Abstract

A collector tube for a heat exchanger, which may have at least one flat tube, may include at least one recess, through which a separator may be inserted into the collector tube in an insertion position. The separator may have a separating wall comprising a separating wall thickness, wherein a clearance fit may be present between the separating wall and the recess in response to the insertion of the separator. The separating wall may provide at least one elevation to attain an increase of the separating wall thickness in a subarea of the separator. In the insertion position of the separator, the at least one elevation may be arranged in an area of the recess. In the insertion position, a press fit may be present between the at least one elevation and the recess.
