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 heating element. The heat dissipation component includes: a hydrophilic membrane component; a heat spreader, which is arranged on one side of the hydrophilic membrane component, and the side of the heat spreader away from the hydrophilic membrane component is in contact with the heating element.

[0007] According to the heat dissipation component proposed by the utility model, including a hydrophilic membrane component and a heat spreader, the heat generated by the heating element is evenly dispersed to the entire board surface under the action of the heat spreader to avoid local overheating. On this basis, the hydrophilic membrane component disperses the heat to the whole through contact with the heat spreader, so that the entire hydrophilic membrane component dissipates heat together, thereby improving the overall heat dissipation efficiency.

[0008] It can be understood that a heat spreader is set between the hydrophilic membrane assembly and the heating element, and the hydrophilic membrane assembly is fitted with the heat spreader, and the larger surface area of ​​the heat spreader is used to promote uniform distribution of heat. Among them, the setting of the heat spreader can evenly distribute the heat generated by the heating element to the hydrophilic membrane assembly, reduce the risk of local overheating, and ensure consistent heat dissipation efficiency in all areas. Of course, the close fit between the heat spreader, the heating element, and the hydrophilic membrane assembly ensures efficient heat transfer between the three and improves the overall heat dissipation performance.

[0009] Of course, the provision of the vapor chamber increases the structural stability of the overall heat dissipation assembly, reduces deformation or stress concentration caused by temperature changes, and extends the service life of the equipment.

[0010] The bottom layer of the hydrophilic membrane assembly is tightly fitted with the vapor chamber to ensure efficient heat conduction. The heating element is located on the other side of the vapor chamber, and the vapor chamber is in close contact with the heating element through its surface.

[0011] The design of the hydrophilic membrane assembly allows moisture to be continuously absorbed when external air flows, while not being overly affected by the external environment.

[0012] It can be understood that by combining the hydrophilic membrane component with the heat sink, the heat dissipation component can efficiently dissipate heat from the heat-generating components under a variety of environmental conditions, has the characteristics of self-maintenance and noiselessness, greatly improves the heat dissipation efficiency and product life, while reducing maintenance costs and noise pollution, and is suitable for various application scenarios with high heat dissipation requirements.

[0013] In some technical schemes, optionally, the hydrophilic membrane assembly includes: a waterproof and breathable membrane, which is arranged on one side of the hydrophilic membrane, part of the waterproof and breathable membrane is in contact with the heat spreader, and a cavity is formed between part of the waterproof and breathable membrane and the heat spreader; and a hydrophilic membrane, which is arranged in the cavity.

[0014] In this technical solution, the hydrophilic membrane assembly includes a stacked hydrophilic membrane and a waterproof and breathable layer, wherein the hydrophilic membrane is in a cavity formed by the waterproof and breathable membrane and the heat spreader. It can be understood that the hydrophilic membrane continuously absorbs moisture from the air. When the surface temperature of the heat spreader rises, the hydrophilic membrane is brought into contact with it, so that the moisture can be changed from liquid to gas, taking away the heat and dissipating the heat through phase change. When there is no heat, the characteristics of the hydrophilic membrane can also be used to absorb moisture in the air. This is particularly suitable for working scenarios with intermittent heat generation.

[0015] By placing the hydrophilic membrane in the cavity formed between the heat spreader and the waterproof breathable membrane, the cavity structure ensures that the hydrophilic membrane has enough space for phase change heat dissipation during water absorption and evaporation, and the heat dissipation effect is not affected by compression.

[0016] In some technical solutions, optionally, the hydrophilic membrane assembly includes: an adhesive heat-conducting layer, which is arranged between the hydrophilic membrane and the heat spreader, part of the waterproof and breathable membrane is connected to the adhesive heat-conducting layer, and the cavity is formed between part of the waterproof and breathable membrane and the adhesive heat-conducting layer.

