PURPOSE:To accelerate transfer of heat of a fluid heat-accumulating substance sealed in capsules, by rotating and vibrating the capsules, in a capsule-type heat accumulator. CONSTITUTION:In each of capsules 2, round rods 4 of shape-stabilized polyethylene having a diameter of 2-5mm. are sealed as a fluid heat-accumulating substance together with a fluid 5 hardly compatible with polyethylene such as a silicone oil or water containing an anti-deterioration agent. When a hot heat- transmitting medium is introduced through an inflow port 1a of a tank 1 and is passed through the gaps between the capsules 2, it exchanges heat with the capsules 2, and when the temperature of the fluid 5 is raised to 135 deg.C, the round rods 4 are completely melted, and heat of melting is accumulated as latent heat in the capsules 2. In this heat accumulator, each of the capsules 2 is rotated in the interior of the tank 1 by a shaft 3, so that transfer of heat in the capsules 2 is accelerated, and heat-accumulating speed is increased. |
