Abstract

This utility model relates to the field of electronic equipment technology, and in particular to a circuit board with rapid heat dissipation. A limiting top frame is provided at the upper end of the bottom frame, and the circuit board body is located between the bottom frame and the limiting top frame. An air inlet duct is sealed and connected at the middle position of the device housing. A small fan is fixedly connected inside the air inlet duct. This utility model allows air to be introduced from the outside through the air inlet duct, and the small fan accelerates air circulation.

Description

Technical Field

[0001] This utility model relates to a circuit board with rapid heat dissipation, belonging to the field of electronic equipment technology. Background Technology

[0002] Circuit boards are the support and electrical connection carriers for electronic components. They are insulating substrates made using printing technology and are used to realize circuit connections between electronic components. They are mainly used to reduce the space occupied by wires and organize the wires in a clear layout. The high reliability and high density of circuit boards enable electronic devices to provide more powerful functions while being miniaturized and lightweight.

[0003] The existing patent number CN219514292U describes a circuit board with rapid heat dissipation. This device, through a limiting frame, a frame, heat dissipation components, and a solder body, facilitates rapid heat dissipation from the device, preventing damage to the circuit board body and extending its service life. The protective components, outer rods, crossbars, and straight rods protect the four corners of the circuit board body, preventing them from being broken by external forces during placement. Meanwhile, the U-shaped clamps, plastic protrusions, and plastic recessed blocks allow operators to stack multiple circuit boards together for secure storage with relatively little effort. However, existing circuit boards are generally installed inside semi-enclosed electrical equipment, and simply absorbing heat is not enough to effectively dissipate it, leading to heat accumulation. Furthermore, while the positioning and storage structure in this device can clamp the circuit boards, they typically do not require multi-layer stacking during installation and are stored individually in packaging. Additionally, existing circuit boards are usually bolted directly to the electrical equipment housing during installation, preventing quick disassembly and assembly. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board with rapid heat dissipation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circuit board with rapid heat dissipation includes a device housing, a bottom frame, and a circuit board body. The bottom frame is located at the upper end of the device housing, and a limiting top frame is located at the upper end of the bottom frame. The circuit board body is located between the bottom frame and the limiting top frame. An air intake duct is sealed and connected at the middle position of the device housing. A small fan is fixedly connected inside the air intake duct. Limiting plates are provided on the upper left and rear sides of the device housing, and the limiting plates are respectively fitted to the bottom frame and the limiting top frame. Limiting plates are provided on the upper front and right sides of the device housing, and the limiting plates are fitted to the bottom frame. An adjusting screw is screwed to the upper side of the limiting plate, and a movable locking plate is rotatably connected to the inner end of the adjusting screw. The movable locking plate is fitted to the limiting top frame.

[0007] Furthermore, a pipe hole is provided at the middle position of the equipment housing, and the position and size of the pipe hole correspond to the position and size of the air intake duct.

[0008] Furthermore, an air intake filter is fixedly connected to the lower inner end of the air intake duct, and a connecting support is spirally connected to the outer side of the air intake duct, with the connecting support fixedly connected to the bottom frame.

[0009] Furthermore, air guide holes and air blowing holes are respectively provided on the inner sides of the bottom frame and the top frame, and the positions of the air guide holes and the air blowing holes are corresponding.

[0010] Furthermore, a torsion block is fixedly connected to the outer end of the adjusting screw.

[0011] Furthermore, the device housing is provided with insertion holes at the front, back, left, and right positions, and the positions of the insertion holes correspond to the positions of the limiting plate and the limiting plate.

