency, enhancing the heat dissipation capacity of the hydrophilic membrane assembly, making the water evaporation process more efficient, and thus improving the overall heat dissipation performance.

[0016] In this solution, the hydrophilic membrane component is attached to the inner wall surface of the shell. The hydrophilic membrane component is arranged inside the shell and is connected to the outside world through air holes. The hydrophilic membrane component can continuously absorb moisture from the external environment and maintain its moist state, ensuring that when the heating element is working, heat can be dissipated through the evaporation of the hydrophilic membrane component, continuously providing a cooling effect, and when the heating element stops working, it can still replenish moisture through the outside air, thereby extending the service life and improving the self-maintenance capability of the system.

[0017] In some technical solutions, optionally, the hydrophilic membrane assembly includes: a hydrophilic membrane; a supporting heat-conducting layer, which is arranged on a side of the hydrophilic membrane away from the inner wall surface of the shell, and the supporting heat-conducting layer is in contact with the hydrophilic membrane.

[0018] In this technical solution, the supporting heat-conducting layer is located on the side of the hydrophilic membrane away from the shell, and is directly attached to the hydrophilic membrane. Under the action of the supporting heat-conducting layer, on the one hand, it can provide structural support to ensure that the hydrophilic membrane component maintains a stable shape during operation and prevents it from deforming due to thermal expansion or pressure changes. The existence of the supporting heat-conducting layer enhances the mechanical strength of the hydrophilic membrane component, ensuring that it can still work effectively in a high-temperature environment and avoid the decrease in heat dissipation efficiency due to deformation. On the other hand, the attachment of the supporting heat-conducting layer to the hydrophilic membrane component further optimizes the heat conduction interface, ensuring that heat can be quickly transferred from the heating element to the hydrophilic membrane through the supporting heat-conducting layer, thereby achieving evaporative heat dissipation.

[0019] It should be added that the supporting heat-conducting layer needs to have a certain heat-conducting property so that the heat can be transferred to the hydrophilic membrane assembly. The supporting heat-conducting layer can be provided with openings to facilitate efficient heat transfer.

[0020] In some technical solutions, optionally, it also includes: a filter screen, which is arranged corresponding to the air vents, and the filter screen is arranged on the outer wall surface of the shell.

[0021] In this technical solution, the filter screen is arranged corresponding to the air vents and is located on the outer wall of the shell. Its main function is to filter dust, dirt and other particulate matter in the external air to prevent them from entering the shell and protect the hydrophilic membrane assembly and other internal components.

[0022] By blocking impurities, the filter effectively extends the service life of the hydrophilic membrane assembly and the entire heat dissipation assembly, maintains the high efficiency of the heat dissipation system, and reduces the decrease in heat dissipation efficiency caused by dirt accumulation.

[0023] Among them, the filter directly covers the outside of the air vent, ensuring that the air entering the shell is first filtered when passing through the filter, ensuring that only clean air can enter the interior.

[0024] In some technical solutions, optionally, the hydrophilic membrane assembly is in contact with the outer wall surface of the shell.

[0025] In this technical solution, the hydrophilic membrane component is fitted to the outer wall of the shell to form an effective heat exchange interface. This fit ensures that the external air can directly contact the hydrophilic membrane component, promoting the absorption and evaporation of water.

[0026] Through this bonding, the hydrophilic membrane component can more effectively absorb moisture from the external environment and convert it into steam to take away the heat generated by the heating element. The bonding of the hydrophilic membrane component to the outer wall of the shell enhances the heat exchange capacity, making the heat dissipation process more efficient and stable, and further improving the overall performance and reliability of the heat dissipation component.

[0027] In some technical solutions, optionally, it also includes: a mesh plate, which is arranged on a side of the hydrophilic membrane assembly away from the outer wall of the shell, and the mesh plate is connected to the outer wall of the shell to form a cavity for accommodating the hydrophilic membrane assembly.

