Description
Technical field
The utility model relates to a kind of solar module manufacturing technology, is specifically related to a kind of photovoltaic component terminal box heat abstractor.
Background technology
Solar module (photovoltaic module) absorbs sunlight and converts electric energy output to.Power output device is terminal box, the primary conductive element of junction box is all copper product, the resistivity of copper is low, power loss is little, price is relatively cheap and its ductility is good, easy to process, but because copper is more active, easy and other materials react, so, the protection of cupric article is just seemed very important.Show in terminal box to be exactly the design of the aspects such as water proof and dust proof grade, heat dispersion.Junction box pours into casting glue protection live part usually, then buckle closure (having covered a circle rubber seal), stops the erosion of steam, dust.Photovoltaic module can along with heat release in power generation process, and heat can be put aside at junction box, and temperature is very high.Due to PPO or the PC material of box body normally black, the more difficult release of thermal reservoir, even if casting glue has selected white colloidal, also can produce very high temperature.The too high copper part of tray interior that just can cause of temperature accelerates chemical reaction corrosion occurs, and forms verdigris.The contact resistance that verdigris can cause solar components to generate electricity and export increases, assembly power output entire lowering.In addition, junction box temperature is too high also slowly can cause sealing ring on junction box body and cell material slowly ageing failure itself.Sealing effectiveness is deteriorated, and waterproof and dustproof ability declines, and causes solar module to lose efficacy, and generating effect dies down, and even loses power generation performance.Therefore, how to discharge the heat of junction box, be a difficult point always.Add fan in terminal box outside or take the modes such as water quench all greatly can increase the cost of photovoltaic module, and implement pretty troublesome, especially power station is built at the area application photovoltaic module of lack of water, arid, few wind, these types of cooling implement all can not be desirable, just adopt white casting glue so now general, there is no good terminal box cooling measure.
Utility model content
The utility model is solve existing photovoltaic component terminal box to adopt the casting glue of white to reduce heat accumulation, and radiating effect is bad, causes the problem that terminal box useful life is low, and then provides a kind of photovoltaic component terminal box heat abstractor.
The utility model is solve the problems of the technologies described above the technical scheme taked to be:
Described device of the present utility model comprises terminal box, connector cover, conductive graphite paper, conductive graphite cream and aluminium radiator, junction box pours into white casting glue, one end of conductive graphite paper is inserted in colloid, the other end of conductive graphite paper is positioned at outside terminal box and is connected with conductive graphite cream, conductive graphite cream is fixed with aluminium radiator, and connector cover is fastened on the opening part of terminal box.
The utility model has following beneficial effect:
One, photovoltaic module and solar panel, can heat be produced at work, conductive graphite paper 3 by the heat conduction in terminal box out, by the bonding aluminium radiator of conductive graphite cream of tail end, by heat loss in atmosphere, thus improve useful life of terminal box.
Two, the utility model structure is simple, cost is low.
