[0002] As a core power component of new energy vehicles, lithium-ion battery packs have become increasingly important in recent years due to the global emphasis on environmental protection and sustainable development, as well as the rapid development of the new energy vehicle market. With its advantages such as high energy density, high voltage platform, long cycle life, and relatively low self-discharge rate, lithium-ion battery packs have become the preferred power source for new energy vehicles, providing continuous and stable power support and effectively meeting the requirements of new energy vehicles for driving range and performance.

[0003] However, in practical applications, new energy lithium battery packs face numerous challenges, among which the heat dissipation problem is particularly prominent. Because the battery packs of new energy vehicles operate continuously during driving, heat can easily accumulate, leading to battery pack damage and potentially causing serious safety accidents such as short circuits and fires, posing a significant threat to the lives and property of drivers and passengers. Utility Model Content

[0004] The main purpose of this utility model is to propose a heat dissipation structure and a heat dissipation battery pack, which aims to solve the problem that when a new energy vehicle is in operation, the battery pack is in a state of long-term operation, which can easily cause heat accumulation, leading to battery pack damage, and may even cause serious safety accidents such as battery short circuits and fires.

[0005] To achieve the above objectives, the present invention proposes a heat dissipation structure, which includes a heat dissipation component. The heat dissipation component includes a heat dissipation body and a heat-conducting plate. The heat-conducting plate is used to connect the battery pack and transfer the heat generated by the battery pack. The heat dissipation body and the heat-conducting plate enclose a heat dissipation cavity. The heat-conducting plate can transfer the heat generated by the battery pack to the heat dissipation cavity.

[0006] In one embodiment, the heat dissipation body has an air inlet and an air outlet, both of which are located on the side wall of the heat dissipation body and are connected to the heat dissipation cavity and the outside.

[0007] In one embodiment, the heat dissipation assembly has a heat sink connected to the heat conduction plate and the heat dissipation body, and the heat sink is arranged along the direction from the air inlet to the air outlet.

[0008] In one embodiment, the heat dissipation assembly includes a plurality of heat sinks, each heat sink being connected to the heat conduction plate and the heat dissipation body, and all the heat sinks being arranged along the direction from the air inlet to the air outlet.

[0009] In one embodiment, the heat dissipation assembly includes a liquid storage tank, a cooling pipe, and a circulation pump. Both ends of the cooling pipe are connected to the liquid storage tank, and the circulation pump connects the liquid storage tank and the cooling pipe, enabling the coolant in the liquid storage tank to circulate within the cooling pipe.

[0010] In one embodiment, the cooling pipe is arranged in a spiral shape on the heat dissipation body, and the cooling pipe is located inside the heat dissipation cavity.

[0011] In one embodiment, the heat dissipation structure further includes a protective member connected to the heat dissipation body, the protective member being located on the side of the heat dissipation body facing away from the heat-conducting plate.

[0012] In one embodiment, a protective cavity is formed within the protective member, and the heat dissipation structure further includes a buffer member located within the protective cavity and abutting against the inner wall of the protective cavity.

[0013] In one embodiment, the buffer member has at least two buffer plates protruding from it, each of the buffer plates being connected to the protective member, and the two opposing buffer plates being arranged at an obtuse angle.

[0014] This utility model also proposes a heat dissipation battery pack, including a heat dissipation structure.

[0015] The heat dissipation structure of this utility model mainly includes a heat dissipation component, which consists of a heat dissipation body and a heat-conducting plate. The heat dissipation body and the heat-conducting plate enclose a heat dissipation cavity. The heat-conducting plate is used to connect the battery pack and transfer the heat generated by the battery pack to the heat dissipation cavity. For example, the heat-conducting plate can be made of a metal material with high thermal conductivity (such as aluminum alloy or copper alloy), with one side tightly attached to the battery pack and the other side in contact with the heat dissipation body. The heat dissipation body can be designed with a structure with multiple heat dissipation fins to increase the heat dissipation area and improve heat dissipation efficiency. In practical applications, the heat dissipation cavity can also be filled with a thermally conductive medium (such as thermally conductive silicone grease or coolant) to further enhance heat conduction and dissipation. This heat dissipation structure can effectively solve the problem of damage and safety hazards caused by heat accumulation in new energy vehicle battery packs during driving. By quickly transferring the heat generated by the battery pack to the heat dissipation cavity through the heat-conducting plate and using the heat dissipation body for efficient heat dissipation, the temperature of the battery pack is significantly reduced.

