Beschreibung
Zusammenfassung:	[Object] To provide a cooling structure for a construction machine which can efficiently discharge heat generated in batteries and prevent exhaust air of an engine room from being sucked in the batteries. [Solution Means] In a cooling structure for a construction machine, the construction machine including an engine room 5 having an engine 4, a radiator 11 for cooling the engine 4, and a hydraulic pump 7 which are arranged therein, and a counterweight area 6 which is located adjacent to the engine room 5 and in which batteries 27 are installed, a ventilation passage 23 for cooling the engine room 5 and a ventilation passage 34 for cooling the batteries 27 are formed separately and independently in the substantially same direction, and a flowing direction of cooling air flowing in the ventilation passage 23 for cooling the engine room 5 and a flowing direction of cooling air flowing in the ventilation passage 34 for cooling the batteries 27 are substantially parallel to each other.
