[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] This utility model provides a server cooling fan that solves the technical problem that existing server cooling fans are often tested without a fan cover, which can lead to injury to test personnel or malfunction due to the fan sucking in foreign objects.

[0033] See Figure 1As shown in the figure, this utility model embodiment provides a server cooling fan, the fan including: fan body 1, fan protective cover 2 and fan connector 3.

[0034] The fan body 1 generally includes a motor and fan blades. The motor rotates under the drive, causing the fan blades to rotate and providing heat dissipation for the server. The fan protective cover 2 is detachably connected to the fan body 1.

[0035] The fan connector 3 includes a separate first connection part 31 and a second connection part 32. The first connection part 31 is provided with a grounding pin and an in-situ detection pin. The control pin of the second connection part 32 is connected to the fan body 1 through a wire. The first connection part 31 and the second connection part 32 are fitted together to form an integral part and are detachably connected to the fan protective cover 2.

[0036] See Figure 1 and Figure 2 As shown, in this embodiment of the invention, the fan connector 3 is designed as a separate first connecting part 31 and a second connecting part 32. The second connecting part 32 is connected to the fan body 1 via a wire. Only when the separate first connecting part 31 and the second connecting part 32 are fitted together to form the fan connector 3 and installed on the fan protective cover 2, and then connected to the corresponding interface on the server, can the server's Complex Programmable Logic Device (CPLD) detect the presence of the fan, thus enabling subsequent server cooling fan testing (the second connecting part 32 alone lacks a presence detection pin, and even if connected to the server's interface, testing cannot be performed). This avoids the situation where the server cooling fan is tested without a fan protective cover, and also prevents injury to test personnel or the server cooling fan from sucking in foreign objects. This embodiment of the invention hardly changes the original structural design of the server cooling fan, is simple to implement, and is easy to promote and apply.

[0037] As an optional implementation, in one embodiment of the utility model, when the fan body 1 is a dual-rotor fan, the fan connector 3 is an N-pin fan connector. The first connection part 31 includes a #N-1 pin and a #N pin, wherein the #N-1 pin is a ground pin, and the #N pin is an in-situ detection pin. The in-situ detection pin is shorted to the ground pin to facilitate detection by the server's complex programmable logic devices. N is a positive integer. Taking N=8 as an example, see [link to relevant documentation]. Figure 3As shown, if the first connecting part 31 is not fitted with the second connecting part 32 to form the fan connector 3, and only the second connecting part 32 is connected to the server, the server's complex programmable logic device will not detect the fan's presence, and therefore will not output a FAN_PWM control signal, nor will it turn on the fan's power, and will not perform a fan test. Additionally, a server page alarm and a red indicator light on the server's front panel will simultaneously display a fault. It should be noted that, depending on the value of N, when the fan body 1 is a dual-rotor fan, the fan connector 3 can also be a fan connector with different pin counts, such as 10 pins or 12 pins, as long as two pins are selected from all the pins and placed in the first connecting part 31.

[0038] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 4 As shown, when the fan body 1 is a single rotor, the fan connector 3 is an M-pin fan connector. The fan connector 3 has pins #M-1 and #M, where #M is the ground pin and #M-1 is the presence detection pin. The presence detection pin is shorted to the ground pin for easy detection by the server's complex programmable logic device (CPLD). M is a positive integer. Similarly, if the first connection part 31 is not attached to the second connection part 32 to form the fan connector 3, and only the second connection part 32 is connected to the server, the server's CPLD will not detect the fan's presence, and therefore will not output a FAN_PWM control signal. Simultaneously, the fan power will not be turned on, and no fan test will be performed. Additionally, a server page alarm and a red light on the server front panel will simultaneously indicate a fault. The electronic circuitry, CPLD code, and mechanical structure of the entire technical solution can be easily implemented. Similarly, it should be noted that, depending on the value of M, when the fan body 1 is a single rotor, the fan connector 3 can also be a fan connector with other different pins, as long as two pins are selected from all the pins and set in the first connection part 31.

[0039] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the fan protective cover 2 includes a front frame cover 21, which is detachably connected to the fan body 1. The front frame cover 21 provides protection on the front side of the fan body 1. Optionally, the front frame cover 21 and the fan body 1 are detachably connected via a snap-fit ​​connection structure, facilitating installation and removal.

[0040] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1As shown, the fan protective cover 2 includes a rear frame cover 22, which is detachably connected to the fan body 1. The rear frame cover 22 provides protection to the rear side of the fan body 1. Optionally, the front frame cover 21 is detachably connected to the fan body 1 via a snap-fit ​​connection structure, facilitating installation and removal.

[0041] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the fan also includes a connector mounting base 4, which is connected to the rear frame cover 22. The fan connector 3 is detachably connected to the connector mounting base 4, and the fan connector 3 can be conveniently installed on the rear frame cover 22 through the connector mounting base 4.

[0042] Further, see Figure 1 As shown, the lower end of the connector mounting base 4 is provided with a snap fastener 41 that is detachable from the fan connector 3. The snap fastener 41 facilitates the mounting of the fan connector 3 onto the connector mounting base 4, or facilitates the removal of the fan connector 3 from the connector mounting base 4.

[0043] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, both the first connecting part 31 and the second connecting part 32 are provided with limiting protrusions 311 that contact the buckle 41. The limiting protrusions 311 can restrict the relative movement of the first connecting part 31 and the second connecting part 32 with the buckle 41, ensuring the reliability of the connection between the first connecting part 31 and the second connecting part 32.

[0044] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the connector mounting base 4 is provided with a wire fixing slot 42. The wire fixing slot 42 facilitates the fixing of the wires connecting the first connecting part 31 to the fan protective cover 2 and the wires connecting the second connecting part 32 to the fan body 1, preventing the wires from loosening and ensuring the reliability of the connection.

[0045] This utility model embodiment also provides a server, including the aforementioned server cooling fan.

[0046] The server in this embodiment of the invention features a server cooling fan comprising a fan body, a fan protective cover, and a fan connector. The fan connector is designed with separate first and second connecting parts. Only by fitting these two parts together to form the fan connector and installing it on the fan protective cover, and then connecting it to the corresponding interface on the server, can the server's complex programmable logic devices detect the fan's presence. This allows for subsequent testing of the server cooling fan, preventing testing without the fan protective cover and avoiding injury to test personnel or the inhalation of foreign objects by the cooling fan. This embodiment of the invention barely alters the original structural design of the server cooling fan, making it simple to implement and easy to promote and apply.
