[0037] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] To address the problem of messy wiring in fan modules affecting airflow in related technologies, this application provides an electronic device fan module, an electronic device chassis module, and an electronic device.

[0039] like Figures 1 to 7 The electronic device fan module shown includes multiple fans 10 and a first frame portion 23, with the fans 10 arranged in a group; the first frame portion 23 is connected to the end of the fan 10, the first frame portion 23 has an extension section 24, the extension section 24 extends along the axial direction of the fan 10, the fan 10 has a fan terminal, the fan terminal is disposed on the extension section 24, and the fan terminal is located between two adjacent fans 10 in the same group.

[0040] In this embodiment, the fan terminal is positioned between the two fans 10 and on the extension section 24, ensuring the fan terminal is close to the fans 10 and eliminating the need for excessively long cables. This reduces cable usage, prevents cable clutter from interfering with airflow to the fans 10, ensures stable airflow, and thus guarantees effective heat dissipation. Simultaneously, the extension section 24 provides shelter for the fan terminal, utilizing the space beneath it to reduce the additional space occupied by the fan terminal. Furthermore, it facilitates insertion of the fan terminal into the connection terminal 50 when applying force to the extension section 24 during installation.

[0041] This embodiment uses a server as an example for illustration. The fan module is installed inside the chassis module to provide air cooling for components such as the processor and memory inside the server. Of course, the electronic device can also be a router or other similar device.

[0042] The electronic device fan module of this embodiment also includes a connection terminal 50. At least two fans 10 in the same group have their fan terminals electrically connected to the same connection terminal 50, so that when the fans 10 are installed, multiple fan terminals can be plugged into the same connection terminal 50 at the same time. This can reduce the number of connection terminals 50 and reduce the space occupied by the connection terminals 50 on the motherboard, and does not affect the individual control of the fans 10, ensuring individual signal control of different fans 10.

[0043] In this embodiment, the first frame portion 23, the fan terminal, and the connecting terminal 50 are all located on the air outlet side of the fan 10. The connecting terminal 50 can also be located within the downward projection range of the extension section 24. The projection of the extension section 24 on the plane where the air outlet of the fan 10 is located is outside the air outlet. In this way, both the extension section 24 and the connecting terminal 50 can be vertically offset from the air outlet on the air outlet side. The extension section 24 is located above the air outlet, and the fan terminal and the connecting terminal 50 are located below the air outlet. This ensures that the extension section 24, the fan terminal, and the connecting terminal 50 do not significantly affect the airflow from the air outlet acting on the rear device, thereby ensuring the stability of the airflow and ensuring efficient heat dissipation for the device. Moreover, the extension section 24 can also play a certain guiding role, reducing the outward diffusion of airflow and allowing the airflow to be concentrated on the device.

[0044] like Figures 1 to 3As shown, the electronic device fan module of this embodiment also includes a first frame portion 23. The second frame portion 22 and the first frame portion 23 are located on the air inlet side and air outlet side of the fan 10, respectively, allowing the second frame portion 22 and the first frame portion 23 to clamp and fix the fan 10 from both ends, ensuring stable and reliable installation of the fan 10. One second frame portion 22 and one first frame portion 23 cooperate to form a fan frame 20, within which the fan 10 is installed, thus accommodating and installing the fan 10. Furthermore, this embodiment employs a configuration where multiple fans 10 can be installed within a single fan frame 20; that is, multiple fans 10 in the same group are connected to the same second frame portion 22 and the same first frame portion 23. By installing multiple fans 10 on the same fan frame 20, the number of fan frames 20 can be reduced.

[0045] In this embodiment, a support section 21 is provided on the second frame portion 22. Both the support section 21 and the extension section 24 extend laterally away from the fan 10, so that the support section 21 and the extension section 24 extend away from each other. When the electronic device fan module is installed inside the chassis 40, the support section 21 is supported by the crossbeam 41 of the chassis 40. In this way, the fan frame 20 is installed inside the chassis 40 by using the support section 21, which can reduce the number of bolts required for the installation between the fan frame 20 and the chassis 40, or even eliminate the need for bolt connections. This reduces the impact of the fan module installation on the structural strength of the chassis 40, ensures good structural strength of the chassis 40, and thus ensures the overall stability and reliability of the electronic device.

