Flat heat pipe with multi-passage sintered capillary structure

Abstract

The flat heat pipe with multi-passage sintered capillary structure includes a flat pipe, which is a hollow pipe with a flat cross section and two sealed ends. Two flat surfaces and two lateral parts are defined. The flat pipe forms a heating section and a cooling section. A hollow chase is formed within the flat pipe. The sintered capillary structure is prefabricated into the hollow chase and is provided with at least two coupling sides for mating with two flat surfaces of the flat pipe. At least two flow passages are formed at intervals onto a preset location of the sintered capillary structure and arranged along the extension direction of the flat pipe.

1 . A flat heat pipe with multi-passage sintered capillary structure, comprising:
 a flat pipe, being hollow and having a flat cross section and two sealed ends, defining two flat surfaces and two lateral parts, said flat pipe having a heating section and a cooling section, and a hollow chase formed therein;   a sintered capillary structure, being prefabricated into a hollow chase of said flat pipe, said sintered capillary structure being provided with at least two coupling sides mated with said two flat surfaces of said flat pipe; and   at least two flow passages, formed at intervals onto a preset location of said sintered capillary structure and arranged along an extension direction of said flat pipe.   
   
   
       2 . The flat heat pipe defined in  claim 1 , wherein the circumference of sintered capillary structure is filled into the inner wall of hollow chase of the flat pipe. 
   
   
       3 . The flat heat pipe defined in  claim 1 , wherein said flow passages are formed within said sintered capillary structure. 
   
   
       4 . The flat heat pipe defined in  claim 1 , wherein said flow passages are formed between said sintered capillary structure and a flat surface of said flat pipe. 
   
   
       5 . The flat heat pipe defined in  claim 1 , wherein said flow passage is provided with a mesh body or porous components. 
   
   
       6 . The flat heat pipe defined in  claim 1 , wherein said flat piper further comprises grooves formed on an inner wall of said hollow chase of said flat pipe. 
   
   
       7 . The flat heat pipe defined in  claim 1 , further comprising:
 a space shaped between said sintered capillary structure and one end of the cooling section, said flow passage being provided with a connecting space at an end thereof.