[0017] By setting an adhesive heat-conducting layer and setting it on one side of the hydrophilic film, in direct contact with the heat spreader, the adhesive heat-conducting layer can be silica gel or other heat-conducting materials, effectively transferring the heat from the heat source to the hydrophilic film to evaporate the water. The waterproof breathable membrane is set on one side of the hydrophilic film, part of which is connected to the adhesive heat-conducting layer, and part of which forms a cavity between the adhesive heat-conducting layer. Because it has waterproof and breathable properties, it can prevent the entry of external liquid water, keep the interior dry, and allow the gaseous water formed when the water evaporates to pass through, maintaining a good heat dissipation effect.

[0018] It should be added that the hydrophilic film is located above the adhesive thermal conductive layer and is in close contact with the adhesive thermal conductive layer. The adhesive thermal conductive layer conducts heat to the hydrophilic film, causing the water in the hydrophilic film to evaporate and achieve heat dissipation. Between the adhesive thermal conductive layer and the waterproof breathable film, part is directly connected, and a cavity is formed between parts. The waterproof breathable film covers one side of the adhesive thermal conductive layer, part is fixed to the adhesive thermal conductive layer, and part is suspended to form a cavity.

[0019] Generally, the heat spreader is made of metal, and an adhesive heat conductive layer can be set between the hydrophilic film and the heat spreader. In this case, the adhesive heat conductive layer is usually made of an adhesive material with good thermal conductivity, which can ensure the efficiency of heat conduction while maintaining a certain degree of adhesion, so that the hydrophilic film is firmly adhered to the heat spreader to ensure that it will not be displaced or fall off during operation. It can be understood that although the main function of the adhesive heat conductive layer is bonding, it also needs to have certain thermal conductivity properties to promote heat dissipation to the outside and enhance the heat dissipation effect.

[0020] In some technical solutions, optionally, a receiving groove adapted to the shape of the hydrophilic membrane assembly is provided on the heat spreader, and the hydrophilic membrane assembly is arranged in the receiving groove.

[0021] In this technical solution, a receiving groove that matches the shape of the hydrophilic membrane assembly is provided on the vapor chamber, and the hydrophilic membrane assembly is embedded in the receiving groove. The design of the receiving groove provides a special space so that the hydrophilic membrane assembly can be firmly fixed on the vapor chamber, reducing displacement or falling off caused by vibration or temperature changes. In addition, since the shape of the receiving groove matches the hydrophilic membrane assembly, a good contact area is ensured between the two, thereby improving the heat conduction efficiency and ensuring that heat can be effectively transferred from the vapor chamber to the hydrophilic membrane assembly.

[0022] Of course, since the receiving groove is provided, the installation of the hydrophilic membrane assembly is simpler and more accurate, and the user can also conveniently disassemble and reinstall it during maintenance or replacement, thereby reducing the difficulty of operation.

[0023] Furthermore, the receiving groove is located on the surface of the heat spreader, forming a special groove structure, so that the heat spreader can effectively support the hydrophilic membrane assembly, while providing a stable working environment for it and enhancing the overall heat dissipation performance.

[0024] During assembly, the receiving tank can be used as the assembly object of the hydrophilic membrane component. After the installation is completed, the integrated heat spreader and the hydrophilic membrane component are assembled into the shell together, which reduces the difficulty of installation and improves the installation efficiency.

[0025] In some technical solutions, optionally, the hydrophilic membrane assembly fits the wall of the containing tank; or there is a gap between the hydrophilic membrane assembly and the wall of the containing tank.

[0026] In this technical solution, the hydrophilic membrane assembly fits the wall of the receiving tank. The close-fitting design maximizes the thermal contact area and improves the heat conduction efficiency, so that the heat from the heat spreader can be transferred to the hydrophilic membrane assembly more quickly. Of course, the close-fitting design can prevent dust or other contaminants from entering the receiving tank and affecting the heat dissipation performance.

[0027] Alternatively, by limiting the gap between the hydrophilic membrane assembly and the wall of the receiving tank, the gap design can allow the hydrophilic membrane assembly and the heat sink to have a certain amount of movement space during thermal expansion, thereby preventing the assembly from being damaged by mechanical stress caused by thermal expansion.

