[0018] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0019] The first embodiment of the present application is as follows:
[0020] Please refer to Figure 1 and Figure 2 wherein Figure 1 is a schematic structural diagram of the overall self-insulating brick with a thermal insulation structure,Figure 2 It is a sectional view of the brick body 101.
[0021] The utility model provides a self-insulating brick with a heat-insulating structure, which includes a brick body 101, a heat-insulating structure and a positioning structure. The heat-insulating structure includes cavities 102 and heat-insulating filling materials 103. The brick body 101 also has long cavities 104 and rib walls 105. The brick body 101 also has supplementary holes 106. Through the foregoing solution, the problem that existing heat-insulating bricks usually achieve heat insulation by setting a porous structure inside to block heat transfer, but the effect of the existing porous structure on heat insulation is very limited, resulting in an unsatisfactory overall heat-insulating effect during actual use is solved.
[0022] For this specific embodiment, the cavities 102 are arranged inside the brick body 101, the heat-insulating filling materials 103 are arranged inside the cavities 102, and the long cavities 104 are arranged on one side of the cavities 102 inside the brick body 101; the rib walls 105 are located on one side of the long cavities 104, and the supplementary holes 106 are located on one side of the long cavities 104. Starting from the theoretical analysis of the heat transfer process of the perforated brick, this solution analyzes the thermal performance parameters affecting the perforated brick, and from factors such as the hole shape, key hole dimensions, arrangement method, number of rows and columns, porosity, perforated brick material and filling material of the perforated brick, and designs perforated bricks with different parameters under the condition of meeting relevant national standards and specifications. Computer technology is used to establish a model for simulation, and the equivalent thermal conductivity of various perforated bricks is obtained to analyze the thermal performance differences of different perforated bricks. Then, the perforated brick with the most ideal simulated performance is selected for production. The heat transfer coefficient of the perforated brick wall is tested through experiments in the laboratory. Through the comparative analysis of the simulation and experimental research of the perforated brick wall, the key factors affecting the thermal performance of the perforated brick wall are studied, the technical barriers are broken through, and a new type of low-carbon self-insulating perforated brick suitable for use in this region is developed, with a heat transfer coefficient reaching 0.9 - 1.0 W / ㎡·K. The main materials of the brick body 101 are inorganic silicate materials, shale and quartz tailings sand. Then, it is formed by vacuum high pressure and sintered at a high temperature above 1000℃. Finally, the sintering is completed. A plurality of cavities 102 are arranged inside the brick body 101, and each cavity 102 is filled with the heat-insulating filling material 103. A plurality of long cavities 104 are distributed on both sides of the cavity 102, and the rib walls 105 are located between the plurality of long cavities 104 and the cavity 102. The long cavities 104 are strip-shaped, and the supplementary holes 106 are distributed on the upper and lower sides of the long cavities 104. By providing the supplementary holes 106, it is possible to avoid the situation that the inside of the brick body 101 is hollow and the structure is unstable due to the overly long strip holes inside the brick body 101 while maximizing the porous structure inside the brick body 101.
[0023] When the self-insulating brick with a thermal insulation structure in this embodiment is in use, the thermal insulation filling material 103 is arranged in the cavity 102 provided in the middle of the brick body 101. According to the heat transfer direction, heat is conducted from the outside to the inside through the rib walls 105 on the four sides of the cavity 102. The lower heat transfer coefficient is composed of a combination of three methods. One is to increase the aspect ratio of the holes, that is, the long holes 104 provided in the brick body 101, so that the heat conduction path is lengthened, promoting an increase in thermal resistance. The second is to reduce the cross-sectional size of the transverse rib walls 105. The third is to fill the cavity 102 with thermal insulation materials, resulting in a reduction in the heat directly transmitted through the solid, and using the thermal resistance of the material itself to reduce the heat transfer rate, ultimately achieving the calorific value of the expected heat transfer coefficient, realizing that the heat transfer rate can be better reduced through the provided thermal insulation structure, and then achieving the calorific value of the expected heat transfer system.

The positioning structure provided by the present invention includes a positioning long platform 201 and a mating groove 202, and the positioning long platform 201 is provided with an inclined surface 203.
[0026] Among them, the positioning long platform 201 is arranged on the outer side of the brick body 101; the mating groove 202 is located on the outer side of the brick body 101, the inclined surface 203 is arranged on the surface of the positioning long platform 201, a total of four positioning long platforms 201 are distributed on the upper and lower sides of the brick body 101, and four mating grooves 202 are distributed on the left and right sides of the brick body 101. Each positioning long platform 201 is provided with the inclined surface 203 on its surface. The positioning long platform 201 provided on the brick body 101 matches the shape and size of the mating groove 202 provided on the side of the brick body 101, enabling users to quickly and effectively position when stacking and building multiple brick bodies 101 through the cooperation of the positioning long platform 201 and the mating groove 202. When positioning, the inclined surface 203 provided on the surface of the mating groove 202 can guide the subsequent cooperation of the positioning long platform 201 and the mating groove 202 when the positioning long platform 201 is offset to a certain extent.
[0027] When using a self-insulating brick with a heat-insulating structure according to this embodiment, positioning is carried out through the positioning long platforms 201 and the mating grooves 202 provided on the upper and lower sides and the left and right sides of the brick body 101 when a plurality of the brick bodies 101 are stacked and built, making it more convenient during actual operation and greatly enhancing the practicality of the entire device.
