Abstract
A cooling system for electronic devices comprises a first heat exchanger, a second heat exchanger, a third heat exchanger, a first coolant pipe, a circulating pump and a second coolant pipe. The first heat exchanger is provided with coolant which absorbs heat generated by an electronic device. The third heat exchanger heats up liquefied gas by seawater. The seawater subjected to heat exchange flows through the second heat exchanger to absorb heat of the coolant flowing through the second heat exchanger so as to cool the coolant. The circulating pump powers for transmission of the coolant. The coolant flowing through the first heat exchanger absorbs the heat generated by the electronic device, the third heat exchanger cools the seawater by gasification of the liquefied gas, the cooled seawater is transmitted to the second heat exchanger to absorb the heat of the coolant flowing through the second heat exchanger so as to cool the coolant, and accordingly the electronic device is cooled while the liquefied gas is gasified. The cooling system for electronic devices meets the requirements of today's society for energy conservation and emission reduction.