[0028] In addition, the air in the gap can act as an additional thermal insulation layer, reducing the direct transfer of heat to the environment and instead concentrating heat dissipation on the hydrophilic membrane assembly.

[0029] It should be added that the design with gaps makes the installation and removal of the hydrophilic membrane components easier, without the need for precise alignment and fixation, which facilitates maintenance and replacement.

[0030] In some technical solutions, optionally, the hydrophilic membrane assembly protrudes out of the receiving groove; or the thickness of the hydrophilic membrane assembly is the same as the height of the groove wall of the receiving groove.

[0031] In this technical solution, the hydrophilic membrane component partially protrudes from the groove wall in the receiving groove, and the protruding part can increase the contact area between the hydrophilic membrane component and the heating element, further improving the heat conduction efficiency, so that more heat can be directly transferred to the hydrophilic membrane. It can be understood that the protruding design increases the surface area of ​​the hydrophilic membrane component, which is conducive to the evaporation of water and the dissipation of heat, and enhances the heat dissipation effect.

[0032] Alternatively, by limiting the thickness of the hydrophilic membrane assembly to be consistent with the height of the groove wall of the receiving groove, the design of equal thickness ensures that the hydrophilic membrane assembly is flush with the surface of the heat sink, avoiding local poor contact caused by height difference and ensuring uniform heat conduction.

[0033] In some technical solutions, optionally, it also includes: an insulating thermally conductive sheet, which is arranged on a side of the heat spreader away from the hydrophilic membrane assembly, and the insulating thermally conductive sheet is used to fit the heating element.

[0034] In this technical solution, the insulating thermally conductive sheet is arranged on the side of the heat spreader away from the hydrophilic membrane assembly and is directly attached to the heating element. The insulating thermally conductive sheet can effectively guide the heat generated by the heating element to the heat spreader, ensuring that the heat is quickly transferred to the heat spreader and then dissipated through the hydrophilic membrane assembly.

[0035] In addition, as an insulating material, the insulating thermal conductive sheet can prevent the electrical signal or current of the heating element from leaking into the heat spreader or hydrophilic membrane assembly, thereby protecting the stability and safety of the entire heat dissipation system.

[0036] Among them, the insulating thermally conductive sheet is in contact with the surface of the heat spreader and fits with the heat generating component. The insulating thermally conductive sheet is placed between the heat spreader and the heat generating component to form a stable heat conduction path, ensuring that heat can be efficiently transferred from the heat generating component to the heat spreader and then to the hydrophilic membrane assembly.

[0037] In some technical solutions, optionally, the side of the heat spreader facing the hydrophilic membrane assembly is flat.

[0038] In this technical solution, the side of the heat spreader facing the hydrophilic membrane assembly is flat. The flat design ensures that the contact surface between the heat spreader and the hydrophilic membrane assembly is completely flat, maximizing the thermal contact area, reducing contact thermal resistance, and thus improving heat conduction efficiency.

[0039] Of course, the flat design makes it easier for the hydrophilic membrane assembly to dock with the heat sink during assembly, ensuring accurate positioning and simplifying the installation steps.

[0040] In addition, the planar contact enhances the heat conduction capacity from the heat spreader to the hydrophilic membrane assembly, so that the heat generated by the heating element can be quickly and effectively transferred to the hydrophilic membrane for heat dissipation. By ensuring good contact between the plane of the heat spreader and the hydrophilic membrane assembly, local overheating due to poor contact is avoided, thereby improving the reliability and efficiency of the overall heat dissipation system.

[0041] In some technical solutions, optionally, it also includes: a shell, a mounting opening is provided on the wall of the shell; a sealing member is provided on a side of the heat spreader facing the mounting opening, and the shape of the sealing member is adapted to the shape of the mounting opening.

[0042] In this technical solution, a mounting opening is opened on the shell, and the heat spreader is set at the mounting opening through a seal. A seal is set between the wall surfaces of the heat spreader shell, and the seal is limited to adapt to the shape of the mounting opening to seal the gap between the mounting opening and the heat spreader. When heat is dissipated, the possibility of generating condensed water can be effectively reduced, thereby improving the safety of use of equipment using the heat dissipation component.

