Description
Technical field
The present invention relates to light volt field, in particular to a kind of solar cell cooling module and frame thereof.
Background technology
Lamination part of solar cell under be made up of header board, EVA, solar battery sheet, EVA and backboard five-layer structure successively, it is entrenched in solar module and installs in section bar. Existing solar module is installed section bar and is adopted aluminium alloy extrusions, as shown in Figure 1, comprises laminate and installs notch 1; Inwall 3, is approximately perpendicular to described laminate and installs notch 1; Support edge 4, is approximately perpendicular to described inwall 3, and extends from described inwall 3 to installing the identical direction of notch 1 with described laminate; Outer wall 7, is approximately perpendicular to described laminate and installs notch 1, and the coupled one end of described outer wall 7 installs notch 1 to described laminate, and the other end is coupled to described support edge 4; The coupled one end of described inwall 3 installs notch 1 to described laminate, and the other end is coupled to described support edge 4. Assembly requires to reach 25 years work-ing life, and existing solar module reaches in use procedure in 25 years at this following hidden danger:
(1) assembly battery do not mate, battery crackle, inner Joint failure, local be blocked or make dirty, all can cause assembly local superheating phenomenon, i.e. hot spot effect; Hot spot effect may cause components welding fusing, encapsulation to be degenerated the burning of even packaged material;
(2) solar battery sheet playing protection and the backboard of supporting role, be generally polymerizable material, it is being installed and is easily being scratched in use procedure, and backboard is drawn wound staff can be caused to get an electric shock;
(3) paper examines of the resistance to UV intensity backboard of backboard stands the ability that wavelength is the UV-irradiation of 300-380nm, insulating material in the middle of current nearly all backboard is all PET, some backboard outermost layer weathering layer is also PET, PET is easily yellow under the UV-irradiation of 300-380nm to be become, so yellow change can be there is under the irradiation of UV-light in part backboard, backboard integral part is caused to be destroyed, the overall performance decline of backboard, the reflectance reduction of backboard simultaneously, affect the overall output of assembly, affect the work-ing life of assembly simultaneously;
(4) traditional components is in application process, the sunlight that cell piece itself absorbs is understood some and is transformed into heat energy, causes component internal temperature to raise, and the UV-light of absorption is converted to part heat energy by the uv-absorbing agent in EVA, it is dispersed into component internal, thus causes assembly to generate heat. And the power stage of assembly and himself temperature are closely related: be that the assembly real power in systems in which of 240W exports taking peak power be example, assembly own temperature often rises 1 DEG C, and the output rating of assembly will decline about 1W accordingly;
(5) backboard of assembly and the rate of ageing of EVA all have direct relation with assembly temperature and optical radiation. The ageing-resistant intensity of backboard mainly tests the ability to bear of backboard under long-time uv-radiation, high Warm status, and the fluorine material weathering resistance of the fluorine-containing backboard used at present own is relatively strong, but not the weathering resistance of fluorine-containing backboard is relatively weak. In general, under long-time uv-radiation and high Warm status, can there is to draw the bad phenomenon of wound, yellow change, cracking and embrittlement in backboard. In component internal, under the effect of light and heat, can there is a series of Norrish chemical reaction degradation with agings in EVA, and these reactions are all the risings along with temperature, and speed of reaction is more big.
In order to solve the problem, some adopts the structure of water pipe cooling to form solar cell cooling module, such as, in Chinese patent 201010193965 " refrigerating unit of solar photovoltaic generation system " and Chinese patent 201010534553 " cooling module of solar-energy photo-voltaic cell ", it is provided with cooling water tank, described cooling water tank comprises metal sheet and the water pipe for circulating cooling liquid, described metal sheet and backboard are fitted by heat-conducting glue, and water pipe is fitted in the another side of metal sheet. This kind of structure still comes with some shortcomings part:
(1) thermally conductive pathways is long, and assembly needs through heat-conducting glue, metal sheet, (cooling fluid pipe) to cooling fluid, and wherein the thermal conductivity of heat-conducting glue and cooling fluid pipe is lower, affects the cooling performance of assembly;
(2) assembly lowering temperature uniform is poor, the water pipe of coiling is used to cool, the position rate of temperature fall being fitted with water pipe is relatively very fast, cooling performance is relatively better, big area do not have position rate of temperature fall that water pipe fits then slowly, initial stage agio pipe and non-agio pipe position temperature can differ more than 10 DEG C, and it is even more of a specified duration that starting time needs to reach 30 minutes sometimes;
(3) refrigerating unit is combined not easily with assembly, need weather-proof power strong, the heat-conducting glue that cohesive force is strong, subassembly product requires to reach 25 years in open air use, need to stand the pressure that strong wind brings, and heavy snow covers the pressure produced, component layer casting die has certain deformation in pressurized process, especially at the weather of strong wind, component layer casting die will be in the process of dynamic change always, and traditional refrigerating unit is the material of rigidity, carry out adhesion only by heat-conducting glue and assembly, so heat-conducting glue there being extremely high requirement; Heat-conducting glue also to be overcome the weight of refrigerating unit entirety in addition, comprising: the weight of metal sheet, water pipe and cooling fluid; Moreover assembly requires to reach 25 years work-ing life, so the weathering resistance of heat-conducting glue is also had very high requirement;
(4) refrigerating unit is not easily effectively separated with assembly, adopts heat-conducting glue to make metal sheet and backboard laminating, when refrigerating unit lost efficacy and needs replacing or dismounting from now on, it is easy to causing backboard to damage, the electrical apparatus insulation performance failure of assembly, causes operator to get an electric shock;
(5) using material more, and use the life-span requirement of 25 years in order to meet assembly, the requirement of material property is also very high, and the screening of initial stage material, after making, the production cost of cooling module is higher.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome in prior art, solar module radiating effect is not good and causes the deficiency that many adverse consequencess and backboard are easily scratched, overcome existing refrigerating unit inhomogeneous cooling even, the long cooling performance of thermally conductive pathways is poor, refrigerating unit and assembly are in conjunction with deficiencies such as stability differences, the present invention provides a kind of solar cell cooling module and frame thereof, the direct contact assembly backboard of cooling fluid, reach the fastest speed of cooling and best cooling performance, greatly improve the outdoor actual power generation of assembly, significantly alleviate and even eliminate hot spot effect, greatly improve the anti-zoned wound of assembly, uvioresistant performance, extend backboard and EVA work-ing life.
