With the rapid development of AI technology, the thermal management of data center is facing severe adjustments. As the core of heat dissipation, the AI liquid-cooled server uses EXSENSE high-temperature NTC temperature sensors for real-time temperature monitoring to improve data center performance.

The sensitivity of NTC temperature sensors to temperature changes makes the temperature data it collects the cornerstone of temperature regulation in AI liquid cooling server. To ensure comprehensive and accurate temperature monitoring, EXSENSE temperature sensors are installed in several key locations. First, on cold plates such as CPU/GPU, NTC is usually set up by surface-contact mounting method. This installation method can quickly sense the temperature change of the cold plate, because the cold plate acts as a heat transfer medium between the coolant and the heating device, and its temperature directly reflects the heat dissipation effect. Secondly, in the coolant pipeline, the insertion type or ferrule type is often used to install the EXSENSE liquid-cooled server NTC at the inlet and outlet positions of the coolant, which can effectively evaluate the heat exchange efficiency by monitoring the temperature difference between the inlet and outlet coolant, so as to provide important information for subsequent heat dissipation regulation.

The EXSENSE liquid-cooled server NTC temperature sensor is like a keen "temperature warrior", always performing the duty of temperature monitoring in the data center. The temperature data obtained by NTC will be converted into an electrical signal and quickly transmitted to the CDU. After receiving the data from the NTC temperature sensor, CDU will compare the junction temperature according to the preset temperature threshold for intelligent regulation. For example, when the NTC temperature sensor detects an abnormal increase in coolant temperature or the surface temperature of the component close to the warning value, the CDU will accelerate the heat dissipation by increasing the coolant flow rate to enhance the heat exchange efficiency between the coolant and the heating device. At the same time, the fan speed can also be increased to enhance air circulation volume and assist in heat dissipation.

The reason why the EXSENSE liquid-cooled server NTC temperature sensor can efficiently perform temperature monitoring tasks in data centers is that:

1. Fast response speed, can capture small temperature rise changes in time, assist CDU for precise regulation, reduce the operating power of the device in time, avoid thermal runaway caused by high temperature, effectively ensure the continuity and high efficiency of data processing tasks.

2. Great consistency, able to work stably under complex working conditions in the data center, to ensure continuous and accurate collection of temperature data. Even in the face of instantaneous temperature fluctuations caused by high-load server loads, it can quickly capture subtle changes and provide feedback, promoting the optimization of thermal management in data centers.

Without the real-time temperature monitoring of the EXSENSE liquid-cooled server NTC temperature sensor, the server is likely to experience serious problems such as performance degradation, failure, and even hardware damage due to overheating, which shows its importance in ensuring the stable operation of AI liquid-cooled server. The temperature monitoring network built by the multi-point layout of the EXSENSE liquid-cooled server NTC temperature sensor provides multi-dimensional thermal state parameters for the AI algorithm, so that the AI liquid-cooled server can take heat dissipation measures according to the actual situation to optimize energy efficiency.
