Within the same space, the spiral cooling coil can more fully exchange heat with the item being cooled, thereby accelerating the cooling speed and improving cooling efficiency. The cooling water pump ensures that the cooling medium in the cooling water tank can be continuously transported to the cooling coil through the delivery pipe. The cooling medium circulates within the cooling coil, promptly removing heat from the item being cooled, and then flows back to the cooling water tank through the drain pipe, forming a highly efficient cooling circulation system, further improving cooling efficiency.

[0020] 2. In this utility model, a rotary vane vacuum pump is used as the vacuum pumping device. It boasts high pumping efficiency and excellent vacuum performance, rapidly extracting air from the tank to quickly achieve the required vacuum level.

This effectively prevents the vacuum pump from loosening due to vibration, ensuring its continuous and stable operation. Furthermore, the vacuum suction pipe penetrates the tank, and all components are tightly connected. For example, the connection between the suction pipe and the vacuum pump greatly reduces air leakage, further maintaining the tank's vacuum level and significantly improving the effect and efficiency of vacuum cooling.
