SELF-REGULATED PTC HEATER ARRAY

摘要

The present invention relates to a PTC heater array having a heat dissipation fin (18) and in which an electronic controller (100) is positioned adjacent the heat dissipation fin and the PTC heaters (10). The electronic controller directly controls the heat output of the entire array by delivering a controlled, time-averaged power level to the PTC heaters. The electronic controller is cooled by the heat dissipation fin, and thus contributes to the efficiency of the heater array.
