Heat-exchange type cooler

Abstract

A heat-exchange type cooler includes a top panel, a bottom panel, radiation fins arranged in parallel between the top panel and the bottom panel, heat exchange tubes vertically inserted through the top and bottom panels and the radiation fins, a top cover and a bottom cover respectively covered on the top panel and the bottom panel and defining with the top panel and the bottom panel a top chamber and a bottom chamber, and partition plates respectively mounted inside the top and bottom chambers and dividing the top and bottom chambers into top sub-chambers and bottom sub-chambers that form with the heat exchange tubes a detoured one-way fluid passage for guiding a heat exchange fluid in one direction in a roundabout way.

1 . A heat-exchange type cooler comprising: 
 a plurality of radiation fins arranged in parallel and vertically spaced from one another at a predetermined pitch, said radiation fins each having a plurality of vertical through holes;    a plurality of heat exchange tubes respectively vertically mounted in the vertical through holes of said radiation fins, said heat exchange tubes each having a top end and a bottom end respectively protruding over top and bottom sides of said radiation fins;    a top panel arranged in parallel to said radiation fins at a top side, said top panel having a plurality of through holes respectively coupled to the top end of each of said heat-exchange tubes and sealed to the outside periphery of each of said heat-exchange tubes;    a bottom panel arranged in parallel to said radiation fins at a bottom side, said bottom panel having a plurality of through holes respectively coupled to the bottom end of each of said heat-exchange tubes and sealed to the outside periphery of each of said heat-exchange tubes;    a top cover covered on a top side of said top panel and defining with said top panel a watertight top chamber; and    a bottom cover covered on a bottom side of said bottom panel and defining with said bottom panel a watertight bottom chamber;    wherein partition plates are respectively mounted inside said top chamber and said bottom chamber, dividing said top chamber into a plurality of top sub-chambers and dividing said bottom chamber into a plurality of bottom sub-chambers;    wherein the top and bottom ends of each of said heat exchange tubes are respectively disposed in fluid communication with at least one of said top sub-chambers and at least one of said bottom sub-chambers such that said heat exchange tubes and said top sub-chambers and said bottom sub-chambers form a detoured one-way fluid passage for guiding a heat exchange fluid in one direction in a roundabout way.    
   
   
       2 . The heat-exchange type cooler as claimed in  claim 1 , wherein said bottom cover has a water inlet in fluid communication with one of said bottom sub-chambers in a first end of said detoured one-way fluid passage.  
   
   
       3 . The heat-exchange type cooler as claimed in  claim 1 , wherein said bottom cover has a water outlet in fluid communication with one of said bottom sub-chambers in a last end of said detoured one-way fluid passage.  
   
   
       4 . The heat-exchange type cooler as claimed in  claim 1 , wherein said heat exchange tubes each have a top shoulder disposed around the top end thereof and stopped at the top side of said top panel.  
   
   
       5 . The heat-exchange type cooler as claimed in  claim 1 , wherein said heat exchange tubes each have a bottom shoulder disposed around the bottom end thereof and stopped at the bottom side of said bottom panel.  
   
   
       6 . The heat-exchange type cooler as claimed in  claim 1 , further comprising a fan fastened to said radiation fins at one lateral side.
