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 fan structure including a center portion, multiple fan blades, and a fixing ring is provided. The center portion includes a bottom surface and a center shaft. The center shaft is perpendicular to the bottom surface, and the direction in which the center shaft extends is an axial direction. The fan blades are mutually separated and connected to the bottom surface of the center portion and are disposed around the axial direction. Each of the fan blades has a height which is parallel to the axial direction. The fixing ring simultaneously contacts the side of the fan blades which is away from the center shaft. Along the axial direction, with the bottom surface of the center portion as a reference surface, the fixing ring is disposed at a range of 40% to 80% of the height of each of the fan blades.

Abstract: A wavelength conversion element, including a turntable, is provided. The turntable is configured to rotate along a central axis. The turntable has a first surface and a plurality of first turbulence portions and a plurality of second turbulence portions located on the first surface, wherein the first turbulence portions and the second turbulence portions are arranged by surrounding the central axis, a shape of each of the first turbulence portions is different from a shape of each of the second turbulence portions, and at least one of the second turbulence portions is arranged between two adjacent first turbulence portions of the first turbulence portions. A projector, including the wavelength conversion element, is further provided. The wavelength conversion element and the projector effectively improve the heat dissipation effect.

Abstract: The disclosure provides a fan module and an electronic device. The fan module includes a hub and a plurality of blades. The blades are mounted around the hub, and each of the blades has a first end is connected to a periphery of the hub and a second end that is relatively away from the hub. A first axial direction distance in the axial direction is provided between a first point of the first end that is relative away from the top surface and the top surface. A second axial direction distance in the axial direction is provided between a second point of the first end that is near the top surface and the top surface. A ratio of the second axial direction distance to the first axial direction distance is 0.4 to 0.5.
