Heat exchanger

Abstract

The invention relates to a plate heat exchanger ( 9 ), comprising a plurality of heat exchanger plates ( 1, 13 ), comprising at least one section showing indentations ( 2, 3, 14, 15 ), intended to be placed against corresponding indentations ( 2, 3, 14, 15 ) of a heat exchanger plate ( 1, 13 ) of a corresponding design. At least a first type of indentations ( 2, 14 ) and at least a second type of indentations ( 3, 15 ) is provided, wherein said first type of indentations ( 2, 14 ) and said second type of indentations ( 3, 15 ) are of a different design.

1 . A plate heat exchanger, comprising at least one heat exchanger plate, wherein at least one of said exchanger plates comprises at least one section including indentations configured to be placed against corresponding indentations of a heat exchanger plate of a corresponding design, wherein the indentations include at least a first type of indentations and at least a second type of indentations, wherein said first type of indentations and said second type of indentations are of a different design. 
     
     
         2 . The plate type heat exchanger according to  claim 1 , wherein said first type of indentations and said second type of indentations are of a different size. 
     
     
         3 . The plate type heat exchanger according to  claim 1 , wherein said first type of indentations and said second type of indentations include essentially the same shape. 
     
     
         4 . The plate type heat exchanger according to  claim 2 , wherein said first type of indentations and said second type of indentations include essentially the same shape. 
     
     
         5 . The plate type heat exchanger according to  claim 1 , wherein said first type of indentations and said second type of indentations are of a different shape. 
     
     
         6 . The plate type heat exchanger according to  claim 1 , wherein the number of said first type of indentations and said second type of indentations are different. 
     
     
         7 . The plate type heat exchanger according to  claim 5 , wherein the number of said first type of indentations and said second type of indentations are different.
