[0035] As Figures 1 to 3 shown, an embodiment of the present invention provides a heat dissipation device for a blade battery, including a battery unit, a heat spreader 2, a top cooling plate 3, a bottom cooling plate 4, and heat sinks 11. The battery unit includes a plurality of blade batteries 1 arranged in an array. The heat spreader 2 is disposed on the top of the battery unit, the top cooling plate 3 is disposed on the top of the heat spreader 2, the bottom cooling plate 4 is disposed on the bottom of the battery unit, and the heat sinks 11 are disposed on the left and right sides of the battery unit.

[0036] Specifically, multiple lithium iron phosphate blade batteries 1 are arranged in parallel along the longitudinal direction to form a battery unit. The number of blade batteries 1 is selected according to the actual situation to meet the power requirements in actual use.

[0037] The heat spreader 2 can be made of a copper-based composite material. Copper itself has good thermal conductivity. Adding reinforcing phases such as high-thermal-conductivity ceramic particles can further improve the overall thermal conductivity of the material. For example, silicon carbide-reinforced copper-based composite material, where silicon carbide particles are evenly distributed in the copper matrix, effectively improves the heat conduction ability of the material and at the same time enhances the mechanical properties of the heat spreader 2, making it more durable.

[0038] The design shape of the heat spreader 2 is determined according to the shape and layout of the top of the blade battery 1. The heat spreader 2 can be designed into a shape that fits closely with it. If the top of the blade battery 1 is flat and regularly arranged, the heat spreader 2 can be designed into a flat plate shape to ensure full contact with the top of the blade battery 1; if there are some special structures or irregular arrangements on the top of the blade battery 1, the heat spreader 2 can adopt a customized special-shaped design to accurately cover the heat-generating area on the top of the blade battery 1, reduce the thermal resistance, and improve the heat transfer efficiency.

[0039] The heat spreader 2 is arranged on the top of the battery unit, which can evenly distribute the heat generated at the top of the blade battery 1, avoid heat concentration in a certain place, and thus effectively prevent the impact of local overheating on the normal use of the blade battery 1. For example, when the blade battery 1 is charging and discharging, different amounts of heat are generated at different positions on the top. The heat spreader 2 can quickly spread these heats, making the top temperature relatively uniform.

[0040] Both the top cooling plate 3 and the bottom cooling plate 4 contain coolant inside. The coolant can be water-based coolant, organic coolant, or high-thermal-conductivity coolant, etc.

[0041] The top cooling plate 3 is located on the top of the heat spreader 2, and the bottom cooling plate 4 is arranged at the bottom of the battery unit. The top cooling plate 3 and the bottom cooling plate 4 work together to achieve the heat absorption and dissipation effects on the top and bottom of the battery unit. When the blade battery 1 generates heat during operation, the heat is first transferred to the heat spreader 2. After the heat spreader 2 distributes the heat evenly, the top cooling plate 3 and the bottom cooling plate 4 absorb the heat through heat conduction.

[0042] The top cooling plate 3 and the bottom cooling plate 4 can be made of aluminum alloy or copper alloy, so as to have good thermal conductivity and corrosion resistance. Between the top cooling plate 3 and the heat pipe vapor chamber 2, and between the bottom cooling plate 4 and the blade battery 1, thermal conductive adhesive can be used for connection. The thermal conductive adhesive has good thermal conductivity and bonding properties, which can ensure efficient heat transfer while guaranteeing the stability of the connection. In addition, mechanical connection methods can also be used, such as fixing the cooling plate to the heat pipe vapor chamber 2 and the blade battery 1 through bolts or buckles. This method is convenient for installation and disassembly while ensuring the connection strength.

[0043] The heat sinks 11 are arranged on the left and right sides of the battery cells, and can achieve the heat absorption and dissipation effects on the left and right sides of the battery cells. The heat sinks 11 have a large surface area, and by increasing the contact area with the air, the heat dissipation is accelerated. When the heat is conducted from the blade battery 1 to the heat sinks 11, the heat is quickly dissipated into the surrounding air, thereby realizing the heat dissipation on the side of the battery cells.

