PURPOSE:To maintain the temperature in the upper part of a filler part constant at the time of heat dissipation, and to keep the temperature in a cold heating medium constant, by providing a heat pipe between the center part and the upper part of a filler part of heat accumulating material, consisting of a latent heat accumulating material and a heat transfer medium. CONSTITUTION:A heat pipe 9 is provided between the center part and the upper part of a filler part of heat accumulating material, consisting of a heat accumulating material 3 and a heat transfer medium 4. In such a structure, when cold heating medium is fed into a heat exchanger 6, the filler part of heat accumulating material is stirred up by the evaporation-condensation cycle of a heat transfer medium 4, and the heat accumulated in the filler part is absorbed by the cold heating medium in the heat exchanger 6. At that time, the temperature in the upper part of a filler part is apt to be lowered, but the heat is replenished from the center part by the intermediary of a heat pipe 9, so that the temperature in the upper part will not be lowered. Accordingly, the temperature in the heating medium in a heat exchanger 6 can be kept constant at a high temperature all the time. |
