Patent ID: 7536784

Claim:
A sintering method for a wick structure of a heat pipe, comprising the steps of: providing a pipe body ( 2 ) having an open end ( 21 ) and a shrunk end ( 22 ); providing a filling tool ( 4 ) with a clamping section ( 42 ) and assembling the clamping section ( 42 ) to the open end ( 21 ); inserting a shaft ( 3 ) inside the pipe body ( 2 ) such that a tapered head ( 31 ) of the shaft ( 3 ) is assembled to the shrunk end ( 22 ) to achieve a second positioning point, wherein another end of the shaft ( 3 ) extending to the filling tool ( 4 )forms a first positioning point corresponding to the clamping section ( 42 ); and filling a wick structure ( 6 ) into a gap ( 5 ) defined between the shaft ( 3 ) and the pipe body ( 2 ), sintering the wick structure ( 6 ) and cooling the wick structure ( 6 ) to complete a heat pipe having wick structure ( 6 ) of uniform thickness, wherein the clamping section ( 42 ) comprises a plurality of adjusting elements ( 43 ) to provide clamping action and position adjustment.
