Heat pipe

Abstract

A heat pipe including a pipe body, a first capillary structure and a second capillary structure. The pipe body has an evaporation portion and a condensation portion. The condensation portion is connected to the evaporation portion. The first capillary structure is disposed in the evaporation portion. The second capillary structure is disposed in the condensation portion and is connected to an end of the condensation portion that is located away from the evaporation portion. The second capillary structure is not in direct contact with the first capillary structure.

What is claimed is: 
     
         1 . A heat pipe, comprising:
 a pipe body, having an evaporation portion and a condensation portion, the evaporation portion extends in a first direction, the condensation portion extends in a second direction, and a bent portion connects the condensation portion and the evaporation portion; and   a first wick, disposed in the evaporation portion and spaced apart from the condensation portion.   
     
     
         2 . The heat pipe according to  claim 1 , further comprising a second wick that is disposed in the condensation portion and is not in direct contact with the first wick. 
     
     
         3 . The heat pipe according to  claim 2 , wherein an end of the second wick adjacent to the evaporation portion is located on an end of the bent portion. 
     
     
         4 . The heat pipe according to  claim 2 , wherein there is not another wick between the second wick and the first wick. 
     
     
         5 . The heat pipe according to  claim 1 , wherein there is no wick disposed in the condensation portion. 
     
     
         6 . The heat pipe according to  claim 2 , further comprising a third wick, wherein the third wick is stacked on the first wick and is not in direct contact with the second wick.
