Welcome to Shanghai huijue network communication equipment Co., Ltd

What is data center examples?

Traditional data centers usually take months or even years from planning to construction completion, which is incompatible with the rapid replacement cycle of IT equipment. Fast and unable to adapt to the latest IT equipment development needs.

Shanghai Huijue is committed to becoming a leader in the network connection industry


The cabinet is generally made of cold-rolled steel plate or alloy to store computers and related control equipment. It can provide protection for storage equipment, shield electromagnetic interference, and arrange equipment orderly and neatly to facilitate future maintenance of equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc.

The sides of the server cabinets can be arranged without spacing, and the cabinets can be combined to facilitate the laying of strong and weak wires (cables). The distance between each row of cabinets should be in line with the floor modulus, so as to avoid filling the floor less than 300mm before and after the cabinets. The cold aisle in the computer room is closed. When placing servers with high heat generation such as IBM690, 670 and other server cabinets, the clear distance between the front of the cabinets should not be less than 3.lm, so as not to affect the heat dissipation of the equipment due to high heat density. For server rooms with a lot of equipment, it is recommended to use the head cabinet method, so that the integrated wiring cables are collected in the head cabinet instead of the core cabinet to save twisted pairs and optical fibers. At the same time, it is convenient to use secondary network switching equipment, and it is also convenient for installation and use A KVM system in a row of cabinets.

Compared with the comfort air conditioner with the same cooling capacity, the circulating air volume of the special air conditioner for the computer room is about twice as large, and the corresponding enthalpy difference is only half. The special air conditioner for the computer room usually does not need dehumidification during operation, and the large circulating air volume will make the unit in the air. When operating above the dew point, it is not necessary to cool the air below the dew point in order to cope with the humidity load like a comfort air conditioner. Therefore, the unit can improve the thermal efficiency of the unit operation by increasing the evaporation temperature of the refrigerant, thereby improving the economy of operation. The cold aisle in the computer room is closed. Similarly, the temperature and humidity indicators in the computer room are required to be relatively stable. A larger circulating air volume will help stabilize the temperature and humidity indicators in the computer room. Obviously, under the condition of a certain cooling capacity, the increase in the air volume will lead to a decrease in the enthalpy difference. Therefore, usually the unit can only operate under the condition of a relatively high sensible heat ratio, which is just in line with the load characteristics of the machine room. Is the cold aisle in the computer room closed? The conduction heat that enters the computer room through the roof, walls, partitions and other enclosure structures of the computer room is a quantity related to the season, time, geographical location and the angle of the sun. Therefore, it is a very complicated problem to accurately obtain such a quantity. When calculating the enclosure structures that are not in direct contact with outdoor air, such as partitions, the temperature difference between indoor and outdoor calculations should be multiplied by the correction coefficient, and its value is usually 0.4 to 0.7. When the glass is irradiated by sunlight, part of it is reflected, part of it is absorbed by the glass, and the rest passes through the glass into the computer room and is converted into heat. The heat absorbed by the glass increases the temperature of the glass, and part of it enters the machine room through convection and becomes a heat load. The intensity of solar radiation heat q varies with latitude, season and time, and varies with the angle of solar radiation. For specific values, please refer to local weather information.
