METHOD FOR MANUFACTURING A HEAT PIPE HAVING AN ENLARGED PORTION |
摘要 |
A method for manufacturing a heat pipe having an enlarged portion includes the steps of: preparing a hollow tubular material having a uniform outer diameter; forming the tubular material with an enlarged portion having a different or larger outer diameter by narrowing or enlarging the tubular material; arranging a capillary structure into the tubular material; filling a working fluid into the tubular material after sealing one end of the tubular material; sealing the end to form a heat pipe after performing a degassing operation; and pressing the enlarged portion obtained in the previous step to form a flattened enlarged portion on the heat pipe.
