Zusammenfassung: | PURPOSE:To facilitate the work by completing the preparatory work by processing a vent on a one-piece unit in which a whisker tube is eliminated and a sealing material is attached to the vent part. CONSTITUTION:A heater 11 for sealing work is arrached to a vent attachment vessel 1. The heater 11 performs the sealing work by means of an externally operated handle 4 through a bellows 3. A vent closure member 103 having a vent 104 in its center is attached to an end 102 of the heat pipe body 101. For the vent closure member 103, solder is normally used. After vacuum has been drawn from a vent pipe 2, the heater support rod 12 is lowered to bring the hot heater in contact with the vent 104 in the vent closure member 103 to heat it and seal off the vent 104. Therefore, the vacuumizing and sealing works can easily by performed by ordinary workers. |
