Abstract
The present examples include a rack enclosure with perforations formed within vertical rack columns. Front vertical rack columns may include front perforations formed therein. The front perforations may draw air into the rack enclosure and further into a chassis. Side plenums along the side surface of the chassis may consume less space with the use of the front perforations. The space not consumed by the side plenums may be available to accommodate a chassis of a substantial volume. The chassis may expand a substantial width of the rack enclosure to house an enlarged or a maximum number of computing components within the rack enclosure.
Claims8
A rack enclosure, comprising:
- a rack comprising vertical rack columns, including
- a front vertical rack column, and
- rack panels;
- perforations formed in the front vertical rack column,
- a chassis mounted in the rack, the chassis housing heat-producing components, the chassis having a side surface with openings therein;
- a vertical barrier extending between the side surface of the chassis and one of the rack panels;
- a side plenum bounded by the side surface of the chassis, one of the rack panels, the vertical barrier, and the front vertical rack column such that, when air flows:
- from outside the rack enclosure into the front vertical rack column via the perforations;
- from the front vertical rack column into the side plenum;
- and from the side plenum into the chassis via the openings in the chassis.
A method of cooling heat-producing components, comprising:
- causing air to flow from outside a rack enclosure into a front vertical rack column of a rack of the rack enclosure via perforations formed in the front vertical rack column,
- causing the air to flow from the front vertical rack column into a side plenum of the rack enclosure the side plenum being bounded by a side surface of a chassis mounted in the rack, a side panel of the rack,
- a vertical barrier extending between the side surface of the chassis and the side panel of the rack, and the front vertical rack column:
- causing the air to flow from the side plenum into the chassis via openings in the side surface of the chassis:
- and
- causing the air to be exhausted from a rear of the chassis after being heated in the chassis.
A method comprising:
- providing a rack comprising rack panels including a side rack panel and vertical rack columns including a front vertical rack column comprising perforations;
- mounting a chassis inside the rack such that there is a plenum space between the side rack panel and a side surface of the chassis, wherein the side surface of the chassis comprises openings to allow for air flow into the chassis;
- and
- sealing a vertical barrier between the side rack panel and the side surface of the chassis such that air is directed to flow:
- from outside the rack into the front vertical rack column via the perforations;
- from the front vertical rack column into the plenum space;
- and
- from the plenum space into the chassis via the openings in the side chassis;
- wherein the vertical barrier inhibits communication of air between the plenum space and a rear side of the rack enclosure.
