Aluminium Automobile heat exchanger

Most of aluminum heat exchangers are brazed in controlled atmosphere brazing (CAB) furnaces,

using fluxes to remove the oxide layer on the brazing sheet surface. This study rather focuses on

plates and fins heat exchangers brazed under secondary vacuum. They consist of alternative 4004

(clad) / 3003 (core) brazing sheets and 3003 fins. The clad layer melts and flows when the brazing

temperature is reached (around 590°C), permitting the junction between the parts to be assembled.

Here, magnesium in the 4004 alloy plays the role of the flux [1]. A certain amount of it evaporates

above 400°C which disrupts the oxide layer and acts as a getter to prevent from re-oxidation during brazing.

*Excellent collapse resistance and strength after brazing 

*Good mechanical property and surface condition 

*Various specifications for soldering sheet
