<p>A method and apparatus of providing temperature controlled fluid flow through the use of a plurality of positive temperature coefficient thermistors (26) disposed in physical series in heat exchange relation with the fluid. The method and apparatus can be used to maintain output air temperature substantially constant over a range of airflow rates, or alternatively can be used to vary output temperature while the airflow rate is held constant. The thermistors (26) are preferably disposed within a conduit structure (10), with fluid flowing longitudinally through the conduit structure (10). In the illustrated embodiment, the method and apparatus are employed for acceleration of setting and drying of liquid media on stock in a printing operation.</p> |
