PURPOSE:To prevent a heat transfer loss between a heat pipe and fins in view of its heat transfer by a method wherein the heat pipe is comprised of a predetermined rectangular-shaped bottom part (an evaporating part) and a predetermined upper surface lid (a condensing part). CONSTITUTION:A flat circular heat pipe is a rectangular in its shape and has a circular bottom. A side surface 3 of an inner surface is formed with a V-shaped part at the evaporating part of the heat pipe, and a bottom surface 2 at the inner surface is formed with a spider-like or approximate cross-like fine V-shaped groove formation. Then, a corner part 4 between the bottom surface and the side surface is provided with a V-shaped deep groove. Then, the upper surface lid 5 of the container is a metallic product acting as a lid part to be fixed to the case 1. The inner surface 6 of the circular metallic plate has vane-like heat absorption plate perpendicular to the lid plate at a part corresponding to the condensing part of the inner side of the heat pipe of the closed pipe. It is machined with the same metal as that of the lid, a vane of the metallic plate for use in increasing a heat absorption area of the condensing part is also provided. Corner portions of the roots of the metallic plate and the lid metal are used as a liquid returning group for the condensing part and they are used as fins 7, thereby a heat radiation capability is increased. |
