[0021] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0022] like Figures 1 to 3 As shown, a fan heat dissipation module provided by an embodiment of the present invention includes a panel 1, a control board 3 and a plurality of fans 2. The plurality of fans 2 are mounted on the panel 1, and the control board 3 can also be mounted on the panel 1. The three are integrated into a whole, which is convenient for replacement and saves costs. The plurality of fans 2 are controlled by PWM signals controlled by the control board 3 and a speed signal FG is fed back to the control unit in real time. Specifically, the control board 3 is provided with a plurality of fan connectors 7 for connecting with the plurality of fans 2. The number of fan connectors 7 is not less than the number of fans 2, so as to facilitate the subsequent addition of fans 2. In this embodiment, the number of fans 2 is three, and the number of fan connectors 7 is also three.

[0023] The three fans 2 are arranged in a longitudinal arrangement, a transverse arrangement or a stacked arrangement. In this embodiment, the transverse arrangement is used as an example.

[0024] The control board 3 also includes a single-chip microcomputer 4 and an optocoupler isolation circuit 10. The output end of the fan connector 7 is connected to the input end of the optocoupler isolation circuit 10. The output end of the optocoupler isolation circuit 10 is connected to the input end of the single-chip microcomputer 4. The output end of the single-chip microcomputer 4 is connected to the signal connector 5.

[0025] The fan cooling module of this embodiment adopts 48V fan power supply and 3.3V weak current control power supply. The control board 3 has a signal connector 5 and a power connector 6. The signal connector 5 is used to receive the control signal, and the power connector 6 is used to receive the power supply. The 48V high voltage input enters from the power connector 6, and the 3.3V weak current part enters from the signal connector 5. The interactive part in the middle is coupled by a photoelectric tube. The control signal is transmitted from the backplane to the single-chip microcomputer 4, and is converted by the local control strategy to control and access the fan module. The three groups of fan modules are independent of each other, and obtain 48V electricity and PWM signals from the control board 3 through independent connectors and feed back FG signals to the control unit.

[0026] This module supports single-fan mode, dual-fan mode, and triple-fan mode. Dynamic cooling strategies can be set according to different scenarios. For example, single-fan mode is used in low-power scenarios, while triple-fan mode is used in high-power scenarios.

[0027] This module supports a maximum speed of 15000 RPM for all fans in three-fan mode, and simultaneously monitors the operating status and speed of the three fans 2. The module control unit will report the status of the cooling module in real time and dynamically adjust the speed of fan 2 according to the cooling strategy issued by the main control end. At 100% speed, the air volume can reach 423 FCM.

[0028] The 48V power input end has a hot-swap circuit 11. The input end of the hot-swap circuit 11 is connected to the power connector 6, and the output end is connected to the fan connector 7. This supports hot-swap operation of the heat dissipation module in the whole machine, making it easy to replace the heat dissipation module.

[0029] An indicator light is mounted on the panel 1, and an indicator light connector 8 connected to the indicator light is provided on the control board 3;

[0030] In addition, to facilitate debugging, a debugging interface 9 is also provided on the control board 3 .
