Parts 3 are parts of operationally easily heating, the electronic unit being configuration example as the switch element of power circuit or diode, capacitor, and then are the such electric components of transformer or reactor.The through second partition 7A of above-mentioned parts 3 and be directly installed on radiator 5.Thus, the heat from each parts 3 is promptly transmitted to radiator 5.
Radiator 5 is radiating components of such as aluminum, has the base portion 50 be fixed on second partition 7A, extends and extend and the multiple fin 51 arranged along the vertical direction along F direction from base portion 50.Via screw (omit and illustrate) etc., parts 3 are directly installed in the local of the base portion 50 opposed with second partition 7A.Multiple fin 51 is the parts shed well to efficiency in air by the heat transmitted from base portion 50, and in order to improve radiating effect, surface area increases.This radiator 5 has and the size of second partition 7A with degree, has the lengthwise dimension of this degree of total length throughout wind path 9.In the present embodiment, radiator 5 also becomes cooling object.It should be noted that, the size of radiator also can be less than second partition 7A.
First dividing plate 6 is such as metal, the space in 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 degree size, in the above-below direction centre position horizontal arrangement of casing cover 2.The top wall in the space of the configuration space B1 of the first dividing plate 6 component parts 3, the configuration space B2 of fan 8 and these lower floors of wind path 9.It should be noted that, though be not particularly illustrated, be also provided with parts etc. in the space on upper strata.
Second partition 7A, 7B are such as metal, the space of the lower floor in device are divided into the configuration space B2 of the configuration space B1 of parts 3, fan 8, these spaces of wind path 9.Second partition 7A, 7B have and the F direction size of basal component 1 with degree, relative to basal component 1 and the first dividing plate 6 arranged perpendicular.Second partition 7A, 7B become configuration space B1, the configuration space B2 of fan 8, the vertical wall in these spaces of wind path 9 of parts 3.The side's of being provided with window 70 on second partition 7A, the party's window 70 exposes to configuration space B1 for making base portion 50 part for radiator 5, thus can at this part installing component 3.The party's window 70 is inaccessible by base portion 50.The opening 71 (with reference to Fig. 3) making fan 8 in the face of wind path 9 is provided with at the F direction pars intermedia of second partition 7B.
Fan 8 is by the tube-axial fan of such as multiple blade and motor integration, has suction inlet 80 and the outlet 81 of air in the axial both end sides of its motor.In this fan 8, outlet 81 as one man configures with the opening 71 of second partition 7B.That is, fan 8 is configured in the length direction pars intermedia of wind path 9, and outlet 81 is positioned at the position of the inner side in the face of wind path 9.Thus, the air blast direction of fan 8 becomes the direction intersected in horizontal plane with the length direction of wind path 9.Suction inlet 80 is positioned at configuration space B2, and the inner surface of side surface part 2A to separate the interval of regulation opposed.Thus, side surface part 2A becomes the fan opposed walls opposed with suction inlet 80.The front surface region of the suction inlet 80 in this side surface part 2A does not arrange suction hole portion 20.That is, suction inlet 80 leaves to a certain degree relative to the suction hole portion 20 by both ends, F direction being positioned at side surface part 2A.
Wind path 9 utilizes the wind from fan 8 to carry out Air flow to radiator 5, and is guided at these wind direction length direction both ends.This wind path 9 is a pair opposed in the direction of the width vertical wall with second partition 7A, 7B and then is that top wall opposed in the vertical direction and base wall surround with a part for a part for the first dividing plate 6 and basal component 1, is formed as cross section rectangular shape.The length direction both ends of wind path 9 become the outlet 90 that wind goes out.The wind sent in wind path 9 from fan 8 contacts with fin 51 and length direction both ends to wind path 9 are divided into two, captures a large amount of heats and blow out from outlet 90 simultaneously from this fin 51.These wind are promptly externally blown out by the air vent portion 21 of the face portion 2C and back part 2D that are arranged on casing cover 2.
Next, the effect of above-mentioned supply unit A is described.
Supply unit A exports big current and the high voltage of welding in action, generates heat and cause its temperature to raise thereupon multiple parts 3.The heat of each parts 3, except transmitting in the air to configuration space B1, also directly transmits relative to radiator 5.Now, because the thermal conductivity factor compared with air of the raw-material metal as radiator 5 is large, the heat therefore produced at each parts 3 transmits well to radiator 5 efficiency.
The surface area that radiator 5 is contacted with air by multiple fin 51 is large.Therefore, radiator 5 with heat shed well to efficiency in the air in wind path 9 by multiple fin 51.
