In addition, be provided with guiding element 12a, support member 19a, the 19b that 12b fixes on the next door, both sides of the left and right directions of the described rectangular hole portion 18 of the framework 2 of described DC-to-AC converter 1 to the left and right directions both sides of the upside fan guard 9a that is formed on described fan unit 8.
Be fixed in the framework 2 of control device for inverter 1 by the fan unit pressing plate 17 that will be contained in the fan unit 8 of described control device for inverter 1 by set screw 14, fan unit pressing plate 17 is pushed down downside fan guard 9b, and fan unit 8 is remained on the control device for inverter 1.
In the above-described configuration, pulling down described fan unit 8 from described control device for inverter 1 is following carrying out.
At first, fully unclamp set screw 14.Needn't pull down set screw 14 this moment.Carry out following configuration afterwards, shown in Fig. 6 (c), fan unit pressing plate 17 is slided to the right, under the state of fan unit pressing plate 17 and downside fan guard 9b butt, shown in Fig. 6 (d), make the 2nd big hole 16b of aperture in the keyhole hole 16 that is formed on the fan unit pressing plate 17 be in the position that overlaps with set screw 14.
Afterwards, after confirming that fan unit pressing plate 17, downside fan guard 9b and set screw 14 are not interrupted, hand is placed on the outstanding edge 9aa of the upside fan guard 9a that is formed at fan unit 8, goes out fan unit 8, then can pull down from control device for inverter 1 to the front layback.Install and then carry out with opposite step.
The fan unit 8 that is contained in DC-to-AC converter has above-mentioned formation, and has effect as described below, effect.
(1) owing to directly on fan guard 9, do not have a keyhole hole, so do not need to make weight fan unit 8 to slide during mounting or dismounting.Therefore, required very little the getting final product of power of mounting or dismounting.
(2),, can realize the miniaturization of control device for inverter 1 so do not need to guarantee the space of sliding because fan unit 8 is slided.
(3),, can carry out the mounting or dismounting operation of fan unit 8 at short notice effectively so set screw 14 can not drop and loses to control device for inverter 1 inside owing to do not pull down set screw 14 and just can not carry out the mounting or dismounting of fan unit 8.
In addition, the hole that is formed on the described fan unit pressing plate 17 is not only keyhole hole 16, even for example slotted hole or half hole etc., also can be by not unclamping set screw 14 with pulling down, described fan unit pressing plate 17 is slided, can realize the mounting or dismounting of described fan unit 8.
In addition, as shown in Figure 7, the part of described upside fan guard 9a forms flat guiding element 12a, 12b, by contacting with support member 19a, the 19b of the framework 2 of DC-to-AC converter 1 as fan unit 8 install, guiding element when pulling down, can install and remove operation easily effectively.
In addition, as shown in Figure 8, described flat guiding element 12a, 12b observe from the top and form the L font, by fixing support member 19a, the 19b of this guiding element 12a, 12b and described framework 2, form wind-tunnel 20 by both, can cool off effectively and dispose to such an extent that very near heater is a reactor 21.
In addition, when described DC-to-AC converter 1 is installed on plate etc., be top with fan unit 8, radiator 7 is installed for the form of back side portion.
In addition, in the above-described embodiments,, also can on upside fan guard 9a, lip part 13 be set though downside fan guard 9b is provided with lip part 13.
