Description

Technical Field

[0001] The present invention relates to the technical field of liquid cooling systems, and particularly to a safety protection method and system applied to an immersion liquid cooling system. Background Art

[0002] With the continuous increase in the power density of electronic devices, especially data center servers, high-performance computing devices, and 5G base stations, traditional air-cooling technologies have been difficult to meet the heat dissipation requirements. The heat generated by these high-density devices far exceeds the processing capacity of air-cooling systems, resulting in overheating of the devices, affecting performance and even causing damage. Immersion liquid cooling technology can directly transfer heat from the heat source to the coolant, thus providing a more efficient heat dissipation solution. An immersion liquid cooling system immerses all parts of the server in the coolant for cooling. The overall form of the cabinet is similar to a "freezer", completely changing the traditional form of the server and the computer room. Currently, there are mainly two technical paths for immersion liquid cooling technology: phase change immersion liquid cooling technology and single-phase immersion liquid cooling technology. And this technical solution adopts single-phase immersion liquid cooling technology.

[0003] Single-phase immersion liquid cooling technology completely immerses IT devices in an insulating coolant. Through the flow of the liquid, the heat of the heat-generating components is taken away, and the heat is transferred to the heat exchange system (cooling tower or dry cooler) through a heat exchanger, and the heat exchange system dissipates the heat to the outdoor environment. Compared with phase change liquid cooling technology, single-phase liquid cooling technology has core advantages such as simple operation and maintenance, stable liquid and not easy to volatilize, and low cost.

Currently, these problems still require manual means to maintain the system. Therefore, how to realize the automation and intelligence of the safety maintenance of the immersion liquid cooling system and ensure the safe and stable operation of the immersion liquid cooling system has become an important problem to be solved.

[0005] Therefore, currently, a safety protection method and system applied to an immersion liquid cooling system are provided, which can realize the automation and intelligence of the safety prevention and maintenance of the immersion liquid cooling system, is beneficial to improving the working efficiency of the immersion liquid cooling system, and improving the protection safety and stability of the immersion liquid cooling system.
