Description
Technical field
The present invention relates to a kind of flat-plate solar collector with optically focused energy supply.
Background technology
At present, flat-plate solar heat collector is generally made up of a few parts such as transparent cover plate, metal absorber plate, thermal insulation layer and shells, when flat-plate solar heat collector works, solar radiation is through after transparent cover plate, be incident upon on absorber plate, absorbed by absorber plate and change into heat energy, then pass to the heat-transfer working medium in absorber plate, the temperature of heat-transfer working medium is raised, and the useful energy as heat collector exports; Meanwhile, the absorber plate after temperature raises inevitably will by conducting, the mode of convection current and radiation dispels the heat to surrounding, become the thermal loss of heat collector, owing to not having vacuum, therefore its heat loss coefficient is larger than vacuum tube collector.
The present invention is exactly the problem that heat waste is comparatively large and heat transfer efficiency is low in order to solve current flat-plate solar heat collector.
Summary of the invention
The present invention, in order to overcome the deficiency in prior art, provides a kind of raising heat transfer efficiency, reduces the light-focusing type flat-plate solar collector of heat waste.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of light-focusing type flat-plate solar collector, comprise flat plate collector, spotlight camber and support, described flat plate collector has front and back, just arranging facing to sunshine of described flat plate collector, described spotlight camber is arranged at the back side or the both sides of flat plate collector, described spotlight camber assemble and reflected sunlight to the back side of flat plate collector, the front and back of described flat plate collector is equipped with transparent cover plate, be provided with dull and stereotyped absorber in described flat plate collector, described flat plate collector and spotlight camber are all mounted to support.
More specifically, described spotlight camber is metal material or glass reflector or macromolecule reflecting material.
More specifically, described spotlight camber is sphere or parabola.
More specifically, described flat plate collector is arranged at the non-focus position of spotlight camber.
More specifically, described support is fixed support or runing rest.
More specifically, described runing rest can from the direction of motion tracking sun operation.
More specifically, the described flat plate collector back side is provided with selective heat absorbing coating.
More specifically, described dull and stereotyped absorber is made up of endothermic tube and the outer fin of pipe.
Beneficial effect of the present invention is, the present invention installs spotlight camber additional at the back side of flat plate collector, and form the heat dump of low-concentration ratio, greatly reduce heat waste, this flat plate collector can reach higher efficiency.
Accompanying drawing explanation
Fig. 1 is one of structural representation of the present invention.
Fig. 2 is the structural representation of flat plate collector of the present invention.
Fig. 3 is structural representation two of the present invention.
Detailed description of the invention
Present pre-ferred embodiments is provided, to describe technical scheme of the present invention in detail below in conjunction with accompanying drawing.
Embodiment is by flat plate collector 1, spotlight camber 3 and support (not shown) are formed, described flat plate collector 1 has front 5 and the back side 6, the front 5 of described flat plate collector 1 is arranged towards sunshine, described spotlight camber 3 is arranged at the back side or the both sides of flat plate collector 1, described spotlight camber 3 assemble and reflected sunlight to the back side 6 of flat plate collector 1, front 5 and the back side 6 of described flat plate collector 1 are equipped with transparent cover plate 4, dull and stereotyped absorber 7 is provided with in described flat plate collector 1, described dull and stereotyped absorber 7 is made up of endothermic tube 8 and the outer fin 9 of pipe, described flat plate collector 1 and spotlight camber 3 are all mounted to support.
Solar radiation 2 arrives and is positioned at the back side of flat plate collector 1 or the spotlight camber 3 of both sides, and it is inner that solar radiation 2 enters flat plate collector 1 by the back side of flat plate collector 1 after being reflected by spotlight camber 3, arrives the back side 6 of dull and stereotyped absorber 7.Under solar irradiation, the Absorbable rod solar radiation simultaneously of the front 5 of flat plate collector 1 and the back side 6.
Flat plate collector 1 and spotlight camber 3 are all arranged on support, this support is possess the runing rest following the tracks of sun operation function or the fixed support not possessing tracking sun operation function, spotlight camber 3 is placed on the back side or the both sides of flat plate collector 1, spotlight camber 3 spherically or parabolic shape, can be glass reflector, also can be made by metal, macromolecule reflecting material.Flat plate collector 1 is not generally positioned at the focal position of spotlight camber 3, avoids that flat plate collector 1 is overheated to be burnt.Flat plate collector 1 all adopts euphotic cover plate due to two faces, makes solar radiation 2 can arrive dull and stereotyped absorber 7 by two faces of flat plate collector 1 simultaneously.Solar radiation 2 arrives the outer fin 9 of pipe, passes to the fluid media (medium) of flowing in endothermic tube 8 after managing the heat absorption of outer fin 9.
Main feature of the present invention is: solar radiation 2 is reflected by spotlight camber 3, focus on the back side 6 of dull and stereotyped absorber 7, the front 5 of dull and stereotyped absorber 7 is also in absorption solar radiation simultaneously, if the aperture area of spotlight camber 3 reaches 2 times of dull and stereotyped absorber 7, now sun focusing ratio reaches about 2; If the aperture area of spotlight camber 3 reaches 4 times of dull and stereotyped absorber 7, now sun focusing ratio about reaches 5.Now flat plate collector 1 will reach higher efficiency.
Flat plate collector 1 of the present invention is with conventional flat plate collector difference, the bottom of dull and stereotyped absorber 7 does not have insulation material, lower cover also changes transparent cover plate 4 into, and as glass material, the solar radiation 2 that spotlight camber 3 is reflected can reach the back of dull and stereotyped absorber 7.
The outer fin 9 of pipe of dull and stereotyped absorber 7 is fin-tube type structure, and the solar radiation 2 of reflection arrives the outer fin 9 of pipe of dull and stereotyped absorber 7, passes to the fluid media (medium) of flowing in endothermic tube 8 after managing the heat absorption of outer fin 9.
Flat plate collector 1 and spotlight camber 3 are all placed on support, and this support can be followed the tracks of the sun and run.
The shape of spotlight camber 3 can be parabola or sphere or plane, and flat plate collector 1 is not generally positioned at the focal position of spotlight camber 3, in order to avoid the heat transfer problem under high fluence density causes dull and stereotyped absorber 7 to burn.
Outstanding advantages of the present invention is: general flat-plate solar collector efficiency comparison when hot operation is low, can reduce heat waste after have employed light condensing technology, solves flat plate collector hot operation efficiency.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection scope of the present invention.
