TWO-STAGE COOLING FAN FOR AN ELECTRIC GENERATOR |
摘要 |
<p>An engine driven generator (17) is provided with first and second stage fans (41,42) at one end thereof. The two-stage fan system draws in ambient air and forces it through the generator windings (38) and rotor-stator air gap (37,39) for the purpose of improving generator cooling. Stationary guide vanes (49) are disposed between the two fans (41,42) for the purpose of de-swirling the flow therebetween. The fans are of the centrifugal type and are preferably backward curved.</p> |
