Abstract (en)
[origin: WO2010037803A1] The invention relates to a heat exchanger and to a method for making same. The exchanger comprises components essentially made of aluminium (Al). The components include a tube cluster, inserts disposed between and/or in the tubes of said cluster, and at least one collector plate. The method of the invention includes the steps of: selecting tubes made of an aluminium core alloy and comprising 0.3 and 3.0 wt % of magnesium (Mg) as well as other chemical elements; selecting the thickness of said tubes independently from the thickness of said spacers; coating at least one surface of at least some of said components with an aluminium filler alloy; and assembling said components by flux-free brazing in a controlled atmosphere at a temperature of between 580°C and 620°C.
