Description

Technical Field

[0001] The utility model relates to the technical field of circuit board heat dissipation, in particular to a high-stability computer circuit board that is convenient for heat dissipation. Background Art

[0002] Computer circuit boards are mainly composed of substrates and wires. The substrate is the support of electronic components and is usually made of paper, glass fiber, epoxy resin and other materials. The wires are obtained by copper plating and chemical etching on the surface of the substrate. In addition, various electronic components such as resistors, capacitors, transistors, etc. need to be installed on the circuit board.

[0003] The electronic components on the circuit board will generate heat due to power consumption during operation. If the heat on the circuit board cannot be effectively dissipated, the temperature will rise, which will not only reduce the performance of the circuit board, but also shorten the life of the electronic components. Therefore, when the circuit board is working, it needs to be cooled.

[0004] At present, a main heat dissipation method for computer circuit boards is to install a cooling fan next to the circuit board to remove the heat through air flow. However, the installation position of the cooling fan is usually fixed, so the flowing air can only cover a local area of ​​the circuit board, making it difficult to effectively dissipate the heat of the entire circuit board, resulting in poor heat dissipation effect.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0008] It can be seen that a tubular cylinder and a cooling fan are arranged in the middle of the computer circuit board body, a guide plate is arranged around the tubular cylinder on the computer circuit board body, and the airflow formed by the cooling fan is blocked and diverted by the sealing plate to flow from the guide groove to the cooling cavity formed between the two adjacent guide plates and the surface of the computer circuit board body, thereby forming an airflow that flows radially toward the periphery on the side of the computer circuit board body away from the electronic components, so that the air blowing and cooling range is sufficient to cover most areas of the entire computer circuit board body, thereby improving the heat dissipation effect of the computer circuit board body and ensuring higher stability during operation.

[0009] Furthermore, a surface of the computer circuit board body on one side facing away from the electronic components is provided with a plurality of mounting grooves arranged around the tubular cylinder array; a fixing plate is fixed on each guide plate, the overall cross-section of the guide plate and the fixing plate is T-shaped, and the fixing plates are correspondingly embedded and fixed in the mounting grooves; both the guide plate and the fixing plate are made of aluminum.

[0010] By fixing the fixing plate on the guide plate and embedding the fixing plate into the mounting groove on the surface of the computer circuit board body, the firmness of the guide plate during installation is ensured, and at the same time, the contact area with the computer circuit board body is increased, and the range of heat transfer is increased. The guide plate and the fixing plate are made of aluminum, thereby further improving the heat dissipation effect on the computer circuit board body.

[0011] Furthermore, the blocking plate is installed in the annular sleeve, and the annular sleeve is detachably installed on the end of the tubular cylinder through threads.

[0012] The blocking plate is installed in the annular sleeve and the annular sleeve is screwed onto the end of the tubular cylinder by means of a thread, so that the blocking plate is easy to disassemble and assemble, thereby facilitating the inspection and maintenance of the heat dissipation fan in the tubular cylinder.

[0013] Furthermore, heat dissipation holes are distributed on the surface of the computer circuit board body facing away from the electronic components; the heat dissipation holes extend along the thickness direction of the computer circuit board body and penetrate to the other side of the computer circuit board body.

[0014] By evenly distributing heat dissipation holes on both sides of the computer circuit board body, it is ensured that heat is transferred from one side of the computer circuit board body through the heat dissipation holes to the side away from the electronic components, further accelerating the heat transfer.

[0015] Furthermore, a dust filter is installed at one end of the tubular body away from the sealing plate.

[0016] By arranging a dust filter at the air inlet end of the tubular cylinder, dust impurities in the air can be filtered to prevent them from entering the tubular cylinder and causing pollution.

[0017] Furthermore, mounting legs extending along the thickness direction of the computer circuit board body are fixed at the four top corners of the surface of the side of the computer circuit board body facing away from the electronic components, and mounting feet are provided on the ends of the mounting legs; the distance between the end of the tubular cylinder away from the dust filter and the surface of the computer circuit board body facing away from the electronic components is less than the length of the mounting legs.

[0029] During the operation of the computer circuit board, the heat generated by the electronic components is transferred to the computer circuit board body 1, and the computer circuit board body 1 transfers the heat to the guide plate 4.
