Heat absorber and its fabrication

Abstract

A heat absorber is constructed to have a heat-absorber plate and a liquid cooled tube, the liquid cooled tube being curved circuitously on a common plane that is closely attached to the top surface of the heat-absorber plate, and then welded to the top surface of the heat-absorber plate. By means of the design of the liquid cooled tube, heat-transfer fluid can flow through the liquid cooled tube, and no additional sealing gasket is necessary to prevent leakage.

1 - 5 . (canceled)  
   
   
       6 . A heat absorber structure comprising: 
 a heat-absorber plate, said heat-absorber plate having a top surface; and    a liquid cooled tube welded to the top surface of said heat-absorber plate, said liquid cooled tube being curved circuitously on a common plane that is closely attached to the top surface of said heat-absorber plate, said liquid cooled tube having two distal ends respectively terminated in an inlet and an outlet.    
   
   
       7 . The heat absorber structure as claimed in  claim 6 , wherein said liquid cooled tube has a flat shape in section.  
   
   
       8 . The heat absorber structure as claimed in  claim 6 , wherein said heat-absorber plate is a copper plate.  
   
   
       9 . The heat absorber structure as claimed in  claim 6 , wherein said liquid cooled tube is a copper tube.  
   
   
       10 . The heat absorber structure as claimed in  claim 6 , wherein said liquid cooled tube is welded to the top surface of said heat-absorber plate with a weld rod of P/Cu.
