[0031] like Figure 2and Figure 5 As shown in the embodiment, the cooling mechanism 400 comprises:

[0032] The fixed box 410 is fixedly connected to one end of the box body 200, the collecting box 420 is fixedly sleeved in the fixed box 410, one end of the air inlet pipe 110 penetrates through one side of the fixed box 410 and is fixedly connected to one side of the collecting box 420, the inside of the air inlet pipe 110 is in communication with the inside of the collecting box 420, one end of each of the plurality of coil pipes 430 is fixedly connected to the other side of the collecting box 420, the inside of each of the plurality of coil pipes 430 is in communication with the inside of the collecting box 420, the other end of each of the plurality of coil pipes 430 is fixedly connected to the other side of the fixed box 410, a plurality of air inlet holes are formed in the other side of the fixed box 410, each of the plurality of air inlet holes corresponds to one of the plurality of coil pipes 430, the inside of each of the plurality of coil pipes 430 is in communication with the inside of the corresponding air inlet hole, the water pump box 440 is arranged on the top of the fixed box 410, a water pump is arranged in the inside of the water pump box 440, the water outlet of the water pump is fixedly connected to the top surface of the fixed box 410 through a conduit, and the bottom surface of the fixed box 410 and the water inlet of the water pump are both fixedly connected to the water guide pipe 401, one end of each of the two water guide pipes 401 penetrates through the top surface of the cover plate 220 and the bottom surface of the box body 200, and one end of each of the two water guide pipes 401 is fixedly connected to the top and bottom of the connecting box 320, the inside of the connecting box 320, the two water guide pipes 401 and the fixed box 410 are in communication, the bottom of each of the U-shaped pipes 310 is provided with the partition plate 321, each of the partition plates 321 is fixedly sleeved in the inside of the connecting box 320, the top surface of each of the partition plates 321 is provided with the through hole, the inside of each of the through holes is fixedly connected to the hose, and one end of each of the hoses is fixedly connected to one end of the U-shaped pipe 310 above the adjacent partition plate 321.

[0033] In implementation, the body 100 can draw air inside the cooling mechanism 400 through the air inlet pipe 110, because the air inside the box 200 can be heated due to heat exchange with the body 100. The water pump is started to draw water from the top of the connecting box 320 into the fixed box 410, so that the fixed box 410 is filled with water with a lower temperature. Then the body 100 can draw external air through the air inlet pipe 110, the collection box 420 and the multiple coils 430. When the external air passes through the coils 430, it can exchange heat with the water inside the fixed box 410 to reduce the temperature. Then the air enters the body 100 through the collection box 420 and the air inlet pipe 110, thereby reducing the temperature of the air entering the body 100, which helps to reduce the generation of heat and improve the cooling effect. The water drawn by the water pump from the top of the connecting box 320 flows back into the connecting box 320 from the bottom end of the connecting box 320 through the water guide pipe 401 at the bottom of the fixed box 410. Then, due to the multiple partitions 321 inside the connecting box 320, the water flowing back into the connecting box 320 flows through the hoses on the partitions 321 and the U-shaped pipes 310 on the partitions 321 in turn. After the water flows into one end of the adjacent U-shaped pipe 310 through the hose on the partition 321, it flows through the adjacent U-shaped pipe 310 and reflows into the connecting box 320 from the other end of the adjacent U-shaped pipe 310. Then the water flows into the U-shaped pipe 310 above through the partition 321 above the adjacent U-shaped pipe 310, thereby circulating the water inside the multiple U-shaped pipes 310 and the fixed box 410 and contacting the low-temperature items inside the placing box 340 to keep the overall water temperature low.

[0034] Example Two

[0035] On the basis of example one, the square duct 361 is arranged to prevent external air from entering the box 200 from the exhaust fan 360.

[0036] As shown in Figure 1 and Figure 2 In this embodiment, the box 200 is fixedly connected with multiple square ducts 361 on one side, and the multiple square ducts 361 correspond one-to-one with the multiple exhaust fans 360. The multiple exhaust fans 360 are located inside the corresponding square ducts 361.

[0037] In implementation, the square duct 361 is used to form an air duct to continuously exhaust the air drawn from the box 200 by the exhaust fan 360, so that external air is not easy to enter the box 200 from the exhaust fan 360.
