Description

Technical Field

[0001] The utility model relates to the technical field of roof construction, in particular to a metal roof panel with a solar energy heat collection cavity. Background Art

[0002] Metal roofing system is a roof enclosure technology commonly used in large industrial buildings and public buildings. It has the characteristics of large area and wide application. The roof has a large area of ​​sunlight, long time and good angle. Usually, metal roof panels have high heat absorption characteristics under sunlight. The surface temperature of metal roof panels is higher than that of general concrete roofs, roll roofs and other roofs, resulting in poor thermal insulation and energy-saving performance of metal roof systems.

[0003] Lowering the surface temperature of metal roof panels under sunlight can improve the thermal insulation performance of the building envelope system, reduce building energy consumption, and improve energy-saving effects. The heat energy on the surface of the metal roof is collected through a heat collector and circulated and converted to provide a new clean energy for the operation of the building to reduce the energy consumption of the building operation. Metal roof light and heat collection and energy conversion will be a new low-carbon, energy-saving innovative technology.

[0004] Ordinary metal roof panels only serve as building structural functions such as waterproofing, heat insulation, wind resistance, and sound insulation. Giving the roof panels the function of collecting solar and thermal energy and providing clean energy to the building is the main research direction and implementation path for achieving low-carbon and green buildings. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

In this solution, a heat collection cavity is arranged in the flat plate area in the middle of the metal roof panel body. The heat collection cavity is formed by an open box body buckled on the surface or bottom of the flat plate in the middle of the metal roof panel body, and then welded and sealed, so as to form a heat collection cavity in the open box body. The heat collection cavity is filled with a flowable heat collection circulating liquid. In this way, when the open box body and the metal roof panel body are exposed to sunlight, the heat can be transferred to the heat collection circulating liquid, and then the heat collection circulating liquid flows in the matching circulation pipeline to transfer the heat to other heat exchange facilities, thereby reducing the roof temperature; at the same time, the open box body is welded on the metal roof panel body, which increases the rigidity and strength of the roof panel here.

[0008] As a preferred solution of the utility model, the heat collection cavity is provided with a liquid inlet interface and a liquid outlet interface, and the liquid inlet interface and the liquid outlet interface are respectively connected to the external circulation pipeline.

[0009] As a preferred solution of the utility model, the open box body is formed by enclosing metal plates, the metal plates are steel plates, copper plates or aluminum plates, and the thickness of the metal plates is 0.5 mm to 1.5 mm.

[0010] As a preferred solution of the utility model, a plurality of heat collection cavities are provided in the middle of the metal roof panel, the plurality of heat collection cavities are connected by series pipes and communicated with the circulation pipeline, and the connecting pipes are respectively connected to the liquid inlet interface and the liquid outlet interface of the heat collection cavity.

[0011] As a preferred solution of the utility model, the plate rib connection area of ​​the metal roof panel body is the area where two adjacent metal roof panel bodies are connected, and the connection method is overlap, bite, crimp or weld. The plate rib connection area is connected to the roof structure through screws and supports.

[0012] This solution realizes the function of solar thermal energy collection on the basis of waterproof and wind-resistant properties of metal roof panels. It is an innovative metal roof panel with energy-saving function. The heat radiation of the roof is passed through the cavity roof panel, and the surface temperature of the building roof is reduced through liquid circulation, so that the thermal insulation performance of the roof is improved and the energy consumption of building operation is reduced. The radiant heat energy of the roof is converted into hot water and air-conditioning required for building operation through the heat collection and circulation system of the cavity roof panel and the heat conversion equipment, thereby reducing the energy consumption of building operation. A spatial cavity is formed at the bottom of the roof panel through welding, which improves the rigidity of the bottom of the roof panel and improves the overall strength of the roof panel.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the metal roof has the function of collecting light and thermal energy on the basis of being waterproof and wind-resistant, thereby improving the thermal insulation performance of the roof, providing clean energy for building operations, and improving the overall stiffness of the roof panel.
