DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Reference Figure 1 , provides an energy storage device that is easy to cool and dissipate heat, which includes: a box body 100, and a heat dissipation part 200. The interior of the box body 100 is hollow, so that the inner wall of the box body 100 can form a storage cavity for placing the energy storage battery pack 300. The heat dissipation part 200 is arranged in the storage cavity. An air inlet 211 and an air outlet 212 are provided on the heat dissipation part 200, wherein the air inlet 211 is arranged through the outer wall of the box body 100 so that the air inlet 211 can be connected to the outside world, and the air outlet 212 is arranged toward the energy storage battery pack 300 in the storage cavity, so that the outside air can be guided to the energy storage battery pack 300 through the heat dissipation part 200, so that the air contacts the energy storage battery pack 300, thereby cooling the energy storage battery pack 300 inside the energy storage device. In addition, a heat dissipation port 131 is provided on the box body 100, wherein the air inlet 211, the air outlet 212 and the heat dissipation port 131 are sequentially connected, so that the air that has cooled the energy storage battery pack 300 can be discharged through the heat dissipation port 131, and the heat in the accommodating cavity is promptly discharged to the outside for heat dissipation, thereby improving the cooling and heat dissipation effect inside the box body 100, avoiding the occurrence of local overheating, and ensuring the service life of the energy storage device.

[0041] Furthermore, the heat dissipation port 131 may be provided on the side wall, bottom wall or top wall of the box body 100. If the heat dissipation port 131 is provided opposite to the air outlet 212 of the heat dissipation portion 200, so that the energy storage battery pack 300 can be located between the air outlet 212 and the heat dissipation port 131, it is more conducive to heat dissipation and can improve the heat dissipation effect.

[0042] Furthermore, the box body 100 may be cylindrical or rectangular. Comparatively speaking, the cylindrical box body 100 is easier to set the energy storage battery pack 300 .

[0043] Furthermore, a plurality of supporting legs 140 are evenly and fixedly disposed on the bottom of the box body 100 , and the box body 100 can be fixedly placed on a plane through the plurality of supporting legs 140 .

[0044] In some specific embodiments of the present invention, the energy storage battery pack 300, the heat dissipation port 131 and the air outlet 212 are at least one, referring to Figure 2 and Figure 3 , 4 energy storage battery packs 300 are arranged in the accommodating cavity of the box body 100, and the 4 energy storage battery packs 300 are evenly arranged around the axis of the box body 100, so as to increase the capacity of the energy storage device. Correspondingly, the heat dissipation part 200 is arranged in the middle of the box body 100 along the axis of the box body 100, and 4 air outlets 212 are evenly opened on the outer wall of the heat dissipation part 200. The 4 air outlets 212 and the 4 energy storage battery packs 300 are arranged one by one, and each air outlet 212 faces the energy storage battery pack 300 corresponding to it. Four heat dissipation ports 131 are evenly arranged on the side wall of the box 100, and the four heat dissipation ports 131 are arranged opposite to the four air outlets 212, so that each energy storage battery pack 300 can be located between one of the heat dissipation ports 131 and the air outlet 212, and the four energy storage battery packs 300 can be cooled down at the same time while ensuring the energy storage capacity, avoiding the occurrence of local overheating and improving the heat dissipation performance. Among them, the length of the air outlet 212 and the heat dissipation port 131 are both greater than or equal to the length of the energy storage battery pack 300, so as to ensure that the entire energy storage battery pack 300 can be evenly cooled down.

[0045] It should be noted that the number of energy storage battery packs 300, heat dissipation ports 131 and air outlets 212 is determined according to the size of the energy storage device. If the energy storage device is larger, more energy storage battery packs 300 can be arranged inside, and accordingly, more heat dissipation ports 131 and air outlets 212 can be opened.

[0046] In some specific embodiments of the present invention, refer to Figure 2The heat dissipation part 200 includes: a tube body 210 and an air induction mechanism 220. The tube body 210 is arranged in the middle of the accommodating cavity along the axis of the box body 100, and both ends of the tube body 210 extend along the axis of the box body 100. One end of the tube body 210 is passed through the middle of the top wall of the box body 100, and the other end of the tube body 210 is passed through the middle of the bottom wall of the box body 100, so that two air inlets 211 are formed through the two ends of the tube body 210, so that the outside air can flow into the tube body 210 through the two air inlets 211. The air outlet 212 is opened on the side wall of the tube body 210 close to the energy storage battery pack 300, so that the air outlet 212 can be arranged toward the energy storage battery pack 300. The air induction mechanism 220 is arranged in the tube body 210, and the working ends of the air induction mechanism 220 extend along the axis of the tube body 210 to the two ends of the tube body 210 respectively, so that the outside air can be quickly introduced into the air inlet 211 through the air induction mechanism 220, thereby accelerating the air flow rate, so that the air can quickly flow to the air outlet 212 to cool the energy storage battery pack 300.

[0047] It should be noted that the setting position of the tube body 210 in the box body 100 is determined by the setting position of the energy storage battery pack 300 in the box body 100. The tube body 210 is vertically set along the axis of the box body 100 so that the tube body 210 can be located exactly between the multiple energy storage battery packs 300, so that the multiple air outlets 212 can guide the air to the multiple energy storage battery packs 300 respectively and simultaneously. If the setting positions of the multiple energy storage battery packs 300 are changed, the setting position of the tube body 210 can also be changed accordingly.

