A heat exchanger 14, especially a heat exchanger in the form of a comfort heat exchanger. is disclosed. The heat exchanger 14 is comprised of two manifold elements 15.16 adapted to receive and discharge fluid, and a plurality of tube units 22 transverely located between the manifolds, each tube unit 22 being integrally connected to substantially rigid end elements 18 that fit into the manifolds 15,16. The tubes 19 are preferably oriented and expanded to about their original diameter. The heat exchanger 14 is intended to be fabricated from polymer, especially polyamide compositions. The tube units 22 are intended to be manufactured using injection moulding techniques, and then subjected to orientation and expansion steps. Parts fabricated during manufacture of the heat exchangers 14 are also disclosed. The heat exchangers 14 are particularly intended for use as comfort heat exchangers in automobiles. |
