Abstract

A cooling device is provided to reduce the power consumption by making refrigerant which passes through a compressor cooled via a heat exchanger and supplied to a condenser. A cooling device comprises a condenser(100), an expansion valve(200), an evaporator(300), a heat exchanger(500) and a compressor(400). The refrigerant passing through the condenser is flowed in into the expansion valve and then is introduced into the evaporator. The heat exchanger overheats the refrigerant coming out of the evaporator. The refrigerant passing through the heat exchanger is flowed into the compressor and then is supplied to the condenser.
