Abstract
Thermal indictors of this invention are constructed for use with a heat exchanger generally comprising hot and cold side passages for accommodating a desired heat transfer therebetween. The thermal indicator is disposed at least partially within the heat exchanger and is formed from a material designed to undergo a permanent physical change when exposed to a temperature that is above a heat exchanger design operating temperature.
