Abstract

An engine room for construction equipment having a noise trap is provided, which can minimize noise, being generated in an engine room due to driving of an engine and a ventilating fan and emitted to an outside of the engine room, through a noise trap, and can prevent a fire caused by high heat of the engine from occurring. The engine room for construction equipment having a noise trap includes an engine, a radiator cooling water for cooling the engine, a shroud fixed to the radiator to form a moving path of external air, a circulating fan making the external air flowing into the engine room through an inlet port pass through the circumference of the engine and discharging the air having passed the engine to an outside of the engine room through an outlet port during rotation of the circulating fan, and a noise trap composed of a frame mounted on one side wall of the engine room and noise attenuation members fixed to the frame in layers so that the noise attenuation members become in contact with the noise emitted from the engine room to the outside of the engine room to shield and attenuate the noise.
