With the continuous growth in demand for AI computing power, the heating power of a single AI data center cabinet has surpassed 20kW or even higher. Traditional temperature monitoring solutions face heat dissipation bottlenecks and energy efficiency challenges in high power density scenarios. To solve this technical challenge, AI liquid-cooled server equipped with EXSENSE excellent-reliability NTC temperature sensor has emerged. It uses liquid as the refrigerant to remove the heat generated by the equipment, offering higher heat dissipation efficiency compared to traditional air cooling.

Maintaining dynamic matching between coolant supply temperature and flow rate in AI liquid-cooled server requires real-time and accurate temperature feedback. Without high-resolution temperature monitoring nodes, instantaneous thermal shocks caused by sudden AI load changes are difficult to be captured and compensated for in time. Based on these design requirements, EXSENSE liquid-cooled server NTC temperature sensors have become an indispensable "thermal sensing nerve" in data center liquid-cooled system. At the core heat source layer, NTCs are installed on the GPU and CPU cold plates to monitor their junction temperature in real time, providing a direct basis for temperature control system regulation. At the cooling layer, EXSENSE temperature sensors are installed in the coolant inlet and outlet pipelines to monitor coolant temperature changes, allowing the server to more intuitively evaluate the heat dissipation effect of the liquid-cooled system. With the assistance of NTC temperature sensors, AI liquid-cooled server has shifted from "passive response" to "active regulation".

The reason why EXSENSE liquid-cooled server NTC temperature sensor is capable of handling the temperature sensing tasks of data center liquid-cooled system is because:

1. Excellent reliability: The special NTC ceramic materials and manufacturing process adopted by the EXSENSE temperature sensor endow it with stable electrical performance. During long-term operation, its resistance value and beta drift rates are low, ensuring consistency in AI liquid-cooled server temperature monitoring data and preventing system misjudgments caused by NTC failures.

2. Fast response: The temperature-sensing head of NTC temperature sensor is placed in a thin stainless steel housing (304L, 316L), giving it a smaller thermal time constant compared to traditional NTCs. This allows for faster response to junction temperature changes in AI liquid-cooled server. When there is a slight fluctuation in temperature, temperature signals can be promptly transmitted to the control system to maintain smooth server operation.

3. Customization: The design and application scenarios of AI liquid-cooled server varies, so EXSENSE Electronics offers customized services to meet the needs of various design solutions. By customizing NTCs, the thermal management capabilities of liquid-cooled systems can be further strengthened, providing more precise temperature monitoring support for efficient data center operations.

Although the EXSENSE liquid-cooled server NTC temperature sensor is a small component in a liquid-cooled system, it carries the core function of thermal management for liquid-cooled server. From the source of temperature information collection to the basis for control decisions, and to the foundation for fault early warning, EXSENSE temperature sensor plays a fundamental supporting role at every stage. As AI computing density continues to increase and liquid-cooled technology evolves toward higher energy efficiency, EXSENSE liquid-cooled server NTC temperature sensor will continue to perform temperature monitoring tasks in the intelligent thermal management system of data center, providing better guarantee for the safe and reliable operation of AI computing power infrastructure.
