Abstract (en)
[origin: WO2012131038A1] The invention relates to a heat exchanger tube produced by folding a metal strip (11), characterized in that said strip (11) has a thickness that varies between at least one first thickness (e 1 ) and at least one second thickness (e 2 ) that is greater than said first thickness (e 1 ), and in that said tube has first thinner areas (Z1) and second reinforced areas (Z2) located at locations at which a high mechanical load is applied, said first areas (Z1) consisting of first portions (P1) of said strip having a first thickness (e 1 ) and said reinforced second areas (Z2) consisting of second portions (P2) of said strip (11) having a second thickness (e 2 ). The invention also relates to a heat exchanger including a bundle of such tubes, as well as to a method for producing such a tube.
