Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor under the premise of the present application, all belong to the scope of protection of the present application.
[0026] It should be noted that: similar numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0029] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.

[0030] Example 1:
[0031] Refer to the attached diagrams in the instruction manual. Figures 1-6 The novel flat-plate thermal storage phase change plate 3 shown includes a phase change plate 3, an outer shell layer for protection surrounding the phase change plate 3, the outer shell layer including an outer shell plate 1 and an encapsulation cover 2, the outer shell plate 1 and the encapsulation cover 2 being tightly connected, an accommodating cavity being provided inside the phase change plate 3, and an adhesive cavity 4 for filling adhesive being separated between the phase change plate 3 and the outer shell layer.
[0032] Brief description of working principle:
[0033] First, adhesive is added to the adhesive cavity 4 to bond the phase change plate 3 and the outer shell plate 1 together. Then, the sealing cover 2 is connected to the outer shell plate 1 to form a sealed whole. Then, the heat absorption and release characteristics of the phase change material are utilized. When the temperature of the microenvironment in which the phase change material is located is lower than the phase change point, the phase change material condenses from liquid to solid, generating heat. When the temperature of the microenvironment in which the phase change material is located is higher than the phase change point, the phase change material melts from solid to liquid, generating heat absorption. Then, the heat generated by electric heating is stored. When the room temperature drops during the day, the heat is released to maintain the room temperature.
[0034] It is worth noting that the flat-plate thermal storage phase change plate 3 in this application can be modularized and used in conjunction with other components. For example, it can be used to manufacture prefabricated floor heating tile modules or for small-area wall heating. During the process of the phase change plate changing from solid to liquid, the overall volume does not change much, thus ensuring the smooth operation of the whole process.
[0035] Example 2:
[0036] As one of the optimized structural designs for Example 1, such as Figures 1-6 As shown, to better connect the outer shell plate 1 and the encapsulation cover 2, the encapsulation cover 2 includes a front cover plate 21 and a snap-fit plate 22. The snap-fit plate 22 is fixed to the end face of the front cover plate 21 facing the opening end of the outer shell plate 1. The opening end of the outer shell plate 1 is also provided with a snap-fit groove 5 that snaps into the snap-fit plate 22, and the snap-fit plate 22 and the snap-fit groove 5 are tightly connected by snap-fit.
[0037] It is worth noting that, in order to facilitate the overall processing of the phase change plate 3, both the outer shell plate 1 and the encapsulation cover 2 are made of PP plastic, aluminum or stainless steel, and the phase change point of the phase change plate 3 is 20-50 degrees Celsius. Taking advantage of the easy processing characteristics of metal and plastic, the materials for making the outer shell plate 1 and the encapsulation cover 2 are selected as PP plastic, aluminum or stainless steel. In actual practice, the material for making the outer shell layer can be selected according to specific needs, thereby making the processing more efficient.
[0038] It is worth noting that, in order to better convert thermal energy, the material encapsulated in the cavity inside the phase change plate 3 is an organic / inorganic phase change material. The operator can select a material with an enthalpy value of 200 kJ / kg or higher based on the actual situation. In summary, the phase change energy storage plate 4 has a phase change point of 20-50 degrees Celsius. On the one hand, during the phase change process, the phase change material can absorb or release heat from the environment, thereby achieving the effect of storing and releasing energy, solving the problem of mismatch between energy supply and demand in time and space, and effectively improving energy utilization. On the other hand, since the phase change temperature of 20-50 degrees Celsius will not cause very low indoor temperatures, it ensures that the phase change material can play its role in regulating room temperature throughout the year, effectively improving the comfort of the indoor environment.
[0039] Example 3:
[0040] This embodiment is a further optimization based on the structure and principle of Embodiment 1 or Embodiment 2, such as... Figures 1-6 As shown, in order to better encapsulate the phase change material and prevent leakage, the encapsulation method in the containment cavity is microencapsulation or encapsulation with porous aggregate as the carrier of the phase change material. The adhesive added to the adhesive cavity 4 is epoxy adhesive or polyurethane adhesive. The adhesive can be selected according to the actual situation, using epoxy adhesive or polyurethane adhesive, or other materials of adhesive.
[0041] It's worth noting that there are currently two methods for applying phase change energy storage technology to the energy-saving field. One method combines phase change materials with insulation materials, utilizing the heat absorption and release characteristics of the phase change materials to block heat flow, thus adding thermal resistance and increasing the thermal inertia of the insulation material, working together to achieve thermal insulation. The other method fully utilizes the sensitivity of phase change materials to changes in ambient temperature. When used in indoor environments, changes in indoor temperature trigger a phase change in the phase change material, causing it to release or absorb heat from the environment, thus acting as a temperature damper and automatically regulating indoor temperature. Both methods can be applied to mitigate indoor temperature fluctuations and prolong the time spent maintaining a comfortable indoor temperature, thereby reducing the frequency of air conditioning or heating system operation, achieving the goal of automatically regulating indoor temperature and reducing energy consumption.
[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
