A sealing strip 4 is arranged along the circumferential direction of the thermal insulation board 3. The sealing strip 4 is of a hollow structure, and the hollow part is evenly filled with adsorption blocks. The adsorption blocks are made of a ferromagnetic material or iron, and attraction is generated between the adsorption layer and the adsorption blocks.

    [0051] During heat storage, the hot water prepared by the heat source flows through the hot water valve 12 and enters the tank evenly through the first water distributor 6. At the same time, the cold water at the bottom of the tank flows out from the second water distributor 7 through the cold water valve 14 and enters the hot fluid source. The thermal insulation board in the tank is at the junction of the hot and cold water, and a thermocline moves down synchronously.

    [0052] During cold storage, the cold water prepared by a refrigerator flows through the cold water valve 14 and evenly enters the tank through the second water distributor. At the same time, the hot water in the upper part of the tank flows out through the first water distributor 6 and enters the refrigerator. The thermal insulation board in the tank is at the junction of the hot and cold water, and the thermocline moves up synchronously.

    Example 1

    [0053] The thermal insulation board is a polycarbonate endurance board, which is a circular and two-layer hollow board, as shown in (2) of FIG. 2. The frame is 1.5 mm thick, and the thermal insulation board is 15 mm thick. A -shaped silicone foam sealing strip is used at the edge, as shown in (2) of FIG. 3. The sealing strip is pasted to the thermal insulation board body by using hot melt adhesive. The 550 mm (diameterlength) neodymium iron boron (NdFeB) magnet (N45M, 7.5 g/cm.sup.3) rods with a heat-resistant temperature of 100 C. are continuously filled and arranged on the sealing strip around the entire circumference of the thermal insulation board, as shown in (1) of FIG. 4. The number of the magnet rods is selected based on the density of the hot and cold water in the hot water tank, the gravity of the polycarbonate endurance board, and buoyancy, so that the friction between the sealing strip and the wall under the buoyancy, gravity, and magnetic force allows the thermal insulation board to stay at the junction of the cold and hot fluids, and move up and down with the hot and cold fluids. The magnetic force enables the sealing strip to be tightly attached to the inner wall of the tank.

    Example 2

    [0054] The thermal insulation board is a polycarbonate endurance board, which is a circular and one-layer hollow board, as shown in (1) of FIG. 2. The frame is 2 mm thick, and the thermal insulation board is 10 mm thick. A D-shaped silicone foam sealing strip is used at the edge, as shown in (1) of FIG. 3. The sealing strip is pasted to the thermal insulation board body by using hot melt adhesive. The 100 mm10 mm2 mm (lengthwidthheight) NdFeB magnet (N45, 7.5 g/cm.sup.3) rods with a heat-resistant temperature of 80 C. are filled in the hollow part of the sealing strip around the entire circumference of the thermal insulation board, as shown in (2) of FIG. 4. The number of the magnet rods is selected based on the density of the hot and cold water in the hot water tank, the gravity of the polycarbonate endurance board, and buoyancy, so that the friction between the sealing strip and the wall under the buoyancy, gravity, and magnetic force allows the thermal insulation board to stay at the junction of the cold and hot fluids, and move up and down with the hot and cold fluids. The magnetic force enables the sealing strip to be tightly attached to the inner wall of the tank.

    [0055] The thermal insulation board is a circular low-density silicone foam porous board. Its structure is shown in (3) of FIG. 2. The thermal insulation board is 10 mm thick. A D-shaped silicone foam sealing strip is used at the edge, as shown in (1) of FIG. 3. The sealing strip is pasted to the thermal insulation board body by using hot melt adhesive. The 50 mm10 mm2 mm (lengthwidthheight) NdFeB magnet (N45, 7.5 g/cm.sup.3) rods with a heat-resistant temperature of 80 C. are filled at intervals on the sealing strip around the entire circumference of the thermal insulation board, as shown in (3) of FIG. 4. The number of the magnet rods is selected based on the density of the hot and cold water in the hot water tank, the gravity of the low-density silicone foam porous board, and buoyancy, so that the friction between the sealing strip and the wall under the buoyancy, gravity, and magnetic force allows the thermal insulation board to stay at the junction of the cold and hot fluids, and move up and down with the hot and cold fluids. The magnetic force enables the sealing strip to be tightly attached to the inner wall of the tank.

    Example 4

    [0056] The thermal insulation board is a circular high-density silicone foam porous board. Its structure is shown in (4) of FIG. 2. The thermal insulation board is 15 mm thick. A -shaped silicone foam sealing strip is used at the edge, as shown in (2) of FIG. 3. The sealing strip is seamed to the thermal insulation board body. The 0550 mm (diameterlength) NdFeB magnet (SmCo5, 7.5 g/cm.sup.3) rods with a heat-resistant temperature of 250 C. are continuously filled in the hollow part of the sealing strip around thermal insulation board, as shown in (1) of FIG. 4. The number of the magnet rods is selected based on the density of the hot and cold water in the hot water tank, the gravity of the high-density silicone foam porous board, and buoyancy, so that the friction between the sealing strip and the wall under the buoyancy, gravity, magnetic force, and friction allows the thermal insulation board to stay at the junction of the cold and hot fluids, and move up and down with the hot and cold fluids. The magnetic force enables the sealing strip to be tightly attached to the inner wall of the tank.
