[0021] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please see Figures 1 to 5 This utility model discloses a cooling device that can be hot-swapped to a switch, comprising:

[0023] The bracket 1 includes an inner end 11 and an outer end 12, and the outer end 12 is provided with a fan 2.

[0024] A connection plate 3 is disposed at the inner end 11. The connection plate 3 is provided with a plug-in interface CON1 and a connection circuit 32. The plug-in interface CON1 is pluggably connected to the plug slot of the switch. The plug-in interface CON1 includes a first connection end 311, a second connection end 312, a third connection end 313 and a fourth connection end 314. The first connection end 311 is electrically connected to the fan 2. The fan 2 is used to output an operation signal through the first connection end 311. The connection circuit 32 is connected to the second connection end 312 and the third connection end 313 respectively. The connection circuit 32 is used to receive a power supply signal through the second connection end 312 and output a connection signal through the third connection end 313. The switch is used to send a working signal or a stop signal to the fourth connection end 314 according to the received connection signal and operation signal.

[0025] Status display module 4 is mounted on bracket 1 and electrically connected to fourth connection terminal 314. Status display module 4 includes display terminal 40, which is located on outer terminal 12. Status display module 4 is used to display working information or stopping information through display terminal 40 according to the received working signal or stopping signal.

[0026] This invention enables the fan 2 to be pluggably connected to the switch and allows for real-time monitoring of the fan 2's operating status by setting a connecting plate 3 and a status display module 4. The connecting plate 3 and the fan 2 are respectively located at the inner end 11 and the outer end 12 of the bracket 1. The connecting plate 3 is provided with a connection circuit 32 and a pluggable interface CON1 that can be plugged into the switch's plug slot. The pluggable interface CON1 includes a first connection end 311, a second connection end 312, a third connection end 313, and a fourth connection end 314. The fan 2 outputs an operating signal to the switch through the first connection end 311. After receiving the power supply signal through the second connection end 312, the connection circuit 32 outputs a connection signal to the switch through the third connection end 313. Based on the connection signal and the operating signal, the switch outputs a working signal or a stop signal to the status display module 4 through the fourth connection end 314, so that the status display module 4 displays working information or stop information through the display end 40. This facilitates timely detection and replacement of faulty fans 2, helps maintain continuous heat dissipation from the cooling device, and effectively avoids the problem of reduced working efficiency due to overheating of the switch.

[0027] Specifically, in this embodiment, the plug-in interface CON1 is a gold finger interface. The cooling device is hot-plugged into the switch of the data exchange center through the gold finger interface, so that the switch can transmit power supply signals, communication signals and control signals to the cooling device. It is equipped with 10 PIN T and 10 PIN B to realize the electrical connection between the switch and the connection board 3. Among them, PIN 5T-6T of the plug-in interface CON1 forms the second connection terminal 312, and PIN 2B of the plug-in interface CON1 forms the third connection terminal 313. When the plug-in interface CON1 of the connection board 3 is inserted into the plug slot of the switch, the switch outputs a 3.3V voltage signal to the connection board 3 through the second connection terminal 312. This signal is formed into a connection signal through the connection circuit 32 and output to the switch through the third connection terminal 313. Therefore, after the plug-in interface CON1 of the cooling device is inserted into the switch, the switch can recognize that the cooling device is in place.

[0028] See Figures 1 to 5 The first connection terminal 311 includes an input pin 3111 and an output pin 3112. The fan 2 includes an FG pin 21 and a PWM pin 22. The input pin 3111 is connected to the FG pin 21. The fan 2 outputs a speed signal (FG value) to the switch through the FG pin 21 and the input pin 3111. The output pin 3112 is connected to the PWM pin 22. The switch outputs a speed control signal to the fan 2 through the output pin 3112 and the PWM pin 22 to adjust the speed of the fan 2.

[0029] Furthermore, the connecting plate 3 is provided with a welding hole 33 that is electrically connected to the first connecting end 311, and the fan 2 includes a connector J1, which is welded to the welding hole 33.

[0030] Specifically, in this embodiment, PIN3 and PIN4 of connector J1 are formed as FG pin 21 and PWM pin 22, respectively, and PIN3B and PIN9T of plug-in interface CON1 are formed as input pin 3111 and output pin 3112, respectively. The switch determines the actual working status and working speed of fan 2 based on the speed signal output by fan 2, so as to control the status display module 4 and output the corresponding PWM signal to adjust and control the speed of fan 2.

[0031] Specifically, in this embodiment, the welding holes 33 on the connecting plate 3 are adapted to connect with connectors J1 of different types of fans 2. With the pluggable interface CON1, different types of fans 2 can be replaced according to the actual situation. For example, a cooling device with B2F (Back to Front) and F2B (Front to Back) fan modules can be installed, thereby realizing the cooling of the switch by using fans 2 with different directions, effectively improving the heat dissipation effect of the switch.

