Abstract
The utility model relates to photovoltaic and electric industries, in particular to a photovoltaic component with flat miniature diodes; four leading-out bus bars are arranged between two layers of rear panels of the photovoltaic component; the four bus bars are connected through the flat miniature diodes; and heat conduction silica gel layers and EVA (Ethylene-Vinylacetate Copolymer) layers are sequentially laminated between the flat miniature diodes and the external rear panels. The flat miniature diodes are laminated outside the component, and therefore, the size of a terminal box is reduced to the maximum degree, the heat of the diodes is facilitated to be dissipated through the rear panels, the interiors of the components are not affected, and the service life of the photovoltaic component is prolonged; and the photovoltaic component has simple structure, reasonable design and good stability.
Description
Technical field
The utility model relates to photovoltaic and electric utility, especially a kind of photovoltaic module that flat microdiode is laminated to the assembly outside.
Background technology
Solar module is installed in open, sun-drenched area, region usually; The solar module local heating of crested; Can produce hot spot effect; In order to prevent solar cell owing to hot spot effect wrecks, be preferably in bypass diode of parallel connection between the both positive and negative polarity of solar module, the assembly that is masked with the energy of avoiding the illumination assembly to be produced consumes.Yet because the diode volume that tradition is used is bigger, can only in terminal box, install, therefore, the volume of terminal box can't dwindle.
Summary of the invention
The technical problem that the utility model will solve is: for overcoming the problem of above-mentioned existence, provide a kind of thermal diffusivity good, flat microdiode is laminated to the outside photovoltaic module of assembly.
The utility model solves the technical scheme that its technical problem adopted: a kind of photovoltaic module with flat microdiode, have four busbars of drawing between the two-layer backboard of photovoltaic module, and be welded to connect by flat microdiode between four busbars; Between flat microdiode and outer backboard also successively lamination thermal conductive silicon glue-line and EVA layer are arranged, the heat conductive silica gel conductive coefficient is high, the auxiliary heat dissipation ability is strong; Have good compression performance and proof voltage ability; Heat conductive silica gel in use can keep excellent sealing, and air is discharged, and reaches best radiating effect; Also play effects such as damping, insulation simultaneously.The EVA layer also can play weather-proof effect simultaneously, and improves its resistance to impact.
Two lead-in wires of the both positive and negative polarity of photovoltaic module are drawn from the back side of assembly, and flat microdiode positive pole connects battery sheet negative pole, and it is anodal that negative pole connects the battery sheet.
The beneficial effect of the utility model is that the photovoltaic module with flat microdiode of the utility model is laminated to the assembly outside with flat microdiode, has farthest dwindled the size of terminal box; Help diode and see through the backboard heat radiation; Component internal is had no influence, effectively prolonged the useful life of photovoltaic module, simple in structure; Reasonable in design, good stability.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structure cutaway view of the utility model.
Fig. 2 is the structural representation of the utility model.
1. flat microdiodes among the figure, 2. thermal conductive silicon glue-line, 3.EVA layer, 4. backboard, 5. busbar.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The photovoltaic module with flat microdiode shown in Figure 2 like Fig. 1 has four busbars of drawing between the two-layer backboard of photovoltaic module, be welded to connect by flat microdiode between four busbars.
As shown in Figure 1, on flat microdiode, spread heat conductive silica gel layer 2, subsequently at last laying EVA layer 3; On EVA layer 3, repave one deck backboard 4 then, flat microdiode 1 is clipped in the middle by two-layer backboard 4, in laminating machine through vacuumizing; Heat, pressurization, EVA layer 3 melts; With each layer sticking together tightly, realize the effect that battery sheet and air completely cut off.The both positive and negative polarity of photovoltaic module is drawn from the assembly back side through two lead-in wires.Flat microdiode 1 positive pole connects battery sheet negative pole, and it is anodal that negative pole connects the battery sheet.Flat microdiode 1 is connected solar battery sheet series two ends in parallel.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