[0027] This utility model proposes a heat dissipation structure 100.

[0028] Please see Figures 1 to 3 In one embodiment of the present invention, the heat dissipation structure 100 includes a heat dissipation component 1, which includes a heat dissipation body 11 and a heat conduction plate 12. The heat conduction plate 12 is used to connect the battery pack and transfer the heat generated by the battery pack. The heat dissipation body 11 and the heat conduction plate 12 enclose a heat dissipation cavity 1a. The heat conduction plate 12 can transfer the heat generated by the battery pack to the heat dissipation cavity 1a.

[0029] The heat dissipation structure 100 of this utility model mainly includes a heat dissipation component 1, which consists of a heat dissipation body 11 and a heat-conducting plate 12. The heat dissipation body 11 and the heat-conducting plate 12 enclose a heat dissipation cavity 1a. The heat-conducting plate 12 is used to connect the battery pack and transfer the heat generated by the battery pack to the heat dissipation cavity 1a. For example, the heat-conducting plate 12 can be made of a metal material with high thermal conductivity (such as aluminum alloy or copper alloy), with one side tightly attached to the battery pack and the other side in contact with the heat dissipation body 11. The heat dissipation body 11 can be designed with a structure with multiple heat dissipation fins to increase the heat dissipation area and improve heat dissipation efficiency. In practical applications, the heat dissipation cavity 1a can also be filled with a thermally conductive medium (such as thermally conductive silicone grease or coolant) to further enhance heat conduction and dissipation. This heat dissipation structure 100 can effectively solve the problem of damage and safety hazards caused by heat accumulation in the battery pack of new energy vehicles during driving. By quickly transferring the heat generated by the battery pack to the heat dissipation cavity 1a through the heat-conducting plate 12 and using the heat dissipation body 11 for efficient heat dissipation, the temperature of the battery pack is significantly reduced.

[0030] In one embodiment of this utility model, please refer to Figure 2 and Figure 3The heat dissipation body 11 has an air inlet 1b and an air outlet 1c. Both the air inlet 1b and the air outlet 1c are located on the side wall of the heat dissipation body 11, and both the air inlet 1b and the air outlet 1c are connected to the heat dissipation cavity 1a and the outside.

[0031] In this embodiment, the heat dissipation body 11 has an air inlet 1b and an air outlet 1c, both of which are located on its sidewall and connected to the heat dissipation cavity 1a. This design allows the heat dissipation body 11 to introduce external air or cooling medium through the air inlet 1b and exhaust the heated air or cooling medium through the air outlet 1c, thereby achieving rapid heat transfer and dissipation. For example, the air inlet 1b and air outlet 1c can be located on opposite sides of the sidewall of the heat dissipation body 11 to form a good airflow channel. The air inlet 1b can be designed as multiple small holes or a large opening to increase the air intake; the air outlet 1c can be designed as one or more openings to ensure that heat can be smoothly discharged. In practical applications, a fan or other forced convection device can also be installed on the sidewall of the heat dissipation body 11 to further enhance airflow and improve heat dissipation efficiency. For example, a small axial fan can be installed at the air inlet 1b, and the air intake can be adjusted by controlling the fan speed, thereby achieving precise control of heat dissipation efficiency. Furthermore, the sidewalls of the heat dissipation body 11 can be designed with a certain angle of inclination to guide the flow direction of air or cooling medium. For example, the air inlet 1b can be designed to be inclined upwards, and the air outlet 1c can be designed to be inclined downwards. This allows the cooling medium to form natural convection within the heat dissipation cavity 1a by utilizing gravity, further improving the heat dissipation effect. Simultaneously, the sidewalls of the heat dissipation body 11 can also be provided with some guide channels or guide plates to optimize the airflow path, reduce turbulence and resistance, and improve heat dissipation efficiency. For example, multiple parallel guide channels can be provided on the sidewalls of the heat dissipation body 11, allowing air or cooling medium to smoothly flow into and out of the heat dissipation cavity 1a along the guide channels.

