Heat Exchanger Plate

Abstract

The present invention relates to a flat tube plate ( 2 ) for an heat exchanger ( 1 ) made from a stamped metal sheet with an peripheral edge ( 30 ) contained within a plane zone (P) and forming a joining area ( 42 ). The plate ( 4 ) includes at least one wall ( 40 ) extending perpendicular to the plane zone (P).

1 . A plate ( 4 ) for a flat tube ( 2 ) of a heat exchanger ( 1 ) made of chased sheet metal comprising a peripheral edge ( 30 ) contained in a plane (P) and forming a connection area ( 42 ), characterized in that the plate ( 4 ) includes at least one wall ( 40 ) extending perpendicularly to the plane (P) containing the peripheral edge ( 30 ). 
   
   
       2 . A plate ( 4 ) according to  claim 1 , characterized in that the plate ( 4 ) comprises a first and a second large side ( 26 ) and a first and a second small side ( 28 ), and the wall ( 40 ) is arranged on at least a portion of the first large side ( 26 ). 
   
   
       3 . A plate ( 4 ) according to  claim 2 , characterized in that the wall ( 40 ) is arranged over the entire length of the first large side ( 26 ). 
   
   
       4 . A plate ( 4 ) according to  claim 2 , characterized in that the wall ( 4 ) is arranged on at least a portion of the first and/or second small side(s) ( 28 ). 
   
   
       5 . A plate ( 4 ) according to  claim 1 , characterized in that the plate ( 4 ) has a plane of symmetry perpendicular to the large sides ( 26 ). 
   
   
       6 . A plate ( 4 ) according to  claim 1 , characterized in that the chased sheet metal has a thickness (th) below or equal to 0.35 mm. 
   
   
       7 . A plate ( 4 ) according to  claim 1 , characterized in that the chased sheet metal comprises at least one lug ( 200 ) and at least one notch ( 210 ) arranged on the peripheral edge ( 30 ) of the flat tube ( 4 ). 
   
   
       8 . A flat tube ( 2 ) for a heat exchanger ( 1 ), characterized in that the flat tube ( 2 ) comprises at least one first plate ( 4 ) according to  claim 1 . 
   
   
       9 . A flat tube ( 2 ) for a heat exchanger ( 1 ), characterized in that the flat tube ( 2 ) comprises a first and a second plate ( 4 ) according to  claim 1 . 
   
   
       10 . A flat tube ( 2 ) for a heat exchanger ( 1 ) according to  claim 9 , characterized in that the first and the second plates ( 4 ) are arranged so that the first large side ( 26 ) of the first plate ( 4 ) cooperates with the second large side ( 26 ) of the second plate ( 4 ). 
   
   
       11 . A heat exchanger ( 1 ) including at least one flat tube ( 2 ) according to  claim 8 . 
   
   
       12 . A plate according to  claim 3 , characterized in that the wall ( 4 ) is arranged on at least a portion of the first and/or second small side(s) ( 28 ).
