Method for manufacturing a plate-type heat pipe and a plate-type heat pipe obtained thereby

A method for manufacturing a plate-type heat pipe comprising:

• a) offering an elongated engaging plate and a base plate with a trough therein;
• b) securing a plurality of supporting members formed by sintering a first metal powder on a top surface of the base plate;
• c) filling a second metal powder and a third metal powder onto the base plate, the second and third powder enclosing bottom ends of the supporting members;
• d) heating the base plate and the second and third metal powder at a high temperature to obtain a first wick structure by the second metal powder and a second wick structure by the third metal powder, wherein the first wick structure securely adheres to the top surface of the base plate and the second wick structure securely adheres to the top surface of the first wick structure;
• e) securing the base plate and the supporting members to a bottom surface of the engaging plate to obtain a workpiece;
• and
• f) injecting a work fluid into the workpiece, vacuuming the workpiece, and hermetically sealing the sintered workpiece to obtain the plate-type heat pipe.
