Abstract
The invention provides a projection device. The projection device includes a housing, an optical engine, a projection lens, a plurality of first fans and a heat dissipating module. The housing has an air inlet and an air outlet. The optical engine is configured in the housing, and includes a plurality of heating elements. The projection lens is connected to the optical engine. The heat dissipating module is configured in the housing, and the heat dissipating module includes a first heat dissipating fin. One of the plurality of first fans is adjacent to the first heat dissipating fin, and another of the plurality of first fans is away from the first heat dissipating fin. There is no the first heat dissipating fin between the air inlet and the another, away from the first heat dissipating fin, of the plurality of first fans.
