Description

Technical Field

[0001] This utility model belongs to the field of electronic communication technology, and specifically relates to a three-dimensional heat dissipation structure for a power amplifier. Background Technology

[0002] With the rapid development of electronic technology, power amplifiers are widely used in audio equipment, communication equipment, broadcasting and television and other electronic systems. As an electrical device that can amplify input signals, power amplifiers usually require high power drive and high energy conversion. Therefore, they generate a lot of heat during operation. If heat dissipation is not effective, the performance of the power amplifier will be affected, and it may even be damaged due to overheating. In order to improve the performance and reliability of power amplifiers, heat dissipation has always been a key challenge in design and application.

[0003] The prior art patent publication number CN210298353U describes a three-dimensional heat dissipation structure for a power amplifier. This patent includes a heat sink comprising a square heat sink body and heat sink fins disposed within the heat sink body. The heat sink body is surrounded by a top panel, a bottom panel, a left side panel, and a right side panel. The top and bottom panels are made of materials with good thermal conductivity. A fixing frame is fixed to one end of the heat sink body, and several fans are evenly arranged on the fixing frame. Several power amplifier modules are provided, respectively fixed to the top and bottom panels, and connected to each other via radio frequency cables… This device achieves directional airflow through the fans, efficiently dissipating heat. However, in practical use, it still has the following shortcomings: In practice, this device uses fans to accelerate airflow for heat dissipation, but when the ambient temperature around the power amplifier is high, accelerating airflow alone is ineffective. Furthermore, the fans consistently provide the same airflow force, which can negatively impact the operation of the power amplifier when the ambient temperature is low.

[0004] Therefore, a three-dimensional heat dissipation structure for power amplifiers is needed to solve the problems of poor cooling effect caused by simply accelerating airflow and the inability to adjust the fan intake size, which can easily affect the operation of the power amplifier. Utility Model Content

[0005] The purpose of this invention is to provide a three-dimensional heat dissipation structure for a power amplifier to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional heat dissipation structure for a power amplifier, comprising a power amplifier body, an air regulating mechanism on the top of the power amplifier body, a top cover fixedly connected to the top of the air regulating mechanism, a liquid inlet fixedly connected to one side of the top cover, a liquid outlet fixedly connected to the other side of the top cover, a flow slowing mechanism between the liquid inlet and the liquid outlet, and two cooling fans fixedly connected to the top of the top cover.

[0007] It should be noted in the solution that the air adjustment mechanism includes a frame fixedly connected to the top of the power amplifier body. Multiple first rotating shafts are rotatably connected between the inner walls of the two sides of the frame. Each of the multiple first rotating shafts has a baffle plate fixedly connected to its outer wall. Each of the multiple first rotating shafts has a synchronous pulley fixedly connected through the frame on one side. A synchronous belt is installed on the outer wall of the multiple synchronous pulleys. A concave frame is fixedly connected to one side of the frame. A servo motor is fixedly connected to the outer side of the concave frame.

[0008] It is worth noting that multiple of the aforementioned synchronizing pulleys are on the same horizontal plane.

[0009] Furthermore, it should be noted that the output end of the servo motor is fixedly connected to one of the synchronous pulleys through the concave frame.

[0010] In a preferred embodiment, the flow control mechanism includes a flow control tube fixedly connected between the inlet and the outlet. Multiple upper baffles are fixedly connected to the top of the inner wall of the flow control tube, and multiple lower baffles are fixedly connected to the bottom of the inner wall of the flow control tube. Multiple second rotating shafts are fixedly connected between the front and rear ends of the inner wall of the flow control tube. Multiple fan blades are rotatably connected to the outer walls of the multiple second rotating shafts, and scrapers are fixedly connected to the outer sides of the multiple fan blades.

[0011] In a preferred embodiment, the slow-flow tube is designed in a serpentine bend.

[0012] In a preferred embodiment, the plurality of upper baffles and lower baffles are staggered, and the scraper is in contact with the surfaces of the upper baffles and the lower baffles.