[0028] In this technical solution, when the hydrophilic membrane assembly is attached to the outer wall of the shell, a mesh plate is provided on the side of the hydrophilic membrane assembly away from the shell, and a cavity for accommodating the hydrophilic membrane assembly is formed between the mesh plate and the outer wall of the shell, so that the hydrophilic membrane assembly can work in a stable space.

[0029] The introduction of the mesh provides the necessary support and protection for the hydrophilic membrane assembly, preventing it from deforming due to thermal expansion or external pressure changes during operation. At the same time, the design of the mesh also allows air to circulate in the cavity, promoting heat dissipation.

[0030] In some technical solutions, optionally, the hydrophilic membrane assembly includes: a hydrophilic membrane; an adhesive thermal conductive layer, disposed on one side of the hydrophilic membrane; wherein the adhesive thermal conductive layer is disposed between the hydrophilic membrane and the wall of the shell, and the hydrophilic membrane is adhered to the wall of the shell through the adhesive thermal conductive layer.

[0031] In this technical solution, the adhesive heat-conducting layer is located on one side of the hydrophilic membrane assembly, and is mainly used to firmly bond the hydrophilic membrane assembly to the wall surface of the shell, ensuring a close bond between the two. The hydrophilic membrane assembly can more effectively transfer heat to the shell, reduce thermal resistance, and enhance heat dissipation efficiency. At the same time, the presence of the adhesive heat-conducting layer prevents the hydrophilic membrane assembly from being displaced or falling off during operation, thereby improving the overall stability of the assembly.

[0032] The waterproof breathable membrane is set on the other side of the hydrophilic membrane component, which is designed to protect the hydrophilic membrane component from external liquid intrusion while allowing water vapor to pass through and maintain air circulation. While keeping dry, the hydrophilic membrane component can effectively absorb and evaporate water. This not only enhances the heat dissipation performance, but also prevents possible failures caused by moisture accumulation.

[0033] The hydrophilic membrane component is bonded to the wall of the shell through the adhesive heat-conducting layer to form a tight heat exchange interface, which ensures that heat can be quickly transferred from the heating element to the hydrophilic membrane component, optimizes the heat dissipation process, and improves the overall heat dissipation efficiency of the system.

[0034] In some technical schemes, optionally, the shell includes at least a high-temperature cavity and a low-temperature cavity, the heating element is arranged in the high-temperature cavity, part of the hydrophilic membrane assembly is arranged on the wall of the shell corresponding to the high-temperature cavity, and part of the hydrophilic membrane assembly is arranged on the wall of the shell corresponding to the low-temperature cavity.

[0035] In the present scheme, the space inside the shell is divided into at least one high-temperature chamber and at least one low-temperature chamber, wherein a heating element is arranged in the high-temperature chamber. When the heating element is in operation, the hydrophilic membrane component located in the high-temperature chamber first evaporates and absorbs heat to achieve heat dissipation in the high-temperature chamber. If the heat absorption and evaporation capacity of this part of the hydrophilic membrane component is low, then part of the hydrophilic membrane component in the low-temperature chamber will be used to absorb the remaining heat of the high-temperature chamber, which will be discharged outwardly by evaporation, thereby improving the heat dissipation effect.

[0036] Of course, the hydrophilic membrane component can be set on the inner wall surface of the high-temperature chamber or the low-temperature chamber, or on the outer wall surface of the high-temperature chamber and the low-temperature chamber. However, no matter where the hydrophilic membrane component is set, the entire hydrophilic membrane component is connected internally to facilitate achieving stronger heat dissipation capabilities.

[0037] In some technical solutions, optionally, the area of ​​the part of the hydrophilic membrane assembly corresponding to the high-temperature cavity is larger than the area of ​​the part of the hydrophilic membrane assembly corresponding to the low-temperature cavity.

