Filed: 1986-05-30
Abstract: PURPOSE:To control a DC motor fan at a rotational frequency corresponding to the usage environmental condition of a device and the calorific value of an equipment by detecting temperature rising due to the heating of a part to be cooled, supplying a voltage in accordance with the temperature to a DC motor fan, and controlling the rotation. CONSTITUTION:Since the wind quantity of the DC motor fan 3, namely, its rotational frequency is generally controlled by an input voltage when a wind pressure loss is constant, the DC motor fan 3 is rotated by an output voltage V0. Therefore the wind quantity is controlled by the temperature that a temperature sensor 2 detects. Consequently, the values of resistances 7, 9 and 10 and a variable resistor 8 are suitably selected, whereby the temperature detected by the temperature sensor 2 can be set when the DC motor fan 3 is operated. With the selection of the values of resistors 11 and 16 and a capacitor 17, a potential Vr2 is fully levelled. As a result, the hourly fluctuation of the wind quantity by the DC motor fan 3, which is caused by the delayed response of the temperature sensor 2 can be removed.
