PURPOSE:To provide a tank capable of taking a heat storage capacity to the maximum and of securing the flow speed of a heat transfer medium having the temperature efficiency of heat exchange by determining the diameter of the heat storage tank and the ratio of the full length to a specific renge and closely accommodating small spherical heat storage bodies 12 filled with heat storage mediums in the heat storage tank. CONSTITUTION:When the diameter of a heat storage tank 1 is represented by D and a length between one drum lid 3 and other drum lid 4 by L, the ratio between D:L is set in a range of 1:3-6. The reason why the length L is selected within the range of 3-6 with respect to the diamet D which is set at 1 is because a large or small pressure loss is caused as a result of a fluid friction depending upon the number of small spherical heat storage bodies. The heat transfer medium enters into one partitioned chamber 10 through one connecting port 5 by the pressure of a pump, and is widely diffused along the wall surface of the partitioned room 10, and then flows equally into respective parts having a section perpendicularly intersecting the flow direction toward the inside 11 of the tank through respective flow ports 9 of flow diffused members 7. Then, the heat transfer medium passes through cavities of the group of small spherical heat storage bodies 12 densely accommodated in the tank, and is heat-exchanged with these heat storage bodies 12, thus reaching other parts and flowing out of respective flow ports 9 of the diffusion members 8 and leaving the tank. |
