Heat exchanger

Abstract

A heat exchanger includes a header, a tank and a gasket between the header and the tank. The gasket at least includes one portion protruding from the header, which is in sealing engagement with a portion of the tank. In some embodiments, the portion protruding from the header may include a V-shaped or U-shaped groove that is open to the portion of the tank.

         13 . A heat exchanger comprising:
 a header);   a tank; and   a gasket disposed between the header and the tank, wherein the gasket further comprises at least one protruding portion protruding from the header, which is in sealing engagement with a portion of the tank.   
     
     
         14 . The heat exchanger according to  claim 13 , wherein the protruding portion further comprises a V-shaped groove or U-shaped groove that is open to the portion of the tank. 
     
     
         15 . The heat exchanger according to  claim 13 , wherein the header is curved in a direction of the tank. 
     
     
         16 . The heat exchanger according to  claim 13 , wherein the header further comprises at least one rib or a bead between openings for tubes. 
     
     
         17 . The heat exchanger according to  claim 16 , wherein the at least one rib or the bead is formed in its course corresponding to the protruding portion. 
     
     
         18 . The heat exchanger according to  claim 13 , wherein the header has rows of openings, a width of which measured perpendicular to a direction of the rows varies along the direction of the rows. 
     
     
         19 . The heat exchanger according to  claim 13 , wherein the header further comprises at least one opening configured to receive two or more tubes. 
     
     
         20 . The heat exchanger according to  claim 13 , wherein the header further comprises at least one opening, an edge of which protrudes from a plane of the opening. 
     
     
         21 . The heat exchanger according to  claim 13 , wherein the header and the tank are connected by means of at least one clip. 
     
     
         22 . The heat exchanger according to  claim 21 , wherein the header and/or the tank and/or the gasket further comprises an opening for the clip. 
     
     
         23 . The heat exchanger according to  claim 21 , wherein the clip is provided on the header or the tank. 
     
     
         24 . The heat exchanger according to  claim 21 , wherein the clip or a locking projection interacting with the clip is provided on a separate member that is inserted into the header.
