Abstract
A method for manufacturing a plate-type heat pipe includes providing a mold including a first cavity and a plurality of second cavities and depositing cores into the mold. Each core has a first portion in the first cavity and a second portion in a corresponding second cavity. First and second metal powder are filled into the mold. The cores are then removed from the mold to form a green piece by the first and second metal powder, which has first and second chambers therein. The green piece is sintered, whereby the first metal powder forms an outer wall of the heat pipe and the second metal powder forms a wick structure. The heat pipe has a heat absorbing portion having the first chambers and fins having the second chambers communicating with the first chambers.
