PURPOSE:To improve the performance of a heat pipe, by welding many hollow metal tubes having a small diameter to the inner wall surface of a group type container, and cutting the tube walls at the portions thereof located at a heat emitting section and a heat absorbing section so that they are opened toward the center of the container. CONSTITUTION:Hollow metal tubes 2, small in its thickness and diameter, are at first manufactured by way of extrusion or other method, and a hollow metal tube group is formed by inserting the tubes 2 into a container 1 in a straight or spiral manner and in a side-by-side relationship with each other, and welding (at 4) them to the inner wall surface of the container 1. Then, the tubes 2 are cut at their wall portions located at a heat absorbing section A and a heat emitting section C and facing the center of the container 1, so that they are opened toward the center of the container 1. Here, the sectional form of the openings is determined to suit the use of the heat pipe. In such an arrangement, condensed liquid at the section C is introduced into the tubes 2 from the openings and carried through an intermediate section B. Then, it is evaporated at the section A and discharged into the container 1 from the openings. Thus, it is enabled to improve the performance of the heat pipe. |
