Description

Flat-plate solar power generating and heating system
Technical field
The present invention relates to a kind of plate type solar system, particularly a kind of solar power generating and heating system that comprises solar cell and solar collector simultaneously.
Background technology
Solar cell and solar water heater two big purposes have mainly been developed in the utilization of solar energy at present, use as important green energy resource in the sustainable development and have obtained general approval.The solar cell utilization be that as the photovoltaic effect of solar cell material luminous energy to be converted into electric energy prepared, the heat that solar water heater then utilizes solar energy to produce adds liquid such as hot water.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of flat-plate solar power generating and heating system, and it can generate electricity also can heat production.
For solving the problems of the technologies described above, flat-plate solar power generating and heating system of the present invention system, this solar energy system is integrated with solar cell and solar collector, the plate body of this solar energy system is formed by lower plywood and the upper panel driving fit that lower floor is tray shape, upper panel is the substrate of solar cell, each functional layer of solar cell is positioned at the upper surface of upper panel, is the heat-conducting liquid medium channel between lower plywood and the upper panel.
Plate type solar of the present invention system, solar cell and solar collector are integrated by plate body setting dull and stereotyped at the middle and upper levels and lower plywood, because of the electricity conversion of solar cell is about 5-15%, the conversion of solar energy of remaining about 85-95% is a heat energy, this partial heat energy can pass to the liquid medium of being close to by upper panel, if this medium is a water, just can directly use for the user; If medium is the liquid of non-water, then can thermal energy transfer be fed water, and then use for the user by the mode of heat exchange.Therefore flat-plate solar power generating and heating system of the present invention has made full use of the conversion of solar photoelectric and photo-thermal.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the decomposing schematic representation of flat-plate solar power generating and heating system of the present invention;
Fig. 2 is the schematic partial cross-sectional view of the plate body of flat-plate solar power generating and heating system of the present invention;
Fig. 3 is the example sectional view of flat-plate solar power generating and heating system of the present invention;
Fig. 4 is the decomposing schematic representation of another flat-plate solar power generating and heating system example of the present invention.
Embodiment
Flat-plate solar power generating and heating system of the present invention, be integrated with solar cell and solar collector, this system comprises that the lower plywood 11 and upper panel 12 driving fits that are tray shape by lower floor form plate body (seeing Fig. 1 and Fig. 2), upper panel 12 is the substrate of solar cell, each functional layer 19 (also be solar module, comprise the PN junction layer that constitutes the solar cell body etc.) that constitutes solar cell is positioned at the upper surface of upper panel 12 upper surface of upper panel (or be encapsulated in).Be liquid medium passage (this liquid medium can be water, also can be other heat absorption liquid) between lower plywood 11 and the upper panel 12, liquid medium 18 is applied in the passage.
Employed solar module all can adopt existing known structure in the flat-plate solar power generating and heating system of the present invention, as be encapsulated in monocrystalline silicon and polysilicon type solar cell on the substrate, be deposited on the amorphous silicon type solar cell on the substrate, and the multi-element compounds type solar cell of evaporation on substrate etc.Upper panel is that the substrate of solar cell can be selected glass, metal (as stainless steel or copper etc.), pottery or plastics for use.When upper panel was metal, its lower surface should be coated with insulating barrier, further, also can increase fish tail and waterproof layer as required to guarantee its insulation property and Corrosion Protection outside insulating barrier.
Lower plywood 11 can be plastics or metal, can be upper header 13 and lower collector pipe 14 is simultaneously integrated by integrated mode, and the undesirable problem of driving fit in having avoided being installed separately has reduced production process, has improved production efficiency, has reduced failure rate.As select plastics then to be preferably the plastics of dark color (for example black), because of its heat insulating ability better.In the practical application, a plurality of parallel vertical parting beads 15 also can be set in the lower plywood, the situation lower support upper panel that is used for large-area flat-plate, form the liquid medium passage, simultaneously can control gap between lower plywood and the upper panel by the height of vertical parting bead, reach the maximum optimization heat efficiency, available water also can be selected the liquid that other heat absorptivity is good or apparent freezing point is lower than water (as glycols etc.) for use as heat absorption liquid in the liquid medium passage.Parallel vertical parting bead 15 also can be made as a plurality of protruding 16 (block-shaped protrusion or some projection), can control gap (see figure 4) between lower plywood and the upper panel by the height of block-shaped protrusion when supporting upper panel.
The fish tail and waterproof layer of upper panel inner surface is preferably black, can also absorb heat to greatest extent when it can protect insulating barrier, and prevents that the heat that has absorbed outwards scatters and disappears, thereby reduces thermal loss.That the driving fit of upper panel and lower plywood can be adopted is bonding, welding or adopt securing member to be connected, or the combination in any of above-mentioned several modes.
The present invention gap between flat board and the lower plywood at the middle and upper levels will optimize, and can decide according to concrete application, and as guaranteeing being heated amount of liquid and having more significantly than existing design and improve of same time, this requires the gap to want big; As guaranteeing firing rate faster, this requires the crack little.Because under the prerequisite that guarantees less gap, the amount of being heated of same time has significantly improved than existing design, supposes that the heat efficiency of the present invention is not less than existing design, then can draw the conclusion that the daily output can be improved.
Because of solar cell all is encapsulation or is deposited on the substrate on plane, just in time be suitable as the upper cover plate of this flat plate collector.
In example of the present invention, also can further be provided with transparent outer cover plate 23 (see figure 3)s in addition, also have suitable air layer 22 between outer cover plate and solar cell.And heat-insulation layer 20 also can be set under the lower plywood, heat-insulation layer is backboard 21 down.Adopt flat-plate solar power generating and heating system of the present invention, sunlight 1 saw through outmost transparent outer cover plate 23 and impinged upon on the solar cell on the upper panel before this, the part phototransformation is collected and output by the circuit that matches for the electricity back, the part that is not converted to electricity will be converted into heat energy, give liquid medium by the upper panel substrate transfer, realized the conversion of photovoltaic and photo-thermal simultaneously.So flat-plate solar power generating and heating system of the present invention, structure by plate body is provided with solar cell and solar collector is integrated, make a cover system can realize two kinds of functions, made full use of solar energy, also can save the floor space of this system in the cost-effective while.
