Abstract：A heat storage system with parabolic trough vacuum tube collector and thin-wall phase change and heat storage box was built in this paper. This system used paraffin as the phase change material,then used the hot water produced by a parabolic trough vacuum tube heat collector to store heat for the thin-wall phase change and heat storage box with the size of 800 mm×60 mm×800 mm. The heat release process and the phenomenon of thermal stratification were studied and tested. Measuring points of temperature and heat flux were arranged in the thin-wall phase change and heat storage box,then according to the test and analysis of wall temperature,the internal temperature and wall heat flux,conclusion of the thermal stratification phenomenon was made and application suggestions were also put forward.
