PROBLEM TO BE SOLVED: To provide a cooling device which supplies a necessary amount of a refrigerant to a heat receiving part according to fluctuation of heat of a heating element to achieve stable cooling performance.SOLUTION: A cooling device 1 cools a heating element 2 with phase change of a refrigerant. In the cooling device 1, a heat receiving part 3 in which the heating element 2 is installed, a heat radiation passage 5, a heat radiation part 4, and a feedback path 6 are sequentially connected to form a circulation passage of the refrigerant. The feedback path includes a liquid tank. The liquid tank includes a first connection part and a second connection part. The liquid tank is detachably connected to the feedback path by the first connection part and the second connection part.SELECTED DRAWING: Figure 1 |
