Heat exchanger

Abstract

The invention relates to a plate heat exchanger ( 9 ) with a plurality of heat exchanger plates ( 1, 13 ), each 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. The heat exchanger ( 9 ) has a first type of indentations ( 2, 14 ) and a second type of indentations ( 3, 15 ), wherein the number of said first type of indentations ( 2, 14 ) and said second type of indentations ( 3, 15 ) are differing.

         2 . The plate heat exchanger according to  claim 1 , wherein said first type of indentations and said second type of indentations are of a different design and/or of a different size. 
     
     
         3 . The plate heat exchanger according to  claim 1 , wherein said first type of indentations and said second type of indentations are of a different shape. 
     
     
         4 . The plate heat exchanger according to  claim 1 , wherein said first type of indentations and said second type of indentations show essentially the same shape. 
     
     
         5 . The plate heat exchanger according to  claim 1 , wherein at least said first type of indentations and/or at least said second type of indentations show at least partially an elliptical shape, a circular shape, a teardrop-like shape, a polygonal shape and/or a symmetric polygonal shape. 
     
     
         6 . The plate heat exchanger according to wherein the number and/or the arrangement of at least said first type of indentations and/or at least said second type of indentations corresponds to the shape of at least said first type of indentations and/or at least said second type of indentations. 
     
     
         7 . The plate heat exchanger according to  claim 1 , wherein at least said first type of indentations and/or at least said second type of indentations are designed, at least in part, with an essentially flat top and/or bottom surface area. 
     
     
         8 . The plate heat exchanger according to  claim 1 , wherein at least said first type of indentations and/or at least said second type of indentations are arranged, at least in part, along straight lines (A, B, C, D), wherein said lines (A, B, C, D) are preferably arranged with an angle relative to a side edge of the corresponding heat exchanger plate. 
     
     
         9 . The plate heat exchanger according to  claim 1 , wherein at least said first type of indentations and/or at least said second type of indentations are arranged, at least in part, in such a way, that at least sectionally at least one of the circulating fluids has to follow a curved fluid path. 
     
     
         10 . The plate heat exchanger according to  claim 1 , wherein at least said first type of indentations and/or at least said second type of indentations are arranged, at least in part, in such a way, that at least sectionally at least one straight conduit for at least one of the circulating fluids is formed. 
     
     
         11 . The plate heat exchanger according to  claim 1 , wherein at least said first type of indentations and/or at least said second type of indentations are arranged, at least in part, in such a way that at least sectionally at least one conduit for at least one of the circulating fluids is arranged in parallel to at least one of the side edges of the corresponding heat exchanger plate. 
     
     
         12 . The plate heat exchanger according to  claim 1 , wherein at least one of said heat exchanger plates is formed, at least partially, of a metal plate and/or a metal alloy plate, wherein said plate preferably comprises, at least sectionally, a coating made out of an adhesive material, preferably made out of a soldering material. 
     
     
         13 . A heat exchanger plate comprising at least one section showing indentations, intended to be placed against corresponding indentations of a heat exchanger plate of a corresponding design, wherein 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, wherein the number of said first type of indentations and said second type of indentations are differing. 
     
     
         14 . The plate heat exchanger according to  claim 9 , wherein at least said first type of indentations and/or at least said second type of indentations are arranged, at least in part, in such a way that at least sectionally at least one conduit for at least one of the circulating fluids is arranged in parallel to at least one of the side edges of the corresponding heat exchanger plate.
