In the fault area of the outdoor cabinet, the cabinet is usually made of cold rolled steel or alloy, which is used to store computer and related control equipment. It can provide protection for storage equipment, shield electromagnetic interference, arrange equipment in an orderly and orderly manner, and facilitate the maintenance of equipment in the future. Cabinet is generally divided into server cabinet, network cabinet, console cabinet and so on. As the user of cabinet, you must know the fault area of cabinet.
Fault area 1: below the cabinet (outside the cabinet)
The area below the rack and above the floor is difficult to manage because leveling bolts or casters vary in size and manufacturer and height. There will be a lot of uncontrolled air in this area. If the area can be properly sealed, it can produce very high benefits. Usually, there is no solid baffle under the cabinet due to the need to connect wires or nets. This will also lead to air leakage in the area, because the heat under the cabinet cannot be released, and the cold air from the perforated floor will also bypass the area.
Fault area 2 and the left and right sides of 3:19 inch cabinet front vertical rail (cabinet interior)
Because customers require that the front-end guide rail can be adjusted and they want to be able to pass through cabinet wiring, most 19-inch cabinet front-end guide rail has leakage points on both sides. The area between the vertical guide rail and the rack or side panel is usually open, allowing hot air to penetrate or cold air to pass through. This will seriously damage the stability of blind strategy. Today’s widened racks (e.g. 800mm) have a 3-inch redundant width on both sides of the 19-inch cabinet rail to cool switches or facilitate the installation of a large number of wires. The cable passes through an unsealed opening and passes through the side or top. These openings should be covered with appropriate materials to seal the voids around the cable and reduce air leakage.
Fault area 4 and 5: top and bottom of bracket mounting space (cabinet interior)
Air leaks may occur in areas above the top U and below the bottom U. Usually, these areas have some space, which varies according to the rack manufacturer. However, this area is the same as that without blind plate. This area is susceptible to hot air recirculation, and cold air from air conditioning is more likely to bypass this area.
