Heat exchanger

Abstract

Disclosed is a heat exchanger which reduces a flow loss of air and increases a heat exchange performance by preventing condensate water from staying at surfaces of fins. To this end, the heat exchanger comprises: a plurality of tubes arranged with a predetermined interval so as to pass a fluid for the heat exchange; and fins mounted among the tubes for expanding a contact area with air, wherein the fins are tilted with a predetermined angle so as to prevent condensate water from staying at the surfaces of the fins.

What is claimed is:  
     
         1 . A heat exchanger comprising: 
 a plurality of tubes arranged with a predetermined interval so as to pass a fluid for heat exchange; and    fins respectively mounted among the tubes for expanding a contact area with air,    wherein the fins are tilted with a predetermined angle so as to prevent condensate water from staying at surfaces of the fins.    
     
     
         2 . The heat exchanger of  claim 1 , wherein the fins include plate portions attached to one side of the tubes with a predetermined interval; and louvers protruded at upper surfaces of the plate portions with a predetermined width, in which the louvers are formed to have a predetermined tilt angle.  
     
     
         3 . The heat exchanger of  claim 2 , wherein the louvers are formed to have a predetermined tilt angle on the basis of their width direction.  
     
     
         4 . The heat exchanger of  claim 2 , wherein the louvers are formed to have a predetermined tilt angle towards a downward direction along a direction which air flows.  
     
     
         5 . The heat exchanger of  claim 1 , wherein the fins include plate portions attached to one side of the tubes with a predetermined interval; and louvers protruded at the upper surfaces of the plate portions with a predetermined width, in which the plate portions are formed to have a predetermined tilt angle.  
     
     
         6 . The heat exchanger of  claim 5 , wherein the plate portions are formed to have a predetermined tilt angle on the basis of their width direction.  
     
     
         7 . The heat exchanger of  claim 5 , wherein the plate portions are formed to have a predetermined tilt angle towards a downward direction along a direction which the air flows.  
     
     
         8 . The heat exchanger of  claim 1 , wherein the fins include plate portions attached to one side of the tube with a predetermined interval; and louvers protruded at the upper surfaces of the plate portions with a predetermined width, in which the plate portions and the louvers are formed to have predetermined tilt angles on the basis of their width directions, respectively.  
     
     
         9 . The heat exchanger of  claim 8 , wherein the plate portions and the louvers are formed to have predetermined tilt angles on the basis of their width directions.  
     
     
         10 . The heat exchanger of  claim 8 , wherein the plate portions and the louvers are formed to respectively have predetermined tilt angles towards a downward direction along a direction which the air flows.
