PURPOSE:To provide a heat accumulator which can effectively retrive the heat from a heat source remarkably varying and separately move heats from respective heat accumulation tanks in response to utility by forming a plurality of heat accumulating units of different heat capacities in a heat accumulating tank. CONSTITUTION:A heat accumulating tank 2 has a plurality of chambers 4-7 in a heat insulating material 3, in which heat accumulating materials A1-A4 having larger heat capacities sequentially from the left end chamber 4 toward the right side materials per unit volume are filled to thus form one high temperature heat accumulating unit H and three high temperature heat accumulating units L1-L3, which are connected through respective heat pipes 8 to a conduit 1. Since four heat accumulating units H, L1-L3 are provided in the tank 2, the unit H can be retained at high heat accumulating temperature T2, and the units L1-L3 can be retained at low heat accumulating temperature T1 to thereby effectively retrieve the heat energy from the heat source varying remarkably. |
