Benefits of technology

The present invention provides a fan serial connection structure that reduces and lowers the vibration and noise of the fan. This is achieved by fixing the first face of the connection member with the fan assembly, which reduces co-vibration and improves the efficiency of reading hard disks.

Problems solved by technology

In operation, the internal components of the electronic products (such as computers and laptops) will generate high heat.
Otherwise, the problem of overheating will take place.
Therefore, the vibration state of the fan cannot be changed.
The hard disk (such as the hard disk in a server) of the mainframe system of an electronic product is quite sensitive to vibration.
However, the conventional one-piece fan frame 10 can hardly reduce the vibration.
In some more serious cases, the vibration of the motor and the fan impeller 11 will even interfere with the normal work of other electronic components.
This will lead to deterioration of the performance of the system.
Moreover, the resonation is always accompanied by loud noise.
1. The vibration of the fan can be hardly effectively reduced.
2. The vibration of the fan will make loud noise.
3. The reading efficiency of the hard disk of the system is lowered.

third embodiment

[0035]In this embodiment, the assembling member 5 is disposed between the second and fourth openings 2022, 2122. The first end face 50 is assembled with the second opening 2022, while the second end face 51 is assembled with the fourth opening 2122. The passageway 52 correspondingly communicates with the first and second flow passages 202, 212. In this embodiment, the series fan assembly 2 is assembled with the assembling member 5 by means of engagement. In practice, the first and second fans 20, 21 can be assembled with the first and second end faces 50, 51 by any other means that can securely connect the first and second fans 20, 21 with the first and second end faces 50, 51, for example, by means of slide rail (as shown in FIGS. 4A and 4B, the present invention), locking, insertion, adhesion or latching. This is not limited.

[0036]Please now refer to FIGS. 5A and 5B. FIG. 5A is a perspective exploded view of a fourth embodiment of the fan serial connection structure of the present...

fifth embodiment

[0037]In this embodiment, the series fan assembly 2 is assembled with the assembling members 5 by means of locking. In practice, the first and second fans 20, 21 can be assembled with the first and second end faces 50, 51 by any other means that can securely connect the first and second fans 20, 21 with the first and second end faces 50, 51, for example, by means of slide rail (as shown in FIGS. 6A and 6B, the present invention), engagement, insertion, adhesion or latching. This is not limited.

[0038]According to the above structural design, the connection sections 214 of the series fan assembly 2 are correspondingly assembled with the connection member 3 and the assembling sections 53 of the assembling members 5. Accordingly, the series fan assembly 2 can be more securely connected with the connection member 3 and the assembling members 5. In this case, when the fans operate, the vibration frequencies of the fans are unified to offset or restrain the co-vibration of the series fan s...

Abstract

A fan serial connection structure includes a series fan assembly and a connection member. The series fan assembly includes a first fan and a second fan correspondingly serially connected with the first fan. The connection member is disposed on one side of the series fan assembly. The connection member has a first face and a second face opposite to the first face. The first face is correspondingly assembled with the side of the series fan assembly. According to the above structural design, the co-vibration of the series fan is offset or restrained to greatly reduce the vibration of the fan and lower the noise.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a fan serial connection structure, and more particularly to a fan serial connection structure, which can greatly reduce the vibration of the fan and lower the noise.[0003]2. Description of the Related Art[0004]Along with the continuous advance of sciences and technologies, the reliance of peoples on various electronic apparatuses has more and more increased. In operation, the internal components of the electronic products (such as computers and laptops) will generate high heat. The heat must be dissipated to outer side of the electronic products in time. Otherwise, the problem of overheating will take place. Therefore, most of the electronic products are provided with fans disposed therein for keeping the electronic products working at an operation temperature within a range.[0005]Please refer to FIGS. 1A and 1B. The fan frames 10 of the current series fan 1 have the same size....
