Patent ID: 8161644

Claim:
A leveling method for burying an evaporating section of a heat pipe into a thermally conductive seat, including following steps: a) preparing at least one heat pipe ( 1 ), a thermally conductive seat ( 2 ) to be thermally connected to the heat pipe ( 1 ), and arrange at least one groove ( 21 ) at a bottom surface ( 20 ) of the thermally conductive seat ( 2 ) for burying an evaporating section ( 10 ) reserved in the heat pipe ( 1 ) therein; b) laying the evaporating section ( 10 ) of heat pipe ( 1 ) into the groove ( 21 ) of the thermally conductive seat ( 2 ) for being fixed in a fixture ( 3 ) together; c) disposing the fixture ( 3 ) of step b) onto a stamping machine ( 4 ) that includes: a platform ( 40 ), on which a plurality of machining positions ( 400 , 401 , 402 , 403 ) for sequentially positioning the fixture ( 3 ) are provided; and a punch ( 41 ), which is arranged above the platform ( 40 ) and interspaced the platform ( 40 ) correspondingly, and which process a pressing down motion toward the platform ( 40 ), and on which a plurality of pressing dies ( 410 , 411 , 412 , 413 ) are arranged, which correspond to each machining position ( 400 , 401 , 402 , 403 ) respectively, and each under face of which is a press-fitting surface ( 410 a , 411 a , 412 a , 413 a ) formed, on which an indentation ( 410 b , 411 b , 412 b ) is formed with a depth varying from deepness to shallowness according to the sequence of each machining position ( 400 , 401 , 402 ), and a last one of which ( 413 a ) is a flat surface; d) according to the stamping machine ( 4 ) of step c), the fixture ( 3 ) being laid onto each machining position ( 400 , 401 , 402 , 403 ) in sequence, at each machining position, making each pressing die ( 410 , 411 , 412 , 413 ) execute a pressing down motion to the evaporating section ( 10 ) of the heat pipe ( 1 ) on the fixture ( 3 ), thereby, a flat surface ( 100 ) being gradually formed on a top of the evaporating section ( 10 ).