[0044] In practical applications, the heat sinks 11 adopt a fin structure, and the fins are parallel and closely arranged with each other to increase the heat dissipation area. The height and spacing of the fins can be adjusted according to the actual heat dissipation requirements. At the same time, in order to better fit the side of the blade battery 1, the fins can be designed into a shape that matches the side radian of the blade battery 1 to ensure close contact and reduce the thermal resistance. The heat sinks 11 can be made of aluminum alloy material, taking advantage of its good thermal conductivity and light weight. On the surface of the fins, a layer of copper can be plated. The thermal conductivity of copper is better than that of aluminum alloy, which can further improve the heat conduction efficiency of the heat sinks 11. This material combination not only ensures the overall performance of the heat sinks 11 but also controls the cost.

[0045] By setting the top cooling plate 3 and the bottom cooling plate 4, the heat absorption and dissipation effects on the top and bottom of the battery cells can be achieved. The set heat pipe vapor chamber 2 can equalize the heat on the top of the battery cells to avoid too high heat in a certain place, which affects the normal use of the battery. The set heat sinks 11 can achieve the heat absorption and dissipation effects on the left and right sides of the battery cells. Generally speaking, on the basis of ensuring the heat equalization effect on the top of the battery cells, the comprehensiveness of the heat absorption and dissipation of the battery cells is improved, and the stability and safety of the use of the battery cells are more fully guaranteed.

[0046] In one embodiment, as Figure 3 shown, the blade battery heat dissipation device further includes a heat dissipation component, and the heat dissipation component includes a rotating shaft 12. The rotating shaft 12 is rotatably arranged inside both the top cooling plate 3 and the bottom cooling plate 4. By setting the rotating shaft 12, the rest of the heat dissipation components can be driven to rotate, thereby further improving the effect of the coolant circulating flow inside the top cooling plate 3 and the bottom cooling plate 4.

[0047] Specifically, the rotating shaft 12 is made of a material with high strength, corrosion resistance and certain toughness, such as stainless steel or aluminum alloy. The specific installation method of the rotating shaft 12 can be to process bearing installation holes at corresponding positions of the top cooling plate 3 and the bottom cooling plate 4, install the adapted bearings therein, and then pass the rotating shaft 12 through the inner ring of the bearing, so that the rotating shaft 12 can rotate smoothly in the top cooling plate 3 and the bottom cooling plate 4.

[0048] In one embodiment, if Figure 3 As shown, the heat dissipation assembly further includes a stirring blade 13 , and the stirring blade 13 is connected to the outer peripheral wall of the rotating shaft 12 .

[0049] The stirring blade 13 can be a rectangular blade or a spiral blade, and is made of a lightweight material with good corrosion resistance, such as aluminum alloy. Aluminum alloy is not only light in weight, which can reduce the load when the rotating shaft 12 rotates and reduce energy consumption, but also has good corrosion resistance, which can ensure that the blade will not be corroded and damaged under long-term immersion in the coolant, thereby ensuring the long-term stable operation of the heat dissipation component. The stirring blade 13 can be fixed to the outer peripheral wall of the rotating shaft 12 by welding, key connection or bolt connection.

[0050] When the rotating shaft 12 rotates inside the top cooling plate 3 and the bottom cooling plate 4, the stirring blades 13 connected thereto rotate accordingly. The rotation of the stirring blades 13 will have a strong disturbing effect on the coolant, causing the coolant, which originally flowed relatively smoothly, to form a turbulent state. In the turbulent state, the molecular movement of the coolant is more intense, and the heat exchange with the inner wall of the cooling plate is more sufficient, thereby greatly improving the ability of the cooling plate to absorb and transfer heat from the blade battery 1. For example, during the rapid charging process of the blade battery 1, a large amount of heat is generated. At this time, the stirring blades 13 drive the coolant to flow rapidly, which can quickly take away the heat, effectively avoiding battery overheating and ensuring the safe and stable operation of the battery.

