For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] like Figures 1 to 3 As shown, the embedded ceramic heat storage structure for distributed heating in this embodiment includes an outer tube body 1, the tube body 1 is used to protect the ceramic inner tube 3 to prevent accidental damage to the ceramic inner tube 3, and an installation cavity 2 is arranged inside the outer tube body 1, and the installation cavity 2 is used to install the ceramic inner tube 3. The ceramic inner tube 3 is installed inside the installation cavity 2. The ceramic inner tube 3 has fast heat conduction and slow heat dissipation, and its own specific heat capacity is low. Under the condition of constant temperature, the ceramic inner tube 3 made of ceramic absorbs and releases less heat than the metal tube. The ceramic inner tube 3 is installed on the outside of the tube body 1 through the installation cavity 2. A plurality of honeycomb holes 4 are arranged on the front end surface of the porcelain inner tube 3. By setting the honeycomb holes 4, the heat inside the honeycomb holes 4 can be quickly transmitted from the inner wall of the honeycomb holes 4, thereby realizing rapid heat conduction and good heat conduction effect. The plurality of honeycomb holes 4 are arranged in a honeycomb shape, and heat conducting rods 5 are installed inside the honeycomb holes 4. The heat conducting rods 5 have certain thermal conductivity and can transfer heat from one end to the other end, and the heat conducting rods 5 have unidirectional conductivity to heat. A flow channel 6 is formed between the heat conducting rods 5 and the honeycomb holes 4, and the flow channel 6 is used for the flow of heat exchange fluid to realize the heat exchange function of the heat exchange fluid.

[0020] Specifically, the shape of the ceramic inner tube 3 can be circular, square or conical, the size of the installation cavity 2 matches the shape of the ceramic inner tube 3, the shape of the ceramic inner tube 3 is not limited, and can be designed according to actual use. The ceramic inner tube 3 is installed inside the outer tube body 1 through the installation cavity 2. Regardless of the shape of the ceramic inner tube 3, it is provided with a honeycomb hole 4.

[0021] Furthermore, heat exchange fluid flows in the flow channel 6 , and the heat exchange fluid enters the flow channel 6 and contacts the heat conducting rod 5 and the ceramic inner tube 3 inside the flow channel 6 , thereby realizing the heat exchange function of the heat exchange fluid.

[0022] Furthermore, the thermally conductive rod 5 is an alloy thermally conductive rod, and the thermally conductive rod 5 is made of any one of lead, copper and steel. The thermally conductive rod 5 has good thermal conductivity, and the thermally conductive rod 5 made of lead, copper and steel has lower economic cost than the thermally conductive rod 5 made of other materials.

[0023] Furthermore, connecting plates 7 are installed at both ends of the outer tube body 1, and a plurality of connecting holes 8 are arranged through the connecting plates 7. By using the connecting holes 8 on the bolted connecting plates 7, it is convenient to install the outer tube body 1 and to use it together with other equipment.

[0024] The method of using this embodiment is as follows: when in use, the outer body 1 is installed on an external device. When an external heat source provides thermal energy to the ceramic inner tube 3 inside the outer tube body 1, the ceramic inner tube 3 absorbs the heat and conducts the heat. When the external heat energy stops supplying heat, the heat inside the ceramic inner tube 3 begins to be transmitted to the outside. Since the heat temperature inside the ceramic inner tube 3 is higher than the external temperature, the heat energy is transferred from the high temperature area to the low temperature area in the form of heat transfer. The heat transfer process of the ceramic inner tube 3 will release the heat. This heat release can be carried out for a long time, thereby providing a long-lasting heat source and realizing long-lasting heating.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
