Abstract

Provided in the invention is a projection device comprising a housing, an optical machine assembly, a fan, and a lamp holder. The housing has a first air port and a second air port, wherein the two ports are opposite to each other. The optical machine assembly is arranged in the housing. The fan arranged in the housing is used for generating an air flow and has an axis. The lamp holder facing the axis directly is connected with an external power supply and has a first cross section; and the area of the first cross section matches the area of the cross section of the axis. The air flow can flow along a linear air flue between the first air port and the second air port to cool the optical machine assembly. Therefore, the air flue structure can be optimized and thus the maximum air flow can be obtained.
