Abstract
A detection mechanism for monitoring airflow in an electronics enclosure includes a first thermal sensor positioned proximate the enclosure for measuring an ambient air temperature and a second thermal sensor positioned proximate an exit air stream for measuring the temperature of air that is heated by the electronics in the enclosure. A control circuit is coupled with the first and second thermal sensors and is configured for determining a temperature differential between the measured temperatures of the thermal sensors. The control circuit may initiate an alarm when the temperature differential exceeds a setpoint thereby indicating restricted airflow in the enclosure. The control circuit might also take other remedial steps prior to initiating the alarm.
