Abstract: A wavelength conversion module includes a driving element, a wavelength conversion wheel, and at least one flow guide. The wavelength conversion wheel includes a rotary disc and at least one wavelength conversion layer. The driving element is connected to the rotary disc to drive the wavelength conversion wheel to rotate along an axis of the driving element as a central axis. The flow guide is disposed beside the wavelength conversion wheel at intervals along the axis, and at least one airflow channel is formed between the flow guide and the wavelength conversion wheel. The flow guide and the driving element are disposed at intervals, and the flow guide does not contact the rotary disc and the driving element. An orthographic projection of the flow guide on the rotary disc overlaps the wavelength conversion layer. When the wavelength conversion wheel rotates, the wavelength conversion wheel and the flow guide move relatively.

Abstract: A heat dissipation module, configured for heat dissipation of at least one first heat source and at least one second heat source, and including a first heat sink, a second heat sink, a first pipe, and a second pipe, is provided. The first heat sink and the first heat source are connected to each other through the first pipe to form a first loop, so that a liquid medium flows through the first heat sink for heat exchange and then flows to the first heat source for circulating heat dissipation. The second heat sink and the second heat source are connected to each other through the second pipe to form a second loop, so that the liquid medium flows through the second heat sink for heat exchange and then flows to the second heat source for circulating heat dissipation. A projection device, including the heat dissipation module, is also provided.
