When the temperature is low, the second liquid is used to cool down, and by reducing the amount of the second liquid, the energy consumption is reduced. After the cooling is completed, the high-pressure air is introduced into the main cooling channels 313 and the sub-cooling. The channel 613 is configured to discharge residual water and moisture to prevent water and moisture in the main cooling channel 313 from boiling when the temperature of the main body 31 and the sub-board body 61 is increased again, thereby reducing energy consumption and using The process is safer, so it can achieve the purpose of this new type.
