Technical Field

[0001] The utility model relates to the technical field of photovoltaic houses, and in particular to a photovoltaic roof and a photovoltaic house. Background Art

[0002] Normally, conventional photovoltaic roof systems that can dissipate heat do not have a waterproof function, while photovoltaic roofs with waterproof functions have poor heat dissipation effects due to their sealing. Specifically, one part is to directly lay photovoltaic tiles on the roof surface, so there is no heat dissipation channel, resulting in poor heat dissipation effects. The other part is to set up supporting structures such as vertical keels and horizontal purlins, but the four circles are sealed and not connected to the outside, resulting in poor heat dissipation effects.

In addition, since the roof surface, the support assembly and the photovoltaic tile group can form a heat dissipation channel, compared with some technologies that separately set up an air duct with heat dissipation holes, the present application does not need to set up an additional air duct structure, and directly defines the air duct between the support assembly and the photovoltaic tile, thereby simplifying the structure.

[0056] In this technical solution, the first heat dissipation window 172 is arranged on the two end faces of the first ridge tile 152 along the width direction of the photovoltaic house 2, so that the overall aesthetics is good. On the other hand, the first heat dissipation window 172 is arranged on the two end faces of the first ridge tile 152 along the width direction of the photovoltaic house 2. In this way, since the first heat dissipation window 172 is arranged in a vertical direction, rainwater will not flow back to the first heat dissipation channel 131 through the first heat dissipation window 172.

[0071] Next, the applicant introduces the photovoltaic roof 1 of the present utility model from another perspective.

[0072] It should be understood that the current photovoltaic roofs that can dissipate heat usually do not have a waterproof function, while the photovoltaic roofs that have a waterproof function have poor heat dissipation, and high temperature affects the power generation efficiency of the system. Based on this, the utility model proposes a photovoltaic roof 1, and a waterproof rubber strip is designed on the photovoltaic tile 122, so that the entire photovoltaic system has a good waterproof function, a heat dissipation channel 13 is designed at the eaves, and heat dissipation windows are designed at other appropriate positions on the roof, so that the entire photovoltaic system has an air convection channel, so that the photovoltaic roof 1 of the utility model has good waterproof performance, the system can dissipate heat, and the reduction in temperature allows the photovoltaic system to have a higher power generation efficiency. Specifically, the design of the photovoltaic roof 1 of the utility model is as follows:

[0073] The photovoltaic roof 1 (the actual photovoltaic roof is relatively complex, and this case takes the simplest structure as an example) is composed of photovoltaic tiles 122, eaves tiles 192, and first ridge tiles 152. The first heat dissipation window 172 is installed on the side of the first ridge tile 152. The entire system is installed on the roof 14 of the building. The size and number of the first heat dissipation window 172 can be determined according to the area of ​​the roof 14.

[0074] During the installation process, the vertical keel (i.e., the first support bar 112 of the present invention) and the transverse purlin (i.e., the second support bar 114 of the present invention) are first installed on the surface of the roof 14, and the transverse purlin is installed on the vertical keel. Air can flow through the gaps below the transverse purlins in the horizontal and vertical directions, and can flow through the gaps above the vertical keels in the horizontal direction.

[0075] In addition, a waterproof rubber strip (also known as the second sealing strip 12292 of the utility model) is designed on the top of the photovoltaic tile 122, and the upper and lower adjacent photovoltaic tiles are overlapped. In addition to realizing the waterproof function, the waterproof rubber strip can also serve as a buffer between the upper and lower adjacent photovoltaic tiles, effectively protecting the photovoltaic tiles 122. The photovoltaic tiles 122 are fixed to the transverse purlins by screws 12294, and frames 1223 are designed on the left and right sides of the photovoltaic tiles 122. The left and right adjacent photovoltaic tiles 122 are overlapped by the frames 1223. The entire roof system has good waterproof functions both horizontally and vertically.

[0076] The air can flow from the eaves all the way to the first ridge tile 152 and be discharged from the first heat dissipation window 172. The circulation of air can effectively reduce the internal temperature of the roof system, improve the power generation efficiency of the photovoltaic tile 122, and reduce the energy consumption inside the building.

[0077] The photovoltaic roof 1 of the utility model has good waterproof performance, the system can dissipate heat, and the reduction in temperature allows the photovoltaic system to have higher power generation efficiency. A channel is designed at the eaves tile 192, and an air blower 18 is designed at other suitable positions on the roof 14. The air blower 18 can accelerate air convection, and large-area air circulation can be completed when the ventilation area is small, with little impact on the appearance of the building.

[0078] like Fig.10 As shown, the second aspect of the utility model provides a photovoltaic house 2, including: a photovoltaic roof 1 as provided in any embodiment of the first aspect of the utility model. Since the photovoltaic house 2 provided by the utility model includes the photovoltaic roof 1 provided in any embodiment of the first aspect of the utility model, it has all the beneficial effects of the photovoltaic roof 1 provided in any embodiment of the first aspect of the utility model.
