中深层地热用地埋管换热器研究利用进展

Research Progress of Buried Pipe Heat Exchanger in Middle and Deep Geothermal Land

提取地热能使用的主要装置是地埋管换热器,本文介绍了地埋管系统的工作机理,综述了目前国内外地埋管换热器特别是中深层地埋管换热器的理论研究现状与实际利用情况,并指出了研究要点和未来发展方向。

The main device used to extract geothermal energy is the buried tube heat exchanger.This paper introduces the working mechanism of the buried tube heat exchangers,summarizes the theoretical research status and practical application of the buried tube heat exchangers at home and abroad,especially the medium and deep buried tube heat exchangers,and points out the key points and the future development direction.
