Description

Technical Field

[0001] This application belongs to the field of server air cooling technology, and particularly relates to a server cooling device. Background Technology

[0002] Air cooling is a type of cooling method that uses air as a medium to cool the object that needs to be cooled. This usually involves increasing the surface area of ​​the object, increasing the rate at which air flows over the object per unit time, or a combination of both. The former can be achieved by adding heat sinks to the surface of the object, usually by hanging the heat sinks on the outside of the object or fixing them to the object to make heat dissipation more efficient. The latter can use fans (fans) to enhance ventilation and improve the cooling effect. In most cases, adding heat sinks can greatly improve cooling efficiency.

[0003] Existing server air-cooling technology simply uses two external fans, which has a very small heat dissipation effect and is not conducive to stable server cooling. In addition, there is room for improvement in terms of intelligent temperature control coordination and ease of maintenance.

[0028] A protective frame 23 is fixedly connected to the inner wall of the base 1. The protective frame 23 is located above the expansion tank 9 and serves to protect the expansion tank 9 from collisions.

[0031] The working principle of this utility model is as follows: In use, firstly, two pump bodies 6 are electrically connected via wires. Then, the power provided by the two pump bodies 6 draws water from inside the water supply tank 5 into the connecting pipe 8. Before this, two check valves 7 prevent backflow. The water then enters the plate-fin heat exchanger 4 for heat dissipation. With the assistance of two fans 18, the temperature can be quickly lowered. Then, the expansion tank 9 buffers pressure fluctuations and provides partial water supply. The buffer pipe 10 is fixedly connected to the expansion tank 9 to automatically regulate the pressure inside the water supply tank 5. Using the safety valve and pressure relief pipe 11 connected externally to the buffer pipe 10, the pressure can be adjusted when a certain value is reached. The device automatically releases pressure after reaching a certain value to avoid excessive pressure and ensure the safety of equipment use. Utilizing flow meter 13 and pressure sensor 24, it can monitor the internal conditions of the pipeline in real time, enabling real-time monitoring of equipment operation. The results are then displayed on the control screen 16. This rack-mounted cooling unit for servers has a rated cooling capacity of 8 kilowatts.

The system features comprehensive real-time monitoring of operating parameters and redundant communication interfaces, supporting standard communication interfaces and defaulting to Modbus RTU and Modbus TCP / IP protocols, making the device more intelligent.
