PURPOSE: A cooling system having an independent oil cooler for heavy equipments is provided to use the space efficiently by mounting a charge air cooler in the engine with separating the oil cooler from the engine, to decrease noise by reducing the cooling air amount with distributing cooling air, and to increase thermal efficiency by distributing thermal load. CONSTITUTION: A heavy equipment cooling system comprises a first cooling system(1) having an oil cooler(6) separated from an engine, an oil fan(6a) cooling the oil cooler by blowing, a fan motor(6b) rotating the oil fan and an outer case(8) opening sides to prevent air from the cooling fan from being contacted to blow from the oil fan and discharging hot air, and a second cooling system(2) having a charge air cooler(7) combined with a radiator(5) for supplying cool air to the intake manifold of the engine. The first cooling system cools the oil cooler, and the second cooling system cools the radiator, the charge air cooler and the engine.