[0012] Furthermore, a buckle is slidably connected to the lower inner side of the limiting plate, and a pressing rod is fixedly connected to the outer upper end of the buckle. The pressing rod is slidably connected to the limiting plate, and a spring is covered on the inner surface of the pressing rod.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a perforated duct to allow air to enter from the outside, and a small fan accelerates airflow. An air filter removes dust and impurities from the outside air, allowing clean air to blow heat onto the back of the circuit board. The interconnected air duct and blowing holes direct air towards the upper surface of the circuit board, rapidly dissipating heat from the upper surface and electronic components. The incoming air is then expelled through the heat dissipation vents of the electrical equipment, further enhancing the circuit board's heat dissipation. Simultaneously, it also dissipates heat from other components inside the electrical equipment. A limiting plate allows for pre-installation of the circuit board, and the rotation of a toggle block... The adjusting screw can move the movable clamping plate, allowing the limiting clamping plate and the movable clamping plate to cooperate in fixing the bottom frame and the limiting top frame. The circuit board can be fixed between the bottom frame and the limiting top frame simultaneously, enabling quick installation of the circuit board. When disassembly is required, the movable clamping plate can be moved outward by rotating the torsion block in the opposite direction, allowing the limiting top frame to be disassembled, thus enabling quick removal of the circuit board. Pressing the pressing rod compresses the spring, causing the buckle to move inward, allowing the limiting clamping plate and the limiting plate to be disassembled quickly, and the bottom frame to be removed. The spiral connection between the connecting support and the air intake duct allows the air intake duct to be disassembled separately, facilitating the quick disassembly of various components and reducing the replacement cost of damaged individual parts.

A small fan 6 is fixedly connected inside the air inlet duct 5. A pipe hole 11 is opened at the middle position of the housing 1, and the position and size of the pipe hole 11 correspond to the position and size of the air inlet duct 5. An air inlet filter 12 is fixedly connected to the lower inner side of the air inlet duct 5. A connecting support 13 is spirally connected to the outer side of the air inlet duct 5. The connecting support 13 is fixedly connected to the base frame 2. Air guide holes 14 and air blowing holes are respectively opened on the inner sides of the base frame 2 and the top frame. The positions of the air inlet 15, air guide hole 14, and air blowing hole 15 are corresponding. The air inlet duct 5 can introduce air from the outside through the function of the pipe hole 11. The small fan 6 can accelerate the air circulation. The air inlet filter 12 filters dust and impurities from the outside air, so that the clean air can blow air to the back of the circuit board for heat dissipation. The through arrangement of the air guide hole 14 and air blowing hole 15 allows the air to be blown to the upper surface of the circuit board, thereby quickly dissipating heat from the upper surface of the circuit board and various electronic components. The air is then discharged through the heat dissipation vent of the electrical equipment, improving the heat dissipation effect of the circuit board and also dissipating heat from other components inside the electrical equipment.

[0025] Please refer to Example 2 Figures 1-5The difference between this embodiment and Embodiment 1 is that: Limiting plates 7 are provided on the upper left and rear sides of the equipment housing 1, respectively, and these plates are in contact with the bottom frame 2 and the top limiting frame 3.

Pressing the pressing rod 19 compresses the spring 20 and moves the buckle 18 inward, so that the limiting clamping plate 7 and the limiting plate 8 can be quickly disassembled, and the bottom frame 2 can be removed. The spiral connection between the connecting support 13 and the air intake duct 5 allows the air intake duct 5 to be disassembled separately, so as to facilitate the quick disassembly of each component and reduce the replacement cost after the damage of a single part.

[0026] The working principle of this utility model is as follows: During use, the air intake duct 5, with its perforation 11, allows air to be introduced from the outside. A small fan 6 accelerates airflow, and the air intake filter 12 filters out dust and impurities from the outside air. This clean air then blows heat onto the back of the circuit board. The through-holes 14 and 15 allow air to be blown onto the upper surface of the circuit board, rapidly dissipating heat from the upper surface and various electronic components. The incoming air is then expelled through the heat dissipation vents of the electrical equipment, further enhancing the heat dissipation of the circuit board. Simultaneously, it also dissipates heat from other components inside the electrical equipment. The limiting plate 7 allows for pre-installation of the circuit board, and the rotation of the torsion block 16 adjusts the screw... The lever 9 can move the movable plate 10 so that the limiting plate 7 and the movable plate 10 can cooperate to fix the bottom frame 2 and the limiting top frame 3. The circuit board can be fixed between the bottom frame 2 and the limiting top frame 3 at the same time, realizing the quick installation of the circuit board. When disassembly is required, the movable plate 10 can be moved outward by rotating the torsion block 16 in the opposite direction, and the limiting top frame 3 can be disassembled, so that the circuit board can be quickly removed. Pressing the pressing rod 19 compresses the spring 20 and moves the buckle 18 inward, so that the limiting plate 7 and the limiting plate 8 can be quickly disassembled, and the bottom frame 2 can be removed.
