PURPOSE:To improve the rate of effective utilization of a heat accumulating material and hold small the width of variation in time of the outlet temperature of a working fluid by making uniform in the longitudinal direction the state of phase change of the heat accumulating material of a heat receiving and accumulating device used for a power generation system on a space orbit. CONSTITUTION:The outer circumference of a heat transfer pipe 31 is covered by a heat accumulating material vessel 33 which has areas defined by partition walls 32 in the longitudinal direction. The split areas in the heat accumulating material vessel 33 consists in the direction of the flow of a working fluid of a low temperature chamber 34, sub-low temperature chamber 35, sub-high temperature chamber 36, and high temperature chamber 37 from the side nearer to the person facing them, and each chamber is filled with a heat accumulating material which has a different melting point. Namely the low temperature room 34 is filled with a heat accumulating material of the lowest melting point, and successively the sub-low temperature chamber 35, sub-high temperature chamber 36, and so on with heat accumulating material with stepwise higher melting point, and the high temperature chamber 37 with a heat accumulating material of the highest melting point. The numeral 38 denotes an inlet, and from there the working fluid enters the inside of the heat transfer pipe 31 and flows out from an outlet denoted by the numeral 39. For each heat accumulating material the amount of phase change increases and the states of phase change are also made uniform in the longitudinal direction. |
