Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of heat exchange devices, and particularly relates to an inner fin heat exchange structure for extracting non-interference geothermal energy. BACKGROUND

[0002] Non-interference geothermal energy (also known as closed geothermal system or closed circulation geothermal system) is a technology that utilizes the heat inside the earth, but unlike the traditional geothermal energy development method, it does not directly exploit underground water or steam, but extracts heat from the deep underground through a closed circulation system. This method aims to reduce the impact on the environment and improve energy utilization efficiency. Through a completely closed pipeline network, usually composed of pipes made of high-density polyethylene (HDPE) or other corrosion-resistant materials, the fluid (usually water or glycol solution) circulating in the pipes absorbs the heat from the underground and returns to the ground for heating or power generation. Because it does not involve the exploitation and discharge of underground water, it can significantly reduce the impact on the underground water environment and avoid the pollution problems that may occur in traditional geothermal energy development.

[0003] In order to improve the heat exchange efficiency, fins are often arranged around the pipes to increase the heat exchange area. In the long-term use, impurities in the underground water will adhere to the fins, causing the heat conduction capacity of the fins to decrease. Since the fins are located in the deep underground, it is difficult to clean the fins. Therefore, as the use time increases, the heat exchange efficiency of the heat exchange device gradually decreases, which is not conducive to the exploitation of geothermal energy. At the same time, since the fins and the heat exchange pipes are often arranged in a staggered manner, the fins are separated into multiple narrow spaces, making it difficult to clean the fins. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide an inner fin heat exchange structure for extracting non-interference geothermal energy.
