Embodiment Construction

[0031] In order to make the above-mentioned and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention are specifically cited below, together with the accompanying drawings, as follows:

[0032] Please refer to Figure 4 As shown, the tandem fan frame module of the preferred embodiment of the present invention includes several sash frames 1 , a series buckle assembly 2 and a radial auxiliary anti-rotation assembly 3 . Each of the fan frames 1 is arranged and combined in series; the series buckle assembly 2 is arranged on each of the fan frames 1, so as to have both axial anti-disengagement and radial anti-rotation functions; the radial auxiliary anti-rotation assembly 3 is also arranged on each of the fan frames. The fan frames 1 are used to strengthen the radial anti-rotation function between the fan frames 1 .

[0033] The fan frame 1 can be an axial flow fan frame or a centrifugal fan frame, a...

Abstract

The invention discloses a tandem fan frame module. The tandem fan frame module comprises a plurality of fan frames, a tandem buckle assembly and a radial auxiliary anti-rotating assembly, wherein the plurality of fan frames are arranged in series; the tandem buckle assembly is arranged in each fan frame and combining the fan frames; and the radial auxiliary anti-rotating assembly is arranged in each fan frame and comprises at least one limiting piece and at least one stopping piece, wherein the limiting piece and the stopping piece are respectively arranged on the jointed part of the two adjacent fan frames, and the limiting piece is propped against the stopping piece. Therefore, by matching the radial auxiliary anti-rotating assembly, the radial anti-rotating function of each fan frame is enhanced, and the integral structural strength is further promoted.

Description

technical field [0001] The present invention relates to a tandem fan frame module, in particular to a tandem fan frame module that combines several sash frames in series and simultaneously has the functions of anti-separation in the axial direction and anti-rotation in the radial direction. Background technique [0002] The existing tandem fan frame module is roughly like the invention patent case of Taiwan Announcement No. 569663 "Serial Module of Cooling Fan", please refer to figure 1 shown. The existing serial fan frame module 8 includes a first fan unit 81, a second fan unit 82 and two joints 83, 84; the two joints 83, 84 are used to make the first fan unit 81 and the The second fan unit 82 is arranged in series and combined for positioning, one of the connecting parts 83 is a plurality of slots, and the other connecting part 84 is a plurality of buckles. [0003] The existing tandem fan frame module 8 mainly utilizes the fastening combination of the two joints 83, 84 ...
