Abstract

PURPOSE: To prolong the life of the heat pipe and reduce the cost thereof by forming the main structure of a heat pipe by a clad pipe formed by tightly bonding an inner pipe made of copper to an outer pipe made of an aluminized steel.
CONSTITUTION: The main structure of the heat pipe is formed by a clad pipe formed by tightly bonding the inner pipe 1 to the outer pipe 1. Copper which has no fear of being corroded due to an working fluid, is used in the inner pipe 1, and an aluminized steel which has no fear of being oxidized due to high temperature heating, is used in the outer pipe 1. The process for manufacturing the clad pipe comprises: a fitting step of fitting the inner and outer pipes 1 and 2 to each other; a step of comprising sealing a substance for increasing the inner pressure within the fitted pipe, and tightly closing both ends with caps; a step comprising heating the tightly closed pipe is vacuum to increase the internal pressure, softening the inner pipe 1 and tightly bonding the same to the outer pipe 2, and then expanding and bonding both pipes 1 and 2; and a step of opening both ends of the tightly closed pipe.