[0038] A larger hydrophilic membrane component is set in the high-temperature cavity, and a smaller hydrophilic membrane component in the low-temperature cavity is set to meet the heat dissipation requirements. That is, the large-area hydrophilic membrane component has a rapid heat dissipation effect on the temperature in the high-temperature cavity, and the small-area hydrophilic membrane component in the low-temperature cavity is used to improve the heat dissipation capacity of the hydrophilic membrane component to meet greater heat dissipation requirements, thereby adapting to more scenarios and improving product applicability.

[0039] An embodiment of the second aspect of the present application provides an energy storage device, including: any of the above-mentioned heat dissipation components.

[0040] The energy storage device provided in the present application includes a heat dissipation component. By arranging a heating element in the shell, the characteristics of the hydrophilic membrane component 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.

[0041] It should be emphasized that for the working scenario of the battery of the energy storage device, the hydrophilic membrane component can be used to dissipate the heat of the battery during charging and discharging. When the battery is not charging and discharging, the hydrophilic membrane component can gradually absorb water vapor in the environment to meet the subsequent heat dissipation needs.

[0042] It can be understood that under the action of the hydrophilic membrane assembly, the heat dissipation of the battery is ensured and the maintenance cost is reduced.

[0043] 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.

[0044] Among them, energy storage equipment includes but is not limited to energy storage batteries, energy storage inverters and other equipment.

[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

[0063] 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.

[0064] 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.

[0065] Refer to the following Figures 1 to 14 Some embodiments according to the present invention are described.

[0066] like Figure 1 and Figure 7 As shown, a heat dissipation component 100 proposed in this embodiment adopts a combination of a hydrophilic membrane component 101 and a shell 108 to form an efficient thermal management system. The hydrophilic membrane component 101 utilizes the phase change process of water (from liquid to gas) to absorb a large amount of heat, thereby effectively reducing the temperature of the heating element 202 in the shell 108.

[0067] It should be emphasized that the hydrophilic membrane component 101 is connected to the outside air and can continuously absorb moisture in the air to ensure the continuity and stability of the heat dissipation process. In addition, the use of a power-free and fan-free design reduces the wear of mechanical parts, reduces maintenance costs, and extends the service life of the product.

[0068] Specifically, a heating element 202 is disposed inside the shell 108 to protect the internal heating element 202, wherein the shell 108 is attached to the hydrophilic membrane assembly 101 to form a closed heat dissipation environment, and the hydrophilic membrane assembly 101 is connected to the outside air to allow the absorption and evaporation of moisture.

[0069] The heating element 202 generates heat, which causes the temperature inside the housing 108 to rise when it is working. The heating element 202 is in direct contact with the hydrophilic membrane assembly 101, ensuring that the heat can be effectively transferred to the hydrophilic membrane assembly 101, thereby promoting the heat dissipation efficiency of the hydrophilic membrane assembly 101.

[0070] The hydrophilic membrane assembly 101 absorbs moisture from the air and uses its phase change to dissipate heat. The evaporation of moisture takes away heat and can also reduce the temperature inside the shell 108. The hydrophilic membrane assembly 101 is attached to the wall of the shell 108 to form an effective heat exchange interface.

[0071] The hydrophilic membrane assembly 101 is tightly fitted to the wall of the shell 108 by bonding or mechanical fixing to ensure that heat can be quickly conducted. At least part of the hydrophilic membrane assembly 101 is connected to the external air to form an open system, so that the moisture in the layer can be continuously absorbed and evaporated. This design makes the heat dissipation effect unrestricted.

[0072] The hydrophilic membrane assembly 101 is usually made of a material with good hydrophilicity, which can efficiently absorb water and has good air permeability so that the water can evaporate smoothly. A heat-conducting material (such as a heat-conducting glue) can be added between the heating element 202 and the hydrophilic membrane assembly 101 to improve the heat conduction efficiency and ensure that the heat can be quickly transferred to the hydrophilic membrane assembly 101.

