Abstract:
A wavelength conversion device, an illumination device, and a projector that can efficiently cool a phosphor. A wavelength conversion device includes a substrate including a phosphor layer in which a phosphor is included, a rotating device configured to rotate the substrate, a circulating device that circulates a cooling gas to the substrate, and a housing configured to house the substrate and the circulating device. The housing includes a partition wall configured to separate a first space in which the cooling gas is circulated to the substrate by the circulating device and a second space in which the cooling gas radially delivered from the substrate according to the rotation of the substrate circulates.

Claim (Index 7):
A wavelength conversion device comprising:\n a substrate configured to rotate around a rotation axis extending along a first direction; a plurality of fins located on a first surface, which is one surface on the substrate, and extending from a center side toward an outer side of the substrate; a phosphor layer located in either one of the first surface and a second surface on an opposite side of the first surface; a rotating device configured to rotate the substrate; a delivering device configured to deliver the cooling gas to the first surface; and a housing in which the substrate is disposed on an inner side, wherein the housing includes:\n a first side surface section opposed to the second surface; and \n a second side surface section that crosses the first side surface section and includes an arcuate section extending along a circumferential direction during the rotation of the substrate disposed on the inner side when viewed along the first direction, \n a radius of an arc of the arcuate section is set larger than a radius during the rotation of the substrate, when a 12 o'clock direction among radial directions during the rotation of the substrate viewed from the first direction side is set as a second direction and either one of a 3 o'clock direction and a 9 o'clock direction viewed from the first direction side is set as a third direction, a center of the arc of the arcuate section is located on the third direction side with respect to the rotation axis, and the substrate is rotated counterclockwise by the rotating device when viewed from the first direction side.
