Patent ID: 8657863

Claim:
A system adapted to thermally affect a gaseous medium for dermatological applications, the system comprising: a plurality of thermally controlled flow tunnels having inlets and outlets; an air mover that facilitates creation of a pressure differential to impart airflow to a gaseous medium through the plurality of thermally controlled flow tunnels; a plurality of thermoelectric coolers thermally coupled to the plurality of thermally controlled flow tunnels and that actively remove heat therefrom to cool the gaseous medium flowing therethrough; a sensor exposed to the gaseous medium and that monitors at least one indicator relative to the flow of the gaseous medium through the plurality of thermally controlled flow tunnels and send a signal if a hydraulic diameter of at least one of the plurality of thermally controlled flow tunnels decreases; and wherein the amount of heat being actively removed by at least one of the plurality of thermoelectric coolers from at least one of the plurality of thermally controlled flow tunnels is reduced in response to the signal, while maintaining flow of the gaseous medium through the plurality of thermally controlled flow tunnels.
