Louvre type flat solar collector

technical field

The utility model relates to a building fusion type solar heat collector device which can be installed on building bay windows, window walls, balconies, walls and roofs, in particular to a louver type flat solar heat collector.

Background technique

Solar water heaters bring convenience to home life, improve the quality of life and save energy. The main components of the existing flat-plate solar collectors are: transmission cover plate, heat-absorbing plate, heat insulation layer, pipeline for circulating fluid, shell, etc., and its structure is characterized by a planar board-box structure. The arrangement position of the flat plate heat collector with such a structure is not only limited, but also the effect of combining with the building and decorating it is not ideal. What's more unfavorable is that due to the large plane area of the heat collector, the cover plate reflects light strongly, which will cause serious light pollution and affect the view of the building.

Contents of the invention

The purpose of this utility model is to provide a louver type flat solar collector aiming at the defects in the prior art. There are a series of problems described in the technology.

The technical solution adopted by the utility model to solve the technical problems is: the louver type flat solar heat collector includes a solar heat collecting plate 1 and a header 3, and is characterized in that: the described solar heat collecting plate 1 is composed of row pipes 2, heat-absorbing ribs 4 and insulation jacket layer 5. The solar collector plate 1 is connected to the header pipe 3 through the row pipe 2, and the header pipe 3 is provided with a sealing jacket layer 6 of thermal insulation material.

Compared with the background technology, the utility model has the beneficial effect that: the louver-type flat solar collector and its assembly method adopt multiple sets of tube fins or tube-sheet heat-absorbing plates in a louver-type parallel arrangement structure , each group of heat-absorbing plates has its own independent insulation jacket, and can increase the solar collector area of the heat-collecting area under the same illumination area. Due to the louver-like structure, it can reduce light pollution to nearby buildings and has a relatively Good decorative effect on the appearance of the building; the heat accumulated under the action of the insulation cover is not easy to lose, which is beneficial to the heat collection of the heat absorbing plate. It has high heat collection efficiency, beautiful appearance and convenient installation.

Detailed ways

As shown in Fig. 1, 2, 3, described louver type flat solar heat collector, the louver type flat solar heat collector includes solar heat collecting plate 1 and manifold 3, and it is characterized in that: all The solar heat collector 1 described above is composed of row pipes 2, heat-absorbing ribs 4 and insulation jacket 5, the solar heat collector 1 is connected with the header 3 through the row pipe 2, and the header 3 is provided with a heat-insulating material sealing jacket 6.

The thermal insulation cover layer 5 on the solar thermal collector plate 1 is composed of a single/double layer of transparent material layer 5-1 with strong translucency on the upper part and a thermal insulation material layer 5-2 at the lower part, and the single layer with strong translucency /The double-layer light-transmitting material layer 5-1 and the thermal insulation material layer 5-2 are connected through a buckle groove 11, and a resin sealing layer is provided at the junction of the buckle groove 11. There are a plurality of solar heat collecting plates 1 , and the plurality of solar heat collecting plates 1 are arranged and installed on the header pipe 3 in the form of louvers, and the inclination angle corresponding to each solar heat collecting plate 1 and the horizontal plane is α. The sealing jacket layer 6 of thermal insulation material outside the manifold 3 is provided with a fixing fastener 7, and the fixing fastener 7 is provided with a fixing card 7-1. The header 3 is provided with a water inlet 8 and a water outlet 9 , and the end of the header 3 corresponding to the water inlet 8 and the water outlet 9 is provided with a pipe plug 10 .

In the louver type flat solar collector, the single/double-layer light-transmitting material layer 5-1 with strong light transmission on the upper part of the insulation cover layer 5 can adopt glass fiber reinforced plastic (FRP), methacrylic acid methyl ester (MMA) and glass, etc.; the insulation material layer 5-2 of the lower part can adopt insulation materials such as polyurethane, rock wool, mineral wool, and the surface of the heat-absorbing rib 4 of the solar collector plate 1 is coated/plated with a heat-absorbing material.
