Description

Serial fan structure

【Technical field】

The present invention relates to a series fan structure, especially a series fan structure which can greatly improve the noise generated by the vibration of the known series fan and increase the air flow.

【Background technique】

With the continuous advancement of technology, people's dependence on various electronic devices has also increased; however, during operation, the components inside electronic products (such as computers, notebook computers) will generate high heat. If the heat cannot be dissipated in time Out of the electronic products, it is easy to cause overheating problems, so most of the electronic products often use a fan to keep the electronic products in a certain operating temperature range.

Please refer to FIG. 1 , currently known series fan 1 has fan frames 10 of the same size, and the fan frame 10 is assembled with fan wheel 11 , motor (not shown in the figure) and other components to form a fan. When the fan is running, the design principle of motor torque operation itself will inevitably vibrate, especially the series fan formed by connecting more than two fans in series. According to the structure of the known series fan, it only passes through the fan frame 10 and the buckle structure or screw lock structure 12 between the fan frames 10 are connected in series. This series connection cannot change the vibration state due to the combination along the central axis of the fan. When the fan wheels 11 inside the two fan frames 10 rotate at the same time, Under the influence of the vibration machine frequency interaction of the two fan wheels 11, the two fan frames 10 will have a serious resonance effect, and the resonance effect will also cause the series fan to generate huge noise. In addition, it is known that when the series fan is running, due to the two The fan frames are directly connected in series, so the air volume inhaled by the fan cannot be completely exhausted by another fan (there will be a problem of partial air volume being lost when it is transmitted from one fan to another fan), which leads to the known series fan. The wind flow is small.

The above, known to have the following disadvantages:

1. The vibration of the fan cannot be effectively reduced;

2. The fan produces serious noise due to vibration;

3. The wind flow is small.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the inventor of this case and related manufacturers engaged in this industry want to study and improve urgently.

【Content of invention】

Therefore, in order to effectively solve the above problems, the main purpose of the present invention is to provide a serial fan structure that can greatly improve the noise and vibration problems of the serial fan.

The secondary purpose of the present invention is to provide a serial fan structure with the effect of increasing air flow.

To achieve the above object, the present invention provides a series fan structure, including a series fan group and at least one first combination part, the series fan group has a first fan connected in series with a second fan, the first fan has a The first base and a first side wall jointly define a first passage, and a plurality of first support parts extending outward from the first base are connected to the first side wall, and a first communication is formed between the first support parts The space communicates with the first channel, the second fan has a second base and a second side wall and jointly defines a second channel, the second channel communicates with the first channel and the first communication space, the first The combination part is correspondingly formed in the first communication space and connected to the first support part, and the first combination part has a plurality of first holes communicating with the first and second passages.

Through the design of this structure of the present invention, the noise and vibration problems of the known serial fan can be greatly improved by forming the first combined portion with a plurality of first holes on the first communication space of the first base, And achieve the effect of improving air flow.
