ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to new and improved ventilation of a desktop workstation. More particularly the invention relates to ventilation of the workstation by curving the bezel on the front of the casing on the work station so that there is a gap between the bezel and the front edges of the sides of the casing.
2. Related Art
Workstations are frequently provided with bezels on the front thereof formed with apertures for ventilation purposes. A conventional fan within the workstation casing draws air through openings in the front face of the bezel so that there is an appreciable amount of noise caused by the airflow. The present invention is distinguishable from such prior constructions in that the bezel is bowed outward so there is a gap on the sides of the casing through which ventilation air enters the casing. This achieves considerable acoustic benefit.
SUMMARY OF THE INVENTION
A generally rectangular “desktop” type casing for a workstation or other electronic device contains heat-emitting components. A fan located within the casing draws air through the front and out through the back or the rear portions of the sides of the casing. An ornamental bezel closes off the front of the casing. At least portions of the bezel are curved outwardly so that there are gaps between the front edges of the sides of the casing and the bezel through which ventilation air may be drawn. The absence of airflow through the front is of acoustic benefit and the area of the opening into the interior of the casing is not reduced, as is the case in conventional bezels.
Acoustic absorbing foam may be applied to the back of the bezel so that if there is any tendency for air to reverse flow out through the bezel it is absorbed by the foam. The acoustic padding also absorbs some of the noise of the fan located inside the casing.
One of the features of the invention is the fact that the bezel is readily installed and removed. Only two screws are required and the screws themselves are concealed by a media bezel which is installed in the main bezel.
Openings are formed in the front face of workstations for insertion of disk drives, floppy disks and the like. Customarily there are openings in the front for what may be termed “media” accessories. The present main bezel is formed with an opening at the top to receive a media bezel. The ease of attachment of the media bezel is one of the features of the invention. As has also been mentioned, the placement of the media bezel conceals the screws which attach the main bezel to the casing.
