Specifically, the battery is located in the receiving space of the frame 102, and then the box cover 2 is closed. At this time, the box cover 2 and the liquid cooling plate 101 are located above and below the battery. The battery generates heat during operation. The driving system allows the coolant to be transported from the first connecting pipe 6 to the first flow channel 3. The coolant in the first flow channel 3 is then transported from the second connecting pipe 7 to the second flow channel 5. The coolant in the second flow channel 5 flows back to the cooling box 4 from the third connecting pipe 8. After the heat generated by the battery is transferred to the body 1 and the box cover 2, the heat is absorbed by the coolant to achieve heat dissipation of the battery. At the same time, the air pump 9 is started, so that the air in the body 1 is transported from the air inlet pipe 10 to the air pump 9, so that the heat generated by the battery is discharged. Subsequently, the air in the air pump 9 flows back to the body 1 from the air outlet pipe 11. When the air flows in the air outlet pipe 11, the heat in the air in the air outlet pipe 11 is transferred to the coolant in the cooling box 4, so that the heat dissipation of the air is realized, that is, the air after the heat dissipation flows back to the body 1 from the air outlet pipe 11. Here, through the flow of air in the body 1, it is convenient to discharge the heat generated at various positions of the battery at the same time, that is, the uniformity of the heat dissipation of the battery is improved, and the service life of the battery is extended; The air outlet pipe 11 includes a first pipe section 111 and a second pipe section 112.

The connection between the air inlet pipe 10 and the body 1 is located between the two ends of the second pipe section 112, and the two ends of the second pipe section 112 are distributed on the left and right. The body 1 is provided with a rotating rod 12, the rotating rod 12 is hollow, one side of the rotating rod 12 is connected with a rotating tube 13, one end of the rotating tube 13 is inserted into the air intake pipe 10, the other end of the rotating tube 13 is communicated with the cavity in the rotating rod 12, the rotating tube 13 is parallel to the front-to-back direction, the rotating tube 13 is rotatable and sealedly connected with the air intake pipe 10, a plurality of through holes 14 are provided on the front side of the rotating rod 12, the plurality of through holes 14 are distributed along the diameter direction of the rotating tube 13, a rotating device is provided in the air intake pipe 10, the rotating device uses the flow of air in the air intake pipe 10 as a driving force to realize the self-rotation of the rotating tube 13; The rotating device includes a fan blade 15 and a rotating shaft 16, wherein the rotating shaft 16 is coaxially arranged with the rotating tube 13, one end of the rotating shaft 16 is fixedly connected with the rotating rod 12, the fan blade 15 is mounted on the other end of the rotating shaft 16, and the rotating shaft 16 is rotatably connected with the intake pipe 10 via a bearing 17; When the air flows in the air intake pipe 10, the fan blades 15 are driven to rotate. The rotation of the fan blades 15 drives the rotating shaft 16 to rotate on the bearing 17. The rotation of the rotating shaft 16 drives the rotating rod 12 and the rotating tube 13 to rotate synchronously. When the air in the body 1 is transported to the air intake pipe 10, it is first transported from the through hole 14 to the cavity of the rotating rod 12, and then transported from the rotating tube 13 to the air intake pipe 10. Through the rotation of the rotating rod 12, the flow direction of the exhaust air in the body 1 is always in a changing rotation. Compared with the air with a fixed flow direction, it is easier to discharge the heat concentrated in the corners, that is, the air has a better effect of taking away the heat from the battery, thereby further improving the heat dissipation effect of the battery; Two clamping plates 18 and two guide rods 19 are arranged in the body 1. The two clamping plates 18 are respectively located on the left and right sides of the air intake pipe 10. The two clamping plates 18 are both located between the two ends of the second pipe section 112. The two guide rods 19 are distributed front and back. The guide rods 19 are parallel to the left and right directions. The clamping plates 18 are movably sleeved on the two guide rods 19. Two locking nuts are arranged on the guide rods 19. The two locking nuts on the same guide rod 19 correspond to the two clamping plates 18 one by one. The two clamping plates 18 are both located between the two locking nuts on the same guide rod 19. The cavity in the body 1 is divided into an installation cavity and an air cavity by the two clamping plates 18. When installing a battery, the battery is placed between the two clamping plates 18, that is, the battery is installed in the installation cavity, and the battery is simultaneously located between the two guide rods 19. Subsequently, the locking nut is rotated so that the locking nut pushes the two clamping plates 18 to move closer, so that the two clamping plates 18 clamp and fix the battery. A plurality of ridges 20 are provided at the bottom of the body 1, and the plurality of ridges 20 are spaced from front to back. The top of the clamping plate 18 is in the same horizontal plane as the top of the body 1, and the top of the clamping plate 18 is sealed to the bottom of the box cover 2. The front and rear sides of the clamping plate 18 are respectively sealed to the front and rear sides of the body 1, and the bottom of the clamping plate 18 is sealed to the top of the ridges 20. A moving strip 21 is provided between two adjacent ridges 20, and the moving strip 21 is fixedly