Abstract

The study on thermal deformation of heat exchange pipe fixed in borehole was implemented. The thermal deformation of pipe buried in backfill was measured, and three typical shapes of pipe in non-backfilled borehole were selected to research thermal deformation behavior when they were suffering in heating process. It indicated that the pipes in different initial shapes showed different deformation behavior. Further analysis of the results indicated that frequent thermal deformation of pipe could result in impacts on the structure of ground heat exchange system, which will be the important factor for the performance degradation and reliability reduction.
