ABSTRACT:
An infrared camera is used to detect leakages in a heat exchanger by an imaging process that indicates temperature differences between a heat exchanger and a pressurized gas therein. The temperature differences are created by cooling or heating either the pressurized gas or the heat exchanger, and any leakages are visually observable by the resultant image which is representative of the temperature differences. The process can be accomplished with the use of ambient air rather than the commonly used trace gases which are less desirable because of economical and environmental reasons.