provided at the bottom of the clamping plate 18. A gap is provided between the moving strip 21 and the bottom of the body 1, and the moving strip 21 is parallel to the left and right directions. A groove 22 is provided at the top of the moving strip 21, and each groove The grooves 22 are all located between the two clamping plates 18, and the grooves 22 extend to one end of the moving strips 21. A gap is set between two moving strips 21 adjacent to each other in the left and right directions. When air is transported from the air outlet pipe 11 to the body 1, the air first enters the air cavity, and the air in the air cavity can only flow in from between two adjacent convex strips 20. When the air between the two adjacent convex strips 20 is transported to between two moving strips 21 adjacent to each other in the left and right directions, the air then flows upward from the gap between two moving strips 21 adjacent to each other in the left and right directions. In fact, after the battery is installed, the bottom of the battery fits with the top of the convex strip 20, and the air at the bottom of the battery can flow through the grooves 22, so that the heat at the bottom of the battery is discharged along with the air, thereby improving the heat dissipation effect. A pressing plate 23 is provided on one side of the clamping plate 18 close to the air inlet pipe 10, and the pressing plate 23 is connected to the clamping plate 18 via an elastic member; An elastic plate 24 is provided at the bottom of the box cover 2, and the elastic plate 24 is located between the two extrusion plates 23; The elastic plate 24 and the convex strip 20 are both made of elastic flame-retardant rubber; When installing the battery, the battery is placed on the convex strip 20 and between the two extrusion plates 23. When the two clamping plates 18 move close to each other, the extrusion plates 23 are driven to move synchronously. When the extrusion plates 23 abut against the battery, as the clamping plates 18 continue to move, the distance between the clamping plates 18 and the extrusion plates 23 is reduced. At this time, the elastic force generated by the elastic member causes the two extrusion plates 23 to generate a clamping force on the battery, that is, the battery is clamped and fixed. When the box cover 2 is closed, the battery is clamped and fixed in the up and down directions by the convex strip 20 and the elastic plate 24. Among them, the forward direction of the new energy vehicle is parallel to the guide rod 19. When the new energy vehicle collides or emergency brakes, the elastic member buffers the battery. When the new energy vehicle is bumped during the process, the elastic plate 24 and the convex strip 20 made of elastic flame-retardant rubber material are used to buffer, thereby protecting the battery and extending the battery life. The elastic member is provided in plurality, and the plurality of elastic members are distributed along the front-to-back direction; The elastic member includes a moving rod 25 and a spring 26. The moving rod 25 is affected by the guide rod 19. The moving rod 25 passes through the clamping plate 18. The moving rod 25 and the clamping plate 18 are slidably and sealedly connected. The spring 26 is sleeved on the moving rod 25. The spring 26 is located between the extrusion plate 23 and the clamping plate 18. The two ends of the spring 26 are respectively connected to the extrusion plate 23 and the clamping plate 18. During the process of fixing the battery, the distance between the extrusion plate 23 and the clamping plate 18 is reduced, that is, relative movement occurs between the moving rod 25 and the clamping plate 18, and the spring 26 is deformed. The elastic clamping of the battery is achieved through the elastic force of the spring 26. Here, it should be noted that a threading port is provided on the extrusion plate 23, and the wires on the battery pass through the threading port and the outlet port in sequence, and the outlet port and the threading port are sealed by a sealing member, and the sealing member can be a sealant; The main body 1 is provided with a plurality of tube bodies 27, and the plurality of tube bodies 27 correspond to the plurality of moving rods 25 one by one. The tube bodies 27 and the moving rods 25 are coaxially arranged, and the tube bodies 27 are fixedly penetrated on the main body 1. One end of the moving rod 25 away from the clamping plate 18 is inserted into one end of the tube body 27, and the moving rod 25 is slidably and sealedly connected with the tube body 27; When the battery is displaced in the left and right directions, the extrusion plate 23 moves synchronously, that is, the moving rod 25 and the tube body 27 move relative to each other, so that the air in the tube body 27 flows with the air outside the body 1. The tube body 27 can absorb the heat generated by the battery in the body 1, and the heat dissipation effect is further improved through the flow of air in the tube body 27. To sum up, while liquid cooling is achieved for the battery, heat dissipation for the battery is also achieved through the flow of air, so that the heat generated at various positions of the battery can be discharged at the same time, that is, the uniformity of battery heat dissipation is improved and the battery service life is extended. Secondly, by rotating the rotating rod 12, the flow direction of the exhaust air in the main body 1 is always in a changing rotation, which is convenient for discharging the heat concentrated in the corners, that is, the air can better take away the heat from the battery, thereby further improving the heat dissipation effect of the battery. In addition, the spring 26 and the elastic plate 24 and the convex strip 20 made of elastic flame-retardant rubber material can achieve buffering of the battery, thereby protecting the battery.