[0013] Compared with the prior art, the three-dimensional heat dissipation structure for power amplifiers provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting up a flow-slowing mechanism and a cooling fan, while the cooling fan accelerates the airflow, the inlet and outlet are connected to external refrigeration equipment. The coolant enters the flow-slowing pipe from the inlet. The air blown out by the cooling fan becomes cold air under the action of the coolant and acts on the power amplifier body, which can significantly improve the overall heat dissipation efficiency and effectively reduce the operating temperature of the power amplifier. At the same time, the multiple upper and lower baffles in the flow-slowing pipe can slow down the flow rate of the coolant, making its flow more stable, increasing the residence time of the coolant in the flow-slowing pipe, improving the heat exchange efficiency, and making the heat dissipation effect more efficient.

[0015] (2) By setting up an air conditioning mechanism, the air force can be adjusted by opening and closing multiple baffles. The air force can be dynamically adjusted according to the changes in the operating temperature of the power amplifier. In this way, the cooling fan will not always provide the same air force, but can be adjusted according to the actual needs of the ambient temperature. By effectively adjusting the airflow, the heat dissipation effect is optimized. When the temperature is high, the air force increases, which helps to quickly reduce the temperature of the power amplifier. When the temperature is low, the air force decreases, so as to avoid excessive air force affecting the stability of the power amplifier. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a three-dimensional heat dissipation structure for a power amplifier, including a power amplifier body 1, a wind regulating mechanism 2 on the top of the power amplifier body 1, a top cover 3 fixedly connected to the top of the wind regulating mechanism 2, a liquid inlet 4 fixedly connected to one side of the top cover 3, a liquid outlet 5 fixedly connected to the other side of the top cover 3, a flow slowing mechanism 6 between the liquid inlet 4 and the liquid outlet 5, and two cooling fans 7 fixedly connected to the top of the top cover 3.

[0023] Further as Figure 3As shown, it is worth noting that the air conditioning mechanism 2 includes a frame 201 fixedly connected to the top of the power amplifier body 1. Multiple first rotating shafts 202 are rotatably connected between the inner walls of both sides of the frame 201. Each of the multiple first rotating shafts 202 has a baffle plate 203 fixedly connected to its outer wall. A synchronous pulley 204 is fixedly connected to one side of each of the multiple first rotating shafts 202, penetrating the frame 201. A synchronous belt 205 is installed on the outer wall of each of the multiple synchronous pulleys 204. A concave frame 206 is fixedly connected to one side of the frame 201, and a servo motor 2 is fixedly connected to the outer side of the concave frame 206. 07. By setting up the air conditioning mechanism 2, the air force can be adjusted by opening and closing multiple baffles 203. The air force can be dynamically adjusted according to the operating temperature change of the power amplifier body 1. In this way, the cooling fan 7 will not always provide the same air force, but can be adjusted according to the actual needs of the ambient temperature. By effectively adjusting the airflow, the heat dissipation effect is optimized. When the temperature is high, the air force increases, which helps to quickly reduce the temperature of the power amplifier body 1. When the temperature is low, the air force decreases to avoid excessive air force affecting the stability of the power amplifier body 1.

[0024] Further as Figure 3 As shown, it is worth noting that multiple synchronous pulleys 204 are on the same horizontal plane. This ensures that the synchronous belt 205 is evenly transmitted between the synchronous pulleys 204, reducing the transmission inconsistency caused by different horizontal planes, and ensuring the smooth and reliable operation of the entire air regulating mechanism 2.

[0025] Further as Figure 3 As shown, it is worth noting that the output end of the servo motor 207 is fixedly connected to one of the synchronous pulleys 204 through the concave frame 206, ensuring that the servo motor 207 can drive the synchronous pulley 204 to rotate smoothly, thereby providing the original driving force for the rotation of multiple baffles 203.

[0026] As can be seen from the above working process: by setting the air conditioning mechanism 2, the air force can be adjusted by opening and closing multiple baffles 203. The air force can be dynamically adjusted according to the temperature change of the power amplifier body 1. In this way, the cooling fan 7 will not always provide the same air force, but can be adjusted according to the actual needs of the ambient temperature. By effectively adjusting the airflow, the heat dissipation effect is optimized. When the temperature is high, the air force increases, which helps to quickly reduce the temperature of the power amplifier body 1. When the temperature is low, the air force decreases to avoid excessive air force affecting the stability of the power amplifier body 1.

