Description

  The present invention relates to an in-series fan assembly structure, and more particularly to an in-series fan assembly structure that can be quickly assembled and increases the axial and radial coupling density.

With the advancement of science and technology, the demand for various electronic devices is increasing for people every day. However, by operating electronic products (for example, personal computers and notebook personal computers), the amount of heat of internal components increases, and there is a problem of overheating if the heat is not immediately discharged to the outside. For this reason, a fan is installed in most electronic products, and the electronic products are maintained in a certain temperature range. However, since the wind power provided by a single fan is insufficient, two or more fans may be assembled and used in series.

In the cooling device used for the central processing unit, the cooling device includes a heat radiation piece and at least two or more fans. (See Patent Document 1 as an example). The feature is that the at least two first fans and the second fan are configured to be connected in series, and several connecting pillars form a distance between the two fans, When the heat dissipating piece reaches a high temperature in the absorption central processing unit, a series-type fan forms a sucked air that has been increased in pressure, enhancing cooling and increasing the temperature lowering effect.

The draft is used to install holes in the corners of the fan frames of the two fans and install the first fan in series with the second fan, and connect them through the holes of the two fans with screws. Secure to.

However, when two fans are connected with only this type of screw, a problem in implementation occurs. That is, when the two fans fix the screws, the force concentrates only on one side of the pair of fans and does not apply to the joint surface of the two fans. Therefore, shortage occurs in direct joining, noise is generated when the fan rotates, and at the same time, fluid leaks from the gap between the joining surfaces, affecting the air volume of the radiator and lowering the heat radiation function.

In addition, the structure of the known fixed series heat dissipation fan is high in cost, low in assembly strength, and inferior in bonding, so that after assembly, the fan easily vibrates in the radial and axial directions, and the fan rotates at high speed. The fan in the environment of the server and communication equipment becomes easy to loosen.

Furthermore, another known series-type heat radiation fan assembly method is to place a plurality of perforations at the four corners of one of the two fans to be assembled in series and to face the aforementioned perforations of another one fan. In addition, at least one convex body is installed, and the plurality of convex bodies are fitted into the perforations to fix the two fans in series. The one fixing method fixes two fans in series, but the fixing degree after the coupling is poor, so that vibration and noise are likely to be generated, which is not appropriate.
