A small network computer has a chassis which is mounted within a housing. A variety of electronic components are mounted to the chassis and a pair of feature card slots are located in a tailstock portion of the chassis. A full-sized 3.5 inch hard disk drive is mounted to a flat bracket in one of the feature card slots. The bracket inserts into the tailstock on one end and is fastened to the chassis on an opposite end.

Mechanical architecture of supporting a hard disk drive into a feature card slot in a network computer

A network computer has a chassis with four wall-like frame members located at its rectangular perimeter. A motherboard having a variety of electronic components is mounted to the chassis within the rectangular perimeter. The chassis is mounted within a metallic enclosure with very small clearances between the components on the motherboard and the enclosure. The enclosure closely receives the chassis to eliminate excessive movement therebetween and to minimize the size of the computer. A strut extends between the frame members for enhancing the strength of the chassis and protecting the components. The strut has insulated stand-offs which are rigidly secured to and extend through the motherboard. The ends of the stand-offs are also very close to or in contact with sidewalls of the enclosure. The strut protects the components from being short circuited to the sidewalls by transmitting force on one of the sidewalls through the stand-offs to the other sidewall.

Packaging apparatus and method for networks computer chassis

A computer has an internal chassis with four wall-like frame members located at its rectangular perimeter. A variety of electronic components are mounted to the chassis within the rectangular perimeter. A bezel is mounted to an outer portion of one of the frame members and forms an exterior rear panel of the computer. The chassis is sidably mounted within an integral, five-sided enclosure having a rectangular opening at its rearward end. The enclosure closely receives the chassis to eliminate relative movement therebetween. The bezel has an integral handle with a pair of tabs which engage recesses in the enclosure when the chassis is in the enclosure. The chassis is removed from the enclosure by lifting the handle on the bezel such that the tabs disengage the recesses in the enclosure to allow the chassis to slide out of the enclosure.

Quick-release computer chassis

A computer has a chassis with a variety of electronic components mounted to it. The chassis is generally rectangular and slidably mounted within a sheet metal enclosure. The enclosure closely receives the chassis to eliminate excessive movement therebetween. The enclosure is essentially a four-sided box with an opening at either end. A front panel is attached to one of the openings. The front panel and the enclosure each contain half of a labyrinth seal which seals one end of the enclosure when the front panel is assembled to the enclosure. A similar seal is formed at the other end of the enclosure when the chassis is mounted in the enclosure. The labyrinth seals have a folded configuration which forms an interleaving arrangement.

Integral EMI shielding for computer enclosures

A computer has an internal chassis with a variety of electronic components including a power supply and a ventilation fan. The chassis is mounted within an enclosure which has having a ventilation port for exhaust air near a lower end. The power supply and ventilation fan are located at the bottom of the enclosure to lower the center of gravity of the computer and increase its overall stability while maintaining proper cooling efficiencies.

Reverse convective airflow cooling of computer enclosure

A computer has an internal chassis which is mounted within an enclosure. A variety of electronic components including a motherboard, a power supply and a ventilation fan are mounted to the chassis. The power supply has a small housing located within the enclosure. The housing is shaped to span the motherboard and requires no ducting. The ventilation fan is mounted to an inlet opening of the housing so that air is forced through the power supply before exiting the enclosure. The ventilation fan also pressurizes the housing such that a small, strategically located vent may be used to allow impingement cooling of other motherboard components.

Use of pressurized enclosure for impingement cooling of electronic

A computer has an internal chassis with a variety of electronic components. The chassis is mounted within an enclosure having a ventilation port for exhaust air on a lower surface. A diffuser is mounted to the lower end of the enclosure. The diffuser has a series of openings and baffles which align with the ventilation port for directing the flow of exhaust air away from either side of the computer. The diffuser also allows for full containment of hot or flaming parts to satisfy safety codes. In addition, a pedestal is detachably coupled to the diffuser and is configured to enhance the air flow performance of the diffuser.
