| Abstract: | A quasi-3 D model for buried spiral tube heat exchanger in pile foundation is established based on the line heat source theory and the continuous heat source method in Green function method. The model is calculated by Matlab. The influences of soil thermal conductivity, initial soil temperature, spiral tube pitch, pile radius and flow rate of fluid on the heat exchange performance of the heat exchanger are analyzed under the given conditions. |
