Control System Of Blowing Means For Construction Machines

Abstract

To provide a control system of blowing means for construction machines that enables to prevent the loss of battery charging amount even if an engine rotation speed is low and an alternator generates less electricity. A control system 2 of blowing means for construction machines comprises a heat exchanging means, a blowing means for blowing air to the heat exchanging means, an electric driving means for driving the blowing means, a temperature detecting means for detecting temperature of fluids running through the heat exchanging means, an alternator 4 generating electricity by being driven by an engine 34, and a control means for determining an upper limit rotation speed of the electric driving means based on current generated by the alternator 4 and controlling a rotation speed of the electric driving means based on temperature detected by the temperature detecting means while the rotation speed is below the upper limit rotation speed.
