Detailed Description
With the rapid development of data centers, the data centers have shorter and shorter requirements on construction periods and higher requirements on energy conservation. A large number of server racks are stored in the data center, and the servers generate a large amount of heat when kept in a working state for a long time. In order to ensure the normal operation of the server, a cooling system is required to cool the server.
The server cabinet is a liquid cooling cabinet. The cooling system comprises a liquid cooling plate system, an air cooling auxiliary cooling system and a cold supplementing system. The liquid cooling cold plate system dissipates heat for the flat part of the server, and the liquid cooling cold plate is laid on the flat part (such as a processor and other components) of the server and connected with the cooling tower through the liquid cooling circulating pump. The liquid cooling circulating pump conveys a cooling working medium (the temperature of the cooling working medium is generally consistent with the temperature of the outdoor wet bulb) to the liquid cooling plate, and the flat part of the server is cooled.
The air-cooling auxiliary cooling system is used for radiating and cooling the special-shaped part (the part on which the liquid-cooling cold plate is difficult to lay due to uneven surface of the server) of the server, an air-liquid heat exchanger is arranged on the liquid-cooling cabinet, and the air-liquid heat exchanger is connected with the cooling tower through an auxiliary cooling circulating pump. When the outdoor temperature is low (for example, the outdoor wet bulb temperature is not higher than 24 ℃), the cooling working medium is sent to the air-liquid heat exchanger through the auxiliary cooling circulating pump to carry out heat exchange between air and the cooling working medium, and the cold air after heat exchange dissipates heat for the special-shaped part of the server.
Because the air-liquid heat exchanger is arranged on the liquid cooling machine cabinet, the area of the heat exchange surface of the air-liquid heat exchanger is limited by the size of the liquid cooling machine cabinet, and the heat dissipation efficiency of the air-cooling auxiliary cooling system is influenced. Therefore, when the outdoor temperature is high (for example, the outdoor wet bulb temperature is higher than 24 ℃), a water chilling unit of the cold compensation system needs to be started, the cooling working medium is cooled to a preset temperature (for example, 28 ℃) through mechanical refrigeration (for example, compressor refrigeration), and then the cooling working medium is sent to the air-liquid heat exchanger for heat exchange, so that the heat dissipation effect on the server is ensured.

The construction mode of the cooling system is the construction in the form of engineering projects, and the cooling system has the advantages of multiple construction links, long period, high cost and low land utilization rate. In addition, the cooling working medium needs to enter a liquid cooling plate on a heat load of the liquid cooling cabinet to complete liquid cooling circulation, and the liquid cooling loop has high requirement on the cleanliness of the cooling working medium. And the field installation environment is severe, and pipelines matched with the cooling system need to be welded on site, so that impurities are easy to enter the cooling tower and the pipelines. In addition, when the outdoor temperature of the air-cooled auxiliary cooling system is high, especially in an area with high outdoor temperature, the auxiliary cooling system needs to be started to reduce the cooling working medium to the required temperature, and mechanical refrigeration affects the energy efficiency (PUE for short) of the prefabricated liquid-cooled data center.

The server provides computing or application services to other clients (e.g., terminals or devices such as smartphones, personal computers, etc.) in the network. The server has high-speed processor computing capacity, long-time reliable operation, strong input/output external data throughput capacity and better expansibility. It is to be understood that the present application is not limited to the thermal load 87 being a server, but may be other devices.
The auxiliary cooling device 73 is used to dissipate heat from the profiled portion of the heat load 87. The heat generated when the thermal load 87 operates is radiated into the communication container 81, so that the temperature of the air inside the communication container 81 is increased to form hot air. The auxiliary cooling device 73 is provided with an air inlet (not shown) and an air outlet (not shown). The air inlet of the auxiliary cooling device 73 and the communication container 81 form a heat channel through a pipe to introduce hot air (hot wind) in the communication container 81. An air outlet of the auxiliary cooling device 73 is connected with the communication container 81 through a pipeline to form a cold channel so as to convey cold air (cold air) cooled by the auxiliary cooling device 73 into the communication container 81. The hot air in the communication container 81 enters the auxiliary cooling device 73 through the air inlet of the auxiliary cooling device 73, the first cooling working medium in the auxiliary cooling device 73 is heated after heat exchange with the hot air, and the heated first cooling working medium returns to the first cooling tower 532 to be cooled and enters a new cycle. The hot air is cooled by the cooling medium in the auxiliary cooling device 73 to form cold air. The cold air returns to the communication container 81 through the cold channel, so that the auxiliary cooling device 73 can perform blowing heat dissipation on the heat load 87. It should be noted that the hot air and the cold air are only relative, and the temperature of the hot air may be higher than that of the cold air. It is to be understood that the present application is not limited to the connection manner between the auxiliary cooling device 73 and the communication module 80.

After the first cooling working medium passes through the auxiliary cooling device 73, the temperature of the auxiliary cooling device 73 is higher due to more absorbed heat, so that the auxiliary cooling device 73 forms a high-temperature air wall.
For example, when the extreme outdoor wet bulb temperature is 31 ℃, the temperature of the first cooling medium of the first cooling tower 532 is 35 ℃, the temperature of the first cooling medium in the auxiliary cooling device 73 is 35 ℃, the temperature of the inlet air of the auxiliary cooling device 73 is 45 ℃, the temperature of the cold air cooled by the auxiliary cooling device 73 is 37 ℃ (that is, the temperature of the outlet air can be kept at 37 ℃), and the temperature of the cold channel is maintained at 37 ℃ so as to dissipate heat of the heat load 87 in the liquid cooling cabinet 83 in the communication container 81.
Because the heat exchange area of the auxiliary cooling device 73 is increased, when the outdoor environment temperature is higher, the mechanical refrigeration of the first cooling medium in the first cooling tower 532 is not needed by the cold water unit, which is equivalent to that the auxiliary cooling device 73 adopts a full natural cooling mode, so that the structures of the cooling system 101 and the prefabricated liquid cooling data center 100 are simplified, and the occupied areas of the cooling system 101 and the prefabricated liquid cooling data center 100 are reduced. Compared with the related art, as the prefabricated liquid cooling data center 100 is not provided with a water chilling unit for cold supplement, the investment cost (capital extension, Capex for short) is reduced by 12%, the marketing period of the product is shortened by about 72%, and the PUE can be reduced from 1.18 to 1.15.

The power device 93 is used for supplying power to the cold source module 50, the auxiliary cold module 70 and the communication module 80. For example, the power device 93 is electrically connected to the thermal load 87 in the liquid-cooled cabinet 83 and the network devices of the network cabinet 85 to supply power to the thermal load 87 and the network devices. The power equipment 93 includes, but is not limited to, transformers, lithium-ion electrical cabinets, power distribution cabinets, Uninterruptible Power Supplies (UPS), liquid-cooled cabinet power boxes, and the like.
