Heat exchanger plate with fluid flow disrupting elements

Abstract

The present invention relates to a plate of a heat exchanger having two opposite longitudinal edges connected to one another by two lateral edges, these longitudinal edges and lateral edges surrounding a bottom wall, an angle measured between this bottom wall and any one of the edges ranging between 103.5° and 109.5°, a thickness of the plate ranging between 0.20 mm and 0.45 mm, the bottom wall being equipped with fluid-flow-disturbing elements, these fluid-flow-disturbing elements having a vertical dimension that ranges between 0.75 mm and 1.15 mm.

What is claimed is: 
     
         1 . A plate for a heat exchanger having a tub-like form with two opposite longitudinal edges connected to one another by two lateral edges, these longitudinal edges and lateral edges surrounding a bottom wall of the plate, an angle measured between this bottom wall and any one of the edges ranging between 103.5° and 109.5°, a thickness of the bottom wall ranging between 0.20 mm and 0.45 mm, the bottom wall being equipped with fluid-flow-disturbing elements, at least one of these fluid-flow-disturbing elements having a vertical dimension measured inside a volume delimited by the bottom wall and the edges that ranges between 0.75 mm and 1.15 mm. 
     
     
         2 . The plate as claimed in  claim 1 , wherein the vertical dimension of the fluid-flow-disturbing elements is a first vertical dimension ranging between 0.75 mm and 0.85 mm. 
     
     
         3 . The plate as claimed in  claim 1 , wherein the vertical dimension of the fluid-flow-disturbing elements is a second vertical dimension ranging between 1.05 mm and 1.15 mm. 
     
     
         4 . The plate as claimed in  claim 1 , wherein the bottom wall is equipped with at least four fluid distribution openings, with each of the at least four fluid distribution openings being disposed in the vicinity of a junction between a longitudinal edge and a lateral edge. 
     
     
         5 . The plate as claimed in  claim 1 , wherein the fluid-flow-disturbing elements include at least one truncated dome extending between a base and a top. 
     
     
         6 . The plate as claimed in  claim 5 , wherein a maximum diameter of the at least one truncated dome measured at its base is 4.5 mm. 
     
     
         7 . The plate as claimed in  claim 5 , wherein a minimum diameter of the at least one truncated dome measured at its top is 2 mm. 
     
     
         8 . A heat exchanger configured to bring about an exchange of heat between a first fluid and a second fluid, comprising plates having a tub-like form with two opposite longitudinal edges connected to one another by two lateral edges, these longitudinal edges and lateral edges surrounding a bottom wall of the plates, an angle measured between this bottom wall and any one of the edges ranging between 103.5° and 109.5°, a thickness of the bottom wall ranging between 0.20 mm and 0.45 mm, the bottom wall being equipped with fluid-flow-disturbing elements, at least one of these fluid-flow-disturbing elements having a vertical dimension measured inside a volume delimited by the bottom wall and the edges that ranges between 0.75 mm and 1.15 mm. 
     
     
         9 . The heat exchanger as claimed in  claim 8 , wherein the angle measured between the bottom wall and any one of the edges ranges between 105° and 108°. 
     
     
         10 . The heat exchanger as claimed in  claim 9 , wherein the fluid-flow-disturbing elements include at least one truncated dome extending between a base and a top, wherein the tops of the fluid-flow-disturbing elements of the plates are in contact with the bottom wall of the plates adjacent to it in the stacking direction.
