<p>A display component-used channel-type heat radiator in a projecting system, includes a display component, an adjacent component which is adjacent to the display component, a fan and two covering plates provided on a upper side and a lower side of the display component and the adjacent component. A heat-dissipation channel is formed by a gap formed among the display component, the adjacent component, the fan and two covering plates, and the fan is provided at a inlet port of the heat dissipation channel in such manner that the exhaust port of the fan towards the display component. It has a simple and reasonable structure, establishes a channel to make the air blow through the display component along a specified path, and makes the fan have directionality, and thus it has a good heat-dissipation performance, largely increases the utilization ratio of wind from the fan, reduces the cost and power consumption of fan and simultaneously retains smaller bulk of fan.</p> |
