description The invention refers to an electronic control system designed to adjust the optimal rate of the cooling airflow running through the cooling radiator of a thermal engine, through the cooling system of an air cooling engine, through the oil cooling radiator of a hydraulic installation or of the air running through conditioning installations. The system, according to the invention, adjusts the average rate of airflow running through the radiator, according to the temperature of the cooling liquid, the external environment and the oil, using three transducers [1, 2, 3], the information being passed to an evaluation circuit [4] that outputs a quasi-continuous voltage that is compared, using a comparator [5], to a sawtooth-shaped reference signal, from a reference signal generator [6], at the comparator output getting periodical modulated pulses that, applied by a driver stage [7] to an electromagnetic trigger [8] control the "on " and "off" position of the cooling airflow valves, and, using a default setting, the average cooling airflow rate.
