Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a cooling device suppressing the deterioration of the cooling performance, which can supply a quantity of working fluid required for cooling, even when heat generated in a semiconductor-switching element in an inverter circuit of an electronic apparatus and an electronic vehicle is increased and the quantity of the working fluid required for cooling is increased.SOLUTION: The cooling device 3 circulates the working fluid 11 to cool it by phase change between a liquid phase and a vapor phase. The device includes a heat receiving part 4, a radiator 5, a radiation path 6, and a return path 7. A backflow valve 16 and a liquid reservoir 17 are provided on the return path 7. A large quantity of the working fluid 11 can be reserved, and thereby the cooling device 3 suppressing the deterioration of the cooling performance can be obtained which can supply the working fluid 11 to the heat receiving part 4, even when heat generated in the semiconductor-switching element 9 is increased and the quantity of the working fluid 11 required for cooling is increased. |
