Technical Field
The present invention relates to an integrated fan assembly, and more particularly, to an integrated fan assembly capable of greatly improving heat dissipation efficiency and reducing overall noise of a fan.
Background
In current mobile devices, personal computers, servers, communication cabinets or other systems or devices, as the performance of computing is improved, the heat generated by internal heating elements (such as but not limited to chips) is also improved, and the functions of current electronic devices are more and more diversified, and various heating elements are disposed on the substrate. However, when the electronic device is operated, the heating element generates high heat, and if the heat cannot be conducted to the outside of the electronic device in time, the electronic device is easily overheated, so that most of electronic devices such as computers and servers usually use only one fan for heat dissipation, so that the electronic device can operate in a certain operating temperature range.
Referring to fig. 1, in the prior art, fans (axial fans) 10 of the same type are installed side by side (in a row) in an accommodating space 110 of an electronic device 11 to increase air volume and improve heat dissipation, however, because the internal system design of the electronic device 11 is complex and the impedances of the fans 10 at different positions are different, the air draft or blowing volume of each fan 10 at different positions is different, which may cause air volume attenuation of each fan 10 to different degrees, which results in reduced overall air volume and reduced heat dissipation efficiency, and in addition, because the fans 10 of the same type are installed in parallel in the accommodating space 110 of the electronic device 11, when the fans 10 start to operate, the fans 10 of the same type generate huge noise due to the fact that the flow field and the sound field are similar.
As described above, the prior art has the following disadvantages:
1. the heat dissipation efficiency is poor;
2. the eddy current is large;
3. the fan is noisy.
Therefore, how to solve the above-mentioned problems and disadvantages is a direction in which the inventors of the present invention and related manufacturers engaged in the industry need to research and improve.
