The specific embodiment
Below, specifically describe preferred implementation of the present invention with reference to accompanying drawing.
One embodiment of the supply unit that Fig. 1～3 expressions are involved in the present invention.The supply unit A of present embodiment is used to export needed big electric current of for example arc welding and high voltage.Supply unit A uses under the many atmosphere environment of dust such as factory usually.
Supply unit A possesses basal component 1, casing cover 2, the various parts 3 that constitute power circuit, radiator 5, first dividing plate 6, two second partition 7A, 7B, and the fan 8 of cooling usefulness.In device, be provided with by the part of the part of basal component 1, first dividing plate 6, and the wind path 9 of the empty shape that surrounds of second partition 7A, 7B.This wind path 9 extends along the fore-and-aft direction of supply unit A (below, be called " F direction ") lengthwise shape.In addition, in device, be provided with in the outer side of wind path 9 by the part of the part of the part of basal component 1, casing cover 2, first dividing plate 6, and the configuration space B1 of the parts 3 that surround of second partition 7A, 7B and the configuration space B2 of fan 8.
First dividing plate 6 is for example metal system, the space in the device is divided into the space of the upper and lower.First dividing plate 6 is and the rectangular shape of basal component 1 with the degree size, in the above-below direction centre position of casing cover 2 horizontal arrangement.The configuration space B1 of first dividing plate, 6 component parts 3, the configuration space B2 of fan 8, and the top wall in the space of wind path 9 these lower floors.Need to prove,, also be provided with parts etc. in the space on upper strata though do not illustrate especially.
Next, the effect of above-mentioned supply unit A is described.
Supply unit A exports the big electric current and the high voltage of welding usefulness in action, cause its temperature to raise thereupon a plurality of parts 3 heatings.The heat of each parts 3 also directly transmits with respect to radiator 5 except that transmitting in the air of configuration space B1.At this moment, because it is big to compare thermal conductivity factor as the raw-material metal of radiator 5 and air, therefore the heat that produces at each parts 3 transmits well to radiator 5 efficient.
During fan 8 work, the air of suction inlet 80 peripheries is taken into by fan 8, and these air are sent in wind path 9 from outlet 81 along the direction that the length direction with wind path 9 intersects as wind.Follow in this, extraneous air flows into to configuration space B2 from suction hole portion 20.
At this moment, as shown in Figure 3, be positioned at the inflow resistance that the locational suction hole portion 20 of leaving suction inlet 80 becomes air, producing enough pressure differentials near the suction inlet 80 and between near the suction hole portion 20.Thus, become negative pressure in the configuration space B2.The air that contains dust that is drawn in the configuration space B2 from suction hole portion 20 flows when suction inlet 80 Minus speed is detained, and dust is fully removed therebetween, and fan 8 can be taken into the amount air still less of dust.Therefore, suppress effectively from the dust of fan 8 in wind enters wind path 9.
The wind that is sent in the wind path 9 from fan 8 directly contacts with radiator 5, flows to the length direction both ends of wind path 9 along fin 51.At this moment, because wind contacts well with a plurality of fin 51 efficient, therefore capture a large amount of heats from the surface of each fin 51.In addition, the length direction both ends of the wind direction wind path 9 that blows out from fan 8 are divided into two, flow in the distance of weak point relatively and discharge to the outside from the outlet 90 of both sides.Therefore, the resistance force diminishes of the wind that flows in wind path 9 is promptly discharged wind from exporting 90.Thus, with the air cooling well of radiator 5 efficient, and parts 3 also efficient are cooled off well via this radiator 5.
Because fan 8 is positioned at the length direction pars intermedia of wind path 9, therefore be positioned at the periphery of this fan 8 just along a plurality of parts 3 of wind path 9 configurations.That is, the fan 8 on the length direction of wind path 9 is compared weak point with the distance of each parts 3 with the length of wind path 9 integral body, and each parts 3 is configured in the position closer with respect to fan 8.Also a plurality of parts 3 efficient can be cooled off well by the such fan 8 and the position relation of parts 3.Therefore, do not need to determine the position of each parts 3 according to the heat generation characteristic of parts 3, can be with the configuration freely to a certain extent of a plurality of parts 3.
In addition, in above-mentioned supply unit A, the resistance of the wind that flows in wind path 9 reduces, and therefore can realize the miniaturization and the lightweight of fan 8, and then realizes the low noiseization and the low consumpting powerization of fan 8.
When the utilization of above-mentioned supply unit A, because to a certain degree dust in air enters wind path 9, becomes following state easily in the wind path 9 after the therefore long time uses: dust enters and is collected in the gap etc. of fin 51 of radiator 5.If use supply unit A under such state, then the radiating effect of radiator 5 weakens, even parts 3 do not have sufficiently cooledly, and consequently, fire damage may take place parts 3.Therefore, during utilization, use not shown jet gun to blow away the such dedusting operation of dust in the wind path 9 termly.
In the dedusting operation of having used jet gun, pull down casing cover 2 and make the outlet 90 of wind path 9 become the state that exposes from basal component 1, thereafter, with the air ejiction opening of jet gun from a side's of for example wind path 9 outlet 90 towards inner and spray compressed air.Compressed air becomes along the jet flow of the length direction of wind path 9, and the dust that is deposited in 51 of fin for example powerfully is blown out to the opposing party's outlet 90.
In addition, the compressed-air actuated injection direction that ejects from jet gun becomes along the direction of the length direction of wind path 9, promptly becomes the direction of intersecting with the air blast direction of fan 8.Thus, the compressed air from jet gun becomes the jet flow that is difficult for the blade of fan 8 is directly acted on blast.Therefore, when the dedusting operation of having used jet gun, can the generation meeting because of compressed-air actuated strong jet flow makes the situation of fan 8 high speed reverse rotation, do not have the blade that makes this fan 8 and the possibility of swivel bearing breakage.
