For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] To this end, the following solutions are proposed:

[0029] See also Figure 1 The present invention provides a temperature-regulating, earthquake-resistant and energy-saving brick 100, comprising a brick body 101 and a plurality of straight tubes 102 embedded in the brick body 101, the straight tubes 102 are filled with a phase change material 103, and both ends of the straight tubes 102 are sealed with sealing materials 104 to prevent the phase change material 103 from leaking during use.

[0030] As a preferred embodiment of the present invention, the brick body 101 used is a silicate cement-based material, such as general silicate cement that meets national standards, or a cement-based composite material with special functions such as durability, fire resistance, and heat preservation, which is not specifically limited here.

[0031] As a preferred embodiment of the present invention, the straight pipe 102 is a steel pipe. In the present invention, the straight pipe 102 made of steel is embedded in the brick body 101, which can enhance the anti-seismic performance of the brick body 101, and make the brick body 101 have higher compressive and shear strength, thereby enhancing its compressive strength and anti-seismic performance.

[0032] As a preferred embodiment of the present invention, the phase change material 103 used is a solid-liquid organic phase change material. As common knowledge, phase change materials (PCM) absorb or release a large amount of heat during the phase change process, which can realize the storage and utilization of thermal energy. According to the phase change form, it can be divided into solid-solid phase change, solid-liquid phase change, solid-gas phase change and liquid-gas phase change. Among them, solid-liquid phase change is a more commonly used phase change form. Solid-liquid phase change can also be divided into organic phase change materials and inorganic phase change materials. Solid-liquid organic phase change materials have become a commonly used phase change material because of their good energy storage effect and convenience of use. The phase change material 103 of the present invention adopts this widely used solid-liquid organic phase change material, such as paraffin, fatty acid, fatty acid ester or alcohol compound. Usually, the paraffin is paraffin with a melting point of 20-60°C, the fatty acid is dodecanoic acid, tetradecanoic acid, pentadecanoic acid, palmitic acid or stearic acid, etc., and the alcohol compound is dodecanol, tetradecanoic acid, hexadecanol, octadecanoic acid or polyethylene glycol with a molecular weight of 2000-20000, etc.

[0033] In the present invention, the phase change material 103 is filled in the straight tube 102, and the phase change material is used to absorb or release a large amount of heat during the phase change process. Figure 2 As shown, when the external environment temperature is high (for example, during the day), reaching or exceeding the melting temperature of the solid-liquid organic phase change material 103, the phase change material 103 changes from solid to liquid, absorbing and storing a large amount of latent heat during the phase change process, and storing the heat energy in the environment in the phase change material 103, so that the heat of the high temperature environment enters the room more slowly, thereby achieving the purpose of lowering the indoor temperature; Figure 3As shown, when the external environment temperature is low (for example, at night), the phase change material 103 changes from liquid to solid, and the heat stored in the solid-liquid organic phase change material 103 is released, so that the heat from the low temperature environment is lost more slowly when entering the room, thereby having a heat preservation effect on the room.

[0034] Figure 4 A comparison chart is given of the temperature-adjustable earthquake-resistant energy-saving bricks (containing PCM) and pure cement bricks (excluding PCM) of the present invention, using xenon lamps to heat and measuring the inner wall temperatures of the two bricks by thermocouples. Figure 4 It can be seen that compared with pure cement bricks without PCM, the temperature-adjusting, earthquake-resistant and energy-saving bricks containing PCM of the present invention have lower inner wall temperature at high temperature and higher inner wall temperature at low temperature, which reflects the difference in thermal performance of the two bricks in practical applications.

[0035] In the present invention, in order to prevent the phase change material 103 from leaking during use, sealing materials 104 are sealed at both ends of the straight tube 102. As a specific implementation, the sealing material 104 is, for example, silicone sealant.

[0036] Figure 5 The actual picture of the temperature-adjusting, earthquake-resistant and energy-saving bricks according to the present invention during the manufacturing process is given. In the manufacturing process, the straight tube 102 sealed with the phase change material 103 is firstly Figure 5 As shown, it is pre-buried in cement slurry, and the cement slurry is poured into a rectangular parallelepiped mold. After solidification, the temperature-adjusting, earthquake-resistant and energy-saving brick 100 of the present invention is formed.

