Description
Technical Field
The invention relates to the field of data center refrigeration, in particular to a magnetic double-suspension compressor manufacturing method, a direct double-phase-change liquid cooling system, a server cooling method and a data center year-round natural cooling method.
Background
The main components of the air conditioning system comprise a compressor, an evaporator, an expansion valve and a condenser, and the core of the working principle of the air conditioning system is reverse Carnot circulation. The compressor compresses the refrigerant to make it become high temperature and high pressure gaseous state, and the refrigerant is cooled to normal temperature and high pressure liquid through the condenser. The condensing agent at normal temperature and high pressure is converted from liquid state to gaseous state to absorb a great amount of heat in the evaporator due to pressure reduction, and the evaporator is cooled down. And blowing cold air out of the evaporator by using a fan to finish the refrigeration process.
The oil-free compressor is available in the early stages, but the dry grinding of the oil-free compressor is too serious, so that mature oil-free compressors only exist in recent years. An oilless compressor refers to a compressor that does not use lubricating oil in the compressor cylinder, and is a special compressor that does not require any lubricating oil during compression. Because no lubricating oil is in contact with a compressed air source in operation, the discharged air does not contain oil gas, and is popular with users.
The oil-free compressor can provide higher efficiency because it does not need lubricating oil; the oil-free compressor does not produce oil gas pollution, so that the influence on the environment is small; in addition, maintenance of the oil-free compressor is relatively simple since the lubricant does not need to be replaced. For a variety of reasons, oil-free compressors have been used in air conditioning applications, where such compressors are required to be capable of stable operation under a variety of environmental conditions, including high temperature and high humidity environments; in addition, since the air conditioning system needs to be continuously operated, such compressors are generally required to be capable of having high durability and reliability.
The oil-free compressor mainly comprises a motor, a compressor main body, a bearing, a sensor, a controller and the like. Oil-free compressors include both gas-suspension and magnetic suspension types. The two types of compressors belong to single-stage centrifugal compressors, the core technology adopts non-contact bearings, a high-speed permanent magnet motor and variable-frequency speed regulation, and an oil-free lubrication system can be realized, so that the oil-free centrifugal compressor has the characteristics of energy conservation, high efficiency, low noise, oil-free pollution and the like. However, their non-contact bearing types are different. The magnetic suspension compressor uses a magnetic suspension bearing, and the air suspension compressor uses an air suspension bearing; both bearings can realize that the rotor floats when running, and no mechanical contact and lubrication are needed, so that the oil-free compressor can run under the condition of no mechanical contact, and theoretically, the heat and abrasion caused by friction are avoided, and the running efficiency and the service life of equipment are improved.
However, the existing oil-free compressors still have great problems:
1. wherein the magnetic suspension oil-free compressor floats the bearing by magnetic force. The working principle of the compressor is as follows: the stator is made into an electromagnet, and a permanent magnet sheet is grooved and embedded on the outer surface of the rotor; when the rotor rotates, the magnetic repulsion forces of the stator and the rotor suspend the rotor. Magnetic suspension is small in magnetic force, unbalanced force is caused by the exhaust of a compressor, so that the compressor is swung, equipment cost is high, and the existing equipment is used for detecting the position and speed of a rotor through peripheral probes (sensors); if the rotor is disturbed, the sensor transmits the detected signal to the controller, the control signal can lead the power amplifier to generate control current, and the control current can control magnetic force, so that the rotor can be stably kept at a balance position and cannot swing, and besides the problem that accurate magnetic suspension control is troublesome, the magnetic suspension cost is higher than that of air suspension, and therefore, the magnetic suspension control device is not more used in the market.
2. The air suspension is to float the bearing by adopting high-pressure gas of a refrigerant, namely, the bearing is floated by adopting high-pressure liquid refrigerant/gas refrigerant, and the equipment is dry-ground when started and stopped because the high-pressure refrigerant is needed for the air suspension and the high-pressure refrigerant is not needed when the equipment is not started. The working principle of the air suspension bearing relates to static pressure and dynamic pressure, namely one static pressure and one dynamic pressure (namely dynamic and static);
the dynamic pressure is not generated, and the dynamic pressure is not generated, so that the dynamic pressure is generated in the dynamic pressure during the starting and stopping time, and the dynamic pressure is generated during the starting stage from the slow dry grinding, and then the bearing slowly floats up;
the static pressure is provided by a small fluorine pump, so that a high-pressure gas is provided for the compressor, the bearing floats, and the bearing is started after the bearing floats, so that dry grinding is reduced; however, the fluorine pump cannot contain oil, because the fluorine pump contains oil, the refrigerant is mixed with the oil, the oil can block the small holes in the bearing, so the whole system cannot contain the oil, the fluorine pump is oilless, but oilless, and the fluorine pump is dry-ground when started, so the method reduces the dry grinding of the compressor, but transfers the dry grinding to the fluorine pump. This problem is not a concern in the industry, simply because the current fluorine pumps are inexpensive and the cost of replacing the fluorine pump afterwards is not high.
