Description

Technical Field

[0001] The utility model relates to the field of generators, in particular to a ventilation end cover for a diesel generator. Background Art

[0002] Diesel generators usually install end covers on the outside of the gears on their rotating shafts to protect the gears. During the long-term operation of the diesel generator, the gears on its rotating shaft are in a state of meshing transmission for a long time, which causes the temperature inside the end cover to be high. The end cover needs to be cooled. Traditional diesel generator end covers only have heat dissipation holes on them for passive heat dissipation. This form makes the heat dissipation effect poor and inconvenient, so it still needs to be improved. Utility Model Content

[0004] Preferably, the heat dissipation plate is provided with a plurality of ventilation slots, which are arranged in a long and thin strip structure, and each ventilation slot is arranged on the front side of each second heat dissipation fin.

[0005] Preferably, the first heat dissipation fins and the second heat dissipation fins are staggered.
