摘要： The present invention relates to a cooling apparatus for an electronic device. In the present invention, a coolant passing through a condenser 10 is introduced into and s filled in a compensator 15. The coolant passing through the compensator 15 is introduced into a vaporizer 20 and vaporized through heat exchange with an auxiliary heat source H2 provided outside of the vaporizer. In addition, a vaporizing unit 22 made of a porous material is provided in the vaporizer 20. The coolant passing through the vaporizer 20 and a liquid coolant supplied from the condenser 10 are mixed in a vortex generating unit 30 to form a coolant spray, and the coolant spray moves along a spiral trajectory to be formed into a vortex. Meanwhile, the coolant spray of a vortex is injected to be in close contact with the inner wall of an evaporator 50 to be heat-exchanged with a main heat source H1 positioned outside of the evaporator, thereby cooling the main heat source H1. According to the present invention as mentioned above, the main heat source adjacent to the evaporator is heat-exchanged with the coolant more actively to thereby improve the cooling performance of the electronic device. Also, a pressure loss of the coolant spouted from the venturi tube is further reduced.