When fan 8 works, the air of suction inlet 80 periphery is taken into by fan 8, and these air are sent in wind path 9 from outlet 81 with the direction that the length direction of wind path 9 intersects as wind edge.
Now, as shown in Figure 3, the air near the suction inlet 80 in configuration space B2 is sucked by fan 8, and extraneous air is sucked by configuration space B2 by the suction hole portion 20 be made up of multiple slit thereupon.This is because, the suction hole portion 20 be positioned on the position leaving suction inlet 80 becomes the inflow resistance of air, produce enough pressure differentials between near suction inlet 80 and near suction hole portion 20, in configuration space B2, become negative pressure.Thus, be drawn into the air containing dust in configuration space B2 from suction hole portion 20 to flowing while the suction inlet 80 Minus speed leaving configuration relative to suction hole portion 20 in the directionf, the major part of the dust in air to fall or because to contact with the internal face of configuration space B2 etc. easily and air separation because of gravity.Consequently, fan 8 can be taken into via configuration space B2 the air that effectively removes dust, and is sent in wind path 9 by these air.
The wind be sent in wind path 9 from fan 8 directly contacts with radiator 5, flows along fin 51 to the length direction both ends of wind path 9.Now, because wind contacts well with multiple fin 51 efficiency, therefore a large amount of heats is captured from the surface of each fin 51.In addition, be divided into two from the length direction both ends of the wind direction wind path 9 of fan 8 blowout, flow in the short distance compared and externally discharge from the outlet 90 of both sides.Therefore, in wind path 9, the resistance of the wind of flowing diminishes, and is promptly discharged by wind from outlet 90.Thus, by radiator 5 efficiency Air flow well, and via this radiator 5, parts 3 also efficiency are cooled well.
Because fan 8 is positioned at the length direction pars intermedia of wind path 9, the multiple parts 3 therefore configured along wind path 9 are positioned at the periphery of this fan 8 just.That is, the fan 8 on the length direction of wind path 9 is short compared with the length of wind path 9 entirety with the distance of each parts 3, and each parts 3 are configured in the position closer relative to fan 8.Also multiple parts 3 efficiency can be cooled well with the position relationship of parts 3 by such fan 8.Therefore, do not need the position determining each parts 3 according to the heat generation characteristic of parts 3, multiple parts 3 freely can be configured to a certain extent.
In above-mentioned wind path 9, the operate time of supply unit A is longer, and the amount of the dust entered together with the wind of fan 8 is more, easily becomes dust and is accumulated in state in gap of the fin 51 of radiator 5 etc.If use supply unit A in such a state, then the radiating effect of radiator 5 weakens, and even parts 3 do not have sufficiently cooled, and consequently, parts 3 fire damage may occur.Therefore, during utilization, carry out using not shown jet gun to blow away the such dedusting operation of dust in wind path 9 termly.
In the dedusting operation employing jet gun, pull down casing cover 2 from basal component 1 and make the outlet 90 of wind path 9 become the state exposed, thereafter, the air outlet of jet gun inwardly being sprayed compressed air from the outlet 90 of a side of such as wind path 9.Compressed air becomes the jet flow of the length direction along wind path 9, is strongly blown out to the outlet 90 of the opposing party by the dust be deposited in such as between fin 51.
In addition, the compressed-air actuated injection direction ejected from jet gun becomes the direction of the length direction along wind path 9, namely becomes the direction intersected with the air blast direction of fan 8.Thus, the compressed air from jet gun becomes not easily to the jet flow of the blade direct effect blast of fan 8.Therefore, when the dedusting operation employing jet gun, the situation making fan 8 high speed reverse rotation because of compressed-air actuated strong jet flow can not be there is, there is not the possibility of blade and the swivel bearing breakage making this fan 8.
And then, according to above-mentioned supply unit A, owing to suppressing the dust entered into together with wind from fan 8 in wind path 9, therefore, it is possible to extend to carry out dedusting operation till during, improve efficiency of movement.

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, except transmitting in the air to configuration space B1, also directly transmits relative to radiator 5.The heat being delivered to radiator 5 is shed well by the air efficiency of multiple fin 51 to the second wind path 9 '.On the other hand, in electric component 31, coiler part 31A the most easily generates heat, and the heat of this coiler part 31A transmits in the air of the first wind path 9 '.
During the work of first and second fan 8,8 ', 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 ' from outlet 81 with the direction that the length direction of first and second wind path 9,9 ' intersects as wind edge.Together in this, extraneous air flows into from suction hole portion 20 to configuration space B2.
