[0050] Specific implementation of the wireless network card with anti-signal interference:

[0051] The wireless network card includes an outer shell 1 and an internal component 2. The outer shell 1 is a closed shell for protecting the internal component 2 from the influence of the external environment. The internal component 2 includes a USB plug connector 21, a positioning seat 23, a circuit board 22 and a side connecting frame 24. Air inlets 12 are provided on the left and right sides of the bottom end of the outer shell 1 to allow air to enter the interior for cooling. A filter component 4 with a U-shaped docking piece 41 is docked at the bottom end of the outer shell 1 to filter the incoming air. A heat dissipation component 3 is installed on the front and rear shell walls inside the outer shell 1, which is composed of a plurality of heat dissipation fins 31 to improve the heat dissipation efficiency. A heat dissipation fan 6 is installed near the top of the outer shell 1 to promote air circulation and further heat dissipation. A shielding layer 5 is embedded inside the inner shell wall of the outer shell 1, which is composed of a first shielding cover 51, an adhesive layer 52 and a second shielding cover 53 to reduce electromagnetic interference.

[0052] Specific implementation of the internal component 2:

[0053] The USB plug connector 21 is mounted on the top of the outer shell 1 for connecting to a computer or other device. The positioning seat 23 is mounted on the bottom of the outer shell 1 for fixing the circuit board 22. The circuit board 22 is located on the top of the positioning seat 23 and has various electronic components and connection circuits. The side connecting frame 24 connects the circuit board 22 and the USB plug connector 21 to ensure the electrical connection between them. The heat dissipation fan 6 is located inside the space between the circuit board 22 and the USB plug connector 21 to help dissipate heat.

[0054] Specific implementation of the heat dissipation component 3:

[0055] The heat dissipation assembly 3 is composed of vertically distributed heat dissipation fins 31, which can increase the heat dissipation area and improve the heat dissipation efficiency. The bottom end of each heat dissipation fin 31 is bent and tilted toward the same side and toward the air inlet 12 on the same side, which can better guide the air flow and thus improve the heat dissipation effect.

[0056] Specific implementation of the filter assembly 4:

[0057] The filter assembly 4 includes a U-shaped docking piece 41, a filter core 42 and a magnetic sheet 43. The U-shaped docking piece 41 is clamped at the bottom end of the outer shell 1, and the filter core 42 is located on the left and right sides of the U-shaped docking piece 41 to filter impurities in the air. The magnetic sheet 43 is located at the top of the U-shaped docking piece 41 to fix the filter assembly 4. When the filter cores 42 on both sides are blocked, the entire U-shaped docking piece 41 can be pulled away from the bottom end of the outer shell 1.

[0058] Specific implementation of the shielding layer 5:

[0059] The shielding layer 5 comprises a first shielding cover 51, an adhesive layer 52 and a second shielding cover 53. The first shielding cover 51 is embedded in the inner wall of the outer shell 1, the second shielding cover 53 is located inside the first shielding cover 51, and the adhesive layer 52 is located between the two to fix the two shielding covers.

[0060] Specific implementation of the heat dissipation hole 11 and the protective cover 7:

[0061] The heat dissipation hole 11 is located at the back side of the top of the outer shell 1 and is connected to the heat dissipation fan 6 so that hot air can be discharged. The protective cover 7 is installed at the top of the outer shell 1 to protect the heat dissipation hole 11 from dust and debris.

[0062] How it works

[0063] Air entry: Air first enters through the air inlet 12 provided at the bottom end of the outer shell 1.

[0064] Air filtration: The incoming air will first pass through the filter assembly 4 located at the bottom of the housing to filter out dust and impurities in the air.

[0065] The heat dissipation fins guide the air flow: after the clean air enters, it will be guided by the internal heat dissipation component 3, thereby realizing the rapid heat dissipation operation of the central circuit board 22.

[0066] The cooling fan enhances air circulation: the air is continuously pumped to the cooling fan 6 and discharged at the cooling hole 11 .

[0067] Protective measures: In order to ensure that the heat dissipation holes 11 are not blocked by external dust and debris, a protective cover 7 is installed. This cover not only prevents the entry of foreign matter, but also protects the long-term performance and efficiency of the cooling fan and the heat dissipation holes.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
