Description

technical field [0001] The invention relates to a high-precision liquid leakage detection and recovery early warning device. Background technique [0002] With the advent of the 5G communication era, the use of high-power integrated circuit modules is more popular, the power density is high, the heat loss increases, and the temperature of the device rises when it is used. Therefore, higher cooling requirements are put forward for module-level equipment. In order to adapt to the cooling design trend of miniaturized high-power integrated circuit modules, liquid cooling technology will be more widely applied to electronic chassis and cabinet-level heat dissipation fields equipped with multiple high-power circuit modules. In the practical process of liquid cooling technology, due to the comprehensive influence of various factors such as processing, technology, operation, harsh environment, design defects of liquid cooling structure, and aging of sealing rings, coolant leakage of...

AI Technical Summary

Problems solved by technology

Leakage of coolant reduces the cooling effect of a single module, affects the electrical performance of the module, and at the same time causes pollution to the internal environment of the chassis and cabinet where the module is installed, and even damages other adjacent modules

[0003] Traditional liquid leakage detection mostly uses resistive sensors, which have the following defects: First, the probes of resistive sensors are suspended in the air. By measuring the resistance value between the probes, it is judged whether there is liquid between the probes. Misjudgments and false alarms are caused, and the suspended state of the probe is easily damaged; second, the conductivity of traditional coolant itself is low, and the resistance value is relatively large in the two states of no leakage and leakage, which is converted into a voltage signal Third, the traditional liquid leakage detection device only detects and does not recover. When the leakage is large, the coolant flows out from the leakage point, accumulates inside the cabinet where the module is installed, and cannot be discharged, which will cause serious damage. The coolant in the cabinet is soaked, so that the components in the cabinet cannot continue to be used, and the function is lost
