Description

Integrated fan set

This creation is about an integrated fan group, especially an integrated fan group that can greatly improve the cooling efficiency and reduce the overall fan noise.

According to the press, current mobile devices, personal computers, servers, communication cases, or other systems or devices all have improved computing performance, and the heat generated by their internal heating elements (such as but not limited to chips) has also increased, and current electronic equipment The functions are becoming more and more diverse, and various heating elements are provided on the substrate. However, during operation, the heating element generates high heat. If the heat cannot be exported to the outside of the electronic device in time, it is easy to cause overheating problems. Therefore, most electronic devices such as computers and servers usually only use one. The fan is used for heat dissipation, so that the electronic device can be operated within a certain operating temperature range.

Please refer to FIG. 1, at present, the industry will install fans (axial fans) 10 of the same type side by side (row) in a receiving space 110 of the electronic device 11 to increase the air volume and improve the heat dissipation, however Due to the complicated internal system design of the electronic device 11 and the different impedances of the fans 10 at different locations, each fan 10 has a different amount of air extraction or blowing at different locations, resulting in each fan 10 may have different degrees of air attenuation, resulting in an overall The air volume becomes smaller and the heat dissipation efficiency decreases. In addition, since the same type of fan 10 is used in parallel in the accommodating space 110 of the electronic device 11, the When the fan 10 starts to operate, the fan 10 of the same type will generate huge noise due to the similar flow field and sound field.

As mentioned above, conventional knowledge has the following disadvantages: 1. Poor heat dissipation efficiency; 2. Large eddy current; 3. Large fan noise.

Therefore, how to solve the above-mentioned problems and deficiencies in practice is the one where the creators of this case and the relevant manufacturers engaged in this industry are desperate to study the direction of improvement.

Therefore, in order to effectively solve the above problems, the main purpose of this creation is to provide an integrated fan set that can greatly improve the heat dissipation efficiency.

The secondary purpose of this creation is to provide an integrated fan set that can change the sound field structure of the vortex.

The secondary purpose of this creation is to provide an integrated fan set that can greatly reduce the overall noise of the fan.

To achieve the above purpose, this creative department provides an integrated fan group, which is correspondingly installed in one of the accommodating spaces of an electronic device. The integrated fan group is composed of a plurality of fans in different forms. At least one axial-flow single fan and at least one centrifugal single fan are arranged side by side and mixed.

Through the design of this structure, the axial unit fan and the centrifugal unit fan are installed in the limited space inside the electronic device, and the axial unit can be separated according to the user's needs. The body fan and the centrifugal single fan are arranged side by side. In other words, the use of two different fan characteristics of the axial single fan and the centrifugal single fan are used in parallel with each other, which can greatly improve the conventional use of a single type of fan (ie. Only parallel axial fans or centrifugal fans Installation) Parallel use causes the lack of poor heat dissipation efficiency, which improves the heat dissipation efficiency inside the electronic device. In addition, it can also destroy the conventional sound field structure generated by a single type of fan and generate huge noise. The effect of destroying the vortex to change the sound field structure of the vortex to reduce the overall noise of the fan.

The above-mentioned objects, structural and functional characteristics of this creation will be explained based on the preferred embodiments of the attached drawings.

Please refer to Figures 2 and 3, which is a three-dimensional schematic diagram and an exploded perspective view of the first embodiment of the integrated fan group created as shown in the figure. As shown in the figure, an integrated fan group 2 is correspondingly installed in an electronic device 3 In an accommodating space 30, the integrated fan group 2 is composed of a plurality of fans, and these fans are composed of at least one axial-flow single fan 20 and at least one centrifugal single fan 21 arranged side by side and mixed together. It should be noted that In this embodiment, the plural fans are described by axial fans and centrifugal fans, but they are not limited. In actual implementation, other types of fans (such as cross-flow fans, etc.) can be selected according to user needs The collocation is arranged side by side in the accommodating space 30 of the electronic device 3, which will be described first.
