Abstract: A tube bundle heat exchanger having a tube sheet, an outer shell and an interior. The heat exchanger includes a tube bundle having tubes located in the interior for fluid flow. The tubes have outside ribs and a channel is formed between adjacent ribs. The tube sheet has openings as passage points. Outer fins of the tubes project into the openings, and a joint gap is formed between an inner surface defining the opening and the outer fins of a tube located therein. The tubes are bonded to the tube sheet by joining material with the involvement of the outer fins. The bond is only formed in a first portion of the opening. The first portion is filled with joining material such that a second portion of the opening remains which is not filled with joining material, and the tube has outer fins adjacent the second portion.
