Plate for a plate kind heat exchanger with asymmetrical corrugations

Abstract

A plate (2) for a plate kind heat exchanger (1) is disclosed. The plate (2) is provided with a plurality of corrugations (8), a cross-section of the plate (2) thereby defining a plurality of hills (9) and valleys (10) which define flow paths along surfaces of the plate (2). The hills (9) and/or the valleys (10) have a shape which is asymmetrical with respect to a center line (11, 12) intersecting a top point of the hill (9) and/or valley (10). A plate kind heat exchanger (1) having a plurality of such plates (2) arranged in a stacked configuration, where the hills (9) and valleys (10) formed in the plates (2) define flow paths between the plates (2) is also disclosed.

1 . A plate for a plate kind heat exchanger, the plate being provided with a plurality of corrugations, a cross section of the plate thereby defining a plurality of hills and valleys which define flow paths along surfaces of the plate, wherein the hills and/or the valleys have a shape which is asymmetrical with respect to a center line intersecting a top point of the hill and/or valley. 
     
     
         2 . The plate for a plate kind heat exchanger according to  claim 1 , wherein the hills as well as the valleys have an asymmetrical shape. 
     
     
         3 . The plate for a plate kind heat exchanger according to  claim 1 , wherein the cross section of the hills and/or valleys define different curvatures at opposing sides of the center line. 
     
     
         4 . The plate for a plate kind heat exchanger according to  claim 1 , wherein a distance along a surface of the plate between a top point of a hill and a top point of a first neighboring valley differs from a distance along the surface of the plate between the top point of the hill and a top point of a second neighboring valley. 
     
     
         5 . The plate for a plate kind heat exchanger according to  claim 1 , wherein the hills and valleys form a herring bone pattern on the plate. 
     
     
         6 . The plate for a plate kind heat exchanger according to  claim 1 , wherein the asymmetry of a given hill and/or valley varies along a direction in which the hill and/or valley extends. 
     
     
         7 . The plate for a plate kind heat exchanger according to  claim 6 , wherein the variation in asymmetry is periodic. 
     
     
         8 . The plate kind heat exchanger comprising a plurality of plates according to  claim 1  arranged in a stacked configuration, wherein the hills and valleys formed in the plates define flow paths between the plates.
