Cooling structure for construction machine

A cooling structure for a construction machine, the construction machine comprising:

• an engine room including an engine, a radiator for cooling the engine, and a hydraulic pump;
• and
• a counterweight area including batteries,
• wherein:
• a ventilation passage for cooling the engine room and a ventilation passage for cooling the batteries are formed separately and independently;
• and
• an air exhaust port of the ventilation passage for cooling the engine room and an air intake port of the ventilation passage for cooling the batteries are formed in different surfaces to each other, and
• wherein a guide part that guides a flow of cooling air is installed in the ventilation passage for cooling the batteries.
