Abstract: The cooling system allows the liquid coolant discharged from the pump to flow into the evaporation chamber. The liquid coolant passes through the atomizer. Minute droplets of the atomized coolant is discharged from the atomizer into the evaporation chamber. The minute droplets serve to form a uniform thin liquid film over the surface of the fin. Heat conducting from a target heat generating object to the fin promotes the evaporation of the liquid coolant over the surface of the fin, for example. The coolant absorbs a large amount of heat from the fin based on the evaporation. The target heat generating object can thus efficiently be cooled.

Besides, air inside the steel tub absorbs much water content due to heat exchange, and then the air with much water content and high temperature is cooled via the heat exchanger when passing through an air filter. After water content of the air is condensed, the air is reheated for using in next cycle.
