Abstract
A circuit for monitoring the heat dissipation capacity of a cooling medium by defining the initial heat dissipation capacity of the medium at a predetermined temperature of a temperature-sensitive element immersed in the medium. The circuit senses a change in temperature of the element and restores the temperature of the element to the predetermined temperature. Based on the level of power required to restore the temperature of the element to the predetermined temperature, the circuit defines the adjustment in heat dissipation capacity of the medium required to return the medium to the initial capacity. Also disclosed is a system including such a circuit which modifies the heat dissipation capacity of the medium by the required adjustment to return the medium to the initial heat dissipation capacity.
