Description
Technical Field
The utility model relates to a solar energy application technology field, concretely relates to be favorable to slope roofing building to implement the less flat plate solar collector of thickness size of solar equipment integrated installation.
Background
Solar building integration is the technological progress and development direction of solar equipment applied to building energy conservation. At present, the solar heat collector suitable for building integrated installation is mainly a flat-plate solar heat collector. For a flat-plate solar collector, a common building integrated installation mode is related to a roof structure type, for example, a flat roof is supported and installed by using a steel structure support with a certain inclination angle, and an inclined roof is installed by using an embedded type. Although the mosaic mounting process can enable the roof on which the solar equipment is mounted to be flat and attractive, the mosaic mounting process needs to be specially matched with the roof structure of a building, the complexity, the construction difficulty and the engineering construction cost of the roof structure are increased to a great extent, the risk of roof water leakage is increased, and the mosaic mounting process is obviously not suitable for being applied to existing inclined roof buildings.
The flat-plate solar collector mainly comprises a shell, a glass light-transmitting cover plate, heat-insulating plates on the periphery and the back of the flat-plate solar collector and a heat-absorbing plate core arranged inside the heat-insulating plates, wherein the heat-absorbing plate core comprises a heat-absorbing plate and runner pipes arranged on the heat-absorbing plate, the runner pipes of the existing flat-plate solar collector are mainly manufactured by welding collecting pipes and calandria, and the thicker collecting pipes and the traditional product structural design determine that the thickness of the flat-plate solar collector is larger and is generally 70-100 mm. When the thicker heat collector is directly installed on the existing inclined roof, the thicker heat collector is easily damaged by wind and rain, and equipment obviously protruding out of the roof can damage the appearance of a building and cannot meet the requirement of aesthetic specification.
SUMMERY OF THE UTILITY MODEL
To the defect among the prior art, the utility model provides a less flat plate solar collector of thickness size implements solar equipment integrated installation for slope roofing building and creates the advantage.
The scheme of the utility model is that:
the utility model provides a flat-plate solar collector, includes frame, backplate, heat preservation, absorber plate core and glass apron, the backplate is installed the bottom of frame, heat preservation and absorber plate core set gradually backplate upper portion, glass apron cover are at the frame top, and the absorber plate core includes the absorber plate and fixes the runner pipe on the absorber plate, its characterized in that: the upper surface of the heat preservation layer is provided with a groove matched with the runner pipe, the runner pipe is embedded into the groove, and a heat reflection layer is arranged between the heat preservation layer and the heat absorption plate core or between the heat preservation layer and the back plate. The runner pipe on the heat absorption plate core is embedded into the heat insulation layer, so that the overall thickness size of the flat-plate solar collector can be reduced to the maximum extent. The heat loss is likely to be increased due to the pure thickness reduction, so that the heat reflecting layer is arranged between the heat insulating layer and the heat absorbing plate core or between the heat insulating layer and the back plate, a part of heat dissipated from the heat absorbing plate core is reflected back, and the heat efficiency index of the product is ensured on the premise of reducing the thickness size of the flat-plate solar collector.
More specifically, the distance between the glass cover plate and the upper surface of the heat absorbing plate core is 20-30 mm. The distance between the glass cover plate and the heat absorption plate core is too close and too far, so that heat loss is larger, and the distance provided by the scheme can ensure higher heat efficiency.
More specifically, the heat-insulating layer is made of foamed plastics such as foamed polyurethane or foamed rubber-plastic molding plates. The heat reflecting layer is a film covered with a reflecting heat-insulating coating, such as a vacuum aluminized plastic film, and is used for reflecting heat dissipated by the heat absorbing plate core in a heat radiation mode.
The utility model provides a solar energy flat plate collector makes its thickness littleer under the prerequisite of guaranteeing the thermal efficiency through the improvement of structure, when installing on current oblique roofing, especially flat plate solar collector when the laminating formula installation is implemented to the roofing to one side, and more pleasing to the eye standard has reduced the risk that the wind and rain harmd, has created more ideal condition for solar water heater building integration installation.