[0046] The reason why the support section 21 is provided on the second frame portion 22 at the air inlet side in this embodiment is that it needs to cooperate with the crossbeam 41 of the chassis 40. Since the second frame portion 22 is located at the air inlet end, the crossbeam 41 at the air inlet end has little impact on the heat dissipation effect of the fan 10. However, if the crossbeam 41 is provided at the air outlet end, the crossbeam 41 may affect the airflow blown out at the air outlet end, causing problems such as disordered heat dissipation airflow and affecting subsequent heat dissipation. Therefore, in this embodiment, it is preferable to provide the support section 21 only on the second frame portion 22 located at the air inlet end to ensure that the fan module still has a good heat dissipation effect.

[0047] In this embodiment, the support section 21 has a support surface and a mounting surface that are arranged opposite to each other. Taking the fan module being installed into the chassis 40 from top to bottom as an example, the support section 21 extends approximately horizontally. The support surface is the lower surface of the support section 21, and the mounting surface is the upper surface of the support section 21. The support surface is supported on the crossbeam 41, while the mounting surface can abut and limit the fit with the top cover of the chassis 40 when the top cover is closed. In this way, the upper and lower sides of the support section 21 abut and limit the fit with the crossbeam 41 and the top cover, respectively, so that the position of the fan frame 20 can remain stable, avoiding accidental shaking and ensuring the stability of the fan module after installation.

[0048] In this embodiment, the extension section 24 is located at the top of the first frame portion 23 and is not lower than the inner top surface of the chassis 40, so that the upper surface of the extension section 24 can mate with the inner top surface of the cover. In this embodiment, it is preferable that the upper surface of the extension section 24 and the inner top surface of the cover are approximately the same height. The extension section 24 and the support section 21 have certain similarities. The similarity is that both can abut and limit the fit with the cover of the chassis 40. That is, when the cover is closed, the lower surface of the cover abuts and contacts the upper surface of the support section 21 and the upper surface of the extension section 24, so that both ends of the fan module can be limited by the cover, ensuring the overall installation position of the fan module is stable. The difference is that the lower surface of the support section 21 mates with the crossbeam 41, while the lower surface of the extension section 24 does not have the crossbeam 41 and will not mate with the crossbeam 41, thus not affecting the airflow and heat dissipation of the fan 10.

[0049] The aforementioned extension section 24 and support section 21, in addition to stabilizing the installation position, also facilitate assembly. Due to the design of the extension section 24 and support section 21, when installing the fan 10, personnel can pinch the extension section 24 and support section 21 to assemble the fan frame 20 and the fan 10 together. The entire fan module can also be installed into the chassis 40 by pinching the extension section 24 and support section 21. This increases the leverage points during assembly, making the insertion process simpler. Simultaneously, since the connecting terminal 50 is located directly below the extension section 24, when installing the fan 10, both fan terminals can simultaneously engage with one connecting terminal 50. When the fan 10 is pressed into place, both fan terminals are simultaneously inserted into the connecting terminal 50, achieving quick connection between the fan terminals and the connecting terminal 50, reducing installation complexity and cable usage.

[0050] Optionally, the cooperation method between the second frame portion 22 and the first frame portion 23 can be set as needed. They can be configured separately or as a single unit. This embodiment adopts a separate configuration, which facilitates processing and assembly and reduces the difficulty of use.

[0051] Optionally, the second frame portion 22 and / or the first frame portion 23 have installation marks for distinguishing the installation position. The installation marks include at least one of color, text, and pattern. In this embodiment, the installation marks are colored, so that the second frame portion 22 and the first frame portion 23 each present different colors, so that installers can distinguish the corresponding installation positions and avoid incorrect installation.

[0052] The second frame portion 22 of this embodiment has an observation hole 25 for observing the fan markings. The observation hole 25 can be a through hole, allowing personnel to easily observe information such as the silkscreen number on the fan 10. This eliminates the need for markings on the fan frame 20 to indicate the type of fan 10, thus eliminating the model correspondence between the fan frame 20 and the fan 10 and allowing the fan frame 20 to be reused. The specific location of the observation hole 25 can be set as needed. It can be set on the support section 21, the extension section 24, or other locations on the fan frame 20. In this embodiment, it is preferably set on the support section 21.

