Title: PROJECTION DEVICE AND COOLING AND HEAT DISSIPATION SYSTEM THEREOF
Abstract:
A cooling and heat dissipation system of a projection device, and a projection device. The cooling and heat dissipation system of the projection device comprises a light source internal circulation system for dissipating the heat of a solid state light source (1) and a color wheel internal circulation system for dissipating the heat of a color wheel module (2). One of the light source internal circulation system and the color wheel internal circulation system is a water-cooled internal circulation system, and the other is an air-cooled internal circulation system. Moreover, the light source heat exchanger (11) of the light source internal circulation system and the color wheel heat exchanger (13) of the color wheel internal circulation system are both cooled by means of an external air circulation system. The cooling and heat dissipation system of the projection device avoids the adverse effects caused by dust, while effectively reducing the temperature of the solid state light source (1) and the color wheel module (2). The water-cooled heat dissipation and the air-cooled heat dissipation are combined to respectively dissipate the heat of different heat sources of the projection device, taking factors such as heat dissipation efficiency, structural layout and production cost into consideration, having an excellent overall heat dissipation performance.
