Thin plate heat pipe

Abstract

Disclosed is a thin film heat pipe suitable for removal of hot spots in displays such as an LCD, an LED, and a PDP. An exemplary embodiment of the present disclosure provides a thin plate heat pipe including: a body part having a flat plate shape; a through-hole formed in the body part in a longitudinal direction; a plurality of grooves formed on the inner wall of the through-hole and in which a working fluid flows; and a wick formed in at least a part of the through-hole.

1 . A thin plate heat pipe, comprising:
 a body part having a flat plate shape;   a through-hole formed in the body part in a longitudinal direction;   a plurality of grooves formed on the inner wall of the through-hole and in which a working fluid flows; and   a wick formed in at least a part of the through-hole.   
     
     
         2 . The thin plate heat pipe of  claim 1 , wherein the through-hole is separated by one or more separation membranes. 
     
     
         3 . The thin plate heat pipe of  claim 1 , wherein the groove has a shape including one or more edges. 
     
     
         4 . The thin plate heat pipe of  claim 1 , wherein the wick is inserted into an evaporator section of the thin plate heat pipe. 
     
     
         5 . The thin plate heat pipe of  claim 1 , wherein the wick is one of a sintered wick or a fabric wick. 
     
     
         6 . The thin plate heat pipe of  claim 5 , wherein the sintered wick is inserted into the through-hole separated by one or more separation membranes formed in the through-hole. 
     
     
         7 . The thin plate heat pipe of  claim 6 , wherein the sintered wick is made of metal or ceramic. 
     
     
         8 . The thin plate heat pipe of  claim 5 , wherein the fabric wick is integrally inserted into the through-hole. 
     
     
         9 . The thin plate heat pipe of  claim 1 , wherein the inside of the through-hole is maintained in a vacuum state. 
     
     
         10 . The thin plate heat pipe of  claim 1 , wherein the thin plate heat pipe is installed at an incline or vertically. 
     
     
         11 . The thin plate heat pipe of  claim 1 , wherein the heat pipe is made of copper or aluminum. 
     
     
         12 . The thin plate heat pipe of  claim 1 , wherein the thickness of the heat pipe is 2 mm or less.