[0032] In one embodiment of this utility model, please refer to Figure 3 The heat dissipation component 1 has a heat sink 13, which is connected to the heat conduction plate 12 and the heat dissipation body 11. The heat sink 13 is arranged along the direction from the air inlet 1b to the air outlet 1c.

[0033] In one embodiment, the heat dissipation assembly 1 includes a heat sink 13, which connects the heat-conducting plate 12 and the heat dissipation body 11, and is positioned along the direction from the air inlet 1b to the air outlet 1c. This design allows the heat sink 13 to effectively guide the heat transferred from the heat-conducting plate 12 to the heat dissipation body 11, and dissipate it through the heat dissipation cavity 1a of the heat dissipation body 11. The heat sink 13 can be made of a high thermal conductivity material (such as aluminum alloy, copper alloy, or graphite) to ensure rapid heat conduction. For example, the heat sink 13 can be designed as multiple parallel thin sheet structures, with one end tightly attached to the heat-conducting plate 12 and the other end connected to the heat dissipation body 11. The shape and size of the heat sink 13 can be optimized according to heat dissipation requirements to improve heat dissipation efficiency. The heat sink 13 can be designed as a long strip or a wave shape to increase the heat dissipation area and airflow path. In practical applications, the heat sink 13 can be fixedly connected to the heat dissipation body 11 and the heat-conducting plate 12 by welding, riveting, or integral molding to ensure structural stability and thermal conductivity. The heat sink 13 can be connected to the heat-conducting plate 12 and the heat dissipation body 11 by welding to form an integral heat dissipation assembly 1. Furthermore, the surface of the heat sink 13 can be specially treated, such as by adding a coating or texture, to further improve the heat dissipation effect. For example, coating the surface of the heat sink 13 with a thermally conductive coating can improve its thermal conductivity; setting tiny textures on the surface of the heat sink 13 can increase airflow turbulence and improve heat dissipation efficiency.

[0034] In one embodiment of this utility model, please refer to Figure 3 The heat dissipation component 1 includes multiple heat sinks 13, each heat sink 13 is connected to a heat conduction plate 12 and a heat dissipation body 11, and all heat sinks 13 are arranged along the direction from the air inlet 1b to the air outlet 1c.

[0035] In this embodiment, the heat dissipation assembly 1 includes multiple heat sinks 13, each heat sink 13 being connected to a heat-conducting plate 12 and a heat dissipation body 11, and all heat sinks 13 are arranged along the direction from the air inlet 1b to the air outlet 1c. This design increases the heat dissipation path and heat dissipation area through multiple heat sinks 13, thereby more effectively transferring the heat generated by the battery pack to the heat dissipation body 11 and dissipating it. In specific implementations, the heat sinks 13 can be made of highly thermally conductive materials (such as aluminum alloy, copper alloy, or graphene composite material) to ensure rapid heat conduction. For example, the heat sinks 13 can be designed as a parallel arranged thin sheet structure, with one end tightly attached to the heat-conducting plate 12 and the other end connected to the heat dissipation body 11. The spacing between the heat sinks 13 can be optimized according to heat dissipation requirements to ensure smooth flow of air or cooling medium between the heat sinks 13, further improving heat dissipation efficiency. The heat sinks 13 can be fixedly connected to the heat-conducting plate 12 and the heat dissipation body 11 by welding, riveting, or bolting. The surface of the heat sinks 13 can also be specially treated, such as by adding a coating or texture, to further improve the heat dissipation effect. For example, coating the surface of the heat sink 13 with a thermally conductive coating can improve its thermal conductivity; setting tiny textures or protrusions on the surface of the heat sink 13 can increase airflow turbulence and improve heat dissipation efficiency. To further optimize the heat dissipation effect, the heat sink 13 can be designed with a wavy or sawtooth structure to increase the heat dissipation area and airflow path.

