Description

Technical Field

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

[0002] Currently, energy storage devices generate a large amount of heat during operation. In related technologies, air cooling or liquid cooling is usually used for heat dissipation. During heat dissipation, condensation water is generated due to temperature differences. If it drips onto electronic components, it will affect the normal operation of the equipment. Utility Model Content

[0003] The utility model aims to at least solve the technical problem that heat dissipation condensation existing in the prior art or related art affects the normal operation of equipment.

[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 present invention provides an energy storage device.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the present utility model provides a heat dissipation component, including: a shell, a heating element is provided in the shell, and air holes are provided on the wall of the shell; a hydrophilic membrane component, the hydrophilic membrane component is provided between the heating element and the wall where the air holes are provided; a sealing component, provided between the heating element and the wall where the air holes are provided, the shape of the sealing component is adapted to the shape of the hydrophilic membrane component, and the sealing component is used to seal the gap between the heating element and the shell.

[0007] According to the heat dissipation component proposed by the utility model, it includes: a shell, a hydrophilic membrane component and a sealing component. A heating element is arranged in the shell, and air holes are provided on the wall of the shell. By arranging the hydrophilic membrane component between the heating element and the wall with the air holes, the hydrophilic membrane component absorbs moisture in the air and uses phase change to dissipate heat, thereby reducing the temperature of the heating element.

[0008] It should be emphasized that in this solution, a seal is provided between the heating element and the wall where the air vent is provided. The shape of the seal is adapted to the shape of the hydrophilic membrane assembly and is usually made of a flexible material. It is used to seal the gap between the heating element and the shell. When dissipating heat, it can effectively reduce the possibility of condensation water inside the shell, thereby improving the safety of use of equipment using the heat dissipation assembly.

[0009] It should be noted that the hydrophilic membrane assembly is closely attached to the surface of the heating element and can be fixed with thermally conductive materials or adhesives. This direct connection ensures that heat is quickly transferred to the hydrophilic membrane, optimizing the heat dissipation effect. The seal surrounds the edge of the hydrophilic membrane assembly, effectively sealing the gap between the heating element and the housing, preventing moisture and gas leakage and improving heat dissipation efficiency.

[0010] Among them, the air vents are arranged on the wall of the shell, allowing air to flow, providing a path for heat release and air circulation, and enhancing the heat dissipation capacity of the heat dissipation component.

[0011] In some technical solutions, optionally, the shell specifically includes: a box body and a cover body, and the cover body is provided with the air vent; wherein the sealing member is provided on the cover body and / or the box body.

[0012] In this technical solution, the shell includes at least two parts: a box body and a cover body. By setting air holes on the cover body and selectively setting a seal on at least one of the cover body and the box body, the hydrophilic membrane assembly is sealed, effectively reducing the gap between the hydrophilic membrane assembly and the shell, and reducing the possibility of generating condensation water.

[0013] Furthermore, in this solution, the seal is arranged between the cover and the box, specifically at the edge where the cover and the box contact, and is arranged around the periphery of the entire cover to ensure that every point where the cover and the box are connected can be effectively sealed.

[0014] One side of the seal fits snugly against the edge of the cover, and when the cover is assembled onto the box, the other side of the seal fits snugly against the upper edge of the box. During installation, the cover presses against the box, compressing the seal and filling the gap between the cover and the box, achieving a sealing effect.

[0015] In some technical solutions, optionally, a sealing member is provided on a side of the cover body facing the box body, and the hydrophilic membrane assembly is in contact with the cover body.

[0016] In this technical solution, the seal is arranged on the cover body, specifically on the side of the cover body facing the box body. By attaching the hydrophilic membrane component to the cover body and covering the inner side of the air vent, it is ensured that heat can evaporate and absorb the water in the hydrophilic membrane component, and dissipate heat through the air vent.

[0017] During installation, first attach the hydrophilic membrane assembly to the inside of the cover, ensuring it covers the vents. Install the seal on the side of the cover facing the box, ensuring it fits snugly against the edges of the cover and box. Finally, place the cover over the box and secure it to the box using fasteners (such as screws or clips), ensuring the seal is fully compressed to achieve a seal.

[0018] In some technical solutions, optionally, a receiving groove is provided on the wall where the air vent is provided, the shape of the receiving groove is adapted to the shape of the sealing component, and the sealing component is embedded in the receiving groove.

