A flat heat exchanger tube formed of a single strip of rolled aluminum, with at least one connection between the two broad sides. The connection is generally parallel to and spaced between the narrow sides and divides the heat exchanger tube into at least two chambers, and includes two legs consisting of bent opposite edges of the aluminum strip, the legs each having a head at adjacent bends along one of the broad sides and feet adjacent the other broad side. The legs lie against each other generally at their head over no more than half of the entire spacing between the two broad sides, with the legs enclosing an angle between them of about 20° to 100° or about 45° to 75°, advantageously 60°.
