Pulsating heat pipe with flexible artery mesh

Abstract

A pulsating heat pipe ( 10 ) includes an elongate capillary tube ( 11 ), a working fluid ( 15 ) disposed within the elongate tube and an artery mesh ( 13 ) disposed in the elongate tube. The capillary tube includes a plurality of heat receiving portions ( 112 ) located on a first predetermined part of the elongate tube, and a plurality of heat radiating portions ( 114 ) located on a second predetermined part of the elongate tube. The heat receiving and heat radiating portions are alternatively disposed on the elongate tube. The working fluid is propelled to flow between the heat receiving and heat radiating portions via a first channel ( 132 ) defined in the artery mesh and a second channel ( 133 ) defined between the artery mesh and the elongate tube.

1 . A pulsating heat pipe comprising:
 an elongate capillary tube comprising a plurality of heat receiving portions located on a first predetermined part of the elongate tube, and a plurality of heat radiating portions located on a second predetermined part of the elongate tube, the heat receiving and heat radiating portions being alternatively disposed on the elongate tube;   a working fluid disposed within the elongate tube; and   an artery mesh disposed in the elongate tube, the working fluid being propelled to flow between the heat receiving and heat radiating portions via a first channel defined in the artery mesh and a second channel defined between the artery mesh and the elongate tube.   
   
   
       2 . The pulsating heat pipe of  claim 1 , wherein the artery mesh has an adjacent portion contacting with an inner wall of the capillary tube, and a distant portion spaced at a distance from the inner wall of the capillary tube. 
   
   
       3 . The pulsating heat pipe of  claim 1 , wherein the elongate capillary tube is hand-shaped in profile and has two terminals hermetically connected with each other to form a close looped flow passage of the working fluid. 
   
   
       4 . The pulsating heat pipe of  claim 1 , wherein the artery mesh is an elongate hollow tube formed by weaving a plurality of metal wires. 
   
   
       5 . The pulsating heat pipe of  claim 4 , wherein the metal wires are selected from a group consisting of copper wires and stainless steel wires. 
   
   
       6 . The pulsating heat pipe of  claim 1 , wherein the artery mesh comprises a plurality of spaced segments disposed in the entire elongate capillary tube. 
   
   
       7 . The pulsating heat pipe of  claim 1 , wherein the elongate capillary tube is made of deformable metallic materials. 
   
   
       8 . The pulsating heat pipe of  claim 1 , wherein the working fluid comprises a plurality of liquid segments and vapor bubbles alternately distributed along the elongate capillary tube. 
   
   
       9 . The pulsating heat pipe of  claim 1  further comprising a filling tube for filling and supplying the working fluid into the elongate capillary tube. 
   
   
       10 . The pulsating heat pipe of  claim 1  further comprising at least one pressure sensitive check valve disposed in a circulation passage of the working fluid for limiting flowing direction of the working fluid. 
   
   
       11 . A pulsating heat pipe comprising:
 an elongate tube;   working fluid received in the elongate tube and comprising liquid segments and vapor bubbles distributed between the liquid segments; and   an artery mesh received in the elongate tube, wherein a first channel for movement of the working fluid in the pulsating heat pipe is defined between an outer wall of the artery mesh and the an inner wall of the elongate tube, and a second channel for movement of the working fluid in the pulsating heat pipe is defined in the artery mesh.   
   
   
       12 . The pulsating heat pipe of  claim 11 , wherein the artery mesh has an adjacent side abutting against the inner wall of the elongate tube. 
   
   
       13 . The pulsating heat pipe of  claim 12 , wherein the elongate tube is made of one of aluminum and copper. 
   
   
       14 . The pulsating heat pipe of  claim 12 , wherein the artery mesh is formed by weaving metal wires. 
   
   
       15 . The pulsating heat pipe of  claim 14 , wherein the artery mesh is formed by weaving stainless steel wires. 
   
   
       16 . The pulsating heat pipe of  claim 14 , wherein the artery mesh is formed by weaving copper wires. 
   
   
       17 . The pulsating heat pipe of  claim 14 , wherein the artery mesh is formed by weaving a plurality of fiber together.
