れないという欠点があった。[Prior Art] Conventionally, in the case of a pipe in which the distal end of a straight pipe was caulked (so-called caulking J), the cross section of the straight pipe part became oval due to the influence of caulking pressure. However, there was a drawback that the length of the part where the outer diameter was uniform, and the effective length could not be made long.

しまうものである。'' is a heat pipe whose end is drawn to a small diameter and then caulked, and a working fluid is sealed inside the heat vibrator 1. When caulking the tube end of such a heat pipe 1, the initially determined length of the straight pipe part [,] becomes shorter due to the caulking process, and the effective length l of the straight pipe part [,] becomes shorter. It will become.

することにより直管部の断面が楕円になるためである。This is done by caulking 3 the pipe end 2 which has been drawn to a small diameter.
This is because the cross section of the straight pipe portion becomes elliptical.

本発明を図面について説明する。[Problems to be Solved by the Invention] The present invention was developed as a result of various researches in view of the above-mentioned circumstances, and it applies pressure to the pipe ends by changing their positions in the vertical and horizontal directions, thereby improving the effectiveness of the heat pipe. [Means for Solving the Problems] The present invention will be described with reference to the drawings.

It is a diagram showing l'-. First, the portion 12 to be caulked and pressurized is flattened. Figure 2 (a') is obtained by performing flat addition -L.
As shown, the processing direction (indicated by the arrow) is flattened, and the hole 13 of the heat pipe block 1 is also flattened. Then the second
As shown in Figures (b) and (b'), flattening is performed in a direction perpendicular to the previous flattening direction. Then,
The hole 13 of the heat pipe 12 is also subjected to the flattening effect. The caulking portion of the tube end 11' of the heat pipe 11 which has been flattened in this way is caulked 14.

At this time, caulking is performed with the direction changed by 90 degrees from the direction of flattening.
