Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a high-efficiency heat-conducting video circuit board. Background Technology

[0002] Circuit boards are one of the most commonly used components in electrical equipment, and also one of the most important components for controlling electrical equipment. Circuit boards are often used in video playback devices. However, after prolonged use, the circuit boards of video playback devices will generate a lot of heat due to excessive operating time. If the heat is not dissipated in time, it is very easy to cause the circuit board to overheat. This can result in video device lag or even shorten the lifespan of the circuit board or burn it out. Therefore, heat dissipation of video circuit boards is particularly important.

[0003] Patent CN221058498U discloses a high-efficiency thermally conductive LED display circuit board, including a circuit board body and a heat-conducting box disposed on its upper side. Heat exchange posts and heat exchange holes are plugged into each other. The heat dissipation medium within the heat-conducting cavity circulates between evaporation and condensation channels, achieving a heat absorption effect on the circuit board body. This reduces the operating temperature of the circuit board body, extends its service life, and improves its performance. While this patent achieves heat dissipation, after prolonged operation, a large amount of heat accumulates within the heat dissipation medium, making it difficult to dissipate. This affects its heat absorption effect on the circuit board, thus impacting the overall thermal conductivity and heat dissipation performance. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat-conducting video circuit board, including a mounting plate, a mounting groove on the top of the mounting plate, a heat-conducting plate snapped onto the inner side of the mounting groove, a circuit board body snapped onto the inner side of the mounting groove and on top of the heat-conducting plate, a heat-conducting pipe embedded and fixedly mounted on the top of the heat-conducting plate, the interior of the heat-conducting pipe being filled with condensate, the top of the circuit board body being in contact with the top of the heat-conducting pipe, a fan embedded in the bottom of the side of the mounting plate, the bottom of the heat-conducting plate not contacting the bottom of the inner side of the mounting groove, a ventilation cavity being formed between the bottom of the heat-conducting plate and the inner side of the mounting groove, and the fan being located on both sides of the ventilation cavity.

[0011] Compared with the prior art, this utility model provides a video circuit board with high thermal conductivity, which has the following beneficial effects:

[0012] 1. This high-efficiency heat-conducting video circuit board contacts the circuit board body through a heat pipe. When the circuit board body generates heat due to operation, the heat is absorbed by the condensate in the heat pipe. Then, the fan is activated. The fan located on the left side of the mounting plate blows cool air from the outside into the mounting groove. After entering the ventilation cavity, the air blows onto the bottom of the heat pipe, absorbing the heat in the condensate. Then, the fan located on the right side of the mounting plate draws away the hot air in the ventilation cavity. In this way, heat dissipation of the circuit board body is achieved, and the continuous cooling of the condensate is ensured. This avoids the problem of the condensate overheating and reducing the heat absorption effect, thus improving the effectiveness and sustainability of heat dissipation of the circuit board body.

[0019] 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.

[0020] Example 1

[0021] Please see Figure 1-4 In this embodiment: a high-efficiency heat-conducting video circuit board includes a mounting plate 1. A mounting groove 11 is formed on the top of the mounting plate 1. A heat-conducting plate 4 is snapped onto the inner side of the mounting groove 11. A circuit board body 2 is snapped onto the inner side of the mounting groove 11 and located on top of the heat-conducting plate 4. A heat-conducting pipe 41 is embedded and fixedly mounted on the top of the heat-conducting plate 4. The interior of the heat-conducting pipe 41 is filled with condensate. The top of the circuit board body 2 is in contact with the top of the heat-conducting pipe 41. A fan 3 is embedded in the bottom side of the mounting plate 1. The bottom of the heat-conducting plate 4 does not contact the bottom inner side of the mounting groove 11. A ventilation cavity is formed between the bottom of the heat-conducting plate 4 and the inner side of the mounting groove 11. The fan 3 is located on both sides of the ventilation cavity. With this design, the heat pipe 41 contacts the circuit board body 2. When the circuit board body 2 generates heat due to operation, the heat is absorbed by the condensate in the heat pipe 41. Then, the fan 3 is activated. The fan 3 located on the left side of the mounting plate 1 blows cool air from the outside into the mounting groove 11. After entering the ventilation cavity, the air blows onto the bottom of the heat pipe 41, absorbing the heat in the condensate. Then, the fan 3 located on the right side of the mounting plate 1 draws away the hot air in the ventilation cavity. In this way, heat dissipation of the circuit board body 2 is achieved, and the continuous cooling of the condensate is ensured. This avoids the problem of the condensate overheating and reducing the heat absorption effect, thus improving the effectiveness and sustainability of heat dissipation of the circuit board body 2.