[0073] like Figure 3 As shown, air holes 110 are provided on the wall of the shell 108, and the hydrophilic membrane assembly 101 can be attached to the inner wall surface of the shell 108, allowing outside air to enter the shell 108 through the air holes 110, so that moisture from the outside can more easily contact the hydrophilic membrane assembly 101, thereby improving its water absorption efficiency, enhancing the heat dissipation capacity of the hydrophilic membrane assembly 101, making the evaporation process of water more efficient, and thus improving the overall heat dissipation performance.

[0074] In this solution, the hydrophilic membrane component 101 is attached to the inner wall surface of the shell 108. The hydrophilic membrane component 101 is arranged in the shell 108 and is connected to the outside world through the air vent 110. The hydrophilic membrane component 101 can continuously absorb moisture from the external environment and maintain its moist state, ensuring that when the heating element 202 is working, heat can be dissipated through the evaporation of the hydrophilic membrane component 101, continuously providing a cooling effect, and when the heating element 202 stops working, it can still replenish moisture through the outside air, thereby extending the service life and improving the self-maintenance capability of the system.

[0075] It can be understood that this solution has low requirements for air circulation and is an open heat dissipation solution. Specifically, the heat dissipation principle of the hydrophilic membrane component is to quickly absorb water in the air through the temperature difference on both sides of the heat dissipation material and condense into the capillary structure. Under the action of the capillary structure, the water is concentrated to the heat source for active circulation heat dissipation, thereby avoiding the problem of low heat dissipation efficiency caused by poor air circulation in a small space.

[0076] It should be added that the heat dissipation area of ​​the product is generally located against the wall and needs to be disassembled and moved to the maintenance workbench for maintenance, which has low timeliness. This solution does not require power access, and the product life can reach 12 years without maintenance. In terms of reliability, compared with traditional forced air cooling solutions, it has lower environmental requirements and does not require a large amount of air to flow through the heating area; forced air cooling requires the use of a fan, and the higher the fan speed, the greater the noise, which may cause trouble for some users who are sensitive to noise. At the same time, there is no noise interference. This solution can be installed with a thin film structure, and no noise pollution is generated.

[0077] In a specific embodiment, Figure 6 As shown, a supporting heat-conducting layer 112 is provided, and the supporting heat-conducting layer 112 is located on the side of the hydrophilic membrane 102 away from the housing 108, and is directly attached to the hydrophilic membrane 102. Under the action of the supporting heat-conducting layer 112, on the one hand, it can provide structural support to ensure that the hydrophilic membrane assembly 101 maintains a stable shape during operation and prevents it from deforming due to thermal expansion or pressure changes. The existence of the supporting heat-conducting layer 112 enhances the mechanical strength of the hydrophilic membrane assembly 101, ensuring that it can still work effectively in a high-temperature environment and avoiding a decrease in heat dissipation efficiency due to deformation. On the other hand, the attachment of the supporting heat-conducting layer 112 to the hydrophilic membrane assembly 101 further optimizes the heat conduction interface, ensuring that heat can be quickly transferred from the heating element 202 to the hydrophilic membrane 102 through the supporting heat-conducting layer 112, thereby achieving evaporative heat dissipation.

[0078] Among them, the heat of the heating element 202 is transferred to the hydrophilic membrane 102 through the supporting heat-conducting layer 112 along the direction of the arrow in the left part of the figure, and is dissipated to the outside after forming water vapor through heat absorption and evaporation. When no heat dissipation is performed, the moisture in the air will gradually be adsorbed and stored by the hydrophilic membrane 102 to facilitate subsequent evaporation and heat dissipation.

[0079] In some embodiments, optionally, Figure 5 As shown, the filter 114 is arranged corresponding to the air vent 110 and is located on the outer wall of the housing 108. Its main function is to filter dust, dirt and other particulate matter in the external air to prevent it from entering the interior of the housing 108 and protect the hydrophilic membrane assembly 101 and other internal components.

[0080] By blocking impurities, the filter 114 effectively prolongs the service life of the hydrophilic membrane assembly 101 and the entire heat dissipation assembly 100, maintains the high efficiency of the heat dissipation system, and reduces the decrease in heat dissipation efficiency caused by dirt accumulation.

