Abstract
The utility model relates to a photovoltaic anti-thunder combiner box with a heat radiator installed on the external of a casing. The photovoltaic anti-thunder combiner box comprises a combiner box front panel, a combiner box back panel, a combiner box left side panel, a combiner box right side panel, a combiner box top panel and a combiner box bottom panel. The outer surface of the combiner box back panel is fixedly provided with a reverse-preventing diode radiator. The photovoltaic anti-thunder combiner box adopts the external heat radiator to improve operation stability of products, reduce heat accumulation of equipment in normal operation, greatly prolong the service life of components and reduce operational and maintenance cost.
Description
Technical field
The utility model relates to a kind of solar power generation control cabinet, and especially a kind of heat abstractor is installed in the photovoltaic lightning protection header box of casing outside.
Background technology
Along with the continuous development of human society, increasing to the demand of the energy.Traditional energy is fewer and feweri, and cost is in continuous rising.Traditional energy is serious day by day to environment damage simultaneously.Solar energy more and more is much accounted of as a kind of clean energy resource.
For the large-sized photovoltaic grid-connected system, in order to reduce connecting line between photovoltaic module and the inverter, maintain easily the raising reliability, generally need between photovoltaic module and inverter, increase the direct current collector-shoe gear, this device is exactly photovoltaic lightning protection header box.Use the photovoltaic header box, the user can be according to the direct voltage scope of inverter input, the identical photovoltaic module of the specification of some is composed in series 1 photovoltaic module tandem, again several tandems are inserted photovoltaic array lightning protection header box, by exporting behind lightning protection device and the circuit breaker, made things convenient for the access of back level inverter.Along with the demand of follow-up photovoltaic system, released a kind of photovoltaic lightning protection header box that the counnter attack diode of anti-counter-function is arranged.
Prevent the photovoltaic lightning protection header box of counter-function for this band before, because the operating characteristic of counnter attack diode and the operating characteristic of circuit breaker (thermo magnetic trip release), in the process of system's generating, can produce a large amount of heats, and the heat abstractor mounting means of diode is at box house, thereby cause heat build-up at box house, when heat build-up arrives to a certain degree, will influence the operate as normal of equipment, in the useful life of minimizing equipment, cause the equipment can not normal power generation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of natural heat dissipation ability of solar power generation photovoltaic header box, the stability that improves the operation of photovoltaic header box and inner components and parts useful life, heat abstractor of reduction maintenance cost of can improving greatly to be installed in the photovoltaic lightning protection header box of casing outside.
The technical scheme that provides according to the utility model, described heat abstractor is installed in the photovoltaic lightning protection header box of casing outside, comprise header box front panel, header box backplate, header box left plate, header box right plate, header box top panel and header box bottom panel, at the outer surface of described header box backplate counnter attack diode radiating device is arranged fixedly.
Described counnter attack diode radiating device is arranged near on the header box backplate of top edge midline position.
The utlity model has following advantage:
1, adopt external heat abstractor to improve the stability of product operation;
2, adopt external heat abstractor to reduce the accumulation of heat of equipment when operate as normal;
3, adopt external heat abstractor to prolong components and parts useful life greatly, reduce operation maintenance cost.
Description of drawings
Fig. 1 is structure schematic diagram of the present utility model.
Fig. 2 is Facad structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: heat abstractor is installed in the photovoltaic lightning protection header box of casing outside, comprise header box front panel 1, header box backplate 2, header box left plate 3, header box right plate 4, header box top panel 5 and header box bottom panel 6, at the outer surface of described header box backplate 2 counnter attack diode radiating device 7 is arranged fixedly.
Described counnter attack diode radiating device 7 is arranged near on the header box backplate 2 of top edge midline position.
The utility model is on the basis that guarantees original photovoltaic header box operate as normal, counnter attack diode radiating device 7 is installed on the outer surface of header box backplate 2, it is the outside that counnter attack diode radiating device 7 is installed in header box, improve the natural heat dissipation ability of solar power generation photovoltaic header box so greatly, make header box under exceedingly odious environment, still keep reliability, and then improve stability and the inner components and parts useful life of the operation of photovoltaic header box, reduce maintenance cost.