[0019] In this technical solution, a receiving groove, shaped to match the seal, is provided on the wall where the vent is located. The groove allows the seal to be embedded within the groove. This design provides a dedicated space for the seal to be securely fixed to the housing wall, minimizing displacement or dislodging caused by vibration or temperature fluctuations. Furthermore, since the shape of the receiving groove matches the seal, and the seal's shape matches the hydrophilic membrane assembly, installation of the three components is simplified, allowing users to easily disassemble and reinstall them for maintenance or replacement, reducing operational complexity.

[0020] Furthermore, the receiving groove is located on the inner surface of the wall of the shell, forming a special groove structure. During assembly, the receiving groove can be used as an assembly object for the seal, and the seal and the hydrophilic membrane assembly embedded in the seal can be directly installed into the receiving groove, thereby reducing the installation difficulty and improving the installation efficiency.

[0021] In some technical solutions, optionally, the sealing member respectively abuts against the groove wall of the accommodating groove and the wall where the air vent is provided.

[0022] In this technical solution, the seal is pressed against the groove wall of the accommodating groove and the wall of the shell, which can effectively seal the gap of the accommodating groove. Specifically, one side of the seal is pressed against the wall of the shell, and the other side is pressed against the groove wall of the accommodating groove, thereby achieving sealing.

[0023] In some technical solutions, optionally, the hydrophilic membrane assembly includes: a hydrophilic membrane; and a waterproof and breathable membrane, which is arranged on one side of the hydrophilic membrane.

[0024] In this technical solution, the hydrophilic membrane assembly includes a hydrophilic membrane and a waterproof breathable layer that are stacked, wherein the hydrophilic membrane is located in the middle, on one side of the waterproof breathable membrane, and the waterproof breathable membrane is arranged on the outside. It can be understood that the hydrophilic membrane continuously absorbs moisture in the air. When the surface temperature of the object that needs to dissipate heat rises, the heat can be conducted to the hydrophilic membrane by contacting the hydrophilic membrane assembly with it. The water changes 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.

[0025] In some technical solutions, optionally, it further includes: a heat-conducting layer, which is provided on the other side of the hydrophilic film, and the heat-conducting layer is in contact with the heating element.

[0026] By placing the thermally conductive layer on one side of the hydrophilic membrane, in direct contact with the membrane, the thermally conductive layer can be made of silicone or other thermally conductive materials, optionally with a thermally conductive adhesive layer, effectively transferring heat from the heat source to the hydrophilic membrane, allowing water to evaporate. The waterproof and breathable membrane, placed on one side of the thermally conductive layer, provides waterproof and breathable properties, preventing the ingress of external liquid water while maintaining a dry interior and allowing the passage of vaporized water formed during evaporation, maintaining effective heat dissipation.

[0027] In some technical solutions, optionally, it also includes: a first fitting part, which is arranged on the same wall of the shell as the air vent; a second fitting part, which is arranged on the hydrophilic membrane assembly; wherein the relative position of the hydrophilic membrane assembly and the shell is limited by the cooperation of the first fitting part and the second fitting part.

[0028] In this technical solution, a first fitting part and a second fitting part are provided, and the first fitting part is provided on the same wall as the air vent, and the second fitting part is provided on the hydrophilic membrane assembly. By cooperating with the two, the position and fixation of the hydrophilic membrane assembly are ensured.

[0029] It can be understood that the design of these two fittings allows the hydrophilic membrane assembly to be assembled to the housing quickly and accurately, reducing assembly time and complexity, improving production efficiency, and lowering the skill requirements for assemblers.

[0030] By connecting the first fitting and the second fitting, close contact between the shell and the hydrophilic membrane 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 hydrophilic membrane assembly, thereby improving the heat dissipation effect.

[0031] Ensure the fixed position of the hydrophilic membrane 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.

[0032] In some technical solutions, optionally, the first fitting member and the second fitting member are magnetically connected.

[0033] In this technical solution, the first fitting and the second fitting are connected by threads, providing higher connection strength and stability, ensuring a tight connection between the hydrophilic membrane assembly and the shell, and preventing displacement or loosening due to vibration or temperature changes.

[0034] Of course, users can adjust the tightness of the connection by rotating it, which is convenient for fine-tuning during assembly and maintenance to ensure the best fit.

[0035] Alternatively, the first fitting and the second fitting 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 hydrophilic membrane component and the shell is guided to a certain extent, making the assembly and disassembly of the hydrophilic membrane component and the shell faster and more convenient, reducing operation time and labor intensity.

[0036] Furthermore, since magnetic connections do not rely on physical locking, they avoid the wear and tear that can occur with threaded connections, extending the life of the component. Understandably, magnetic connections allow for a certain degree of movement and adjustment, adapting to expansion or contraction caused by temperature changes and maintaining a good connection.

