Title: COOLING DEVICE, ELECTRONIC APPARATUS AND PROJECTION-TYPE DISPLAY DEVICE
Abstract:
This cooling device (11) air-cools a heat-generating portion within an electronic apparatus, the cooling device comprising a fan (3) generating a cooling airflow (12), and vibration-generating means (19a) causing fluid-induced vibrations to be generated by the cooling airflow being blown toward the heat-generating portion. This electronic apparatus comprises the cooling device, and the heat-generating portion which is the object to be cooled by the cooling device. This projection-type display device displays an image by projection, the projection-type display device comprising the cooling device, and a liquid crystal unit (2) serving as the heat-generating portion that is the object to be cooled by the cooling device, the liquid crystal unit (2) being where an image to be projected is formed.
