Abstract
PURPOSE: To obtain a highly precise quantity of working liquid, prevent air penetration and make properties uniform by providing a valve at the top of an unfinished heat pipe, inserting the bottom into a working liquid inside a tank, replacing an air inside an unfinished pipe with a working liquid vapor from the valve and finally introducing the working liquid into the unfinished pipe.
CONSTITUTION: A three-point valve 9 is provided at the top of an unfinished heat pipe 1 and the bottom is inserted into a working liquid inside a liquid tank 11 up to a position to meet a hermetically contained quantity. Then a working liquid vapor 5a is introduced into the unfinished pipe 1 from a channel 10a. Next, a tubular passage 10a is closed and a tubular passage 10a is opened to expose the unfinished pipe 1 to an atmosphere. Consequently the working liquid 5 inside a liquid tank 11 flows into the unfinished pipe 1, pushing up a working liquid 5a inside and discharging a vapor through a flow passage 10b. When a prearranged hermetically contained quantity is filled, a valve 9 is closed and the unfinished pipe 1 is pulled out of a liquid tank as it is. Following this procedure, the upper and lower ends are pressed, sealed and cut. In this manner, it is possible to obtain a highly precise quantity of hermetically contained working liquid, prevent air penetration and make properties uniform.
