Parallel heat radiating system of computer-room equipment

Abstract

The invention relates to a parallel heat radiating system of computer-room equipment. The parallel heat radiating system is characterized by comprising a cabinet parallel heat radiating system; the cabinet parallel heat radiating system is provided with a closed circulating pipeline which is filled with proper amount of heat exchanging medium; a cabinet heat release and condensation device and a plurality of cabinet heat absorbing and evaporating devices are connected to the pipeline; the cabinet heat-absorbing and evaporating devices are respectively arranged at the heat release points of indoor computer-room equipment; the cabinet heat release and condensation device is arranged outdoors; the cabinet heat absorbing and evaporating devices are connected to a master gas pipe via gas branch pipes; the master gas pipe is connected to the cabinet heat release and condensation device; the partial or whole gas is condensed into liquid by the cabinet heat release and condensation device, and then the liquid is sent to a master liquid pipe; the liquid in the master liquid pipe backflows to the cabinet heat absorbing and evaporating devices via liquid branch pipes; the mounting height of the cabinet heat absorbing and evaporating devices is lower than the mounting height of the cabinet heat release and condensation device. The parallel heat radiating system of the computer-room equipment, disclosed by the invention, is used for releasing the heat to the outside via the closed circulating pipeline in a manner of absorbing heat at the heat release points of a computer room, so that the temperature in the computer room does not rise and the operating environment of the computer room is guaranteed.

Description

technical field [0001] The invention relates to a parallel cooling system for equipment in a computer room. Background technique [0002] In the 1960s, with the development of communication program-controlled switching technology, the computer room environment could no longer meet the operating requirements of program-controlled switching equipment. The program-controlled computer room needed a heat removal device that could be used in various environments. Due to the influence of inherent At that time, the industry generally thought of the air-conditioning technology that had become increasingly mature at that time. The design idea of ​​computer room air-conditioning has continued to this day, and it has also entered the current market environment through continuous improvement by latecomers. [0003] Since computer room air conditioners can meet the environmental requirements of program-controlled switching equipment, the rapid development of program-controlled switching t...

AI Technical Summary

Problems solved by technology

[0004] In the 21st century, data and network services began to enter the market. Compared with program-controlled switching equipment, the calorific value of data and network equipment has exploded. In this case, the design idea of ​​continuing the heat dissipation of program-controlled switches has gradually Showing technical fatigue, it is difficult to keep up with the new technical situation, and there are some technical bottlenecks that cannot be ignored

[0005] The specific technical bottlenecks are as follows: 1. Huge energy consumption: According to incomplete statistics, the proportion of energy consumption of air conditioners in various computer rooms at the current stage is close to half of the total energy consumption of the computer room, and this part of energy consumption cannot produce any direct economic benefits It is only to ensure the operating environment of the equipment in the computer room, and indirectly generate economic benefits from the equipment in the computer room

[0006] 2. Huge volume: At present, the most exquisitely designed computer room air conditioner host, including the maintenance station, can only provide less than 20KW of sensible cooling per square meter. In the current computer room, a single cabinet (covering an area of ​​less than one square meter) It can easily reach a heating capacity of more than 20 kilowatts, that is to say, for a single cabinet (covering an area of ​​less than one square meter), it needs to be equipped with an air conditioner with a cooling capacity of more than 20 kilowatts (the computer room covers an area of ​​about 1.5 square meters)

[0007] 3. Expensive maintenance costs: Due to the large-load operation all year round, the computer room air conditioner must meet the high maintenance level while designing with high requirements. At the same time, the core technology of the computer room air conditioner belongs to the multiple nonlinear refrigeration technology. The requirements are quite high, and expensive maintenance costs must be paid to meet the stable operation of the air conditioner in the computer room

[0020] 5) Humidity intelligent control: The equipment in the computer room is basically composed of various circuit boards. The operation has high requirements on humidity. If the humidity is too low, static electricity will easily occur, and if the humidity is too high, it will cause various faults such as short circuit of the circuit board. Therefore, the air conditioner in the computer room Most of them are equipped with a dehumidification system, but the humidity configuration is often not rigorous in the configuration of the air conditioner in the computer room

[0028] To sum up, due to the continuous development of the communication industry, the heat generated by the equipment in the computer room continues to increase, resulting in various difficult problems in the original computer room cooling technology, such as huge energy consumption, uneven cooling and heating inside the computer room and other bottlenecks

In addition, the equipment in the computer room is still increasing in computing power and heat generation. In the long run, the air conditioner in the computer room will eventually be unable to meet the cooling needs of the computer room.
