Description

Tandem fan combinative structure

Technical field

The present invention relates to a kind of tandem fan combinative structure, particularly relate to one and fan vibration can be greatly reduced Tandem fan combinative structure.

Background technology

Along with the continuous progress of science and technology, people are consequently increased for the dependency of various electronic equipments；So And, operationally, the element of electronic product (such as computer, mobile computer) inside can produce height Heat, if cannot derive outside electronic product by heat in time, then easily produces overheated problem, therefore The electronic product of major part often uses a fan in it, allows electronic product be able to maintain that in certain operation temperature Operate under degree scope.

Referring to Figure 1A, 1B, its fan frame 10 of the existing tandem fan of current industry 1 is all same size institute Constitute, and this fan frame 10 forms fan with the assembling parts such as impeller 11, motor (not shown).When During fan running, the design principle of motor torque operating itself will necessarily produce vibration, wind of particularly connecting Fan, the structure of prior art tandem fan, it is only by the buckle structure between fan frame 10 and fan frame 10 12 are in series, and this series system causes changing vibrational state owing to combining along fan center's axle, when During the rotational run simultaneously of the impeller 11 within two fan frame 10, under the bobbing machine frequency reciprocal effect of two impellers 11, Two fan frame 10 can be caused to produce serious resonance effect, and the vibration that this resonance effect produces can be by fan frame 10 are directly delivered to outside, the hard disk in electronic product host computer system, very sensitive for vibration, and Because of the fan frame 10 of the single constituent part of traditional design, cause cannot effectively reducing vibration, even more serious Vibration produced by words, motor and impeller 11 can disturb the normal work of other electronic components, causes system Best efficiency cannot be played, and, also supervene huge noise while resonance effect.

The above, prior art has a following shortcoming:

1. cannot effectively reduce the vibration of fan；

2. fan vibration produces serious noise；

3. reduce system disk reading efficiency.

Therefore, how to solve above-mentioned existing issue and disappearance, be the inventor of this case and be engaged in this journey The place, direction of the relevant manufactures improvement to be studied of industry.

Summary of the invention

Therefore, for effectively solving the problems referred to above, present invention is primarily targeted at offer one can significantly drop The tandem fan combinative structure of low fan vibration.

The secondary objective of the present invention, is to provide a kind of series connection reducing noise produced by fan vibration Fan combination structure.

For reaching above-mentioned purpose, the present invention provides a kind of tandem fan combinative structure, including a connection piece group, One first fan and one second fan, this connector group have one first connector have one first end face and Second end face of one contrary first end face, one of this first connector upper end is from this first end face level outwardly Extended have one second connector, and a lower end of this first connector is prolonged from this second end face level outwardly Stretch and be provided with one the 3rd connector, wherein said second connector and the horizontal-extending direction of the 3rd connector On the contrary, a passage is formed at this first and second end face centre；

Described first fan docks the first end face of this first connector, and this first fan has one first fan Frame and a first flow run through this first fan frame, and this first fan frame connects this second connection at a horizontal level Part, this first flow connects described passage；

Described second fan docks the second end face of this first connector, and this second fan has one second fan Frame and one second runner run through this second fan frame, and this second fan frame connects the 3rd connection at a horizontal level Part, passage described in this second flow passage.

By the design of this structure of the present invention, be combined by described first fan with this first end face and connect This second connector, and described second fan is combined with this second end face and connects the 3rd connector, To make described connector group and the first fan and the second fan be connected with each other combination, enter fan is greatly reduced Produced vibration and noise when operating, and the effect of system disk reading efficiency can be improved.
