PURPOSE:To prevent an accident, to increase the accumulating efficiency of heat, and to decrease energy loss in the title heat exchanging element, by piercing a heating medium pipe through a cylindrical casing, by movably providing a sliding cup in the casing, by providing fins to the outer surface of a heating medium pipe in the casing and to the inside wall of a casing, by providing fins to the outer surface of a casing as well, and by charging the casing with a heat accumulating material. CONSTITUTION:A heating medium pipe 1 is longitudinally pierced through a cylindrical casing 2, and a heat accumulating material 3 is changed into the casing 2. A plurality of fins 4 are provided to the outer surface of a casing 2, and movable sliding cups 5 and coil springs 6 and 7 to energize the sliding cups from the back to the inside are provided at one end, and the inside of a casing. A plurality of disk fins 10 are provided to the outer surface of a heating medium pipe in the casing, and a plurality of fins with flange 11 are provided to the inside wall of a casing. Heat transferring operation from the heating medium pipe to the heat accumulating material and that from the heat accumulating material to the casing are taken place highly efficiently by the intermediary of a plurality of fins, respectively. When the heat accumulating material is expanded or contracted, the sliding cup is moved in accompany with the state of heat accumulating material to allow the change in volume of the heat accumulating material. |
