Heat pipe structure having circuitous capillary tissue

Abstract

A heat pipe having a circuitous capillary tissue includes a pipe body and a capillary tissue installed in the pipe body. The interior of the pipe body is formed with a vapor flow channel which is hollow and extended towards the length direction thereof, and a working fluid is stored therein; the capillary tissue is formed with a primary capillary part, two secondary capillary parts, and communicating capillary parts connected between the primary and the secondary capillary parts; wherein, the two secondary capillary parts are both extended along the length direction of the pipe body and respectively abutted against two lateral walls extended along the length direction of a pipe member, and two sides of the primary capillary part are both formed with a space allowing the vapor flow channel to be kept.

What is claimed is: 
     
         1 . A heat pipe structure having a circuitous capillary tissue, including:
 a pipe body, formed with a pipe member and two end parts respectively sealing two ends of the pipe member, wherein the interior of the pipe member is formed with a vapor flow channel which is hollow and extended along a length direction thereof, and a working fluid is stored therein; and   a capillary tissue, installed in the pipe body, and formed with a primary capillary part, two secondary capillary parts and two communicating capillary parts which are all formed in a strip-like shape and pass the vapor flow channel, wherein the communicating capillary parts are connected between the primary and the secondary capillary parts thereby continuously forming a circuitous status;   wherein, the two secondary capillary parts are both extended along the length direction of the pipe body and respectively abutted against two lateral walls extended along the length direction of the pipe member, and two sides of the primary capillary part are both formed with a space allowing the vapor flow channel to be kept.   
     
     
         2 . The heat pipe structure having the circuitous capillary tissue according to  claim 1 , wherein a cross section of the pipe body is formed in a flat status. 
     
     
         3 . The heat pipe structure having the circuitous capillary tissue according to  claim 1 , wherein the thickness of the pipe body is smaller than 0.6 mm. 
     
     
         4 . The heat pipe structure having the circuitous capillary tissue according to  claim 1 , wherein the capillary tissue is formed as a strip-like member through sintering powders, weaving fibers or metal wires or reeling a metal net. 
     
     
         5 . The heat pipe structure having the circuitous capillary tissue according to  claim 1 , wherein the two communicating capillary parts of the capillary tissue are respectively abutted against an inner partial portion respectively defined at the two end parts. 
     
     
         6 . The heat pipe structure having the circuitous capillary tissue according to  claim 1 , wherein the two communicating capillary parts of the capillary tissue are respectively formed in an arc-like status or a linear status. 
     
     
         7 . The heat pipe structure having the circuitous capillary tissue according to  claim 1 , wherein each of the two secondary capillary parts of the capillary tissue is formed with an auxiliary capillary part extended from a free end thereof. 
     
     
         8 . The heat pipe structure having the circuitous capillary tissue according to  claim 7 , wherein the auxiliary capillary part is further extended with an abutting segment towards the primary capillary part thereby being abutted against the primary capillary part, so the capillary tissue is further formed in a loop-like status. 
     
     
         9 . The heat pipe structure having the circuitous capillary tissue according to  claim 7 , wherein the auxiliary capillary part is formed in an arc-like status or a linear status.
