Description

Integrated fan pack

The present invention relates to an integrated fan assembly, in particular to an integrated fan assembly that can greatly improve the heat dissipation efficiency and reduce the overall noise of the fan.

Press, current mobile devices, personal computers, servers, communication boxes, or other systems or devices 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 of the product are becoming more and more diversified, 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 prone to overheating. Therefore, most electronic devices such as computers, servers, etc. usually only use one in them. The fan is used to dissipate heat, so that the electronic device can maintain a certain operating temperature range. Please refer to Figure 1. At present, the industry will install the same type of fans (axial fans) 10 side by side (in rows) in an accommodating space 110 of the electronic device 11 to increase the air volume and improve heat dissipation. However, Because the internal system design of the electronic device 11 is complicated, and the impedance of the fans 10 at different positions is different, each fan 10 draws or blows the air at different positions is different. As a result, each fan 10 may have a different degree of air volume attenuation, resulting in the overall The air volume becomes smaller and the heat dissipation efficiency decreases. In addition, since the same type of fans 10 are used in the accommodating space 110 of the electronic device 11 to be arranged side by side, when the fan 10 starts to operate, the same type of fans 10 will be affected by their flow field and The sound fields are similar, which causes the overall fan 10 to generate a huge noise. As mentioned above, the conventional knowledge has the following shortcomings: 1. Poor heat dissipation efficiency; 2. Large vortex; 3. The fan is noisy. Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the inventors of this case and the related manufacturers engaged in this industry urgently want to study and improve.

Therefore, in order to effectively solve the above-mentioned problems, the main purpose of the present invention is to provide an integrated fan assembly that can greatly improve the heat dissipation efficiency. The secondary objective of the present invention is to provide an integrated fan assembly capable of changing the vortex sound field structure. The secondary objective of the present invention is to provide an integrated fan assembly that can greatly reduce the overall noise of the fan. To achieve the above objective, the present invention provides an integrated fan set correspondingly installed in an accommodating space of an electronic device. The integrated fan set is composed of a plurality of different types of fans. At least one axial flow single fan and at least one centrifugal single fan are arranged in parallel and mixed. Through the design of this structure of the present invention, the axial flow single fan and the centrifugal single fan are installed in the limited accommodating space inside the electronic device at the same time, and the axial flow single fan can be installed according to the needs of the user. In other words, the use of the two different fan characteristics of the axial flow single fan and the centrifugal single fan to be used in parallel with each other can greatly improve the conventional use of a single type of fan (ie. Only the axial flow fan or centrifugal fan is installed in parallel), which results in the lack of poor heat dissipation efficiency, which improves the heat dissipation efficiency inside the electronic device. In addition, it can also destroy the regular sound produced by the conventional use of a single type of fan. The problem of huge noise caused by the field structure can destroy the eddy current to change the sound field structure of the eddy current and reduce the overall noise of the fan.

The above-mentioned objects and structural and functional characteristics of the present invention will be described based on the preferred embodiments of the accompanying drawings. Please refer to Figures 2 and 3, which are the three-dimensional schematic diagram and the three-dimensional exploded view of the first embodiment of the integrated fan set of the present invention.

In an accommodating space 30 of, the integrated fan group 2 is composed of a plurality of fans, and the fans are arranged in parallel and mixed with each other by at least one axial flow single fan 20 and at least one centrifugal single fan 21. , The plural fans in this embodiment are described as axial fans and centrifugal fans, but they are not meant to be limited. In actual implementation, other types of fans (such as cross-flow fans, etc.) can be selected according to the needs of users. The matching is arranged side by side in the accommodating space 30 of the electronic device 3, which is described first. The axial flow single fan 20 has a first frame 200 which forms an outer side wall 201, and the centrifugal single fan 21 has a second frame 210 corresponding to the second frame 210 Is assembled on the outer side wall 201. In addition, the first frame body 200 further forms a first accommodating space 203 to accommodate a first fan wheel 204, and the second frame body 210 further forms a second accommodating space 213 to accommodate A second fan wheel 214, the plurality of blades formed on the first and second fan wheels 204, 214 may have different sizes, the number of blades, the shape of the blades, and the size of the first and second fan wheels 204, 214 The speed can be different. The outer side wall 201 of the aforementioned first frame body 200 further includes a first side wall 2011 and a second side wall 2012, and the second frame body 210 further has a top side 211 and a bottom side 212, the top side 211 and the bottom side 212 The aforementioned second accommodating space 213 is defined together. In this embodiment, the bottom side 212 of the second frame 210 is correspondingly assembled on the first side wall 2011 of the first frame 200, and the second frame The bottom side 212 of the body 210 can be optionally assembled on the outer side wall 201 of the first frame 200 by screwing, locking, snapping, buckling, bonding, or fitting. Of course, it can also be assembled on the outer side wall 201 of the first frame 200. The bottom side 212 of the second frame body 210 is installed on the second side wall 2012 according to the size and direction of the content space 30 of the electronic device 3, and the configuration is completely in accordance with the needs of the user. Please refer to FIG. 4 again for the second embodiment of the present invention. The first side wall 2011 of the first frame 200 is installed with the centrifugal single fan 21, and the second side wall 2012 is installed with another axial flow unit. The body fan 20 (or as shown in FIG. 5, which is the third embodiment, the centrifugal single fan 21 is installed on the second side wall 2012 of the other axial flow single fan 20). Please refer to Figure 6, the centrifugal single fan 21 can be set vertically according to user needs, and can also be adjusted horizontally (the fourth embodiment of the present invention), in addition, the first frame 200 The first and second side walls 2011 and 2012 can also be equipped with the aforementioned centrifugal single fan 21 (please refer to FIG. 7, which is the fifth embodiment of the present invention), and the same as the second frame 210 of the centrifugal single fan 21 The bottom sides 212 are mutually assembled.
