Description
Technical field
The utility model relates to computer peripheral, is specifically related to a kind of radiation fan.
Background technique
Generally all there is the irrational situation of design in the cpu fan of existing computer in the market, cannot regulate fan turns frequency as required, simultaneously poor radiation.
Model utility content
For solving the problem, the utility model provides a kind of radiation fan, can select frequency of dispelling the heat as required, simultaneously good heat dissipation effect.
For achieving the above object, the technological scheme that the utility model is taked is:
A kind of radiation fan, comprise four installing taches that fan body and fan body upper bottom surface are provided with, described fan body is provided with the first radiation fan, the second radiation fan, described first radiation fan and the second radiation fan are all enclosed with heat-dissipating casing outward, described two heat-dissipating casings are connected by electric expansion bar, described heat-dissipating casing bottom is provided with and is connected with annulus by support, described electric expansion bar is connected with described annulus by screw thread, is provided with the cooling ring that a circle is surrounded by radiating fin outside described heat-dissipating casing.
As preferably, described electric expansion bar two ends are equipped with screw thread.
As preferably, described first radiation fan and the second radiation fan are all connected with motor by rotating shaft.
As preferably, described motor is fixed on described heat-dissipating casing.
The utility model passes through the design of the first fan and the second fan, the air flowing in cabinet can be strengthened, improve heat dispersion, the rotational frequency of the first fan and the second fan can be selected simultaneously as required, and the distance between the first fan and the second fan.
