Definitions

  • the present invention relates in general to a new and improved method and apparatus for mounting computer components. It more particularly relates to such a method and apparatus for rack mounting computer components in a compact configuration.
  • the housing for each computer device must have a certain height dimensions according to the Standard.
  • the height dimension must be a multiple of a standard unit "U”.
  • there can also be standard rack mountable computer components which are 1 U, 2 U, 3 U, 4 U and so on.
  • racks are provided for storage of computer components in tightly spaced, densely packed horizontal dispositions, and each computer component mounted in the rack is suitably dimensioned in multiples of standard unit U.
  • the racks are movably mounted on casters or the like so that they can be readily positioned in, for example, a computer room having a tightly controlled air conditioning system to ensure proper cooling of the computer equipment.
  • each component in order to assemble the rack mounted system for installation at the site, each component must be installed in place within the rack, and then the cabling for each unit is routed within the rack at its back plane space. Such an operation is time consuming, and therefore expensive since highly trained personnel are required to do such an installation. Furthermore, once installed, in order to replace a malfunctioning computer component, the entire system, or at least a substantial portion thereof, must be shut down so that the malfunctioning unit can be disassembled, and a replacement unit installed and reconnected electrically. This, too, is time consuming and expensive.
  • the circuits within the component housing are cooled by providing intake fans to draw air into the housing through the front portion thereof.
  • exhaust fans typically mounted on the side of the housing to exhaust the heated air from within the computer component housing.
  • heat sinks are mounted on circuit components such as microprocessor chips to help dissipate heat build-up therein. The moving air then transfers the heat from the heat sink and is exhausted outside of the component housing.
  • the path of travel of the air is irregular, and thus the placement of the heat sink in the air flow path can be difficult.
  • baffles or the like may be required to direct the air flow through the spaced-apart fins on the heat sink.
  • intake and exhaust fans are employed.
  • the computer component must be taken out of service to either replace the entire computer component or replace or repair the malfunctioning fan or fans. Such a delay in the functioning of the system is highly undesirable for many applications.
