Comparing air vs liquid cooling for medical imaging

PET (Positron Emission Tomography) scanners require highly stable thermal management to ensure imaging accuracy and detector performance. Liquid-to-liquid cooling modules, such as Huajing’s TE-series, provide precise temperature control (±0.1°C) while minimizing vibration and noise—critical factors in medical imaging.

Why Liquid-to-Liquid Cooling for PET Scanners?

Precision Temperature Control

PET detectors (e.g., silicon photomultipliers) are sensitive to thermal fluctuations.
Huajing’s TE05-40XXEL and TP23072 modules maintain ±0.1°C stability, reducing image noise.

Compact & Vibration-Free

Unlike compressor systems, liquid cooling eliminates mechanical vibrations that degrade scan resolution.
Modular designs (e.g., TE49-200XFL) integrate seamlessly into scanner gantries.

Energy Efficiency

Direct liquid cooling reduces power consumption by 20-30% compared to air-based systems.
