The thermal performance of energy piles equipped with new metal fins to improve heat transmission is examined in this research. solid transfer module COMSOL Multiphysics was used create a 2D numerical model the pile, utilizing pile at field test site Nanjing as an example. By contrasting experimental data, model’s correctness confirmed. After that, kind fin created pile. impact type on pile’s efficiency assessed, and temperature change within soil surrounding before after set by parameters pipe configuration, buried depth, concrete conductivity. results indicate that setting run for 336 h, area increases 10.8% 12.3%, region 5.3% 8.7% when tube diameter chosen be between 20 40 mm; maximize concrete, increases, drops. For h operation, may raised 12.3% are set, around can 8.7%. improved raising through increase concrete’s conductivity; however, degree improvement diminishes conductivity rises. It intended study will offer insightful information best way design efficiency.
