PURPOSE: An auxiliary cooling device for a constructing machine is provided to improve the cooling efficiency of a radiator and an oil cooler by mixing outer air generated by the rotation of a cooling fan and moisture generated by a spraying unit. CONSTITUTION: An auxiliary cooling device for a constructing machine comprises a radiator, an oil cooler(3,4), a water tank(6), a spaying unit(8), and an electron controller(10). The radiator and the oil cooler are installed to be adjacent to a cooling fan(2). The radiator and the oil cooler receive outer air(A) according to the rotation of the cooling fan. The spaying unit comprises a blower nozzle. The spaying unit is fixed to the front side of the radiator in order to supply water supplied from the water tank along the outer air. The electron controller is connected to one side of the engine and the spaying unit.
