Add and have a great influence close to stator coil, its temperature rise to rectifier；But it does not have plastic safety cover, at the same do band pump motor when compared with
For convenience.External generator, assembling is relatively simple, and rectifier and doing over again for adjuster repair more convenient, the heat dissipation of rectifier
More preferably；But rectifier and adjuster need to assemble shield protection, the band more difficult implementation of pump motor.
In high-power generator, rectifier uses 12 pipe structures more；Built-in rectifier, negative plate are fitted in end cap
On, end cap helps to radiate, and positive plate is radiated using more toothings；External rectifier, existing structure are mostly rear fixed cover conducts
Negative plate or negative plate, which are fitted in rear fixed cover, to radiate, and positive plate is radiated using die casting harden structure.When stator coil is using flat
During line stator, rear fixed cover is because stator heat transfer reason temperature is higher, and rectifies are generated heat on rectifier, and temperature passes
Lead, distribute poor, reach the junction temperature of rectifier diode, so as to cause defective rectifier.

Positive plate and conductive negative plate fixation rectifier diode, busbar stent connecting stator congruence stream, cathode output screw are externally defeated
Go out electric current, fixed cover support rim supports fixed rectifier, plastic safety cover protection rectifier and adjustment generator after generator
Air passage.It is characterized in that：Intermediate supports insulating support replaces insulating bushing insulation positive conductive electrode plate and conductive negative plate, in conduction
Die casting has B+ screw holes on positive plate；With six rectifier diode mounting holes.Conductive negative plate is below rectifier, with generator
Fixed cover support rim connection afterwards is fixed, and plastic safety cover lower edge is flushed with conductive negative plate top edge；During generator operation,
Positive conductive electrode plate is radiated by the inner side axial ducts and outside axial ducts inlet air of positive plastic safety cover, and conductive negative plate is just
By the distinguished and admirable heat dissipation of positive conductive electrode plate, conductive anode back passes through fixed after conductive negative plate and generator for face and inner side edge
The radial direction V-arrangement air duct radiation that capping is formed.Conductive negative plate is not bonded heat dissipation with fixed cover after motor, and the back side is equipped with radiation tooth.
Exterior on conductive negative plate that three rectifier diodes are housed, inside is equipped with three rectifier diodes, and spacing is relatively uniform, surrounding
Equipped with radiation tooth.
The conduction negative plate backside heat tooth is in emitting shape V-arrangement, in the case where not influencing product installation and packaging technology, is formed
V-arrangement air passage.
The conduction negative plate front and inner side are radiated by axial wind.
The inner side air passage of the conduction negative plate is corresponding with the inner side axial ducts of plastic safety cover.
