Abstract
The invention relates to a large-power hub motor stator's thermal conductance heat-radiation cooling end cap. End-cap cooling fins are secured to an end portion of a heat-radiation end cap. Heat-conduction lubrication silicone grease and a seal are installed at the juncture of the inner surface of the heat-radiation end cap and a motor stator. As the heat-radiation end cap is rotational, the heat-radiation end cap must be separated from the static motor stator. Heat generated by the motor stator is transferred through the heat-conduction lubrication silicone grease to the end-cap cooling fins on the heat-radiation end cap to be dissipated. Thus, heat radiation of the motor stator is guaranteed.
Description
Technical field
The present invention is that the high-power wheel hub motor stator thermal conductance belonging in technique with the apparatus field goes out cooling end cap.
Background technology
Due to the stator of the high-power wheel hub motor being sealed, weak heat-dissipating, continuous power output is excessive, and caloric value is also large, very easily damages motor, therefore, must dispel the heat by heat-conducting mode.
Summary of the invention
The object of this invention is to provide high-power wheel hub motor stator thermal conductance and go out cooling end cap, realize the object of end cap heat radiation.
Its objective is that such realization, high-power wheel hub motor stator thermal conductance go out cooling end cap and be made up of heat radiation end cap, end cap fin, sealing, the lubricated silicone grease of heat conduction, motor stator, rotor, power output shaft; End at heat radiation end cap is fixed with end cap fin, at the heat radiation inner face of end cap and the junction of motor stator, the lubricated silicone grease of heat conduction and sealing is housed, and rotor and motor stator keep certain running clearance to install, and power output shaft is fixedly connected with rotor.
Because heat radiation end cap rotates, so must with static motor stator between separate, the heat that motor stator produces lubricates silicone grease by heat conduction and passes the end cap fin heat radiation that thermal conductance to radiating end is covered, gap between heat radiation end cap and motor stator is very little, centre adds again heat conduction to lubricate silicone grease, therefore, motor stator heat radiation obtains and ensures.
Accompanying drawing explanation
Concrete structure of the present invention is provided by following examples and accompanying drawing:
Fig. 1, be that the high-power wheel hub motor stator of the present invention thermal conductance goes out cooling end cover structure schematic diagram.
In Fig. 1,1, heat radiation end cap, 2, end cap fin, 3, sealing, 4, the lubricated silicone grease of heat conduction, 5, motor stator, 6, rotor, 7, power output shaft.
Embodiment
Describe below in conjunction with Fig. 1 the specific works situation that the present invention proposes in detail, in Fig. 1, be fixed with end cap fin 2 in the end of heat radiation end cap 1, at the heat radiation inner face of end cap 1 and the junction of motor stator 5, the lubricated silicone grease 4 of heat conduction and sealing 3 are housed, rotor 6 keeps certain running clearance to install with motor stator 5, and power output shaft 7 is fixedly connected with rotor 6.
Because heat radiation end cap 1 rotates, so must with static motor stator 5 between separate, the heat that motor stator 5 produces lubricates silicone grease 4 by heat conduction and conducts to the end cap fin 2 of heat radiation on end cap 1 and dispel the heat, gap between heat radiation end cap 1 and motor stator 5 is very little, centre adds again heat conduction to lubricate silicone grease 4, therefore, motor stator heat radiation obtains and ensures.