[0036] In one embodiment of this utility model, please refer to Figure 3 The heat dissipation assembly 1 includes a liquid storage tank 14, a cooling pipe 15, and a circulation pump 16. Both ends of the cooling pipe 15 are connected to the liquid storage tank 14. The circulation pump 16 is connected to the liquid storage tank 14 and the cooling pipe 15. The circulation pump 16 enables the coolant in the liquid storage tank 14 to circulate in the cooling pipe 15.

[0037] In one embodiment, the heat dissipation assembly 1 includes a liquid reservoir 14, a cooling pipe 15, and a circulation pump 16. Both ends of the cooling pipe 15 are connected to the liquid reservoir 14, forming a closed coolant circulation loop. The circulation pump 16 connects the liquid reservoir 14 and the cooling pipe 15, enabling the coolant in the liquid reservoir 14 to circulate within the cooling pipe 15, thereby achieving rapid heat transfer and dissipation. In specific implementations, the liquid reservoir 14 can be made of corrosion-resistant and high-temperature-resistant materials, such as aluminum alloy or stainless steel, to ensure its stability and reliability during long-term use. The cooling pipe 15 can be made of a material with high thermal conductivity, such as copper or aluminum, to improve the heat transfer efficiency of the coolant. The shape of the cooling pipe 15 can be designed according to the structure and heat dissipation requirements of the battery pack; for example, it can be designed as a serpentine, spiral, or other complex shape to increase the contact area between the coolant and the battery pack and improve the heat dissipation effect. The circulation pump 16 can be selected according to actual needs; for example, a small DC motor-driven centrifugal pump or gear pump can be used to meet different power and flow rate requirements. In addition, the heat dissipation assembly 1 may also include a temperature sensor and a controller for real-time monitoring of the coolant temperature and automatic adjustment of the rotation speed of the circulation pump 16 based on temperature changes. For example, when the temperature sensor detects that the coolant temperature is too high, the controller can automatically increase the rotation speed of the circulation pump 16 to accelerate the coolant circulation speed, thereby enhancing the heat dissipation effect; conversely, when the temperature decreases, the rotation speed of the circulation pump 16 can be reduced to save energy. This automatic control function ensures that the heat dissipation system is always in optimal working condition, improving heat dissipation efficiency and reliability.

[0038] In one embodiment of this utility model, please refer to Figure 3 The cooling pipe 15 is arranged in a spiral shape on the heat dissipation body 11 and is located in the heat dissipation cavity 1a.

[0039] In this embodiment, the cooling pipe 15 is spirally arranged within the heat dissipation body 11 and located within the heat dissipation cavity 1a. This design maximizes the contact area between the cooling pipe 15 and the air or other cooling medium within the heat dissipation cavity 1a, thereby improving heat dissipation efficiency. Specifically, the cooling pipe 15 can be made of a high thermal conductivity material (such as copper or aluminum alloy) to ensure that heat can be quickly transferred from the battery pack to the coolant. The spiral shape of the cooling pipe 15 can be optimized according to the internal space of the heat dissipation body 11 and the heat dissipation requirements. For example, the cooling pipe 15 can be designed as a multi-layer spiral structure, and the spacing between each spiral layer can be adjusted according to the heat dissipation requirements to ensure smooth flow of the coolant within the pipe and sufficient heat absorption. In practical applications, the cooling pipe 15 can be fixed within the heat dissipation body 11 by welding, snap-fitting, or threaded connection. For example, the cooling pipe 15 can be fixed to the inner wall of the heat dissipation body 11 by welding to ensure its stability within the heat dissipation cavity 1a.

[0040] In one embodiment of this utility model, please refer to Figure 1 The heat dissipation structure 100 also includes a protective component 2, which is connected to the heat dissipation body 11 and is located on the side of the heat dissipation body 11 away from the heat conduction plate 12.

