Description

Technical Field

[0001] This utility model relates to the field of wireless network card technology, specifically a heat dissipation structure for a wireless network card with a dustproof mesh. Background Technology

[0002] With the rapid development of wireless communication technology, wireless network cards (NICs), as core components for connecting terminal devices to the network, directly impact user experience in terms of performance and stability. However, wireless NICs generate a significant amount of heat during high-load operation. Insufficient heat dissipation can lead to increased chip temperature, resulting in performance degradation, signal delays, and even hardware damage. Therefore, efficient heat dissipation design has become a key direction for optimizing the structure of wireless NICs.

[0003] Traditional wireless network cards (NICs) rely heavily on passive cooling solutions, such as ventilation holes in the casing or the addition of heat sinks. However, these methods have limited cooling efficiency and cannot meet the continuous cooling requirements of high-performance NICs. Some improvements attempt to introduce miniature fans to enhance active cooling, but due to the compact size of wireless NICs, fan installation space is limited. Furthermore, during long-term operation, dust can easily enter the casing through the ventilation holes, accumulating on the circuit board or fan blades. This not only reduces cooling efficiency but may also cause fan jamming or short circuits. In addition, existing dust filters are mostly fixed with adhesive or clips, which are inconvenient to install and remove and lack sufficient sealing, allowing dust to seep in through gaps and affecting the dustproof effect.

[0004] In terms of heat dissipation vent design, traditional ventilation holes are mostly straight-through or simply flared, resulting in low air intake efficiency and dust accumulation on the inner walls of the vents, leading to airflow obstruction. Simultaneously, exhaust vents lack airflow guidance design, hindering hot air exhaust and potentially creating eddies, further weakening heat dissipation performance. Furthermore, existing casing structures typically use bolts to directly lock the upper and lower shells, resulting in low assembly efficiency and the accumulation of tolerances at the joints, leading to inadequate sealing and affecting the consistency of dust prevention and heat dissipation. Summary of the Invention

[0005] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a heat dissipation hole structure for wireless network cards with dustproof mesh. While ensuring efficient heat dissipation, it effectively solves the problem of dust accumulation. The structure is compact and easy to assemble, and it is suitable for the long-term stable operation of high-performance wireless network cards. It has high practicality and market promotion value.

[0006] The technical solution adopted by this utility model to achieve the above-mentioned objective is: a heat dissipation hole structure for a wireless network card with a dustproof mesh, which is integrated into the outer shell structure of the wireless network card, including an air inlet, an air outlet, a mounting base, and a positioning plate.

[0007] The outer shell structure includes a matching upper shell and a lower shell.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 A heat dissipation hole structure for a wireless network card with a dustproof mesh is integrated into the outer shell structure of the wireless network card, including an air inlet 31, an exhaust 32, a mounting base 33, and a positioning plate 34.

[0032] The outer shell structure includes a matching upper shell 1 and a lower shell 2. The mounting base 33 is fixed to the bottom center of the lower shell 2, and a miniature fan 4 is fixedly installed on the mounting base 33. The air inlet 31 is evenly opened in the mounting base 33 and is arranged opposite to the miniature fan 4. A dustproof net A51 is arranged between the miniature fan 4 and the air inlet 31.

[0033] The exhaust is evenly distributed to both sides of the lower housing 2. A dustproof net B52 is arranged on the inner side of the exhaust hole 32. The positioning plate 34 is fixed to the upper housing 1 and keeps in close contact with the inner side of the dustproof net. A ventilation hole 341 is provided on the positioning plate 34, which is arranged opposite to the dustproof net B52.

[0034] The air inlet 31 is designed with a waisted structure that is narrow in the middle and wide at both ends, while the air outlet 32 ​​is designed with an oblique hole structure that is high on the inside and low on the outside.

[0035] Dustproof net A51 can be pressed and positioned by miniature fan 4 and mounting base 33, and dustproof net B52 can be pressed and positioned by positioning plate 34 fixed to the lower housing 2 and the upper housing 1, which has the advantages of convenient installation and replacement.

[0036] The air inlet 31 is designed with a narrow middle and wide ends. Due to the large openings at the top and bottom ends, it can input enough air volume to participate in the cooling of the wireless network card when the micro fan 4 is running. The narrow middle design makes the inner wall of the air inlet 31 form two slopes, thereby preventing dust intercepted by the dust filter A51 from accumulating and clogging in the air inlet 31.

