Description

Technical Field

[0001] The utility model relates to the field of phase change heat storage devices, in particular to a phase change heat storage device for a heating unit. Background Art

[0002] Phase change heat storage technology is a technology that achieves efficient heat storage on a low-energy heat path. It extends temperature and humidity control to a range of temperatures to maintain indoor temperature stability while obtaining stored energy. This technology is widely used in industries such as new energy power generation, cooling and heating electromechanical facilities, etc. Although the phase change heat storage device currently used can meet the thermal energy storage function, it still has defects during use;

[0003] For example, the patent provides a heat storage device for a heating unit with the authorization announcement number CN218545403U. The patent utilizes the heat energy on the heating unit to heat the cooling water medium, and then utilizes the heated cooling water medium to heat the heat conversion material; utilizes the temperature increase of the heat storage body to store heat, so that the temperature of the heat conversion material inside the heat storage body increases and vaporizes, and the electromagnetic switch is turned on to transport the vaporized heat conversion material to the outside for heat supply, and the cooled heat conversion material is transported to the inside of the heat storage body again to achieve the effect of circulating heat supply; solves the problem that the current heat storage device has a slow heat storage / release rate and efficiency during the heat storage process, and cannot quickly and flexibly convert the storage / release heat, resulting in a slow conversion efficiency of the heat storage device and affecting the heat storage effect of the heat storage device. In addition, during the heat storage stage of the heat storage device, the heat medium is transported to the heat storage device and heats the heat storage medium in the heat storage device, and the heat storage medium cannot circulate to store heat for heating, resulting in a waste of resources;

[0004] However, the heat storage device is not convenient for cleaning the inside of the insulation cover. Since hot air is stored in the insulation cover for a long time, the hot air passes through the insulation cover for a long time, which easily causes scale to form inside the insulation cover. If it is not cleaned, the scale will accumulate more and more, which will affect the insulation effect of the insulation cover. At the same time, the falling of scale will also cause the hot air transmission pipeline to be blocked, affecting the hot air transmission. Therefore, a phase change heat storage device for a heating unit is now proposed. Utility Model Content
