Method For Producing A Heat Exchanger

Abstract

The invention relates to a method of manufacturing a heat exchanger ( 10 ) for an air heating apparatus ( 12 ) for integration into a housing which guides air. The heat exchanger has a heat exchanger body ( 14 ) with a longitudinal axis. According to the invention, the heat exchanger body ( 14 ) is at least partially fabricated in a pressure-casting process employing two molded masses (“cores”), with the molded masses being withdrawn from the mold in opposite directions ( 40, 42 ) extending along the longitudinal axis.

1 . A method of manufacturing a heat exchanger ( 10 ) for an air heating apparatus ( 12 ) for integration into an air-guiding housing, which heat exchanger has a heat exchanger body ( 14 ) with a longitudinal axis; characterized in that the heat exchanger body ( 14 ) is at least partially fabricated in a pressure-casting process employing two molded masses, with the molded masses being withdrawn from the mold in opposite directions ( 40 ,  42 ) extending along the longitudinal axis. 
   
   
       2 . A method according to  claim 1 ; characterized in that the heat exchanger core ( 20 ) has an interior profile ( 30 ). 
   
   
       3 . A method according to  claim 2 ; characterized in that the interior profile has vanes or the like which extend in the longitudinal direction. 
   
   
       4 . A method according to one of the preceding claims; characterized in that the heat exchanger body ( 14 ), a heat exchanger base ( 16 ), and a heat exchanger head are fabricated separately.
