Description

Technical Field

[0001] The invention relates to the field of energy production, and in particular to an energy storage battery pack with a heat dissipation component. Background Art

[0002] As the global demand for clean energy continues to increase, energy storage batteries, as an important supporting equipment for renewable energy, continue to grow in market demand. An energy storage battery pack is an integrated device that combines multiple energy storage battery cells in a certain way and is equipped with corresponding management systems, shells and other components. It can store electrical energy in the form of chemical energy for release when needed. When local overheating occurs inside the battery, it may trigger a series of chain reactions, such as decomposition of positive and negative electrode materials, combustion of electrolytes, etc., ultimately leading to battery fire or even explosion. Therefore, it is necessary to design an energy storage battery pack with a heat dissipation component to quickly take away the heat generated by the battery and maintain the uniformity of the battery temperature.

[0003] Existing energy storage battery packs mainly dissipate heat in two ways: liquid cooling and air cooling. In high-power charging and discharging scenarios, the liquid cooling system can quickly take away a large amount of heat and keep the battery temperature safe. Existing liquid cooling usually requires cooling tubes to pass through the battery pack to improve heat exchange efficiency. However, the battery pack may expand in the middle of the periphery during long-term charging and discharging, exerting squeezing pressure on the surrounding cooling tubes in contact. This squeezing pressure may reduce the inner diameter of the cooling tube, hindering the normal flow of coolant and reducing heat dissipation efficiency. Secondly, traditional multiple battery packs are closely arranged together, resulting in poor heat dissipation between battery packs. The gaps between adjacent battery packs are relatively narrow, and it is difficult for air to flow freely in such a narrow space, thus affecting the heat dissipation effect.

[0004] Therefore, it is necessary to propose an energy storage battery pack with a heat dissipation component to solve the above technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an energy storage battery pack with a heat dissipation assembly, which solves the technical problems that the battery pack may expand and squeeze the cooling tube during long-term charging and discharging, thereby reducing the inner diameter of the cooling tube, hindering the flow of coolant, and reducing the heat dissipation efficiency; and the gaps between battery packs are narrow, making it difficult for air to flow freely, resulting in poor heat dissipation effect.

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 5 As shown, an energy storage battery pack with a heat dissipation component includes a shell 1, at least one battery pack body 11 arranged inside the shell 1 and a heat dissipation plate 12 arranged outside the battery pack body 11, the heat dissipation plate 12 is a concave structure, at least one air inlet fan 13 is arranged on one side of the shell 1, at least one partition 14 is installed on the inner side of the heat dissipation plate 12, the battery pack bodies 11 are fixedly connected to the partition 14, a circulation box 15 is arranged in the shell 1, and a circulating cooling pipe 16 is arranged on the circulation box 15, and the cooling pipe 16 is arranged with a flexible material.

[0020] After the air inlet fan 13 on one side of the housing 1 is started, the external cold air is sucked into the housing 1. The cold air flows in the housing 1 and contacts the heat sink 12. The space between each group of partitions 14 is used to place the battery pack body 11. The partitions 14 are set to heat dissipation materials. The partitions 14 are tightly attached to the bottom of the battery pack body 11. The heat generated by the battery pack body 11 during operation is transferred to the heat sink 12 and the partitions 14 through heat conduction, which is convenient for timely heat dissipation. A pump body for driving the cooling liquid into the cooling pipe 16 is installed inside the circulation box 15, and the pump body can be started by an external controller; like Figure 6-Figure 9 As shown, the anti-pressure component 2 is arranged on the heat sink 12 to prevent the cooling pipe 16 from being squeezed when the battery pack body 11 expands. The anti-pressure component 2 includes a top plate 21, a side plate 22, an ear seat 23, a rotating seat 24 and a micro spring telescopic rod 25. The top plate 21 is arranged above the battery pack body 11. Two side plates 22 are provided, and the two side plates 22 are rotatably connected at the left and right ends of the top plate 21. The top plate 21 and the side plates 22 are shape memory alloys. One end of the cooling pipe 16 passes through the top plate 21 and the side plates 22 and the battery pack body 11. Ear seats 23 are evenly installed on the outer sides of the top plate 21 and the side plates 22, and one side of the ear seat 23 is rotatably connected to the rotating seat 24. A micro spring telescopic rod 25 is hinged on the inner side of the heat sink 12 and on one side corresponding to the rotating seat 24. The moving end of the micro spring telescopic rod 25 is fixedly connected to the rotating seat 24. The top plate 21 and the side plate 22 facing the battery pack body 11 are equipped with an anti-pressure seat 26.