[0037] Whether using a threaded or magnetic connection, the design of the first and second fittings provides a flexible and reliable connection solution for the heat dissipation assembly. The threaded connection enhances connection strength and reliability, while the magnetic connection provides the convenience of quick assembly and disassembly, meeting the needs of different users and improving the overall user experience.

[0038] An embodiment of a second aspect of the present application provides an energy storage device, comprising: any of the above-mentioned heat dissipation components;

[0039] 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 utilized 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.

[0040] It should be emphasized that for the working scenario of the battery of the energy storage device, the intermittent working characteristics of the hydrophilic membrane 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 can gradually absorb water vapor in the environment to meet subsequent heat dissipation needs.

[0041] It can be understood that under the action of the hydrophilic membrane, water can be automatically replenished when the battery is working intermittently, maintaining heat dissipation performance and reducing manual intervention.

[0042] 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 the water vapor in the environment to meet the subsequent heat dissipation needs.

[0043] It can be understood that under the action of the hydrophilic membrane component, the heat dissipation of the battery is ensured and the maintenance cost is reduced.

[0065] 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, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0066] 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.

[0067] Refer to the following Figures 1 to 15 Some embodiments according to the present invention are described.

[0068] like Figure 1 As shown, this embodiment provides a heat dissipation component 100, including: a shell 108, a hydrophilic membrane component 101 and a sealing component 110. A heating element is arranged in the shell 108, and an air vent 1082 is provided on the wall of the shell 108. By arranging the hydrophilic membrane component 101 between the heating element and the wall where the air vent 1082 is provided, the hydrophilic membrane component 101 absorbs moisture in the air and dissipates heat by phase change, thereby reducing the temperature of the heating element.

[0069] It should be emphasized that in this solution, a seal 110 is provided between the heating element and the wall where the air vent 1082 is provided. The shape of the seal 110 is adapted to the shape of the hydrophilic membrane assembly 101 and is usually made of a flexible material. It is used to seal the gap between the heating element and the shell 108. When dissipating heat, it can effectively reduce the possibility of condensation water generated inside the shell 108, thereby improving the safety of use of equipment using the heat dissipation assembly 100.

[0070] It should be noted that the hydrophilic membrane assembly 101 is closely attached to the surface of the heating element and can be fixed by thermally conductive materials or adhesives. This direct connection ensures that heat can be quickly transferred to the hydrophilic membrane 102, optimizing the heat dissipation effect. The seal 110 surrounds the edge of the hydrophilic membrane assembly 101, effectively sealing the gap between the hydrophilic membrane assembly 101 and the housing 108, preventing the leakage of water and gas, and improving the heat dissipation efficiency.

[0071] The air holes 1082 are provided on the wall of the housing 108 , allowing air to flow, providing a path for heat release and air circulation, and enhancing the heat dissipation capability of the heat dissipation assembly 100 .

[0072] In some embodiments, optionally, as Figure 7 As shown, the shell 108 includes at least two parts: a box body 1084 and a cover body 1086. By setting a vent hole 1082 on the cover body 1086 and selectively setting the seal 110 on at least one of the cover body 1086 and the box body 1084, the hydrophilic membrane assembly is sealed, the gap between the hydrophilic membrane assembly and the shell is effectively reduced, and the possibility of generating condensed water is reduced.

[0073] Furthermore, in this solution, the seal 110 is arranged between the cover 1086 and the box 1084, specifically at the edge where the cover 1086 and the box 1084 contact each other, and is arranged around the periphery of the entire cover 1086 to ensure that every point of the connection between the cover 1086 and the box 1084 can be effectively sealed.

[0074] One side of the seal 110 abuts against the edge of the cover 1086. When the cover 1086 with the seal 110 is assembled onto the box, the other side of the seal 110 abuts against the upper edge of the box 1084. During installation, the cover 1086 presses against the box 1084, compressing the seal 110 and filling the gap between the cover 1086 and the box 1084 to achieve a sealing effect.

[0075] Furthermore, the seal 110 is arranged on the cover body 1086, specifically on the side of the cover body 1086 facing the box body 1084. By attaching the hydrophilic membrane assembly 101 to the cover body 1086 and covering the inner side of the air vent 1082, it is ensured that heat can evaporate and absorb heat from the water in the hydrophilic membrane assembly 101, and dissipate heat through the air vent 1082.

