Abstract

The utility model provides a photovoltaic combiner box with an anti-reflection diode, and solves the problems that a photovoltaic combiner box with an anti-reflection diode in the prior art is poor in heat radiation effect in box body, low in box body protection level, and low in service life of a radiation aluminium piece externally arranged outside the box body; package and transportation are convenient; the photovoltaic combiner box comprises the box body the anti-reflection diode arranged in the box body; the features are that an isolation plate is arranged in the box body and divides internal space of the box body into a radiation isolation chamber and a photovoltaic combiner chamber; the anti-reflection diode is arranged on a plate wall, positioned on the photovoltaic combiner chamber side, of the isolation plate; a plate wall, positioned on the radiation isolation chamber side, of the isolation plate is provided with a radiation aluminium plate.

Description

A kind of photovoltaic combiner box with counnter attack diode

Technical field

The utility model relates to photovoltaic technical field of new energies, is specially a kind of photovoltaic combiner box with counnter attack diode.

Background technology

At photovoltaic new energy field, mostly be, at the box body wall that counnter attack second tube sheet position is installed, sawtooth pattern heat radiation aluminium block 11 is installed outward with the photovoltaic combiner box of counnter attack diode at present, heat counnter attack diode 2 power consumptions being produced by this sawtooth pattern heat radiation aluminium block 11 dispels the heat, see Fig. 1, its shortcoming aluminium block that is to dispel the heat is installed on the degree of protection of destructible casing on the box body wall of photovoltaic combiner box, and because heat radiation is exposed in air the normal phase of aluminium block, thereby the aluminium block that is subject to dispel the heat after erosion by wind and rain is easily caused radiating effect to decline by weathering, and also greatly shorten useful life; Simultaneously due to heat radiation aluminium block, to protrude from header box external, the entire package transport difficulty of the casing that causes confluxing.

Summary of the invention

For the problems referred to above, the utility model provides a kind of photovoltaic combiner box with counnter attack diode, it can solve the existing heat radiation aluminium block low problem in useful life that photovoltaic conflux casing radiating effect is poor, casing degree of protection is low, casing is external with counnter attack diode, and is convenient to packed and transported.

Its technical scheme is such, it comprises casing, counnter attack diode, described counnter attack diode is installed in described casing, it is characterized in that: in described casing, be provided with division board, described division board is heat radiation isolation ward and photovoltaic conflux chamber by described box house space obstacle, described counnter attack diode is installed on the wooden partition that described division board is positioned at described photovoltaic conflux chamber one side, and described division board is positioned on the wooden partition of a side of described heat radiation isolation ward heat-dissipating aluminium plate is installed.

It is further characterized in that:

Be positioned at described heat radiation isolation ward, with the tank wall of the just right described casing of described division board on have some louvres;

On the described tank wall that has some louvres, just the position of described louvre is provided with to outside flange, described louvre and described flange form louvered shutter structure;

The upper and lower end of described flange is connected with described tank wall, the front and back ends hollow out of described flange;

Described flange from the upper end of described louvre to described tank wall outside and to downward-extension.

Compare with the existing photovoltaic conflux box structure with counnter attack diode, the utility model beneficial effect is: it is heat radiation isolation ward and photovoltaic conflux chamber by division board by spatial separation in case, counnter attack diode is installed on the wooden partition that division board is positioned at photovoltaic conflux chamber one side, division board is positioned on the wooden partition of a side of heat radiation isolation ward heat-dissipating aluminium plate is installed, heat counnter attack diode power consumption being produced by the heat-dissipating aluminium plate in isolation ward dispels the heat, because heat-dissipating aluminium plate is closed in compartment, therefore effectively ensured the degree of protection of whole photovoltaic combiner box, and avoid heat-dissipating aluminium plate to be directly exposed to outside casing, extend the useful life of heat-dissipating aluminium plate, also be convenient to packaging and the transport of whole photovoltaic combiner box simultaneously, in addition, heat radiation isolation ward, with the tank wall of the just right casing of division board on some louvres of being provided with, heat-dissipating aluminium plate in heat radiation isolation ward directly exchanges heat radiation with heat radiation isolation ward outer air by some radiator windows, thereby further ensures stability and the normal work of indoor other components and parts of photovoltaic conflux, and have on the tank wall of some louvres, just the position of louvre be provided with to outside flange, louvre and flange form louvered shutter structure, its to external world sleet dust carry out effective barrier effect, reduce the erosion to heat-dissipating aluminium plate in heat radiation isolation ward, further extend the useful life of heat-dissipating aluminium plate, ensure radiating effect.
