Abstract
The utility model discloses a heat radiation fan of a computer CPU (Central Processing Unit). The heat radiation fan comprises a fan (1) and a heat radiation block (2), and is characterized in that the top planes of blades (11) of the fan (1) form a hemispherical plane; the middle parts of heat radiation fins (21) of the heat radiation block (2) are respectively provided with a concave spherical face adaptive to the fan blade. The heat radiation fan is rational in structure, good in heat radiation effect and long in service life.
Description
Technical field
The utility model relates to fan, specifically a kind of computer CPU radiation fan.
Background technique
The end face of existing each blade of computer CPU radiation fan is almost on a plane, and the end face of radiating fin is also smooth structure, this structure, and heat diffusion area is little, although the rotating speed of fan is fast, radiating effect is still not ideal.
Model utility content
The purpose of this utility model is just to provide the computer CPU radiation fan of a kind of rational in infrastructure, excellent in heat dissipation effect, long service life.
For achieving the above object, the utility model comprises fan and radiating block, and the end face of the flabellum of described fan is combined into hemisphere face, and the intermediate portion of the radiating fin of described radiating block is provided with the concave spherical surface adapting with flabellum.
The utility model is because the intermediate portion that has adopted the end face of the flabellum of fan to be combined into the radiating fin of hemisphere face and radiating block is provided with the structure of the concave spherical surface adapting with flabellum, greatly increased the heat diffusion area between electric fan and radiating fin, this structure, compare with radiation fan in the past, the in the situation that of same rotating speed, radiating effect significantly improves, therefore meeting under the prerequisite of radiating effect, can suitably reduce the rotating speed of fan, to extending the working life of fan.The utility model is rational in infrastructure, excellent in heat dissipation effect, long service life.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Referring to Fig. 1, the utility model comprises fan 1 and radiating block 2, and the end face of the flabellum 11 of described fan 1 is combined into hemisphere face, and the intermediate portion of the radiating fin 21 of described radiating block 2 is provided with the concave spherical surface adapting with flabellum.
Claims (1)