And then, according to above-mentioned supply unit A owing to suppress from the dust of fan 8 in wind enters into wind path 9, therefore can extend to carry out till the dedusting operation during, improve efficiency of movement.

As shown in figure 10, second wind path 9 ' is used to from the wind of second fan 8 ' radiator 5 be cooled off, and with these wind direction length direction both ends guiding.Second wind path 9 ' with the upper portion of second partition 7A and second partition 7B for opposed a pair of vertical wall on the width so that with the horizontal component of the part of first dividing plate 6 and the 3rd dividing plate 7C for opposed top wall and base wall on above-below direction surround, form the cross section rectangular shape.The length direction both ends of second wind path 9 ' become the outlet 90 ' that wind goes out.Be sent to wind in second wind path 9 ' from second fan 8 ' and directly contact with radiator 5 and be divided into two, capture a large amount of heats from this radiator 5 and also blow out from exporting 90 ' simultaneously to the length direction both ends of second wind path 9 '.That is, also short than the length of second wind path, 9 ' integral body to exporting the distance that wind flowed till 90 ' from second fan 8 ' in second wind path 9 ', these wind are promptly discharged to the outside.Thus, electronic unit 30 is cooled off by efficient well via radiator 5.From export the 90 ' wind that blows out by being arranged on casing cover 2 face portion 2C and the air vent portion 21 of the 2D of back side portion promptly blow out to the outside.
Next, the effect of above-mentioned supply unit A1 is described.
In the action of supply unit A1, electronic unit 30 and electric component 31 generate heat and cause the temperature of these parts to raise.The heat of electronic unit 30 also directly transmits with respect to radiator 5 except that transmitting in the air of configuration space B1.The heat that is delivered to radiator 5 is shed well by the air efficient of a plurality of fin 51 to second wind path 9 '.On the other hand, in the electric component 31, the easiest heating of coiler part 31A, the heat of this coiler part 31A transmits in the air of first wind path 9 '.
When first and second fan 8,8 ' work, the air of suction inlet 80,80 ' periphery is taken into by first and second fan 8,8 ', and these air are sent in wind path 9,9 ' along the direction of intersecting with first and second wind path 9,9 ' length direction from outlet 81 as wind.In this, extraneous air flows into to configuration space B2 from suction hole portion 20 together.
At this moment, with aforesaid embodiment similarly, be positioned at and leave the inflow resistance that suction inlet 80,80 ' locational suction hole portion 20 become air, producing enough pressure differentials near the suction inlet 80,80 ' and between near the suction hole portion 20.Thus, become negative pressure in the configuration space B2.The air that contains dust that is drawn in the configuration space B2 from suction hole portion 20 is detained and flows simultaneously to each fan 8,8 ' suction inlet 80,80 ’ Minus speed, dust is removed fully therebetween, and first and second fan 8,8 ' can be taken into the amount air still less of dust.Therefore, suppress effectively from the dust of said fans 8,8 ' in wind enters into first and second wind path 9,9 '.
Be sent to wind in first wind path 9 from first fan 8 and be divided into two and flow and contact with electric component 31 simultaneously to the length direction both ends of this wind path 9.At this moment, because wind directly contacts with the coiler part 31A of electric component 31, therefore capture heat effectively from this coiler part 31A.In addition, the length direction both ends of wind direction first wind path 9 that blows out from first fan 8 are divided into two, flow in relatively shorter distance and discharge to the outside from the outlet 90 of both sides.Therefore, the resistance of the wind that flows in first wind path 9 reduces, and wind is promptly discharged from exporting 90.Thus, efficient is carried out the air cooling to electric component 31 well.
The wind that is sent in second wind path 9 ' from second fan 8 ' directly contacts with radiator 5, flows to the length direction both ends of this wind path 9 ' along fin 51.At this moment, because wind contacts well with a plurality of fin 51 efficient, therefore capture a large amount of heats from the surface of each fin 51.In addition, the length direction both ends of wind direction second wind path 9 ' that blows out from second fan 8 ' are divided into two, flow in relatively shorter distance and discharge to the outside from the outlet 90 ' of both sides.Therefore, the resistance of the wind that flows in second wind path 9 ' reduces, and wind is promptly discharged from exporting 90 '.Thus, efficient is carried out the air cooling to radiator 5 well, and well electronic unit 30 is cooled off via these radiator 5 efficient.
Above-mentioned first and second wind path 9,9 ' is divided into the upper and lower, the electric component 31 that therefore is positioned at the electronic unit 30 on upper strata and is positioned at lower floor under the situation of the influence that is not subjected to heat mutually by first and second fan 8,8 ' air cooling.Thus, can efficient carry out the air cooling to electronic unit 30 and electric component 31 well.
In addition, lean under the electric component 31 easier situations about uprising because of the heating temperature of lower floor at for example radiator 5 than the upper strata, first fan 8 as lower floor can adopt more intense fan of air blast wind-force or large-scale fan.That is, first and second fan 8,8 ' can adopt the different fan of cooling capacity.And then, under situations different on the actuation time of for example electronic unit 30 and electric component 31, correspondingly can make the moment of first and second fan 8,8 ' work different respectively.
In the supply unit A1 of present embodiment, second fan 8 ' on the length direction of first fan 8 on the length direction of first wind path 9 and the distance of electric component 31 or second wind path 9 ' and the distance of electronic unit 30 length more whole than above-mentioned wind path 9,9 ' is short, and electronic unit 30 and electric component 31 are configured in and the position closer with respect to each fan 8,8 '.Therefore, electronic unit 30 or electric component 31 can be in configurations freely to a certain extent on first and second wind path 9,9 ' F direction.
