摘　　要：建立了地埋管换热器传热模型,并对模型的可靠性进行了实验验证。利用该模型,对埋设于围岩与岩土之间(即埋深为0.5m)的地埋管的换热和围护结构表面散热量进行了分析。定量分析了埋管深度、隔热层厚度、岩土种类对围护结构表面散热量的影响。Establishes a heat transfer model of ground heat exchangers, and carries out experiments to verify the reliability of the model. By the model, analyses the heat transfer of the buried pipes between surrounding rock and rock, which is 0.5 m depth, and the heat flow through envelope surfaces. Quantitatively analyses the influences of the depth of buried pipes, thickness of insulating layer and different rocks on the surface heat flow.
