The parts are placed in the closed space of the operation structure, the drying air inlet pipeline 71 and the drying air outlet pipeline 92 are both led into the closed space, and then the drying air with higher pressure can be conveyed to the closed space, so that the parts in the closed space can be dried.

In a specific embodiment, the drying module 3 further includes an air pumping pipeline 38, the drying adapter module 7 further includes an air pumping adapter pipeline 74 for connecting with the air pumping pipeline 38, a vacuum pump 381, a vacuum filter 382 and an air pumping control valve 383 are sequentially disposed on the air pumping pipeline 38 from an end far away from the end connected with the air pumping adapter pipeline 74 to an end connected with the air pumping pipeline 38, a vacuum gauge 741 and an air pumping switch valve 742 are sequentially disposed on the air pumping adapter pipeline 74, and the air pumping adapter pipeline 74 can be introduced into a space where the objects to be dried are located, so as to evacuate the space where the objects to be dried are located through the vacuum pump 381.

When the vacuum is pumped, the air pumping control valve 383 and the air pumping switch valve 742 are opened, the space of the liquid cooling cabinet is vacuumized through the vacuum pump 381, whether the vacuum degree inside the cavity reaches the standard or not can be displayed through the vacuometer 741, the standard of the vacuum degree can be set in advance, the air pumping switch valve 742 can be closed when the vacuum degree reaches the standard, and then the drying operation is carried out. The vacuum filter 382 is used to filter out impurities, so as to prevent impurities such as moisture or oil stain inside the cavity from entering the vacuum pump 381 to damage the vacuum pump 381 during vacuum pumping. The vacuumizing control valve 383 can cut off vacuumizing, and when a component between the vacuumizing control valve 383 on the vacuumizing pipeline 38 and a cavity to be dried breaks down, vacuumizing can be suspended through the vacuumizing control valve 383, so that the broken component can be maintained conveniently.

Through vacuum pump 381 evacuation processing for the inside vacuum environment that forms of liquid cooling rack, under vacuum environment, the boiling point etc. of water can reduce, when the stoving gas of reuse predetermined temperature dries the liquid cooling rack, the moisture of cavity inside can evaporate quicker, with the increase drying efficiency.
