Cheng Shang.
Further, the left side cooling fin and right side cooling fin, left side circuit board and right-hand circuit board are respectively left and right
It is symmetrical fan-shaped.
Further, between the left side circuit board, left side cooling fin and cathode rear shell and right-hand circuit board, right side dissipate
It is fixed respectively by fixing bolt, the insulating sleeve being sleeved on fixing bolt between backing and cathode rear shell.
The beneficial effects of the utility model are:
1, split left and right structure is respectively adopted in circuit board and positive pole radiating fin, and 6 pairs or 8 pairs of diodes are divided into two groups of difference
It is mounted on left and right side cooling fin, it, can directly more when left or right side diode is bad in production test process
Change the rectification axle assembly of respective side, to reduce production loss, while can prevent because overall structure it is excessive caused by circuit board and dissipate
Backing deformation.
2, circuit board is moved to above left and right side cooling fin by position between positive and negative cooling fin, makes the equal court of diode lead
Upwards, without overturning product in pinpoint welding procedure, circuit connection is can be completed in a spot welding, and more convenient operation improves production
Efficiency.
3, original product is changed to 6 pairs or 8 pairs of diodes using 3 pairs of diodes, reduces the rated power of each pair of diode,
Heat dissipation effect is improved, the service life of diode is extended.
