In this paper, analytical solution to realistic transit heat conduction problem for slab-type heat-exchanger in energy subways station is studied. Firstly, it is discussed weather an underground structure in energy subway station could be used as heat-exchanger for a qualified heat exchanger should have enough surface area to contact the heat source which meets the temperature requirement. Qualified heat-exchangers in energy subway station are classified as slab-type heat-exchangers and column-type heat-exchangers according to their shape. Secondly, theoretical solution to realistic transit heat conduction problem for slab-type heat-exchanger in energy subways station is presented after an analysis of the realistic heat conduction problem and transforming the rectangle-wave heat flux boundary condition to trigonometric function polynomial using Fourier Transformation. Finally, the theoretical solution is validated using numerical solution by build numerical modals.
