## Abstract

A tubing element for a heat exchanger is at least partially a rigid elongated tubing having a first end, a second end, a first side wall and a second side wall. First and second side walls are substantially parallel to each other. The distance between first side wall and second side wall is considerably smaller than the width of first side wall and second side wall, resulting in a substantially overall flat tubing structure with connection walls on both sides. The tubing element has a plurality of fins on at least one of the outer surfaces of the first side wall and/or of the second side wall. Fins define an angle enclosed by the fins and a connection wall. A heat exchanger, use of a tubing element, use of a heat exchanger and method of manufacturing of a tubing element to manufacture at least partially a heat exchanger are included.
