A liquid-cooled heat dissipation cabinet door

technical field

The invention relates to the technical field of cabinets, in particular to a liquid-cooled and heat-dissipating cabinet door.

Background technique

With the rapid development of supercomputer technology and the emergence of rack and blade servers, server cabinets with high heat flux have been widely used in the field of supercomputers. The mixed use of high-density and low-density servers makes the heat density of servers Unbalanced, resulting in unbalanced heat in the computer room. The centralized air supply of traditional air conditioners can no longer meet the requirements of heat dissipation. In the past ten years, server density has increased by an average of about ten times. In the field of supercomputers, cooling energy consumption occupies a considerable proportion of the overall energy consumption. As energy prices continue to rise, cooling issues have become an unavoidable problem for all data centers.

A cabinet is a free-standing or self-supporting enclosure used to house electrical or electronic equipment. Cabinets are generally equipped with cabinet doors, removable or non-removable side panels and back panels. Cabinets are an indispensable part of electrical equipment and the carrier of electrical control equipment. It is generally made of cold-rolled steel plate or alloy. It can provide protection against water, dust, and electromagnetic interference for storage equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc.

The number of server cabinets is increasing, and the arrangement of cabinets is becoming more and more dense. The cold air blown out by the traditional cooling air-conditioning system cannot fully flow to all parts of the computer room, resulting in hot air tending to concentrate in specific areas, forming a thermal dead zone. It will cause instability of the server cabinet system. The traditional cabinet structure is simple and the heat dissipation effect is poor. Only the indoor air conditioner can only adjust the overall temperature of the room, and it is difficult to effectively dissipate the heat inside the cabinet. As a result, the temperature inside the cabinet will be high after long-term use, which has certain dangers. sex.
