[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0025] Because traditional cooling fans are fixed inside the equipment and form an integral structure with it, they cannot be directly replaced or maintained from the outside. It is necessary to disconnect the power to the equipment and then disassemble it to perform the corresponding operations on the cooling fan, which is inconvenient.

[0026] Therefore, this embodiment provides a hot-swappable fan assembly. The fan, as a separate module, can be safely removed or inserted while the device is running, facilitating replacement or maintenance.

[0027] Please see Figure 1The hot-swappable fan assembly provided in this embodiment includes a mounting base 1, a fan 2, and a plug-in unit. The fan 2 is mounted on the mounting base 1, the mounting base 1 is detachably connected to the air outlet of the device, and the plug-in unit is used to enable plugging and unplugging between the mounting base 1 and the device, so as to insert the fan 2 into the air outlet or pull it out of the air outlet.

[0028] For details, please continue reading Figure 1 The mounting base 1 includes a support plate 11 and a back plate 12. The support plate 11 and the back plate 12 are connected in an L-shape. The fan 2 is placed on the support plate 11. Furthermore, the fan 2 is fixed to the back plate 12, and the middle area of ​​the back plate 12 is provided with an air outlet. The air outlet is directly opposite the fan 2. When the fan 2 is turned on, the heat inside the device is drawn out through the air outlet.

[0029] Preferably, the mounting base 1 further includes two spaced baffles 13 for limiting the fan 2 and preventing the fan 2 from shaking. Specifically, the baffles 13 are trapezoidal, with the bottom of the baffles 13 connected to the support plate 11 and the side of the baffles 13 connected to the back plate 12. The fan 2 is sandwiched between the two baffles 13, and the baffles 13 limit the movement of the fan 2.

[0030] More preferably, the mounting base 1 further includes a sealing plate 14 for further limiting the fan 2. Specifically, the sealing plate 14 is connected to the side of the back plate 12 near the support plate 11 and is disposed on the top of the back plate 12 so that it abuts against the top of the fan 2 to limit the fan 2.

[0031] In this embodiment, the back plate 12 is detachably connected to the device. For example, a plurality of mounting holes are spaced circumferentially on the back plate 12, and corresponding screw holes are formed on the device housing. Preferably, the mounting holes are located on the side of the back plate 12, and the screw holes are formed around the air outlet. Connecting screws 3 are passed through the mounting holes one by one and screwed into the corresponding screw holes, thereby fixing the back plate 12 to the air outlet of the device, thus securing the mounting base 1 to the device.

[0032] To facilitate the operator's tightening, this embodiment provides a connecting screw 3 including a handle and a threaded part. The threaded part is used to pass through the mounting hole and screw the device. Furthermore, the handle and the threaded part are coaxially connected. The size of the handle is larger than that of the threaded part. The handle is provided with anti-slip texture to facilitate the operator's application of force to tighten.

[0033] For example, the plug-in unit includes a male connector assembly and a female connector assembly, which are plugged into each other. The female connector assembly is mounted on the mounting base 1, and the male connector assembly is installed inside the device. During use, pushing the mounting base 1 towards the device along a first direction causes the female connector assembly to plug into the male connector assembly, thus securing the fan 2 to the device. Tightening the connecting screws 3 releases the screw connection between the backplate 12 and the device. Pulling the mounting base 1 away from the device along the first direction causes the female connector assembly to detach from the male connector assembly. The fan 2, as a separate module, can be safely removed while the device is running, facilitating replacement or maintenance. It should be noted that the first direction refers to the thickness direction of the fan 2.

[0034] Specifically, the female connector assembly is mounted on the tray 11, and the fan 2 is located between the back plate 12 and the female connector assembly.

[0035] Optionally, please refer to Figure 1 The female head assembly includes a female head 4 and a female mounting base 5. The female mounting base 5 is fixed to the fixed base 1, and the female head 4 is disposed on the female mounting base 5 along a first direction.

[0036] For example, the bottom of the female mounting base 5 is screwed to the support plate 11, and a through groove is opened in the middle area of ​​the female mounting base 5, through which the female head 4 passes and is fixed.

[0037] Optionally, please refer to Figure 1 The male connector assembly includes a male connector 6 and a male mounting base 7. The male mounting base 7 is fixed inside the equipment, and the male connector 6 is disposed on the male mounting base 7 along a first direction.

[0038] For example, the bottom of the male mounting base 7 is screwed into the interior of the device, and the male head 6 is located in the middle area of ​​the male mounting base 7.

[0039] To improve the insertion strength between the male connector 6 and the female connector 4, this embodiment provides several recesses at intervals on the end of the male connector 6 near the female connector 4, and several protrusions at intervals on the end of the female connector 4 near the male connector 6. The protrusions can be inserted into the recesses one by one, which not only improves the insertion strength between the male connector 6 and the female connector 4, but also ensures that the female connector 4 is accurately inserted into the male connector 6.

[0040] In other feasible embodiments, a handle can also be provided on the side of the back plate 12 away from the tray 11, so that the operator can hold the handle and push and pull the fixed seat 1 in the first direction, thereby improving the ease of use.

[0041] With the above settings, the hot-swappable fan assembly provided in this embodiment can be used by pushing the mounting base 1 towards the device along the first direction, causing the female head 4 to approach the male head 6. Several protrusions are inserted into several recesses one by one, and then the connecting screws 3 are passed through the mounting holes and screwed into the corresponding screw holes to fix the back plate 12 to the air outlet of the device, thus fixing the fan 2 to the device. Tightening the connecting screws 3 releases the screw connection between the back plate 12 and the device. Pulling the mounting base 1 away from the device along the first direction causes the female head 4 to detach from the male head 6, and the fan 2 can be safely pulled out as a separate module while the device is running, making it convenient to replace or maintain the fan 2.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
