The present invention forms an inlet grill in all four directions so that the same air inflow is made in all directions, and uniform air flow is introduced between all the fans so that a large amount of air is concentrated at a certain part of the fan to suppress the loud noise generated by colliding with the fan. The inlet grill is provided with air in one direction to improve cooling performance as well as to improve cooling performance. The upper and lower left and right sides of the outer casing are broken, and the inlet grill consisting of upper, lower, left and right plates is installed and fixed to the broken section. It is characterized in that the uniformly distributed air is supplied to all the sections of the fan, by which the present invention is a uniform air flow flows into the entire area of the fan through the inlet grille up, down, left and right, so that the air flow is concentrated in a certain portion of the fan Not only can it suppress the generation of loud noises, but also the amount of air in the radiator Since it supplies uniformly, it also has the advantage of improving cooling performance at the same time. As a result, not only can the noise emitted to the outside reduce noise pollution, but also the cooling performance is improved, thereby protecting the engine and extending the life.
