With the rapid development of the Internet, cloud computing, big data and other fields, a new generation of data center construction network, servers, storage and other infrastructure equipment further centralized, which also raises out higher requirements for the development of data centers. In the hot summer, the temperature of equipment and cabinets in the server room rises sharply. For data centers, the ambient temperature in the server room directly affects the normal work of the equipment, and heat dissipation is very important for the cabinets. So what is the inevitable connection between the environment of the server room and the micro-module cabinet? And how should the cabinet heat dissipation?
The effect of heat dissipation in the server room is closely related to the choice of cabinets and the placement of cabinets. It is easy to overlook the micro-module cabinet in question. Currently liquid-cooled (or water-cooled) cabinets are the most discussed topic, more accurately described as cabinets with liquid-cooled doors. The high density of servers is an inevitable trend in the development of data centers, and the ensuing heat dissipation problem has become increasingly serious and deserves a high degree of attention.
In the new situation, new requirements are put forward for cabinets. The new generation of data center, whether it is resource consolidation, virtualization; or green energy saving, automation and security management, are the hot spots today.
Existing data centers have rack or micro-module cabinets with a power configuration of 10A (amps), which can deploy 15 - 16 1U rackmount servers at full load. For poorer data centers, the power provisioning is just 6.8A for blade servers. The power required for a fully equipped blade server is about 10A.
The choice of different types of micro-module cabinet cooling is also different, for the high load of the server cabinet, because the equipment heat is huge, this type of cabinet front and rear doors generally use high-density mesh doors, the heat and cold air quickly exchange, can quickly reduce the cabinet temperature; general common network cabinets, because the equipment less heat, generally use glass doors or steel doors, in addition to the auxiliary cooling device (such as axial fans fans and cross-flow fans, etc.) can also effectively control the cabinet temperature.
In the green environmental protection is more and more attention today, how to effectively use refrigeration resources is also increasingly important. Common cabinets will generally use mesh panels installed in the redundant equipment installation to isolate the hot and cold air ducts, so that refrigeration resources can be used to where it is needed to prevent the waste of refrigeration resources. Some cabinets will even install insulation foam on the side panels to obtain the best insulation effect. Common cabinet cooling application scenarios are the following 3 kinds.
