Abstract
The utility model relates to a dustproof shielding can for an inverter circuit. The dustproof shielding can comprises an inverter circuit board disposed on the bottom of an electric welding machine, and a radiator on the inverter circuit board. An end of the radiator is provided with a fan. An air inlet end of the radiator is provided with a wind gathering cover, and the other end is provided with a wind outlet cover. The other two sides of the radiator, that is, an upper part and a lower part of the radiator, are provided with baffles. The baffles, the wind gathering cover, and the wind outlet cover isolate the inverter circuit board on the radiator into an independent sealed space. The dustproof shielding cans are made into various sizes, being suitable for different radiators. The dustproof shielding can is simple in manufacturing and processing, and convenient in installation. After installation, service life of the inverter circuit is doubled, maintenance operation is reduced, and money is saved for an enterprise.
Description
Technical field
The utility model relates to the protective device of inverter circuit plate in electric welding machine, specifically the dustproof cage of a kind of inverter circuit.
Background technology
In electric welding machine, because the electric current of inverter circuit is very large, need to carry out brute force heat radiation, at the rear of circuit board, be provided with radiator.Conventional radiator is by heat conducting base and by heat conducting base, extend a plurality of radiating fins that form and form, and by the base plane of heat conducting base, power device is absorbed heat, then is dispelled the heat by other surface and the fin surface on it of heat conducting base.One end in radiator fins is provided with fan, carries out blowing heat radiation in real time.Existing inverter circuit plate is to be placed on radiator, and due to electric welding machine work under bad environment, the air of fan inspiration is with a large amount of dust, and directly blow to radiator, owing to there is no the device of wind gathering, electric welding machine inside distinguished and admirable to confusion, causes inner laying dust serious.After time is permanent, the phenomenon that is easily short-circuited, and damage equipment, therefore need to regularly clear up.In actual use, staff often can not clear up in time, and the life-span of electric welding machine is significantly reduced.
Summary of the invention
The purpose of this utility model, is exactly the problem existing for solving prior art, and has designed the dustproof cage of a kind of inverter circuit, makes electric welding machine inside have stable wind direction, protection inverter circuit plate.
The technical solution of the utility model is: a kind of inverter circuit cage that prevents dust, comprise and be arranged on the inverter circuit plate of electric welding machine bottom and the radiator on inverter circuit plate, radiator one end is provided with fan, and the air intake of described radiator is provided with wind gathering cover, and the other end is provided with outlet housing; The other both sides of described radiator are that the above and below of radiator is provided with baffle plate; Described baffle plate, wind gathering cover and outlet housing are isolated into an independently seal cavity by the inverter circuit plate on radiator.
Described wind gathering cover cross section is square, the pre-large post-small pyramidal structure that its surrounding sidewall is cambered surface.
Described wind gathering cover and outlet housing are identical structure.
Described baffle plate, wind gathering cover and outlet housing are plastics or electro-insulating rubber.
Described baffle plate, wind gathering cover and outlet housing are screwed on radiator.
The beneficial effects of the utility model can draw by such scheme: owing to being provided with wind gathering cover between radiator and fan; make cooling air can from fan blows out, all enter the fin gap of radiator; can increase air quantity; and the inverter circuit seal isolation on radiator is protected; effectively place and fall into dust, increased the useful life of equipment.The utility model can be made all kinds of sizes and be applicable to different radiators, makes processing simple, easy for installation, makes extend one times the useful life of inverter circuit after installation, has reduced maintenance work, to enterprise, has saved fund.
As can be seen here, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of wind gathering cover.
Wherein, 1 is electric welding machine, and 2 is fan, and 3 is wind gathering cover, and 4 is inverter circuit plate, and 5 are, 6 is radiator, and 7 is outlet housing.
embodiment:
In order to understand better the utility model, below in conjunction with accompanying drawing, explain in detail execution mode of the present utility model.
Embodiment: as shown in Figure 1, the inverter circuit cage that prevents dust, comprises and is arranged on the inverter circuit plate 4 of electric welding machine 1 bottom and the radiator 6 on inverter circuit plate 4, radiator 6 one end are provided with fan 2, the air intake of described radiator 6 is provided with wind gathering cover 3, and the other end is provided with outlet housing 7; The other both sides of described radiator 6 are that the above and below of radiator is provided with baffle plate 5; Described baffle plate 5, wind gathering cover 3 and outlet housing 7 are isolated in one independently in seal cavity by the inverter circuit plate 4 on radiator 6.Wind gathering cover 3 and outlet housing 7 are identical structure.Wind gathering cover 3 cross sections are square, the pre-large post-small pyramidal structure that its surrounding sidewall is cambered surface.Baffle plate 5, wind gathering cover 3 and outlet housing 7 are plastics or electro-insulating rubber, are screwed on radiator 6.
Above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection range of the present utility model.
