Description

Technical Field

[0001] The invention belongs to the technical field of servers, in particular to a server fan module. Background Art

[0002] A server provides computing or application services to other clients on a network. It features high-speed CPU computing power, long-term reliable operation, powerful I / O external data throughput, and improved scalability.

[0003] A server that uses air cooling usually has multiple server fan modules installed inside, and they are usually arranged side by side to provide directional cooling airflow inside the server chassis, thereby effectively cooling the internal components of the server and ensuring the normal and stable operation of each component of the server.

[0004] Traditional server fan modules (multiple) are typically positioned and installed using a fan bracket installed horizontally inside the server chassis. The fan module and fan bracket are typically mounted as follows: hollowed-out end plates on the fan bracket engage the front and rear ends of the fan module, and multiple fan rivets are used to position and install the fan module and fan bracket. The fan bracket is typically a one-piece sheet metal structure riveted to the chassis via multiple rivets. This results in a fixed installation position for the fan bracket, and installation and removal of the fan bracket from the chassis are cumbersome and inconvenient, resulting in high parts and labor costs. Furthermore, the fan bracket is fixed in position inside the server chassis, making it impossible to adjust flexibly and limiting. Furthermore, the end plates of the fan bracket block some of the fan module's airflow, preventing the server fan module from achieving its full cooling efficiency, resulting in performance loss. Summary of the Invention

[0005] To solve the above problems, the present invention provides a server fan module, in which the cooling fan body is easy and flexible to disassemble and assemble, and will not block the cooling airflow of the cooling fan body, thereby ensuring 100% cooling performance of the cooling fan body and improving cooling efficiency.

[0006] The present invention is achieved through the following technical solutions:

[0007] A server fan module includes a fan base and a fan locking seat that can be positioned and installed with a server chassis. Two fan positioning shafts that can position and install a cooling fan body are installed on the upper side of the fan base; a groove is provided in the middle of the upper side of the fan locking seat, and channels connected to the groove are provided at the left and right ends, and a fan locking plate is slidably provided in the channel; a boss that can be embedded in the groove is provided on the lower side of the fan base, and positioning plates that can engage with the left and right fan locking plates are provided on the left and right sides of the boss.

[0008] A further improvement of the present invention is that two positioning plug plates are provided on the lower side of the fan base, and a positioning slot capable of being inserted and positioned with the positioning plug plates is provided on the upper side of the fan lock seat.

[0009] A further improvement of the present invention is that the two positioning slots are respectively connected to the left and right channels, and a limiting protrusion with upward elastic support is provided on the upper side of the fan locking plate; when the fan locking plate is pulled outward, the limiting protrusion can be inserted upward into the positioning slot and can lift the positioning plug plate.

[0010] A further improvement of the present invention is that an elastic connecting plate is provided on the fan locking plate, and the limiting protrusion is provided at the end of the connecting plate.

[0011] A further improvement of the present invention is that a tension spring hook is provided on one side of the bottom surface of the groove close to the channel, a connecting pin is installed on the lower side of the fan lock plate, and a tension spring is connected between the connecting pin and the tension spring hook.

[0012] A further improvement of the present invention is that a sliding groove capable of guiding the connecting pin to slide left and right is provided on the side wall of the channel.

[0013] A further improvement of the present invention is that an opening and closing mark is provided on the upper side of the fan locking plate, and a display window capable of displaying the opening and closing mark is provided on the top of the channel.

[0014] A further improvement of the present invention is that a plurality of limiting seats for limiting the position of the fan base are provided on the upper side of the fan lock seat.

[0015] A further improvement of the present invention is that an upwardly bent operating portion is provided at the outer end of the fan locking plate, and a support plate is connected between the inner side of the operating portion and the fan locking plate; support plate positioning grooves that can be snap-fitted with the support plate are provided at the left and right ends of the fan locking seat.

