Description
Technical field
The utility model belongs to converter technology field, and in particular to a kind of shell mechanism of frequency converter.
Background technology
Frequency converter is to apply converter technique and microelectric technique, is handed over by changing motor working power Frequency Patterns to control
The electric control appliance of galvanic electricity motivation.
Frequency converter is mainly by rectification（AC to DC）, filtering, inversion（Direct current becomes exchange）, brake unit, driving unit,
The compositions such as detection unit microprocessing unit.IGBT cut-offs to adjust the voltage and frequency of out-put supply, root frequency converter close to the inner portion
Its required supply voltage is provided according to the actual needs of motor, and then achievees the purpose that energy saving, speed governing, in addition, frequency converter
Also many defencive functions, such as overcurrent, overvoltage, overload protection.With the continuous improvement of industrial automatization, frequency conversion
Device has also obtained very extensive application.
Common most of shell of frequency converter body on the market, structure setting is unreasonable, and assembly is inconvenient.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of shell mechanism of frequency converter, structure setting is reasonable, assembly
It is convenient.
Its technical solution is such：A kind of hermetically sealed shell structure of frequency converter, including bottom plate and case, feature exist
In the both sides of the bottom plate are respectively equipped with laterally attached plate, and the laterally attached plate is equipped with mounting hole, the side wall of the case
On be correspondingly provided with mounting hole, bolt is each passed through the mounting hole and is fixedly connected with the laterally attached plate with the case, institute
The front side for stating case is equipped with forceful electric power terminals sub-aperture and signal wire terminal hole, and fan mounting holes are additionally provided on front side of the case,
Fan is mounted in the fan mounting holes, and the rear side of the case is equipped with cooling vent, and the upper end of the case, which is equipped with, to be seen
Cha Kou.
Further, the bottom plate is equipped with frequency converter mounting hole.
Further, the bottom plate is equipped with radiator fixed block.
Frequency converter is mounted on bottom plate when use, case is covered on change by the shell mechanism of the frequency converter of the utility model
After on frequency device, bottom plate is fixedly connected with case by bolt, it is easy to assembly quick, it is dried frequency converter and is radiated by fan,
Heat is discharged from cooling vent, and the air duct radiation effect of fan and cooling vent composition is good.

Fig. 2 is the backsight structural representation of the case of the utility model.
Specific implementation mode
See Fig. 1, Fig. 2, a kind of shell mechanism of frequency converter of the utility model, including bottom plate 1 and case 2, the two of bottom plate 1
Side is respectively equipped with laterally attached plate 3, and laterally attached plate 3 is equipped with mounting hole 4, mounting hole 4 is correspondingly provided on the side wall of case 2,
Bolt is each passed through mounting hole 4 and is fixedly connected with laterally attached plate 3 with case 2, and the front side of case 2 is equipped with forceful electric power terminals sub-aperture
With signal wire terminal hole 5, fan mounting holes 6 are additionally provided on front side of case, fan is mounted in fan mounting holes 6, after case 2
Side is equipped with cooling vent 7, and the upper end of case 2 is equipped with observation panel 8, and bottom plate 1 is equipped with frequency converter mounting hole 9, and bottom plate 1 is equipped with
Radiator mounting hole 10.
The hermetically sealed shell structure of the frequency converter of the utility model, side plate are matched with aluminium heat sink by dovetail groove orifice inserting
It closes, is achieved a fixed connection by bolt and mounting hole cooperation between side plate and foreboard and back plate, aluminium heat sink, side plate, foreboard
And the shell structure sealing effect that back plate is constituted is good, the heat that frequency converter work generates is exported by aluminium heat sink, and is passed through
Fan blows radiating fin heat dissipation, and radiating efficiency is good.
Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model also has
Various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The requires of the utility model
Protection domain is defined by the appending claims and its equivalent thereof.