[0041] In one embodiment, the heat dissipation structure 100 further includes a protective component 2, which is connected to the heat dissipation body 11 and located on the side of the heat dissipation body 11 opposite to the heat conduction plate 12. This design effectively protects the heat dissipation body 11 from the influence of the external environment and prevents mechanical damage to the heat dissipation body 11 during use. Specifically, the protective component 2 can be made of high-strength, corrosion-resistant materials, such as aluminum alloy, stainless steel, or engineering plastics. The protective component 2 can be fixedly connected to the heat dissipation body 11 by welding, bolting, or snap-fitting to ensure the stability and reliability of its structure. For example, the protective component 2 can be designed as a shell structure that matches the shape of the heat dissipation body 11, with its inner side tightly fitted to the heat dissipation body 11 and its outer side provided with reinforcing ribs or plates to improve the strength and rigidity of the protective component 2. In practical applications, the protective component 2 can also be designed to have a certain ventilation function to ensure that the heat dissipation performance of the heat dissipation body 11 is not affected. For example, the surface of the protective component 2 can be provided with multiple ventilation holes or ventilation slots. These ventilation holes or ventilation slots can communicate with the heat dissipation cavity 1a of the heat dissipation body 11, allowing air to flow smoothly through the heat dissipation body 11, thereby improving heat dissipation efficiency. In addition, a layer of heat insulation material can be provided between the protective component 2 and the heat dissipation body 11 to prevent external heat from adversely affecting the heat dissipation body 11. For example, filling a layer of heat insulation foam or heat insulation felt between the protective component 2 and the heat dissipation body 11 can effectively reduce the conduction of external heat and further improve the performance of the heat dissipation structure 100.

[0042] In one embodiment of this utility model, please refer to Figure 4 The protective component 2 has a protective cavity 2a formed inside it. The heat dissipation structure 100 also includes a buffer component 3, which is located inside the protective cavity 2a and abuts against the inner wall of the protective cavity 2a.

[0043] In this embodiment, a protective cavity 2a is formed inside the protective member 2, and the heat dissipation structure 100 also includes a buffer member 3, which is located inside the protective cavity 2a and abuts against the inner wall of the protective cavity 2a. This design, through the buffer member 3, can effectively absorb and disperse the impact force of the external environment on the heat dissipation body 11, thereby protecting the heat dissipation body 11 from mechanical damage. Specifically, the buffer member 3 can be made of a material with good elasticity and cushioning properties, such as silicone, sponge, polyurethane foam, or rubber. The buffer member 3 can be designed with a structure that matches the shape of the inner wall of the protective cavity 2a, such as a block, sheet, or ring, to ensure that it can fit tightly against the inner wall of the protective cavity 2a. The buffer member 3 can be fixed in the protective cavity 2a by means of bonding, snap-fit, or interference fit.

[0044] In one embodiment of this utility model, please refer to Figure 1 and Figure 4 The buffer 3 has at least two buffer plates 31 protruding from it, and each buffer plate 31 is connected to the protective member 2. The two opposing buffer plates 31 are set at an obtuse angle.

[0045] In one embodiment, at least two buffer plates 31 protrude from the buffer member 3, each buffer plate 31 being connected to the protective member 2, and the two opposing buffer plates 31 being arranged at an obtuse angle. This design allows the buffer plates 31 to disperse and absorb impact forces through their obtuse angle structure when subjected to external impacts, thereby better protecting the heat dissipation body 11 from mechanical damage. Specifically, the buffer plates 31 can be made of the same material as the buffer member 3, such as silicone, sponge, polyurethane foam, or rubber, to ensure good elasticity and cushioning performance. The buffer plates 31 can be connected to the buffer member 3 by means of bonding, snap-fitting, or integral molding, and fixed to the protective member 2 through the buffer member 3. For example, the buffer plates 31 can be integrally molded with the buffer member 3 to form an integral buffer structure, and then the buffer member 3 can be fixed in the protective cavity 2a by bonding or snap-fitting. In practical applications, the shape and size of the buffer plates 31 can be optimized according to the structure and protection requirements of the heat dissipation body 11. For example, the buffer plates 31 can be designed as triangular, trapezoidal, or other polygonal structures to adapt to different shapes of the protective cavity 2a. The two opposing buffer plates 31 are set at an obtuse angle, which can effectively increase the contact area between the buffer plates 31 and the external impact force, thereby better dispersing the impact force. In addition, the surface of the buffer plates 31 can be specially treated, such as adding texture or coating, to improve its wear resistance and impact resistance. For example, applying a wear-resistant coating to the surface of the buffer plates 31 can extend the service life of the buffer plates 31.
