  • Patent number: 5721670
    Abstract: Electronic equipment having a fan cooling arrangement with a fan structure mounted at the rear of the housing. The fan structure is mounted vertically in operational position. An access opening at the front of the housing is of lesser height than the fan structure. It is desired to withdraw the fan structure from the housing through the restricted access opening. For this purpose, the fan structure is pivotally mounted to a mounting. The fan structure is sprung into its vertical position and is withdrawn upon the mounting through the access opening. During withdrawal, the fan structure is pivoted downwards automatically against its spring to allow for its withdrawal in a horizontal as distinct from a vertical position.