[0027] Further as Figure 4As shown, it is worth noting that the flow-regulating mechanism 6 includes a flow-regulating pipe 601 fixedly connected between the inlet 4 and the outlet 5. Multiple upper baffles 602 are fixedly connected to the top of the inner wall of the flow-regulating pipe 601, and multiple lower baffles 603 are fixedly connected to the bottom of the inner wall of the flow-regulating pipe 601. Multiple second rotating shafts 604 are fixedly connected between the front and rear ends of the inner wall of the flow-regulating pipe 601. Multiple fan blades 605 are rotatably connected to the outer wall of each of the multiple second rotating shafts 604, and scrapers 606 are fixedly connected to the outer sides of each of the multiple fan blades 605. By cooperating with the flow-regulating mechanism 6 and the cooling fan 7, the cooling fan... 7. While accelerating airflow, the inlet 4 and outlet 5 are connected to external refrigeration equipment. The coolant enters the slow-flow tube 601 from the inlet 4. The air blown out by the cooling fan 7 becomes cold air under the action of the coolant and acts on the power amplifier body 1, which can significantly improve the overall heat dissipation efficiency and effectively reduce the operating temperature of the power amplifier body 1. At the same time, the multiple upper baffles 602 and lower baffles 603 in the slow-flow tube 601 work together to slow down the flow rate of the coolant, making its flow more stable, increasing the residence time of the coolant in the slow-flow tube 601, improving the heat exchange efficiency, and making the heat dissipation effect more efficient.

[0028] Further as Figure 4 As shown, it is worth noting that the slow-flow tube 601 has a serpentine bend design. The serpentine bend design allows the slow-flow tube 601 to achieve a longer cooling path in a relatively limited space, thereby increasing the surface area of ​​the slow-flow tube 601 and improving the heat exchange efficiency.

[0029] Further as Figure 4 As shown, it is worth noting that the multiple upper baffles 602 and lower baffles 603 are staggered, causing the fluid to flow in a tortuous manner. This slows down the fluid flow rate and lengthens the fluid path, resulting in more efficient heat exchange. Furthermore, the scraper 606 is in contact with the surfaces of the upper baffle 602 and the lower baffle 603, effectively removing deposits and impurities from these surfaces. This prevents the accumulation of potential impurities in the coolant and keeps the flow channels clean.

[0030] This solution has the following working process: In actual use, the inlet 4 and outlet 5 are connected to external refrigeration equipment. Coolant enters the slow-flow pipe 601 from the inlet 4. Multiple upper baffles 602 and lower baffles 603 inside the slow-flow pipe 601 guide the flow, and the flow rate and direction of the coolant are regulated. The staggered distribution of the baffles helps the coolant to be evenly distributed in the pipe. When the fluid flows through, it drives the fan blades 605 to rotate, so that the scraper 606 can remove the deposits accumulated on the baffles. The air blown out by the cooling fan 7 becomes cold air under the action of the coolant and acts on the power amplifier body 1 to dissipate heat from the power amplifier body 1. The servo motor 207 can drive the synchronous pulley 204 to rotate smoothly. Under the action of the synchronous belt 205, multiple baffles 503 can rotate and open to adjust the wind force. The wind force is dynamically adjusted according to the operating temperature change of the power amplifier body 1.

[0031] In summary: By setting up the air conditioning mechanism 2 and adjusting the airflow through the opening and closing of multiple baffles 203, the airflow can be dynamically adjusted according to the operating temperature changes of the power amplifier 1. This prevents the cooling fan 7 from consistently providing the same airflow, allowing it to adjust according to the actual needs of the ambient temperature. By effectively regulating the airflow, the heat dissipation effect is optimized. When the temperature is high, the airflow increases, helping to quickly lower the temperature of the power amplifier 1; conversely, when the temperature is low, the airflow decreases, preventing excessive airflow from affecting the stability of the power amplifier 1. The use of the flow-regulating mechanism 6 in conjunction with the cooling fan 7 further enhances heat dissipation. While the fan 7 accelerates the airflow, the inlet 4 and outlet 5 are connected to external refrigeration equipment. The coolant enters the flow-slowing pipe 601 from the inlet 4. The air blown out by the cooling fan 7 becomes cold air under the action of the coolant and acts on the power amplifier body 1, which can significantly improve the overall heat dissipation efficiency and effectively reduce the operating temperature of the power amplifier body 1. At the same time, the multiple upper baffles 602 and lower baffles 603 in the flow-slowing pipe 601 work together to slow down the flow rate of the coolant, making its flow more stable, increasing the residence time of the coolant in the flow-slowing pipe 601, improving the heat exchange efficiency, and making the heat dissipation effect more efficient.
