摘要

Process and device for the detection of leakage in a heat exchanger, especially with plates ".This device for detecting a leakage between the two circuits of a heat exchanger plates (1), of the type which includes means for filling with fluid under a pressure different.Each of the two circuits is characterized by the fact of understanding means for automatic control of the approximation of the pressures in the two circuits in relation to a specified limit and means of markThen an exhaust function, when the means of automatic control have found this approximation.
