PURPOSE:To distribute high-temperature energy into a center tank and the low-temperature energy into the outside tank and reduce natural heat emission by a method wherein the heat accumulating tank is constituted into coaxial multi-layer tank type and the difference of specific gravities due to a temperature difference is utilized in the distributing mechanism of the heat. CONSTITUTION:Coaxial inside and outside partitioning tubes 2, 3 are provided in a casing 1 to form the center tank N and annular outer and inner tanks A, B. The lower end 4 of the inside partitioning tube 2 is located at a higher position than the lower end 5 of the outside partitioning tube 3. A supplying pipe 7, supplying hot fluid from a heat collecting device 15 is projected to the lower position of the inside partitioning tube 2 and an air gap (a) is formed at the tip end thereof by two sheets of plates 8, 9. The dynamic pressure of introduced water is restricted by an annular gap 10 between the tip end of the air gap (a) and the inside partitioning tube 2 while the ascending and descending of heated water are selected by the difference of specific gravities due to the temperature difference. Separated layers due to the difference of the specific gravities are formed in the outside annular gap 13 between the annular peripheral part 11 of the lower end of the inside partitioning tube 2 and the air gap (b) of the lower flat plate 12 and, further, are communicated with the air gap C between the lower end 5 of the outside partitioning tube 3 and a bottom surface 6. The center tank N is heated at first preferentially and, then, the inner tank B and the outer tank A are heated sequentially. |
