Therefore, compared with the conventional series fan frame, the series fan frame of the present invention has fewer components, which can reduce the manufacturing cost and reduce the assembly steps of the series fan, and the plurality of wires pass through the frame body After that, there is no need to repeat the action of pulling and straightening the wires, and there is almost no rework problem, which helps to greatly improve the assembly efficiency, and when the series fan is installed in the system or the series fan is packaged, the number of The wires are not easily scratched and have the effect of reducing the failure rate of series fans.

It is worth mentioning that, in some embodiments of the present invention, after passing the plurality of wires out of the container, further adhesive tapes such as acetate cloth can be used to attach the plurality of wires to the frame. The outer circumference of the body. In this way, even if the overall assembly efficiency will be slightly affected, the wires can be made closer to the outer peripheral surface of the frame, so as to reduce the probability of scratching the wires during assembly or packaging; At the position of the wires, foreign objects will only touch the tape and cannot directly touch the wires, so the protection of the wires can be improved, and the failure rate of the series fan can be further reduced.