[0021] It should be noted that when the battery pack body 11 does not expand, the top plate 21 and the side plates 22 are located above and on both sides of the battery pack body 11, maintaining a certain gap with the battery pack body 11, and the micro-spring telescopic rod 25 is in a compressed state, providing a certain support force for the top plate 21 and the side plates 22. One end of the cooling pipe 16 passes through the gap between the top plate 21 and the side plates 22 and the battery pack body 11, and performs heat exchange work normally. When the battery pack body 11 expands during a long period of charging and discharging, the surface of the battery pack body 11 will squeeze the top plate 21 and the side plates 22 upward and to the sides. Since the top plate 21 and the side plates 22 are made of shape memory alloys, they have a certain elasticity and deformability. After being squeezed by the battery pack body 11, the top plate 21 and the side plate 22 will bend and deform outward. At the same time, as the top plate 21 and the side plate 22 move outward, the rotating seat 24 on the ear seat 23 will rotate with the movement of the top plate 21 and the side plate 22. At the same time, the micro spring telescopic rod 25 fixedly connected to the rotating seat 24 begins to stretch and releases elastic potential energy. The stretching of the micro spring telescopic rod 25 provides buffering and support for the movement of the top plate 21 and the side plate 22, preventing the top plate 21 and the side plate 22 from excessive deformation, and also protecting the cooling pipe 16 from being squeezed; The bulging degree of each battery pack body 11 may be different, which will drive the rotating seat 24 to rotate on the ear seat 23 to different degrees. The side panels 22 on both sides can rotate at different angles on the top plate 21 to adapt to the different bulging degrees of the battery pack body 11. In this way, it can be ensured that the anti-pressure component 2 can be adaptively adjusted according to the actual expansion of the battery pack body 11, effectively preventing the cooling pipe 16 from being damaged by the bulging of the battery pack body 11; The anti-pressure seat 26 can play a certain buffering role when the battery pack body 11 expands, reduce the direct impact force of the battery pack body 11 on the top plate 21 and the side plate 22, and further protect the cooling pipe 16.

[0022] like Figure 3 , Figure 4 and Fig.10 As shown, the exhaust component 3 is arranged inside the shell 1, and is used to discharge the heat generated by the battery pack body 11 in time. The exhaust component 3 includes a first air inlet duct 31. A support seat 17 fixedly connected to the heat sink 12 is installed on the front side of the inner cavity of the shell 1. The inlet end of the air inlet fan 13 is installed on the front side of the support seat 17 and is fixedly connected to one end of the first air inlet duct 31. The first air inlet duct 31 is away from one end of the air inlet fan 13 and is fixedly connected to the cooling pipe 16. One end of the air inlet fan 13 extends into the top plate 21 and the inner side of the side plate 22 to open a plurality of first air inlet holes 32. An exhaust fan 311 is evenly installed on one side of the top of the shell 1.

[0023] It should be noted that when heat is generated between the battery pack bodies 11, the air intake fan 13 starts to work, and external air flows into the battery pack bodies 11 through the first air inlet pipe 31 and is ejected from the surface of the battery pack bodies 11 through the first air inlet hole 32, so as to dissipate the heat generated by the battery pack bodies 11 in time, and provide a certain flow for the gas gathered between the battery pack bodies 11. The start-up of the exhaust fan 311 can exhaust the gas gathered between the battery pack bodies 11 to a certain extent, thereby improving the heat dissipation effect.

