Description

Technical Field

[0001] This disclosure relates to the field of terminal technology, and in particular to a heat collection wall. Background Technology

[0002] Against the backdrop of persistently high energy consumption and increasingly severe carbon emissions in the building sector, and the continuous development of renewable energy building technologies, the potential for promoting solar building technologies in the field of building energy conservation and emission reduction is becoming increasingly significant.

[0003] In some related technologies, gravity heat pipes are used to regulate the heat input into the room. However, the evaporation section of the gravity heat pipe has static heat collection performance under various seasons or weather conditions. That is, the surface of the evaporation section usually has a high emissivity in the solar radiation band. This will cause the composite wall system to rely mainly on solar heat collection throughout the year, resulting in poor adaptability and low flexibility of the heat collection wall. Utility Model Content

[0017] As can be seen from the above embodiments, this disclosure improves the flexibility of the heat collection wall in regulating the heat collection according to the environment by adjusting the emissivity of the thermochromic coating, adjusting the transmittance of the thermochromic layer, and integrating the power generation layer. This enhances the adaptability of the heat collection wall in complex climate regions and expands the application areas of the heat collection wall.

These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0029] Figure 1 This is a schematic diagram illustrating the assembly of a heat-collecting wall with a building wall according to an exemplary embodiment. Figure 2 yes Figure 1 Decomposition diagram Figure 3 This is a schematic cross-sectional view of a heat-collecting wall according to an exemplary embodiment. For example... Figures 1-3 As shown, the heat collection wall includes a gravity heat pipe 1, a thermochromic coating 2, and a glass cover plate 3. The gravity heat pipe 1 can be installed in the building wall. For example, the gravity heat pipe 1 can be fixed to the building wall by adhesive, locking, or snap-fitting, and cannot move relative to the building wall. The number of gravity heat pipes 1 can be single or multiple, such as... Figure 1 The multiple gravity heat pipes 1 shown can be arranged side by side on the building wall in the same manner, or they can be arranged on the building wall in their own manner. This disclosure does not impose any restrictions on this.

[0030] Thermochromic coating 2 is applied to the evaporation section of each gravity heat pipe 1. Within a set temperature range, the emissivity of the thermochromic coating 2 is inversely proportional to its surface temperature; that is, the lower the surface temperature of the thermochromic coating 2, the higher its emissivity. It can be understood that when the surface temperature of the thermochromic coating 2 is low, the gravity heat pipe 1 is in a relatively low ambient temperature. At this time, the building typically has a high heating demand. The thermochromic coating 2, exhibiting high emissivity, helps absorb solar radiation and convert it into heat energy, which is then transferred to the indoor space through the conduction of the gravity heat pipe 1 to meet the indoor heating demand. However, in hot weather conditions such as summer, if heat is continuously passively absorbed through the gravity heat pipe 1, excessive heat will be conducted into the room, increasing the building's cooling load and negatively impacting indoor thermal comfort. The increase in ambient temperature can also be reflected in the increase in the surface temperature of the thermochromic coating 2. Consequently, the emissivity of the thermochromic coating 2 decreases, which can effectively reduce the absorption of solar radiation and heat conduction, thereby reducing the operating load of the building air conditioning system, alleviating the pressure on air conditioning energy consumption, and ultimately achieving the goal of building energy conservation.

[0031] The glass cover 3 can cover the evaporation section of the gravity heat pipe 1, and the glass cover 3 includes a power generation layer 31 and a color-changing layer 32, which are stacked between the power generation layer 31 and the color-changing layer 32, with the color-changing layer 32 facing the thermochromic coating 2. At least one of the layers between the color-changing layer 32 and the power generation layer 31 is glass. The glass cover 3 can be connected to the building wall via a frame, and the transmittance of the color-changing layer 32 can be adaptively adjusted according to the outdoor ambient temperature.

