Network Cabinet Dimensions

IDC cabinet? 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 12kW or more.

Common cabinet colors are white, black and gray. (Among them, there are many types, such as orange pattern, fine sand pattern, etc.); the cabinets are divided according to the material, there are aluminum profile cabinets, cold-rolled steel plate cabinets, and hot-rolled steel plate cabinets; according to the processing technology, there are 90% off profiles Cabinets and 16-fold cabinets, etc.

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 1202mm, so that there is enough space for installation and maintenance. The IDC cabinet, the equipment entering the computer room in stages and the relative position reserved for 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.

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, IDC cabinet, its 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. IDC cabinets have improved labor productivity and network maintenance levels, so as to achieve the transformation of the computer room from manned to few people and then to unattended. This can effectively It promoted the modernization of computer room maintenance and played a positive role. Integrated smart cabinet? The heat load of the computer room mainly comes from two aspects: one is the heat generated inside the computer room, the IDC cabinet, 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.
