Description
Technical field
This utility model is related to a kind of good automobile current generator of thermal diffusivity.
Background technology
Automobile current generator, including the housing being made up of drive end bearing bracket, rear end cap, stator, rotor, commutator, actuator etc.；Turn
Attached bag includes two pawl poles being oppositely arranged, is located at rotor windings and its skeleton, the armature spindle that pawl pole is surrounded in the cavity constituting,
Rotor windings in pawl pole after generator operation can produce amount of heat, and these heats must radiate out in time, not so can burn
Bad rotor windings make electromotor scrap, and traditional way is to connect heat conduction fan blade in the both sides of pawl pole, by heat conduction fan blade handle
Out, and heat conduction fan blade is when mounted, is set on armature spindle for heat spreader, during assembling and pawl pole installs unreliable and pawl pole
On heat can not conduct in time to heat conduction fan blade, make radiating slower.
Content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model be to provide a kind of heat conduction fan blade install reliable with
And the automobile current generator that heat conduction and heat radiation is good.
For achieving the above object, this utility model provides following technical scheme：A kind of good automobile current generator of thermal diffusivity,
Including the housing being made up of drive end bearing bracket, rear end cap, stator and rotor；Described rotor include two pawl poles being oppositely arranged,
Rotor windings in the cavity that pawl pole encirclement is constituted, skeleton and armature spindle, the end face of the pawl pole described in two sets respectively
Have heat conduction fan blade, described heat conduction fan blade be provided with annular section be square embedded projection and annular section be " V " type
Guiding projection, described pawl pole end face be provided with the annular slot matching with described embedded projection and with described guiding projection
The annular gathering sill matching, fills heat-conducting silicone grease between described pawl pole and heat conduction fan blade, is provided with described housing
Several louvres.
This utility model is further arranged to：Described louvre is distributed on the side face of described housing and in front and back two
End.
By adopting technique scheme, during installation, heat conduction fan blade passes through the annular on the guiding projection and pawl pole of " V " type
Gathering sill guiding abuts, and then the embedded projection on heat conduction fan blade embeds in the annular slot in pawl pole, makes pawl pole and heat conduction wind
Leaf quick-fit, reaches heat conduction fan blade and installs reliable technique effect, and pawl pole and the cooperation of heat conduction fan blade can be made reliable, and thermal conductive silicon
Fat can make the heat in pawl pole quickly conduct to heat conduction fan blade, make working rotor temperature will not rapid increase, during work, heat conduction
Fan blade rotates and drives heat quickly to distribute from housing side face and rear and front end, realizes the good technology effect of heat conduction and heat radiation
Really.
With reference to the accompanying drawings and detailed description this utility model is further described.
Brief description
Fig. 1 is the sectional view of this utility model specific embodiment；
Fig. 2 is the housing front view of this utility model specific embodiment；
Fig. 3 is the front view of housing bottom in this utility model specific embodiment.
Specific embodiment
Below by embodiment, this utility model is specifically described, is served only for this utility model is carried out further
Illustrate it is impossible to be interpreted as the restriction to this utility model protection domain.
As shown in Fig. 1 Fig. 3, the utility model discloses a kind of good automobile current generator of thermal diffusivity, including by drive end bearing bracket
11st, the housing 1 of rear end cap 12 composition, stator 2 and rotor 3；Rotor 3 includes two pawl poles being oppositely arranged 31, is located at pawl pole
Rotor windings 32 in 31 cavitys surrounding composition, skeleton 33 and armature spindle 33, the end face of two pawl poles 31 are respectively equipped with and lead
Hot blast leaf 4, it is convex that heat conduction fan blade 4 is provided with the guiding that annular section is square embedded projection 41 and annular section is " V " type
Block 42, pawl pole 31 end face is provided with the annular slot 311 that matched with embedded projection 41 and is matched with guiding projection 42
Annular gathering sill 312, fills heat-conducting silicone grease 5 between pawl pole 31 and heat conduction fan blade 4, is provided with several radiatings on housing 1
Hole 13.
Preferably, louvre 13 is distributed on the side face of housing 1 and rear and front end.
By adopting above-described embodiment, during installation, heat conduction fan blade 4 passes through the ring on the guiding projection 42 and pawl pole 31 of " V " type
Shape gathering sill 312 guiding abuts, and then the embedded projection 41 on heat conduction fan blade 4 embeds in the annular slot 311 in pawl pole 31, makes
Pawl pole 31 and heat conduction fan blade 4 quick-fit, reach heat conduction fan blade 4 and install reliable technique effect, can make pawl pole 31 and heat conduction wind
Leaf 4 coordinates reliability, and heat-conducting silicone grease 5 can make the heat in pawl pole 31 quickly conduct to heat conduction fan blade 4, so that rotor 3 is worked temperature
Degree will not rapid increase, during work, heat conduction fan blade 4 rotate drive heat quickly give out from housing 1 side face and rear and front end
Go, realize the good technique effect of heat conduction and heat radiation.
