Abstract
A cooling device boiling and condensing refrigerant includes a refrigerant tank having a boiling space in which a part of liquid refrigerant is boiled and vaporized to gas refrigerant by absorbing heat from a heat-generating member, first and second radiators disposed at upper and lower parts of the refrigerant tank, defined by a liquid refrigerant surface within the refrigerant tank, and a connection pipe connecting the first and second radiators. The first and second radiators have the same shape, and are disposed to cool and condense gas refrigerant from the boiling space. In the cooling device, even when the cooling device is used in a normal state or a vertically reversed state, sufficient radiating performance of the first and second radiators can be obtained.
