Abstract

An externally-applied heat exchange pad has three layers laminated together, an inner and outer non-conductive layer and a middle conductive layer. A leak in the inner layer causes coolant to contact the middle layer and change impedance, which can be sensed and used as an indication of an impending total leak of the pad.
