Description
Technical field
The present invention relates to solar-photovoltaic technology field, particularly a kind of photovoltaic component terminal box with high efficient heat dissipation performance.
Background technology
Increasingly serious along with Global climate change and problem of environmental pollution, green regenerative energy sources industry last decade is developed rapidly.Solar energy is a kind of renewable resource, and the solar cell technology utilizing photovoltaic effect to carry out generating electricity enjoys common people to pay close attention to.Solar cell is by the material that can produce photovoltaic effect, as the materials such as silicon, GaAs, indium selenium copper are made, light energy conversion can be become electric energy.At present, the photovoltaic module combined by multi-disc solar cell is widely used for building various photovoltaic generating system, or for building up energy saving and environment friendly building as constructure screen wall.
In actual use, need the electric energy using photovoltaic component terminal box to be produced by photovoltaic module to draw to be connected with outside load.Therefore, photovoltaic component terminal box is the critical component that photovoltaic module builds various electricity generation system.In terminal box, generally will use diode, first can play bypass effect, and protection solar components normal power generation, can not affect whole electricity generation system because a certain piece of cell panel damages; Second can play the effect making electric current following current, can not puncture cell panel because of the adverse current of storage battery.Because diode is a heater members, and for security consideration, diode is inner is all generally sealing, therefore, in order to ensure the useful life of terminal box, has just become an important topic how to the diode radiating of junction box.In terminal box before, generally all adopt axial diode, cost compare is cheap, but radiating effect is bad and allow the electric current that passes through general also smaller, generally all adopts chip diode now, good heat dissipation and larger current can be allowed to pass through.For the heat radiation of junction box, not only want rapid heat dissipation, junction box heat radiation everywhere also will be allowed more average, the high temperature of local can not be occurred, otherwise finally also can cause whole terminal box generation thermal deformation, affect its useful life.
Summary of the invention
The object of the invention is, based on the use of existing chip diode, a kind of terminal structure design of the junction box more optimized and the arrangement of diode are provided, help diode to dispel the heat faster, make to have in terminal box heat dispersion more efficiently, extend the useful life of terminal box.
To achieve the object of the present invention, a kind of photovoltaic component terminal box with high efficient heat dissipation performance of the present invention comprises terminal box body and electric connection line, the multiple splicing ears be connected with photovoltaic module busbar are disposed with in described box body, comprise the first splicing ear, second splicing ear, 3rd splicing ear and the 4th splicing ear, described second splicing ear is provided with chip diode to the 4th splicing ear, described diode is electrically connected with the splicing ear adjoined respectively and keeps the polarity after connecting consistent, wherein, be located at second splicing ear in terminal box centre position larger than the area of plane of the first splicing ear and the 4th splicing ear that are positioned at terminal box both sides with the area of plane of the 3rd splicing ear.
Preferably, the area of plane which is provided with the 4th splicing ear of diode being in a side than another side its on not arrange the area of plane of the first splicing ear of diode large.
Preferred again, the second described splicing ear is L-type, and the 3rd splicing ear is Z-type, described second splicing ear and the 3rd splicing ear staggered, and the arragement direction of diode is between the two vertical with the arragement direction of other diodes.
Preferred again, the area of plane of the second described splicing ear is equal with the area of plane of the 3rd splicing ear.
The photovoltaic component terminal box with high efficient heat dissipation performance of the present invention, according to the arrangement situation of junction box diode, different sizes and structure is devised to the binding post of diverse location, be the not only efficient and heat radiation of the heat radiation of junction box evenly, avoid the generation of localized hyperthermia, ensure that the useful life of terminal box.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Figure 1 shows that the structural representation with the photovoltaic component terminal box of high efficient heat dissipation performance of one embodiment of the invention;
Figure 2 shows that the structural representation with the photovoltaic component terminal box of high efficient heat dissipation performance of another embodiment of the present invention.
Embodiment
By feature of the present invention and advantage, details are as follows by reference to the accompanying drawings:
The structural representation with the photovoltaic component terminal box of high efficient heat dissipation performance of one embodiment of the invention as shown in Figure 1, described terminal box comprises box body 10 and electric connection line 20, the multiple splicing ears be connected with photovoltaic module busbar are disposed with in described box body 10, comprise the first splicing ear 102, second splicing ear 104, 3rd splicing ear 106 and the 4th splicing ear 108, described second splicing ear 104 is provided with chip diode 14 to the 4th splicing ear 108, described diode 14 is electrically connected with the splicing ear adjoined respectively and keeps the polarity after connecting consistent, wherein, be located at second splicing ear 104 in terminal box centre position and the area of plane of the 3rd splicing ear 106 larger than the area of plane of the first splicing ear 102 and the 4th splicing ear that are positioned at terminal box both sides.
In above-described embodiment, due to be positioned at middle splicing ear be provided with diode and also due to the radiating effect in centre position more difficult than terminal box two side position, therefore, the area of plane of the splicing ear in terminal box centre position arranges larger by the present invention, can ensure the uniformity that junction box dispels the heat as far as possible; In the scheme that another is more optimized, because the 4th splicing ear 108 being in a side is provided with diode, and the first splicing ear of another side is not arranged diode, in order to reach average radiating effect, can further the area of plane of the 4th splicing ear be set to larger than the area of plane of the first splicing ear.
The structural representation with the photovoltaic component terminal box of high efficient heat dissipation performance of the embodiment that another is more optimized of the present invention as shown in Figure 2, the second splicing ear 104 ' in described terminal box designs l-shaped, and the 3rd splicing ear 106 ' is designed to Z-type, so the second splicing ear both can be made roughly the same with the area of the 3rd splicing ear, and can by the second splicing ear and the 3rd splicing ear staggered, diode is between the two arranged with the arragement direction being different from other diodes, also the heat dissipation direction by junction box splicing ear is adjusted to different directions, so, the heat radiation of junction box can be made more all efficiently even.
The present invention, according to the arrangement situation of junction box diode, devises different sizes and structure to the binding post of diverse location, to reaching efficient and uniform object of dispelling the heat, avoiding the generation of localized hyperthermia, the useful life of terminal box also can be made elongated.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