[0016] A further improvement of the present invention is that the fan lock seat includes two split lock seats that are installed in a left and right manner; the lower sides of the two split lock seats are respectively provided with mounting slots with openings facing each other, and the mounting slots are used for engaging with I-pins on the server chassis for installation.

[0017] It can be seen from the above technical solutions that the beneficial effects of the present invention are:

[0018] The cooling fan body is positioned and installed with the fan base via two fan positioning shafts, and the fan locking seat is positioned and installed with the server chassis bottom plate. The two fan locking plates are guided inward by the channel, so that the inner ends of the two fan locking plates are pressed against the upper side of the positioning plates, thereby achieving reliable positioning and locking of the fan base and the fan locking seat, ensuring the reliability and stability of the cooling fan body installation. The two fan locking plates are guided outward by the channel, so that the two fan locking plates are released from the press-fit lock to the positioning plates, thereby achieving convenient unlocking of the cooling fan body. The cooling fan body is connected to the fan base only by two fan positioning shafts along the direction of the fan airflow, which does not block the cooling airflow of the cooling fan body, ensuring 100% cooling efficiency of the cooling fan body and improving cooling efficiency. The overall structure is simple, the cooling fan body is easy and flexible to disassemble and assemble, and the installation is secure and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0032] like Figure 1-10 As shown, the present invention discloses a server fan module, including a fan base 2 and a fan lock seat 3 that can be positioned and installed with a server chassis. Four ear plates 21 are provided at the four corners of the upper side of the fan base 2. The two ear plates 21 corresponding to the left and right form a pair. A fan positioning shaft 22 is positioned and installed between the two ear plates 21. The fan positioning shaft 22 can pass through the corresponding mounting holes on the lower side of the heat dissipation fan body 1 to achieve reliable positioning and installation of the heat dissipation fan body 1 and the fan base 2. A groove 310 is provided in the middle of the upper side of the fan lock seat 3. Channels communicating with the groove 310 are provided at the left and right ends of the fan lock seat 3. The channels are arranged in a left-right direction. A fan lock plate 4 that can slide left and right along the channel is provided in the channel. A boss 24 that can be embedded in the groove 310 is provided on the lower side of the fan base 2. Positioning plates 26 that can engage with the left and right fan lock plates 4 are provided on the left and right sides of the boss 24.

[0033] The cooling fan body 1 is positioned and installed on the fan base 2 through two fan positioning shafts 22, and the fan locking seat 3 is positioned and installed on the bottom plate of the server chassis. The two fan locking plates 4 are guided by the channel and pushed inward (the fan locking plate 4 on the left is pushed to the right, and the fan locking plate 4 on the right is pushed to the left), so that the inner ends of the two fan locking plates 4 are pressed against the upper side of the positioning plate 26, thereby achieving reliable positioning and locking of the fan base 2 and the fan locking seat 3, ensuring the reliability and stability of the installation of the cooling fan body 1; the two fan locking plates 4 are guided by the channel and pulled outward (the fan locking plate 4 on the left is pulled to the left, and the fan locking plate 4 on the right is pulled to the right), so that the two fan locking plates 4 are released from the press-fit lock on the positioning plate 26, thereby achieving convenient unlocking of the cooling fan body 1. The connection between the cooling fan body 1 and the fan base 2 is achieved solely through two fan positioning shafts 22 extending along the fan airflow direction, which completely prevents the cooling airflow of the cooling fan body 1 from being obstructed, thereby ensuring 100% cooling performance of the cooling fan body 1 and improving cooling efficiency. The overall structure is simple, the cooling fan body 1 is easy and flexible to assemble and disassemble, securely installed, and highly practical.

[0034] In order to ensure the reliability of the fitting installation between the heat dissipation fan body 1 and the fan base 2 , a rubber pad is provided between the fan base 2 and the heat dissipation fan body 1 .

