Charge Air Intercooler

Abstract

The invention relates to a charge air intercooler ( 1 ), in particular for a private car, in which charge air can be cooled by a coolant flowing through flow channels, whereby the flow channels for the coolant are formed from flat tubes ( 6 ).

1 . A charge air intercooler, in particular for a passenger vehicle, in which charge air can be cooled by a coolant flowing in flow channels, wherein the flow channels for the coolant are formed by flat tubes. 
   
   
       2 . The charge air intercooler as claimed in  claim 1 , wherein the flat tubes are arranged in at least one row. 
   
   
       3 . The charge air intercooler as claimed in  claim 1 , wherein two or more rows of flat tubes are provided one behind the other in the flow direction of the charge air. 
   
   
       4 . The charge air intercooler as claimed in  claim 1 , wherein at least two rows of flat tubes are provided, and flow can take place through these in crosscurrent operation or in cross-counter current operation in relation to the charge air which is to be cooled, and/or in that flow can take place through individual chambers of the flat tubes in crosscurrent operation. 
   
   
       5 . The charge air intercooler as claimed in  claim 1 , wherein the individual components of the charge air intercooler are soldered together. 
   
   
       6 . The charge air intercooler as claimed in  claim 1 , wherein turbulence inserts are arranged in the flat tubes. 
   
   
       7 . The charge air intercooler as claimed in  claim 1 , wherein the flat tubes terminate in at least one collector tank. 
   
   
       8 . The charge air intercooler as claimed in  claim 7 , wherein the collector tank has a base with openings which correspond to the external dimensions of the flat tubes, and the flat tubes are soldered thereto. 
   
   
       9 . The charge air intercooler as claimed in  claim 1 , wherein corrugated ribs are provided between the flat tubes. 
   
   
       10 . The charge air intercooler as claimed in  claim 1 , wherein the coolant is a liquid, in particular water. 
   
   
       11 . The charge air intercooler as claimed in  claim 1 , wherein the charge air intercooler is arranged in a compressor housing or an intake housing. 
   
   
       12 . The charge air intercooler as claimed in  claim 1 , further comprising at least one air tank for guiding the charge air. 
   
   
       13 . The charge air intercooler as claimed in  claim 1 , wherein the ratio of charge air channel height (HL) to coolant channel height (HK) is 1:1 to 10:1, in particular 2:1 to 8:1.
