Regenerative resource.Solar energy is of increased attention as the renewable new energy of a kind of cleaning, green, its application
Widely.
To make full use of solar energy resources, electric power energy is converted solar energy into, people have been manufactured based on silicon materials
Solar cell, monolithic solar cell because its electrical property and size limitation far from meet electric power energy conversion need
Will, therefore, a number of solar cell is connected in series, and encapsulation by safety glass, EVA, backboard is constituted too
It is positive can component, nowadays solar components have become field of solar thermal power generation the most extensively and ripe product, it is small to solar energy
Street lamp, the big large-sized photovoltaic power station to MW class, solar components have played huge effect.
The technique of traditional solar components is first to weld solar battery sheet, then with safety glass, EVA and backboard
Stacking is integrated, and it is laminated by laminating machine then, is fabricated to laminate, and then laminate is encapsulated with aluminium frame again
Get up, terminal box is finally installed, by the output end thereto of component, this completes the making of solar components.
Wherein, safety glass not only acts as the protective effect to component, and can make more sunshine because its light transmittance is higher
Incide on the solar battery sheet of component internal；EVA is combined together with making component each several part material tight, serves sealing
With the effect of protection；Aluminium frame integrally serves the effect of support protection and sealing to solar components；Terminal box is used as the sun
The output end of energy component, can facilitate the electric power output for producing component to external circuit, while also being risen to solar battery sheet
Electic protection effect is arrived.
Although the structure and the material comparative maturity of each several part of above tradition solar components, but it is in need further
Perfect place.For example, the manufacturing process of solar cell module is relatively complicated, it is related to many different materials, each material
More independent between material, integrated level is not high.In addition, traditional terminal box heat-sinking capability is poor so that the diode in terminal box
With junction temperature higher, the failure of diode is easily caused for a long time；The solar battery sheet at the other terminal box back side can also be received
To influence, due to the inconsistent mismatch that result between them of solar battery sheet temperature, the power output of component is reduced.
The content of the invention
For problem above, it is an object of the invention to provide the solar components that a kind of terminal box is integrated, by terminal box with
Frame becomes one, and not only reduces the manufacturing process of solar components, saves the production time, reduces production cost.Separately
On the one hand, because terminal box is placed in inside frame, the heat dissipation problem of terminal box is solved, improves reliability and the output of component
Power.
The present invention realizes that the technical scheme of above-mentioned purpose is as follows：
A kind of integrated solar components of terminal box, including laminate, terminal box and frame, it is characterised in that：Described frame
Including the first long margin frame, the second long margin frame, the first short frame and the second short frame, frame is equipped with the groove for installing laminate,
Silica gel sealing is used between frame and laminate；Described terminal box is integrated in the separate chamber inside the first short frame, first
Short frame has and the first long margin frame, the second long margin frame and the different section of the second short frame.
Described terminal box includes box body, lid and lead-out terminal, and convergent belt binding post, bypass two are provided with box body
Pole pipe, binding post, convergent belt binding post are connected in parallel with bypass diode, and binding post is connected with lead-out terminal.
Described laminate include set from top to bottom safety glass, upper EVA layer, solar battery sheet, lower EVA layer and
Backboard, the convergent belt that solar battery sheet is connected in series is drawn from laminate side.
Described separate chamber is provided with left through hole and right through hole, and terminal box lead-out terminal is drawn from left through hole, convergent belt from
Right through hole introduces junction box, and is connected with convergent belt binding post.
Silicone insulation and sealing are used between described terminal box body and the first short frame, on lid and the first short frame
Surface flushes.
Described frame is aluminum alloy material, and frame side is provided with screw, is attached and is consolidated using screw between frame
It is fixed.
Be integrated in the terminal box of component within frame by the present invention, reduces the manufacturing process of component, improves component
Production efficiency.In addition, the good thermal conductivity of frame greatly improves the heat-sinking capability of terminal box, the temperature of junction box is reduced
Degree, improves the reliability of terminal box and component.Because terminal box is arranged on inside frame, as terminal box in general components structure
This problem of the larger negative effect that heating is caused to solar battery sheet is completely absent in the present invention, so that group
The operating temperature that solar battery sheet in part can be consistent, it is therefore prevented that solar battery sheet temperature differs in general components
The mismatch loss for producing is caused, so as to improve the overall output power of component.
