Description
Technical field
The utility model relates to motor radiating technical field, is a kind of electric machine radiator concretely.
Background technology
Motor is when carrying out power conversion, and some loss is transformed into heat, and motor must constantly be gone out dissipation of heat, and the normal work of guarantee motor and minimizing are to the damage of parts around.Prior art is to drive the hot-air of motor internal to circulate by being arranged on the fan of motor afterbody, thus distribute heat, its radiating mode is single, and efficiency is low.
Utility model content
In order to solve deficiency of the prior art, the utility model provides a kind of electric machine radiator simple in structure, reasonable in design, has strengthened the circulation of air of motor internal and the circulation of air on motor surface, has improved radiating efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of electric machine radiator, comprise motor main body and motor body interior rotation axis, be arranged on the fan of motor main body afterbody, motor body surfaces is provided with some fin, it is characterized in that: described rotation axis extends motor main body afterbody, the extension of rotation axis is provided with fan hub, fan hub is provided with some primary blades, and primary blades end is extended with auxiliary blade; Described motor main body afterbody outside is provided with a cover body by support.
Between described auxiliary blade and primary blades, there is the angle of 90 °-130 °.
Described cover body length is 5-8cm.
Described support one end is connected with motor main body, and the link position of support and motor main body is between adjacent fin, and the support other end is connected with cover body.
This device by the extension at rotation axis arrange one by fan hub, primary blades and auxiliary blade, formed add strong wind fan group, add strong wind fan group integral diameter and be slightly larger than motor main body, can stereoscopic ventilation, strengthen the circulation of air of motor internal, add strong wind fan group and can by the passage between cover body and motor main body, drive the circulation of air between fin simultaneously, motor body interior and outside are carried out to heat radiation work simultaneously, increased radiating efficiency.
The beneficial effects of the utility model: simple in structure, reasonable in design, do not need to increase any additional kinetic energy, mainly depend on the rotation axis of motor, environmental protection and energy saving; And total mainly concentrates on motor trailing space, compact conformation; More do not need to destroy the internal structure of motor, be applicable to any motor, highly versatile carries out heat radiation work to motor internal and outside simultaneously, and radiating efficiency is high, has extended the useful life of motor component.
