Heat exchanger unit, in particular for a motor vehicle and method for producing said unit

Abstract

The invention relates to a heat exchanger unit comprising tubes, ribs and a lateral section containing reinforcement ribs, in addition to a method for producing said unit.

1 . A heat exchanger unit, in particular for a motor vehicle, comprising at least one heat exchanger, having tubes and heat-transfer fins, and having at least one side part, which comprises a baseplate and at least one reinforcing fin, characterized in that at least one reinforcing fin is formed by a deformed center piece of the surface of the baseplate.  
   
   
       2 . The heat exchanger unit as claimed in  claim 1 , characterized in that at least one reinforcing fin runs in a longitudinal direction of the side part.  
   
   
       3 . The heat exchanger unit as claimed in  claim 1 , characterized in that at least one reinforcing fin runs in a transverse direction of the side part.  
   
   
       4 . The heat exchanger unit as claimed in  claim 1 , characterized in that at least one reinforcing fin runs at an angle α, where 0°<α<90°, with respect to a longitudinal direction of the side part.  
   
   
       5 . The heat exchanger unit as claimed in to  claim 1 , characterized in that at least one reinforcing fin is provided with at least one securing means.  
   
   
       6 . The heat exchanger unit as claimed in  claim 5 , characterized in that the at least one securing means is formed by an at least partially deformed reinforcing fin.  
   
   
       7 . The heat exchanger unit as claimed in  claim 1 , characterized in that the side part has at least one expansion section, which is formed by one or more apertures, in particular aligned with one another, and a plurality of webs adjoining the apertures, at least one aperture corresponding to a center piece of the surface of the baseplate which has been deformed to form a reinforcing fin.  
   
   
       8 . The heat exchanger unit as claimed in  claim 7 , characterized in that the webs have fold-like beads.  
   
   
       9 . A process for producing a side part for a heat exchanger unit comprising at least one heat exchanger, characterized by the process steps of a) providing an areal metal sheet having a width b which is substantially equal to a width of the side part, b) precutting sections of an edge of at least one piece of the surface of the metal sheet, and c) deforming the at least one piece of the surface out of a plane which is predetermined by the areal metal sheet, to form at least one reinforcing fin.
