Directed at the key problem about the heat transfer between heat pipes and piles found in the ground source heat pump system (GSHP), a new finite element method is adopted in this paper to provide a finite element scheme for piles and U-bent tubes.And then a calculation on the term of heat transfer between the pile and the U-bent tube through the point integration method is made.Then the value of the convective heat transfer coefficient h will be determined through the definition of the Nussellt number. Finally three illustrative examples are given in this paper to verify the rationality of our format. The model proposed in this paper has broken through the restrictions of the traditional analytical solutions, making it able to be applied widely in various projects.
