Description
Technical field
This utility model relates to photovoltaic module technical field, specifically a kind of modular photovoltaic junction box.
Background technology
Along with the exhaustion day by day of natural resources in global range, the mankind it is becoming increasingly recognized that solar energy is a kind of energy demand prediction inexpensively cleaned again.Nowadays the important development trend that countries in the world are using the commercial development of solar energy and utilization as the energy.At present, heliotechnics main application fields has: solar thermal collector, solar thermal power generation, solar energy power generating, solar seawater desalination, solar airconditioning, solar electric vehicle, solar building, solar hydrogen making, solar energy illuminating light etc..The solar energy resources of China is very abundant, and theoretical reserves reach annual 1700000000000 tons of standard coals, and the prospect that solar energy resources develops is boundless.And rosette is as a vitals of solar photovoltaic battery component, it is the adapter of photovoltaic module and load, is a comprehensive design, although simple in construction, most important.
Traditional junction box structure design includes lid, box body, diode component, input contact and output lead.Input contact according to the insidious connection rosette of solar module, electric current is exported through the outfan of output lead by the bypass diode in box body, and the box body of this rosette itself is bigger than normal, improves material cost accordingly；Diode component in box body is discrete component, wire insert connect fixing；With air as heat insulation medium, radiating effect is often poor, and power attenuation is also bigger than normal；Furthermore discrete component is connected fixing mode by wire insert, make contact resistance become big, to battery component itself also band serve potential safety hazard.
Summary of the invention
Problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of modular junction box structure, and this junction box structure can effectively dispel the heat, and each electrical equipment of firm connection.
For solving the problems referred to above, the technical solution adopted in the utility model is: a kind of modular photovoltaic junction box, including box body, an aluminium base is included in box body, described aluminium base arranges a layer insulating, the place connected at electric elements arranges copper paster, and described aluminium base arranges change-over circuit district and warning circuit district, and box body also sets up the fixing pad of a sealing.
Preferably, seal fixing pad to be made up of heat conductive silica gel；Electric elements on aluminium base be able to be played fixation by its shape and the shape complementarity of electric elements on aluminium base.
Preferably, described box body has louvre.
Preferably, described box body has guidewire port.
Preferably, described box body outer layer coating rush-resisting material.
The beneficial effects of the utility model are in that: photovoltaic junction box is carried out modularized design, electric elements are arranged on aluminium base, and according to function by electric elements subregion, arrangement according to electric elements arranges the fixing pad of sealing, electric elements are carried out good fixing, seal fixing pad adopts heat conductive silica gel to make simultaneously, does not affect the heat radiation of electric elements；Box body arranges louvre and also allows for heat radiation, its cooling measure also have electric elements are arranged on aluminium base, it is commonly known that aluminum be heat good conductor, the heat of electric elements can Quick diffusing to aluminium base, and then it is dispersed on box body by sealing fixing pad, distributed by box body.Box body outer layer is coated with rush-resisting material, when box body is placed on the external world, extends the service life of photovoltaic junction box.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model.
Wherein accompanying drawing labelling is as follows:
1, box body；2, aluminium base；3, insulating barrier；4, copper paster；5, change-over circuit district；6, warning circuit district；7, fixing pad is sealed；8, louvre；9, guidewire port.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further:
A kind of modular photovoltaic junction box, including box body 1, an aluminium base 2 is included in box body 1, described aluminium base 2 arranges a layer insulating 3, the place connected at electric elements arranges copper paster 4, described aluminium base 2 arranges change-over circuit district 5 and warning circuit district 6, box body 1 also sets up the fixing pad 7 of a sealing.
Seal fixing pad 7 to be made up of heat conductive silica gel；Electric elements on aluminium base 2 be able to be played fixation by its shape and the shape complementarity of electric elements on aluminium base 2.Box body 1 has louvre 8, described box body 1 has guidewire port 9, described box body 1 outer layer coating rush-resisting material.
The beneficial effects of the utility model are in that: photovoltaic junction box is carried out modularized design, electric elements are arranged on aluminium base 2, and according to function by electric elements subregion, arrangement according to electric elements arranges the fixing pad 7 of sealing, electric elements are carried out good fixing, seal fixing pad 7 employing heat conductive silica gel to make simultaneously, do not affect the heat radiation of electric elements；Box body 1 arranges louvre 8 and also allows for heat radiation, electric elements are also arranged on aluminium base 2 by its cooling measure, it is known that aluminum is the good conductor of heat, the heat of electric elements can Quick diffusing to aluminium base 2, and then it is dispersed on box body 1 by sealing fixing pad 7, distributed by box body 1.Box body 1 outer layer is coated with rush-resisting material, when box body 1 is placed on the external world, extends the service life of photovoltaic junction box.
Change-over circuit district 5 on aluminium base converts light energy into electric energy and stores, and warning circuit district 6 is by the indexs such as the temperature in monitoring rosette, the good operation of monitoring rosette.
The above, be only preferred embodiment of the present utility model, is not the restriction that this utility model is made other form.Any those skilled in the art are changed or are modified as the Equivalent embodiments of equivalent variations possibly also with the technology contents of the disclosure above.But every without departing from technical solutions of the utility model content, according to any simple modification, equivalent variations and remodeling that above example is made by structure of the present utility model and operation principle, still fall within the protection domain of technical solutions of the utility model.
