Heat dissipating assembly

Abstract

A heat dissipating assembly for dissipating heat of a heat source is provided. The heat dissipating assembly includes a body, at least one circulation pipe, and a working fluid. The body has a chamber defined therein and least one pipeline formed in a wall of the body. The body further has at least one first orifice in communication with the chamber of the body, and at least one second orifice in communication with the pipeline. The circulation pipe has two end portions respectively connected to the first orifice and the second orifice. The working fluid is accommodated in the chamber of the body, wherein the working fluid flows into the circulation pipe through the first orifice, and flows into the pipeline through the second orifice to flow back to the chamber of the body, thereby forming a two phase circulation loop.

1 . A heat dissipating assembly, for dissipating heat of a heat source, comprising:
 a body, having:
 a chamber defined therein; 
 a base used to contact the heat source; 
 at least one pipeline formed in a wall of the body and extending to the base; 
 at least one first orifice in communication with the chamber; and 
 at least one second orifice in communication with the pipeline; 
   at least one circulation pipe, having two end portions respectively connected to the first orifice and the second orifice; and   a working fluid, accommodated in the chamber of the body and being in contact with the base, wherein the working fluid is circulated between the circulation pipe and the chamber of the body.   
   
   
       2 . The heat dissipating assembly as claimed in  claim 1 , further comprising at least one fin assembly, wherein the circulation pipe penetrates through the fin assembly to fix the fin assembly to the circulation pipe and to have the fin assembly to exchange heat with the circulation pipe. 
   
   
       3 . The heat dissipating assembly as claimed in  claim 1 , wherein the body further comprises an injection hole for injecting the working fluid into the chamber of the body. 
   
   
       4 . The heat dissipating assembly as claimed in  claim 3 , further comprising an injection pipe, connected to the injection hole for the working fluid to flow through the injection hole and be injected into the chamber. 
   
   
       5 . The heat dissipating assembly as claimed in  claim 1 , wherein the base further has at least one flow channel formed on the surface of the base for guiding the working fluid. 
   
   
       6 . The heat dissipating assembly as claimed in  claim 1 , wherein the circulation pipe is parallel to the base of the body. 
   
   
       7 . The heat dissipating assembly as claimed in  claim 1  wherein the circulation pipe is perpendicular to the base of the body. 
   
   
       8 . The heat dissipating assembly as claimed in  claim 1 , wherein an inclined angle is formed between the circulation pipe and base of the body. 
   
   
       9 . The heat dissipating assembly as claimed in  claim 1 , wherein the base further has a capillary layer formed thereon for attracting the working fluid. 
   
   
       10 . The heat dissipating assembly as claimed in  claim 9 , wherein the capillary layer is a porous structure layer formed by sintered metal powder. 
   
   
       11 . The heat dissipating assembly as claimed in  claim 9 , wherein the metal powder is copper power.
