Provided is a projection device including an illumination system, an optical engine module, a projection lens, at least one first case, at least one second case, and at least one optical element. The at least one first case includes a first flow channel to transmit a first fluid therein. The at least one second case is connected to the at least one first case to form an accommodating space. The at least one optical element is disposed in the accommodating space. Heat generated by the at least one optical element is transferred, by the first fluid, to an outside of the at least one first case.

Projection device

A wavelength conversion element and a projector including the wavelength conversion element are provided, which have good heat dissipation performance. The wavelength conversion element includes a turntable, a wavelength conversion layer, and a porous structure. The turntable has a wavelength conversion region and a non-wavelength conversion region, and includes a central axis. The wavelength conversion layer is disposed in the wavelength conversion region of the turntable. The porous structure is disposed in the non-wavelength conversion region of the turntable, and a material of the porous structure includes foamed metal.