[0035] like Figure 3 As shown, two positioning plates 23 are provided on the underside of the fan base 2, symmetrically positioned on the left and right sides of the boss 24. Positioning slots 36 are provided on the upper side of the fan lock seat 3 (above the two channels) to engage with the positioning plates 23. When the fan lock plate 4 engages with the positioning plates 26, the positioning plates 23 engage with the positioning slots 36, effectively limiting the horizontal position of the fan base 2 (cooling fan body 1), making the locking installation of the fan base 2 and the fan lock seat 3 more reliable, stable, and precise.

[0036] Tension spring hooks 38 are located on the left and right sides of the bottom surface of the groove 310. A connecting pin 44 is positioned on the underside of the fan lock plate 4 in the forward and backward directions. A tension spring 5 is connected between the connecting pin 44 and the tension spring hook 38. The tension spring 5 exerts an inward tension on both sides of the fan lock plate 4, ensuring the secure engagement and locking of the fan lock plate 4 with the positioning plate 26, and thus ensuring the secure installation of the fan base 2 and the fan lock base 3.

[0037] Two positioning slots 36 communicate with the left and right channels, respectively. A limiting protrusion 43 with upward elastic support is provided on the upper side of the fan lock plate 4. When the fan lock plate 4 is withdrawn (unlocking the positioning plate 26), the limiting protrusion 43, under the action of the upward elastic force, snaps upward into the positioning slot 36 and lifts the positioning plate 23, thereby lifting the fan base 2 upward and facilitating removal of the fan base 2. Similarly, when installing the fan base 2, the positioning plate 23 is inserted into the positioning slot 36, pressing down on the limiting protrusion 43. The tension spring 5 pulls the fan lock plate 4 inward, automatically locking the positioning plate 26 and facilitating installation of the fan base 2. The fan base 2 and the fan lock base 3 can be disassembled and assembled without tools, ensuring ease of use. Furthermore, the engagement of the limiting protrusion 43 with the positioning slot 36 limits the fan lock plate 4 to its maximum outward pull position, preventing it from slipping out of the channel and ensuring reliable operation.

[0038] Among them, such as Figure 8 As shown, the outer edge of the top of the limiting protrusion 43 has a smooth rounded corner, which effectively prevents scratches on the upper wall of the channel; the inner side wall of the limiting protrusion 43 is a vertical plane, which ensures that the limiting protrusion 43 and the positioning slot 36 can be reliably engaged and positioned under the tension of the tension spring 5.

[0039] Among them, such as Figure 7 As shown, a slide groove 37 is provided on the side wall of the channel to guide the left and right sliding of the end of the connecting pin 44. The slide groove 37 guides the left and right sliding of the end of the connecting pin 44 and limits the left and right extreme positions (when the outer wall of the slide groove 37 abuts the connecting pin 44, the limiting protrusion 43 just fits into the positioning slot 36). This ensures the accuracy, stability and reliability of the sliding of the fan lock plate 4 in the channel, effectively preventing the fan lock plate 4 from sliding too far inward under the tension of the tension spring 5 and tightly abutting the side wall of the boss 24, thereby crushing the side of the boss 24. It also prevents the fan lock plate 4 from being pulled outward and out of the channel, effectively protecting the tension spring 5 (limiting the stretching length of the tension spring 5).

[0040] like Figure 8 As shown, the fan lock plate 4 is provided with an elastic connecting plate 42, which is cut and formed integrally with the fan lock plate 4. The connecting plate 42 is embedded in the groove opened in the fan lock plate 4 and is flush with the upper surface of the fan lock plate 4. The inner end of the connecting plate 42 is connected to the groove wall, and the limiting protrusion 43 is provided at the outer end (free end) of the connecting plate 42 and protrudes upward. The connecting plate 42 has a certain elastic bending performance so that the limiting protrusion 43 can be smoothly inserted into the positioning slot 36.

