Background

With the rapid development of supercomputer technology and the emergence of rack-mounted and blade servers, server cabinets with high heat flux density are widely applied in the supercomputer field, and the high density and the low density of the servers are mixed for use, so that the heat density of the servers is unbalanced, and the imbalance of heat in a machine room is caused. The traditional air conditioner can not meet the requirement of heat dissipation by centralized air supply. Over the past decade, server density has increased on average by about ten times, and in the supercomputer field, cooling power consumption has taken up a considerable proportion of the overall power consumption. As energy prices have risen, the cooling problem has become an unavoidable problem in all data centers.

A cabinet is a freestanding or self-supporting enclosure for housing electrical or electronic equipment. The cabinet is generally provided with a cabinet door, a detachable or non-detachable side plate and a back plate, is an indispensable component in electrical equipment and is a carrier of electrical control equipment. Typically made of cold rolled steel sheet or alloy. Can provide the protection functions of water resistance, dust prevention, electromagnetic interference resistance and the like for the storage equipment. Cabinets are generally classified into server cabinets, network cabinets, console cabinets, and the like.

The number of the server cabinets is increasing, the cabinets are arranged more and more densely, and cold air blown out by a traditional cooling air-conditioning system cannot fully flow to all places of a machine room, so that hot air is easily concentrated in a specific area to form a hot dead zone, and the instability of the server cabinet system can be caused naturally. And traditional rack simple structure, the radiating effect is relatively poor, only relies on indoor air conditioner, can only adjust indoor bulk temperature, is difficult to effectively giving off the inside heat of rack to it is higher to lead to the inside long-term back temperature that uses of rack, has certain danger.
