Abstract
The utility model discloses a ventilation device of an open-type variable frequency motor. The ventilation device comprises a motor body and cooling boxes. The two ends of the upper end surface of the motor body are provided with ventilating openings. The cooling boxes are connected with the motor body through the ventilating openings. A shutter is arranged on the side surface of the motor body. Centrifugal air machines are arranged on the cooling boxes. According to the utility model, the path of a cooling air course is shortened; the air quantity and the air pressure, which are originally obtained through large external fans, can be realized by virtue of relatively small fans; the overall loss is reduced; and the single small cooling box is small in size, compact in structure, and convenient to mount. The air guiding structures inside the cooling boxes are reasonable, and moreover, fans of the air machines are directly aligned to the ventilating openings of the motor so that the wind resistance is reduced; the cooling effect is greatly enhanced; and the overall material cost is lower than the cost of an original cooling device.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of ventilation unit of open type variable-frequency motor.
Background technology
The heating when work of open type variable-frequency motor can cause reduce useful life, and its main position that generates heat is the stator and rotor windings, but variable-frequency motor can't provide enough airflow pressures to be used for motor radiating when low frequency.Therefore make motor and surrounding air form the circulation of nature to guarantee effective heat radiation at the exterior cooling device of the outside meeting of open type adjustable frequency motor.At present general box electric machine is all installed a larger cooling device at the top, and at the top of cooling device 1 to 2 blower fan that adds is installed, and motor is forced heat radiation.Outside motor forces cooling blower to form wind path by a ventilator cowling and top, and cooling air enters motor internal by two ends and is discharged in the air by top blower fan extraction hot-air.The two ends air enters cooler and enters motor internal again, then enters cooler by motor internal and discharges, and the wind path path is longer, and particularly to large-size machine, and this structure need to add a larger cooler, and materials'use is more, and cost is relatively high.
The utility model content
The utility model provides a kind of simple and compact for structure in order to overcome the deficiencies in the prior art, and the materials'use amount is little, and utilizes motor body installation shutter to reduce the wind path path, the ventilation unit of the open type variable-frequency motor of good cooling results.
To achieve these goals, the utility model is by the following technical solutions: a kind of ventilation unit of open type variable-frequency motor, comprise motor body, and also comprise cooler bin, the two ends of the upper surface of described motor body are provided with ventilating opening, and described cooler bin is communicated with by ventilating opening and motor body; The side opening of described motor body is provided with shutter, and described cooler bin is provided with centrifugal blower.
As preferably, described cooler bin air inlet is equipped with annular wind deflector, is provided with arc wind waveguide plate in the described cooler bin, and described cooler bin, annular wind deflector and arc wind waveguide plate form drainage wind chamber.
As preferably, the end of described cooler bin is provided with seam, and the end of described centrifugal blower is connected with ring flange, and described seam and ring flange are bolted.
The beneficial effects of the utility model are: the utility model has shortened the path of cooling air duct, can utilize air quantity and the blast that just can reach former large external fan than small fan, reduced whole loss, and the volume of single little cooler bin is little, and compact conformation is convenient to install.The inner reasonably air guide structure of cooler bin, blower fan is directly aimed at the motor ventilation mouth in addition, reduces windage, and cooling effect is strengthened greatly, and whole material cost is lower than the cost of original cooling device.

Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, complete description.
A kind of ventilation unit of open type variable-frequency motor, as shown in the figure, comprise motor body 1, also comprise cooler bin 2, the two ends of the upper surface of described motor body 1 are provided with ventilating opening 7, described cooler bin 2 is bolted on directly over the motor main body 1 two ends ventilating opening 7, is communicated with by ventilating opening 7 and motor body 1; The two sides of described motor body 1 offer shutter 6, described cooler bin 2 is provided with centrifugal blower 3, the end of described cooler bin 2 is provided with seam 8, the end of described centrifugal blower 3 is connected with ring flange 9, described seam 8 and ring flange 9 are bolted, described cooler bin 2 ventilating openings are equipped with annular wind deflector 4, are welded with arc wind waveguide plate 5 in the described cooler bin, and described cooler bin 2, annular wind deflector 4 and arc wind waveguide plate 5 form drainage wind chamber 10.
Centrifugal blower 3 runnings of two cooler bins 2 at two ends, outside air is passed through wind deflector, and reduced windage by fan, arc wind waveguide plate 5 and also discharged downwards, directly blast inside from motor ventilation mouth 7, directly discharge from the both sides shutter 6 of motor, the utilance of cooling air has been improved in the path of having shortened cooling air, can more effectively reduce motor operation temperature rise, and the installation dimension of both sides cooler bin 2 has unanimously guaranteed interchangeability.
Obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all should belong to the scope of the utility model protection.
