Abstract: PURPOSE: Structure of a variable multi plate type oil cooler employing a wax body is provided to improve the performance of an engine by varying the heat emission property of an oil cooler via a wax body, to unify the specifications of an oil cooler, and to reduce the production cost by making parts used commonly. CONSTITUTION: An oil cooler(10) includes an ECU(Electronic Control Unit)(20) for variation of the heat emission property depending on the temperature of the oil flowing into the oil cooler, a hot wire(30) for generation of heat, a wax body(40) expanding by the heat of the hot wire, and a plunger(50) for variation of the heat emission property of the oil cooler by controlling the opening and closing of respective inlets of a multi plate(10a). If the temperature of engine oil is low, the hot wire is not heated. The wax is restrained from expanding, and the plunger closes the inlets of the multi plate. Since no voltage is supplied, a bypass path(15) is kept in the open state. The engine oil is bypassed to a main oil gallery. Therefore, the engine oil is preheated at an early state.
