AI Technical Summary

Technical Problem

Traditional buried pipe heat exchangers are prone to pipe deformation and breakage in collapsible loess areas, and have low heat exchange efficiency. Existing solutions are costly or have complex procedures, and cannot effectively solve the problem of pipe stability.

Method used

The underground pipe system is designed with a flexible connection structure, an elastic support layer, and high-strength materials. It is connected to the inlet and outlet water pipes through a flexible connection structure to increase the pipe's deformation and fracture resistance. Elastic rubber sealing rings are used at the pipe joints, and temperature sensors are used to monitor the soil temperature in real time to regulate the temperature of the circulating fluid.

Benefits of technology

It significantly improves pipeline stability and heat exchange efficiency, reduces the risk of pipeline damage, enhances system adaptability and energy utilization efficiency, extends system service life, and reduces maintenance costs.
