Abstract
A tube for a heat exchanger defining a fluid circulation channel is disclosed. The channel extends along a longitudinal direction and includes a first flat wall including at least one pair of disturbance elements. The pair of disturbance elements is formed by a first and second disturbance element. The first and second disturbance elements are formed by a local deformation of the first flat wall toward the inside of the tube. The first and second disturbance elements extend between a first base and a first crest and between a second base and a second crest respectively. The first crest has an elongate shape along a first straight line and the second crest has an elongate shape along a second straight line. The first straight line intersects the second crest. The first and second crests have the same length measured between the two free ends of the crests.