[0024] like Figure 4 and Fig.11 As shown, each battery pack body 11 is arranged in a stepped shape, a second air inlet duct 33 fixedly connected to the first air inlet duct 31 is installed in the middle of the inner cavity of the support seat 17, an air inlet plate 34 is installed at one end of the second air inlet duct 33 away from the first air inlet duct 31, and the opposite sides of the support seat 17 and the air inlet plate 34 are in a stepped structure, and a second air inlet hole 341 arranged in a rectangular shape is opened on one side of the air inlet plate 34 corresponding to each battery pack body 11.

[0025] It should be noted that the air enters the second air inlet duct 33 from the first air inlet duct 31 and then reaches the air inlet plate 34. Since the second air inlet holes 341 on the air inlet plate 34 correspond to each group of battery pack bodies 11, the air can be evenly distributed around each battery pack body 11 through these air inlet holes. For the battery pack bodies 11 arranged in a stepped shape, the air can more effectively contact different parts of each battery pack body 11 according to its layout characteristics, further improving the heat dissipation efficiency. After the air enters around the battery pack body 11 through the second air inlet holes 341, it absorbs the heat emitted by the battery pack body 11, thereby achieving targeted heat dissipation. The air that has absorbed the heat continues to flow under the action of the inlet fan 13 and the exhaust fan 311 and is eventually discharged to the outside of the housing 1 by the exhaust fan 311. At the same time, fresh air from the outside continuously enters through the first air inlet duct 31 and the second air inlet duct 33, forming a continuous air circulation, ensuring that the battery pack body 11 can always obtain effective heat dissipation during operation.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, each battery pack body 11, support seat 17, heat sink 12, air inlet plate 34 and partition 14 are inclined along the exhaust fan 311, which is used to quickly extract the gas inside the shell 1 through the exhaust fan 311, and the shell 1 is provided with an arc-shaped guide plate below the exhaust fan 311.

[0027] It should be noted that the present invention has a tilted layout so that the air inside the housing 1 has a tendency to flow toward the exhaust fan 311 in a natural state. When the exhaust fan 311 is working, the air can flow toward the exhaust fan 311 more smoothly along the tilted surface, thereby improving the flow speed and efficiency of the air, and also further improving the heat dissipation efficiency of the battery pack body 11. The arc-shaped design of the guide plate can guide the air rising from below. After passing through the battery pack body 11 and other components, the air rises along the inclined surface. The guide plate can guide the air more concentratedly toward the exhaust fan 311, ensuring that the air can be smoothly drawn away by the exhaust fan 311, further improving the heat dissipation efficiency.

[0028] like Figure 4 and Fig.11 As shown, the cooling pipe 16 is configured as a plate-like structure, and a notch is opened in the middle thereof. Two first air inlet pipes 31 are provided, and the two first air inlet pipes 31 are fixedly connected in the notch. The cooling pipe 16 is tightly attached to the battery pack body 11, and a certain space is provided between the first air inlet pipe 31 and the battery pack body 11.

[0029] It should be noted that the cooling pipe 16 is configured as a plate-like structure, which increases the contact area with the battery pack body 11, can more efficiently absorb the heat generated by the battery pack body 11, and can cool the gas inside the first air inlet pipe 31; A certain space is provided between the first air inlet pipe 31 and the battery pack body 11, and the space provides a passage for air circulation. When the air inlet fan 13 is working, external air enters the space through the first air inlet pipe 31, and then flows to the battery pack body 11 and the cooling pipe 16. During the air flow in the space, the air can absorb the heat emitted by the battery pack body 11 and the cooling pipe 16, further improving the heat dissipation effect. At the same time, maintaining the space between the first air inlet pipe 31 and the battery pack body 11 can prevent the air inlet pipe from colliding or rubbing with the battery pack body 11 during operation, thereby reducing the risk of damage to the battery pack body 11. like Figure 4 , Fig.10 and Fig.11 As shown, the spraying directions of the second air inlet hole 341 and the first air inlet hole 32 are arranged along the inclined portion of the battery pack body 11 .

