Abstract
The invention relates to a solar collector which comprises a carriage; the surface of the carriage is provided with a solar reflective film, and the solar collector is also provided with a plurality of vent holes; the vent holes pass through the solar reflective film; consequently, no any glass reflector or thin steel sheet with a metal reflective layer is needed so as to reduce the manufacturing and maintenance cost; and simultaneously, the vent holes can effectively reduce the air resistance.
Description
[technical field]
The present invention relates to a kind of solar collector, belong to field of solar energy utilization.
[background technology]
Existing solar collecting device mainly is to utilize glass reflector is made as different angles, thereby the sunlight that will be radiated on this speculum reflexes on the destination apparatus again, this destination apparatus can be solar photovoltaic cell panel or solar energy heat collector, so to realize walking around of photoelectricity or photo-thermal.The weak point that this kind structure exists is that the glass reflector cost is higher, and is difficult for changing after damage, thereby is unfavorable for reducing the manufacturing and the maintenance cost of whole system.Though also having to adopt, industry is coated with the sheet metal of metallic reflector as speculum, but the weak point of this kind structure is to be easy to be worn or corrode when metallic reflector, and be difficult for changing, industry is fabricated to an integral body to reduce cost with this thin type steel plate mostly simultaneously, yet because this solar collecting device all is placed in the outdoor environment, this kind structure can cause the windage of this solar collecting device bigger, so need to strengthen the mechanical support structure of this solar collecting device, and this can increase the manufacturing cost of system undoubtedly.
[summary of the invention]
The object of the invention is to provide a kind of solar collector, in order to overcome the defective that cost is higher and windage is bigger of existing solar collector.
For achieving the above object, implement solar collector of the present invention and comprise a bracing frame, and this bracing frame surface is provided with sun reflectance coating, and this solar collector also is provided with a plurality of ventilation holes, these ventilation holes run through this supporting bracket and reflectance coating.
According to above-mentioned principal character, group is provided with a fixture in this ventilation hole, and this fixture middle part is provided with a through hole, and this fixture one end margin is provided with the fin that extends to the periphery, and this fin is pressed in the reflectance coating surface at ventilation hole edge.
According to above-mentioned principal character, this fixture other end is provided with bullet spare bayonet unit, with the support plate edge buckle so that this fixture is fixed on the supporting bracket.
According to above-mentioned principal character, this bracing frame is staggered to be provided with a plurality of separation ribs, thereby makes bracing frame be lattice-shaped, and the intersection of separation rib is provided with fixing hole, the other end of this fixture is housed in this fixing hole, and the Elastic buckle device of this fixture and this fixing hole edge fastening.
Compared with prior art, the present invention is by being arranged at a sun reflectance coating on the bracing frame surface to form solar mirror, and a plurality of ventilation holes that run through this sun reflectance coating are set, the thin type steel plate that does not need to use glass reflector and be provided with metallic reflector like this, make and maintenance cost thereby be beneficial to reduce, can reduce windage effectively by being provided with of ventilation hole simultaneously.
[description of drawings]
Fig. 1 is for implementing the perspective view of solar collector of the present invention.
Fig. 2 is the perspective exploded view of solar collector shown in Figure 1.
[embodiment]
See also Fig. 1 and shown in Figure 2, implement solar collector 1 of the present invention and mainly comprise a bracing frame 10, these bracing frame 10 surfaces are provided with sun reflectance coating 11, and this solar collector 1 also is provided with a plurality of ventilation holes 110, and these ventilation holes 110 run through this sun reflectance coating 11.In the specific implementation, this solar collector 1 also can be provided with sun tracker (not shown), thereby make solar collector 1 follow the tracks of between solar day or in the period of motion, thereby more sunlight is reflexed on the destination apparatus (not shown) corresponding with this solar collector 1.In addition, this sun reflectance coating 11 can be ESR (the Enhanced Specular Reflector) reflector plate that Minnesota Mining and Manufacturing Company produces, and the reflectivity of this reflector plate can surpass 98.5%.Perhaps this sun reflectance coating also can be organic reflectance coating that the surface is coated with aluminium lamination or silver layer, and this reflectance coating surface is typically provided with antireflection layer and protective layer, thereby improves the sunlight reflectivity and can prevent coat of metal oxidation or corrosion.
In addition, for being blown up with bracing frame 10, sun reflectance coating 11 edge curl that prevent ventilation hole 110 edges break away from, can organize in this ventilation hole 110 and establish a fixture 12, these fixture 12 middle parts are provided with a through hole 120 to ventilate, and these fixture 12 1 end margins are provided with the fin 121 that extends to the periphery, this fin 121 is pressed in sun reflectance coating 11 surfaces at ventilation hole 110 edges, and the other end of this fixture 12 can be provided with bullet spare bayonet unit (not shown), with bracing frame 10 edge buckles so that this fixture 12 is fixed on the bracing frame 10.Preferably, this bracing frame 10 interlocks and is provided with a plurality of separation ribs 100, thereby make bracing frame 10 be lattice-shaped, and the intersection of separation rib 100 is provided with fixing hole 101, the other end of this fixture 12 is housed in this fixing hole 101, and the Elastic buckle device of this fixture 12 and this fixing hole 101 edges fastening.
When implementing, can earlier sun reflectance coating 11 integral body be attached on the bracing frame 10, sun reflectance coating 11 with ventilation hole 110 place's correspondences crops or offers the cross opening afterwards, again fixture 12 is buckled in the ventilation hole 110 afterwards, make the fin 121 of fixture 12 be pressed on sun reflectance coating 11 surfaces, so can prevent sun reflectance coating 11 edge curl and be blown up and bracing frame 10 breaks away from.If sun reflectance coating 11 is impaired when needing to change, then only need fixture 12 is taken out, old solar energy reflection film is taken down, newer sun reflectance coating is attached on the bracing frame 10, and fixture is located in the ventilation hole 110 for 12 groups gets final product.
Compared with prior art, the present invention forms solar mirror by a sun reflectance coating 11 is affixed on the bracing frame 10, and be provided with a plurality of air vents 110 that run through this sun reflectance coating, the thin type steel plate that does not need glass reflector and be provided with metallic reflector like this, make and maintenance cost thereby be beneficial to reduce, can effectively reduce windage by arranging of air vent 110 simultaneously, thereby not need complicated mechanical support structure, also be beneficial to the reduction manufacturing cost.
