    摘要: An exhaust cooling apparatus for construction equipment, having a cooling fan taking external air into an engine room for heat exchange with a oil cooler and a radiator, and a blower flowing air out of the engine room to the atmosphere. In the apparatus, an outlet of an exhaust pipe for emitting exhaust gas from an engine is fixedly disposed toward a discharge direction of the blower. The discharge direction of the blower is upwardly vertical to the ground. The exhaust cooling apparatus is effective in preventing combustible matters from burning, or preventing plant lives from withering, due to hot exhaust gas around construction equipment such as excavator, by discharging the hot exhaust gas to the atmosphere after cooling it down through air flowing out of the engine room.
