Loop vapor chamber conducive to separation of liquid and gas

Abstract

A loop vapor chamber conducive to separation of liquid and gas includes a base, an upper lid, a wick structure and a working fluid. The base includes a first recess, a second recess, a first extension channel and a second extension channel. The first recess and the second recess are in communication with each other through the first extension channel and the second extension channel. The upper lid is coupled to the base. The first recess, the second recess, the first extension channel and the second extension channel together form a closed space. The wick structure is disposed in the closed space and thus corresponds in position to the first recess, the second recess and the first extension channel.

         6 . The loop vapor chamber conducive to separation of liquid and gas according to  claim 1 , wherein rims of the first recess and the second recess define a first side, a second side, a third side and a fourth side respectively and sequentially, with the first extension channel connected to the third side of the first recess and the first side of the second recess, and the second extension channel connected to the fourth side of the first recess and the fourth side of the second recess. 
     
     
         7 . The loop vapor chamber conducive to separation of liquid and gas according to  claim 1 , wherein the wick structure comprises a first wick layer, a second wick layer, a third wick layer, a fourth wick layer and a wick, with the first wick layer formed at the upper lid and disposed at a corresponding portion of the first recess, the first wick layer not affecting communication between the first recess, the first extension channel and the second extension channel, with the second wick layer formed at the upper lid and disposed at a corresponding portion of the second recess, the second wick layer not affecting communication between the second recess, the first extension channel and the second extension channel, with the third wick layer formed at the base and disposed in the first recess, the third wick layer not affecting communication between the first recess, the first extension channel and the second extension channel, with the fourth wick layer formed at the base and disposed in the second recess, the fourth wick layer not affecting communication between the second recess, the first extension channel and the second extension channel, with the wick disposed in the first extension channel to fill at least a portion of the first extension channel fully. 
     
     
         8 . The loop vapor chamber conducive to separation of liquid and gas according to claim  7 , wherein the first wick layer, the second wick layer, the third wick layer and the fourth wick layer are made of copper powder or mesh, and the wick is made of copper powder or fibers. 
     
     
         9 . The loop vapor chamber conducive to separation of liquid and gas according to  claim 7 , wherein the wick extends across the first recess and the second recess. 
     
     
         10 .
