Description

Technical Field

[0001] This utility model relates to building components, and more particularly to a photoelectric and heat-generating tile. Background Technology

[0002] Currently, building energy conservation and renewable energy utilization are receiving increasing attention. Photovoltaic-thermal (PVT) integrated technology, as an important method for comprehensive solar energy utilization, has been gradually applied to building roofing systems. Existing PVT modules mostly adopt a single-panel structure, with panels connected by external pipes to achieve solar-thermal circulation. However, this type of structure has the following significant shortcomings:

[0003] 1. Leaks are prone to occur at connection points due to long-term thermal expansion and contraction, as well as wind and rain erosion, affecting system reliability. 2. The single-panel structure has poor thermal insulation performance, resulting in significant heat loss and low photothermal conversion efficiency. Summary of the Invention

The heat energy generated by the photovoltaic silicon panels is transferred to the stainless steel threaded underfloor heating pipes below through the heat-conducting liner for heat recovery.

[0008] Furthermore, the vacuum spacer is either evacuated or filled with inert gas.

[0009] Furthermore, the thermally conductive liner is made of metal.

[0010] Furthermore, the photovoltaic silicon panel is attached to the upper surface of the thermally conductive liner using thermally conductive adhesive.

[0011] Furthermore, the glass panel is high-transmittance ultra-white tempered glass.

[0012] Furthermore, the photovoltaic and solar thermal tiles are applied to a roof system, which includes multiple photovoltaic and solar thermal tiles and stainless steel threaded underfloor heating pipes laid on the roof; the multiple photovoltaic and solar thermal tiles are spliced ​​together and cover the stainless steel threaded underfloor heating pipes to form a roof surface layer that has both power generation and heating functions.

[0013] Compared with the prior art, this utility model has the following advantages.

[0014] The photovoltaic and photothermal tile provided by this utility model achieves a high degree of integration and structural optimization of photovoltaic and photothermal functions by multi-layer composite encapsulation of photovoltaic silicon panels, vacuum frames, glass panels and heat-conducting lining plates, and pre-laying stainless steel threaded underfloor heating pipes on the roof.

[0023] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0024] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The singular forms “a,” “the,” and “the” as used in the embodiments of this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0025] Depending on the context, words such as “if” or “suppose” used here can be interpreted as “when”, “in response to determination”, or “in response to detection”.

[0026] For ease of understanding, the embodiments of this disclosure will be described in detail first.

[0027] like Figure 1-6 As shown, the photovoltaic-thermal tile includes, from bottom to top, a heat-conducting liner 2, a photovoltaic silicon panel 1, a vacuum frame 3, a glass panel 4, and an outer frame 5 for encapsulating and fixing each layer. The vacuum frame 3 is sealed to the lower surface of the glass panel 4 and the upper surface of the photovoltaic silicon panel 1 with heat-insulating adhesive, forming a hollow sealed cavity with a vacuum inside. The photovoltaic-thermal tile is laid on top of the stainless steel threaded underfloor heating pipes pre-installed on the roof. The heat energy generated by the photovoltaic silicon panel 1 is transferred to the stainless steel threaded underfloor heating pipes below it through the heat-conducting liner 2 for heat recovery. Specifically, this utility model adopts an integrated encapsulation structure, eliminating the pipe fittings connecting the panels in the traditional PVT system, fundamentally preventing leakage problems caused by sealing failure at the connection points, and improving the reliability of use.

[0028] Preferably, the vacuum frame 3 is evacuated or filled with inert gas to form a sealed vacuum cavity, which effectively prevents heat loss and improves the heat preservation effect, thereby increasing the efficiency of photothermal conversion and transfer.

[0029] In one possible embodiment, the heat-conducting liner 2 is made of metal. While the photovoltaic silicon panel generates electricity, the heat generated is transferred to the underfloor heating pipes through the heat-conducting liner, significantly improving the overall heat utilization rate. The heat-conducting liner 2 is preferably made of aluminum or copper, with a thickness between 1.0 and 2.0 mm. Its surface can be anodized to enhance corrosion resistance. In practice, the heat-conducting liner 2 is in close contact with the stainless steel threaded underfloor heating pipes using thermal paste or metal clips to ensure unobstructed heat conduction.

[0030] In another possible embodiment, the photovoltaic silicon panel 1 is attached to the upper surface of the thermally conductive backing plate 2 with thermally conductive adhesive. The thermally conductive adhesive is a two-component epoxy thermally conductive adhesive or a silicon-based thermally conductive adhesive. The coating thickness is controlled at 0.1~0.3mm, and air bubbles are avoided as much as possible to avoid affecting the thermal conductivity.

[0031] Preferably, the glass panel 4 is high-transmittance ultra-white tempered glass.

[0032] Preferably, the photovoltaic and solar thermal tiles are applied to a roof system, which includes multiple photovoltaic and solar thermal tiles and stainless steel threaded underfloor heating pipes laid on the roof. Multiple photovoltaic and solar thermal tiles are spliced ​​together and cover the stainless steel threaded underfloor heating pipes, forming a roof surface layer that combines power generation and heating functions. Specifically, the heat collection function is achieved by laying stainless steel threaded underfloor heating pipes on the roof, with the photovoltaic and solar thermal tiles covering the pipes during installation. That is, the photovoltaic and solar thermal tiles can be used directly as roof surface tiles, replacing traditional roofing materials and combining building envelope, power generation, and heating functions.

[0033] Another possible implementation, in actual construction, involves laying stainless steel threaded underfloor heating pipes in a serpentine or herringbone pattern on the roof structure layer. The pipe diameter can be DN10~DN16, and the spacing can be adjusted according to the heat load requirements. The photovoltaic and solar thermal tiles are spliced ​​together by the clips or sealing strips of the outer frame 5 to form a continuous, waterproof roof covering layer.

[0034] Another possible embodiment, which is a specific roof system embodiment, is that multiple photovoltaic and solar thermal tile bodies 6 are laid on a roof target plate 8 pre-installed with stainless steel threaded underfloor heating pipes. The target plate serves to fix the underfloor heating pipes and distribute the heat evenly in the horizontal direction. A water trough 7 is provided below the splicing point between the photovoltaic and solar thermal tile bodies 6. The water trough is used to collect rainwater from the roof to achieve drainage.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
