Abstract: PURPOSE: A system for controlling oil temperature is provided to prevent a problem about circulation and volume of oil caused by deterioration of oil temperature at a low temperature. CONSTITUTION: A second controller(26) at the end of an oil circuit controls the temperature of oil. Herein, the second controller is interlocked with a temperature controller of a freezing system connected to a three-way valve(24), a first controller(23), and a first heat exchanger(21). In case of heating fluid or oil, a solenoid valve(27) installed at a first oil line is opened while closing a solenoid valve(28) installed at a second oil line(12). In case of controlling temperature, opening degree of the three-way valve, and opening and closing of the solenoid valves are controlled. Therefore, a separate circulating circuit is installed for controlling temperature of engine oil by heat exchange between operating fluid and the engine oil.
