Geometric structures of a spiral plate heat exchanger, such as the angle of difference between the entrance and exit, channel width and height, heat transfer area, number of turns, are studied on the basis of heat transfer characteristics. A numerical calculation algorithm for the heat transfer equations is developed, in order to estimate the temperature distribution and overall heat transfer coefficient using the flow rates and the temperatures at inlets and outlets. Analytical solutions of the equations are also shown in the case of where the capacity-rate ratio R_c is zero. The relationship between the flow configuration and the heat transfer performance is investigated experimentally. The effect of the peculiar channel structure on the mean temperature difference is analyzed by the structure factor and the binary heat transfer factor.
