METHOD FOR MANUFACTURING A PLATE-TYPE HEAT PIPE AND A PLATE-TYPE HEAT PIPE OBTAINED THEREBY
First Claim
1. 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.

Abstract
A method for manufacturing a plate-type heat pipe includes providing an elongated engaging plate and a base plate. A plurality of supporting members is secured on a top surface of the base plate. A second and third metal powders are filled onto the base plate, surrounding lower ends of the supporting members. The second and third metal powders are heated to obtain a first wick structure and a second wick structure. The first wick structure adheres to the top surface of the base plate and the second wick structure adheres to the top surface of the first wick structure. The base plate and the supporting members are secured to a bottom surface of the engaging plate to obtain a workpiece. A working fluid is injected into the workpiece and the workpiece is vacuumed to obtain the plate-type heat pipe.

11. A plate-type heat pipe comprising:
-
a base plate defining a trough in a top surface thereof; an engaging plate secured on the top surface of the base plate over the trough; a plurality of supporting members interconnects the top surface of the base plate in the trough and a bottom surface of the engaging plate for reinforcing a strength of the plate-type heat pipe; a first wick structure provided on the top surface of the base plate in the trough; a second wick structure provided on a top surface of the first wick structure, wherein the second wick structure has a pore size larger than that of the first wick structure. - View Dependent Claims (12, 13, 14, 15, 16)
