[0020] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Figure 1 It is a schematic diagram of the cross-sectional layout of the internal structure of an existing server, such as Figure 1 As shown, the present application uses a simplified diagram to illustrate the positional relationship between the built-in fan assembly 110 inside the server 100 and the rear optical module 120 at the rear end of the server 100. Figure 1 It can be seen that the area where the rear optical module 120 is located is far away from the built-in fan assembly 110, and the airflow of the built-in fan assembly 110 is difficult to effectively reach the surface of the rear optical module 120 for heat dissipation; at the same time, due to the limitation of the internal space of the server, there is no space near the rear optical module 120 to add enhanced heat dissipation devices.

[0022] Currently, the server 100 comes with a rear optical module 120 in a fixed position when it leaves the factory. The connector position of the rear optical module 120 is bound to the server 100. Since the connector positions of the rear optical modules 120 manufactured by other manufacturers are different, it is difficult to blindly couple the same cabinet with servers 100 manufactured by multiple server manufacturers. One server needs to be coupled and delivered with one cabinet product, which greatly limits flexibility. In addition, the heat dissipation of the rear network card module of the server 100 has the same heat dissipation difficulty as the rear optical module 120.

[0023] In response to the above problems, the present application proposes a compatible adapter device and a server cabinet that can flexibly adapt to different servers and enhance the heat dissipation performance of rear network card components or rear optical modules, which are described in detail below with reference to the accompanying drawings.

[0024] Figure 2 is a schematic diagram of the layout of the server and switching device provided by this application, such as Figure 2As shown, the present application provides an adapter device 200, including a heat dissipation adapter component 210, a connector component 220 and a fan component 230. The connector component 220 can be adjustably arranged on the heat dissipation adapter component 210 to adapt to the network interface position of servers of different models; the fan component 230 is connected to the connector component 220 to move with the connector component 220 when the connector component 220 is adjusted, so as to perform targeted heat dissipation on the rear optical module or the rear network card module of the server.

[0025] In one embodiment, the connector assembly 220 is provided with a detachable connection connector 221 to adapt to different models of servers. After the connector assembly 220 is connected and adjusted to a target position corresponding to the network interface position, the connection connector 221 is electrically connected to the server of the corresponding model to achieve server data transmission and power supply for the fan assembly 230.

[0026] The heat dissipation adapter assembly 210 has a supporting function, and is used to support the connector assembly 220 and the fan assembly 230, and can be fixed on the server cabinet. By adjusting the horizontal position of the connector assembly 220 in the heat dissipation adapter assembly 210, it can adapt to servers 100 of different manufacturers or different models of the same manufacturer, and realize the hardware decoupling of the server 100 and the server cabinet. The function of the connector assembly 220 is, on the one hand, to adjust the position of the fan assembly 230 so as to realize local heat dissipation at the rear end of the server 100, and on the other hand, to connect the rear optical module 120 or the rear network card module of the server 100 to realize the communication connection between the server 100 and the server cabinet.

[0027] The rear optical module 120 is an important component of optical fiber communication, and mainly completes the reception and transmission of optical signals, as well as the mutual conversion between optical signals and electrical signals. The rear network card module is an important hardware device of the server 100, which is used to realize data transmission between the server 100 and the network.

[0028] It can be understood that the present application aims to solve the heat dissipation problem of the rear network card and optical module of the server 100 and the network blind plug compatibility problem of servers 100 from different manufacturers. The fan assembly 230 is driven to move by the connector assembly 220 to adapt to different types of servers 100 from different manufacturers, and to dissipate heat for the rear optical module or rear network card module of the server 100. The decoupling of the server 100 and the server cabinet is achieved through the movable connector assembly 220, which improves the delivery flexibility. The servers 100 manufactured by different manufacturers can be blindly plugged into the server cabinet to solve the one-to-one binding problem between the existing server cabinet and the server 100. At the same time, the heat dissipation performance of the rear network card module and the rear optical module 120 of the server 100 is enhanced, the heat dissipation bottleneck problem is solved, the fan speed and the overall power consumption are reduced, and there is no need to increase the fan speed to improve the heat dissipation performance, which will not increase the server power consumption, which is beneficial to improving the optical module power and the network transmission rate.

[0029] On the basis of the above embodiment, as an optional embodiment, the heat dissipation adapter assembly 210 is provided with a slide groove 211, the connector assembly 220 includes a slider, the slider is slidably arranged in the slide groove, and the fan assembly 230 is connected to the slider so as to follow the slider to move along the slide groove during adjustment. Specifically, the slide groove 211 can be in the shape of a long strip, extending along the horizontal direction of the heat dissipation adapter assembly 210, and the connector assembly 220 can drive the fan assembly 230 to move from the left side of the heat dissipation adapter assembly 210 to the right side of the heat dissipation adapter assembly 210, or from the right side of the heat dissipation adapter assembly 210 to the left side of the heat dissipation adapter assembly 210, until it moves to a position corresponding to the rear optical module 120 or the rear network card module of the server 100, so as to facilitate blind insertion of the connector assembly 220 with the rear optical module 120 or the rear network card module.

