PURPOSE:To make it possible to manufacture the titled heat exchanger in one manufacturing step by coupling a plurality of neighboring tubular bodies to each other by means of communicating pipes each of which has a diameter which is larger than that of each of tubular bodies thereby to constitute tubular groups, disposing a plurality of tubular body groups, and coupling the communicating pipes of the plurality of the tubular body groups to each other by means of a connecting pipe, to form an integral body. CONSTITUTION:Communicating pipes 8 are integrally communicated and heat pipes 7 to constitute tubular body groups. A working liquid 9 such as flon, ammonia or the like is sealed into tubular body groups consisting of heat pipes 7 and communicating pipes 8 after being evacuated. Further, the diameter of each of the communicating pipes 8 is made larger than that of each of the heat pipes 7, and each communicating pipe is provided with communicating holes. Into the communicating holes are inserted the opening parts of the heat pipes 7. As a result, when the steps of evacuation, pouring of the working liquid, and sealing thereof are carried out once from any one place of the tubular body groups consisting of the 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. |
