Cooling apparatus for high-temperature medium by boiling and condensing refrigerant

A cooling apparatus for cooling a heat-emitting body by means of heat transport effected by boiling and condensing refrigerant, comprising:

• a refrigerant tank containing liquid refrigerant;
• a condensing vessel having a refrigerant tube into which vapor refrigerant boiled by heat from the heat-emitting body flows, for condensing the vapor refrigerant flowing through said refrigerant tube;
• and
• a pair of connecting members connecting said refrigerant tank with said refrigerant tube, wherein
• said refrigerant tank and said refrigerant tube are extruded members each provided in a hollow shape having two open ends and are disposed substantially parallel and pointing in a same direction,
• said pair of connecting members consists of a connecting member to which one open end of said refrigerant tank and one open end of said refrigerant tube are both connected, and another connecting member to which the other open end of said refrigerant tank and the other open end of said refrigerant tube are both connected, and
• said connecting members are each made by joining together two press-formed components.
