Abstract
The utility model relates to a novel motor heat radiation structure comprising a motor cover, a fan-contained motor cover, and a stator assembly. A lead hole is arranged in the outer surface of the motor cover; and the motor cover is connected with the fan-contained motor cover by the stator assembly. A fan mechanism is arranged at the outer wall surface of the fan-contained motor cover by an inclined way; and the lower end surface of the fan mechanism is connected with the fan-contained motor cover, wherein the lower end surface of the fan mechanism is protruded outwardly. The provided motor heat radiation structure has the following beneficial effects: the traditional complicated structure with the externally configured fan is improved into a built-in fan structure of the motor cover; and because of the position change, the good heat radiation effect is realized; the thermal protection-based automatic tripping caused by long-term usage can be prevented; and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to motor radiating technology, relates in particular to a kind of New-type electric machine radiator structure.
Background technology
Motor, when carrying out power conversion, always has sub-fraction loss to be transformed into heat, and it must constantly be gone out dissipation of heat, and the normal work of guarantee motor and minimizing are to the damage of parts around.The type of cooling of conventional motors has two kinds: freely circulate and casing surface cool.First, the mode freely circulating, absorbs heat in the time of need to be by the contacting of medium and motor and dispels the heat, and limited by electric machine structure, complex structure, and the space needing is larger; Secondly, existing casing surface cool mode, radiating efficiency is low, conventionally can not meet the demand of motor radiating.Also have a lot of senior motor radiating structures, heat in rotor and stator is directly distributed to motor outside by heat pipe, although this structure has the advantage of compact conformation miniaturization in the situation that meeting radiating effect, but its structure can be destroyed the internal structure of motor unavoidably, thereby affecting the working effect of motor, versatility is poor.
Existing radiator fan roughly comprises a fan frame, a driver element and an impeller, this driver element can drive this impeller spinning movement, make this impeller can introduce from this air intake vent the air-flow in extraneous space, and can in this air flow collection, via this air outlet, be disposed to the heat source position producing when an electronic product operates, the temperature while operating to reduce this electronic product.But in sum, above radiating mode is mostly pore heat radiation and external fan structure, long between in use after, the temperature of motor is high, may cause the automatic stop jumping of heat protection.Therefore,, for above aspect, need to reasonably improve prior art.
Utility model content
For above defect, the utility model provides a kind of good heat dissipation effect, environmental protection and energy saving, highly versatile, can improve the motor New-type electric machine radiator structure in useful life, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A New-type electric machine radiator structure, comprises motor cover, band fan electromotor lid, stator module, and described motor cover outer surface is set up a fairlead, and this motor cover is joined by stator module and band fan electromotor lid; Meanwhile, described band fan electromotor cover outer wall face tilt arranges fan, and fan lower surface wherein joins with band fan electromotor lid, and this fan lower end is outwardly.
Correspondingly, the inner rotor assembly of installing of described stator module, described rotor assembly central rotating shaft bearings at both ends is individually fixed in motor cover bottom, band fan electromotor lid bottom, and being positioned at rotor assembly bearing outer end cover has adjusting washer (disk).
Between rotor assembly bearing outer end and motor cover bottom, set up a wavy spring packing ring, between motor cover, stator module and band fan electromotor lid, be bolted.
The beneficial effect of New-type electric machine radiator structure described in the utility model is: by being the built-in fans structure that motor cover carries by the loaded down with trivial details architecture advances of traditional external another air distribution fan; the change of this position relationship, has good heat dissipation effect, long-time use is difficult for causing the automatic stop jumping of heat protection, can improves the advantages such as motor useful life.
