Control circuit equipped with heating or cooling devices, particularly for direct current fans

摘要

A control circuit (1) is disclosed, particularly for direct current fans (4), comprising a basic circuit (5) equipped with a plurality of external wires (7) and containing at least one microprocessor (9); and a plurality of active components (11), (13) and (15), like driving transistors, diodes and magnetic or optical sensors (for example Hall-effect type or photodiodes). The circuit further comprises at least one heating (16) or cooling element installed in narrow contact with the microprocessor (9) and/or the active components (11, 13, 15).
