Description
Technical field
The present invention relates to the photovoltaic field, particularly a kind of cooling device of solar cell system.
Background technology
Solar power system is normally formed by the solar cell module array that solar module forms, solar module comprises lamination part of solar cell, lamination part of solar cell is comprised of header board, EVA, solar battery sheet, EVA and backboard five-layer structure from top to bottom successively, and it is entrenched in solar module and installs in the section bar.Existing solar module is installed section bar and is adopted aluminium alloy extrusions, as shown in Figure 1, comprises laminate installation notch 1; Inwall 3 is approximately perpendicular to described laminate notch 1 is installed; Support edge 4 is approximately perpendicular to described inwall 3, and extends to described laminate the identical direction of notch 1 being installed from described inwall 3; Outer wall 7 is approximately perpendicular to described laminate notch 1 is installed, and an end of described outer wall 7 is coupled to described laminate notch 1 is installed, and the other end is coupled to described support edge 4; One end of described inwall 3 is coupled to described laminate notch 1 is installed, and the other end is coupled to described support edge 4.Assembly requires to reach 25 years useful life, and existing solar module reaches at this following hidden danger in use procedure in 25 years:
(1) the assembly battery do not mate, battery crackle, inner Joint failure, local by shading or make dirty, all can cause assembly local overheating phenomenon, i.e. the hot spot effect; Hot spot effect may cause burning of components welding fusing, encapsulation degeneration even encapsulating material;
(2) solar battery sheet is played protection and the backboard of supporting role, be generally polymerizable material, it easily is scratched in installation and use procedure, and the backboard scuffing can cause the staff to get an electric shock;
(3) the anti-UV intensity of backboard is mainly investigated backboard and is stood the ability that wavelength is the UV-irradiation of 300-380nm, insulating material in the middle of present nearly all backboard all is PET, some backboard outermost layer weathering layer also is PET, PET is easy xanthochromia under the UV-irradiation of 300-380nm, so xanthochromia can occur in the part backboard under the irradiation of ultraviolet light, cause the backboard part destroyed, the overall performance of backboard descends, the reflectivity of backboard reduces simultaneously, affect the integral body output of assembly, affect simultaneously the useful life of assembly;
(4) traditional components is in application process, the sunlight that cell piece itself absorbs is understood some and is transformed into heat energy, causes the component internal temperature to raise, and the ultraviolet absorber in the EVA converts the ultraviolet light that absorbs to a part of heat energy, be dispersed into component internal, thereby cause the assembly heating.And the power stage of assembly and himself temperature are closely related: the actual power of the assembly take maximum power as 240W in system is output as example, 1 ℃ of the every rising of assembly self temperature, the power output of the assembly approximately 1W that will descend accordingly;
(5) rate of ageing of the backboard of assembly and EVA all has direct relation with assembly temperature and light radiation.The ageing-resistant intensity of backboard mainly tests the ability to bear of backboard under long-time ultra-violet radiation, high hot state, and the fluorine material weatherability of the fluorine-containing backboard that uses at present own is relatively strong, but not the weatherability of fluorine-containing backboard relatively a little less than.In general, under for a long time ultra-violet radiation and Gao Re state, backboard can scratch, the bad phenomenon of xanthochromia, cracking and embrittlement.A series of Norrish chemical reaction degradation with aging under the effect of light and heat, can occur in component internal in EVA, and these reactions all are risings along with temperature, and reaction rate is larger.
In order to address the above problem, some adopts the structure of water pipe cooling to form the solar cell cooling package, for example in Chinese patent 201010193965 " cooling device of solar photovoltaic generation system " and the Chinese patent 201010534553 " cooling package of solar-energy photo-voltaic cell ", be provided with cooling water tank, described cooling water tank comprises metallic plate and is used for the water pipe of circulating cooling liquid, described metallic plate and backboard are fitted by heat-conducting glue, and water pipe is fitted in the another side of metallic plate.This structure part that still comes with some shortcomings:
(1) thermally conductive pathways is long, and assembly need to pass through heat-conducting glue, metallic plate, (coolant pipe) to cooling fluid, and wherein the conductive coefficient of heat-conducting glue and coolant pipe is lower, affects the cooling effect of assembly;
(2) the assembly lowering temperature uniform is poor, use the water pipe of coiling to cool off, the position rate of temperature fall that is fitted with water pipe is relatively very fast, cooling effect is relatively better, the large-area position rate of temperature fall that does not have water pipe to fit is then very slow, initial stage agio pipe and not agio pipe position temperature can differ more than 10 ℃, equilibration time sometimes needs to be thirty minutes long even is more of a specified duration;
(3) cooling device is combined with assembly and is difficult for, need weather-proof power strong, the heat-conducting glue that cohesive force is strong, subassembly product requires to use out of doors to reach 25 years, need to stand the pressure that strong wind brings, and heavy snow covers the pressure that produces, the component layer casting die has certain deformation in pressurized process, especially at the weather of strong wind, the component layer casting die will be in the process of dynamic change always, and traditional cooling device is the material of rigidity, only carries out adhesion by heat-conducting glue and assembly, so heat-conducting glue is had high requirement; Heat-conducting glue also will overcome the weight of cooling device integral body in addition, comprising: the weight of metallic plate, water pipe and cooling fluid; Moreover assembly useful life require to reach 25 years, so the weatherability of heat-conducting glue is also had very high requirement;
(4) cooling device and assembly are difficult for effective separation, adopt heat-conducting glue that metallic plate and backboard are fitted, and cooling device lost efficacy when needing replacing or dismounting from now on, easily caused the backboard damage, and the electrical apparatus insulation performance failure of assembly causes that the operator gets an electric shock;
(5) adopt heat-conducting glue that metallic plate and backboard are fitted, can cause can't dismantling after the moulding, maintenance is inconvenient;
(6) use material more, and the life requirements of using 25 years in order to meet assembly, also very high to the requirement of material property, the screening of initial stage material, the production cost of cooling package is higher after making.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome in the prior art, bad and the deficiency that causes many adverse consequencess and backboard easily to be scratched of solar module radiating effect, overcome existing cooling device inhomogeneous cooling even, the long cooling effect of thermally conductive pathways is poor, cooling device be combined with assembly fastness poor wait not enough, the invention provides a kind of cooling device of solar cell system, greatly improve the outdoor actual power generation of solar module, significantly alleviate even the elimination hot spot effect, greatly improve the scratch resistance of solar module, uvioresistant performance, and prolong solar cell module back veneer and EVA useful life.
