Abstract

Heat exchanger having a tube plate made of plastic, in which metallic tubes are fixed. The tube plate has elevations having openings for accommodating the tube ends, with the openings being subdivided into three sections in axial extension. The center section has the smallest cross-section and the end sections are in each case widened. The elevations extend on both sides of the tube plate, the total height of the elevations located in the area of an opening, inclusive of the tube plate thickness, being about 1.8 to 2.5 times the single tube plate thickness.
