Heat exchanger

Abstract

A heat exchanger is provided. The heat exchanger includes a tube through which a refrigerant flows, a fin disposed on an outer periphery of the tube, and an agitating member inserted into the tube, and agitating the refrigerant.

1 . A heat exchanger comprising: 
 a tube through which a refrigerant flows;    a fin disposed on an outer periphery of the tube; and    an agitating member inserted into the tube, and agitating the refrigerant.    
   
   
       2 . The heat exchanger according to  claim 1 , wherein the agitating member has a helical shape.  
   
   
       3 . The heat exchanger according to  claim 1 , wherein the agitating member is disposed in a section where a liquid refrigerant flows.  
   
   
       4 . The heat exchanger according to  claim 1 , wherein a distance between pitches of the agitating member is greater than an inner diameter of the tube.  
   
   
       5 . The heat exchanger according to  claim 1 , wherein a plurality of protrusions are formed on an inner periphery of the tube.  
   
   
       6 . The heat exchanger according to  claim 1 , wherein the agitating member is provided in a linear section of the tube.  
   
   
       7 . A heat exchanger comprising: 
 a tube;    a fin contacting the tube to be thermally in contact with an external air; and    an agitating member spiraled a plurality of times for increasing a contact area between a liquid refrigerant and an inner periphery of the tube, the agitating member being provided inside the tube.    
   
   
       8 . The heat exchanger according to  claim 7 , wherein the agitating member is curved in a direction different from a flow direction of a refrigerant.  
   
   
       9 . The heat exchanger according to  claim 7 , wherein an outer diameter of the agitating member is 95% or less of an inner diameter of the tube.  
   
   
       10 . The heat exchanger according to  claim 7 , wherein an inner diameter of the agitating member is 25%˜40% of an inner diameter of the tube.  
   
   
       11 . The heat exchanger according to  claim 7 , wherein the agitating member is provided to an outlet of the tube when a refrigerant passing through a compressor flows into the tube.  
   
   
       12 . The heat exchanger according to  claim 7 , wherein the agitating member is provided to an inlet of the tube when the refrigerant undergoing an expansion procedure flows into the tube
