A noise reduction duct for an engine room of heavy construction equipment is provided to reduce noise transferred to the outside of the engine room by mounting a plurality of wave blades having first and second wave bodies on the air path. An air path is communicated with a radiator(1), a cooling fan(9), an engine room(2), and a grille of an upper cover to restrict the noise caused from the inside of the engine room. A body is installed to one side of the front side of the radiator. The body is formed with a plurality of wave blades(21) with a predetermined gap. A plurality of noise interference paths are placed between the wave blades to be communicated with the air paths. The wave blades connect the first and second wave bodies integrally. |