[0043] It should be added that the hydrophilic membrane assembly is tightly attached to the upper surface of the vapor chamber and can be fixed by thermal conductive materials or adhesives. This direct connection ensures that heat can be quickly transferred to the hydrophilic membrane assembly through the vapor chamber to optimize the heat dissipation effect. The seal surrounds the edge of the vapor chamber, and the specific shape is adapted to the shape of the mounting port, so that the gap between the mounting port and the vapor chamber is effectively sealed to prevent the leakage of moisture and gas and improve the heat dissipation efficiency.

[0044] An embodiment of the second aspect of the present application provides an energy storage device, including: a heat generating element; and any one of the above-mentioned heat dissipation components, wherein the heat dissipation component is used to dissipate heat from the heat generating element.

[0045] 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 battery maintains a suitable temperature during operation through an effective heat dissipation mechanism, thereby preventing performance degradation and safety hazards caused by overheating.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] Among them, the energy storage device includes but is not limited to energy storage batteries, energy storage inverters and other devices. Additional aspects and advantages of the utility model will become apparent in the following description or be understood through the practice of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] 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.

[0065] 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.

[0066] Refer to the following Figures 1 to 11 Some embodiments according to the present invention are described.

[0067] like Figure 1As shown, this embodiment provides a heat dissipation component 100, including a hydrophilic membrane component 101 and a heat spreader 108. The heat spreader 108 is usually made of metal materials with good thermal conductivity (such as aluminum or copper). The specific size of the heat spreader 108 is generally designed according to the power and heat dissipation requirements of the heating element 202. It is usually thinner and has a larger area to increase the contact surface. Under the action of the heat spreader 108, the heat generated by the heating element 202 is evenly dispersed to the entire board surface to avoid local overheating. On this basis, the hydrophilic membrane component 101 disperses the heat to the whole through contact with the heat spreader 108, so that the entire hydrophilic membrane component 101 dissipates heat together, thereby improving the overall heat dissipation efficiency.

[0068] It is understandable that Figure 5 As shown, a heat spreader 108 is arranged between the hydrophilic membrane assembly 101 and the heating element 202, and the hydrophilic membrane assembly 101 is fitted with the heat spreader 108, and the larger surface area of ​​the heat spreader 108 is used to promote uniform distribution of heat. Among them, the setting of the heat spreader 108 can evenly distribute the heat generated by the heating element 202 to the hydrophilic membrane assembly 101, reduce the risk of local overheating, and ensure that the heat dissipation efficiency of all areas is consistent. Of course, the close fit between the heat spreader 108, the heating element 202 and the hydrophilic membrane assembly 101 ensures efficient transfer of heat between the three, and improves the overall heat dissipation performance.

[0069] Of course, since the heat spreader 108 is provided, the structural stability of the overall heat dissipation assembly 100 is increased, the deformation or stress concentration caused by temperature changes is reduced, and the service life of the equipment is extended.

[0070] The bottom layer of the hydrophilic membrane assembly 101 is closely attached to the vapor chamber 108 to ensure efficient heat conduction. The heating element 202 is located on the other side of the vapor chamber 108, and the vapor chamber 108 is in close contact with the heating element 202 through its surface.

[0071] The design of the hydrophilic membrane assembly 101 allows moisture to be continuously absorbed when external air flows, while not being excessively affected by the external environment.

[0072] It can be understood that by combining the hydrophilic membrane assembly 101 with the heat spreader 108, the heat dissipation assembly 100 can efficiently dissipate heat from the heating element 202 under a variety of environmental conditions, has the characteristics of self-maintenance and noiselessness, greatly improves the heat dissipation efficiency and product life, while reducing maintenance costs and noise pollution, and is suitable for various application scenarios with high heat dissipation requirements.

