Air-Cooling and Liquid-Cooling Solutions for AI Server Thermal Management
Air-Cooling and Liquid-Cooling Solutions for AI Server Thermal Management
As the power consumption of AI servers and high-performance computing equipment continues to increase, thermal density keeps rising, making the cooling system a critical factor affecting system stability and long-term operational reliability. In practical applications, relying on a single parameter is often insufficient to evaluate cooling performance. Engineers usually need to monitor temperature, airflow, and cooling-medium conditions simultaneously to gain a more comprehensive understanding of system operation. For the commonly used air-cooling and liquid-cooling architectures of AI servers, eyc-tech provides a range of measurement products that can be flexibly selected according to actual requirements, helping users establish stable and long-term thermal monitoring configurations.
TP05 is a temperature transmitter designed by eyc-tech for industrial and equipment applications. It can be applied to temperature measurement in either air or liquid media and is suitable for deployment as a temperature monitoring point in AI server air-cooling or liquid-cooling systems, serving as one of the fundamental data sources for assessing cooling conditions.
Product Features：
● Suitable for air and liquid media
Can be installed around equipment, within airflow paths, or in coolant pipelines according to application requirements.● Supports digital and analog outputs
Allows flexible integration into existing monitoring or control systems as a temperature data source.● Measurement range configurable via RS-485
Enables adjustment of the measurement range based on different application conditions, improving flexibility and reducing reconfiguration effort.● Compatible with the eyc-tech SD05 display module
Can be paired with the eyc-tech SD05 SD05 Integrated Signal Indicator for on-site temperature display, making it suitable for installation on racks or at equipment locations and allowing convenient real-time monitoring of temperature status.Rack-Based Air-Cooling Architecture — Monitoring Rack Airflow via Temperature, Humidity, and Differential Pressure
In AI server rack air-cooling architectures, cooling performance depends on temperature distribution, environmental conditions, and whether airflow can pass smoothly through the equipment heat-dissipation zones.
Because airflow patterns inside racks are often complex, differential pressure is commonly used in practice as an indicator of airflow presence and flow resistance changes. When combined with temperature and humidity monitoring, it provides clearer insight into rack cooling performance.
Recommended Measurement Configuration：
TP05 Temperature Transmitter
Measures temperature changes around equipment or at air inlet and outlet locations to track thermal load conditions.
THS17-MD Temperature and Humidity Transmitter
Deployed inside the rack or at the front and rear sides to monitor environmental temperature and humidity as references for operating conditions and condensation risk.
PHD330 Differential Pressure Transmitter
Measures pressure differences between different locations within the rack to assess airflow presence, resistance changes, and air-supply conditions.
