    摘要： The present invention provides a construction machine having an engine room and capable of efficiently collecting air flowing in the engine room thereby improving exhaust efficiency. The construction machine includes an engine room, an engine, a heat exchanger provided at a first side of the engine, a fan provided at the first side and rotating to generate around the engine a flow of cooling air, and an exhaust duct having an air inlet opening and an air outlet opening and provided in the engine room so as to extend in a fan axial direction parallel with a rotation axis of the fan along the engine. The exhaust duct guides the flow of the air to collect the air flowing downstream of the fan in the fan axial direction, in a region extending in the fan axial direction, and discharge the air to an outside of the engine room.

    摘要： A construction machine includes: a lower propelling body; and an upper slewing body which is slewably mounted on the lower propelling body. The upper slewing body includes: an engine room provided with an intake opening for introducing cooling air from an outside and a discharge opening for discharging cooled air to the outside; a duct provided in the engine room so as to communicate with the discharge opening and adapted to discharge the cooled air to the outside of the engine room from the discharge opening; and an exhaust gas pipe which guides exhaust gas discharged from the engine into the duct. The discharge opening and an outlet of the duct are open downward from the engine room. A portion on a distal end side of the exhaust gas pipe is inserted into the duct. The duct and the exhaust gas pipe are configured to cause the exhaust gas to be mixed with the cooled air in the duct and cause the mixture of the exhaust gas and the cooled air to be discharged downward from the discharge opening.

    摘要： A construction machine includes: an engine room provided with an intake opening and a discharge opening; a fan for sucking cooling air into the engine room through the intake opening; a duct provided in the engine room so as to communicate with the discharge opening and discharging the cooling air sucked into the engine room to an outside of the engine room through the discharge opening; and an exhaust gas pipe guiding exhaust gas discharged from the engine into the duct. A portion on a distal end side of the exhaust gas pipe is inserted into the duct, and the inserted portion of the exhaust gas pipe inserted into the duct is formed with an exhaust hole which causes the exhaust gas to be discharged in a direction different from a flowing direction of discharge wind in the duct through the exhaust hole.
