Embodiment 1
[0039] Embodiment 1: as Figure 1-Figure 3As shown in this embodiment, a single-tank stacked bed heat storage device with a bionic vein structure arranged in accordance with the generalized Murray's law is composed of a stacked bed heat storage tank, a heat storage bulb, and an inlet and outlet pipe section: The stacked bed heat storage tank includes a cylindrical main storage tank 1, a frustum-shaped auxiliary storage tank 2 at the upper end, and a truncated-shaped auxiliary storage tank 3 at the lower end. The auxiliary storage tank 2 is connected to the main storage tank 1 through a flange 6, and the auxiliary storage tank 3 is The flange 7 is connected to the main storage tank 1, the upper auxiliary storage tank 2 is connected to the heat transfer fluid inlet 4, and the upper auxiliary storage tank 3 is connected to the heat transfer fluid inlet 5; the cylindrical heat storage tank 1 is connected at the top and bottom respectively Add deflectors 8 and 9, and between the tw...
Embodiment 2
[0044] Embodiment 2: as Figure 4-Figure 6 As shown, this embodiment describes a single-tank stacked bed heat storage device with a bionic vein structure arranged in accordance with the generalized Murray's law. The difference between this embodiment and Example 1 is that the bionic vein structure is different. This embodiment is a rhombus bionic vein structure.
Embodiment 3
[0045] Embodiment 3: as Figure 7-Figure 9 As shown in this embodiment, a single-tank stacked bed heat storage device with a bionic vein structure arranged according to the generalized Murray's law, the difference between this embodiment and Example 1 or 2 is that the bionic vein structure is different, this embodiment It is an umbrella-shaped bionic vein structure.
[0046] In Example 1-3, a single-tank stacked bed heat storage device with a bionic vein structure arranged according to the generalized Murray's law, by changing the arrangement and size of the phase-change heat storage balls in the storage tank, the heat storage system Compared with traditional systems, it achieves higher heat storage efficiency, greater heat storage density and faster thermal response capability. The bionic vein structure adopted in this layout structure is a naturally selected efficient nutrient transport system, which has unique advantages in material transport and energy transfer.
