Abstract
A heat dissipation module and a projection device are provided. The heat dissipation module is used to dissipate heat from an integrating element of the projection device. The integrating element has a light incident surface, a light-emitting surface, and an optical axis. The heat dissipation module includes a rotating member, a first fixing frame, and a second fixing frame. The rotating member is adjacent to the light incident surface and includes a substrate and a driving device. The first fixing frame surrounds the integrating element along a circumferential direction of the integrating element. The first fixing frame has a peripheral surface and fins disposed at intervals. An extending direction of each fin is not parallel to the optical axis. The second fixing frame surrounds along a circumferential direction of the first fixing frame and has a space with the peripheral surface. The fins are disposed in the space.
