[0055] In one embodiment, the to-be-cooled component 12 is a battery cell. Specifically, the temperature of the battery cell is likely to rise during operation, and needs to be cooled in time.

[0056] Please continue reading Figure 1 The liquid cooling assembly 20 includes an organ pipe 21, an inlet pipe 22 and an outlet pipe 23. The organ pipe 21 is a hollow structure.

Specifically, the first liquid cooling chamber 13 is connected to the inlet pipe 22, and the second liquid cooling chamber 14 is connected to the outlet pipe 23. At this time, the liquid enters the inlet pipe 22 through the first liquid cooling chamber 13, flows into the organ pipe 21, then flows into the outlet pipe 23, and finally flows into the second liquid cooling chamber 14, completing a cycle. The organ pipe 21 is reused as a liquid flow channel to achieve a compact structure and a better cooling effect.

[0057] See also Fig.10 The box 10 includes a fourth liquid cooling chamber 182, which is in communication with the second liquid cooling chamber 14. The fourth liquid cooling chamber 182 is in communication with the box suction module 19. The box pumping device 42 and the box drying device 43 are both located in the box suction module 19 and are in communication with the fourth liquid cooling chamber 182. Specifically, the fourth connecting side plate 164 and the outer box 15 are arranged to form the fourth liquid cooling chamber 182. The cooling liquid enters the fourth liquid cooling chamber 182 through the second liquid cooling chamber 14. The box suction module 19 includes the box pumping device 42 and the box drying device 43. At the same time, the fourth liquid cooling chamber 182 is connected to the box suction module 19, so that the box pumping device 42 can extract the cooling liquid in the fourth liquid cooling chamber 182, and the box drying device 43 can dry the fourth liquid cooling chamber 182.

[0058] See also Fig.10 The box suction modules 19 between adjacent boxes 10 are connected by pipes 192. At the same time, the box suction module 19 located at the bottom box 10 is provided with a drain port, so that the cooling liquid in each layer of the box 10 is discharged through the drain port at the bottom layer, thereby realizing the circulation of the cooling liquid.

[0059] See also Fig.11A third reinforcing rib 183 is provided in the fourth liquid cooling chamber 182. One end of the third reinforcing rib 183 is gradually inclined downward from the end of the first liquid cooling chamber 13 to the middle of the fourth liquid cooling chamber 182, and the other end is gradually inclined downward from the second liquid cooling chamber 14 to the middle of the fourth liquid cooling chamber 182. Adjacent third reinforcing ribs 183 are connected. Specifically, the third reinforcing ribs 183 are inclined, and the middle of the third reinforcing ribs 183 has a through hole 193, which is convenient for the cooling liquid to flow through. The liquid flows downward along the through hole 193 under the action of gravity, flows through the connecting port 191 to the box body pumping device 42, and then the cooling liquid is pumped to the bottom of the box body 10 through the box body pumping device 42, and finally discharged through the drain port.
