Description

Technical Field

[0001] This utility model relates to the field of notebook computers, and in particular to a dustproof structure for notebook computer air ducts. Background Technology

[0002] A laptop's airflow system is an internal airflow channel system designed to optimize heat dissipation efficiency. By rationally planning the location of air inlets and outlets and the airflow path, it guides cool air to flow over heat-generating components (such as the CPU, GPU, and memory), absorbs heat, and then expels the hot air outside the laptop, thereby maintaining the hardware operating within a safe temperature range.

[0003] However, in the existing dustproof structure of laptop air ducts, dust and lint can easily enter the air duct from the air inlet during use and remain on the fan blades and air outlet, thus affecting the heat dissipation effect of the fan.

[0004] Therefore, it is essential to invent a dustproof airflow structure for laptops. Utility Model Content

[0031] Example

[0032] Reference Figure 1-7A dustproof structure for a laptop air duct includes a fan base 1, a fan cover 2, a motor 3, an impeller 4, and a laptop back cover 20. The motor 3 is fixedly installed in the fan base 1. The impeller 4 is rotatably mounted on the output end of the motor 3 via a plug-in connection. The fan cover 2 is detachably installed on the fan base 1 so that the impeller 4 can be removed for cleaning after the fan cover 2 is removed. An air outlet 6 is provided between the fan cover 2 and the fan base 1 so that the heat-exchanged gas can be discharged from the air outlet 6. The fan cover 2 has an air inlet 8, which is connected to the air outlet 6. The impeller 4 rotates between the air outlet 6 and the air inlet 8 so that when the impeller 4 rotates, it draws in cold air from the air inlet 8 and then discharges it from the air outlet 6. A dustproof structure is fixedly installed on the outside of the air inlet 8 of the fan cover 2 so that the air drawn in from the air inlet 8 can be filtered through the dustproof structure. A support structure is fixedly installed on the outside of the dustproof structure so that it can be fixedly connected to the back cover 20 of the laptop.

[0033] It should be noted that the motor 3 and impeller 4 adopt existing technologies, such as the SEPA HY60Q-05A cooling fan in existing technologies, so they will not be described in detail here.

[0034] Specifically, the dustproof structure includes an outer filter cartridge 9, an intermediate filter cartridge 10, and an inner filter cartridge 11. The outer filter cartridge 9, the intermediate filter cartridge 10, and the inner filter cartridge 11 are coaxially fixed on the outside of the air inlet 8 of the fan cover plate 2 from the outside to the inside, so as to have a larger filtration area in a specific space, thereby improving the filtration time.

[0035] Specifically, a filter element 12 is fixedly installed at the top of the outer filter cartridge 9 and the intermediate filter cartridge 10 so as to filter the gas passing between the outer filter cartridge 9 and the intermediate filter cartridge 10 through the filter element 12;

[0036] Specifically, a filter element 2 13 is fixedly installed at the bottom between the intermediate filter cartridge 10 and the inner filter cartridge 11 so that the gas passing between the intermediate filter cartridge 10 and the inner filter cartridge 11 can be filtered through the filter element 2 13.

[0037] Specifically, a filter element 3 14 is fixedly installed at the top of the inner filter cartridge 11 so that the gas can be filtered through the filter element 3 14 from the top of the inner filter cartridge 11.

[0038] Specifically, the outer filter cartridge 9, the middle filter cartridge 10, the inner filter cartridge 11, and the filter plate 7 adopt existing technologies, such as metal dustproof mesh (stainless steel / aluminum alloy, particle size >50μm interception) and PVC encrypted dustproof mesh (0.5mm mesh size) in existing technologies;

[0039] Specifically, filter element 12, filter element 23, and filter element 34 adopt existing technologies, such as nylon 66 filter cloth (15-micron filter pores), metal dustproof mesh (stainless steel / aluminum alloy), PVC encrypted dustproof mesh (0.5mm mesh), and pre-filter (white non-woven fabric).

[0040] Specifically, the support structure is detachably connected to the laptop back cover 20, so that the fan cover 2 and the dustproof structure can be removed together when the support structure is disassembled.

[0041] Specifically, the impeller 4 is coaxial with the air inlet 8 and is located between the fan cover 2 and the motor 3. The diameter of the air inlet 8 is smaller than the diameter of the impeller 4. With this structure, the impeller 4 can be limited and prevented from falling off when it is rotating normally.

[0042] Specifically, the fan base 1 has at least one fixing ear 19 on its outer side. The fan base 1 is detachably connected to the laptop motherboard through the fixing ear 19 and fasteners (such as bolts) so that the fan base 1 can be disassembled later.

[0043] Specifically, the fan base 1 has a heat dissipation hole 5 on the side where the motor 3 is installed, so that the motor 3 can be better dissipated through the heat dissipation hole 5.

[0044] Specifically, several filter plates 7 are evenly and obliquely fixed on the fan cover plate 2. All filter plates 7 are located in the air outlet 6 and do not contact each other, so that dust and lint in the air can be filtered again during exhaust, preventing a large amount of dust and lint from entering the condenser.

[0045] Specifically, the support structure includes a support block 15, a fixing plate 16, filter holes 17, and fixing holes 18. The fixing plate 16 is fixedly connected to the fan cover 2 through at least one support block 15 to ensure the stability between the fixing plate 16 and the fan cover 2, while avoiding large-area obstruction of the external filter cartridge 9 by the support block 15. The dustproof structure is located between the fixing plate 16 and the fan cover 2. Several filter holes 17 are provided through the fixing plate 16 to intercept larger objects and prevent foreign objects from entering the laptop. The filter holes 17 are connected to the dustproof structure so that air can enter the dustproof structure through the filter holes 17. The fixing plate 16 has at least one fixing hole 18, which is detachably connected to the laptop back cover 20 with fasteners (such as bolts) so that the fixing plate 16 and the laptop back cover 20 can be disassembled and assembled.

[0046] Specifically, the laptop back cover 20 has mounting holes 21 corresponding to the fixing plate 16, so that the support structure, fan cover 2 and dustproof structure can be disassembled at the same time through the mounting holes 21. After the support structure, fan cover 2 and dustproof structure are disassembled, the impeller 4 can be disassembled through the mounting holes 21. The fixing plate 16 is installed in the mounting holes 21 of the laptop back cover 20 through the fixing holes 18 and fasteners 2. After the fixing plate 16 is installed in place, the outer surface of the fixing plate 16 is flush with the outer surface of the laptop back cover 20.

[0047] In this embodiment, when in use, the motor 3 drives the impeller 4 to draw air into the dustproof structure through the filter hole 17, and the air is filtered for dust and impurities through the filter hole 17 and the dustproof structure, and then discharged through the air outlet 6. When the air is discharged through the air outlet 6, the filter plate 7 filters the dust and lint in the air again to prevent a large amount of dust and lint from entering the condenser.

[0048] When cleaning is required later, simply remove fastener 2 to simultaneously disassemble the support structure, fan cover 2, and dustproof structure. After the support structure, fan cover 2, and dustproof structure are disassembled, the impeller 4 can be removed through the mounting hole 21 for cleaning.

[0049] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
