Further, the first end of reflecting piece is connected on base by securing member, and the first end of reflecting piece is towards the first end of thermal-collecting tube, and the second end of reflecting piece is towards the second end of thermal-collecting tube.
Further, multiple reflecting piece is arranged in circumferentially same, and the first end of thermal-collecting tube is positioned at the circle centre position of circumference.
Further, the angle between the rotating shaft of reflecting piece and base is acute angle.
Further, the medial surface of reflecting piece is coated with reflecting coating or is pasted with reflective membrane.
Further, thermal-collecting tube is vacuum tube or metal tube.
In the inventive solutions, multiple reflecting piece all has reflective surface, when sunlight is radiated in reflecting piece, sunshine can reflex on thermal-collecting tube by reflective surface, the thermal energy collecting that solar energy generates gets up by thermal-collecting tube, the medium in heating thermal-collecting tube, makes medium obtain higher temperature.Solar energy heat collector of the present invention is compared with heat collector of the prior art, and overall structure is simple, low production cost.
Accompanying drawing explanation
The Figure of description forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 shows the schematic perspective view of the embodiment according to solar energy heat collector of the present invention;
Fig. 2 shows the schematic top plan view of the solar energy heat collector of Fig. 1; And
Fig. 3 shows the schematic side view of the solar energy heat collector of Fig. 1.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
Fig. 1 shows the schematic perspective view of the embodiment of solar energy heat collector of the present invention, and as can be seen from the figure, the solar energy heat collector of the present embodiment comprises thermal-collecting tube 20 and reflecting piece 30.Wherein, reflecting piece 30 is multiple, multiple reflecting piece 30 is arranged in the circumference of thermal-collecting tube 20, reflecting piece 30 has reflective surface, irradiation or reflection sunshine thereon concentrate on thermal-collecting tube 20 by reflective surface, the thermal energy collecting that solar energy generates gets up by thermal-collecting tube 20, the medium in heating thermal-collecting tube 20, makes medium obtain higher temperature.Solar energy heat collector of the present invention has compared with heat collector that middle high temperature applies with of the prior art, and overall structure is simple, low production cost.
The solar energy heat collector of the present embodiment also includes base 10, and base 10 comprises the foot section 12 in body 11 and supporting body portion, and thermal-collecting tube 20 and reflecting piece 30 are all connected on body 11.Wherein, thermal-collecting tube 20 is arranged perpendicular to body 11, and the first end of thermal-collecting tube 20 is located in body 11, and the second end of thermal-collecting tube 20 deviates from body 11 and forms free end; The first end of multiple reflecting piece 30 is connected on body 11, and multiple reflecting piece 30 is arranged around thermal-collecting tube 20.Preferably, the first end of reflecting piece 30 be evenly distributed on the first end of thermal-collecting tube 20 for the center of circle circumferentially, and point to the first end of thermal-collecting tube 20, the second end of reflecting piece 30 points to the second end of thermal-collecting tube 20.The solar energy heat collector of such setting can, when the sun is in different positions, all have part reflecting piece 30 can receive the irradiation of sunshine, and is transmitted into by sunshine on thermal-collecting tube 20 and heats the medium in thermal-collecting tube 20.As can be seen here, the solar energy heat collector of the present embodiment can realize following the trail of the effect that just can reach omnidistance sunshine without the need to carrying out to day by the simple structure of self, effectively improve the collecting efficiency of solar energy heat collector, make the solar energy heat collector of the present embodiment have higher cost performance.
Reflective surface can be formed by the medial surface of reflecting piece 30, and reflective surface has the bus of arc shaped, and the rotating shaft of reflective surface is the straight line through bus two end points.When sunlight is radiated on reflective surface, the reflection that part sunlight entered reflective surface directly reflexes on thermal-collecting tube 20, another part sunshine finally reflexes on thermal-collecting tube 20 after multiple reflections on one or more reflective surface, heats the medium in thermal-collecting tube 20.For ease of sunlight on reflective surface, between each reflecting piece 30, certain gap should be had.As shown in Figure 2 to Figure 3, reflect in multiple reflective surface for ease of sunlight, certain inclination is carried out to the outside of solar energy heat collector in the top of reflecting piece 30, make to form acute angle between the rotating shaft of reflective surface and body 11 upper surface, preferably, the angle of acute angle is between 15 ° to 45 °.The solar energy heat collector of the present embodiment also comprises fixed mount, and fixed mount comprises support portion and is supported on the annulus on support portion, and fixed mount is fixed each outward-dipping reflecting piece 30 by annulus, and the angle of inclination of reflecting piece 30 is not changed.
For improving the albedo of reflective surface, can on reflective surface, apply reflecting coating or be pasted with reflective membrane, and use vacuum tube or metal tube as thermal-collecting tube 20, with the efficiency of the reflector efficiency or heat exchange that improve links.Each reflecting piece 30 in the present embodiment, can evenly be cut by the spheroid with spherical hollow space or the spheroid with spheroid shape cavity and be formed, namely the spheroid of hollow or the inner surface of elliposoidal are split to form each reflective surface, and namely multiple reflecting piece 30 capable assembling of solar energy heat collector forms spherical or elliposoidal.
Solar energy heat collector of the present invention makes solar energy heat collector have very high collecting efficiency by the Circulated reflection optically focused of reflecting piece, can be widely used in small-sized household system (domestic hot-water, heating etc.), agriculture heating system (hot water heating, air heating), industrial hot water and steam seasoning system etc.And the structure of the reflecting piece of solar energy heat collector is simple, low price, reduces the production cost of solar energy heat collector.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
