In a cooling apparatus, a radiating part mounted on a refrigerant tank is made by stacking refrigerant tubes and fins alternately. A first header and a second header are provided at the ends of the refrigerant tubes. When the cooling apparatus is used in a vertical attitude, the first header is positioned above the liquid surface of refrigerant inside the refrigerant tank, and the second header is positioned below the liquid surface. Consequently, vapor refrigerant boiled by heat from a heat-emitting body attached to the refrigerant tank can flow through the first header into the refrigerant tubes, and liquid refrigerant liquefied in the refrigerant tubes can flow through the second header back to the refrigerant tank.

[ What is claimed is:] [1.] 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; anda pair of connecting members connecting said refrigerant tank with said refrigerant tube, whereinsaid 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, andsaid connecting members are each made by joining together two press-formed components.
