Description
Technical field
The utility model belongs to hub technology field, particularly relates to wheel hub motor radiator structure.
Background technology
At present, the heat dissipating method of the Wheel hub motor external rotor of market is single, except the improvement of heat sink material, mostly all still adopts on motor housing, designs a lot of wing fin, increase the contact area of motor housing and air.This design shortcoming shows as: on the one hand, and it can not make full use of the confined space of wheel hub according to boss shape; On the other hand, this original configuration design could not utilize the turning effort of motor self external rotor, and radiating efficiency is not high.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of Wheel hub motor external rotor air-cooled heat dissipation structure, improves radiating efficiency, solves a heat radiation difficult problem for wheel hub motor.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: Wheel hub motor external rotor air-cooled heat dissipation structure, comprise wheel hub motor wheel hub and be located at external rotor and the internal stator of wheel hub motor wheel hub inside, described internal stator center is provided with hub bearing, bobbin walked by the motor that described hub bearing center is provided with hollow, described external rotor is located at internal stator outer circumferential sides, described external rotor and wheel hub motor wheel hub are fixed, the end face of described wheel hub motor wheel hub is provided with several air ports, the excircle of described external rotor is provided with some fin and rotor blade, described external rotor, fin and rotor blade are metal and make.
Preferably, described fin and rotor blade are arranged side by side along outer roller axial.
Preferably, described rotor blade is obliquely installed, and the width of described fin is with rotor blade angle of inclination graded.
Preferably, described air port is sector structure, and several air ports described are evenly arranged around wheel hub motor hub centre.
Preferably, described external rotor is connected by bolt and wheel hub motor wheel hub.
The utility model makes full use of the confined space, the boss shape size characteristics of standard wheel hub, the end face of wheel hub motor wheel hub is provided with several air ports, the excircle of external rotor is provided with some fin and rotor blade, make because motor outer rotor, fin and rotor blade are heat dissipation metal material, there is good heat conductivility, the temperature of motor internal can be passed on fin and thinner rotor blade dispel the heat, increase the contact area with air.
In addition, when motor rotates (i.e. automobile traveling), under the rotation wind-guiding effect of rotor blade, make the air of vehicle outer side (i.e. lateral wheel) through wheel hub disc air port, blow to fin, thus the heat taken away on fin and rotor blade, make the air-cooled rear air relative wheel containing higher temperature move towards axle side along motor and blow to bottom of car, this wind-cooling heat dissipating is simultaneously synchronous with motor rotation, and then reduce motor outer rotor temperature fast, and then reduce the permanent-magnet steel temperature inside rotor.
To sum up, when the utility model utilizes wheel hub motor to rotate, the rotation feature of external rotor realizes dispelling the heat to the continuous and effective of hub motor for electric automobile.In addition, structure is simple, use safety, economy; Highly versatile.Do not need to increase other cooling devices or cooling device; Do not need extra energy supply.
