Ventilation apparatus for an enclosure
First Claim
1. A ventilation apparatus (51) adapted to provide a flow of cooling air to a plurality of components (14) positioned within an enclosure (24) defined by a plurality of sound absorbing panels (36,38,40,104), said ventilation apparatus being characterized by:
- means (52,98) for communicating ambient air from a location outside the enclosure (24) to a location within the enclosure (24), said air communicating means (52,98) forming a circuitous air passageway (54,74,100) that is lined with sound absorptive material and is positioned within at least a first (38) of the plurality of panels (36,38,40,104) defined by the enclosure (24);
a plurality of blowers (78) mounted within the air communicating means (52,98) for drawing ambient air through the air communicating means (52,98) and directing it into the enclosure (24) under a variable flow and pressure; and
means (112,114,116,118) for sensing the temperature within the enclosure (24), said sensing means being operatively associated with the blowers (78) to incrementally adjust the operating speed of all the blowers (78) simultaneously in response to the rise and fall of the temperature within the enclosure (24).

Abstract
The ventilation apparatus (51) of the present invention provides an airflow control system that is designed to minimize noise while providing adequate airflow both during engine operation and after engine shutdown. The enclosure (24) that is divided into first and second compartments (26,28). The first compartment (26) houses the drive train components (14) and the second compartment (28) houses the fluid cooling apparatus (30). The first compartment (26) is provided with at least one air communicating means (52) to transfer ambient air from outside the enclosure through a circuitous air passageway (54) lined with sound absorptive material (60,62). The air passageway (54) is formed in at least one of the walls that forms the first compartment (26) so that it may be critically positioned with respect to the more heat sensitive components (14) housed within the enclosure (24) yet maximizing the efficient use of available space. A plurality of blowers (78) may be included in the air passageway (54) to selectively direct the flow of air toward selected portions of the first compartment (26).