[0037] As a preferred embodiment of the present invention, Figure 1 As shown, the brick body 101 of the temperature-regulating, earthquake-resistant and energy-saving brick 100 of the present invention is a rectangular parallelepiped, and a plurality of straight tubes 102 are arranged in parallel inside the brick body 101. A single straight tube 102 extends along the length direction or the width direction of the brick body 101, and the straight tube 102 is located on one side of the brick body 101 in the thickness direction of the brick body 101. That is, in the temperature-regulating, earthquake-resistant and energy-saving brick 100 of the present invention, the straight tube 102 is not located in the middle of the brick body 101 in the thickness direction of the brick body 101.

[0038] The present invention further provides a temperature-adjustable, earthquake-resistant and energy-saving building wall, comprising the modular temperature-adjustable, earthquake-resistant and energy-saving bricks 100 as described above, wherein the thickness direction of the temperature-adjustable, earthquake-resistant and energy-saving bricks 100 is the thickness direction of the temperature-adjustable, earthquake-resistant and energy-saving building wall.

[0039] Figure 6 A schematic diagram is given of the temperature-adjusting, earthquake-resistant and energy-saving brick 100 of the present invention used as a temperature-adjusting, earthquake-resistant and energy-saving building wall, in which the phase change material 103 is arranged in the brick body 101 in three ways: close to the interior, in the middle and close to the outdoors. Figure 7 Based on the climatic conditions of Chongqing Figure 6 Comparison of the test results of the inner wall heat flux density for the three cases plus the case without phase change material.

[0040] from Figure 6 and Figure 7 It can be seen that the position of the phase change material 103 in the brick body 101 is close to the outdoor and is close to the thermal performance temperature curve of the pure cement brick without PCM. The thermal performance temperature curves of the two arrangements of the phase change material 103 in the brick body 101 close to the indoor and in the center are significantly better than the position of the phase change material 103 in the brick body 101 close to the outdoor and the pure cement brick without PCM. Compared with the arrangement of the phase change material 103 in the brick body 101 in the center, the thermal performance temperature of the phase change material 103 in the brick body 101 close to the indoor is even better.

[0041] Therefore, in the present invention, the temperature-regulating earthquake-resistant energy-saving brick 100 of the present invention is used as a temperature-regulating earthquake-resistant energy-saving building wall, and the thickness direction of the temperature-regulating earthquake-resistant energy-saving brick 100 is the thickness direction of the temperature-regulating earthquake-resistant energy-saving building wall, wherein the straight tube 102 filled with phase change material 103 in the temperature-regulating earthquake-resistant energy-saving brick 100 is arranged on the side close to the brick body 101 and is arranged on the side of the temperature-regulating earthquake-resistant energy-saving wall facing the interior. This arrangement can obtain the best thermal performance during actual use.

[0042] The present invention provides a temperature-regulating, earthquake-resistant and energy-saving brick and a temperature-regulating, earthquake-resistant and energy-saving building wall including the energy-saving brick. By embedding a plurality of straight tubes filled with phase change material inside the brick body, the use of the phase change material can naturally adjust the internal temperature of the building by absorbing and releasing heat under different climatic conditions, thereby improving the overall heat storage performance of the brick body as a whole and effectively improving the thermal efficiency of the building. At the same time, pre-embedding a plurality of straight tubes filled with phase change material in the brick body can also improve the overall earthquake resistance and structural safety of the building wall.

[0043] In addition, the temperature-adjusting, earthquake-resistant and energy-saving bricks of the present invention also have the following advantages:

[0044] (1) Energy saving and environmental protection: The temperature regulation function of phase change materials can reduce the energy consumption of building air conditioning systems, meeting the requirements of green buildings;

[0045] (2) Convenient construction: The modular design of the brick structure of the temperature-adjusting, earthquake-resistant and energy-saving bricks facilitates quick installation, reduces the amount of building materials used and improves construction efficiency;

[0046] (3) Fireproof performance: The brick materials, phase change materials and sealing materials of temperature-controlled earthquake-resistant energy-saving bricks can be specially treated by adding flame retardants to make them have good fireproof performance, thereby improving the overall fire safety of the temperature-controlled earthquake-resistant energy-saving building walls.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