[0022] As a preferred embodiment, there are multiple fans 3 symmetrically distributed on both sides of the ventilation cavity, and each fan 3 blows air in the same direction, which ensures that the air in the ventilation cavity is always in a circulating state and quickly removes heat.

[0023] In a preferred embodiment, the surface of the heat-conducting plate 4 is provided with a through groove 45 that runs vertically through the plate. The heat-conducting pipe 41 is fixedly installed inside the through groove 45. There are multiple heat-conducting pipes 41 and they are evenly distributed on the surface of the heat-conducting plate 4. This ensures the installation stability of the heat-conducting pipes 41. At the same time, the condensate in the upper part of the heat-conducting pipe 41 absorbs heat from the circuit board body 2, causing the condensate to heat up. The condensate in the lower part of the heat-conducting pipe 41 is cooled down by the fan 3, which carries away the heat and ensures the efficiency and continuity of heat dissipation.

[0024] Example 2

[0025] Please see Figure 1-4 In this embodiment, adjacent heat-conducting plates 4 are interconnected by a connecting pipe 42 embedded in the surface of the heat-conducting plate 4. A micro liquid pump 44 is installed in the middle of one of the heat-conducting pipes 41. The micro liquid pump 44 is embedded in the surface of the heat-conducting plate 4. When the micro liquid pump 44 is connected to an external power source, the condensate in the heat-conducting pipe 41 flows through the connecting pipe 42. This can accelerate the heat absorption of the circuit board body 2 and make the condensate mix evenly, thus accelerating heat conduction and improving the heat dissipation efficiency of the fan 3.

[0026] In a preferred embodiment, the top of the mounting plate 1 and the edge of the mounting groove 11 are provided with symmetrically distributed limiting grooves 12. The side of the heat-conducting plate 4 is fixedly installed with a limiting block 43 that is engaged with the limiting groove 12. The bottom of the limiting block 43 is in contact with the bottom of the limiting groove 12. This can ensure the stability of the installation of the heat-conducting plate 4 and at the same time ensure the stability of the air flow in the ventilation cavity.

[0027] In a preferred embodiment, symmetrically distributed plug-in blocks 21 are fixedly installed on the side of the circuit board body 2. The plug-in blocks 21 are snapped into the inner side of the limiting groove 12, and the top of the plug-in blocks 21 extends to the top of the limiting groove 12. This can improve the installation stability of the circuit board body 2 and further limit the heat conduction plate 4.

[0028] The working principle and usage process of this utility model are as follows: The operator contacts the circuit board body 2 through the heat pipe 41. When the circuit board body 2 generates heat due to operation, the heat is absorbed by the condensate in the heat pipe 41. Then, the fan 3 is turned on. The fan 3 located on the left side of the mounting plate 1 blows cool air from the outside into the mounting groove 11. After entering the ventilation cavity, the air blows onto the bottom of the heat pipe 41, absorbing the heat in the condensate. Then, the fan 3 located on the right side of the mounting plate 1 draws away the hot air in the ventilation cavity. In this way, heat dissipation of the circuit board body 2 is achieved, and the continuous cooling of the condensate is ensured. This avoids the problem of the condensate overheating and the resulting reduction in heat absorption effect, thus improving the effectiveness and continuity of heat dissipation of the circuit board body 2. After the micro liquid pump 44 is turned on, the condensate in the heat pipe 41 is made to flow through the connecting pipe 42. On the one hand, this accelerates the heat absorption of the circuit board body 2, and on the other hand, it makes the condensate mix evenly from top to bottom, accelerating heat conduction. This increases the heat dissipation efficiency of the fan 3 on the condensate.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
