Heat exchanger and turbulator for the same

Abstract

Disclosed are a heat exchanger and a turbulator for the same. The heat exchanger is integrally manufactured in a novel structure with a desirable size, so that the productivity can be improved and the flow resistance of the fluid can be minimized. The turbulator for a heat exchanger includes a plurality of crests and a plurality of valleys that are repeatedly formed, and a plurality of bent ends formed on front and rear surfaces of each crest and inwardly bent while being repeatedly alternated in a direction along which the crest and the valley are repeatedly formed. A portion of each bent end is inclined left or right to form a through hole perforated in the direction along which the crest and the valley are repeatedly formed so that the fluid passes through the through hole.

1 . A heat exchanger comprising:
 a plurality of heat exchange plates stacked on each other while being spaced apart from each other; and   a turbulator interposed between the heat exchange plates, the turbulator having a plurality of crests and a plurality of valleys, which are repeatedly formed along a flow direction of a fluid while being integrally provided with each other, each crest having a plurality of bent ends, which are formed on each crest and bent inwardly while being repeatedly alternated, and the tabulator having a through hole defined by the bent ends in a direction along which the crest and the valley are repeatedly formed, so that the fluid passes through the through hole.   
     
     
         2 . The heat exchanger of  claim 1 , wherein the bent ends formed on the each crest of the turbulator are inwardly bent in a state that the bent ends are inclined in the flow direction of the fluid, and the through hole to allow the fluid to flow therethrough is defined by the bent ends. 
     
     
         3 . The heat exchanger of  claim 2 , wherein each bent end is inclined at an angle in a range of 20° to 45°. 
     
     
         4 . A turbulator for a heat exchanger, the turbulator comprising:
 a plurality of crests and a plurality of valleys that are repeatedly formed; and   a plurality of bent ends formed on front and rear surfaces of each crest and inwardly bent while being repeatedly alternated in a direction along which the crest and the valley are repeatedly formed,   wherein a portion of each bent end is inclined left or right to form a through hole perforated in the direction along which the crest and the valley are repeatedly formed so that the fluid passes through the through hole.   
     
     
         5 . The turbulator of  claim 4 , wherein each bent end is inclined at an angle in a range of 20° to 45°. 
     
     
         6 . The turbulator of  claim 4 , wherein the bent ends formed on each crest are inclined in symmetry to each other in a direction along which each crest is repeatedly formed, and the direction is a flow direction of the fluid. 
     
     
         7 . The turbulator of  claim 4 , wherein, when viewed in the direction serving a flow direction of a fluid along which the crest and the valley are repeatedly formed, the bent ends provided at the left sides are inclined in symmetry to the bent ends provided at the right sides. 
     
     
         8 . The turbulator of  claim 4 , wherein the crests and the valleys are inclined about an introduction direction of a flow which is a flow direction of the fluid. 
     
     
         9 . The turbulator of  claim 8 , wherein the crests and the valleys are inclined at an angle in a range of 10° to 30°, and each bent end is inclined at an angle in a range of about 20° to 45°.
