[0002] At present, the commonly used way to charge electric vehicles is for riders to go to the shared charging cabinet for electric vehicles and directly replace the rechargeable battery. This method solves the problem of rapid charging of electric vehicles. Since the shared charging cabinet is a closed box, when there are many batteries in the charging state inside, not only the temperature inside the single battery charging compartment will rise, but also the temperature inside the entire shared charging cabinet will rise, and there is a temperature concentration and diffusion effect. Therefore, the heat dissipation of the battery swap cabinet is very important. At present, heat dissipation is carried out by setting fans. Due to the large size of the battery swap cabinet, more fans need to be installed to meet the basic heat dissipation requirements, so that the fans cover a larger area to meet the heat dissipation requirements. The fans need to borrow the energy of the battery swap cabinet to drive, which greatly increases the energy consumption of the battery swap cabinet and does not meet the requirements of low-energy operation of the battery swap cabinet.

When the batteries in the power exchange cabinet 1 are not fully charged, the power exchange cabinet 1 is in low-energy operation and the heat is relatively low, especially at night, when the power exchange cabinet 1 is basically not in operation and the temperature is relatively low at night. During this period of time, a buffer time is provided for the heat sink 4 to reduce the temperature of the heat sink 4, ensuring that the heat can be well absorbed during the day to dissipate the heat of the power exchange cabinet; preferably, when the outside temperature is too high (in summer or high temperature areas), cooling fins are installed on the end face of the heat sink 4 close to the outer wall of the power exchange cabinet 1 to enhance the heat dissipation effect.

[0022] Furthermore, if Figures 1 to 3 As shown, the cooling chamber 3 extends to the top of the power exchange cabinet 1. The top of the power exchange cabinet 1 is connected to a top plate 19 by screws. The top plate 19 is used to close the cooling chamber 3. The top plate 19 adopts a detachable structure of screws, which can open the top of the cooling chamber 3 to facilitate the disassembly and assembly of the heat sink 4. A carrying ring 20 is fixed on the top of the heat sink 4 to facilitate the extraction of the heat sink 4 and installation.

[0023] Furthermore, if Figures 1 to 4As shown, a plurality of abutment blocks 6 are arranged on the side of the heat sink 4 away from the inner wall of the power exchange cabinet 1, and the plurality of abutment blocks 6 are evenly distributed along the height direction of the heat sink 4, and the abutment blocks 6 are slidably connected to the heat sink 4, and the abutment blocks 6 press the heat sink 4 against the inner wall of the cooling chamber 3 by sliding, and a driving chamber 7 is arranged in the heat sink 4, and a slide groove 8 is opened on the side of the heat sink 4 corresponding to the position of the abutment block 6, and the slide groove 8 is connected to the driving chamber 7, and the abutment block 6 is slidably adapted to the slide groove 8, and a lower pressure rod 9 is vertically arranged in the driving chamber 7, and the lower pressure rod 9 is slidably connected to the heat sink 4, and the lower pressure plate 9 moves along the height direction of the heat sink 4, and the lower pressure rod 9 is fixedly sleeved with a lower pressure block 10 at the position corresponding to the abutment block 6. The lower pressing block 10 is located above the corresponding abutting block 6, and a first wedge-shaped surface 11 is provided on the top of the abutting block 6 near one end of the lower pressing block 10. The heat sink 4 is placed in the cooling chamber 3, and then the lower pressing plate 9 is moved downward. The lower pressing plate 9 drives the lower pressing block 10 to move close to the first wedge-shaped surface 11 of the abutting block 6, so that the lower pressing plate 9 squeezes the first wedge-shaped surface 11. Under the guidance of the first wedge-shaped surface 11, the abutting block 6 is extended from the slide groove 8, so that the abutting block 6 is pressed against the side wall of the power exchange cabinet 1, thereby pressing the heat sink 4 against the cooling chamber 3, making the heat sink 4 more stably installed, and there will be no deviation to block the heat dissipation hole 2. At the same time, the installation and disassembly of the heat sink 4 are simple and quick.

[0024] Furthermore, if Figures 1 to 4 As shown, the cross-sectional shape of the lower pressure rod 9 is rectangular, and the inner bottom wall of the driving chamber 7 is provided with a rectangular slide groove 12 along the moving direction of the lower pressure rod 9. The bottom end of the lower pressure rod 9 is slidably adapted in the rectangular slide groove 12, and the top end of the lower pressure rod 9 is rotatably connected with a connecting column 13, and the top of the heat dissipation plate 4 is threaded with a bolt 14, and the tail of the bolt 14 is connected to the connecting column 13. The connecting column 13 is driven to screw downward by tightening the bolt 14, and the rotational freedom of the lower pressure rod 9 is limited by the cooperation of the rectangular slide groove 12 and the lower pressure rod 9, and the connecting column 13 and the lower pressure rod 9 The rotation connection prevents interference between the connecting column 13 and the lower pressure rod 9, so that the lower pressure rod 9 only moves in a straight line, ensuring that the lower pressure block 10 can stably squeeze the abutment block 6 to make it move. At the same time, the bolt 14 can lock the position of the lower pressure rod 9 after being tightened, so as to keep the heat sink 4 in a tight state. When disassembling, it is only necessary to loosen the bolt 14, and the lower pressure rod 9 drives the lower pressure block 10 to move upward and separate from the abutment block 6. At this time, the abutment block 6 can move freely in the slide groove 8, and the heat sink 4 can be taken out by lifting it upward. The operation is simple.

[0025] Furthermore, if Figure 3 and Figure 4As shown, the abutment block 6 is provided with a first wedge-shaped surface 11 at one end thereof connected with a return spring 15, and the end of the return spring 15 away from the abutment block 6 acts on the inner wall of the driving chamber 7. When the return spring 15 is in a normal state, the abutment block 6 is located in the slide groove 8, and a screw rod 16 is slidably penetrated on the abutment block 6, and the return spring 15 is sleeved on the screw rod 16, and a limiting ring 17 is fixed on the screw rod 16.

The abutment block 6 can be installed through the slide groove 8 through the screw rod 16. First, the screw 16 carrying the return spring 15 is passed through the abutment block 6, and then The return spring 15 is connected to the abutment block 6, and then the abutment block 6 is slid into the slide groove 8. The abutment block 6 is limited by the slide groove 8, and the abutment block 6 limits the screw rod 16. The moving screw rod 16 can correspond to the threaded hole 18, and then the screw rod 16 is twisted with a screwdriver to screw the tail end of the screw rod 16 into the threaded hole 18, thereby completing the installation of the abutment block 6. Due to the sliding adaptation of the abutment block 6 and the screw rod 16, the movement of the abutment block 6 is not affected. After the return spring 15 is connected to the abutment block 6, after the lower pressure rod 9 moves up, the abutment block 6 can be reset and moved into the slide groove 8 under the action of the return spring 15. At the same time, under the connection of the reset installation 15, it is ensured that the abutment block 6 will not fall out of the slide groove 8, thereby ensuring the stability of the structure.
