An electronic device has a frame and a back board having plural logical units and power supply units mounted thereon. The logical units and the power supply units are alternately located on both sides of the back board in the center of the frame so that the power supply units mounted on one side of the back board may feed a power to the closest logical units mounted on the other side. Further, the air flow paths to be circulated through the logical units and the power supply units are formed so that each unit may be efficiently cooled by the air fed by an air fan unit. As a result, the feeding voltage becomes uniform and the cooling efficiency is improved.

Mounting structure for electronic device

Computer housing

A forced air cooling apparatus having a blower for blowing air taken in from an intake surface or inlet of the blower to be blown against an electronic device in an installation wherein the blower is mounted for operation on a casing or a rack, and in which the apparatus has a flow regulating plate vertically intersecting the intake surface that is installed immediately before the intake surface. With this construction, eddy air current flow in the vicinity of the intake surface is prevented and the cooling ability obtained from the blower is optimized to thereby attain the effect that the electronic devices can be efficiently cooled without requiring the same separation distance between an intake surface of the blower and a wall surface of the frame or casing in which the blower is installed, as compared with a conventional installation of the same equipment in the same casing without the flow regulating plate.
