  • Jet cooling apparatus for cooling electronic equipment and computer having the same mounted thereon
    Patent number: 5428503
    Abstract: A cooling apparatus for electronic equipment for improving the reliability of the equipment by making uniform the temperature distribution of heat generating devices mounted on the electronic equipment, more particularly on a computer and for reducing the working process required at the time of performing a maintenance of a printed circuit board in the electronic equipment by stacking, in a frame, the electronic printed circuit boards on which the heat generating devices, such as a CPU and memories, are mounted at predetermined intervals. The cooling apparatus has a fan fastened to one wall surface of a chamber and a plurality of jet cooling devices formed on the surface opposing the wall surface. The jet cooling devices are formed in parallel to the printed circuit boards. The jet cooling devices are slits, or nozzles or jet stream ducts extending among the printed circuit boards and are so formed as to supply cooling air in a jet stream state to each heat generating device.
