PURPOSE:To enable a large quantity of heat to be transferred, by a method wherein the heat transfer at a heat-receiving part is effected by boiling heat transfer, and a porous boiling film is provided on the inside surface of the heat- receiving part. CONSTITUTION:The heat pipe 1 comprises a heat-releasing part 2 at an upper part thereof and the heat-receiving part 3 at a lower part thereof, with a medium 4 sealed therein. As the medium 4, a substance is selected which is boiled when heat is transferred to the medium 4 through the heat-receiving part 3. The boiling film 5 is provided on the inside surface of the heat-receiving part 3. The ilm 5 consists of a porous body, e.g., a cloth body formed from fibers, a metallic mesh body or a cloth form body formed from asbestos. Accordingly, since the heat transfer at the heat-receiving part 3 is boiling heat transfer, heat is transferred at high efficiency, and since growth of bubbles is accelerated by the presence of the film 5, heat is transferred at a still higher efficiency. |