[0076] During installation, first fit the hydrophilic membrane assembly 101 against the inside of the cover 1086, ensuring that it covers the vents 1082. Install the seal 110 on the side of the cover 1086 facing the box 1084, ensuring that it fits tightly against the edges of the cover 1086 and the box 1084. Finally, place the cover 1086 over the box 1084 and secure it to the box 1084 using a fastener (such as a screw or snap), ensuring that the seal 110 is fully compressed to achieve a sealing effect.

[0077] In some embodiments, optionally, as Figure 8 As shown, a receiving groove 1088 is provided on the wall where the vent hole 1082 is provided, which is adapted to the shape of the sealing member 110. Figure 9 As shown, the seal 110 can be embedded in the receiving groove 1088. The design of the receiving groove 1088 provides a dedicated space so that the seal 110 can be firmly fixed to the wall of the housing 108, reducing displacement or separation caused by vibration or temperature changes. In addition, because the shape of the receiving groove 1088 is compatible with the seal 110, and the shape of the seal 110 is compatible with the hydrophilic membrane assembly 101, the installation of the three is more convenient. Users can also easily disassemble and reinstall them during maintenance or replacement, reducing the difficulty of operation.

[0078] Furthermore, the receiving groove 1088 is located on the inner surface of the wall of the shell 108, forming a special groove structure. During assembly, the receiving groove 1088 can be used as an assembly object of the seal 110, and the seal 110 and the hydrophilic membrane assembly 101 embedded in the seal 110 can be directly installed into the receiving groove 1088, thereby reducing the difficulty of installation and improving the installation efficiency.

[0079] Among them, such as Figure 9 As shown, the two sides of the seal 110 are pressed against the groove wall of the accommodating groove 1088 and the wall of the shell 108, which can effectively seal the gap of the accommodating groove 1088. Specifically, one side of the seal 110 is pressed against the wall of the shell 108, and the other side is pressed against the groove wall of the accommodating groove 1088, thereby achieving sealing.

[0080] In some embodiments, optionally, as Figure 2 、 Figure 3 As shown, the hydrophilic membrane assembly 101 includes: a hydrophilic membrane 102; and a waterproof and breathable membrane 106, which is arranged on one side of the hydrophilic membrane 102.

[0081] In this embodiment, the hydrophilic membrane assembly 101 includes a hydrophilic membrane 102 and a waterproof breathable membrane 106 that are stacked, wherein the hydrophilic membrane 102 is located in the middle, on one side of the waterproof breathable membrane 106. It can be understood that the hydrophilic membrane 102 continuously absorbs moisture in the air. When the surface temperature of the object that needs to dissipate heat rises, the heat can be conducted to the hydrophilic membrane 102 by bringing the heat dissipation assembly 100 into contact with it. The heat is taken away by the water changing from liquid to gas, and the heat is dissipated by 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.

[0082] Furthermore, if Figure 15 As shown, a heat-conducting layer 104 can be provided on one side of the hydrophilic membrane 102, in direct contact with the hydrophilic membrane 102. The heat-conducting layer 104 can be made of silicone or other thermally conductive materials, and can effectively transfer heat from the heat source to the hydrophilic membrane 102, thereby evaporating water. A waterproof and breathable membrane 106 is provided on the other side of the hydrophilic membrane 102. It has waterproof and breathable properties, preventing the ingress of external liquid water, keeping the interior dry, and allowing the vaporized water formed by evaporation to pass through, maintaining a good heat dissipation effect.

[0083] In some embodiments, optionally, as Figure 4 As shown, a first fitting part 1142 and a second fitting part 1144 are provided, and the first fitting part 1142 is provided on the same wall as the air vent 1082, and the second fitting part 1144 is provided on the hydrophilic membrane assembly 101. Through the mutual cooperation between the two, the position and fixation of the hydrophilic membrane assembly 101 are ensured.

[0084] By connecting the first fitting 1142 and the second fitting 1144, close contact between the shell 108 and the hydrophilic membrane assembly 101 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 hydrophilic membrane assembly 101, thereby improving the heat dissipation effect.

[0085] Ensure that the hydrophilic membrane assembly 101 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.

[0086] In some embodiments, optionally, the first mating piece 1142 and the second mating piece 1144 are magnetically connected.

[0087] The first fitting part 1142 and the second fitting part 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 hydrophilic membrane component 101 and the shell 108 is guided to a certain extent, making the assembly and disassembly of the hydrophilic membrane component 101 and the shell 108 faster and more convenient, reducing operation time and labor intensity.

