Abstract
A method of manufacturing a heat pipe, including the steps of: providing a hollow body with an open end and an opposite close end; filling a predetermined quantity of working fluid into the hollow body through the open end thereof after an interior of the hollow body having been evacuated to a predetermined vacuum degree; and sealing the open end of the hollow body.
Claims4
A method of manufacturing a heat pipe, comprising the steps of:
- providing a hollow body with an open end and an opposite close end;
- evacuating air in an interior of the hollow body through the open end to a predetermined vacuum;
- filling a predetermined quantity of working fluid into the hollow body through the open end thereof after the interior of the hollow body has been evacuated to the predetermined vacuum;
- and
- sealing the open end of the hollow body;
- wherein the predetermined quantity of working fluid is stored in a storage tank before the predetermined quantity of working fluid is filled into the hollow body, the storage tank being connected to the open end of the hollow body;
- wherein the degree of perfection of the predetermined vacuum in the hollow body is detected by a vacuum gauge, which is connected to the open end of the hollow body;
- wherein the predetermined vacuum degree of the interior of the hollow body is evacuated by a vacuum pump, which is connected to the open end of the hollow body;
- and
- wherein the open end of the hollow body is connected with the storage tank, the vacuum gauge and the vacuum pump through a trifurcate tube, wherein the vacuum pump, the liquid-storage tank and the vacuum gauge each communicate with the hollow body via three valves, respectively.