[0081] The filter 114 directly covers the outside of the air vent 110 to ensure that the air entering the housing 108 is first filtered when passing through the filter 114, thereby ensuring that only clean air can enter the interior.

[0082] In a specific embodiment, optionally, Figure 4 As shown, when the hydrophilic membrane assembly 101 is attached to the outer wall of the shell, a mesh plate 122 is provided on the side of the hydrophilic membrane assembly 101 away from the shell 108. A cavity 124 for accommodating the hydrophilic membrane assembly 101 is formed between the mesh plate 122 and the outer wall of the shell, so that the hydrophilic membrane assembly 101 can work in a stable space.

[0083] The introduction of the mesh plate 122 provides necessary support and protection for the hydrophilic membrane assembly 101, preventing it from deforming due to thermal expansion or external pressure changes during operation. At the same time, the design of the mesh plate 122 also allows air to circulate in the cavity 124, promoting the heat dissipation effect.

[0084] In another embodiment, Figure 8 As shown, the hydrophilic membrane assembly 101 is arranged on the inner side of the shell, and a mesh plate 122 can also be arranged on the outer side of the shell. The openings on the mesh plate 122 provide an effective path for the hydrophilic membrane assembly to communicate with the outside air.

[0085] In a specific embodiment, optionally, Figure 2 As shown, the adhesive heat-conducting layer 104 is located on one side of the hydrophilic membrane assembly 101, and is mainly used to firmly bond the hydrophilic membrane assembly 101 to the wall surface of the housing 108 to ensure a close connection between the two. The hydrophilic membrane assembly 101 can more effectively absorb the heat transferred through the adhesive heat-conducting layer 104, thereby achieving heat dissipation. At the same time, the presence of the adhesive heat-conducting layer 104 prevents the hydrophilic membrane assembly 101 from being displaced or falling off during operation, thereby improving the overall stability of the assembly.

[0086] The hydrophilic membrane assembly 101 is bonded to the wall of the shell 108 by bonding the heat conductive layer 104 to form a tight heat exchange interface, ensuring that heat can be quickly transferred from the heating element 202 to the hydrophilic membrane assembly 101, optimizing the heat dissipation process and improving the overall heat dissipation efficiency of the system.

[0087] like Figure 2As shown, the waterproof breathable membrane 106 is arranged on the other side of the hydrophilic membrane assembly 101, which is intended to protect the hydrophilic membrane assembly 101 from external liquid intrusion while allowing water vapor to pass through to maintain air circulation. While keeping dry, the hydrophilic membrane assembly 101 can effectively absorb and evaporate water. This not only enhances the heat dissipation performance, but also prevents possible failures caused by water accumulation.

[0088] In one embodiment, optionally, Fig.14 As shown, the space inside the shell is divided into at least one high-temperature chamber 1082 and at least one low-temperature chamber 1084, wherein a heating element 202 is arranged in the high-temperature chamber 1082. When the heating element 202 is in operation, the hydrophilic membrane component 101 located in the high-temperature chamber 1082 first evaporates and absorbs heat to achieve heat dissipation in the high-temperature chamber 1082. If the heat absorption and evaporation capacity of this part of the hydrophilic membrane component 101 is low, the part of the hydrophilic membrane component 101 in the low-temperature chamber 1084 can be used to absorb the remaining heat of the high-temperature chamber 1082, which is then discharged outwardly by evaporation, thereby improving the heat dissipation effect.

[0089] Of course, the hydrophilic membrane assembly 101 can be set on the inner wall surface of the high-temperature cavity 1082 or the low-temperature cavity 1084, or on the outer wall surface of the high-temperature cavity 1082 and the low-temperature cavity 1084. However, no matter where the hydrophilic membrane assembly 101 is set, the entire hydrophilic membrane assembly 101 is connected internally to facilitate achieving stronger heat dissipation capabilities.

