Patent ID: 6863119

Claim:
A cooling device for boiling and condensing refrigerant to cool a heat-generating member, the cooling device comprising: a container for containing liquid refrigerant, the container including a heat reception wall onto which a heat-generating member is attached outside the container, and a heat radiation wall that is substantially parallel to the heat reception wall and disposed opposite to the heat reception wall; a heat conductor portion provided in the container, for thermally connecting the heat reception wall and the heat radiation wall; a heat radiation fin disposed outside the container to radiate heat generated from the heat-generating member to the outside through the heat reception wall, the heat conductor portion and the heat radiation wall; and a tube disposed around the heat radiation fin, to enclose the heat radiation fin within the heat radiation wall, wherein: the tube has two end portions disposed to communicate with an inner space of the container; and the two end portions of the tube extend through the heat radiation wall in a direction substantially perpendicular to the heat radiation wall and substantially perpendicular to the heat reception wall.
