For example, as shown in fig. 1, the computer room may include a plurality of rows of racks, i.e., 1 st to 8 th rows of racks. A channel between the 1 st row cabinet and the 2 nd row cabinet, a channel between the 3 rd row cabinet and the 4 th row cabinet, a channel between the 5 th row cabinet and the 6 th row cabinet, and a channel between the 7 th row cabinet and the 8 th row cabinet can be cold air channels; the channel between the 2 nd row cabinet and the 3 rd row cabinet, the channel between the 4 th row cabinet and the 5 th row cabinet, and the channel between the 6 th row cabinet and the 7 th row cabinet can be hot air channels. That is, in the embodiment of the present application, the cold air channel and the hot air channel are arranged side by side in a crossed manner. Therefore, the heat exchange between the cold air generated by the refrigerating system and the heat generated by the equipment in the cabinet can be fully carried out.

As shown in fig. 1, a refrigeration system provided by the embodiment of the present application may include a plurality of surface cooling units, a plurality of airflow power devices, and a plurality of cooling cycles.

The airflow power device can flow air inside the machine room. The airflow power devices can be arranged at two ends of the hot air pipeline.

Wherein, the surface cooling unit can also be called as a surface cooling tail end and a surface cooler. The surface cooling unit may be used to provide cooling air. The plurality of surface cooling units can be arranged below the cold air channel and face upwards. So, the cold air that the surface cooler produced can directly blow the rack, need not other transmission pipelines, has shortened the air supply route. Therefore, the refrigeration system provided by the embodiment of the application has higher refrigeration efficiency.

Wherein, the cooling circulation device can be used for providing cooling liquid for the surface cooling unit. The cooling circulation device can comprise a liquid separating groove and a liquid collecting groove. The liquid dividing tank can be used for providing low-temperature cooling liquid. The sump may be used to contain the returning high temperature coolant. The liquid separating groove can be communicated with liquid inlet pipelines of a plurality of surface cooling units. The liquid collecting tank can be communicated with liquid outlet pipelines of a plurality of surface coolers.

For example, as shown in fig. 2, the circulation cooling device 1 and the circulation cooling device 2 are provided at both ends of the same cold air passage. The circulation cooling device 1 includes a liquid separation tank 1 and a liquid collection tank 1. The circulation cooling device 2 includes a liquid separation tank 2 and a liquid collection tank 2. Each surface cooling unit can comprise a plurality of groups of pipelines, and one group of pipelines can comprise a liquid inlet pipeline and a liquid outlet pipeline. The liquid inlet pipeline and the liquid outlet pipeline in the group of pipelines are communicated. For example, in fig. 2, one surface cooling unit includes 2 sets of pipes, which are a liquid inlet pipe 1 and a liquid outlet pipe 1, and a liquid inlet pipe 2 and a liquid outlet pipe 2. The liquid inlet pipeline 1 is communicated with the liquid outlet pipeline 1. The liquid inlet pipeline 2 is communicated with the liquid outlet pipeline 2.

Wherein, divide the liquid groove and communicate with the liquid inlet pipeline of a plurality of cold units of table respectively. The liquid collecting tank is respectively communicated with the liquid outlet pipelines of the surface cooling units.

For example, as shown in fig. 2, the liquid separation tank 1 is communicated with the liquid inlet pipes 1 of the plurality of surface cooling units, respectively, and the liquid separation tank 2 is communicated with the liquid inlet pipes 2 of the plurality of surface cooling units, respectively. The liquid collecting tank 1 is respectively communicated with the liquid outlet pipelines 1 of the plurality of surface cooling units, and the liquid collecting tank 2 is respectively communicated with the liquid outlet pipelines 2 of the plurality of surface cooling units. Therefore, the low-temperature cooling liquid in the liquid dividing tank can flow into the surface cooling unit through the liquid inlet pipeline, and becomes the high-temperature cooling liquid after heat exchange. The high-temperature cooling liquid flows into the liquid collecting tank through the liquid outlet pipeline.

Furthermore, the liquid separating tank and the liquid collecting tank in each cooling circulation device can be communicated. Based on the design, recycling of the cooling fluid may be included.

In one possible design, a heat exchanger may be provided inside the sump, which may be used to reduce the temperature of the coolant in the sump.

In one possible design, the cooling circuit arrangement can also be provided with a circulation pump. The circulation pump may control the flow rate of the cooling fluid. For example, the higher the operating frequency of the circulation pump, the faster the flow rate of the coolant; the lower the operating frequency of the circulation pump, the lower the flow rate of the cooling liquid.

Further, the cabinet may be provided with one or more temperature sensors. The one or more temperature sensors may be used to detect a temperature within the cabinet. The one or more temperature sensors may be in communicative connection with the circulation pump. Based on this design, the circulating pump can be according to the temperature in the rack, the operating frequency of control self.

In one possible design, as shown in fig. 2, the liquid inlet pipe and the liquid outlet pipe of each surface cooling unit are provided with control valves. For example, the liquid inlet pipeline 2 and the liquid outlet pipeline 2 are provided with control valves. The control valve can be used for controlling the flow or cut-off of the cooling liquid between the liquid separating tank 2 and the liquid collecting tank 2 and the surface cooling unit. When the control valve is in an open state, the liquid dividing and collecting tank 2 and the cooling liquid between the liquid dividing and collecting tank 2 and the surface cooling unit can flow; when the control valve is in the closed state, the coolant between the liquid scoring tank 2 and the liquid collecting tank 2 and the surface cooling unit can be cut off.

It should be noted that the liquid inlet pipe 2 and the liquid outlet pipe 2 can be used as spare pipes to ensure normal refrigeration of the refrigeration system when the liquid inlet pipe 1 and the liquid outlet pipe 1 are abnormal.

Wherein, when the liquid inlet pipeline 1 and the liquid outlet pipeline 1 are normal, the control valve can be in a closed state; when the liquid inlet pipeline 1 and the liquid outlet pipeline 1 are abnormal, the control valve can be in an opening state. Therefore, the reliability of the refrigerating system can be ensured by the arrangement of the main and standby pipelines.

In fig. 2, the liquid inlet pipe 1 and the liquid outlet pipe 1 may also be provided with control valves (not shown).

In one possible design, as shown in fig. 1, the air flow power devices may be disposed at both ends of the hot air passageway. As shown in fig. 3, the air flow power device may include a return air filter section and a centrifugal fan, among others.

Wherein, return air filter section can be used to filter the air in the computer lab for the dust in the adsorbed air. Thus, the air in the machine room can be purified. Centrifugal fans may be used to drive the flow of air within the machine room.

In one possible design, as shown in fig. 3, the floor in the machine room may be hollowed out, and the surface cooling unit and the centrifugal fan may be disposed below the floor. The return air filter section may be disposed above the floor.

In one example, when the refrigeration system is in normal operation, cold air generated by the surface cooling unit can enter the cold air channel to exchange heat with hot air generated by the cabinet, and the cold air is converted into hot air. The hot air enters the hot air channel under the action of the centrifugal fan. Then, heat exchange is performed again with the surface cooling unit through the overhead layer. Therefore, the temperature in the machine room can be reduced.

In this application, "communication" means communication, and a coolant can flow between the connected devices.
