Description

Combination structure of series fans

technical field

The utility model relates to a combination structure of series fans, in particular to a combination structure of series fans which can quickly combine and position series fans by means of horizontal sliding clamping and can prevent vibration at the same time.

Background technique

With the advancement of technology, people's dependence on various electronic devices has also increased; however, the internal components of electronic products (such as computers, notebook computers) will generate high heat during operation. Outside the product, it is easy to cause overheating problems. Therefore, most electronic products often use a fan to keep the electronic product operating within a certain operating temperature range. However, sometimes the wind power that a single fan can provide may exceed Insufficient, so two or more fans are often connected in series and used together to provide sufficient wind power.

As disclosed in the new patent of "Cooling Device for Central Processing Unit" in Taiwan Patent Publication No. 481434, a cooling device for central processing unit includes cooling fins and at least two or more fans; It is characterized in that: the at least two first fans and the second fan are butted in series, and the distance between the two fans is formed by several connecting columns, so that when the heat sink absorbs the high temperature of the central processing unit , by providing a dual-tandem fan with supercharged large suction volume, and with improved cooling, cooling effect and speed.

This case further explains that the four corners of the fan frames of the two fans are provided with through holes for the first fan to be connected in series with the second fan by screws passing through the through holes of the two fans to be combined and locked on the heat sink.

However, this kind of combination of two fans by screws alone has its own problems in implementation, because the force applied by the two fans to the screw lock is on one side of a group of fans rather than on the joint surface of the two fans, resulting in a series connection. Insufficient joint force makes the fan prone to noise when it rotates, and the fluid overflows from the gaps in the joint to affect the air flow on the radiator and reduce the heat dissipation performance.

Furthermore, another combination method of the series-connected cooling fan in the prior art is to set a plurality of perforations in the four corners of one of the two fans to be combined in series, and to set at least one convex hole on the other fan corresponding to the aforementioned perforations. body, and insert the protrusions into the above-mentioned perforations correspondingly, so as to fix the two fans in series. Although this fixing method can fix the two fans in series, special fixtures are required for heavy industry disassembly after the combination. During the disassembly process It is easy to cause structural damage, and it is easy to increase the generation of defective products. Moreover, the tightness of the combination between the convex body and the perforation is not good, and then vibration and noise are generated, so it is very inappropriate. Therefore, the conventional technology has the following disadvantages:

1. Poor tightness produces vibration and noise;

2. Heavy industry is inconvenient and easy to increase defective products;

3. Inconvenient assembly results in increased man-hours.
