Abstract
In a cooling structure for a construction machine, to appropriately install a condenser of an air conditioning system in a machine room to thereby ensure a superior cooling ability for a radiator and a oil cooler, while cooling the condenser, open air sucked by a fan through the intake ports cools a condenser, an oil cooler and a radiator successively, following which it is discharged to the outside through exhaust ports. The oil cooler is erected parallel to the radiator, while the condenser is inclined so as to extend from a portion near a lower end of the uppermost intake port formed in a side wall of an engine cover to a position near a lower end of the side-facing surface of the oil cooler.
Claims2
In a construction machine having a frame;
- an engine mounted on said frame within an engine compartment and including a rotatable fan;
- an oil cooler supported on said frame within said engine compartment;
- a radiator supported on said frame within said engine compartment;
- and an air conditioning condenser supported on said frame within said engine compartment, said engine compartment including a first intake port formed in an upper side part of said engine compartment, a second intake port formed in a side part of said engine compartment at a position lower than said first intake port, ambient air being sucked by said fan when rotated by said engine through said first and second intake ports to flow through and cool said condenser, said oil cooler and said radiator, said ambient air after being used for the cooling being discharged through an engine cover at the top of said engine compartment, the improvement comprising:
- said condenser is inclined so as to extend from a portion near a lower end of said first intake port formed in the side part of the engine compartment to a position near a lower end of said oil cooler whereby the condenser serves as a guide plate for the ambient air sucked though the first inlet port.
