Further improvement of the utility model is, the spacing of the radiating fin of air side is less than or equal to safety size, and the spacing of the radiating fin of inlet air side is greater than safety size.
Further improvement of the utility model is, the end of the radiating fin of air side is L-shaped.
Further improvement of the utility model is, the end of the radiating fin of air side forms convex closure.
Further improvement of the utility model is, described bending part comprises the cover plate of the end being fastened on radiating fin, is less than the spacing of the radiating fin of inlet air side with the spacing of the radiating fin making air side.
Further improvement of the utility model is, in air side, the end engaging of at least part of radiating fin has cover plate, and the end of the radiating fin of remainder is exposed.
Further improvement of the utility model is, arranges a monoblock type cover plate, described cover plate has multiple cover plate in air side, and described cover plate coordinates the end being installed at least part of radiating fin.
Further improvement of the utility model is, in air side, described radiating fin is at least divided into two layer regions in short transverse, wherein, described radiating fin in described region towards a direction bending, towards other direction bending in another described region.
Further improvement of the utility model is, in inlet air side, the spacing of described radiating fin is 1.5mm.
According to another aspect of the present utility model, provide a kind of notebook computer, it has wind-cooling heat dissipating unit as above.
Owing to have employed above technical scheme, the air output of fan can be increased under identical fans rotating speed, make heat radiation module can heat radiation performance, safety requirement can be met again, improve heat exchange efficiency and materials'use quantity is reduced.
