Stacked plate for a stacked-plate heat exchanger and associated stacked-plate heat exchanger

Abstract

The present disclosure concerns a stacked plate for a stacked-plate heat exchanger, e.g., for a motor vehicle. The stacked plate includes an inlet, an outlet, and a U-shaped flow path extending between the inlet and the outlet. A raised separating web is disposed along a longitudinal centre of the stacked plate, and extends between the inlet and the outlet and provide a U-shaped extent of the U-shaped flow path. The separating web includes at least one U-shaped protrusion and at least one separating web portion projecting from the separating web.

         6 . The stacked plate according to  claim 1 , wherein the raised separating web extends from an edge of a short side between the inlet and the outlet over a maximum of 80% of a length of the stacked plate. 
     
     
         7 . The stacked plate according to  claim 1 , wherein the stacked plate is an aluminium plate or sheet metal. 
     
     
         8 . A stacked-plate heat exchanger, comprising: at least two stacked plates, the at least two stacked plates respectively including:
 an inlet, an outlet, and a U-shaped flow path extending between the inlet and the outlet;   a raised separating web disposed along a longitudinal centre of the respective stacked plates, the raised separating web structured and arranged to extend between the inlet and the outlet and provide a U-shaped extent of the U-shaped flow path;   wherein the raised separating web includes at least one U-shaped protrusion and at least one separating web portion projecting therefrom; and   wherein the at least two stacked plates are alternatingly arranged twisted by 180° about a vertical axis on top of one another and are soldered to one another with a continuous soldering seam provided in a region of the separating web.   
     
     
         9 . The stacked-plate heat exchanger according to  claim 8 , wherein the at least one separating web portion of one of the at least two stacked plates is soldered to a non-raised centre portion of the at least one U-shaped protrusion of another one of the at least two stacked plates. 
     
     
         10 . The stacked-plate heat exchanger according to  claim 8 , wherein the at least one U-shaped protrusion of one of the at least two stacked plates is soldered to a non-raised surrounding region of the at least one separating web portion of another one of the at least two stacked plates. 
     
     
         11 . The stacked-plate heat exchanger according to  claim 8 , wherein at least one of the at least two stacked plates further includes a plurality of raised flow guiding contours disposed along the U-shaped flow path. 
     
     
         12 . The stacked-plate heat exchanger according to  claim 11 , wherein at least one of the plurality of raised flow guiding contours comprises a bead. 
     
     
         13 . The stacked-plate heat exchanger according to  claim 8 , wherein the raised separating web of at least one of the at least two stacked plates includes at least two U-shaped protrusions and at least two separating web portions projecting therefrom.
