Typically, multiple racks, frames, cabinets, and the like (sometimes collectively referred to hereinafter as “enclosures”) are housed together in a data center. Because of the overheating problem, and particularly with multiple enclosures being placed in a single room or other enclosed space, thermal management of the data center is very important. A goal of data center thermal management is to maximize the performance, uptime and life expectancy of the active components being housed in the data center. This goal is generally accomplished by managing the cold air delivered to each component such that the internal temperature of the component does not exceed the manufacturer's maximum allowable operating temperature.
Preferably, the cold air delivered to the component is at or below the manufacturer's recommended temperature and in sufficient volume to meet the airflow requirements of the component, which are typically measured in cubic feet per minute (CFM).
1. A method of venting heated air from an electronic equipment enclosure, comprising:
(a) installing a frame structure formed from a plurality of support posts and cross members, wherein the frame structure defines a front, a back, a left side, a right side, a top, and a bottom;
(b) mounting a top panel on the top of the frame structure such that a large rectangular opening is formed at the top of the frame structure, the large rectangular opening including a rear edge adjacent the back of the frame structure, a left edge adjacent the left side of the frame structure, and a right edge adjacent the right side of the frame structure, and a front edge;
(c) mounting a left side panel on the left side of the frame structure, a right side panel on the right side of the frame structure, and an air-impervious rear panel on the back of the frame structure, wherein the panels define a single compartment, and wherein the panels and the frame structure define an electronic equipment enclosure;
(d) installing a plurality of electronic components within the compartment, wherein the plurality of electronic components are arranged in a column that is nearer the front of the frame structure than the back of the frame structure such that a columnar space exists between a rear of the column of electronic components and the air-impervious rear panel, and wherein the large rectangular opening at the top of the frame structure substantially overlaps the columnar space between the rear of the column of electronic components and the air-impervious rear panel;
(e) installing a vertical exhaust duct at the top of the frame structure, wherein the vertical exhaust duct has a rectangular cross-section that is congruent with, and aligned with, the large rectangular opening at the top of the frame structure, wherein the vertical exhaust duct includes a first exhaust duct section and a second exhaust duct section, wherein the second exhaust duct section is vertically translatable relative to the first exhaust duct section, and wherein installing the vertical exhaust duct includes:
(i) attaching the vertical exhaust duct to a top of the electronic equipment enclosure such that an interior of the vertical exhaust duct is in direct fluid communication with the columnar space via the large rectangular opening and substantially overlaps the columnar space between the rear of the column of electronic components and the air-impervious rear panel, and
(ii) translating the second exhaust duct section relative to the first exhaust duct section to achieve a desired overall height of a top of the vertical exhaust duct;
(f) operating the installed electronic components within the compartment such that heated air is produced as a byproduct and exhausted therefrom into the columnar space; and
(g) via air currents, passively routing the heated air directly upward, via the columnar space, from the rear of the column of electronic components to the large rectangular opening and through the large rectangular opening into the vertical exhaust duct.
7. A method of venting heated air from an electronic equipment enclosure, comprising:
(d) installing an electronic component within the compartment and nearer the front of the frame structure than the back of the frame structure such that a gap exists between a rear of the electronic component and the air-impervious rear panel, and wherein the large rectangular opening at the top of the frame structure substantially overlaps the gap between the rear of the electronic component and the air-impervious rear panel;
(i) attaching the vertical exhaust duct to a top of the electronic equipment enclosure such that an interior of the vertical exhaust duct is in direct fluid communication with an interior of the compartment via the large rectangular opening and substantially overlaps the gap between the rear of the electronic component and the air-impervious rear panel, and
(f) operating the installed electronic component within the compartment such that heated air is produced as a byproduct and exhausted therefrom; and
(g) routing the heated air directly upward through the gap to the large rectangular opening and through the large rectangular opening into the vertical exhaust duct.
14. A method of venting heated air from an electronic equipment enclosure, comprising:
(a) installing a frame structure formed from a plurality of support posts and cross members, the frame structure defining a front, a back, a left side, a right side, a top, and a bottom;
(b) enclosing the frame structure with a plurality of panels, the plurality of panels including at least a left side panel arranged at the left side of the frame structure, a right side panel arranged at the right side of the frame structure, an air-impervious rear panel arranged at the back of the frame structure, and a top panel arranged at the top of the frame structure, wherein the top panel defines a large pass-through opening that is disposed closer to a back edge of the top panel than a front edge of the top panel and that is sized to extend generally from a left side edge of the top panel to a right side edge of the panel, and wherein the panels and the frame structure define an electronic equipment enclosure;
(c) installing an electronic component within the enclosure and nearer the front of the frame structure than the back of the frame structure such that a gap exists between a rear of the electronic component and the air-impervious rear panel, and wherein the large opening defined by the top panel at least substantially overlaps the gap between the rear of the electronic component and the air-impervious rear panel;
(d) installing a low-friction, self-supporting exhaust duct at the top of the frame structure and against the top panel, the exhaust duct having a cross-section that is congruent with, and aligned with, the large opening defined by the top panel such that an interior of the exhaust duct is in direct fluid communication with an interior of the enclosure via the large opening defined by the top panel and substantially overlaps the gap between the rear of the electronic component and the air-impervious rear panel, wherein the exhaust duct includes a first exhaust duct section and a second exhaust duct section, the second exhaust duct section being translatable relative to the first exhaust duct section;
(e) translating the second exhaust duct section relative to the first exhaust duct section to facilitate adjustment of a desired overall length of the exhaust duct;
(f) operating the installed electronic component within the enclosure such that heated air is produced as a byproduct and exhausted therefrom; and
(g) routing the heated air directly upward through the gap to the large opening and through the large opening into the exhaust duct.
