Description

Technical Field

[0001] This utility model relates to the technical field of external heat dissipation equipment, specifically an external heat dissipation device for a power amplifier. Background Technology

[0002] A power amplifier is an amplifier that can generate maximum power output to drive a load under a given distortion rate. It generally consists of a chassis and functional components housed inside the chassis. During use, power amplifiers are usually cooled by external heat dissipation devices to ensure stable operation.

[0003] Existing external heat dissipation devices for power amplifiers suffer from various drawbacks due to differences in amplifier models, widths, and dimensions, resulting in inconsistent mounting hole spacings and making universal heat dissipation devices difficult to implement. Furthermore, these devices typically lack adjustment capabilities, making them incompatible with amplifiers of different widths. Finding suitable heat dissipation devices for non-standard sized amplifiers becomes challenging, reducing device compatibility. Additionally, the fan, a core component of the heat dissipation device, is usually located on one side of the amplifier, leaving blind spots and insufficient heat dissipation coverage. This ineffective dissipation of heat from the amplifier's exterior, coupled with the high temperatures generated during continuous operation, can damage internal components and reduce the amplifier's stability during extended use.

[0024] 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.

[0025] Please see Figure 1-4 As shown, an external heat dissipation device for a power amplifier includes a base 1, a first mounting bracket 2 on the top of the base 1, a second mounting bracket 3 on the top of the first mounting bracket 2, a fan 4 for cooling the power amplifier mounted on the outer side of the first mounting bracket 2, the fan 4 being powered by an external power supply, and a control switch integrated on its outer side; an amplifier body 5 (a slang term for a power amplifier) ​​is disposed on the inner side of the first mounting bracket 2 and the second mounting bracket 3; a flow guiding component 11 is disposed on the inner wall of the first mounting bracket 2, and an exhaust component 12 is disposed on the inner wall of the second mounting bracket 3.

[0026] An adjustment component 6 is located at the bottom of the base 1. A transmission component 7 and a fixing component 13 are located on the outside of the adjustment component 6. Two sets of movable seats 8 are located on the outside of the transmission component 7. Guide components 9 are located on the outside of both sets of movable seats 8. Two sets of connecting frames 10 are located on the outside of the movable seats 8. Their bottoms are fixedly connected to the outside of the movable seats 8 to conduct the kinetic energy of the movable seats 8 when they move, thereby driving the two sets of mounting frames to complete the corresponding movements. The tops of the two sets of connecting frames 10 are fixedly connected to the outside of the first mounting frame 2 and the second mounting frame 3, respectively.

[0027] The adjustment assembly 6 includes a rotating shaft 61 that rotates at the bottom of the base 1. One end of the rotating shaft 61 is fixedly connected to a handle 62 for driving the rotating shaft 61 to rotate and transmitting kinetic energy through the rotating shaft 61. A fixing plate 63 is fixedly connected to the bottom of the base 1, which is located above the handle 62, and the inner wall of the fixing plate 63 is rotatably connected to the outer side of the rotating shaft 61.

[0028] The transmission assembly 7 includes a transmission block 71 fixed to the outside of the rotating shaft 61. Two connecting rods 72 are rotatably connected to the bottom of the transmission block 71. The connecting rods 72 are L-shaped. When the transmission block 71 rotates, the connecting rods 72 gradually retract or expand, and drive the movable seat 8 to complete the corresponding movement through the other end. The other end of the connecting rods 72 is rotatably connected to the bottom of the movable seat 8.

[0029] The guide assembly 9 includes a guide block 91 fixed to the top of the movable seat 8. A limiting groove 92 is provided at the bottom of the base 1. The outer side of the guide block 91 is slidably connected to the inner wall of the limiting groove 92. When the movable seat 8 moves, it will slide along the inner side of the limiting groove 92 with the guide block 91. The limiting groove 92 can restrict the degree of freedom of movement of the movable seat 8, ensure that it moves in a straight line along the limiting groove 92, and prevent the movable seat 8 from deviating when it moves.

[0030] The fixing component 13 includes a plug rod 131 that rotates to the outside of the handle 62. The inner wall of the fixing plate 63 is provided with a plurality of slots 132 in a ring. The outer side of the plug rod 131 is engaged with the inner side of the slot 132. The plug rod 131 is inserted into the inner side of the slot 132 by rotation, locking the position of the handle 62 and preventing the mounting bracket from loosening due to vibration or misoperation after installation. The top of the plug rod 131 is a ball head structure and is made of elastic material, slightly larger than the hole diameter of the slot 132, so that the plug rod 131 will not fall out of the slot 132 naturally.

[0031] The airflow guiding assembly 11 includes a diversion channel 111 formed on the inner wall of the first mounting bracket 2, which is used to disperse the concentrated airflow generated by the fan 4 into multiple airflows and guide them to each airflow guiding channel 112 to expand the area covered by the wind. The inner side of the diversion channel 111 is connected to multiple sets of airflow guiding channels 112. The wind flows along the airflow guiding channels 112 and carries away the heat outside the power amplifier.

[0032] The exhaust assembly 12 includes multiple sliding blocks 121 fixed to the bottom of the second mounting bracket 3, which are used to block the flow of air and guide the air upward into the exhaust duct 122 to avoid air loss. At the same time, when the distance between the first mounting bracket 2 and the second mounting bracket 3 is adjusted, they slide along the inner wall of the guide duct 112 to improve the stability of the connection between the two mounting brackets. Multiple sets of exhaust ducts 122 are vertically opened through the inner wall of the second mounting bracket 3 to discharge the vertical airflow guided by the sliding blocks 121, forming a directional air duct to avoid hot air backflow. The outer side of the sliding block 121 is slidably connected to the inner wall of the guide duct 112.

[0033] Working principle: When a heat dissipation device needs to be installed during use, first place the amplifier body 5 at the top midpoint of the first mounting bracket 2 and the second mounting bracket 3. Then turn the handle 62, which drives the transmission block 71 through the rotating shaft 61, and at the same time drives the two connecting rods 72 connected to its outer side to rotate. As the connecting rods 72 rotate, they gradually retract, causing the two sets of moving seats 8 to gradually approach the first mounting bracket 2 and the second mounting bracket 3 through their respective connected connecting brackets 10, and engage with the outer side of the amplifier body 5. Then insert the plug rod 131 into the corresponding slot 132 to complete the installation and fixation. When the heat dissipation device is working, the fan 4 starts first, and the blown air is guided through the diversion groove 111 to the multiple sets of guide grooves 112 connected to it. The air flows along the guide grooves 112, carrying away the heat of the power amplifier that is attached to the guide grooves 112. When the air reaches the sliding block 121, the sliding block 121 will block the flow of the air and guide the air upward into the exhaust groove 122. Then the air carrying the heat is blown out from the exhaust groove 122, achieving efficient heat dissipation.
