Support 48 is fixed on using fastening members such as screws.
By driving cooling fan 28, as indicated by arrows 92, the air of the inside of pipeline 41 is forcibly from flow export 46
Outflow.Moreover, extraneous gas is flowed into from inflow entrance 45.Because motor drive includes cooling fan 28, therefore, it is possible to strong
The flowing of air is produced in the inside of pipeline 41 to property processed.As a result, being capable of effectively cooling heat radiator portion 25.
In addition, in the case where motor drive includes cooling fan 28, can arbitrarily set motor driving
The direction of device.In the example shown in Fig. 9, the bearing of trend of pipeline 41 is parallel with the vertical shown in arrow 91.However,
2nd motor drive 2 can be installed on arbitrary direction.For example, the 2nd motor drive 2 can also be with pipeline 41
Bearing of trend and the mode of horizontal direction parallel be fixed on wall portion 11.In addition, in order to be promoted using the effect of the convection current of air
The flowing of air, the preferred disposition of flow export 46 is in the position more upper than inflow entrance 45.
The top view of the 2nd motor drive of present embodiment is represented in Figure 10.Cooling fan 28 is accommodated in pipeline
The inside of 41 main part 42.The width A of cooling fan 28 is less than the empty width B of the inside of main part 42.Cooling
The width A of fan 28 is not influenceed by the size of the opening portion 13 of wall portion 11.Therefore, it is possible to increase the width A of cooling fan 28.
That is, larger cooling fan 28 can be configured.
The approximate three-dimensional map of the motor drive of the 2nd comparative example is represented in Figure 11.The 2nd comparative example is represented in Figure 12
The outline partial sectional view of motor drive.Reference picture 11 and Figure 12, the motor drive of the 2nd comparative example are included admittedly
Due to the pipeline 73 and cooling fan 72 of tabular component 71.Heat transfer plate 75 is fixed with tabular component 71.It is configured at printing electricity
