Detailed Description
The present utility model is further described below in conjunction with embodiments, which are merely some, but not all embodiments of the present utility model. Based on the embodiments of the present utility model, other embodiments that may be used by those of ordinary skill in the art without making any inventive effort are within the scope of the present utility model.
As in the prior art exemplified in the background art of the present utility model, in the setting process, the existing fans directly spray the electronic devices or directly spray the cooling fins on the electronic devices, and the following problems occur in the use process of the structural design:
1. the fan is directly arranged on the outer side of the electronic device and/or the radiating fin to directly blow the electronic device and/or the radiating fin, but hot air after blowing also flows around the electronic device and/or the radiating fin, so that the hot air cannot be quickly separated from the electronic device and/or the radiating fin.

At present, the fan is directly provided with the periphery of an electronic device and/or a radiating fin, when the fan needs to be cleaned (after the fan is used for a long time, a plurality of dust can be adhered to blades of the fan to influence the air output of the fan), the whole equipment can be taken down to clean the fan only after the fan is stopped (so as to prevent the situation of electric shock), and the mode has larger defects in stopping and maintaining in some scenes.

Although fans with self-cleaning function are presented in the prior art, the manner of adding additional mechanical structure greatly increases the production and manufacturing costs.

When the self-cleaning fan module is used, when the electronic device and/or the cooling fin matched with the electronic device need to be provided with a fan for cooling, the frame body is arranged on the cabinet body for installing the electronic device, the vortex fan in the frame body faces the electronic device and/or the cooling fin matched with the electronic device for cooling, the vortex fan starts to work for sucking the electronic device and/or the cooling fin matched with the electronic device, so that the electronic device and/or the cooling fin matched with the electronic device is cooled, and hot air sucked by the vortex fan is discharged through the reducer sleeve and the pipeline through the air outlet connector, so that the cooling treatment of the electronic device and/or the cooling fin matched with the electronic device is achieved.
According to the utility model, the two vortex fans are designed in the frame body, the reducing sleeves of the two vortex fans are mutually communicated through the communicating pipeline, in the actual use process, when one vortex fan runs at low power, the other vortex fan runs at high power, because the high-power vortex fan has more induced draft and the low-power vortex fan has less induced draft, the wind speed (wind pressure) between the reducing sleeve of the high-power fan and the air outlet connector is larger, the wind speed (wind pressure) between the reducing sleeve of the low-power vortex fan and the air outlet connector is smaller, and the reducing sleeves of the two vortex fans are mutually communicated through the communicating pipeline, so that the wind speed (wind pressure) between each vortex fan and the air outlet connector is more balanced.
In the use process, when one vortex fan needs to be self-cleaned, the other vortex fan normally operates, and simultaneously, the two-position two-way electromagnetic valves are closed, so that hot air of the normally operating vortex fan is introduced into the reducing sleeve of the vortex fan needing to be self-cleaned through the communicating pipeline, and finally, the vortex fan needing to be self-cleaned is back-blown, so that the self-cleaning function is achieved.

In some embodiments, the communication of the communication conduit with the reducer sleeve 3 is closer to the vortex fan 2 than the communication of the reducer sleeve 3 with the conduit 4. Thereby facilitating drainage of the suction wind of the two vortex fans 2 (i.e., the first vortex fan 21 and the second vortex fan 22) through the communication duct.
In some embodiments, the size of the communicating conduit is smaller than the outer diameter of the reducer sleeve 3, so that the communicating conduit plays a role in diverting and draining at a certain cost.

The utility model realizes the unidirectional movement of the first vortex fan 21 and the second vortex fan 22 by arranging the first communication pipeline 23 and the second communication pipeline 24, so that the condition that suction air flows back and forth between the first vortex fan and the second vortex fan can not occur, and the suction air can be conveniently and rapidly discharged out of the whole fan module.
In some embodiments, the first communication pipe 23 can flow into the reducer sleeve 3 of the first vortex fan 21 along the hot wind direction in the reducer sleeve 3 of the second vortex fan 22, and the first communication pipe 23 is in the same direction as the hot wind direction in the reducer sleeve 3 of the first vortex fan 21; the second communication pipe 24 can be led into the reducer sleeve 3 of the second vortex fan 22 along the hot air direction in the reducer sleeve 3 of the first vortex fan 21, and the second communication pipe 24 is in the same direction as the hot air direction in the reducer sleeve 3 of the second vortex fan 22. That is, the first communication duct 23 and the second communication duct 24 do not affect the wind direction in the first vortex fan and the second vortex fan.
In the specific implementation, the first communication duct 23 and the second communication duct 24 are set according to the positions of the first vortex fan 21 and the second vortex fan 22. As shown in fig. 2, the first communication pipe 23 is connected to the reducing sleeve 3 of the first vortex fan 21 and the second vortex fan 22 in an inclined manner, so that the hot air led out from the reducing sleeve 3 of the second vortex fan 22 can flow along the direction of the suction air of the first vortex fan 22 through the first communication pipe 23; as also shown in fig. 2, the second communication pipe 24 is in an "S" shape, so that the suction air led out from the reducing sleeve 3 of the first vortex fan 22 can flow along the movement direction of the suction air of the second vortex fan, thereby avoiding the situation that the suction air of the two vortex fans collide with each other and impact, and facilitating the rapid discharge of the suction air out of the whole fan module, so as to achieve the effect of improving the heat dissipation efficiency.
