Abstract

PURPOSE: To obtain a sealing with leakage lessened and in which there is no restriction of heating temperature, by such a construction that a ball is pushed into the injection tube from its opening to choke the injection tube.
CONSTITUTION: A heat pipe roll 2 is formed in such a construction that an injection tube 3 consisting of a copper tube is inserted into the side plate 2c and fixed by brazing. The opening part 3a of the injection tube 3 shall be provided with chamfering so that a ball 4 can be easily pushed in. For ex. a ball 4 of 1.1W1.5mm in diameter is pushed into an injection tube 3 of 1mm in inner diameter so that no gap will be produced between the ball 4 and the injection tube 3. In case a sufficient sealing can not be expected only by pushing in tightly, an appropriate process shall be applied such as crushing the extra portion at the tip of injection tube 3, or pouring solder, adhasive, etc. 7 into that portion to fix it. By this method a sealing with less leakage and no restriction of heating temp. can be obtained.