Now, in the same manner as aforesaid embodiment, the air near the suction inlet 80,80 ' in configuration space B2 is sucked by first and second fan 8,8 ', and extraneous air is sucked by configuration space B2 by the suction hole portion 20 be made up of multiple slit thereupon.This is because, the suction hole portion 20 be positioned on the position leaving suction inlet 80,80 ' becomes the inflow resistance of air, produce enough pressure differentials between near suction inlet 80,80 ' and near suction hole portion 20, in configuration space B2, become negative pressure.Thus, be drawn into the air containing dust in configuration space B2 from suction hole portion 20 to suction inlet 80, the 80 ’ Minus speed leaving configuration relative to suction hole portion 20 in the directionf flows simultaneously, and the major part of the dust in air to fall or because to contact with the internal face of configuration space B2 etc. easily and air separation because of gravity.Consequently, first and second fan 8,8 ' can be taken into via configuration space B2 the air that effectively removes dust, and is sent in first and second wind path 9,9 ' by these air.
From the first fan 8 wind be sent in the first wind path 9 be divided into two and to this wind path 9 the flowing of length direction both ends and contact with electric component 31 simultaneously.Now, because wind directly contacts with the coiler part 31A of electric component 31, therefore effectively heat is captured from this coiler part 31A.In addition, be divided into two from the length direction both ends of wind direction first wind path 9 of the first fan 8 blowout, flow in shorter distance and externally discharge from the outlet 90 of both sides.Therefore, in the first wind path 9, the resistance of the wind of flowing reduces, and wind is promptly discharged from outlet 90.Thus, efficiency carries out Air flow to electric component 31 well.
The wind be sent in the second wind path 9 ' from the second fan 8 ' directly contacts with radiator 5, the length direction both ends flowing along fin 51 to this wind path 9 '.Now, because wind contacts well with multiple fin 51 efficiency, therefore a large amount of heats is captured from the surface of each fin 51.In addition, the length direction both ends of wind direction second wind path 9 ' blown out from the second fan 8 ' are divided into two, flowing in shorter distance and externally discharging from the outlet 90 ' of both sides.Therefore, in the second wind path 9 ', the resistance of the wind of flowing reduces, and wind is promptly discharged from outlet 90 '.Thus, efficiency carries out Air flow to radiator 5 well, and cools electronic unit 30 well via this radiator 5 efficiency.
First and second wind path 9,9 ' above-mentioned is divided into the upper and lower, the electronic unit 30 being therefore positioned at upper strata and the electric component 31 being positioned at lower floor when not mutually being subject to the affecting of heat by the air cooling of first and second fan 8,8 '.Thereby, it is possible to efficiency carries out Air flow to electronic unit 30 and electric component 31 well.
In addition, when such as easier than the electric component 31 of radiator 5 layer on the lower on upper strata because of heating, temperature uprises, as the first fan 8 of lower floor, fan or large-scale fan that air blast wind-force is stronger can be adopted.That is, first and second fan 8,8 ' can adopt the fan that cooling capacity is different.And then different on the actuation time of such as electronic unit 30 and electric component 31, the moment that first and second fan 8,8 ' correspondingly can be made to work is different respectively.
In the supply unit A1 of present embodiment, the length more overall than above-mentioned wind path 9,9 ' with the distance of electronic unit 30 with the second fan 8 ' in the distance of electric component 31 or the length direction of the second wind path 9 ' of the first fan 8 on the length direction of the first wind path 9 is short, electronic unit 30 and electric component 31 be configured in relative to each fan 8, the 8 ' closer position.Therefore, electronic unit 30 or electric component 31 freely can configure to a certain extent on the F direction along first and second wind path 9,9 '.
In the supply unit A1 of present embodiment, also carry out the dedusting operation employing jet gun.Now, the air ejiction opening of jet gun is inwardly sprayed compressed air from the outlet 90 of a such as side of the first wind path 9.Compressed air becomes the jet flow of the length direction along the first wind path 9, strongly blows away being attached to the outlet 90 of the dust on the coiler part 31A of electric component 31 to the opposing party.The compressed-air actuated injection direction ejected from jet gun becomes the direction of the length direction along the first wind path 9, namely becomes the direction intersected with the air blast direction of the first fan 8.Thus, when the dedusting operation employing jet gun, the situation making the first fan 8 high speed reverse rotation because of compressed-air actuated strong jet flow can not be there is, there is not the possibility of blade and the swivel bearing breakage making this fan 8.Similarly, in the second wind path 9 ', jet gun also can be used to carry out dedusting operation, now also there is not the possibility of blade and the swivel bearing breakage making the second fan 8 '.
