METHOD AND DEVICE FOR DETECTING A LEAK IN A HEAT EXCHANGER, ESPECIALLY A PLATE-TYPE HEAT EXCHANGER

摘要

The invention relates to a device for detecting a leak between two circuits of a plate-type heat exchanger (1) provided with means for filling two circuits with fluid at a different pressure, characterized in that said device comprises automatic control means for the convergence of the pressure inside said circuits with respect to a given threshold, and means for signalling a leak when the automatic control means have detected the occurrence of said convergence.
