HIGH-PERFORMANCE OIL COOLER APPARATUS FOR SPECIAL VEHICLE HAVING AUTOMATIC FAN MOTOR CONTROL LOGIC

摘要

The present invention relates to a high-performance oil cooler apparatus for a special vehicle having an automatic fan motor control logic, which is able to develop a component-customized oil cooler optimized for a special feature vehicle, and to provide a control logic with a variable RPM count of a fan in accordance with a change in the temperature of oil. According to the present invention, the high-performance oil cooler apparatus for the special vehicle having the automatic fan motor control logic comprises a controller which, when a power is applied from a power supply unit, receives an input signal of a fan motor operation switch and an oil temperature sensor, and determines whether to operate the fan motor or not. The fan motor operation switch has an off mode, a manual mode, and an auto mode. When the fan motor operation switch is in the off mode, the controller stops the operation of the fan motor. When the fan motor operation switch is in the manual mode, the controller controls the fan motor to operate all the time. When the fan motor operation switch is in the auto mode, the controller allows the speed of the fan motor to be automatically controlled in accordance with the temperature entered from the oil temperature sensor. When the fan motor is automatically controlled, an oil temperature value read from the oil temperature sensor, is entered into the Micom through an A/D conversion on the controller. The Micom controls the amount of current flowing in the field effect transistor (FET) in accordance with the entered value, and controls the speed of the fan motor automatically.;COPYRIGHT KIPO 2019
