CONSTRUCTION MACHINE

摘要

A construction machine which has an air-cooled EGR cooler placed near a cooling fan and achieving high cooling efficiency without a reduction in cooling effect of a heat exchanger. The construction machine has an EGR pipe path (20) for extracting a part of exhaust gas from the exhaust side of an engine (9) and recirculating the extracted exhaust gas to the air intake side, and also has the air-cooled EGR cooler (21) for cooling the recirculating gas flowing in the EGR pipe path (20). The air-cooled EGR cooler (21) is placed at a position between the engine (9) and the cooling fan (11), that is, a position which is downstream of the cooling fan (11) and on the outer peripheral side of the cooling fan (11), and the air-cooled EGR cooler (21) is cooled by cooling air flowing on the outer peripheral side of the cooling fan (11).
