Abstract:
1. A micro-spray cooling system for a plurality of heat sources, comprising: an evaporator contacting the plurality of heat sources, comprising and at least one storage chamber and a plurality of piezoelectric actuators corresponding to the plurality of heat sources; a condenser connected to the evaporator; and at least one driving circuit connected to the piezoelectric actuators to drive some or all of the piezoelectric actuators sequentially according to a predetermined timing to cool the plurality of heat sources, wherein refrigerant stored in the at least one storage chamber of the evaporator is sprayed by the piezoelectric actuators to thermally contact the plurality of heat sources, evaporated by heat from the plurality of heat sources, condensed in the condenser, and re-enters the evaporator, and wherein the driving circuit controls a vibration amplitude and a frequency of the piezoelectric actuators, and a negative pressure generated in the at least one storage chamber by the vibration of the piezoelectric actuators enables the refrigerant to flow from the condenser into the at least one storage chamber.
