Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat storage technology, specifically a solid heat storage structure. Background Technology
[0002] Solid-state thermal storage structures are devices that utilize solid materials to store and release heat, and are widely used in energy storage for renewable energy sources such as solar and wind power. They can absorb or release large amounts of heat in a short time, thus achieving efficient utilization of renewable energy. The principle of solid-state thermal storage structures is mainly to store and release heat through phase change. During a phase change, solid substances undergo a phase transition due to temperature changes, such as changing directly from a solid to a gaseous state, or from a liquid to a gaseous state. These phase change processes require heat absorption or release; therefore, the storage or release of heat can be achieved by controlling the conditions of the phase change.
[0003] With societal development, people's demand for energy is increasing, while the depletion of traditional energy sources and environmental problems have made people increasingly aware of the importance of sustainable development and environmental protection. Therefore, a solid-state thermal storage structure is needed to store heat. Existing solid-state thermal storage structures typically use refractory materials of different compositions as storage materials. However, these materials have low thermal conductivity and specific heat, resulting in a large space required for the storage system. Furthermore, during the heat storage and release processes, existing solid-state thermal storage structures exhibit a certain temperature distribution within the space, leading to a decrease in the device's heat storage capacity.

[0022] Please see Figure 1-4 As shown, a solid heat storage structure includes a cabinet 1 with a door 2 on one side for sealing the cabinet 1 and thus facilitating the insulation of the heat storage bricks 4. A shell 3 is located at the bottom of the cabinet 1 to protect the water storage tank 7. Several heat storage bricks 4 are disposed inside the cabinet 1 to store heat. Each heat storage brick 4 has a heat-conducting pipe 5 inside for heat transfer. In the heat storage brick 4, a support frame 6 is fixed to the inner wall of the shell 3. The support frame 6 can be used to support the water storage tank 7. The top of the support frame 6 is equipped with a horizontally installed water storage tank 7. The water storage tank 7 can be used to store hot water. The inner wall of the water storage tank 7 is equipped with two partitions 8. The partitions 8 can be used to block the hot water. A heat conduction mechanism 9 is provided on one side of the water storage tank 7. The heat conduction mechanism 9 can be used to introduce heat into the heat storage brick 4 through the first exhaust port 14 and the second exhaust port 15.
[0023] The heat conduction mechanism 9 includes a support plate 91 fixed to the inner wall of the housing 3. By setting the support plate 91, the fan 92 can be easily supported. The fan 92 is set on the top of the support plate 91, and the air inlet of the fan 92 is connected to one side of the water storage tank 7. By setting the fan 92, heat can be easily introduced into the first hot air duct 94 through the first connecting pipe 93. The air outlet of the fan 92 is connected to the first connecting pipe 93. By setting the first connecting pipe 93, the fan 92 can be easily connected to the first hot air duct 94. The first hot air duct 94 is fixed to the inner wall of the housing 3, and one side of the first hot air duct 94 is connected to one end of the first connecting pipe 93. By setting the first hot air duct 94, the heat of the hot water can be easily introduced into the heat storage brick 4 through the first exhaust port 14 and the second exhaust port 15.
[0024] The outer side of the water storage tank 7 is connected to a horizontally arranged inlet pipe 10 and an outlet pipe 11. The inlet pipe 10 facilitates the introduction of hot water into the water storage tank 7, and the outlet pipe 11 facilitates the discharge of cooled water. A horizontally arranged second connecting pipe 12 is connected to one side of the water storage tank 7. The second connecting pipe 12 facilitates the connection between the second hot air duct 13 and the water storage tank 7. One end of the second connecting pipe 12 is connected to the second hot air duct 13.

By using the sealing strip 18 and the limiting groove 19 together, the connection between the cabinet door 2 and the cabinet 1 can be sealed, thereby reducing heat loss.
[0026] Working principle: In use, hot water is first poured into the water storage tank 7 through the inlet pipe 10. The hot water is separated by the partition 8. Then, the heat from the hot water is introduced into the cabinet 1 through the first exhaust port 14 and the second exhaust port 15 using the support plate 91, the fan 92, the first connecting pipe 93 and the first hot air duct 94. The heat is then evenly distributed into the heat storage brick 4 through the heat conduction pipe 5. The second connecting pipe 12 and the second hot air duct 13 are used to introduce the heat from the hot water into the heat storage brick 4 from the first exhaust port 14 and the second exhaust port 15 from another direction. The heat insulation layer 16, the sealing strip 18 and the limiting groove 19 are used to insulate the cabinet 1 and seal the connection between the cabinet door 2 and the cabinet 1 to prevent heat loss from the heat storage brick 4, thereby improving the heat storage quality of the device.
