Description

Liquid leakage detection module Technical Field The invention relates to the technical field of leakage detection, in particular to a leakage detection module. Background In a liquid cooling heat dissipation system, a liquid cooling device conveys cooling liquid through a closed pipeline to efficiently take away heat generated in the running process of equipment, and compared with traditional air cooling heat dissipation, the liquid cooling heat dissipation system has the advantages of high heat dissipation efficiency, low noise, low energy consumption and the like, and has become a main stream technical scheme for heat dissipation of high-density and high-power electronic equipment. The pipeline joints between the pipelines of the liquid cooling system and between the pipelines and the liquid cooling device are formed through joints, and the joint is used as a splicing joint of the liquid cooling system, is affected by factors such as assembly precision, pipeline vibration, medium pressure fluctuation, material aging and the like, and is a high-emission area for leakage of cooling liquid. Once the pipeline joint is leaked, the heat dissipation efficiency of the liquid cooling system is greatly reduced, the heat dissipation requirement of equipment cannot be met, the problems of short circuit, corrosion of metal parts, insulation performance failure and the like of peripheral electrical equipment can be possibly caused, and even serious safety accidents such as equipment downtime and fire disaster can be caused, so that the real-time and reliable liquid leakage detection of the liquid cooling pipeline joint is a core link of the safety protection of the liquid cooling system. The existing leakage detection scheme mainly comprises two modes, namely a leakage sensing circuit board is arranged at the bottom of a connecting end of a pipeline, the scheme is required to be specially designed according to the plane structures of different liquid cooling devices, the adaptability is extremely poor, when the size of the pipeline or the structure of the device is changed, the sensing circuit board cannot be reused, the use cost is increased, a large number of liquid cooling detection lines are wound on the pipeline, in order to ensure the detection stability, multiple winding operations are required during construction, the steps are complicated, the construction efficiency is low, the winding density is difficult to accurately control, and the problems of detection dead zones or resource waste are easy to occur. The suitability and construction convenience can not be considered in the above two schemes, and the leakage detection requirement of the liquid cooling pipeline joints with different specifications is difficult to meet. In addition, the detection principles of the two existing schemes are based on resistance change of conductive liquid, and the detection electrode cannot distinguish pipeline condensation generated by high environmental humidity, water vapor in air and cooling liquid truly leaked from a pipeline. In the high humidity scenes such as the south plum rains, the cold channels of the data center, the underground machine room, the outdoor cabinet and the like, water vapor in the air or condensation generated by the temperature difference between the inside and outside of the pipeline can directly contact the detection electrode, so that the resistance between the electrodes is changed, and false alarm is triggered. Frequent false alarms can not only increase the investigation workload of operation and maintenance personnel, but also lead the operation and maintenance personnel to paralyze the alarm signals, and the operation and maintenance personnel cannot respond in time when the actual leakage occurs, so that serious potential safety hazards exist. In sum, the existing leakage detection scheme cannot simultaneously consider universal suitability, construction convenience and detection reliability, is difficult to meet the leakage detection requirements of liquid cooling pipeline joints with different sizes, and cannot realize stable and reliable leakage detection in a high humidity environment. Disclosure of Invention In order to overcome the defects of the prior art, the invention provides the leakage detection module, which can simultaneously solve the core problems of poor adaptability, complicated construction and easy false alarm of a high-humidity environment of the traditional leakage detection scheme, can generally adapt to liquid cooling pipelines with different outer diameter sizes without customizing the design according to the pipeline size, greatly simplify the installation construction steps, improve the installation efficiency, effectively prevent the false alarm caused by environmental water vapor and pipeline condensation, still maintain the reliable leakage detection performance under the high-humidity environment, and satisfy the actual use requirements of a liquid cooling sys
