Long-Term Stable Temperature Measurement, Application of NTC Temperature Sensor in AI Liquid-cooled Server

With the exponential growth in demand for artificial intelligence computing power, the power consumption of data center continues to rise. Traditional air cooling has neared its physical limits, AI liquid cooling technology is becoming an inevitable choice for data center. Temperature control in liquid cooling system generally relies on data from temperature sensing module. Consequently, EXSENSE data center NTC temperature sensor has evolved from optional component to become core temperature-sensing element in the temperature control architecture of AI liquid-cooled server.

The installation locations of EXSENSE data center NTC temperature sensors in AI liquid-cooled server must take into account both comprehensiveness and targeting to achieve precise temperature monitoring. NTCs are installed in the coolant inlet and outlet pipes to monitor the inlet and return temperatures of the coolant. By comparing the temperature difference between the inlet and outlet coolant, the actual heat dissipation capacity of the liquid cooling system can be assessed. At the cold plates corresponding to the CPU and GPU, NTC temperature sensors are typically installed in surface-contact configurations to obtain accurate temperature data. Real-time monitoring of junction temperature effectively prevents performance frequency reduction or operational failure caused by overheating. EXSENSE temperature sensors are also installed on other heat-generating components within AI liquid-cooled server, such as power supply modules and caches, to comprehensively cover areas where temperature anomalies may occur.

During actual operation, the temperature data collected by the EXSENSE liquid-cooled server NTC temperature sensors is processed by a data acquisition module and transmitted to the control system. Based on multidimensional temperature data, the system dynamically adjusts the coolant flow rate and implements corresponding cooling strategies, shifting the temperature control mode from “passive response” to “active regulation.” This relies on the EXSENSE liquid-cooled server NTC temperature sensors:

1. Excellent Reliability: AI liquid-cooled server requires uninterrupted operation, placing stringent demands on the long-term stability of NTC. EXSENSE temperature sensors utilize advanced packaging processes, offering excellent long-term reliability. Their low resistance drift rate over time ensures stable performance parameters even in high-temperature, high-humidity liquid-cooling environments.

2. Customization: The customized services provided by EXSENSE Electronics fully meet the diverse needs of AI liquid-cooled server in data center. Through customization, NTC temperature sensors with appropriate resistance parameters and form factors can be designed based on the internal layout of the server and the distribution of heat-generating components, thereby achieving optimal temperature monitoring results.

Thanks to their fast-response and high-accuracy measurement capabilities, EXSENSE liquid-cooled server NTC temperature sensors have become indispensable component of data center temperature control system. With the assistance of EXSENSE liquid-cooled server NTC temperature sensors, the risk of server hardware damage due to uncontrolled temperatures is effectively reduced.