[0032] Furthermore, the first connection terminal 311 includes a second power supply pin 3113, and the fan 2 includes a VCC pin 23. The second power supply pin 3113 is connected to the VCC pin 23, and the switch provides 12V voltage to the fan 2 through the second power supply pin 3113 and the VCC pin 23.

[0033] Specifically, in this embodiment, PIN1 of connector J1 is formed as VCC pin 23, and PIN1T-4T of plug-in interface CON1 is formed as second power supply pin 3113. In addition, PIN7T-8T, 4B and 7B-10B of plug-in interface CON1 are also connected to ground GND together with the connecting board 3 to form a loop.

[0034] See Figures 1 to 5 The second connection terminal 312 includes a first power supply pin 3121, the fourth connection terminal 314 includes a first control pin 3141 and a second control pin 3142, the status display module 4 includes a first indicator light 41 and a second indicator light 42, the input terminals of the first indicator light 41 and the second indicator light 42 are connected to the first power supply pin 3121, and the switch is used to control the first control pin 3141 to connect with the output terminal of the first indicator light 41 or to control the second control pin 3142 to connect with the output terminal of the second indicator light 42, so that the first indicator light 41 or the second indicator light 42 is lit.

[0035] The aforementioned first indicator light 41 and second indicator light 42 facilitate direct location of the specific fan 2, and allow for intuitive inspection of the working status of the fan 2 through the illumination of the indicator lights during equipment operation. This helps determine if the fan 2 is damaged, enabling timely replacement of any malfunctioning fan 2 and maintaining continuous heat dissipation of the switch.

[0036] Specifically, in this embodiment, PIN 10T and PIN 1B of the plug-in interface CON1 are respectively formed as the first control pin 3141 and the second control pin 3142. PIN 3 and PIN 4 of the status display module 4 are respectively formed as the output terminals of the first indicator light 41 and the second indicator light 42. The first color light displayed by the first indicator light 41 forms the working information, and the second color light displayed by the second indicator light 42, which is different from the first color light, forms the stop information. The switch performs logical processing based on the received connection signal indicating that the cooling device has been plugged into the switch and the speed signal output by the fan 2 to determine the working status of the fan 2. Then, based on the determined working status, it controls the first indicator light 41 or the second indicator light 42 to light up, so as to intuitively display the working status of the fan 2 through the working information or the stop information. Therefore, when the fan 2 malfunctions and cannot work normally, the switch controls the status display module 4 to display the stop information to prompt that the corresponding cooling device needs to be replaced, but it is not limited to this.

[0037] Specifically, in this embodiment, PIN1 and PIN2 of the status display module 4 are connected to PIN5T-6T of the plug-in interface CON1 to receive the 3.3V operating voltage provided by the switch to the first indicator 41 and the second indicator 42 through the connection board 3.

[0038] See Figures 1 to 5 The status display module 4 also includes a light guide column 43, one end of which is correspondingly set with the first display light 41 and the second display light 42, and the other end extends to the outer end 12 and forms a display end 40.

[0039] Specifically, in this embodiment, the first indicator light 41 and the second indicator light 42 are disposed at the inner end 11 of the bracket 1, and the light displayed by the first indicator light 41 and the second indicator light 42 is guided to the outer end 12 of the bracket 1 by the light guide column 43, so as to intuitively detect the working status of the fan 2 in the cooling device from the outer end 12 of the bracket 1.

[0040] See Figures 1 to 5 The plug-in interface CON1 is also provided with a fifth connection terminal 315. The connection board 3 is provided with a memory U1. The memory U1 is electrically connected to the fifth connection terminal 315. The switch reads the version information and model information of the fan 2 stored in the memory U1 through the fifth connection terminal 315.

[0041] Specifically, in this embodiment, the memory U1 is an EEPROM memory chip BL24C64A. Pins 5B and 6B of the plug-in interface CON1 are formed as the fifth connection terminal 315 and are connected to pins 5 and 6 of the memory U1 respectively to realize the I2C connection between the switch and the memory U1. By accessing and reading the fan information inside the memory U1, the production information of the fan 2 can be checked later.

[0042] Specifically, in this embodiment, PIN8 of memory U1 is also connected to PINs 5T-6T of plug-in interface CON1 to receive the 3.3V operating voltage provided by the switch to memory U1 through connection board 3.

[0043] Please see Figures 1 to 5 This utility model discloses a switch, which includes a switch body, a mounting slot, a plug slot, and a cooling device that can be hot-swapped to the switch as described above, with the plug-in interface CON1 of the cooling device plugged into the plug slot.

[0044] Specifically, in this embodiment, the outer end 12 of the bracket 1 is provided with a handle 121 to facilitate the replacement of the entire cooling device in the switch by plugging and unplugging.

[0045] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
