The present invention relates to an oil cooler apparatus comprising an oil cooler (100) having one end connected with a hydraulic pressure unit (101) for receiving operation oil, and the other end connected with an oil tank (102) for delivering operation oil while allowing the operation oil to maintain an optimum temperature; an opening and closing unit for flow path (110) formed in the upper part inside the oil cooler (100) for connecting the pipe (101P) connected to the hydraulic pressure unit (101) and the pipe (102P) connected to the oil tank (102); a core (120) positioned in the lower part of the opening and closing unit for flow path (110) for delivering the operation oil to the oil tank (102) after cooling upon inflow while being provided inside the oil cooler (100); and a control unit connected with the oil cooler (100) for measuring temperatures of the operation oil and for operating the opening and closing unit for flow path (110). The invention can improve marketability through improvement of efficiency and durability of the oil cooler (100) by minimizing oil cooling at low temperatures and by delivering the operation oil at an optimum temperature. |
