PROBLEM TO BE SOLVED: To enhance cooling efficiency regarding a heat receiver, a cooling device using the same and an electronic apparatus using the same.SOLUTION: A protrusion part 23 formed by an upper surface plate 22 is configured so as to have a space gradually spreading in the horizontal direction from a refrigerant inlet 24 side to a middle part between the refrigerant inlet 24 and a refrigerant outlet 25, and to have a space gradually narrowing in the horizontal direction from the middle part to the refrigerant outlet 25. Thus, a liquid refrigerant is provided from the refrigerant inlet 24 side to an evaporation part 20 of a heat receiving plate 21 smoothly via a check valve 16, and a gaseous refrigerant evaporated in the evaporation part 20 flows out from the evaporation part 20 to the refrigerant outlet 25 smoothly. As a result, the speed of the refrigerant flowing in the evaporation part 20 becomes fast, and cooling efficiency can be enhanced. |
