[0029] Reference Figure 1As shown, the utility model provides a technical solution: an efficient cooling battery stack module, comprising a battery stack module body 1, a plurality of battery bodies 2 are installed on the surface of the battery stack module body 1, and a heat dissipation structure 3 is provided on the surface of the battery stack module body 1. By providing the heat dissipation structure 3, the heat dissipation effect of the battery stack module body 1 is improved by adding heat dissipation fins 306 on the surface of the battery stack module body 1, thereby reducing the situation where the temperature of the battery stack module body 1 is too high. A cleaning structure 4 is provided on the surface of the frame 301, and by providing the cleaning structure 4, it is easy to clean the heat dissipation fins 306, thereby avoiding dust from adhering to the surface of the heat dissipation fins 306, thereby ensuring the heat dissipation effect of the heat dissipation fins 306 and improving the effect of the battery stack module body 1.

[0030] The specific settings and functions of the heat dissipation structure 3 and the cleaning structure 4 are described in detail below.

[0031] Reference Figure 2 and Figure 3 and Figure 4 As shown, in this embodiment: the heat dissipation structure 3 includes a frame 301, one end of the battery stack module body 1 is located in the frame 301, both sides of the frame 301 are threadedly connected with threaded rods 302, and the ends of the two threaded rods 302 close to each other are rotatably connected with a pressure plate 303, and the surface of the frame 301 is fixedly connected with a plurality of heat conducting plates 304, and one side of the plurality of heat conducting plates 304 is fixedly connected with a rectangular plate 305, and the side of the rectangular plate 305 away from the heat conducting plate 304 is fixedly connected with a plurality of heat dissipation fins 306. Rectangular grooves 307 are provided on both sides of the heat conducting plate 304, and a plurality of springs 308 are fixedly connected to the inner wall of the rectangular groove 307, and a copper sheet 309 is fixedly connected to the side of the spring 308 away from the heat conducting plate 304, and the copper sheet 309 will be attached to the surface of the battery body 2 with the help of the elastic force of the spring 308, and the copper sheet 309 is attached to the surface of the battery body 2, thereby further improving the heat dissipation effect of the large battery body 2. A plurality of grooves 310 are provided on the side of the copper sheet 309 away from the heat conducting plate 304. The size of the grooves 310 matches the size of the battery body 2. The battery body 2 will be inserted into the grooves 310. The grooves 310 can increase the fitting area between the copper sheet 309 and the battery body 2, thereby increasing the effect of the copper sheet 309 conducting the heat energy of the battery body 2. A turntable 311 is fixedly connected to one end of the threaded rod 302 away from the pressing plate 303. The vertical section of the turntable 311 is in the shape of a "cross". The rotation of the turntable 311 will drive the threaded rod 302 to rotate. The turntable 311 can facilitate the rotation of the threaded rod 302.

[0032] Reference Figure 5As shown, specifically, the cleaning structure 4 includes two round rods 41, both of which slide through the surface of the frame 301, and one end of each of the two round rods 41 is fixedly connected to a driving arm 42, and the side of the two driving arms 42 close to each other is fixedly connected to a cleaning plate 43, and the surface of the cleaning plate 43 is fixedly connected to a plurality of bristles 44. The surface of the round rod 41 is sleeved with a spring 45, and the two ends of the spring 45 are respectively fixedly connected to the driving arm 42 and the frame 301. The round rod 41 will drive the driving arm 42 to reset with the help of the stretching force of the spring 45, and the spring 45 reaches a position that is convenient for resetting the cleaning plate 43, and then it is convenient to limit the position of the cleaning plate 43. A protective pad 46 is fixedly connected to one side of the driving arm 42, and the protective pad 46 is made of rubber. After the driving arm 42 moves to a suitable position, it will drive the protective pad 46 to collide with the frame 301, and the protective pad 46 can prevent the spring 45 from driving the driving arm 42 to reset due to excessive impact force and damage.

[0033] Working principle: when the battery stack module body 1 needs to be cooled, the frame 301 is first put on one side of the battery stack module body 1. The frame 301 will drive several heat conducting plates 304 to be inserted into the battery stack module body 1. When the heat conducting plates 304 are inserted into the battery stack module body 1, they will be in the gaps between several battery bodies 2. When the heat conducting plates 304 are fully inserted into the battery stack module body 1, the copper sheet 309 will fit on the surface of the battery body 2 with the help of the elastic force of the spring sheet 308, and the battery body 2 will be stuck in the groove 310. Then, the turntable 311 is rotated, and the rotation of the turntable 311 will drive the threaded rod 302 to rotate. The rotation of the threaded rod 302 will move inside the frame 301 with the help of the thread. The movement of the threaded rod 302 will drive the pressure plate 303 to move toward the direction close to the battery stack module body 1. When the pressure plate 303 moves to a suitable position, it will fit tightly against the surface of the battery stack module body 1, thereby limiting the frame 301 to the surface of the battery stack module body 1. At this time, when the battery stack module body 1 generates heat, the heat will be conducted to the copper sheet 309 through the battery body 2, and then conducted to the heat conducting plate 304 through the spring 308. The heat conducting plate 304 will conduct the heat to the heat dissipating fin 306 through the rectangular plate 305, and then dissipate into the air.

[0034] When it is necessary to clean the heat dissipation fins 306, first pull the round rod 41. The movement of the round rod 41 will move inside the frame 301. The movement of the round rod 41 will drive the driving arm 42 to move. The movement of the driving arm 42 will compress the spring 45. The movement of the driving arm 42 will drive the cleaning plate 43 to move. The movement of the cleaning plate 43 will drive the bristles 44 to slide along the surface of the heat dissipation fins 306, thereby brushing off the dust on the surface of the heat dissipation fins 306. After cleaning the heat dissipation fins 306, release the round rod 41. The round rod 41 will use the extension force of the spring 45 to drive the driving arm 42 to reset, and then drive the cleaning plate 43 to reset. When resetting, the driving arm 42 will drive the protective pad 46 to move towards the direction close to the frame 301. When the driving arm 42 moves to a suitable position, it will drive the protective pad 46 to collide with the frame 301. The protective pad 46 can prevent damage caused by excessive impact force when the spring 45 drives the driving arm 42 to reset.
