A method for the production of a tubular heat exchanger which comprises introducing the end portions of a plurality of tubes into a corresponding plurality of holes provided in troughs, substantially filling said troughs with a liquid casting resin whereupon the liquid casting resin enters the annular gaps between the holes and the tube end portions due to capillary action, to form, upon solidification of the casting resin, a tube bundle, inserting at least one tube bundle into a housing to form a tubular heat exchanger, the sidewalls of the troughs of the tube bundle forming a gap with the housing, and filling said gap with the casting resin.
