Series fan assembly structure

Abstract

A series fan assembly structure includes a first fan and a second fan mated with the first fan. The first fan includes a first frame body and at least one mating section diagonally positioned on two opposite corners of one side of the first frame body. The second fan includes a second frame body and at least one connection section diagonally positioned on two opposite corners of one side of the second frame body corresponding to the mating section. The connection section is connected with the mating section, whereby the series fan assembly structure is easy to rework and has better vibration absorption effect.
