Horizontal two-phase loop thermosyphon with capillary structures

Abstract

An apparatus for maintaining two-phase fluid circulation is disclosed, which includes a two-phase loop containing at least one condenser and at least one evaporator with a capillary structure therein.

We claim:  
     
         1 . An apparatus for maintaining two-phase fluid circulation, comprising a two-phase loop thermosyphon including at least one condenser and at least one evaporator with a capillary structure therein, wherein the capillary structure includes an extension in contact with the inner surface of the heated wall of the evaporator which extends above the liquid pool level in the evaporator.  
     
     
         2 . The apparatus as recited in  claim 1 , wherein the condenser is connected to the evaporator.  
     
     
         3 . The apparatus as recited in  claim 1 , further comprising two flow transport channels.  
     
     
         4 . The apparatus as recited in  claim 1 , wherein the evaporator includes multiple channels.  
     
     
         5 . The apparatus as recited in  claim 4 , wherein the diameter of the channels is of a size of vapor bubbles formed in the evaporator.  
     
     
         6 . The apparatus as recited in  claim 3 , wherein the capillary structure includes a barrier separating the inlets of the flow transport channels from the evaporator outlets.  
     
     
         7 . The apparatus as recited in  claim 1 , wherein the apparatus is formed by bonding two stamped parts.  
     
     
         8 . The apparatus as recited in  claim 4 , wherein the multiple channels in the evaporator are contained in the capillary structure.
