As the core hub for information storage and processing, data center handles massive amounts of computational tasks. The heat generation power of a single cabinet has already exceeded 20kW or even higher levels. AI liquid-cooled server, with its efficient cooling methods, have become key equipment for ensuring stable operation of data center. EXSENSE excellent-reliability NTC temperature sensors provide real-time and accurate temperature feedback in AI liquid-cooled server, enhancing its stability, and helping data center work safely and optimize energy efficiency under high-power density environments.

Installing AI liquid-cooled server EXSENSE NTC temperature sensor requires coverage of two key nodes: the heat source and the cooling system, to form a complete temperature monitoring network:

1. Core heat source layer: NTCs are placed on GPU and CPU cold plates in a surface mount package, directly sensing local cold plate temperatures, providing first-hand signals for junction temperature trends and throttling protection. Some high-density solutions adopt a multi-point layout of NTC temperature sensors on the cold plate surface to reduce the probability of false readings caused by local temperature measurement blind spots.

2. Cooling liquid loop layer: EXSENSE temperature sensors, using insert-able or ferrule packaging, are placed in the cold plate inlet and return pipes. By measuring the temperature difference between the inlet and outlet coolant, they evaluate the actual heat exchange efficiency between the cold plate and the CDU.

3. CDU and heat exchanger layer: NTCs are placed at the secondary-side supply and return liquid nodes to monitor the approaching temperature and heat exchange deterioration trends in the central cooling distribution stage.

The multi-point deployment of EXSENSE AI liquid-cooled NTC temperature sensors allows the controller to use cross-verification of cold plate temperature, coolant inlet/outlet temperature difference, and CDU supply/return liquid temperatures to distinguish between “chip load increase” and “coolant-side cooling capacity decline”, and accordingly adjust chip-level power or system-level flow/cooling. They are indispensable components in the liquid cooling thermal management chain. In actual deployment, what advantages help EXSENSE AI liquid-cooled server NTC temperature sensors ensure long-term reliable operation in server?

1. Excellent reliability: EXSENSE temperature sensors are packaged through a special process to keep aging rates low during continuous use, reducing false thermal control or protection errors caused by measurement drift, and lowering the probability of unplanned server downtime.

2. Customization: EXSENSE Electronics can provide different parameters and packaging forms based on the heterogeneous internal space of AI liquid-cooled server. This transformation from “measuring” to “measuring accurately and adaptable” is the physical foundation for long-term effective monitoring of NTCs in AI liquid-cooled server.

With the continuous increase in AI computing power consumption, liquid cooling has become mainstream. The thermal perception capability directly determines the reliability, energy efficiency and hardware lifespan of the liquid-cooled system. EXSENSE AI liquid-cooled server NTC temperature sensor, as a distributed temperature measurement carrier, plays an important role in the entire thermal management system. EXSENSE AI liquid-cooled server NTC temperature sensor is a necessary condition for the liquid-cooled system to evolve from "having heat dissipation capacity" to "having controllable heat dissipation capacity", and it is also a fundamental temperature perception facility for AI data center to maintain computing continuity and hardware lifespan under high power density.
