Cold aisle in the computer room? The free flow intelligent integrated monitoring cabinet is a comprehensive integrated control equipment specially used for the toll road ETC gantry system. This product integrates the integrated cabinet body, east ring monitoring, core control host and UPS uninterruptible power supply. It can meet the function and protection requirements of the front-end core equipment of free flow charging.

The type of board, coating material, and processing technology determine the stability of the cabinet. Generally, its length specifications are 600, 800mm, width specifications are 600, 800, 1000mm, and height specifications are 42U, 36U, 24U. Most of the cabinets used in the early days were made of castings or angle steels connected or welded into the cabinet frame by screws, rivets, and then made of cover plates (doors) made of thin steel plates. This kind of cabinet is bulky, heavy, and crude in shape, and has been eliminated.
With the use of transistors and integrated circuits and the miniaturization of various components, the structure of the cabinet is also developing in the direction of miniaturization and building blocks. The cabinet has developed from the whole panel structure in the past to a box and plug-in structure with a certain size series. There are two types of assembly and arrangement of subracks and plug-ins: horizontal arrangement and vertical arrangement. Cabinet materials generally use thin steel plates, steel profiles of various cross-sectional shapes, aluminum profiles, and various engineering plastics. The frame of the cabinet is not only welded and screwed, but also bonded.
Server hosts, storage devices, and server cabinets should be arranged in partitions. Maintenance space should be reserved for hosts, storage devices, server cabinets, UPSs, air conditioners and other equipment according to product requirements, and the maintenance distance of adjacent equipment is allowed to overlap. The clear width of the aisle between the equipment should not be less than 1203mm, so that there is enough space for installation and maintenance. The cold aisle of the computer room, the equipment entering the computer room in stages and the relative position of the reserved expansion equipment must not only conform to the process flow of the computer system, but also facilitate the entry and placement of expansion equipment and the connection of cables in the future.

In the daily operation and maintenance process of the data center, it is not only necessary to ensure the safe and reliable operation of the equipment in the data center, but also to reasonably control the energy consumption. Therefore, during the operation of the air conditioning system, appropriate adjustments should be made according to the dynamic environment monitoring. If the temperature is set too low, the energy consumption will increase significantly.
The cold aisle of the computer room, therefore, in our daily work, the temperature and humidity setting, as long as it is within the A-level standard range, the cooling capacity and the heat generation balance are well controlled, and the ambient temperature and humidity in the computer room are controlled by controlling the air supply volume. The cold aisle in the computer room avoids the problem of wind short circuit. At the same time, we must also pay attention to the problem of uneven temperature distribution.
Only by properly solving the problem of air distribution can the problem of uneven temperature be completely eliminated. idc managed cabinet? The air-conditioning load of the computer room mainly comes from the heat generated by computer equipment, external equipment and equipment in the computer room, accounting for more than 80% of the total heat, followed by lighting heat, conduction heat, radiant heat, etc. These calculation methods are different from those of general air-conditioned rooms. Load calculations are the same.
Computer manufacturers can generally provide specific values for the heat generated by the equipment. Otherwise, calculate its calorific value according to the power consumption of the computer. The total power of various equipment in the computer room should be based on the maximum power consumption of the equipment in the computer room, but the power consumption is not all converted into heat, so it must be corrected with the above three coefficients, and these coefficients are related to the computer system. It is related to the structure, function, use, working status and electronic components used. The total coefficient is generally between 0.6 and 0.8 as well.
