Abstract
The utility model discloses a radiating structure of a motor stator. An assembling groove is formed on the inner wall surface of a stator; a ring-shaped radiating ring is embedded in the assembling groove; a plurality of ventilation holes are formed on an end surface between the central hole and outer wall surface of the radiating ring; a part between each two ventilation holes adopts a radiating fin; and a plurality of radiating grooves are formed on the outer wall surface of the radiating ring at intervals. The utility model has the advantage of good heat radiation of the motor stator.
Description
Technical field
The utility model relates to the motor stator technical field, is specifically related to a kind of radiator structure of motor stator.
Background technology
The prior art small generator often adopts permanent magnet as magnetic field sources, reduces required iron core of excitation and coil with this, has reduced the volume and weight of generator greatly.Owing to reduced required iron core and the coil of excitation, the minitype permanent magnetism generator often is designed to flat structure, and promptly the axial dimension of generator is little many than radial dimension.The permanent magnet generator of this flat structure is for the excitation-type generator, and structure is comparatively simple, assembles more or less freely.In addition, for reducing the generator volume as far as possible, the stator of permanent magnet generator and rotor all design very compactly.But, when reducing the generator volume, certainly will cause generator heat radiation difficulty.Prior art adopts modes such as increasing generator unit stator and rotor size usually, increases the radiating efficiency of generator.Obviously, increase generator unit stator and rotor size and again the so-called compact structure of permanent magnet generator is brought adverse influence.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model provides a kind of radiator structure that helps the motor stator that motor stator dispels the heat.
The technical scheme that realizes the utility model purpose is as follows:
The radiator structure of motor stator, comprise stator, the internal face of described stator is provided with fitting recess, the heat dissipating ring of an annular is embedded in this fitting recess, be arranged at intervals with some ventilation holes on the centre bore of heat dissipating ring and the end face between the outside wall surface, part between the ventilation hole is a fin in twos, and some radiating grooves are set on the outside wall surface of described heat dissipating ring at interval.
Described fin is corrugated fin.
Described fin is for being the fin of " V " font.
Adopted such scheme, the internal face of described stator is provided with cannelure, and the heat dissipating ring of an annular is embedded in this cannelure, can reduce heat dissipating ring like this and take space on the stator, is beneficial to make stator keep original volume.Be arranged at intervals with some ventilation holes on the centre bore of heat dissipating ring and the end face between the outside wall surface, part between the ventilation hole is a fin in twos, the heat transferred that stator sends is on heat dissipating ring and fin, out-of-date as wind from passing through aperture, by wind the heat on heat dissipating ring and the fin is taken away, therefore, help making heat in time to be distributed.Some radiating grooves are set on the outside wall surface of described heat dissipating ring at interval.By radiating groove, the heat radiation that increases heat dissipating ring is beneficial to the heat that makes on the stator and is dispersed on the heat dissipating ring fast long-pending.
Described fin is corrugated fin.Described fin is for being the fin of " V " font.The fin of these two kinds of shapes all helps to increase area of dissipation, is beneficial to accelerate heat radiation.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is the structural representation of heat dissipating ring;
In the accompanying drawing, 1 is stator, and 2 is heat dissipating ring, and 3 is ventilation hole, and 4 is fin.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See figures.1.and.2, the radiator structure of motor stator of the present utility model, the internal face of stator 1 is provided with fitting recess, the heat dissipating ring 2 of an annular is embedded in this fitting recess, be arranged at intervals with some ventilation holes 3 on the centre bore of heat dissipating ring and the end face between the outside wall surface, part between the ventilation hole is a fin 4 in twos, and fin is corrugated fin; Perhaps fin is for being provided with some radiating grooves at interval on fin (according to Fig. 2) wall that is " V " font.
