Multi-pipe three-dimensional plusating heat pipe

Abstract

A multi-pipe three-dimensional pulsating heat pipe includes at least two pipes and at least two chambers. The at least two pipes form into respective three-dimensional annular loops. A cooling zone is formed to one side of the annular loops. Two opposing ends of the at least two pipes are connected spatially to the at least two chambers, respectively, so as to form the multi-pipe three dimensions pulsating heat pipe.

What is claimed is: 
     
         1 . A multi-pipe three-dimensional pulsating heat pipe, comprising:
 at least two pipes, each of the at least two pipes being formed into three-dimensional annular loops, at least one side of the annular loops being defined as a cooling area; and   at least two chambers, connecting respectively and spatially to two opposing ends of each of the at least two pipes so as to form the multi-pipe three-dimensional pulsating heat pipe.   
     
     
         2 . The multi-pipe three-dimensional pulsating heat pipe of  claim 1 , wherein each of the at least two pipes is a metallic pipe or a non-metallic pipe. 
     
     
         3 . The multi-pipe three-dimensional pulsating heat pipe of  claim 1 , wherein the three-dimensional annular loops are symmetric structures or asymmetric structures. 
     
     
         4 . The multi-pipe three-dimensional pulsating heat pipe of  claim 1 , wherein the at least two pipes have the same diameter or cross-sectional area. 
     
     
         5 . The multi-pipe three-dimensional pulsating heat pipe of  claim 1 , wherein the at least two pipes have different diameters or cross-sectional areas. 
     
     
         6 . The multi-pipe three-dimensional pulsating heat pipe of  claim 1 , wherein the three-dimensional annular loops include an outer-frame portion and a central empty portion. 
     
     
         7 . The multi-pipe three-dimensional pulsating heat pipe of  claim 6 , further including a heating source located at one side of the outer-frame portion. 
     
     
         8 . The multi-pipe three-dimensional pulsating heat pipe of  claim 6 , further including an anchorage member located in the central empty portion. 
     
     
         9 . The multi-pipe three-dimensional pulsating heat pipe of  claim 8 , wherein the anchorage member is one of a circuit, a mechanism and a heat-dissipation member. 
     
     
         10 . The multi-pipe three-dimensional pulsating heat pipe of  claim 1 , wherein each of the at least two pipes is filled with a work fluid; wherein, while the work fluid is heated, the multi-pipe three-dimensional pulsating heat pipe is operable in a horizontal or a negative-angling state. 
     
     
         11 . The multi-pipe three-dimensional pulsating heat pipe of  claim 1 , wherein one side of the annular loops is defined as an evaporation zone, while another side of the annular loops is defined as a condensation zone. 
     
     
         12 . The multi-pipe three-dimensional pulsating heat pipe of  claim 1 , wherein the annular loops are rectangular, trapezoidal or triangular shaped.
