SYSTEM FOR CONTROLLING SPEED OF COOLING FAN FOR AUTOMOBILE RADIATOR

摘要

The present invention relates to a cooling fan speed control device for a radiator of an automobile, and in particular, a low speed, medium speed and high speed gear is installed on a radiator idle shaft connected to an engine, and a solenoid connected to a battery is installed between the respective gears. The solenoid is connected to an electronic control device, and the electronic control device inputs the atmospheric temperature check data, the process coolant temperature data of the transmission, and the engine speed data to the electronic control device. Cooling fan speed control for car radiator to improve fuel efficiency by controlling the rotation speed of cooling fan optimally by selectively controlling the high speed, medium speed, and low speed gears installed on the idle shaft of cooling fan according to temperature change Relates to a device.
