Description

Serial fan

Technical field

The present invention combines what is formed on a kind of serial fan, especially a kind of be serially connected by least two fans Serial fan.

Background technology

Existing serial fan is serially connected by several fans and is formed, using several fans lifting air quantity, to reach whereby To preferable heat dissipation effect；However, vibrations situation would generally be produced during general fan running, therefore, by several fan institutes The existing serial fan formed is applied to various electronic system（Such as host computer）When caused vibrations situation also phase To serious, wherein the vibrations situation can not only produce noise, can also reduce the running stability of electronic system, cause electronic system Internal electronic component contact does sth. in advance tired and aging, shortens the service life of electronic system.

For this reason, it refer to shown in Fig. 1, such as " anti-vibration structure of tandem fan " hair of TaiWan, China bulletin I 324504 Bright Patent Case, discloses a kind of existing serial fan 9 with incabloc function.The serial fan 9, which includes, is serially connected knot Two fan frames 91,92 closed, which is respectively provided with a pedestal 911,921, and two pedestal 911,921 is tying Unify impeller, and a shock-absorbing element 93 is provided between the face and face of two fan frame 91,92 series combinations, the shock-absorbing element 93 It is made of the elastic material for having shock-absorbing and damping vibration concurrently, whereby, should when the impeller inside two fan frame 91,92 operates Shock-absorbing element 93 can be used to buffer and absorb vibrations caused by the impeller, is total to reduce that two fan frame 91,92 formed Effect of shaking and vibrating noise.

However, since the impeller of above-mentioned existing serial fan 9 is rotatably engaged in the pedestal of the fan frame 91,92 911st, 921, therefore, the impeller caused vibrations in operation process have vibrations bang path, namely via the pedestal 911st, 921 it is transferred to fan frame 91,92 and produces vibrations situation, although the serial fan 9 is reduced using the shock-absorbing element 93 The resonance effects and vibrating noise that two fan frame 91,92 is formed, but its damping effect is fairly limited, therefore work as the tandem wind When fan 9 is applied to electronic system or has the electronic system of hard disc, the running which can equally reduce electronic system is steady It is qualitative, or even cause hard disc can not read signal, and unnecessary noise can be still produced, cause the service life of electronic system to drop It is low.

The content of the invention

Present invention is primarily aimed at a kind of serial fan is provided, the bang path of vibrations can be effectively blocked, to more Caused vibrations situation when comprehensively and efficiently reducing serial fan running, during for applied to electronic system, can tie up Hold the running stability of electronic system and reduce vibrating noise person.

To reach aforementioned invention purpose, serial fan of the present invention includes at least two fans of opposite series combination, should Fan includes a fan frame, a drive component and an impeller, which includes an outline border and a pedestal, which is equipped with two wind-guidings Mouthful, a flow-guiding channel is equipped between two air guide hole, which is arranged at the pedestal of the fan frame, which rotatably ties Close the drive component；The outline border of wherein at least one fan is equipped with a positioning hole, and the location hole of the outline border has a minimum diameter, The pedestal has a maximum outside diameter, which is less than or equal to the minimum diameter；Also, the location hole is preferably equipped with one axially Location shoulder, which is incorporated into the location hole and abuts the axially position shoulder, it is preferred that the lateral wall of the pedestal is outer with this A radial direction buffer gap can be more formed between the madial wall of the location hole of frame.