[0073] In some embodiments, optionally, Figure 2As shown, the hydrophilic membrane assembly 101 includes a hydrophilic membrane 102 and a waterproof breathable membrane 106 which are stacked, wherein the hydrophilic membrane 102 is in a cavity 118 formed by the waterproof breathable membrane 106 and the heat spreader 108. It can be understood that the hydrophilic membrane 102 continuously absorbs moisture from the air. When the surface temperature of the heat spreader 108 rises, the hydrophilic membrane 102 is brought into contact with it, so that the moisture can be changed from liquid to gas, taking away the heat and dissipating the heat through phase change. When there is no heat generation, the characteristics of the hydrophilic membrane 102 can also be used to absorb moisture in the air, which is particularly suitable for working scenarios with intermittent heating.

[0074] By placing the hydrophilic membrane 102 in the cavity 118 formed between the heat spreader 108 and the waterproof breathable membrane 106, the cavity structure ensures that the hydrophilic membrane 102 has enough space for phase change heat dissipation during water absorption and evaporation, and the heat dissipation effect is not affected by pressure.

[0075] like Figure 3 As shown, an adhesive heat-conducting layer 104 can also be provided on one side of the hydrophilic film 102, mainly used to firmly bond the hydrophilic film 102 to the heat spreader 108, ensuring a close connection between the two, and the hydrophilic film assembly 101 can better transfer the heat of the heat spreader to the hydrophilic film, thereby enhancing the heat dissipation efficiency. At the same time, the presence of the adhesive heat-conducting layer 104 prevents the hydrophilic film assembly 101 from being displaced or falling off during operation, thereby improving the overall stability of the assembly.

[0076] The hydrophilic film 102 is bonded to the heat spreader 108 through the adhesive 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 film 102, optimizing the heat dissipation process and improving the overall heat dissipation efficiency of the system.

[0077] The adhesive heat-conducting layer 104 can be silica gel or other heat-conducting materials, which can effectively transfer the heat of the heat source to the hydrophilic film 102 to evaporate the water. The waterproof breathable film 106 is arranged on one side of the hydrophilic film 102, part of which is connected to the adhesive heat-conducting layer 104, and part of which forms a cavity between the adhesive heat-conducting layer 104. Since it has waterproof and breathable properties, it can prevent the entry of external liquid water, keep the interior dry, and allow the gaseous water formed when the water evaporates to pass through, so as to maintain a good heat dissipation effect.

[0078] It should be added that the hydrophilic film 102 is located above the adhesive heat-conducting layer 104 and is in close contact with the adhesive heat-conducting layer 104. The adhesive heat-conducting layer 104 conducts heat to the hydrophilic film 102, so that the water in the hydrophilic film 102 evaporates due to heat, thereby achieving heat dissipation. The adhesive heat-conducting layer 104 and the waterproof breathable film 106 are partially directly connected, and a cavity is formed between the parts.

[0079] Generally, the heat spreader 108 is made of metal, and an adhesive heat conductive layer 104 can be set between the hydrophilic film 102 and the heat spreader 108. In this case, the adhesive heat conductive layer 104 is usually made of an adhesive material with good thermal conductivity, which can ensure the efficiency of heat conduction while maintaining a certain degree of adhesion, so that the hydrophilic film 102 is firmly adhered to the heat spreader 108 to ensure that it will not be displaced or fall off during operation. It can be understood that although the main function of the adhesive heat conductive layer 104 is bonding, it also needs to have certain thermal conductivity properties to promote heat dissipation to the outside and enhance the heat dissipation effect.

[0080] In some embodiments, optionally, Figure 6 As shown, the heat spreader 108 is provided with a receiving groove 1082 that matches the shape of the hydrophilic membrane assembly 101, and the hydrophilic membrane assembly 101 is arranged in the receiving groove 1082. The heat spreader 108 is provided with a receiving groove 1082 that matches the shape of the hydrophilic membrane assembly 101, and the hydrophilic membrane assembly 101 is embedded in the receiving groove 1082. The design of the receiving groove 1082 provides a special space so that the hydrophilic membrane assembly 101 can be firmly fixed on the heat spreader 108, reducing displacement or falling off caused by vibration or temperature changes. In addition, since the shape of the receiving groove 1082 is adapted to the hydrophilic membrane assembly 101, a good contact area is ensured between the two, thereby improving the heat conduction efficiency and ensuring that heat can be effectively transferred from the heat spreader 108 to the hydrophilic membrane assembly 101.

