Fluid passage arrangement of a heat absorber for use in a liquid-cooling type cooling apparatus

Abstract

A fluid passage arrangement of a heat absorber for use in a liquid-cooling type cooling apparatus is disclosed to have a heat-absorber plate, and a cover plate covering the heat-absorber plate and defining with the heat-absorber plate a hermetically sealed chamber, the heat-absorber plate having upright partition strips that divide the sealed chamber into multiple partition zones that form a maze passage and are respectively divided into parallel passages by parallel fins. The partition strips and parallel fins lower the flowing speed of the heat-transfer fluid passing through the heat absorber and increase the contact area between the heat-transfer fluid and the heat absorber, increasing the heat energy absorbing effect of the heat absorber and the utilization of the cooling apparatus.

1 . A fluid passage arrangement of a heat absorber for use in a liquid-cooling type cooling apparatus, comprising a heat-absorber plate, and a cover plate covering said heat-absorber plate and defining with said heat-absorber plate a hermetically sealed chamber, said cover plate having two through holes in communication between said sealed chamber and the outside space, wherein: 
 said sealed chamber comprises at least one partition strip, said at least one partition strip dividing said sealed chamber into at least two partition zones, and a plurality of parallel fins arranged in parallel in each of said at least two partition zones and defining in each of said at least two partition zones a plurality of parallel passages, each of two adjacent ones of said at least two partition zones having one same side connected to each other to form a maze passage, said maze passage having a front and a rear end respectively connected to the through holes of said cover plate.    
   
   
       2 . The fluid passage arrangement as claimed in  claim 1 , wherein said heat-absorber plate has a top face; said at least one partition strip is upwardly protruded from said top face of said heat-absorber plate.  
   
   
       3 . The fluid passage arrangement as claimed in  claim 2 , wherein said parallel fins are upwardly protruded from the top face of said heat-absorber plate.  
   
   
       4 . The fluid passage arrangement as claimed in  claim 1 , therein said heat-absorber plate further comprises a bottom flange downwardly protruded from a bottom face thereof, forming a heat absorbing zone attachable to a heat generating electronic device for absorbing heat energy.  
   
   
       5 . The fluid passage arrangement as claimed in  claim 1 , wherein said heat-absorber plate is a copper plate member.
