PROBLEM TO BE SOLVED: To provide a non-drain type cooling unit which can cope with condensate water generated from an evaporator without draining the condensate water.SOLUTION: A cooling unit 1 includes a refrigerant circuit R in which a compressor 6, a radiator 7, an expansion valve 8, and an evaporator 9 are sequentially connected by piping in a loop. An evaporation temperature of refrigerant in the evaporator 9 is higher than the freezing point. The cooling unit 1 also includes an evaporation dish 17 for receiving condense water generated in the evaporator 9, and a drain water pipe 21 which guides the condense water from the evaporator 9 to the evaporation dish 17. The cooling unit allows a discharge pipe 22 from the compressor 6 to the radiator 7, and the drain water pipe 21 to exchange heat with each other.SELECTED DRAWING: Figure 4 |
