The heat dissipation module plays an important role in heat dissipation of electronic products at the present stage, the heat dissipation module in the market generally comprises fans, especially for electronic products with high heat dissipation requirements, when a plurality of fans are needed, however, the heat dissipation module can be selected to be used as the same fan to match, the rotating directions of the fan blades of the same fan are always the same, the directions of generated air flows are also consistent, a blind area gap can exist between the adjacent fans, because the rotating directions of the fan blades of the two adjacent fans are the same, the directions of the air flows generated by the two adjacent fans are opposite in the blind area gap, the two air flows can collide to form turbulent flow, sound noise is generated, the mute effect is influenced, and the market competitiveness of the heat dissipation module is not favorably improved.
In view of the above, the present inventors propose the following.
The utility model has the following contents:
an object of the utility model is to overcome prior art's is not enough, provide a heat dissipation module of making an uproar falls in fan just reversing.
In order to solve the technical problem, the utility model discloses a following technical scheme: this fan just reverses and falls heat dissipation module of making an uproar includes: the fan comprises a shell and at least two fans arranged on the shell, a blind area gap is formed between every two adjacent fans, one fan in the two adjacent fans is a forward rotating fan, the other fan is a reverse rotating fan, and the direction of airflow generated by the forward rotating fan when flowing through the blind area gap is the same as the direction of airflow generated by the reverse rotating fan when flowing through the blind area gap.
Further, in the above technical solution, a heat dissipation fin assembly is disposed in the housing, a hole location for mounting the fan is disposed on the housing, and the fan is disposed at the hole location and contacts with an end surface of the heat dissipation fin assembly.
Further, in the above technical solution, a plurality of heat conducting copper pipes are inserted into the heat dissipation fin assembly.
Furthermore, in the above technical solution, the number of the fans is three, and the fans are disposed on the housing at equal intervals, wherein the fan located in the middle is a reverse rotation fan, and the fans located on two sides are forward rotation fans.
Furthermore, in the above technical solution, the number of the fans is three, and the fans are disposed on the housing at equal intervals, wherein the fan located in the middle is a forward rotation fan, and the fans located on two sides are reverse rotation fans.
After the technical scheme is adopted, compared with the prior art, the utility model has following beneficial effect: the utility model discloses the during operation, whole fans rotate simultaneously, because the utility model discloses set up a fan in two adjacent fans into corotation fan, another fan sets up to the reversal fan to cause the air current that this corotation fan produced to flow through direction during the blind area clearance flows through the air current that the direction produced with the reversal fan is the same during the blind area clearance, and two air currents flow through promptly the blind area clearance can be assembled towards a direction, and the phenomenon that the convection current collided can not appear, thereby makes the utility model discloses an acoustic noise reduces, has two heat dissipation module who turns to the same fan relatively, the utility model discloses it has reduced 10-20% noise value than, more accords with the silence requirement to can improve the radiating effect, the order the utility model discloses extremely strong market competition has.
Description of the drawings:
