A novel energy pile: The thermo-syphon helical pile [PDF]
Applied Thermal Engineering, 2019 Abstract This study focuses on assessing the heat transfer rate and structural stability of a novel self-operating energy pile based on the principle of a thermo-syphon. Specifically, this new energy pile, referred to as a “thermo-syphon helical pile” (THP), is formed by pressurizing a hollow helical pile with carbon dioxide (CO2) to form a heat pipe,
