🎓🤝-86°C Deep-Freeze Cold Chain Storage Equipment

The product primarily incorporates proprietary technology for mobile cold chain containers based on high-power Stirling refrigeration technology. Through ingenious design and arrangement of the expeller structure and power piston structure, the compression chamber volume is increased, significantly reducing expeller motion damping during high-power refrigeration operation. Multiple synchronously operating power piston structures and a single expeller piston structure are employed to further expand the compression chamber volume. This achieves a broad cooling temperature range and high refrigeration capacity, delivering 1.0–1.5 KW of cooling power within the -196°C to -80°C range. Additionally, the cold chain container employs fixtures and heat pipes to enable direct heat transfer between the refrigeration unit's cold head and the aluminum inner liner, resulting in a simpler structure and superior heat transfer efficiency.

🎓🤝Pressureless New Pipeline Self-Propelled Internal Inspection System

To achieve stable operation of low-pressure, low-flow pipeline detectors, this study builds upon previous electric self-climbing internal inspection tools. By integrating the working principle of fluid-driven detectors—specifically their pressure drop during flow—we propose a novel detection method for a hybrid pneumatic-electric drive detector. The low-flow/low-pressure design reduces the resistance of the pipeline inspection tool.

The project has now achieved engineering application, with the inspection performance of the self-propelled internal inspection equipment fully validated. Through multiple rounds of field testing, the equipment demonstrates stable operation across diverse pipeline environments, meeting anticipated technical specifications for inspection accuracy. Its development and deployment significantly enhance inspection efficiency for newly constructed pipelines, effectively ensuring pipeline integrity. No comparable products exist domestically or internationally.
