Welcome to Shanghai huijue network communication equipment Co., Ltd

The demand for IT equipment in our country is on the rise

Network server cabinet? The demand for IT equipment in our country is on the rise, and the business of each data center is developing rapidly. It often happens that the existing configuration of the data center that has just been built and put into use cannot meet the demand within one or two years. The expansion of the traditional data center in the later period does not have installation or installation is very difficult. Large, resulting in repeated construction and large waste of investment.

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

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.

The IDC data room cabinet is a multi-functional and multi-professional system integration project. In addition to various equipment of the electronic computer system, there are also various environmental protection equipment, such as cold aisle systems, column cabinets, server cabinets, PDU power sockets, power Environmental monitoring system, KVM system. , Only with a reasonable planning of equipment layout can the functions of each subsystem be fully utilized, which facilitates future expansion, facilitates the management of operation and maintenance personnel, and achieves the effect of saving investment and cost.

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. Huijue network data center solution, similarly, the temperature and humidity indicators of the computer room are required to be relatively stable, and a larger circulating air volume will help stabilize the temperature and humidity indicators of the computer room.

Obviously, under the condition of a certain cooling capacity, the increase of the air volume will lead to 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. Rackmount server cabinet? 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 structure that is not in direct contact with the 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 0.8. 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.
