Description
Technical field
The utility model relates to the technical field of cooling system, specifically the cooling system of DC lightning prevention power distribution cabinet counnter attack diode, particularly its system syndeton.
Background technology
The modern civilization of being started by the industrial revolution; all be based upon large scale mining, use on the basis of fossil fuel; but be accompanied by the continuous consumption of fossil fuel, the mankind have come to realise and must face potential energy crisis---fossil energy is exhausted at last.Countries in the world are all at the new green power of actively seeking alternative fossil fuel, and solar photovoltaic technology is to utilize " photovoltaic effect " that light is directly converted to electric energy, and whole transfer process is without discharge, are the green energy resources of the most clean, environmental protection.And photovoltaic distribution cabinet is a kind of smart machine being applied in Intelligent photovoltaic electricity generation system for photocell tandem and peripheral auxiliary element are monitored, be to be accompanied by the large-scale application of photovoltaic generation and a novel product producing.General pv grid-connected plant mainly by 1, photovoltaic battery array, 2, photovoltaic distribution cabinet, 3, inverter three parts form, by array, accept illumination and produce direct current, electric current outputs to power distribution cabinet wealthy stream in parallel, then by a plurality of power distribution cabinets, outputs to inverter, after final inverter is converted to alternating current direct current, is transported to electrical network or after boosting, carries out grid-connected.In confluxing in system of power distribution cabinet, for fear of damaging on the contrary storage battery or photovoltaic DC power supply because of positive and negative the connecing of power line of input, and the phenomenon generation of power in service refluence, in more power distribution cabinet system, need to install additional counnter attack diode.Due to the PN junction characteristic of diode, in the process of large electric current generating, must give out larger heat, if can not effectively get rid of heat, in power distribution cabinet, by temperature rise aggravation, directly affect interior other devices of cabinet and cause device failure.
Summary of the invention
The purpose of this utility model is to provide the cooling system of DC lightning prevention power distribution cabinet counnter attack diode, can be applicable to, in the project of large-sized solar power station, realize high efficiency and heat radiation.
To achieve these goals, the technical solution of the utility model is: the cooling system of DC lightning prevention power distribution cabinet counnter attack diode, is characterized in that being provided with in described cooling system:
One main fin, for heat conduction and heat radiation;
The one main busbar that confluxes, this main busbar that confluxes is arranged at main fin surface, for by the output short circuit of counnter attack diode;

Wherein:
1, main fin;
2, the main busbar that confluxes;
3, counnter attack diode;
4, Forced discharge fan.
Embodiment
With reference to the accompanying drawings, the utility model is further described.
The utility model discloses the cooling system of DC lightning prevention power distribution cabinet counnter attack diode, it is different from prior art and is to be provided with in described cooling system: a main fin, for heat conduction and heat radiation; The one main busbar that confluxes, this main busbar that confluxes is arranged at main fin surface, for by the output short circuit of counnter attack diode; Some counnter attack diodes, all counnter attack diode close-packed arrays shapes are distributed in the main fin surface of the main busbar both sides of confluxing, and the output of all counnter attack diodes is all connected to the main busbar that confluxes, and the busbar that confluxes is by all diode output short circuits.
In the specific implementation, the upper end of described main fin and bottom are respectively provided with two Forced discharge fans.
In the specific implementation, described Forced discharge fan is arranged at the place, the upper and lower two ends of main fin at the upper and lower two ends of main busbar of confluxing, and the air draft direction of described four Forced discharge fans is identical.
As shown in fig. 1, the function that the cooling system of DC lightning prevention power distribution cabinet counnter attack diode is realized is as follows: 1., in order to improve radiating effect, by all counnter attack diode close installation, in a main fin, area of dissipation increases, radiating effect promotes, and produces good convection effect.Compare discrete mounting means, device is installed simple, fin cost simultaneously.2. for improving radiating effect, at fin two ends, install forced-ventilated fan additional, increase flow greatly.By the direct short circuit of the output of diode in main busbar of confluxing of central authorities, improved installation effectiveness, shortened the length of main busbar, reduce equipment and materials cost.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that the concrete enforcement of the utility model is confined to above-mentioned these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
