Description

Self-cooling cabinet for electronic equipment

technical field

The present invention relates to the technical fields of electrical appliances, communications or computers, and in particular to a self-cooling cabinet for electronic equipment.

Background technique

With the emergence of more and more data centers in my country, the challenges of energy saving and consumption reduction of cabinets and servers or transformation and capacity expansion put forward new requirements for the power density and installation density of the computer room. Numerous IDC computer rooms and data centers have experienced a sharp increase in heat generation per unit area of a single rack or a local rack, which has led to the occurrence of high heat density phenomena in which local "heating" occurs in computer rooms and cabinets. At present, the data center and the server cabinets and the computer room need to be equipped with a cooling system to dissipate heat. For some small data centers, when a small number of server cabinets need to be arranged, the traditional cooling mode requires a long cycle and has low efficiency.

The total number of data centers in the world exceeds 3 million, and the power consumption accounts for 1.1%-1.5% of the world's total power consumption. my country's data centers are developing rapidly, with a total of more than 400,000, and the annual power consumption exceeds the electricity consumption of the whole society. 1.5%, and the PUE of most data centers is still generally greater than 2.2, which is far behind the international advanced level. The IT equipment in the data center needs to be cooled around the clock. Usually, precision air conditioners or chillers are used for cooling in the data center. With the rapid development of the data center, the annual power consumption of the data center is increasing at a rate of 20%. Among them, the data center The energy consumption of central air conditioners accounts for 35%-45%, and the proportion of some computer room air conditioners is even higher. The existing cooling method of the data center is usually to cool the environment first and then cool the equipment. For example, in GB50174-2008 "Code for Design of Electronic Information System Computer Room", Class A and B computer rooms require an ambient temperature of 23°C ± 1°C, while the actual data center server The temperature in the cabinet can reach above 45°C. If the concept of direct cooling equipment is adopted, it can effectively reduce the waste of cooling load, especially according to different regions and seasonal periodic changes, combined with the combination of natural cold source and air-cooled chiller cooling technology, adopting the back Plate heat pipes or a combination of heat pipes and heat pumps cool server cabinets and can completely replace precision air conditioners. On the one hand, they can effectively reduce PUE and improve energy efficiency utilization. On the other hand, they can effectively solve local hot spots caused by unreasonable airflow organization of precision air conditioners. At the same time, through the complete replacement of air-conditioning units, the space utilization rate of the computer room can be effectively improved, and more server cabinets can be arranged, thereby effectively improving economic benefits and land-saving effects.
