Rack housing for accommodating a plurality of fanless, plug-in components
View Patent ↗A rack housing that accommodates a plurality of fanless, plug-in components includes a plurality of plug-in positions that accommodate the plurality of fanless, plug-in components in a first region of the rack housing bordering a first housing side, at least one installation chamber that accommodates at least one add-on component with at least one fan, and at least one low-pressure chamber in a second region of the rack housing bordering the first region, wherein 1) first openings are provided between the low-pressure chamber and the plug-in positions, which openings allow a discharge of air heated by the plug-in components into the low-pressure chamber, 2) the at least one installation chamber and the at least one low-pressure chamber are essentially decoupled from each other with respect to cooling air, and 3) the installation chamber is connected to the low-pressure chamber via at least one connector for forced ventilation.
1. A rack housing that accommodates a plurality of fanless, plug-in components comprising:
a plurality of plug-in positions that accommodate the plurality of fanless, plug-in components in a first region of the rack housing bordering a first housing side;
at least one installation chamber that accommodates at least one add-on component with at least one fan; and
at least one low-pressure chamber in a second region of the rack housing bordering the first region,
wherein
1) first openings are provided between the low-pressure chamber and the plug-in positions, which openings allow a discharge of air heated by the plug-in components into the low-pressure chamber,
2) the at least one installation chamber and the at least one low-pressure chamber are essentially decoupled from each other with respect to cooling air, and
3) the installation chamber is connected to the low-pressure chamber via at least one connector for forced ventilation.
2. The rack housing according to claim 1 , wherein the installation chamber and the low-pressure chamber are arranged adjacent to one another, and a separating wall between the installation chamber and the low-pressure chamber has at least one second opening as a connector for forced ventilation.
3. The rack housing according to claim 2 , wherein a first ratio between a cross-sectional surface area of a second opening and a surface area of the separating wall is less than 1:10, 1:20, 1:50, 1:100, or 1:500.
4. The rack housing according to claim 1 , further comprising a divider panel arranged between the first and second regions, wherein the first openings are arranged in the divider panel.
5. The rack housing according to claim 4 , wherein a first ratio between a cross-sectional surface area of a second opening and a surface area of a separating wall is less than a ratio between a cross-sectional surface area of the first openings and a surface area of the divider panel.
6. The rack housing according to claim 1 , wherein the installation chamber has at least one third opening for inlet of ambient air from an outer side of the rack housing.
7. The rack housing according to claim 6 , wherein the third opening is arranged underneath the at least one connector such that the third opening is arranged in a lower third of the installation chamber and the connector is arranged in an upper third of the installation chamber.
8. The rack housing according to claim 1 , wherein the installation chamber is shaped and sized for spaced-apart installation of an add-on component so that the at least one add-on component can receive or dissipate air on at least two sides.
9. The rack housing according to claim 1 , having a plurality of installation chambers that accommodate add-on components and/or wherein the at least one installation chamber is sized and shaped to accommodate a plurality of add-on components.
10. The rack housing according to claim 8 , wherein the fanless, plug-in components are data-processing devices, the add-on component is a communications device, and the data-processing devices and the communications device are coupled with each other with respect to data with connector arranged on a first side of the housing.
11. The rack housing according to claim 1 , further comprising an exhaust-air unit with at least one fan unit allocated to at least one fourth opening that draws heated cooling air out from the low-pressure chamber.
12. The rack housing according to claim 2 , further comprising a divider panel arranged between the first and the second regions, wherein the first openings are arranged in the divider panel.
13. The rack housing according to claim 3 , further comprising a divider panel arranged between the first and second regions, wherein the first openings are arranged in the divider panel.
14. The rack housing according to claim 2 , wherein the installation chamber has at least one third opening for inlet of ambient air from an outer side of the rack housing.
15. The rack housing according to claim 3 , wherein the installation chamber has at least one third opening for inlet of ambient air from an outer side of the rack housing.
16. The rack housing according to claim 4 , wherein the installation chamber has at least one third opening for inlet of ambient air from an outer side of the rack housing.
17. The rack housing according to claim 5 , wherein the installation chamber has at least one third opening for inlet of ambient air from an outer side of the rack housing.
