The Study on Measuring Method of Heat Exchange Pipe Deformation and Displacement Based on Thermal Strain
Thermal deformation of heat exchange pipe is the significant source of structural variation in ground heat exchange system,which could weaken the capability and reduce the reliability of heat transfer system after long-time operation.The experimental study of thermal deformation of heat exchange pipe should be carded out to explore its thermal behavior.The strain measuring method was applied to the study on thermal deformation and displacement,which was deduced from the measured strain in heat exchange pipe.The verifying experiment was carried out to analyse its feasibility in preliminary simulation environment.The result showed that strain measuring method is applicable and could be conducive to the deformation monitoring of heat exchange pipe in practical projects.
