Abstract
PURPOSE: To reduce electric power consumption and improve working efficiency in the manufacture of a double walled type heat pipe used, for example, for the fixing roll of a copying machine by pouring a working fluid in a vacuumed double tube heat pipe container, and performing deaeration and sealing while heating.
CONSTITUTION: A container 5 for a double walled tube heat pipe is held on an indexing table 1, the space between inner and outer walls of the container 5 is made negative in pressure by way of a vacuum pump 14, then a predetermined amount of a working fluid is poured through a metering instrument 13 and a 3-way valve 12 into the container 5. Then rotation of the index table 5 is started, a heater 56 is inserted through a through hole in a shaft 53 into the container 5, and the vacuum pump 14 is operated again as well as heated by the heater 56 to reduce the pressure to a predetermined value and perform deaeration. Then the tube is crushed by a jaw 22 to be sealed up and is cut. Said method allows power consumption to be reduced and working efficiency to improve.
