The ventilation slots 7 further improve the heat dissipation effect.
[0025] Reference Figure 2An electromagnetic cavity 13 is provided inside the reversing valve body 1, and an electromagnet 12 is fixedly connected inside the electromagnetic cavity 13. The electromagnet 12 is electrically connected to the battery 3. A compression spring 14 is fixedly connected to the inner side of the electromagnetic cavity 13. The other end of the compression spring 14 is fixedly connected to one side of an iron block 15. The iron block 15 is slidably connected inside the electromagnetic cavity 13, and a movable valve core 16 is fixedly connected to the other side of the iron block 15.
[0026] The electromagnetic cavity 13 is used to install the reversing valve driving device. When the electromagnet 12 is powered on, it magnetically attracts the iron block 15, thereby driving the movable valve core 16 to move, and the compression spring 14 plays a buffering role.
[0027] Reference Figure 2 The movable valve core 16 is slidably connected to the inside of the flow control channel 22, and the flow control channel 22 is opened in the inside of the reversing valve body 1. The outside of the movable valve core 16 is fixedly connected with a sealing block 17. The other end of the movable valve core 16 is arranged in the inside of the valve core limiting groove 18. The top of the reversing valve body 1 is fixedly connected with a first liquid outlet pipe 20, and the bottom end of the first liquid outlet pipe 20 is fixedly connected to the inside of the flow control channel 22.

[0029] Working principle: When the electromagnetic reversing valve is used, the iron block 15 is magnetically attracted by controlling the power supply between the electromagnet 12 and the battery 3, thereby driving the movable valve core 16 to slide inside the valve core limit groove 18, thereby driving the sealing block 17 to slide and adjust the position. Since the flow control channel 22 is connected with the liquid inlet pipe 19 and the two groups of liquid outlet pipes, the movable valve core 16 is moved, and the movable valve core 16 drives the two groups of sealing blocks 17 to move. At this time, the left sealing block 17 closes the second liquid outlet pipe 21, and the right sealing block 17 is separated from the closure of the first liquid outlet pipe 20, thereby completing the electromagnetic reversal. The heat generated by the battery 3 during operation is transferred to the support frame 4 and to the heat sink 5, and the heat is dissipated through a plurality of heat dissipating fins 6. The ventilation groove 7 can help dissipate heat. The heat dissipated inside the battery cavity 2 is partially discharged through the heat dissipation holes 8 on the outer cover 10, and most of the heat is discharged through the heat dissipation fan 11, so that the overall heat dissipation effect is good.
