ABSTRACT OF THE DISCLOSURE A novel tubular heat exchanger is provided herein. The heat exchanger comprises a housing, at least one tube bundle disposed in the housing, each tube bundle containing a plurality of substantially parallel tubes, the opposite end portions and a substantially intermediate portion of the tubes being disposed in troughs containing a plurality of holes for receiving the tube end portions, the troughs containing a solidified casting resin which extends into the annular gaps between the holes and the tube end portions, a substantially horizontal flange being fixed to the inside of the housing, a lowermost trough resting on the flange and the tube bundle cooperating with the housing so that a gap is formed between the sidewalls of the troughs and the housing, the gap also contain- ing the casting resin. By this heat exchanger, any thermic stresse between the mounted tube bundles and the metallic housing surrounding the tube bundle or bundles are substantially avoided.