[0037] The exhaust vent 32 is designed with an slanted hole structure that is higher on the inside and lower on the outside, which can prevent dust from adhering to the inner wall of the exhaust vent 32. During the continuous heat dissipation of the wireless network card, the exhaust can further blow out the dust adhering to the inner wall of the exhaust vent 32.

[0038] The structure also has the advantage of easy assembly and disassembly. When the miniature fan 4 is installed on the lower housing 2, the dustproof net A51 can be pressed and positioned. During the assembly and installation of the lower housing 2 onto the upper housing 1, the dustproof net B52 can be pressed and positioned by the positioning plate 34.

[0039] To enable rapid assembly of the upper housing 1 and the lower housing 2, and to facilitate the effective installation of circuit boards and chips within them, the following technical solution is provided.

[0040] The upper shell 1 includes a top plate 11 and a front panel 12 and a rear panel 13 fixed to both sides of the top plate 11 and arranged in parallel. The lower shell 2 includes a bottom plate 21, side plates 22 fixed to both sides of the bottom plate 21 and a wing plate 23 fixed to the top of the side plates 22 and arranged outward. The front panel 12, the rear panel 13 and the side plates 22 are arranged vertically. The wing plate 23 is fixed to the top plate 11 by bolts A61. The mounting base 33 is fixed to the bottom plate 21. The exhaust hole 32 is opened on the side plate 22. The positioning plate 34 is fixed to the top plate 11 and extends vertically downward.

[0041] After the upper housing 1 and the lower housing 2 are nested together, the front panel 12, the rear panel 13 and the side panel 22 can be sealed to form a closed space, so that the circuit board, chip and micro fan 4 can be stably installed and operated in it. When the micro fan 4 is running, it can introduce the bottom air through the air inlet and the dust filter A51, and after dissipating heat from the key chips, it can be discharged outward from the dust filter B52 and the exhaust port.

[0042] To ensure a tight fit between the upper housing 1 and the lower housing 2, the following technical solution is provided.

[0043] The bottom of the upper housing 1 is provided with a positioning groove 14, and the wing plate 23 is nested and fits the positioning groove 14. The inner sidewalls of the front panel 12 and the rear panel 13 are fixed with sealing gaskets 15, and the sealing gaskets 15 are sealed and fitted with the bottom plate 21 and the side plate 22.

[0044] The positioning groove 14 ensures that the wing plate 23 and the upper shell 1 are nested together, while the sealing gasket 15 ensures the sealing effect at the joint between the upper shell 1 and the lower shell 2.

[0045] To ensure effective connection between the wireless network card and network devices, antennas, and other components, an assembly port 16 is provided on the rear panel 13, which facilitates the connection of data cables, antennas, and other components to the corresponding interfaces integrated on the circuit board through the corresponding assembly port 16.

[0046] To ensure that the miniature fan 4 and the dust filter A51 can be stably installed on the mounting base 33, the following technical solution is provided.

[0047] A circular groove 331 is provided on the mounting base 33, and an air inlet 31 is arranged inside the circular groove 331. A dustproof net A51 is nested in the circular groove 331. The miniature fan 4 is fixedly installed above the mounting base 33 by bolts B62, and the air duct of the miniature fan 4 is arranged relative to the circular groove 331.

[0048] The circular recess 331 ensures that the dustproof net A51 is stably installed within it and is arranged between the air inlet 31 and the miniature fan 4. When the miniature fan 4 is running, it allows outside air to enter the air duct of the miniature fan 4 through the air inlet 31 and the dustproof net A51.

[0049] To ensure that the dustproof net B52 can be stably installed inside the side plate 22 and that external air can be effectively delivered to the air inlet 31 located on the bottom plate 21, the following technical solution is provided.

[0050] The inner wall of the side plate 22 is provided with a receiving groove 24, the exhaust hole 32 is arranged inside the receiving groove 24, the dustproof net B52 is nested in the receiving groove 24, and the bottom corner of the bottom plate 21 is fixed with a support leg 25.

[0051] The inclusion slot 24 ensures that the dustproof net B52 is stably arranged therein and fits tightly with the positioning plate 34. The support leg 25 raises the lower housing 2 to ensure that air enters the exhaust hole 32 from the bottom.
