[0002] Generally, electronic devices and products are equipped with fans to dissipate heat directly or indirectly. High-speed fans are usually used to achieve better heat dissipation efficiency, but they also have a higher vibration frequency. When fans rotate at high speed, they generate vibrations, which can be transmitted to nearby devices, causing noise, damaging nearby devices, and reducing the lifespan of electronic devices and products.
[0003] A tandem fan connects two fans together via their fan frames, achieving higher static pressure and airflow. In existing technology, the structural design of tandem fans typically utilizes a snap-fit structure between the two fan frames, connecting them by rotation. However, this rotational snap-fit structure is complex and requires manual assembly. Furthermore, separating the two fans using this rotational design is difficult and prone to damage.

[0057] Figure 1 A perspective view of a series sector frame assembly 100 according to an embodiment of this application is shown, and Figure 2 Show Figure 1 An exploded view of the series-connected sector frame assembly 100. See also... Figure 1 and Figure 2 The series-connected fan frame assembly 100 includes a first fan frame 110 and a second fan frame 120. The bottom of the first fan frame 110 has an extension structure 111. The extension structure 111 extends from a corner of the first fan frame 110 toward the second fan frame 120 along an axial direction. That is, the extension structure 111 extends in direction D. The end of the extension structure 111 includes a first latch 112. The first latch 112 extends in direction A, perpendicular to direction D. When the series-connected fan frame assembly 100 is formed, the second fan frame 120 is located below the first fan frame 110. The second fan frame 120 has a sidewall structure 121 adjacent to the top outer edge of the first fan frame 110. The sidewall structure 121 is a recessed structure that engages the extension structure 111 of the first fan frame 110. The sidewall structure 121 includes a groove 122 and a second latch 124.
[0058] The second latch 124 is aligned with the groove 122 in direction D.
[0059] exist Figure 2 In this configuration, the first frame 110 and the second frame 120 are used to further mount the motor and the axial fan impeller, respectively. At this time, the rotation axis of the motor and the axial fan impeller is in the same direction as direction D.
[0060] When assembling the series-connected sector frame assembly 100, the first sector frame 110 can be moved and pressed down in direction D toward the second sector frame 120, so that the first sector frame 110 and the second sector frame 120 are connected in series. According to the aforementioned design, when assembling the first sector frame 110 and the second sector frame 120, the first latch 112 of the extension structure 111 of the first sector frame 110 can first be aligned with the side wall structure 121 of the second sector frame 120, and then guided by the groove 122 of the side wall structure 121 to slide in direction D, and then coupled to the second latch 124 of the side wall structure 121 of the second sector frame 120.
[0061] In some embodiments, the top view of the first sector frame 110 and the second sector frame 120 is approximately rectangular. The bottom of the first sector frame 110 has four axially extending structures 111, and the top of the second sector frame 120 may have four side wall structures 121. In this embodiment, the four extending structures 111 of the first sector frame 110 may be located at the four corners of the first sector frame 110 (i.e., at the diagonal endpoints), and the four side wall structures 121 of the second sector frame 120 may be located at the four corners of the second sector frame 120, with the positions of the four extending structures 111 corresponding to the positions of the four side wall structures 121 (e.g., aligned in the axial direction) to improve the stability of the first sector frame 110 and the second sector frame 120 after being connected.
[0062] The following description will detail the extension structure 111 of the first sector frame 110 and the side wall structure 121 of the second sector frame 120.
[0063] Figure 3 Show Figure 2 A magnified view of the first sector 110 from another perspective, and Figure 4 Show Figure 2 A magnified view of a portion of the second sector 120. See also... Figure 2 , Figure 3 and Figure 4The first latch 112 of the extension structure 111 of the first sector frame 110 can be a protrusion extending in direction A. The first latch 112 has a convex surface 115, and the bottom end of the first latch 112 has a first chamfered surface 113. The second latch 124 of the side wall structure 121 of the second sector frame 120 has the same central axis C as the groove 122, that is, it is aligned in the vertical direction. The second latch 124 has a concave surface, which can be a groove. In addition, the groove 122 has a second chamfered surface 123. The second chamfered surface 123 is located at one end of the groove 122 adjacent to the second latch 124, and gradually expands outward downward in direction D. With the above configuration, when the first frame 110 and the second frame 120 are assembled, the first chamfered surface 113 of the first buckle 112 can be guided by the groove 122 to abut against the second chamfered surface 123. Since the second chamfered surface 123 gradually expands outward in the direction D, the first chamfered surface 113 is guided by the second chamfered surface 123, allowing the first buckle 112 to slide over the groove 122 and the second chamfered surface 123. After the first buckle 112 has completely passed the step 126 downward, it is positioned and coupled to the second buckle 124. At this time, the convex surface 115 of the first buckle 112 abuts against the concave surface of the second buckle 124.
