深层埋管换热技术研究热点与发展趋势分析OA

In order to dynamically analyze the research hotspots and frontier development trends in the field of deep buried pipe heat transfer,the relevant academic literature in CNKI and WOS databases in the last 23 years was tak-en as the data source,the visual knowledge map analysis software was applied to make bibliometrics and content analysis from the number of published articles,the international core institutions,and keywords to analyze the re-search hotspots and advanced analyses of the field.The results show thatthe amount of literature issued in the field of deep buried pipe research has gradually increased since 2000.The cooperation between core authors and institutions is only single-line or intra-team with fewer inter-institutional;The research hotspots and trends are characterized by stages,with different research focuses at different stages.With a series of strategic decisions such as"geothermal energy+","dual carbon target"and"14th Five-Year Renewable Energy Development Plan"and the concept of ef-ficient utilization of clean energy,the research hotspot in the field is more focused on the penetration of cross-disci-plines and innovation of technical methods.The development trend of the technology is characterized by break-throughs in mining technology,innovation and exploration of heat exchanger types and materials,optimization of research methods and expansion of medium and deep geothermal,comprehensive benefit evaluation and other new research directions in China.While the international community focuses on the performance of heat transfer,heat pump system,deep buried pipe heat exchanger and numerical simulation.The relevant data can provide reference for the research work of scholars related to deep-buried pipe heat transfer technology.
