    摘要: A projection display apparatus includes an axial fan and a louver. The axial fan includes blades which are rotated to generate an airflow in an axial direction so that air is exhausted from a housing. The louver includes inclined plate portions which are inclined with respect to the axial direction, the inclined plate portions being arranged in a direction perpendicular to the axial direction at an airflow exit side of the axial fan, the louver being divided into a first area and a second area by a straight line which passes through an axial center of the blades, the inclined plate portions being inclined in different directions between the first area and the second area such that the inclined plate portions are inclined along the direction in which the blades are rotated.

    摘要: The invention provides a duct with high sound absorbing effect and sufficient exhausting efficiency, as well as an electronic apparatus having the duct. The duct can include a hollow duct body, an inflated section arranged at an intermediate part of a passage of the duct body, and a sponge bonded on internal surfaces of the duct body and the inflated section. The duct body and the inflated section can have a thickness of 0.25 mm and be formed of a sheet member of paper impregnated with polymethylpentene on the surface thereof. The duct body can also include an intake-port side duct body and an exhaust-port side duct body, which are connected together at an angle of 90° therebetween. Further, a fan can be connected to an intake port of the intake-port side duct body 201. The inflated section can be arranged in the side of the intake port, and the cross-sectional area of the inflated section can be 1.8 times that of the duct body.

    摘要: A light source lamp unit (10) includes a light source lamp (11), an ellipsoidal reflector (12) and a plate body (19). The plate body (19) is provided behind the reflector (12) with a gap kept therebetween, which has a shape corresponding to the profile of a reflecting portion (122) of the reflector (12). A cooling channel for passing a cooling air is formed between the plate body (19) and the reflector (12). The width of the cooling channel in a direction along an optical axis of the light source lamp (11) is minimized at a part near a neck portion (121) of the reflecting portion (122) and enlarged toward the peripheral edge of the reflecting portion (122) of the reflector (12).