[0064] In some embodiments, the distance H1 between the upper edge of the first latch 112 and the lower edge of the first sector frame 110 is substantially the same as the distance H2 between the upper edge of the groove 122 and the upper edge of the second latch 124, and the diameter of the groove 122 is larger than the diameter of the first latch 112, so that the first latch 112 can be smoothly guided by the groove 122 and reliably positioned by the second latch 124. Figure 3 The first buckle 112 and Figure 4 After the second buckle 124 is coupled, it can be obtained Figure 5 The structure.
[0065] Furthermore, in this embodiment, the second snap fastener 124 has two opposing chamfered ribs 125, and the first snap fastener 112 is positioned between these two chamfered ribs 125. The chamfered ribs 125 are convex surfaces, extend axially, and are parallel to and adjacent to the first snap fastener 112. After the first sector frame 110 and the second sector frame 120 are assembled, the chamfered ribs 125 can improve the horizontal (radial) stability. In addition, when disassembling the first sector frame 110 and the second sector frame 120, because the chamfered ribs 125 have chamfers, the first sector frame 110 can easily rotate horizontally to slide the first snap fastener 112 along the surface of the chamfered ribs 125, so that the first sector frame 110 and the second snap fastener 124 can be easily separated.
[0066] In some implementations... Figure 3 The extension structure 111 of the first sector frame 110 has a first groove 114 adjacent to the first buckle 112. Figure 4The second sector frame 120 has a second groove 127 adjacent to the sidewall structure 121, and the second groove 127 is axially aligned with the first groove 114. (See also...) Figure 5 When the first sector frame 110 and the second sector frame 120 are combined to form Figure 1 When the fan frame assembly 100 is connected in series, the first groove 114 and the second groove 127 can define through holes (e.g., screw holes) that can accommodate fasteners (e.g., screws) for easy locking.
[0067] It should be understood that the component connections, materials, and functions already described will not be repeated, but will be stated in the preceding text. The following description will explain other components that may be included in the series sector frame assembly.
[0068] Figure 6 Show Figure 1 The cross-sectional view of the series fan frame assembly 100 along line segment 6-6 is shown. The series fan frame assembly 100 may further include a first support ring 130 and a second support ring 140. The first support ring 130 is embedded in the inner sidewall of the first fan frame 110, and the second support ring 140 is embedded in the inner sidewall of the second fan frame 120, and the second support ring 140 is separate from the first support ring 130. The first support ring 130 and the second support ring 140 may be fixed to the first fan frame 110 and the second fan frame 120 respectively by insert molding. The material of the first support ring 130 is different from the material of the first fan frame 110, and the material of the second support ring 140 is different from the material of the second fan frame 120. For example, the material of the first support ring 130 and the material of the second support ring 140 are metal, and the material of the first fan frame 110 and the material of the second fan frame 120 are plastic. The configuration of the first support ring 130 and the second support ring 140 can effectively reduce the noise and vibration of the series fan frame assembly 100 during operation.
[0069] In summary, because the second snap-fit and groove of the sidewall structure of the second fan frame in the tandem fan frame assembly are axially aligned, the first snap-fit of the extension structure of the first fan frame can be easily guided by the groove of the second fan frame and then coupled to the second snap-fit of the second fan frame during assembly, thus improving assembly efficiency. Furthermore, the tandem fan frame assembly with a first support ring and a second support ring effectively reduces noise and vibration.
[0070] The foregoing outlines the features of several embodiments, enabling those skilled in the art to better understand the manner of this application. Those skilled in the art should understand that they can readily use this application as the basis for designing or modifying other processes and structures to achieve the same objectives and / or advantages as the embodiments described herein. Those skilled in the art should also recognize that such equivalent constructions do not depart from the spirit and scope of this application, and that various changes, substitutions, and modifications can be made to them without departing from the spirit and scope of this application.