[0041] The fan locking plate 4 has an open / close indicator on its upper side, and a display window 35 is provided at the top of the channel to display the open / close indicator. When the fan locking plate 4 is pulled out (when the stopper protrusion 43 engages the positioning slot 36), the open indicator is visible in the display window 35, indicating the fan is in the open state. When the fan locking plate 4 is locked to the positioning plate 26, the closed indicator is visible in the display window 35, indicating the fan is in the closed state. This provides a visual indication of the operating status and prevents misoperation.

[0042] like Figure 5-6 As shown, the upper side of the fan lock seat 3 is further provided with four limit seats 34 for limiting the position of the fan base 2. The limit seats 34 are in a right-angled structure, forming a wrap angle positioning for the four corners of the fan base 2, ensuring the accuracy and reliability of the installation of the fan base 2 and the fan lock seat 3.

[0043] The fan lock plate 4 has an upwardly curved operating portion 41 at its outer end, allowing for convenient push-pull operation of the fan lock plate 4. A support plate 46 connects the inner side of the operating portion 41 to the fan lock plate 4. The left and right ends of the fan lock seat 3 have support plate positioning slots 31 that snap fit with the support plates 46. The support plates 46 reinforce the operating portion 41 and the fan lock plate 4. When locked (when the fan lock plate 4 is engaged with the positioning plate 26), the support plates 46 snap into the support plate positioning slots 31, ensuring the compactness and stability of the locked structure.

[0044] Among them, two second support plates 45 in the left and right directions are provided at the bottom of the fan locking plate 4. The second support plates 45 are used to strengthen the structure of the fan locking plate 4 and realize sliding support in the channel, avoiding clanging and reducing sliding friction.

[0045] The fan lock base 3 comprises two split lock bases that are mounted side by side. The right split lock base has an elastic buckle 32 on its front side and a buckle slot 33 on its rear side. The left split lock base has a buckle slot 33 on its front side and an elastic buckle 32 on its rear side. These two split lock bases are mounted side by side to form a single unit, namely, the fan lock base 3. The undersides of the two split lock bases each have two opposing mounting slots 39, which are designed to engage with I-shaped nails on the server chassis. When the two split lock bases are mounted side by side, the mounting slots 39 on their undersides engage with the I-shaped nails on the server chassis, ensuring secure positioning and interlocking of the two split lock bases with the server chassis.

[0046] like Figure 3As shown, four cross first support ribs 25 are provided on the bottom surface of the boss 24, and the two first support ribs 25 in the left and right directions extend to the lower side of the positioning plate 26 at both ends to strengthen the structure of the boss 24 and the positioning plate 26, and contact with the bottom surface of the groove 310 to play a supporting role.

[0047] A relief groove 27 is provided on the bottom surface of the boss 24 for evading the I-nail on the server chassis, and a relief groove is provided in the middle of the positioning plate 26 for evading the tension spring hook 38. The structural design is reasonable and compact, and the limited space inside the server is fully utilized.

[0048] In this server fan module, the cooling fan body 1 is positioned and installed with the fan base 2 via two fan positioning shafts 22, and the fan locking seat 3 is positioned and installed with the server chassis bottom plate. The two fan locking plates 4 are guided inward by the channel and pushed inward, so that the inner ends of the two fan locking plates 4 are pressed against the upper side of the positioning plate 26, thereby achieving reliable positioning and locking of the fan base 2 and the fan locking seat 3, ensuring the reliability and stability of the installation of the cooling fan body 1. The two fan locking plates 4 are guided outward by the channel, so that the two fan locking plates 4 are released from the pressed lock on the positioning plate 26, thereby achieving convenient unlocking of the cooling fan body 1. The connection between the cooling fan body 1 and the fan base 2 is achieved only by two fan positioning shafts 22 along the direction of the fan airflow, which does not block the cooling airflow of the cooling fan body 1 at all, ensuring 100% cooling performance of the cooling fan body 1 and improving cooling efficiency. The overall structure is simple, the cooling fan body 1 is easy and flexible to disassemble and assemble, and the installation is reliable and practical.