[0090] Furthermore, a larger hydrophilic membrane component 101 is arranged in the high-temperature cavity 1082, and a smaller hydrophilic membrane component 101 in the low-temperature cavity 1084 is arranged to meet the heat dissipation requirements. That is, the large-area hydrophilic membrane component 101 has the effect of quickly dissipating the temperature in the high-temperature cavity 1082, and the small-area hydrophilic membrane component 101 in the low-temperature cavity 1084 is used to improve the heat dissipation capacity of the hydrophilic membrane component 101 to meet a larger heat dissipation requirement, thereby adapting to a wider variety of scenarios and improving product applicability.

[0091] like Fig.13 As shown, another embodiment of the present application provides an energy storage device 200, including a heat dissipation component 100. By arranging a heating element in the shell, the characteristics of the hydrophilic membrane component 101 can be used to dissipate heat for the heating element. The heat dissipation component 100 ensures that the battery maintains a suitable temperature during operation through an effective heat dissipation mechanism, thereby preventing performance degradation and safety hazards caused by overheating.

[0092] It should be emphasized that for the working scenario of the battery of the energy storage device 200, the hydrophilic membrane component 101 can be used to dissipate the heat of the battery during charging and discharging. When the battery is not charging and discharging, the hydrophilic membrane component 101 can gradually absorb water vapor in the environment to meet subsequent heat dissipation needs.

[0093] It can be understood that, under the action of the hydrophilic membrane assembly 101, the heat dissipation of the battery is ensured and the maintenance cost is reduced.

[0094] Since the energy storage device 200 includes any of the above-mentioned heat dissipation components 100 , it has the beneficial effects of any of the above-mentioned heat dissipation components 100 , which will not be described in detail here.

[0095] Among them, energy storage equipment includes but is not limited to energy storage batteries, energy storage inverters and other equipment.

[0096] In a specific embodiment, Fig.13 As shown, the heating element 202 can be a battery, and the hydrophilic membrane component 101 is fitted with the outer wall of the shell 108 to form an effective heat exchange interface. This fit ensures that the external air can directly contact the hydrophilic membrane component 101, promoting the absorption and evaporation of water.

[0097] Through this bonding, the hydrophilic membrane assembly 101 can more effectively absorb moisture from the external environment and convert it into steam to take away the heat generated by the heating element 202. The bonding of the hydrophilic membrane assembly 101 and the outer wall of the shell 108 enhances the heat exchange capacity, making the heat dissipation process more efficient and stable, and further improving the overall performance and reliability of the heat dissipation assembly 100.

[0098] like Fig. 9 and Fig.10 As shown, Fig. 9 A temperature schematic diagram showing an energy storage device operating under a first condition according to an embodiment of the utility model is shown; Fig.10 The temperature diagram of the energy storage device without heat dissipation components in the energy storage device under the same first condition is shown. By comparison, it can be clearly seen that Fig. 9 The temperature of the highest point in the middle part of the left structure is significantly lower than Fig.10 The temperature at the highest point in the temperature is clearly visible from the color Fig. 9 The color is darker. The heat dissipation effect of this solution due to the provision of a hydrophilic membrane component is much greater than the heat dissipation effect without the provision of a hydrophilic membrane component.

[0099] like Fig.11 and Fig.12 As shown, Fig.11 A temperature schematic diagram showing an energy storage device operating under a second condition according to an embodiment of the utility model is shown; Fig.12 A temperature diagram is shown when the energy storage device is operated under the same second condition without a heat dissipation component. Fig.11 The temperature of the highest point in the middle part of the left structure is significantly lower than Fig.12 The temperature at the highest point in the temperature is clearly visible from the color Fig.11The color is darker, and it can also be clearly seen that the heat dissipation effect of the hydrophilic membrane component in this solution is better.

[0100] According to the heat dissipation component and energy storage device provided by the utility model, a high-efficiency thermal management system is formed by combining a hydrophilic membrane component with a shell.
