Abstract
An image projector in a case, having a light engine, a circuit board, a heat sink assembly, and a fan assembly, has one or more heat sinks and heat pipes shaped to gather heat from all heat-generating components within the projector and a single air passage to receive the heated air combined from all components, allowing the employment of a single fan module in sucking cool air from the exterior and exhausting heated air through the single air passage.
