A cooling apparatus of an excavator is composed of a main frame(12) equipped with an engine(10); a cooling fan arranged at the engine to be placed at the right side of the main frame; an arch support(16) having left and right vertical frames(17,18) mounted to the rear of the main frame, and a horizontal frame(19) connecting the upper ends of the left and right vertical frames; a radiator(20) whose lower end is detachably supported at a mounting lever(24) arranged on the main frame and upper end is installed at the right vertical frame; and an oil cooler(30) installed at the right vertical frame to face the radiator. A vortex prevention apparatus(40) is arranged at the upper part of the radiator to preclude the vortex of the air current.
