Abstract
The disclosure provides a heat dissipation device including a first fin structure and a heat conduction member. The first fin structure includes a first substrate and a plurality of first fins extending from the first substrate, the first fins include a plurality of first ends and a plurality of second ends. The plurality of first ends and the plurality of second ends are opposite to each other. The first ends are connected to the first substrate. The second ends are away from the first substrate, and the second ends contact the heat conduction member. The disclosure also provides a projector with the heat dissipation device. Through the heat dissipation device, the projector can achieve a good heat dissipation effect.
