PURPOSE:To prevent the temperature decrease of the upper part of a heat accumulating material packing part upon discharging heat by transferring heat in the central part of the heat accumulating material packing part through a heat pipe and keep the temperature thereof constant by a method wherein the central part of the heat accumulating material packing part and a heat exchanger in the part of space are connected by the heat pipe. CONSTITUTION:When low-temperature heat medium flows into the heat exchanger in case the heat accumulating device 1 is in a heat accumulating condition, the heat accumulating material packing part is mixed by the evaporation-condensation cycle of the heat transfer medium 4 while the heat transfer medium effects heat exchange in the heat exchanger 6 and dissipates the heat thereof. At this time, the temperature of the upper part of the heat accumulating material packing part is reduced, but the temperature decrease is prevented by arranging the heat pipe 9 from the central part to the upper part of the same packing part. In case the temperature decrease of the upper part is prevented, the same in the part of space is also prevented and a constant heat exchange is effected by the heat exchanger 6. The heat dissipating part of the heat pipe 9 is contacting with the heat exchanger 6 at a place 11, therefore, the heat, having comparatively high temperature, in the central part of the heat accumulating material is transferred by the heat pipe 9 and the heat exchange is effected effectively in the heat exchanger 6. |
