Embodiment Construction
[0032] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
[0033] figure 1 A flow chart showing a liquid leakage early warning method for a liquid cooling cycle system according to an exemplary embodiment of the present invention. Here, as an example, the liquid cooling circulation system may be various types of liquid cooling circulation systems such as a water cooling circulation system and an oil cooling circulation system. The working principle of the liquid cooling circulation system can be understood as: the liquid in the circulation pipeline flows through the cooling object to absorb heat and then flows through the low-temperature environment to dissipate heat, completing a process of heat transfer. The cooling objects ...

The invention relates to a liquid leakage early warning method and device for a liquid-cooling circulation system. The method includes the following steps that: (A) the outlet hydraulic pressure values of the liquid-cooling circulation system which are used for liquid leakage analysis and acquired at a plurality of time points are obtained; (B) the obtained outlet hydraulic pressure values are sequenced into a time sequence according to the sequential order of the acquisition time; (C) time sequence smoothing is performed on the values in the time sequence, so that a processed time sequence can be obtained; (D) whether the decreasing trend of the values in the processed time sequence assumes a preset decreasing trend is determined; and (E) when it is determined that the decreasing trend ofthe values in the processed time sequence assumes the preset decreasing trend, it is determined that liquid leakage occurs in the liquid-cooling circulation system. With the method and device of theinvention adopted, early warning against the liquid leakage condition of the liquid-cooling circulation system can be performed.
Description
technical field [0001] The present invention generally relates to the technical field of liquid cooling circulation systems, and more specifically relates to a liquid leakage early warning method and device for liquid cooling circulation systems. Background technique [0002] At present, as a mature heat dissipation technology, liquid cooling has been widely used in industrial ways. A typical liquid cooling circulation system must have the following components: liquid cooling block, circulating fluid, water pump, pipeline and water tank or heat exchanger. Due to the complexity of the on-site process layout of the liquid-cooled circulation system and the loss of the system itself in regular use, liquid leakage is the most common problem in the liquid-cooled circulation system. [0003] The application of liquid leakage alarm in the existing industry is mainly through the installation of hardware detection devices, based on the fact that the pressure of the liquid cooling cyc...