In addition, the fluorine pump is started, some refrigerants are required to be pumped out in the evaporator, but the temperatures of the refrigerants in the evaporator are relatively low, so that the refrigerants are required to be heated by electricity, and then the refrigerants are fed into the fluorine pump after being heated, so that the whole starting time is long; the oil-free compressor is used in the data center today, and the data center has a requirement on starting time and cannot be too long, because the temperature rising speed of the data center is too fast and the time is too long to meet the use requirement of the data center.
3. In any compressor, the cost is high, the precision is low, the dry grinding and the starting time are long, the existing problems exist at present, the dry grinding problems are solved, new technology at home and abroad is realized, the remanufacturing is realized by adopting a plurality of wear-resistant materials, the dry grinding is not solved well in practice, the essence is improved only compared with the traditional technology, the whole effect is not obvious, and the service life is short.
4. At present, once a bearing of the magnetic suspension or air suspension is swung, the influence on a gap is great, and the swing amplitude of the bearing cannot be controlled by a mechanical structure, otherwise, friction is generated and dry grinding occurs as long as the bearing has the mechanical structure; while the current solution is only to correct after the occurrence of the wobble, the wobble is not fundamentally solved.
There is also a new direction: data center-! Data center, abbreviated IDC in english, i.e. Internet Data Center (internet data center). In terms of function, the data center is a very large-sized machine room, and a plurality of servers are arranged in the data center and are specially used for centralized management (storage, calculation and exchange) of data. A data center is a facility specifically designed to store, manage, and process large-scale data. It is typically comprised of a multitude of servers, network devices, storage systems, and other necessary hardware and software. According to the statistics of the industry institutions, the global data center processed data flow reaches up to 15.3ZB (1 ZB approximately 10 hundred million TB) in 2020, and the data center processed data flow accounts for 99.35% of the global total flow. That is, almost all internet data is not processed by the data center. The primary function of the data center is to provide reliable computing and storage capabilities to meet the needs of individuals, organizations and businesses. They carry many important tasks including hosting websites, applications, databases, cloud services, and big data analytics. In a data center, servers are core components that provide computing power and storage space. These servers are organized into clusters or collections for load balancing and high availability. The servers are connected through network equipment to form a high-speed internal network for data transmission and communication. Data centers are typically monitored, transported, and managed by specialized technical teams; they are responsible for ensuring proper operation of servers and network devices, performing fault diagnosis and repair, and managing resource allocation and capacity planning. With the rapid development of cloud computing and big data, data centers are becoming more and more important. Large internet companies, financial institutions, telecommunication providers, scientific institutions, and the like all build and operate their own data centers to meet the ever-increasing computing and storage requirements.
If the heat dissipation of the server of the data center is insufficient, the server is easy to overheat in a high-temperature environment, so that the performance of a processor and other hardware components is reduced, and the normal running speed and response time of the server are further influenced; and overheated servers are prone to system crashes and outages, and have serious consequences such as data loss and service interruption …, server cooling of data centers is a great prerequisite in which it is important. At present, the aim of heat dissipation is achieved by blowing air conditioner to the data center; however, a great cost is that the electric power consumption is very huge, so that the air conditioner is applied to the data center, and for better energy saving, the only method is to pursue natural cooling, but the common knowledge of the air conditioner industry is that: natural cooling is realized in winter, and the place of the data center is more advantageous in northern areas than in southern areas of China, because the time of being in low-temperature weather in one year in the northern areas is longer than in the south areas; however, although natural cooling can be used for energy saving purposes, there are still a number of serious problems, at least as follows:
at present, the natural cooling design is prepared for winter; the cooling mode of the server is that the evaporator of the air conditioner is used for directly blowing air, and the blown cold air is used for cooling, so that the efficiency is very low; based on the original problem of low efficiency, 3M company makes new improvement, firstly, a large placing box is added, a server is placed in the placing box, fluoridized liquid is added in the placing box, the placing box is provided with a plate heat exchanger, so that an air conditioner is connected with the plate heat exchanger for heat exchange, the temperature of fluoridized liquid in the placing box is reduced, and the temperature of the server is reduced; this solution has improved efficiency compared to conventional evaporator blowing, but the efficiency through heat exchange is poor; the method comprises the following steps: the plate heat exchanger performs first heat exchange with the air conditioner, (2) the plate heat exchanger cools the fluoride liquid in the placing box, and then the placing box performs second cooling on the server, (3) the heat conductivity is low, and the efficiency is not obviously improved; (4) The middle is converted for a plurality of times, so that a lot of energy is lost, and the energy is not broken through by the latest technology of ceilings in the industry. (5) In addition, the existing scheme of the 3M company has the problem of high equipment cost.
