Device for ventilating cooling air of construction
First Claim
1. A device for ventilating cooling air for cooling a coolant of an engine of a construction vehicle having a water cooled engine within a housing and for reducing the noise of the engine emitted through said device, said device comprising at least one inlet and outlet means mounted on the exterior of said housing for directing cooling air, which dissipates the heat of the coolant, vertically with respect to the body of the vehicle, said inlet and outlet means each comprising a plurality of ducts formed by a plurality of parallel reinforcing ribs and noise-absorbing material which covers the inner surface of said ducts whereby the noise of said engine passing through said inlet and outlet means is substantially reduced.

Abstract
A device for ventilating cooling air for cooling the coolant of a water-cooled engine of a construction machine having inlets and outlets for cooling the air for which dissipates the heat of the coolant of the engine. At least one of said inlets and outlets are directed elevationally upwardly or downwardly with respect to the machinery, and thus the noise generated from the engine is remarkably reduced.
