英文摘要	A new anti-freezing solar flat plate collector was designed, which added the energy storage layer of phase change between heat absorbing plate and thermal insulation layer. Phase change material had large latent heat, and phase transition temperature was 277.15-281.15 K. The formula to compute the designing thickness was derived based on its heat transfer mechanism. Three-dimensional unsteady numerical model of this collector was built by ANSYS Fluent. Using this model, outlet temperature and the lowest temperature of water in this collector were simulated under different working conditions. The results show that this new collector can effectively prevent the water in collector from freezing. The lowest temperature of water in this collector is higher than 275.15 K on the day of the lowest ambient temperature in winter. Compared with normal solar flat plate collector with the same construct parameters, the net heat gain of this new collector is 1.3 MJ/m2 higher on the typical cloudy day, and 0.7 MJ/m2 higher on the typical sunny day in winter. © 2016, Central South University Press.
