Heat Exchanger, in Particular a Charge Intercooler or Coolant Cooler for Motor Vehicles

Abstract

The invention relates to a heat exchanger ( 1 ), in particular a charge intercooler or coolant cooler for motor vehicles, which comprises a soldered block which is made of pipes ( 4 ), ribs and at least one pipe base ( 2 ), in addition to at least one plastic box ( 3 ) which has a wall ( 3 a ) which extends in the cross-section and which is approximately U shaped and a surrounding flange ( 3 b ). The box is mechanically connected to the pipe base over flange ( 3 b ). According to the disclosure, reinforcing ribs are arranged on the inner side of the plastic box ( 3 ) in a transition area between the flange ( 3 b ) and the wall ( 3 a ).

       11 . A heat exchanger, particularly a charge intercooler or coolant cooler for motor vehicles, with a specially soldered block consisting of pipes ( 4 ), ribs and at least one pipe base ( 2 ), as well as at least one box ( 3 ), particularly one made of plastic or metal, which has a wall ( 3   a ), particularly one with an approximately U-shaped cross section, and a circumferential flange ( 3   b ), and which is connected mechanically via the flange ( 3   b ) to the pipe base ( 2 ), characterized in that, on the internal side of the box ( 3 ), particularly in a transitional area ( 5 ), reinforcing ribs ( 6 ) are arranged between the flange ( 3   b ) and the wall ( 3   a ).  
   
   
       12 . The heat exchanger according to  claim 11 , characterized in that the transitional area has an offset ( 5 ) which is directed inward and in particular is peripheral.  
   
   
       13 . The heat exchanger according to  claim 11 , characterized in that the reinforcing ribs ( 6 ) have inner edges ( 6   a ) that are designed to be in alignment with the internal wall ( 3   d ).  
   
   
       14 . The heat exchanger according to  claim 11 , characterized in that the pipes are designed as round, oval or flat pipes ( 4 ), arranged in one or more rows, and received in the at least one pipe base ( 2 ), and in that the reinforcing ribs ( 6 ) are arranged on the walls ( 3   a ) of the plastic box ( 3 ) with separations that correspond to the pipe spacing or to an external rib spacing.  
   
   
       15 . The heat exchanger according to  claim 14 , characterized in that the reinforcing ribs ( 6 ) are arranged in each case at the height of the pipes ( 4 ).  
   
   
       16 . The heat exchanger according to  claim 14 , characterized in that the reinforcing ribs ( 6 ) are arranged in each case between the pipes ( 4 ).  
   
   
       17 . The heat exchanger according to  claim 11 , characterized in that a transitional area ( 9 ) is included as part of te construction, said transitional area ( 9 ) having a wavy design and exhibits recesses ( 10 ) as well as bulges ( 11 ) on the interior side, and recessed areas on the external side of the plastic box ( 7 ,  13 ) in which parts of the pipe base engage with positive locking.  
   
   
       18 . The heat exchanger according to  claim 17 , characterized in that reinforcement ribs ( 8 ) are arranged above the recesses ( 10 ).  
   
   
       19 . The heat exchanger according to  claim 17 , characterized in that other reinforcing ribs ( 12 ) are arranged in the area of the bulges ( 11 ) and between the recesses ( 10 ).  
   
   
       20 . The heat exchanger according to  claim 11 , characterized in that the reinforcing ribs ( 6 ) have rib surfaces that are arranged parallel to the direction of removal of the box ( 3 ) from a mold.  
   
   
       21 . The heat exchanger according to  claim 17 , characterized in that the reinforcement ribs ( 8 ) have rib surfaces that are arranged parallel to the direction of removal of the box ( 7 ) from a mold.  
   
   
       22 . The heat exchanger according to  claim 19 , characterized in that the other reinforcing ribs ( 12 ) have rib surfaces that are arranged parallel to the direction of removal of the box ( 13 ) from a mold.
