Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board with rapid heat dissipation. Background Technology

[0002] In modern electronic devices, circuit boards, as the support structure for electronic components and the key carrier for electrical connections, are of paramount importance. With the rapid development of electronic technology, electronic devices are making great strides towards miniaturization, high performance, and high integration; chip performance is constantly improving, and a large number of electronic components are densely integrated on circuit boards, which leads to a sharp increase in the heat generated during device operation.

[0003] For circuit boards, efficient heat dissipation has become a core element in ensuring stable operation, extending service life, and guaranteeing the overall performance of electronic devices. In the past, traditional circuit boards relied heavily on natural heat dissipation to address heat issues. This method mainly relied on natural air convection to slowly remove the heat generated by electronic components on the circuit board. However, natural heat dissipation is weak and heat transfer efficiency is low, causing heat to easily accumulate on the circuit board. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circuit board with rapid heat dissipation, thus avoiding the problem of inefficient traditional natural heat dissipation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A circuit board with rapid heat dissipation includes a circuit board body, a hook fixedly connected to the outer side of the circuit board body, a first protective cover provided on the upper side of the circuit board body, an opening for cooperating with the hook in the middle of the outer side of the first protective cover, a window on the upper side of the opening, a pull plate provided on the inner side of the window, a through hole in the middle of the pull plate, a ring fixedly connected to the upper side of the pull plate outside the through hole, a fixing frame fixedly connected to the inner side of the ring, a servo motor fixedly connected to the lower side of the fixing frame, a fan blade provided on the upper side of the fixing frame, the drive end of the servo motor fixedly connected to the middle of the fan blade, and a dustproof component provided on the upper side of the fan blade.

[0007] Furthermore, the dustproof assembly includes a filter plate fixedly connected to the top of the inner wall of the ring, a rotating shaft rotatably connected to the middle of the filter plate, the lower end of the rotating shaft fixedly connected to the upper middle of the fan blade, and an arc-shaped scraper fixedly connected to the outer side of the upper end of the rotating shaft, with the lower side of the arc-shaped scraper in close contact with the upper side of the filter plate.

[0008] Furthermore, a second protective cover is fixedly connected to the upper outer side of the ring body, and a side hole is opened on the outer side of the second protective cover, and an air inlet is opened on the upper side of the second protective cover.

[0009] Furthermore, the end of the arc-shaped scraper is tightly fitted against the inner wall of the second protective cover.

[0010] Furthermore, a collection trough plate is fixedly connected to the outer wall of the ring body on the lower side of the second protective cover.

[0011] Furthermore, air vents are provided at both the front and rear ends of the left and right sides of the first protective cover.

[0012] Furthermore, the left and right ends of the circuit board body are fixedly connected with fixing ears for fixation.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the hook on the outside of the circuit board body and the opening of the first protective cover are designed to cooperate, so that the first protective cover can be quickly installed and disassembled without the need for additional tools such as screwdrivers and wrenches, which greatly reduces the installation difficulty and time cost. At the same time, the pull-out plate allows the core heat dissipation components such as the ring body, servo motor, and fan blades to be easily disassembled. When a fault occurs or cleaning is required, technicians can quickly separate the components for inspection and maintenance, which effectively improves the equipment maintenance efficiency and reduces maintenance costs.

[0015] 2. In this utility model, the fan blades are driven to rotate at high speed by a servo motor, which can form a strong and stable airflow. External air enters through the air inlet, is filtered, and is precisely directed towards the circuit board body. Compared with traditional heat dissipation methods, the heat dissipation efficiency is greatly improved. The filter plate can effectively intercept dust and other impurities in the air, preventing them from entering the circuit board and damaging the components. At the same time, when the fan blades rotate, they drive the arc-shaped scraper to rotate synchronously, continuously cleaning the surface of the filter plate, so that dust cannot accumulate on the filter plate, ensuring that the filtration effect is always maintained in a good state.

[0023] 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.

[0024] Reference Figures 2-4 This utility model provides an embodiment of a circuit board with rapid heat dissipation, including a circuit board body 1, a hook 2 fixedly connected to the outer side of the circuit board body 1, a first protective cover 3 provided on the upper side of the circuit board body 1, an opening 4 for cooperating with the hook 2 in the middle of the outer side of the first protective cover 3, a window 5 provided on the upper side of the opening 4, a pull plate 6 provided on the inner side of the window 5, a through hole 7 provided in the middle of the pull plate 6, a ring 8 fixedly connected to the upper side of the pull plate 6 outside the through hole 7, a fixing frame 9 fixedly connected to the inside of the ring 8, a servo motor 10 fixedly connected to the lower side of the fixing frame 9, a fan blade 11 provided on the upper side of the fixing frame 9, the drive end of the servo motor 10 fixedly connected to the middle of the fan blade 11, air vents 20 provided at the front and rear ends of both sides of the first protective cover 3, and fixing ears 19 fixedly connected to both ends of the circuit board body 1 for fixing.