[0081] Of course, since the receiving groove 1082 is provided, the installation of the hydrophilic membrane assembly 101 is simpler and more accurate, and the user can also conveniently disassemble and reinstall it during maintenance or replacement, thereby reducing the difficulty of operation.

[0082] Furthermore, the receiving groove 1082 is located on the surface of the heat spreader 108, forming a special groove structure, so that the heat spreader 108 can effectively support the hydrophilic membrane assembly 101, while providing a stable working environment for it and enhancing the overall heat dissipation performance.

[0083] During assembly, the receiving groove 1082 can be used as an assembly object for the hydrophilic membrane assembly 101. After the installation is completed, the integrated heat spreader 108 and the hydrophilic membrane assembly 101 are assembled into the shell together to reduce the difficulty of installation and improve the installation efficiency.

[0084] In some embodiments, optionally, Figure 7 As shown, the hydrophilic membrane assembly 101 fits with the groove wall of the receiving groove 1082. The hydrophilic membrane assembly 101 fits with the groove wall of the receiving groove 1082, and the close fit design maximizes the thermal contact area and improves the heat conduction efficiency, so that the heat of the heat plate 108 can be transferred to the hydrophilic membrane assembly 101 more quickly. Of course, the close fit design can prevent dust or other contaminants from entering the receiving groove 1082 and affecting the heat dissipation performance.

[0085] Or, if Figure 6 As shown, by limiting the gap between the hydrophilic membrane assembly 101 and the wall of the receiving groove 1082, the gap design can allow the hydrophilic membrane assembly 101 to have a certain amount of movement space during thermal expansion, thereby preventing the assembly from being damaged by mechanical stress caused by thermal expansion.

[0086] It should be added that the design with the gap makes the installation and removal of the hydrophilic membrane assembly 101 easier, and does not require precise alignment and fixation, which is helpful for maintenance and replacement.

[0087] In some embodiments, optionally, the hydrophilic membrane assembly 101 protrudes out of the receiving groove 1082 ; or the thickness of the hydrophilic membrane assembly 101 is the same as the height of the groove wall of the receiving groove 1082 .

[0088] In this embodiment, the hydrophilic membrane assembly 101 partially protrudes from the groove wall in the receiving groove 1082, and the protruding portion can increase the contact area between the hydrophilic membrane assembly 101 and the heating element 202, further improving the heat conduction efficiency, so that more heat can be directly transferred to the hydrophilic membrane 102. It can be understood that the protruding design increases the surface area of ​​the hydrophilic membrane assembly 101, which is conducive to the evaporation of water and the loss of heat, and enhances the heat dissipation effect.

[0089] Alternatively, by limiting the thickness of the hydrophilic membrane assembly 101 to be consistent with the height of the groove wall of the receiving groove 1082, the design of the same thickness ensures that the hydrophilic membrane assembly 101 is flush with the surface of the heat spreader 108, avoiding local poor contact caused by height difference and ensuring uniform heat conduction.

[0090] In some embodiments, optionally, Figure 4 As shown, it also includes: an insulating heat-conducting sheet 110, which is arranged on a side of the heat spreader 108 away from the hydrophilic membrane assembly 101, and the insulating heat-conducting sheet 110 is used to fit with the heating element 202.

[0091] In this embodiment, the insulating thermally conductive sheet 110 is disposed on the side of the heat spreader 108 away from the hydrophilic membrane assembly 101, and is directly attached to the heating element 202. The insulating thermally conductive sheet 110 can effectively guide the heat generated by the heating element 202 to the heat spreader 108, ensuring that the heat is quickly transferred to the heat spreader 108, and then dissipated through the hydrophilic membrane assembly 101.

