Patent Application
20210277916
The subject matter herein generally relates to fan frames, and more particularly to a fan module for use in an electronic device.
In some environments with high heat dissipation requirements (such as large servers), multiple fans are required. In order to connect multiple fans in series, generally a fastening structure is provided at a joint portion between adjacent fan frames to lock and connect the fan frames in series. However, such fastening structures may have problems such as instability in axial and horizontal directions of the fan frame, and installation and disassembly may be inefficient.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
The fan module 1 includes a first fan frame 10 and a second fan frame 20. A shape of each of the first fan frame 10 and the second fan frame 20 is substantially a hollow cylinder. Each of the first fan frame 10 and the second fan frame 20 is configured to receive a fan.

In a process of unlocking the first fan frame 10 from the second fan frame 20, the first fan frame 10 is rotated such that latching post 111 leaves the latching groove 211 and the positioning portion 121 moves away from the side wall 2211 toward the open end 2212, until the first fan frame 10 and the second fan frame 20 are separated from each other.
In one embodiment, a sloped surface 231 is located adjacent to the latching groove 211 on a side of the latching groove 211 away from the side wall 2211. The sloped surface 231 is gradually recessed in a direction away from the latching groove 211. The latching post 111 may be half-cylindrical in shape, and the latching groove 211 is correspondingly semi-cylindrical in shape. The sloped surface 231 and the shapes of the latching post 111 and the latching groove 211 can improve a process of engaging or disengaging the latching post 111 and the latching groove 211 to improve a user experience.
In other embodiments, the number of each of the latching members 11, the latching grooves 211, the latching posts 111, the positioning portions 121, and the rotating grooves 221 is not limited to four, as long as the two fan frames are capable of locking together with no relative displacement.
In other embodiments, the side surface 12 of the first fan frame 10 and the side surface 22 of the second fan frame 20 are provided with surface markers 30, which indicate a rotation direction of assembly of the first fan frame 10 and the second fan frame 20 and a wind direction of a fan 3, so that a user can accurately and quickly assemble the fan module 1.
In one embodiment, the side of the first fan frame 10 defining the opening 13 and the side of the second fan frame 20 defining the opening 23 each define a wiring groove 40.
Referring to
The fan module 1, 2 is simple to install and disassemble, thereby improving efficiency. Furthermore, engagement between the latching posts 111 and the latching grooves 211 restricts a tangential relative displacement of the fan module 1, 2, and engagement between the rotating grooves 221 and the positioning portions 121 restricts an axial displacement of the fan module 1, 2.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
