Title:
ENGINE COOLER AND CONSTRUCTION MACHINES
Document Type and Number:
WIPO Patent Application WO/1997/014874
Kind Code:
A1
Abstract:
First cooling air (50) enters an engine room (1) from outside through a cooling air inlet (7a), passes through a heat exchanger such as an inter-cooler (6a)/oil cooler (6b)/radiator (6c), is throttled by a suction pipe (8a) and enters a centrifugal fan (4). It is then discharged in an outer peripheral direction of the centrifugal fan (4). Second cooling air enters the engine room (1) from outside the engine room (1) through cooling air inlets (7b, 7b), and cools the engine (5), various electrical components such as an alternator (10) and an oil pan (14) while flowing around them. It is then throttled by a suction pipe (8b), enters the centrifugal fan (4) and is discharged in the outer peripheral direction of the centrifugal fan (4). These two kinds of cooling air (50, 51) are discharged to the outside from an exhaust port (9). Therefore, the degree of sealing of the engine (5) can be improved, the noise can be reduced and reliability of the electrical components (10) can be improved by improving the cooling effect for them.