[0092] In addition, as an insulating material, the insulating thermally conductive sheet 110 can prevent the electrical signal or current of the heating element 202 from leaking into the heat spreader 108 or the hydrophilic membrane assembly 101, thereby protecting the stability and safety of the entire heat dissipation system.

[0093] Among them, the insulating thermally conductive sheet 110 contacts the surface of the heat spreader 108 and fits with the heating element 202. The insulating thermally conductive sheet 110 is placed between the heat spreader 108 and the heating element 202 to form a stable heat conduction path, ensuring that heat can be efficiently transferred from the heating element 202 to the heat spreader 108 and then to the hydrophilic membrane assembly 101.

[0094] In some embodiments, optionally, the side of the heat spreader 108 facing the hydrophilic membrane assembly 101 is flat, and the flat design ensures that the contact surface between the heat spreader 108 and the hydrophilic membrane assembly 101 is completely flat, maximizing the thermal contact area, reducing the contact thermal resistance, and thus improving the heat conduction efficiency.

[0095] Of course, the flat design enables the hydrophilic membrane assembly 101 to be more easily docked with the heat spreader 108 during the assembly process, ensuring accurate positioning and simplifying the installation steps.

[0096] In addition, the planar contact enhances the heat conduction capability of the heat spreader 108 to the hydrophilic membrane assembly 101, so that the heat generated by the heating element 202 can be quickly and effectively transferred to the hydrophilic membrane 102 for heat dissipation. By ensuring good contact between the plane of the heat spreader 108 and the hydrophilic membrane assembly 101, local overheating due to poor contact is avoided, thereby improving the reliability and efficiency of the overall heat dissipation system.

[0097] In some embodiments, optionally, Figure 4 As shown, a mounting opening 1162 is opened on the shell 116, and the heat spreader 108 is set at the mounting opening 1162 through the sealing member 112. The sealing member 112 is set between the wall surface of the heat spreader 108 and the shell 116, and the shape of the sealing member 112 is limited to be adapted to the mounting opening 1162, so as to seal the gap between the mounting opening 1162 and the heat spreader 108. When dissipating heat, the possibility of generating condensed water can be effectively reduced, thereby improving the safety of the equipment using the heat dissipation component.

[0098] It should be added that the hydrophilic membrane assembly 101 is closely attached to the upper surface of the vapor chamber 108 and can be fixed by a thermally conductive material or adhesive. This direct connection ensures that heat can be quickly transferred to the hydrophilic membrane assembly 101 through the vapor chamber 108, thereby optimizing the heat dissipation effect. The seal 112 surrounds the edge of the vapor chamber 108, and its specific shape matches the shape of the mounting opening 1162, so that the gap between the mounting opening 1162 and the vapor chamber 108 is effectively sealed, thereby preventing the leakage of moisture and gas and improving the heat dissipation efficiency.

[0099] 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 from 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] Among them, energy storage equipment includes but is not limited to energy storage batteries, energy storage inverters and other equipment.

[0104] like Figure 8 and Fig. 9 As shown, Figure 8 A temperature schematic diagram showing an energy storage device operating under a first condition according to an embodiment of the utility model is shown; Figure 8 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 Figure 8 The temperature of the highest point in the middle part of the left structure is significantly lower than Fig. 9 The temperature at the highest point in the temperature is clearly visible from the color Figure 8 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.

[0105] like Fig.10 and Fig.11 As shown, Fig.10 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.11 The temperature diagram of the energy storage device without heat dissipation components under the same second condition is shown. Fig.10 The temperature of the highest point in the middle part of the left structure is significantly lower than Fig.11 The temperature at the highest point in the temperature is clearly visible from the color Fig.10 The color is darker, and the heat dissipation effect of the hydrophilic membrane component in this scheme is better.

[0106] In general, according to the solution of the present application, under the action of the heat spreader, the heat generated by the heating element is evenly dispersed to the entire board surface to avoid local overheating. On this basis, the hydrophilic membrane component disperses the heat to the whole through contact with the heat spreader, so that the entire hydrophilic membrane component dissipates heat together, thereby improving the overall heat dissipation efficiency.
