Accumulation, leading to internal temperature is more than the color wheel motor operating temperature upper limit, then can damage color wheel motor, cause under color wheel motor performance
Drop reduces color wheel motor working life.
Currently, ultra short focal projector optical system heat sink conception for the radiating mode at colour wheel position is drawn using fan
Conduction cooling wind flows through colour wheel radome structure surface, is cooled down using cold wind to colour wheel radome structure surface, colour wheel radome structure surface heat
Amount takes away colour wheel radome structure, realizes cold and hot exchange heat dissipation.
By the way of wind-cooling heat dissipating, the superiority and inferiority of heat dissipation effect depends on the flow that cold wind passes through colour wheel radome structure surface,
That is, only keeping relatively high rotation speed of the fan, it can just guarantee enough cold flow and colour wheel radome structure surface
Heat exchange radiate.The drawbacks of this mode is the impossible tick-over of fan, and can be generated when fan high speed operation
Big noise, in addition, radiated using the cold and hot exchange of fan, low efficiency.
