Communication power supply? The traditional data center adopts the air supply method under the floor. Each cabinet is equipped with 1-2 air outlets. The air output of each air outlet is 500-800m3/h. Calculated based on the temperature difference between the supply and return air of 12°C, the maximum cooling capacity of a single cabinet air conditioner is 3kw-5kw cannot solve the heat dissipation problem of high-density servers, and it is difficult to meet the heat dissipation of high-density cabinets with a single cabinet above 5kW.
The modular data center adopts the scheme of horizontal air supply and closed cold/hot aisle of the inter-row air conditioner. The air supply and return air are all in a small range, and the airflow organization does not interfere with each other. Several cabinets are considered as a cooling unit, which can greatly improve the cooling efficiency. The inter-row air conditioner can directly send the cooling capacity to the server cabinet through point-to-point precise cooling, which ensures the support for the cooling capacity of the high-density data center and supports the power of a single cabinet. Up to 10kW or more.

- The cabinet can be divided into two basic structures: profiles and thin plates according to the load-bearing, materials and manufacturing processes of the components. ① Profile structure cabinet: There are two types of steel profile cabinets and aluminum profile cabinets. The steel profile cabinet is composed of special-shaped seamless steel pipes as columns. The rigidity and strength of this cabinet is good for heavy equipment. The aluminum profile cabinet composed of aluminum alloy profiles has certain rigidity and strength, and is suitable for general or light equipment. This kind of cabinet is light in weight, less in processing amount, beautiful in appearance, and is widely used. ②Thin plate structure cabinet: the whole plate type cabinet, the side plate is formed by bending a whole piece of steel plate. This kind of cabinet has good rigidity and strength, and is suitable for heavy or general equipment. But because the side panels cannot be disassembled, it is inconvenient to assemble and maintain. The structure of the bent plate column cabinet is similar to that of the profile cabinet, and the column is made of bent steel plates. This kind of cabinet has a certain rigidity and strength, and is suitable for general equipment.
Proper layout of rack space is also very important to ensure proper temperature and enough cool air in the rack. The goal of proper rack layout is to control air circulation, that is, to avoid mixing of cold air with hot air before it reaches the equipment intakes. The solution to this problem has a wide range of applications. Unreasonable equipment installation location, especially the installation location of high power density equipment, may significantly increase the working pressure of the computer room. High load density clusters occur when high load density, high power servers are combined into one or more cabinets. This situation can cause a hot spot in the data room and require the operator to take appropriate action, such as lowering the air temperature set point.

The power environment monitoring system in the data room is a computer network composed of a complete set of computer network, database, communication, automatic control and new sensor technology. It is a computer technology-based, centralized management and monitoring automation system. , intelligent and high-efficiency technical means, communication power supply, the monitoring object is the power equipment in the computer room and the environment of the computer room.
The construction of a monitoring system can make full use of human resources, as well as strengthen the maintenance of stable operation of equipment and the safety of the computer room, communication power supply, improve labor productivity and network maintenance level, so as to achieve the transformation of the computer room from manned to few people and then to unattended, which can effectively It promoted the modernization of computer room maintenance and played a positive role.
Vertical server cabinet? The heat load of the computer room mainly comes from two aspects: one is the heat generated inside the computer room, the communication power supply, which includes: the heat generated by the indoor computer and external equipment, the heat generated by the auxiliary facilities of the computer room and the equipment in the computer room (electric heating, steam water temperature and others) heating stuff). The calorific value is large in sensible heat and small in latent heat; heating of lighting (sensible heat); heating of staff (small in sensible heat and large in latent heat); heat generated by evaporation and condensation of water (latent heat).
The second is the heat generated outside the computer room, which includes: conduction heat, heat intruded through the building body, such as heat (sensible heat) introduced into the computer room from walls, roofs, partitions and ground; radiant heat (also called radiant heat) , the heat (sensible heat) directly entering the room from the glass window due to sunlight; the heat generated by convection, the heat (sensible heat, latent heat) generated by the high-temperature outdoor air (including water vapor) intruding from the gaps such as doors and windows; in order to make The heat generated by the fresh air (including sensible heat and latent heat) introduced by indoor staff to reduce fatigue and benefit human health.
