Cooling structure for construction machine
First Claim
1. 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, andwherein;
a ventilation duct that connects the air intake port and an air exhaust port for cooling air for cooling the batteries to form the ventilation passage for cooling the batteries is provided in the counterweight area; and
the batteries are installed in the ventilation duct.
