PURPOSE:To make it possible to manufacture the titled heat exchanger in one manufacturing step by bonding the vicinities of end portions of neighboring tubular bodies by means of connecting pipes to constitute tubular body groups, disposing a plurality of tubular body groups, and coupling communicating pipes of the plurality of tubular groups by means of a connecting pipe to form an integral body. CONSTITUTION:The diameter of each of communicating pipes 8 is made smaller than that of each of heat pipes 7. For instance, the communicating pipes 8 penetrate through the vicinities of the end portions of the heat pipes 7. The penetrating parts of the communicating pipes 8 are sealed by welding and the like. The communicating pipe 8 positioned in the heat pipe 7 is provided with communicating holes 8a. A plurality of heat pipes 7 are integrally coupled. Accordingly, when the steps of evacuation, pouring of a working liquid 9 and sealing thereof are carried out once from any one of tubular body groups consisting of a plurality of heat pipes 7, and communicating pipes 8, the tubular body groups are all subjected to evacuation, pouring of the working liquid and sealing thereof. |
