OIL COOLER OF VEHICLE TRANSMISSION

摘要

PURPOSE: An oil cooler of a vehicle transmission is provided to improve the quality and performance of an oil cooler by enhancing the cooling efficiency. CONSTITUTION: An oil cooler(15) of a vehicle transmission is received in a fluid space formed by a header and a tank of a radiator. The oil cooler has tubes(21) layered in multiple stages. In a flow space(20) of the tube, an oil center(22) to efficiently cool the oil is embedded. A water center(24) to improve heat exchanger efficiency between the cooling water and the tube is installed in a cooling water space(23). The oil is cooled in the flow space of the tube and discharged. Then, the water center increases the cooling efficiency. The oil is repeatedly cooled by the oil center. The oil center is not interposed in a drain space(26) to keep the smooth flow of oil.
