Abstract

The joints between manifold tanks and arrays of tubes of a heat exchanger are sealed by applying a sealant locally around the end(s) of each tube. A pref. sealant comprises PVC deposited from a simple plastisol and subsequently gelled to a tough, elastic seal by thermal shock treatment at 140-200, pref. 160 degrees C. Alternative sealant is made by mixing epoxy resin reagents and curing them in situ to an elastic sealant. The process is esp. suitable for making air cooled water radiators for automobiles etc. Individual seals are more tolerant of dimensional or alignment variations than prefabricated multi orifice seats or gaskets, and require less sealant material.
