The circumferential surface of the stator core is provided with radiating tubes; a centrifugal blower is fixed on the radiating tubes; the inner cavities of the radiating tubes are communicated with the inner cavity of the motor; the two ends of each radiating tube are provided with air inlets; and an air outlet of each radiating tube is disposed at the lower end of the centrifugal blower. The cooling device has the advantages of concise design, high radiating efficiency, small size and low operating noise.
Description
Technical field
The utility model relates to the motor device field, relates in particular to a kind of cooling device of voltage three-phase asynchronous motor.
Background technology
The huge radiator of existing voltage three-phase asynchronous motor is placed oneself in the midst of the top of motor.As the motor at YKK450, the interior space lining of radiator has been expired 343 radiating tubes, the heat energy that motor produces is expressed to the hot-air of motor cavity the inner chamber of radiator under the effect of internal fan, then get back to again motor cavity, absorb heat energy by the outer wall of radiating tube, the inner chamber of the radiating tube heat energy that cooling-air absorbs radiating tube that circulates under the effect of external fan for electric machine is taken away.Existing radiator volume is huge; The utilance of inside and outside fan is low, uses along circumference and calculates and only used 1/4th.The radiating efficiency of radiator is low.Because at internal fan, to the drag effects that is subject to radiating tube in radiator during the extruding hot-air, making the pressure inequality, the every heat energy inequality that pipe absorbs.
The utility model content
The purpose of this utility model is to provide a kind of cooling device of voltage three-phase asynchronous motor, can improve the radiating efficiency of radiating tube, reduces the volume of motor integral body.
For achieving the above object, the utility model adopts following technical scheme: a kind of cooling device of voltage three-phase asynchronous motor, comprise the internal fan and the stator core that are arranged on motor internal, the circumferential surface of described stator core arranges radiating tube, and the top of described radiating tube is fixedly installed centrifugal blower; The inner chamber of described radiating tube is to be communicated with setting with motor cavity, and the two ends of described radiating tube arrange respectively air inlet, and the air outlet of radiating tube is set in the lower end of centrifugal blower.
Described air inlet arranges opening straight up, and described opening is communicated with extraneous air.
Described radiating tube is disposed in an evenly spaced relation in the circumferential surface of stator core.
Described radiating tube is 55.
The utility model is by being arranged on the radiating tube of stator core circumference, and under the effect of internal fan, the thermal current of motor is by cavity and motor cavity circulation in radiating tube.The inner chamber of radiating tube has been expired in thermal current punching uniformly, the heat energy of the high efficiency absorption motor of wall energy in radiating tube.The outer wall of radiating tube two inspiration cooling-air under the effect of centrifugal blower is discharged heat energy by centre again; Improve the radiating efficiency of radiating tube, reduced the volume of motor integral body.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of cooling device of voltage three-phase asynchronous motor, comprise the internal fan 6 and the stator core 5 that are arranged on motor internal, and the circumference of stator core 5 arranges radiating tube 1, and the top of radiating tube 1 is fixedly installed centrifugal blower 2; The inner chamber of radiating tube 1 is to be communicated with setting with motor cavity 7, and the two ends of radiating tube 1 arrange air inlet 4, and the air outlet 3 of radiating tube 1 is set in the lower end of centrifugal blower 2.Two air inlets 4 all arrange opening straight up, and opening is communicated with extraneous air.Radiating tube 1 is disposed in an evenly spaced relation in the circumferential surface of stator core 5.Radiating tube 1 is 55.The power that centrifugal blower 2 adopts is 3KW.
The hear rate of the stator core 5 of motor accounts for 60% left and right of the whole loss of motor, so the radiating efficiency of stator core 5 is improved, and whole motor has just been obtained good radiating effect.The large I of the flow of centrifugal blower 2 and pressure is selected according to power and the heat radiation situation of motor.The radiating tube 1 of the utility model by being arranged on stator core 5 circumferential surfaces and the centrifugal blower 2 on radiating tube 1 top, make outer wall air inlet 4 inspiration cooling-airs by two ends under the effect of centrifugal blower of radiating tube 1 be discharged heat energy by centre air vent 3 again; Improve the radiating efficiency of radiating tube, and reduced the volume of motor integral body, reduced noise.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
