Construction machine

A construction machine comprising:

• a main body portion that has an engine compartment formed therein;
• an engine that is arranged in the engine compartment;
• a cooling unit that is arranged in the engine compartment and includes a cooling fan configured to blow cooling air whereby cooling the engine, and a cooling core configured to exchange heat with the cooling air;
• an inlet that is formed as opening in a side surface of the main body portion so that the cooling air is drawn into the engine compartment by the cooling fan through the inlet;
• an exhaust gas after-treatment device configured to reduce particulate matter contained in the exhaust gas from the engine, and is arranged on an upper side relative to the engine, the exhaust gas after-treatment device being arranged on the downstream side relative to the cooling fan on a flow path of the cooling air such that the cooling air is blown onto the exhaust gas after-treatment device and guided upward;
• an engine hood that covers the exhaust gas after-treatment device;
• and
• an upper outlet that is arranged immediately above the exhaust gas after-treatment device with the upper outlet partially overlapping the exhaust gas after-treatment device in a top plan view of the construction machine such that the cooling air guided upward by the exhaust gas after-treatment device flows to the upper outlet and is externally discharged through the upper outlet, the upper outlet being formed in at least one of a top surface of the engine hood and a side surface of the engine hood in a front-and-rear direction of the main body, a non-overlapping portion of the upper outlet being disposed on a cooling air upstream side of the exhaust gas after-treatment device in a top plan view.
