Abstract
The utility model discloses a frequency changer relates to electron technical field, concretely relates to frequency changer heat radiation structure. Including the frequency changer body, install the fan case above the frequency changer body, be covered with a heat dissipation shell at frequency changer body and fan case outside, be connected with two heat dissipating barrel on the fan case, the heat dissipating barrel port sets up in heat dissipation shell outside, have the side door on the shell right side of dispelling the heat, heat dissipation shell rear side has the rear side louvre, and there are two preceding louvres heat dissipation shell front side, inside the casing of preceding louvre intercommunication frequency changer body. The utility model provides a current frequency changer have the problem that heat dispersion is not good.
Description
Technical field
The utility model relates to electronic technology field, is specifically related to radiating structure of frequency converter.
Background technology
Frequency converter (Variable-frequencyDrive, VFD) is application converter technique and microelectric technique, controls the electric control appliance of alternating current motor by changing machine operation supply frequency mode.Frequency converter is primarily of the composition such as rectification (AC-DC), filtering, inversion (direct current becomes interchange), brake unit, driver element, detecting unit microprocessing unit.Frequency converter close to the inner portion IGBT cut-off the voltage and the frequency that adjust out-put supply; there is provided the supply voltage required for it according to the actual needs of motor, so reach energy-conservation, the object of speed governing, in addition; frequency converter also has a lot of defencive functions, as overcurrent, overvoltage, overload protection etc.Along with improving constantly of industrial automatization, frequency converter have also been obtained application widely.
Existing frequency converter is generally installed on transformer, controller periphery, has the heat that other electrical equipment distributes around frequency converter, and frequency converter is operated in the environment of high temperature, and heat dispersion is bad.
Summary of the invention
The utility model provides frequency converter, and the utility model solves existing frequency converter and there is the bad problem of heat dispersion.
For solving the problem, the utility model adopts following technical scheme: frequency converter, comprise transducer body, above transducer body, fan case is installed, a radiation shell is covered with outside transducer body and fan case, fan case is connected with two heat-dissipating cylinders, heat-dissipating cylinder port is arranged at outside radiation shell; On the right side of radiation shell, have side door, have rear side louvre on rear side of radiation shell, have two front louvres on front side of radiation shell, front louvre is communicated with the enclosure interior of transducer body.
Advantage of the present utility model: the utility model is provided with radiation shell, separates transducer body and other electric component, and transducer body is had enough to meet the need enough heat-dissipating spaces.Radiation shell is provided with side door, rear side louvre, front louvre, good ventilation and heat can be realized.It is simple that the utility model has structure, the advantage of perfect heat-dissipating.
Accompanying drawing explanation
Fig. 1 is the utility model vertical view;
Fig. 2 is that the A-A of Fig. 1 analyses and observe rotation diagram.
Symbol description in figure: side door 1, radiation shell 2, rear side louvre 3, heat-dissipating cylinder 4, fan case 5, front louvre 6, transducer body 7.
Embodiment
By best embodiment, the utility model is described in detail below
.
As shown in Figure 1-2, frequency converter, comprises transducer body 7, transducer body 7 is provided with fan case 5 above, provided with fan in fan case 5, is covered with a radiation shell 2 outside transducer body 7 and fan case 5, and bottom surface and the front side of transducer body are fixed on radiation shell.Leave enough heat radiation air passing space in radiation shell 2, namely in radiation shell, left and right space width is 0.2-1 times of transducer body width.Fan case 5 is connected with two heat-dissipating cylinders 4, heat-dissipating cylinder 4 port is arranged at outside radiation shell 2; On the right side of radiation shell 2, have side door 1, have rear side louvre 3 on rear side of radiation shell 2, have two front louvres 6 on front side of radiation shell 2, front louvre 6 is communicated with the enclosure interior of transducer body 7.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of amplifying out or variation be still among protection range of the present utility model.
