Compared with the technology of the prior art, the direct current lightning protection power distribution cabinet anti-reverse diode heat dissipation system can be applied to multiple kinds of direct current lightning protection power distribution cabinets, the diodes can be greatly improved in heat dissipation property, the inner part of a power distribution cabinet can be lowered in temperature rise, devices in the cabinet can be improved in operation stability, and connection material cost and labor cost for installation are lowered through an integrating installation mode.
Description
Technical field
The utility model relates to a kind of diode radiating system of DC power distribution cabinet, especially relates to a kind of cooling system of DC lightning prevention power distribution cabinet counnter attack diode.
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, and the mankind have come to realise must be exhausted at last in the face of potential energy crisis-fossil energy.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 directly is 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 be applied in the 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 is comprised of photovoltaic battery array, photovoltaic distribution cabinet, inverter three parts, accept illumination by array and produce direct current, electric current outputs to power distribution cabinet wealthy stream in parallel, then output to inverter by a plurality of power distribution cabinets, after final inverter is converted to alternating current to direct current, is transported to electrical network or carries out grid-connected after boosting.In the system of confluxing of power distribution cabinet, damage on the contrary storage battery or photovoltaic DC power supply for fear of positive and negative the connecing of power line because of input, and the phenomenon generation of power in service refluence, need to install additional the counnter attack diode in more power distribution cabinet system.Due to the PN junction characteristic of diode, must give out larger heat in the process of large electric current generating, if can not effectively get rid of heat, in power distribution cabinet, by the temperature rise aggravation, directly affect interior other devices of cabinet and cause device failure.
The utility model content
The purpose of this utility model is exactly the cooling system that a kind of perfect heat-dissipating, DC lightning prevention power distribution cabinet counnter attack diode that installation cost is low are provided in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of cooling system of DC lightning prevention power distribution cabinet counnter attack diode, this system comprises main fin, the busbar that confluxes, counnter attack diode and Forced discharge fan, the described busbar that confluxes is located on main fin, described counnter attack diode is provided with a plurality of, all be listed as on the main fin that is located at the busbar both sides of confluxing and be connected with the busbar that confluxes, described Forced discharge fan is located at the two ends of main fin.
The output of described counnter attack diode all is connected with the busbar that confluxes.
Described counnter attack diode is provided with 8 altogether.
Described Forced discharge fan is provided with 4 altogether, 2 tops that are located at main fin wherein, other 2 bottoms that are located at main fin.
Compared with prior art, the utility model can be applicable to polytype DC lightning prevention power distribution cabinet, greatly improves the heat dispersion of diode, reduces temperature rise in power distribution cabinet, improves the operation stability of device in cabinet.Simultaneously, integrated mounting means also reduces the connecting material cost, reduces the cost of labor of installing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
A kind of cooling system of DC lightning prevention power distribution cabinet counnter attack diode, as shown in Figure 1, this system comprises main fin 2, the busbar 3 that confluxes, counnter attack diode 1 and Forced discharge fan 4, the busbar 3 that confluxes is located on main fin 2, counnter attack diode 4 is provided with 8, all row are located on the main fin 2 of busbar 3 both sides of confluxing, the output of counnter attack diode 1 directly is connected with the busbar 3 that confluxes, Forced discharge fan 4 is provided with 4 altogether, 2 tops that are located at main fin 2 wherein, other 2 bottoms that are located at main fin 2, for increasing flow, improve radiating effect.
The function that this utility model realizes 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, and radiating effect promotes, and produces good convection effect.Compare the discrete mounting means, device is installed simple, the fin cost simultaneously.
2. for improving radiating effect, at the fin two ends, install the 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 the equipment and materials cost.