[0025] The opening 4 on the first protective cover 3 is precisely aligned with the hook 2 on the outside of the circuit board body 1, so that the two fit together tightly, thereby firmly installing the first protective cover 3 on the upper side of the circuit board body 1. The installation is convenient and the disassembly is simple, without the need for additional tools. After the servo motor 10 is started, its drive end drives the fan blade 11 to rotate at high speed, which causes the gas to flow rapidly and form a strong airflow. The external air is blown in a direction towards the circuit board body 1, and the airflow efficiently removes the large amount of heat generated by the circuit board body 1 during operation. Then the airflow carrying the heat is discharged from the air outlet 20 on the left and right sides and the front and rear ends of the first protective cover 3, realizing rapid heat dissipation and ensuring that the circuit board operates stably at a suitable temperature.

[0026] Reference Figure 1 , Figure 3 and Figure 5 A filter plate 12 is fixedly connected to the top of the inner wall of the ring body 8. A rotating shaft 13 is rotatably connected to the middle of the filter plate 12. The lower end of the rotating shaft 13 is fixedly connected to the upper middle of the fan blade 11. An arc-shaped scraper 14 is fixedly connected to the outer side of the upper end of the rotating shaft 13. The lower side of the arc-shaped scraper 14 is in close contact with the upper side of the filter plate 12. A second protective cover 15 is fixedly connected to the outer side of the upper end of the ring body 8. A side hole 16 is opened on the outer side of the second protective cover 15. An air inlet 17 is opened on the upper side of the second protective cover 15. The end of the arc-shaped scraper 14 is in close contact with the inner wall of the second protective cover 15. A collection trough plate 18 is fixedly connected to the outer wall of the ring body 8 below the second protective cover 15.

[0027] External air enters through the air inlet 17 on the upper side of the second protective cover 15, passes through the filter plate 12 inside the ring body 8 to filter impurities, and is then blown directionally towards the circuit board body 1 for continuous heat dissipation. During continuous heat dissipation, when the fan blade 11 rotates, it drives the arc-shaped scraper 14 to rotate synchronously through the rotating shaft 13. Since the lower side of the arc-shaped scraper 14 is in close contact with the filter plate 12, as it rotates, the arc-shaped scraper 14 can promptly remove dust and other impurities intercepted on the filter plate 12. The cleaned dust falls into the collection trough plate 18 through the side hole 16 on the outer side of the second protective cover 15, effectively preventing dust accumulation from affecting the filtration effect and airflow, and ensuring the long-term efficient operation of the heat dissipation system. In terms of equipment maintenance, when it is necessary to inspect or clean the heat dissipation components, the pull plate 6 can be pulled forward along the opening 5. At this time, the ring body 8, servo motor 10, fan blade 11 and other components can be removed from the first protective cover 3 together. The operation is simple and convenient for technicians to inspect, repair and clean each component.

[0028] Working principle: Align the opening 4 on the first protective cover 3 with the hook 2, so that the hook 2 and the opening 4 cooperate, and install the first protective cover 3 on the upper side of the circuit board body 1. Start the servo motor 10 to drive the fan blade 11 to rotate. The rotating fan blade 11 promotes gas flow and forms an airflow. The airflow enters through the air inlet 17, passes through the ring body 8 and blows towards the circuit board body 1. The heat generated by the airflow is discharged from the air outlet 20 on the left and right sides of the first protective cover 3. The pull plate 6 can be pulled forward from the opening 5, so that the ring body 8, servo motor 10 and fan blade 11 can be removed from the first protective cover 3 for easy maintenance. During the rotation of the fan blade 11, the arc scraper 14 is driven to rotate through the rotating shaft 13. The rotating arc scraper 14 is in close contact with the filter plate 12. The filter plate 12 is used for filtration. During the rotation of the arc scraper 14, the dust generated by filtration is cleaned. The cleaned dust is collected in the collection trough plate 18 through the side hole 16.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
