Embodiment 1

[0039] Example 1: Such as Figure 1 - Figure 3As shown, the present embodiment is a single-cans of the bionessing condensation bed in accordance with generalized Murram, which consists of a stacked bed housing, heat storage ball, and an inlet pipe section: The accumulation bed storage can include cylindrical main storage tanks 1, upper round serial container 2 and lower round serial container 3, the sub-storage tank 2 is connected to the main storage tank 1, the secondary storage tank 3 passes The flange 7 is connected to the main storage tank 1, and the upper secondary storage tank 2 is connected to the heat transfer fluid inlet 4, and the upper side storage tank 3 is connected to the heat transfer fluid inlet 5; the cylindrical heat can 1 at the top and bottom respectively When the flow of the flow plates 8, 9, the binding bed composed of the two guiding plates, and the gap is used as the heat transfer medium flow channel; the pile of heat is arranged in the form of a bionic cont...

Embodiment 2

[0044] Example 2: Such as Figure 4 - Figure 6 As shown, the present embodiment is a single-canable bed heat storage device having a bionic contestant arrangement in accordance with Generalized Murra, the present embodiment is different from that of Example 1 in that the bionic clipph is different, and the present embodiment is diamond. Bionic context structure.

Embodiment 3

[0045] Example 3: Such as Figure 7 - Figure 9 As shown, the present embodiment has a single-canage bed heat storage device having a bionic context in accordance with Generalized Murra, the present embodiment and the embodiment 1 or 2 differ in that the bionic clipph structure is different, and the present embodiment It is an umbrella bionic context structure.

[0046] In Examples 1-3, a single-tank stacked bed heat storage device having a bionic climb structure in accordance with generalized Murram is arranged, and the heat storage system is made by changing the arrangement and size of the phase change hotspot in the tank. Higher heat storage efficiency, greater heat storage density, and faster thermal response capacity are achieved compared to traditional systems. The bionic clipphic structure employed by this arrangement is a naturally selected high-efficiency nutrient transport system that has unique advantages in material transport and energy transfer.

Abstract

The invention relates to a single-tank stacked-bed heat storage device arranged according to generalized Murray's law and having a bionic vein structure and a method for using the same, belonging to the field of energy storage. It solves the problems of low heat storage density, small heat exchange area and uneven heat storage speed in the traditional stacked bed heat storage system. Key points: The heat storage device includes a storage tank, and a bracket is set in the storage tank in the form of a bionic venation structure. The heat storage bulbs with different diameters are arranged in the storage tank according to the generalized Murray's law. The bracket is used to support the heat storage bulb and prevent it. Feel free to float. The method of use realizes heat storage, heat release and heat storage by following the generalized Murray's law to arrange heat storage balls with a bionic vein structure. Compared with the traditional system, the heat storage system achieves higher heat storage efficiency, greater heat storage density and faster thermal response capability by changing the arrangement and size of the heat storage balls in the storage tank. Structure is an efficient nutrient transport system selected by nature, which has unique advantages in material transport and energy transfer.

Description

Technical field [0001] The present invention relates to a single-canage bed heat storage device, and specifically, a single-canage bed heat storage device having a bionic contest in accordance with the generalized Murram, which is a method of use, belonging to the field of energy storage. Background technique [0002] At present, the study of solar energy is gradually increased, but since the periodicity of solar radiation makes it necessary to temporarily store the obtained energy. At present, it is mainly stored by a hot storage tank, a relatively common heat storage method is divided into a dual-canned heat storage system and a single-canage heat storage system. Among them, commercial medium storage tanks often use a dual-canned heat storage system, which consists of hot and cold, but the system cost is large. The single-canned heat storage system is also known as the heterogeneous temperature layer, and the heat storage process is carried out by a tank, and the advantage is t...
