摘要： A phosphor wheel includes a disc-shaped substrate and a phosphor ring fixedly bonded to the substrate. At least three cut-out sections or openings are formed on a rim of the substrate. The shortest length from the center of the substrate to inner edges of the cut-out sections or inner edges of the openings is generally equal to a radius of an outer circumference of the phosphor ring.

摘要： A cooling device cools down a wheel having a disc shape. The wheel is hermetically enclosed in an enclosure and rotationally driven about a rotation shaft. The cooling device includes blade members that are disposed on one surface of the wheel, a heat dissipater to which a gas heated by the wheel is blown by the blade members due to rotation of the wheel, and a gas flow definer that is located inside the enclosure, and separates a flow path along which the gas that has been cooled by the heat dissipater flows before being blown to the one surface and a flow path along which the gas that has been blown to the one surface and heated flows.

摘要： A disk-shaped substrate made of a heat conductive material is provided with, along an outer periphery of one surface of the substrate, a ring-shaped phosphor that emits light by irradiation with blue laser light that is excitation light. The substrate is provided with, on another surface of the substrate, a plurality of convex portions dotting a region corresponding to a region provided with the phosphor. In a phosphor wheel, the substrate is driven by a motor to rotate about an axis of rotation.

摘要： A cooling device of a projection display apparatus includes a first heat receiving unit including an opening that is rectangular. The first heat receiving unit includes a flow path part that forms the opening. An image display element of the projection display apparatus includes a first front face located in front of a reflective image display, a second front face parallel to the first front face and located behind and outside the first front face, and a first side face located between the first front face and the second front face. The first front face is inserted into the opening, and the flow path part is in contact with the first side face and the second front face via a heat conductive member. The flow path part includes a front face that is flush with or in front of the first front face of the image display element.

摘要： A heat exchanger includes a plurality of heat exchange tubes stacked with a gap through which a first fluid can pass. The heat exchange tube includes: an internal flow path through which a second fluid for exchanging heat with the first fluid and which includes a folded portion; a plurality of slits provided between two flow path portions in the internal flow paths, the two flow path portions each extending from the folded portion and facing each other at an interval; and a plurality of protruding support portions in contact with another adjacent heat exchange tube to form the gap. As viewed in a stacking direction of the plurality of heat exchange tubes, at least one of the plurality of slits extends in a state where a center in an extending direction thereof deviates from a straight line connecting the two adjacent protruding support portions.