[0030] It can be understood that the present application provides a slide groove 211 on the heat dissipation adapter assembly 210 and a slider on the joint assembly 220 to facilitate the movement of the joint assembly 220 relative to the heat dissipation adapter assembly 210, thereby further improving the flexibility of the server cabinet.

In another embodiment, the heat dissipation adapter assembly 210 can be composed of a rectangular metal box, and the connection joint 221 faces the rear optical module 120 or the rear network card module of the server 100. On the basis that the heat dissipation adapter assembly 210 is composed of a rectangular metal box, a cavity for routing is provided inside the heat dissipation adapter assembly 210 to ensure that the cables required for network transmission pass through. In any of the above embodiments, the slider is provided at the rear end of the connector assembly 220 .

[0032] On the basis of the above-mentioned embodiment, as an optional embodiment, the heat dissipation adapter assembly 210 includes a heat dissipation adapter body and a heat dissipation adapter base plate vertically arranged with respect to the heat dissipation adapter body, and the slide groove 211 is arranged on the heat dissipation adapter base plate. In this embodiment, the heat dissipation adapter assembly 210 is L-shaped as a whole, and the heat dissipation adapter body can be composed of a metal plate, and can be detachably fixed to the server cabinet by means of screws or the like. The heat dissipation adapter base plate can also be composed of a metal plate, and is used to carry the connector assembly 220 and the fan assembly 230. In this embodiment, the slider is arranged at the lower end of the connector assembly 220. On the basis that the heat dissipation adapter body can be composed of a metal plate, the outside of the heat dissipation adapter assembly 210 is provided with an opening for wiring to ensure that the cables required for network transmission can pass through.

[0033] It is understandable that the present application provides a structural configuration scheme for the heat dissipation adapter assembly 210, which can allow the connector assembly 220 to move in at least one direction, flexibly adapt to different servers 100, and perform local heat dissipation on the back end of the server 100.

[0034] On the basis of the above embodiment, as an optional embodiment, the adapter 200 provided by the present application further includes a fastening assembly (not shown in the figure), which is detachably connected to the connector assembly 220 and is used to fix the connector assembly 220 on the heat dissipation adapter assembly 210 after the connector assembly 220 is adjusted to a target position corresponding to the network interface position. The fastening assembly is used to fix the connector assembly 220 after the connector assembly 220 and the fan assembly 230 are moved to a position corresponding to the rear optical module or the rear network card module of the server 100, and the fastening assembly can be composed of bolts and nuts.

[0035] It can be understood that the present application can improve the stability of the joint assembly 220 and the fan assembly 230 by providing a fastening assembly.

[0036] Based on the above embodiments, as an optional embodiment, the connection connector 221 includes a first connection connector and a second connection connector, the first connection connector is used to connect to the rear optical module 120 or the rear network card module, and the second connection connector is used to connect to the server 100 to provide power for the fan assembly 230.

[0037] The first connection connector may include MT blind connector, LC blind connector and SC blind connector, etc. MT blind connector: MT (Mechanical Transfer-Registered Jack) connector is a multi-core fiber optic connector that uses a multi-core fiber optic wiring system for high-density fiber optic connection. It is usually used for MPO / MTP fiber optic connectors and can achieve fast blind plug connection of multi-core optical fibers. LC (Lucent Connector) blind connectors are usually used for single-mode or multi-mode fiber optic connections. They have the advantages of miniaturization, high density and low insertion loss, and are suitable for the connection of optical modules. SC (Subscriber Connector) blind connectors are also commonly used for single-mode or multi-mode fiber optic connections. They have the characteristics of standardized interfaces and simple operation, and are suitable for blind plug connections of optical modules.

[0038] The second connection connector is a fan blind plug connector, such as a 3-pin fan connector or a 4-pin fan connector. The 3-pin fan connector is usually used to connect a standard fan, one of which is responsible for the power supply of the fan, and the other two are responsible for transmitting the fan speed signal. 4-pin fan connector (PWM fan connector): In addition to the functions of a 3-pin fan connector, it also includes a PWM (pulse width modulation) controller, which can adjust the fan speed by controlling the current through the motherboard. By setting a fan blind plug connector, it is convenient for users to quickly install and replace fans without worrying about damage caused by reverse or crooked insertion. In an embodiment of the present application, the fan assembly 230 is powered by the server 100.

[0039] It can be understood that the present application provides a configuration scheme of the connection connector 221, which ensures network transmission by setting a first connection connector and a second connection connector, and can also adjust the wind speed of the fan assembly 230 to achieve low-power heat dissipation.