[0051] The stirring blades 13 provided in the heat dissipation assembly significantly enhance the flow effect of the coolant and the heat dissipation efficiency of the cooling plate by working in coordination with the rotating shaft 12, thereby improving the heat dissipation performance of the entire blade battery heat dissipation device, effectively ensuring the stable operation of the blade battery 1 under various working conditions and extending the service life of the battery.

[0052] In one embodiment, a water inlet pipe 6 and a water outlet pipe 7 are provided between the top cooling plate 3 and the bottom cooling plate 4. The water inlet pipe 6 and the water outlet pipe 7 can facilitate the circulation of the coolant inside the top cooling plate 3 and the bottom cooling plate 4, thereby further improving the heat absorption and heat dissipation effect of the blade battery 1.

[0053] like Figure 1 , Figure 3As shown in the figure, a water inlet pipe 6 and a water outlet pipe 7 are fixedly connected and communicated on the same side of the top cooling plate 3 and the bottom cooling plate 4. The water inlet pipe 6 and the water outlet pipe 7 can be made of metal pipes, and the pipe diameter needs to be determined according to the overall power of the heat dissipation device, the flow rate requirement of the coolant, and the size of the coolant channel inside the cooling plate. For example, for a blade battery heat dissipation device with a relatively small power and relatively low heat dissipation requirements, water inlet pipe 6 and water outlet pipe 7 with a relatively small pipe diameter can be selected, which can not only meet the basic circulation requirements of the coolant, but also reduce costs and system complexity. For the blade battery 1 heat dissipation system of large energy storage devices or high-power electric vehicles, due to its huge heat generation and the need for a large amount of coolant to quickly circulate to remove heat, pipes with a larger pipe diameter should be selected to ensure sufficient coolant flow rate and velocity to achieve efficient heat dissipation.

[0054] The connection between the water inlet pipe 6 and the water outlet pipe 7 and the top cooling plate 3 and the bottom cooling plate 4 can be achieved by using a sealing rubber ring in cooperation with a pipe clamp for fastening. At the connection part, first put the sealing rubber ring on the port of the water inlet pipe 6 or the water outlet pipe 7, then insert the pipe into the corresponding interface of the cooling plate, and finally use the pipe clamp to tightly fix the pipe and the cooling plate. This connection method can not only ensure good sealing and prevent coolant leakage, but also facilitate installation and disassembly. During daily maintenance and repair, it is possible to conveniently replace or repair the pipe or the cooling plate. Another connection method can be welding.

[0055] In one embodiment, as Figure 1 、 Figure 3 shown, the blade battery heat dissipation device further includes a water pump 14, a water supply pipe 10, and a water extraction pipe 9. The water inlet pipe 6 is communicated with the water pump 14 through the water supply pipe 10, and the water outlet pipe 7 is communicated with the water pump 14 through the water extraction pipe 9.

[0056] Specifically, the water pump 14 can be a centrifugal pump or a gear pump, and the performance parameters of the water pump 14 need to be reasonably selected according to the actual requirements of the blade battery heat dissipation device. For example, according to the heat generation power of the blade battery 1, the heat dissipation area of the cooling plate, and the flow rate requirement of the coolant, the lift and flow rate of the water pump 14 are determined. For a blade battery 1 with a relatively large power, a water pump 14 with a higher lift and a larger flow rate needs to be selected to ensure that the coolant can overcome the pipe resistance and quickly circulate inside the cooling plate.

[0057] The water supply pipe 10 and the water extraction pipe 9 are made of materials with good corrosion resistance and a certain pressure resistance, such as engineering plastics or metal pipes. The connection between the water supply pipe 10 and the water extraction pipe 9 and the water inlet pipe 6, the water outlet pipe 7, and the water pump 14 can be welding or the method of using a sealing rubber ring in cooperation with a pipe clamp for fastening.

