The air vent portion 21 of the wind of mouth 90 blowout face portion 2C and back part 2D by being arranged on casing cover 2 promptly blows to outside
Go out.
It follows that the effect of above-mentioned supply unit A is described.
Supply unit A exports big electric current and the high voltage of welding in action, generates heat therewith multiple parts 3 and causes it
Temperature raises.The heat of each parts 3, in addition to transmission in the air to configuration space B1, directly transmits also relative to radiator 5.This
Time, owing to the heat conductivity compared with air of the raw-material metal as radiator 5 is big, the heat therefore produced at each parts 3
Transmit well to radiator 5 efficiency.
Radiator 5 is big with the surface area of air contact by multiple fin 51.Therefore, radiator 5 with heat quilt
In multiple fin 51 air in wind path 9, efficiency sheds well.
When fan 8 works, the air of suction inlet 80 periphery is taken into by fan 8, and these air are as the length on wind edge with wind path 9
The direction that degree direction intersects is sent in wind path 9 from outlet 81.Being accompanied by this, extraneous air is empty to configuration from suction hole portion 20
Between B2 flow into.
Now, as it is shown on figure 3, the suction hole portion 20 being positioned away from the position of suction inlet 80 becomes the inflow resistance of air
Power, near suction inlet 80 and near suction hole portion 20 between produce enough pressure differentials.Thus, become negative in configuration space B2
Pressure.The air containing dust being drawn in configuration space B2 from suction hole portion 20 flows while being detained to suction inlet 80 speed
Dynamic, dust is sufficiently removed therebetween, and fan 8 can be taken into the air that the amount of dust is less.Therefore, effectively suppress from fan 8
The dust in wind path 9 is entered together with wind.
The wind being sent in wind path 9 from fan 8 directly contacts with radiator 5, along fin 51 to the length side of wind path 9
Flow to both ends.Now, owing to wind contacts well with multiple fin 51 efficiency, therefore the surface from each fin 51 is taken by force
Take substantial amounts of heat.It addition, be divided into two from the length direction both ends of the wind direction wind path 9 of fan 8 blowout, short compare
Flow in Ju Li and discharge to outside from the outlet 90 of both sides.Therefore, in wind path 9, the resistance of the wind of flowing diminishes, promptly
From outlet 90, wind is discharged.Thus, radiator 5 efficiency air well is cooled down, and via this radiator 5 by parts 3 also
Efficiency cools down well.
Owing to fan 8 is positioned at the length direction pars intermedia of wind path 9, hence along the lucky position of multiple parts 3 of wind path 9 configuration
Periphery in this fan 8.That is, the distance with each parts 3 of the fan 8 on the length direction of wind path 9 and the length phase of wind path 9 entirety
Ratio is short, and each parts 3 are arranged in the position closer relative to fan 8.By the position relationship of such fan 8 and parts 3 also
Multiple parts 3 efficiency can be cooled down well.Therefore, there is no need to the heat generation characteristic according to parts 3 and determine the position of each parts 3
Put, it is possible to multiple parts 3 are the most freely configured.
Additionally, in above-mentioned supply unit A, in wind path 9, the resistance of the wind of flowing reduces, therefore, it is possible to realize fan 8
Miniaturization and lightweight, and then realize low noise and the low consumpting power of fan 8.
When the utilization of above-mentioned supply unit A, owing to a certain degree of dust enters in wind path 9 together with air, therefore
Following state is easily become: dust enters and be collected at the fin 51 of radiator 5 in wind path 9 after the use of long time
In gap etc..If using supply unit A in such a state, then the radiating effect of radiator 5 weakens, and even parts 3 do not have
It is sufficiently cooled, as a result of which it is, parts 3 are it may happen that hot injury.Therefore, during utilization, carry out using not shown jet gun
Blow away the such dedusting operation of the 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
For the state exposed, thereafter, the air ejiction opening of jet gun is sprayed towards inside from the outlet 90 of a side of such as wind path 9
Compressed air.Compressed air becomes the jet flow of the length direction along wind path 9, by strong for the dust being deposited between such as fin 51
Blow out to the outlet 90 of the opposing party to power.
It addition, the compressed-air actuated injection direction ejected from jet gun becomes the direction of the length direction along wind path 9,
Become the direction that the air blast direction with fan 8 intersects.Thus, the compressed air from jet gun becomes and is difficult to fan 8
Blade directly acts on the jet flow of blast.Therefore, when the dedusting operation employing jet gun, will not occur can be because of compressed-air actuated
Strong jet flow and make the situation of fan 8 high speed reverse rotation, do not exist and make the blade of this fan 8 and the damaged probability of swivel bearing.
And then, according to above-mentioned supply unit A, owing to suppression enters into the dust in wind path 9 from fan 8 together with wind, because of
This can extend to carry out the period till dedusting operation, improves efficiency of movement.