[0032] For example, such as Figure 4 As shown, the color-changing layer 32 may include a thermochromic layer. When the outdoor ambient temperature is relatively high, the thermochromic layer can be in a low transmittance state, reducing the amount of solar radiation entering, reducing the heat collection in the evaporator section, preventing excessive heat from entering the room, and reducing the cooling load in summer; for example... Figure 5 As shown, when the outdoor ambient temperature is low, the thermochromic layer can be in a high transmittance state, allowing more solar radiation to pass through, enhancing the heat collection of the evaporation section of the gravity heat pipe 1, and thus allowing more heat to be transferred into the room through the heat pipe to meet the winter heating needs.

[0033] For example, the color-changing layer 32 may include an electrochromic layer, the transmittance of which can change with voltage. For instance, in high-temperature environments, the color-changing layer 32 can be adjusted to a low-transmittance state, and in low-temperature environments, it can be adjusted to a high-transmittance state. Compared to thermochromic layers, electrochromic layers allow for active adjustment of the transmittance of the color-changing layer 32, enabling flexible control of its transmittance according to actual needs.

[0034] A power generation layer 31 can be integrated on the glass cover plate 3, for example, a photovoltaic module can be integrated. Figure 6 As shown, some energy can reach the thermochromic coating 2 after passing through the power generation layer 31 and the color-changing layer 32; some energy can be absorbed by the power generation layer 31 and converted into electricity; and some energy will be reflected back into the air. The integrated design of the power generation layer 31 ensures that a certain proportion of solar radiation passes through the glass cover plate 3 to reach the surface of the evaporation section to meet the heat collection and heat transfer requirements of the gravity heat pipe to the interior, while utilizing the photovoltaic effect to convert solar energy into electrical energy and store it to compensate for building energy consumption.

[0035] In this embodiment, by adjusting the emissivity of the thermochromic coating 2, adjusting the transmittance of the color-changing layer 32, and integrating the power generation layer 31, the flexibility of the heat collection wall in regulating the heat collection according to the environment is improved, the adaptability of the heat collection wall in complex climate regions is enhanced, and the application areas of the heat collection wall are expanded.

[0036] In some embodiments, the power generation layer 31 may include photovoltaic glass, and the color-changing layer 32 includes a color-changing coating applied to the emitting surface of the power generation layer 31, such as a thermochromic coating or an electrochromic coating. This design is beneficial for increasing the power generation of the power generation layer 31.

[0037] In some embodiments, the color-changing layer 32 may include a glass color-changing layer, which is bonded to the power-generating layer 31. For example, the power-generating layer 31 may be photovoltaic glass, which is bonded to the glass color-changing layer. Alternatively, the power-generating layer 31 may be a non-glass power-generating film layer, which is bonded to the glass color-changing layer. This helps to reduce the thickness of the glass cover plate 3.

[0038] In some embodiments, the color-changing layer 32 may include a glass color-changing layer, the power generation layer 31 may include photovoltaic glass, and a glass cover plate with a cavity may be stacked between the glass color-changing layer and the photovoltaic glass, thereby increasing the strength of the glass cover plate 3.

[0039] In the above embodiments, the projected overlapping areas between the power generation layer 31 and the color-changing layer 32 may be equal or unequal, and can be adapted to meet the overall transmittance requirements of the glass cover plate 3.

[0040] In some embodiments, the evaporation sections of multiple gravity heat pipes 1 can be laid flat to avoid obstruction between gravity heat pipes 1, which is beneficial to increase the heat collection area of ​​the evaporation section. Based on the same heat collection requirements and system parameters, it is beneficial to reduce the number of gravity heat pipes 1 required.

[0041] In the above embodiments, one or more of the gravity heat pipes 1 have at least one bend to facilitate adaptation to the structure of the building wall. This bend can be an arc or a vertical bend. For example, any one of the gravity heat pipes 1 can be arranged in an L-shape, I-shape, W-shape, E-shape, [-shape, or Z-shape. The specific design can be adapted to the actual needs of the building wall.

[0042] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.