[0058] The set water pump 14 pumps out the internal coolant through the suction pipe 9 and pumps it into the top cooling plate 3 and the bottom cooling plate 4 through the water supply pipe 10, so as to achieve continuous transportation and improve the circulating flow effect of the internal coolant in the top cooling plate 3 and the bottom cooling plate 4. At the same time, when the water pump 14 pumps the coolant into the top cooling plate 3 and the bottom cooling plate 4, the flowing coolant can drive the stirring blades 13 to rotate, thereby further improving the stirring effect of the coolant and enhancing the heat absorption and dissipation effect of the blade battery 1.

[0059] In one embodiment, as Figure 1 、 Figure 3 shown, the blade battery heat dissipation device further includes a protective cover 8, and the water pump 14 is arranged inside the protective cover 8. The protective cover 8 can be made of engineering plastics, such as ABS plastics. The protective cover 8 is provided with ventilation holes to ensure good heat dissipation when the water pump 14 is working.

[0060] The provided protective cover 8 can effectively prevent dust, sundries, etc. from entering the inside of the water pump 14, avoiding the failure of the water pump 14 caused by foreign objects. At the same time, it can reduce the physical damage of the external environment to the water pump 14. In addition, the protective cover 8 can also play a certain sound insulation role and reduce the impact of the noise generated by the water pump 14 during operation on the surrounding environment.

[0061] In one embodiment, the blade battery heat dissipation device further includes a mounting frame 5, and the mounting frame 5 is fixed to the outer surface of the battery unit. As Figure 1 shown, there are two mounting frames 5, and the two mounting frames 5 are arranged oppositely on the left and right sides of the battery unit.

[0062] The mounting frame 5 can be made of aluminum alloy material, which has the characteristics of light weight, high strength and corrosion resistance. The mounting frame 5 can be fixedly connected to the battery unit by means of bolt connection or snap connection. The setting of the mounting frame 5 enhances the stability of the battery unit and avoids displacement or shaking during its use. At the same time, the mounting frame 5 also plays a physical protection role for the battery unit, reduces the damage of external factors to the battery unit, and extends the service life of the battery unit.

[0063] In one embodiment, the mounting frame 5 includes a vertical plate portion, and an upper folding portion and a lower folding portion that extend in the same direction along the upper and lower sides of the vertical plate portion. During installation, the upper folding portion is located above the top cooling plate 3, and the lower folding portion is located below the bottom cooling plate 4.

[0064] The vertical plate part of the mounting frame 5 mainly serves to support and fix the heat sink 11. Some mounting holes can be provided on the surface of the vertical plate part for mounting the heat sink 11, so that the heat sink 11 is closely attached to the side of the battery unit, effectively improving the heat dissipation efficiency. For example, a number of threaded holes are evenly distributed on the vertical plate part, and the heat sink 11 is fixed to the vertical plate part through bolts to ensure good heat conduction between the heat sink 11 and the side of the battery unit.

[0065] When the upper folding part and the lower folding part are installed, the upper folding part is located above the top cooling plate 3, and the lower folding part is located below the bottom cooling plate 4. This design enables the mounting frame 5 to tightly wrap the battery unit and the cooling plate, enhancing the structural stability of the entire heat dissipation device. The upper folding part and the lower folding part can be fixed to the vertical plate part by means of welding, riveting or bolt connection.

[0066] The mounting frame 5 with such a structure first enhances the overall structural stability of the heat dissipation device, makes the connection between each component closer, and reduces the problem of heat dissipation performance degradation caused by component loosening. Secondly, the mounting frame 5 protects the battery unit and the cooling plate, reducing the risk of damage caused by external factors. In addition, by arranging the heat sink 11 on the vertical plate part, the space is fully utilized, making the overall structure more compact.

[0067] As Figure 1 、 Figure 3 shown, in this embodiment, the protective cover 8 and the water pump 14 are both arranged on the vertical plate part of the mounting frame 5 located on the right side of the battery unit, so that the space on the side of the vertical plate part can be fully utilized to arrange the water inlet pipe 6, the water outlet pipe 7, the water extraction pipe 9 and the water supply pipe 10, making the structural design more compact and the space utilization more reasonable.

[0068] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