[0088] In addition, since the magnetic connection does not rely on physical locking, it avoids wear or damage that may be caused by threaded connections, thereby extending the service life of the component. It can be understood that the magnetic connection allows a certain degree of displacement and adjustment, can adapt to the expansion or contraction caused by temperature changes, and maintain a good connection state. In a specific embodiment, the first mating part 1142 is a card slot structure, and the second mating part 1144 is a slider structure, and the slider structure is arranged in the card slot structure. It can be understood that through the design of these two mating parts, the hydrophilic membrane assembly 101 and the shell 108 can be assembled quickly and accurately, reducing assembly time and complexity, improving production efficiency, and reducing the skill requirements of the assembler.

[0089] In some embodiments, optionally, as Figure 5 As shown, it also includes: a switch structure 120, which is movably connected to the wall where the air hole 1082 is set, and the switch structure 120 is used to open and close the air hole 1082, wherein the switch structure 120 includes a flat plate and two correspondingly set slide grooves, the two slide grooves are set on the outer wall of the shell 108 away from the hydrophilic membrane component 101, and the flat plate is slidably set in the two slide grooves to open and close the air hole 1082.

[0090] In this embodiment, a switch mechanism 120 is provided and movably connected to the wall of the housing 108, enabling flexible opening and closing of the vent 1082. Through the movement of the switch mechanism 120, the user can flexibly adjust the opening and closing state of the vent 1082 as needed, thereby controlling internal air flow and water vapor release, optimizing heat dissipation performance. When heat dissipation is not required for an extended period, the vent 1082 can be closed, effectively preventing the intrusion of external dust, dirt, and liquid water.

[0091] To meet different heat dissipation requirements, users can flexibly adjust the number of open and closed air holes 1082, that is, the open and closed state of each air hole 1082, so that the heat dissipation system can better adapt to changes in the external environment and improve overall performance.

[0092] The connection between the switch structure 120 and the wall of the housing 108 may be a sliding connection, a rotating connection, a magnetic connection, or the like.

[0093] In some embodiments, optionally, as Figure 5 As shown, it also includes: a filter 122, which is arranged in the air vent 1082.

[0094] In this embodiment, by setting a filter 122 inside or outside the air vent 1082, by utilizing its good air permeability and filtering ability, it can effectively block dust, dirt and other particulate matter, prevent them from entering the internal components through the air vent 1082, and protect the hydrophilic membrane 102 and other key components.

[0095] Specifically, the filter 122 can be directly embedded in or fixed on the inner side of the air vent 1082 to form a protective barrier. This connection ensures that the filter 122 can effectively intercept pollutants entering the air vent 1082 without affecting the flow of air and water vapor.

[0096] It can be understood that the filter 122 can effectively filter external pollutants, ensure the cleanliness of the internal environment, and maintain the performance and safety of the equipment.

[0097] like Figure 6 and Figure 10 As 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 the box, 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.

[0098] It should be emphasized that, in the operating scenario of the battery of energy storage device 200, the hydrophilic membrane assembly 101 can be used to dissipate heat from the battery during charging and discharging. When the battery is not charging or discharging, the hydrophilic membrane assembly 101 can gradually absorb moisture from the surrounding environment to meet subsequent heat dissipation requirements. Energy storage devices include, but are not limited to, energy storage batteries, energy storage inverters, and other devices.

[0099] like Figure 11 and Figure 12 As shown, Figure 11 A temperature diagram showing an energy storage device according to an embodiment of the present invention charging at 0.5C for 1 hour at a temperature of 45°C is shown; Figure 12 The figure shows a temperature diagram of an energy storage device without a heat dissipation component and charging at 45°C for 1 hour at 0.5C. Figure 11 The temperature at the highest point in the middle of the left structure is significantly lower than Figure 12 The temperature at the highest point in the temperature is clearly visible from the color Figure 11 The color is darker. The heat dissipation effect of this solution is much greater than the heat dissipation effect of the solution without the hydrophilic membrane component due to the provision of the hydrophilic membrane component.

[0100] like Figure 13 and Figure 14 As shown, Figure 13 A temperature diagram showing an energy storage device according to an embodiment of the present invention charging at 1C for 1 hour at a temperature of 45°C is shown; Figure 14 The figure shows the temperature of the energy storage device without heat dissipation components at 45°C and 1C for 1 hour. Figure 13The temperature at the highest point in the middle of the left structure is significantly lower than Figure 14 The temperature at the highest point in the temperature is clearly visible from the color Figure 13 The color is darker, and the heat dissipation effect of the hydrophilic membrane component in this solution is better.

[0101] In this utility model, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