[0053] like Figure 2 As shown, in this embodiment, both the second frame portion 22 and the first frame portion 23 are inverted L-shaped structures. The longitudinal segment is the part that mates with the end face of the fan 10. It can be connected to the end face of the fan 10 by means of bolts or other structural means to realize the installation of the fan 10. The transverse segment is the support section 21 or the extension section 24, which is used to cooperate with the crossbeam 41, the top cover and other structural components to realize the installation and fixation between the fan frame 20 and the chassis 40.

[0054] like Figures 1 to 7 As shown, this embodiment also provides an electronic device chassis module for mounting the aforementioned electronic device fan module. The electronic device chassis module includes a chassis 40 and a cable management structure 30. The chassis 40 has a mounting cavity where the fan module, processor, memory, hard drive, and other components are mounted. The chassis 40 also has a crossbeam 41, which is horizontally positioned within the chassis 40. The electronic device fan module is detachably mounted within the chassis 40, and its support section 21 is supported on the crossbeam 41. The cable management structure 30 is also located within the chassis 40, and gaps exist between different groups of fans 10 within the electronic device fan module and between the electronic device fan module and the inner wall of the chassis 40. At least one gap is fitted with a cable management structure 30, which has a channel 31 for cables to pass through. The cable management structure 30 helps to organize cables, thereby preventing cables from affecting the fans 10 and other components.

[0055] like Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, a cable management structure 30 is provided at the middle position of the fan 10 arrangement direction, which is approximately the middle position of the width direction of the chassis 40. This is a central cable management structure. Simultaneously, a cable management structure 30 is also provided between the outermost fan 10 and the inner wall of the chassis 40. This is a side cable management structure, and a total of two side cable management structures are provided. The central and side cable management structures can have the same or different structural forms. In this embodiment, the central and side cable management structures have some similarities in some structures, but they are not completely identical. It should be noted that the following method of setting the central cable management structure can be applied to the side cable management structure, and vice versa.

[0056] The cable management structure 30 of this embodiment has a first side and a second side with relative openings. Cables can be inserted into and out of the channel 31 from the first side and the second side to realize the cable running. An installation port communicating with the channel 31 is provided at the top of the cable management structure 30, so that the cable can be inserted into the channel 31 from the installation port to realize the cable placement.

[0057] The intermediate cable management structure in this embodiment has a U-shaped structure, including an outer shell layer and an inner layer. The outer shell layer has a channel 31, and the inner layer is disposed on the inner wall of the channel 31 and is used to contact and cooperate with the cable. The outer shell layer is a metal layer, and the inner layer is a plastic layer. In this way, the metal outer shell layer can enhance the structural strength of the intermediate cable management structure and ensure the stability of its connection with the chassis 40, while the plastic inner layer can protect the cable and prevent the cable from being scratched or damaged.

[0058] like Figure 4 and Figure 7 As shown, both the middle cable management structure and the side cable management structure of this embodiment are provided with support covers 32 at their mounting openings. The support covers 32 are designed to be openable and closable. The support covers 32 can block or avoid the mounting openings, so that the support covers 32 open when the cable is inserted and close after the cable is inserted. This ensures that the cable can be inserted into the channel 31 and stably kept in the channel 31, avoiding accidental detachment.

[0059] Optionally, the specific configuration of the support cover 32 can be configured as needed. It can be a detachable snap-fit ​​type or a rotatable type. In this embodiment, a pivot is provided so that the support cover 32 can be flipped up and down. Flipping it upwards opens the support cover 32, and flipping it downwards closes the support cover 32. Figure 4As shown, for the intermediate cable management structure, this embodiment provides two support covers 32. The two support covers 32 can open or close simultaneously to block the mounting opening. A hand-tightening screw 33 is provided on each support cover 32 as a locking structure 33. The hand-tightening screw can lock the support cover 32 in the closed position, thus preventing the cable from accidentally opening and coming loose. Figure 7 As shown, for the side cable management structure, this embodiment only provides one support cover 32, and a buckle structure is provided on the support cover 32 as a locking structure 33, which is used to lock the support cover 32 in the closed position.

