The invention relates to a heat exchanger tube produced by bending a metal strip (), characterized in that said strip () has a thickness that can vary between at least one first thickness (e) and at least one second thickness (e) greater than said first thickness (e), and in that said tube has thinned first zones (Z1) and reinforced second zones (Z2) located at the points of greatest mechanical stress, said first zones (Z1) being formed by first portions (P1) of said strip of first thickness (e) and said reinforced second zones (Z2) being formed by second portions (P2) of said strip () of second thickness (e). The invention also relates to a heat exchanger comprising a core bundle of such tubes, and to a method of obtaining such a tube.

Heat exchanger tube, and corresponding heat exchanger production method

The present invention relates to a brazing method for a component () of an air-conditioning circuit comprising a fluid refrigerant receiver (), said receiver containing a desiccator () for said fluid refrigerant. Said method includes the steps consisting of: equipping said receiver () with confinement means () capable of insulating said desiccator () from said component (); assembling and brazing together said receiver () and said component (); releasing said confinement means (). The invention also relates to a fluid receiver intended in particular for implementing such a method, with application to the air conditioning of motor vehicles.
