ABSTRACT:
A header for a flat tube liquefier is composed of first and second components. The first component is provided in a tube bottom with receiving slots for the flat tubes and the second component complements the header structure, with the two components following one another in two overlap zones that extend along the length of the header and seal the two components against each other. A solder connection is provided in the respective overlap zone. If in these two overlap zones the first component is arranged to lie on the outside and the second component on the inside, the first component grips around the second component toward the interior and/or the second component is disposed completely within the outer width dimension of the first component. Moreover, beads may be formed in the tube bottom at both sides of the respective receiving slot at the side of the receiving slot that faces away from the curvature of the tube bottom. These beads end in the end region of the curvature of the tube bottom and are pressed against the respectively inserted flat tube in the direction of the curvature of the tube bottom while deforming the material of the periphery of the receiving slots.
