Description

Technical Field

[0001] The utility model relates to the technical field of roof construction, in particular to a metal roof system with a solar energy heat collection function. 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 temperature of the metal plate surface is higher than the surface temperature 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 roofs 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 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.

[0008] As a preferred solution of the utility model, the heat collector is a closed hollow box or hollow tube, the heat collector is filled with heat collection circulation liquid, the heat collector is one or more in series, the series heat collectors are connected in series through connecting pipes and connected to the circulation pipeline. One or more pressed grooves are set in the middle of the metal roof panel body of this solution.

[0011] As a preferred solution of the utility model, the connection between the heat collector and the metal roof panel body adopts a groove clamp connection, or a mechanical fixed connection by welding, buckles, pressure blocks, pressure strips or clamps. The groove clamp of this solution is embedded in the press-formed groove of the metal roof panel body, and the groove clamp can be clamped into the heat collector, so that the position of the heat collector is fixed; the heat collector can also be fixed by mechanical means such as welding, buckles, pressure blocks, pressure strips or clamps.

[0012] As a preferred solution of the utility model, the connection between the heat collector and the metal roof panel body is non-fixed and freely placed. On a flat roof or a roof with a small slope, the heat collector and the metal roof panel body of this solution may not be fixed, and their position is limited by the connection structure with the circulation pipeline.
