Description
Technical field
The utility model relates to technical field of motors, is specifically related to a kind of brushless excitation generator rectifying disc.
Background technology
In known technology, the alternating current that armature of exciter produces is converted to direct current supply generator rotor through rectifying disc and carries out excitation by brushless excitation generator, rectifying disc rectifier diode is heat generating components, for solving rectifying disc rectifier diode heat dissipation problem, usual employing two kinds of structures: a kind of for rectifying disc be double disk structure, two disk bodies, for install back-to-back, install an aerofoil fan additional between amphidisc, rotated the cooling realizing rectifying disc by aerofoil fan; Another kind is simple disc structure, and rectifier diode is all arranged on disk body side, and disk body opposite side processes little flabellum, carries fan page rotate the cooling realizing rectifying disc by disk body; These two kinds of structures have following problem usually: double disk structure is due to aerofoil fan, comparatively Wind Volume can be produced, therefore rectifier diode can choose larger capacity specification, thus reduce rectifier diode usage quantity, but double disk structure takes up room greatly, stock utilization is low, and needs rectifying disc to remove the rectifier diode could changed on opposite side disk body when rectifier diode fault, opens and inspect difficulty excessive; Although and rectifier diode is arranged in side by simple disc structure, compact conformation, take up room little, the double disk structure solved takes up room greatly, opens and inspect the excessive problem of difficulty, but the fan carried due to simple disc structure is too little, the deficiency in draught of generation, thus the capacity limiting rectifier diode, the usage quantity of rectifier diode comparatively double disk structure adds one times, make disk body assembly difficulty excessive, between rectifier diode, gap is too small, and radiating effect is undesirable.
Utility model content
The purpose of this utility model is to provide that a kind of compact conformation, stock utilization are high, the brushless excitation generator rectifying disc of good heat dissipation effect.
For achieving the above object, the technical solution adopted in the utility model is, a kind of brushless excitation generator rectifying disc, comprise disk body and several rectifier diodes, rectifier diode is along the circumferential direction arranged on the inwall of disk body uniformly, inwardly be disposed with external heat sink, Inner heat sink along disk body radial direction, rectifier diode is between external heat sink, Inner heat sink; Described external heat sink is circular arc column, and two end faces of circular arc post are respectively arranged with flabellum, fin, and the side end face being provided with fin, near rectifier diode, is provided with a side end face of flabellum near disk body.
Described Inner heat sink comprises radiating block, and the circumference of radiating block is provided with radiating fin.
External heat sink, Inner heat sink are made by aluminium alloy.
The beneficial effect that the utility model produces is, flabellum when rectifying disc rotates on external heat sink can provide enough air quantity, and external heat sink is made up of aluminium alloy, there is good capacity of heat transmission, enhance the radiating effect of rectifier diode, thus can select jumbo diode, decrease diode usage quantity, make interval between diode enough large, draught area is enough large; Avoid that the usage quantity of rectifier diode in simple disc structure is more, disk body assembly difficulty is excessive, gap is too small between rectifier diode, the problem that radiating effect is undesirable; Inner heat sink processes fin, further increases the area of dissipation of diode.And the utility model solves the problem that double disk structure takes up room greatly, stock utilization is low, has the advantage of single double disk structure concurrently.

Embodiment
Embodiment 1
As Figure 1-5, a kind of brushless excitation generator rectifying disc, comprise disk body 1 and 6 rectifier diodes 3, rectifier diode 3 is along the circumferential direction arranged on the inwall of disk body 1 uniformly, inwardly be disposed with external heat sink 2, Inner heat sink 4 along disk body 1 radial direction, rectifier diode 3 is between external heat sink 2, Inner heat sink 4; Described external heat sink 2 is circular arc column, and two end faces of circular arc post are respectively arranged with flabellum 202, fin 201, and the side end face being provided with fin 201, near rectifier diode 3, is provided with a side end face of flabellum 202 near disk body 1.
Described Inner heat sink 4 comprises radiating block 401, and the circumference of radiating block 401 is provided with radiating fin 402.
External heat sink 2, Inner heat sink 4 are made by aluminium alloy.
Flabellum 202 when brushless excitation generator rectifying disc rotates on external heat sink 2 can provide enough air quantity, and external heat sink 2 is made up of aluminium alloy, there is good capacity of heat transmission, enhance the radiating effect of rectifier diode 3, thus can select jumbo diode.