[0048] In some specific embodiments of the present invention, refer to Figure 2 The air induction mechanism 220 includes: a dual-axis motor 221 and a fan blade 222. The dual-axis motor 221 is arranged in the middle of the tube body 210, and the two output ends of the dual-axis motor 221 extend to the two ends of the tube body 210 respectively along the body length direction of the tube body 210. There are at least two fan blades 222, and the two fan blades 222 are respectively arranged at the two output ends of the dual-axis motor 221, so that the fan blades 222 can be arranged at a position close to the air inlet 211. When the energy storage battery pack 300 needs to be cooled, by starting the dual-axis motor 221, the two fan blades 222 can be driven to rotate at the same time. Under the rotation of the fan blades 222, the outside air can be sucked into the tube body 210 from the air inlet 211.

[0049] In some specific embodiments of the present invention, refer to Figure 2 and Figure 3The heat dissipation unit 200 further includes: a first air guide mechanism 230 and a second air guide mechanism 240. The first air guide mechanism 230 is disposed in the tube body 210, and is used to guide the air introduced into the tube body 210 to the air outlet 212. The second air guide mechanism 240 is disposed on the outer wall of the air outlet 212, and the second air guide mechanism 240 is also disposed on both sides of the energy storage battery pack 300 corresponding to the air outlet 212, so that the air can be driven to accurately contact the energy storage battery pack 300, thereby ensuring the cooling efficiency.

[0050] It should be noted that there is at least one second air guiding mechanism 240, and the number of second air guiding mechanisms 240 is determined by the number of air outlets 212. One second air guiding mechanism 240 is provided at each air outlet 212.

[0051] Further, refer to Figure 2 The first air guide mechanism 230 includes: a first air guide plate 231 and a second air guide plate 232. The first air guide plate 231 and the second air guide plate 232 are at least two groups, wherein the two groups of first air guide plates 231 are symmetrically arranged in the tube body 210, the two groups of second air guide plates 232 are arranged between the two groups of first air guide plates 231, and the two groups of second air guide plates 232 are also symmetrically arranged. The first air guide plate 231 and the second air guide plate 232 are both inclined structures biased toward the air outlet 212, and the inclination angle of the second air guide plate 232 is greater than the inclination angle of the first air guide plate 231, so that the air introduced into the tube body 210 can be more smoothly guided to the air outlet 212, ensuring smooth air discharge from the air outlet 212.

[0052] Further, refer to Figure 3 , the second air guide mechanism 240 includes: a third air guide plate 241 and a fourth air guide plate 242. The third air guide plate 241 and the fourth air guide plate 242 are at least two groups. Among them, the two groups of third air guide plates 241 are symmetrically arranged on the outer wall of the air outlet 212, so that the two groups of third air guide plates 241 can be respectively located on both sides of the energy storage battery group 300 corresponding to the air outlet 212. In addition, the third air guide plate 241 is an arc-shaped structure, so that the contact area between the air flowing out of the air outlet 212 and the energy storage battery group 300 can be expanded, and the air flow time can also be extended. The fourth air guide plate 242 is symmetrically arranged on the opposite sides of the two groups of third air guide plates 241, and the fourth air guide plate 242 is biased towards the energy storage battery group 300, so as to further increase the contact area between the air and the energy storage battery group 300.

[0053] In some specific embodiments of the present invention, refer to Figure 1 and Figure 2, an air guide cover 120 is provided at the air inlet 211. There are two air guide covers 120, one of which is arranged above the middle of the top wall of the box body 100, and the other air guide cover 120 is arranged below the middle of the bottom wall of the box body 100, and the two air guide covers 120 are respectively connected to the two air inlets 211 of the tube body 210, so as to facilitate the inflow of air.

[0054] Further, refer to Figure 1 The two air guide covers 120 are respectively covered with a first dustproof net 121 on the side facing away from the box body 100. Each heat dissipation port 131 is also covered with a second dustproof net 131. The first dustproof net 121 and the second dustproof net 131 are provided to prevent dust from flowing into the box body 100 when the energy storage battery pack 300 is cooled.

[0055] In some specific embodiments of the present invention, refer to Figure 1 , Figure 2 and Figure 3 A temperature detection control component 110 is also provided on the box body 100. The temperature detection control component 110 is connected to the dual-axis motor 221. The temperature detection control component 110 can detect the real-time temperature in the accommodating cavity. When the temperature in the accommodating cavity is too high, the temperature detection control component 110 can directly control the operation of the dual-axis motor 221, thereby cooling the energy storage battery pack 300.

[0056] Further, the temperature detection control component 110 includes: a main controller 111 and a plurality of temperature sensors 112. The main controller 111 is disposed on the top of the box 100. The plurality of temperature sensors 112 are evenly disposed on the top of the accommodating cavity of the box 100 around the axis of the box 100, and are fixed on the inner wall of the box 100. The main controller 111 is electrically connected to the temperature sensors 112 and the dual-axis motor 221. The temperature inside the box 100 can be monitored from multiple angles through multiple temperature sensors 112. When the internal temperature of the box 100 is too high, the main controller 111 controls the dual-axis motor 221 to work, and the dual-axis motor 221 drives the fan blades 222 at both ends to rotate. The rotation of the fan blades 222 can simultaneously blow air into the tube body 210, so that under the action of the first air guide plate 231, the second air guide plate 232, the third air guide plate 241 and the fourth air guide plate 242, the energy storage battery pack 300 is cooled down, achieving an automatic cooling effect.
