Loop vapor chamber

Abstract

A loop vapor chamber includes: a base board having therein a space; a lid for covering the base board and sealing the space to form therein an evaporation chamber, vapor channel, condensation channel and liquid channel, the vapor channel having an end in communication with the evaporation chamber and another end in connection with the condensation channel, the condensation channel connecting to the liquid channel, and the liquid channel connecting to the evaporation chamber; a wick disposed in the evaporation chamber without occupying the evaporation chamber fully such that an evaporation space is defined in the evaporation chamber, the evaporation space being in communication with the vapor channel, wherein a portion of the wick corresponds in position to one end of the liquid channel; a space partition element disposed in the evaporation chamber to separate the evaporation space and liquid channel; and a working fluid filling the evaporation chamber.

What is claimed is: 
     
         1 . A loop vapor chamber, comprising:
 a base board having therein a space;   a lid for covering the base board and hermetically sealing the space to allow the space to have an evaporation chamber, a vapor channel, a condensation channel and a liquid channel, the vapor channel having an end in communication with the evaporation chamber and another end in connection with the condensation channel, the condensation channel being connected to the liquid channel, and the liquid channel being connected to the evaporation chamber;   a wick disposed in the evaporation chamber without occupying the evaporation chamber fully such that an evaporation space is defined in the evaporation chamber, the evaporation space being in communication with the vapor channel, wherein a portion of the wick corresponds in position to a terminal end of the liquid channel;   a space partition element disposed in the evaporation chamber to separate the evaporation space and the liquid channel; and   a working fluid filling the evaporation chamber.   
     
     
         2 . The loop vapor chamber of  claim 1 , wherein the base board has at least one channel partition element disposed in the liquid channel to partition the liquid channel into a plurality of fluid slug channels. 
     
     
         3 . The loop vapor chamber of  claim 2 , wherein the at least one channel partition element extends from the liquid channel into the condensation channel. 
     
     
         4 . The loop vapor chamber of  claim 3 , wherein the at least one channel partition element extends from the liquid channel into the condensation channel and the vapor channel. 
     
     
         5 . The loop vapor chamber of  claim 2 , wherein the fluid slug channels are of a smaller caliber than the vapor channel. 
     
     
         6 . The loop vapor chamber of  claim 1 , wherein the space partition element is made of a wick material and thus integrally formed with the wick, with the space partition element extending from the wick toward the lid to abut against the lid and extend into the liquid channel by a predetermined length. 
     
     
         7 . The loop vapor chamber of  claim 1 , wherein the wick is sintered-coupled to the base board and disposed at a bottom of the evaporation chamber, with evaporation space disposed between the wick and the lid, and the wick having a plurality of supportive blocks in contact with the wick and the lid. 
     
     
         8 . The loop vapor chamber of  claim 7 , wherein the plurality of supportive blocks is made of the same material as the wick and integrally formed with the wick. 
     
     
         9 . The loop vapor chamber of  claim 7 , wherein the plurality of supportive blocks is each a solid metal block. 
     
     
         10 . The loop vapor chamber of  claim 1 , wherein the space partition element is made of solid metal and abuts against the wick and the lid from below and above, respectively. 
     
     
         11 . The loop vapor chamber of  claim 1 , wherein the wick extends into the liquid channel by a predetermined length.