[0030] It should be noted that the above design enables the incoming air to flow more directly to various parts of the surface of the battery pack body 11. Since the air flow direction matches the inclination angle of the battery pack body 11, the air can better fit the shape of the battery pack body 11, thereby improving the heat exchange efficiency between the air and the battery pack body 11 and achieving more efficient heat dissipation. At the same time, it can more concentratedly cover the areas of the battery pack body 11 that require heat dissipation. This targeted flow method can reduce air turbulence and energy loss and improve the heat dissipation effect.

[0031] like Fig. 9 , Fig.10 and Fig.12 As shown, one end of the cooling pipe 16 and the first air inlet pipe 31 sequentially extends into each set of top plate 21 and side plate 22, and one end of the cooling pipe 16 and the first air inlet pipe 31 sequentially extends out of each set of top plate 21 and side plate 22 and then extends into the partition 14, both of which have a snake-shaped structure.

[0032] It should be noted that the cooling pipe 16 has a snake-shaped structure inside the top plate 21 and the side plate 22, which greatly increases the contact area between the cooling pipe 16 and the air around the battery pack body 11, and can be more evenly distributed around the battery pack body 11, making the heat dissipation of various parts more uniform. At the same time, the battery pack body 11 installed on one side of the partition 14 can also dissipate heat evenly, reducing the heat transfer generated by the partition 14 between the battery pack body 11.

[0033] The working principle of the present invention is as follows: when the energy storage battery pack with a heat dissipation component is used, when the battery pack body 11 expands during a long period of charge and discharge, the surface of the battery pack body 11 will press the top plate 21 and the side plates 22 upward and to the sides. Since the top plate 21 and the side plates 22 are elastic and deformable, they will bend and deform outward. As the top plate 21 and the side plates 22 move, the rotating seat 24 on the ear seat 23 will rotate, and at the same time, the micro spring telescopic rod 25 fixedly connected to the rotating seat 24 will stretch, releasing elastic potential energy, and the top plate 21 and the side plates 22 will bend and deform outward. The movement of the battery pack body 11 can provide buffering and support to prevent it from excessive deformation, thereby protecting the cooling pipe 16 from being squeezed. The bulging degree of each group of battery pack bodies 11 may be different, which will drive the rotating seat 24 to rotate to different degrees on the ear seat 23. The side panels 22 on both sides can rotate at different angles on the top plate 21 to adapt to the different bulging conditions of the battery pack body 11, so as to realize the adaptive adjustment of the anti-pressure component 2 according to the actual expansion conditions. When the battery pack body 11 generates heat, the air intake fan 13 on one side of the shell 1 is started to suck the external cold air into the shell 1. The air flows through the first air intake duct 31 and the second air intake duct 33, and a part of the air extends from the first air intake hole 32 at one end of the air intake fan 13 into the top plate 21 and the inner side of the side plate 22 to dissipate heat from the surface of the battery pack body 11 and promote the flow of gas gathered between the battery pack bodies 11. Another part of the air reaches the air inlet plate 34 through the second air inlet pipe 33, and is then evenly distributed to the periphery of each battery pack body 11 from the second air inlet holes 341 on the air inlet plate 34 corresponding to each group of battery pack bodies 11. According to the stepped layout characteristics of the battery pack bodies 11, different parts of each battery pack body 11 can be more effectively contacted to achieve targeted heat dissipation. The air inside the outer shell 1 has a tendency to flow toward the exhaust fan 311 in a natural state. When the exhaust fan 311 is working, the air can flow toward the exhaust fan 311 more smoothly along the inclined surface, thereby increasing the air flow speed and efficiency and further improving the heat dissipation efficiency. The arc-shaped guide plate of the outer shell 1 located below the exhaust fan 311 guides the air rising from below, and guides the air more concentratedly toward the exhaust fan 311, ensuring that the air is smoothly drawn away by the exhaust fan 311.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
