- a second aspect of the embodiments of the present application provides a power supply rack, including:
- a power module with a transformer configured to convert 220V AC from the input line to 12V DC;
- At least one fan with the air outlet facing toward the power rack where the module is located;
- the first copper bar has a U-shaped structure and is arranged half-surrounding the fan;
- the second copper bar is electrically connected to both ends of the first copper bar, and the combination of the first copper bar and the second copper bar constitutes a closed loop completely surrounding the fan.
- the fan is a Hall elementless fan.
- the first copper bar is electrically connected to the input line on one side of the U-shaped structure, and is electrically connected to the output line on the other side of the U-shaped structure; the second copper bar is shunted from one side of the U-shaped structure. current flowing from one side to the other.
- the first copper bar is electrically connected to the input line via a transformer.

- FIG. 2 is a structural diagram of the heat dissipation and power supply module provided by the application without a second copper bar;
- FIG. 3 is a structural diagram of a heat dissipation and power supply module provided by the present application with a second copper bar.
- FIG. 1 shows a schematic flowchart of the heat dissipation and power supply module provided by the present application.
- the cooling and power supply module includes:
- At least one fan 1 with the air outlet facing toward the power rack where the module is located;
- the first copper bar 2 has a U-shaped structure and is arranged semi-surrounding the fan 1;
- the second copper bar 3 is electrically connected to both ends of the first copper bar 2 , and the combination of the first copper bar 2 and the second copper bar 3 constitutes a closed loop completely surrounding the fan 1 .

- key components such as the motor of the fan 1 are still driven electromagnetically, so the fan 1 without a Hall element is still inevitably affected by the Hall effect to a certain extent.
- the embodiments of the present application also start to reduce the actual magnetic induction intensity to reduce the influence of the Hall effect.
- a shunt branch is added to the U-shaped copper bar to form a ring-shaped closed copper bar, so that the current passing through each side is reduced by half, and the magnetic induction intensity is correspondingly reduced by half.
