<p>[Problem] To provide a construction machine wherein it is possible to prevent the temperature of a battery and aqueous urea within an aqueous urea tank from rising and to ensure high vehicle stability. [Solution] A small revolving hydraulic shovel (1) provided with: a counter weight (6) disposed on the rear end of a revolving body (3) of which the front is disposed with a front work machine (4); an engine (5a) disposed within an engine room (5) that is in front of the counter weight (6); a heat exchanger (15) for exchanging heat with the engine (5a); a fan (16) for bringing in outside air from an intake port (5b) formed on the exterior of the engine room (5) into the engine room (5) and for cooling the heat exchanger (15); a tail pipe (20) disposed on the exterior of the engine room (5); an aqueous urea tank (12) for storing aqueous urea which purifies the exhaust gas discharged from the engine (5a); and batteries (13a, 13b) for supplying power to the engine (5a). The aqueous urea tank (12) and the batteries (13a, 13b) are disposed further upstream of the outside air flow than the heat exchanger (15).</p> |