[0060] Optionally, the support cover 32 has a wire pressing structure, which can take the form of a protrusion or other structure. The wire pressing structure is used to further stabilize the position of the cable in the cable management structure 30. When the support cover 32 closes the installation port, the wire pressing structure is located in the channel 31 and presses down on the cable, so that the cable can be pressed tightly in the cable management structure 30, avoiding the situation where the cable swings randomly due to the channel 31 being too large.

[0061] In this embodiment, the chassis 40 is provided with a cover that can be closed. In addition to blocking the position of the installation port, the support cover 32 can also cooperate with the cover. When the cover is closed on the chassis 40, the cover will also abut against the upper surface of the support cover 32. In this way, the cable management structure 30 can be stably kept in the gap by the restriction of the cover, avoiding random shaking and falling off.

[0062] The top cover in this embodiment is the component that can contact and limit the upper surfaces of the support section 21 and extension section 24 of the electronic device fan module. Its specific cooperation is as described above and will not be repeated here.

[0063] Furthermore, the middle cable management structure can be equipped with mounting posts, and the lower surface of the top cover has fixing structures such as positioning posts and slides. The mounting posts are used to cooperate with the fixing structures of the top cover. When the top cover is closed, the fixing structures and mounting posts are locked together, thereby locking the top cover and the cable management structure 30 together, further ensuring the stability of the cable management structure 30.

[0064] Optionally, the electronic device chassis module also includes a deformable filler, which is disposed within the channel 31 and can seal the channel 31. In this embodiment, foam is mainly provided as a filler in the side cable management structure. The foam can clamp and fix the cable to prevent it from shaking, and can also seal the gap between the cable and the inner wall of the channel 31 to prevent airflow backflow.

[0065] In an embodiment not shown, the intermediate cable management structure also includes foam or other fillers. The main purpose of the foam is to fill the gap between the cable and the channel 31, preventing airflow backflow. Furthermore, when no cable is running through the intermediate cable management structure, the foam can seal the channel 31, thus also preventing backflow.

[0066] In an embodiment not shown, the cable management structure 30 may not contain any filler. In this case, the cable management structure 30 can be rotatably configured to achieve cable routing and gap sealing. The rotation axis of the cable management structure 30 extends approximately laterally and is approximately perpendicular to the axis of the channel 31. Thus, when the cable management structure 30 is rotated, it can switch between a routing position where the cable can pass through and a blocking position where the cable cannot pass through. Specifically, when the cable management structure 30 is rotated to the routing position, the first side faces the air outlet direction of the fan 10, and the connection direction between the first side and the second side is approximately the same as the cable routing direction, thereby allowing the cable to pass through the channel 31 from the second side and exit from the first side, thus achieving cable routing. When no cables are running through it, the cable management structure 30 rotates approximately 90 degrees to the blocking position. At this time, the first side and the second side face the bottom or top surface of the chassis 40, respectively. The direction of the connection between the first side and the second side is approximately perpendicular to the direction of the cable routing, thereby blocking the gap on the side of the cable management structure 30 and sealing the gap.

[0067] This embodiment also provides an electronic device, including a motherboard, the aforementioned electronic device chassis module, and the aforementioned electronic device fan module. The motherboard is disposed inside the electronic device chassis module, and the connection terminal 50 of the electronic device fan module is installed on the motherboard, thereby realizing the electrical connection between the fan 10 and the motherboard.

[0068] It should be noted that "multiple" in the above embodiments refers to at least two.

[0069] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0070] In this embodiment, the fan terminal is positioned between the two fans 10, and the connecting terminal 50 is positioned on the extension section 24. This allows the connecting terminal 50 to be close to the fan 10, eliminating the need for excessively long cables between the connecting terminal 50 and the fan 10; they can even be directly plugged in. This reduces cable usage, prevents cable clutter from interfering with airflow to the fan 10, ensures stable airflow, and thus guarantees effective heat dissipation. Simultaneously, the extension section 24 provides a shielding effect for the connecting terminal 50, utilizing the space beneath it to reduce the additional space occupied by the connecting terminal 50. Furthermore, it facilitates the insertion of the fan terminal into the connecting terminal 50 when applying force to the extension section 24 during installation.
