Latent heat accumulator for use as e.g. overheating protection device in open solar receiver system of solar power station, has cells are made of high temperature-steady material and limit at channel, where fluid flows through channel

摘要

The accumulator has fine-cellular cells (13) provided with phase change material (PCM) (14) that is enclosed by ceramics or graphite, where each cell stays in heat exchange with heat transfer fluid. The phase change material is formed as metal or salt, where fusion temperature of the phase change material is greater 800 degree Celsius. The cells are made of high temperature-steady material and limit at a channel, where the heat transfer fluid flows through the channel. The cells are formed as parallel channels (11, 12) in a body, where width of the cells is maximally 2 cm.
