[0026] In this embodiment, the moving component 7 includes a bracket 71, which is fixedly mounted on the top of the partition 2. A servo motor 72 is fixedly mounted on the top of the bracket 71.

[0027] In this embodiment, the heat insulation shell 81 is fixedly installed at the other end of the U-shaped tube 5. The heat insulation shell 81 is configured as a hexagonal prism, and several cooling components 9 are set on the six sides of the hexagonal prism. The interior of the heat insulation shell 81 is hollow so that the heat insulation shell 81 can connect the U-shaped tube 5 and the air inlet pipe 82.

One end of the air inlet pipe 82 passes through the inner wall of one side of the box body 1 and is placed outside the box body 1. The interior of the heat insulation shell 81 is connected to the interior of the U-shaped tube 5. Rock wool insulation layers are fixedly installed on the inner wall of the heat insulation shell 81 and the bottom end of the partition 2 to achieve heat preservation of the heat insulation shell 81. The partition 2 cooperates with the box body 1 coated with heat insulation paint to insulate the space at the bottom end of the partition 2, thereby preventing the heat released by the hot end of the semiconductor cooling chip 92 from heating the space at the top of the partition 2 through the partition 2.

[0028] In a further embodiment, the cooling component 9 includes a through groove 91, which is formed on the surface of the heat insulation shell 81. A semiconductor cooling chip 92 is fixedly disposed on the inner wall of the through groove 91.

The thermally conductive silicone grease increases the contact surface and improves the heat dissipation effect. The surface of the first heat sink 93 is connected to the inner wall of the heat insulation shell 81.

[0029] In a further embodiment, a connecting cylinder 83 is fixedly provided at one end of the air intake pipe 82, and a sealing ring is embedded at one end of the air intake pipe 82.

One side of the filter shell 84 is slidably connected to one end of the sealing ring. After installation, the filter shell 84 presses the sealing ring to seal the gap between the air intake pipe 82 and the connecting cylinder 83. An air intake hole 85 is provided on the other side of the filter shell 84. A first dustproof net is fixedly provided on the inner wall of the air intake hole 85.

Both ends of the two positioning tubes 86 penetrate the inner wall of the filter shell 84 and are placed on the outside of the filter shell 84. The top and bottom surfaces of the two positioning tubes 86 are threadedly connected with sealing caps 87. One end of each sealing cap 87 is fixedly provided with a buffer pad. When the buffer pad slides down the inner wall of the positioning tube 86 into the diatomaceous earth moisture-absorbing rod 89, it abuts against the diatomaceous earth moisture-absorbing rod 89 to buffer it. The surface of the middle section is provided with dehumidification grooves 88. The interior of the two dehumidification grooves 88 is connected to the interior of the filter shell 84. The inner walls of the two positioning tubes 86 are slidably connected with diatomaceous earth moisture-absorbing rods 89. One end of the two diatomaceous earth moisture-absorbing rods 89 is slidably connected to one end of the two buffer pads respectively. The diatomaceous earth moisture-absorbing rods 89 come into contact with the airflow passing through the filter shell 84 through the dehumidification grooves 88, thereby drying the airflow and preventing the air nozzle 62 from blowing humid airflow onto the trunk amplifier body 4, which helps to extend the service life of the trunk amplifier body 4.

[0031] In this embodiment, the inner walls of the housing 1, the U-shaped tube 5, and the air inlet pipe 82 are all coated with heat-insulating paint to prevent the heat released from the hot end of the semiconductor cooling chip 92 from heating the space at the top of the partition 2 through the housing 1, partition 2, and U-shaped tube 5. A sealing cover 16 is hinged to the top of the housing 1. An air inlet 10 is provided on the front of the housing 1, and a second fan is fixedly installed on the inner wall of the air inlet 10. An air outlet 11 is provided on the back of the housing 1. Dust covers 12 are fixedly installed on both the front and back of the housing 1 to prevent dust from entering the interior of the housing 1 through the air inlet 10 and the air outlet 11, thereby preventing dust from adhering to the surface of the second heat sink 94. Dust accumulation will... To reduce the heat dissipation effect of the second heat sink 94, one dust cover 12 is fitted outside the air inlet 10, and the other dust cover 12 is fitted outside the air outlet 11. An exhaust groove 13 and several equally spaced wiring holes 14 are respectively opened on one side of the housing 1 for leading out the wires of the trunk amplifier body 4. A second dustproof mesh is fixedly installed on the inner wall of the exhaust groove 13. Rubber plugs 15 are slidably connected to the inner walls of several wiring holes 14. While rotating, the rubber plugs 15 are pressed in, causing the rubber plugs 15 to block the wiring holes 14 and achieve a seal. A wire hole is opened in the middle of several rubber plugs 15, and the guide hole is in contact with the wires of the trunk amplifier body 4.

[0032] The servo motor 72 and the semiconductor cooling chip 92 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0033] Working principle and process of a high-efficiency trunk amplifier heat dissipation and protection chassis: The first fan, servo motor 72, and semiconductor cooling chip 92 are activated. The first fan generates airflow, which sequentially passes through the intake hole 85, filter shell 84, connecting cylinder 83, and air inlet pipe 82 into the interior of the heat insulation shell 81. The cold end of the semiconductor cooling chip 92 exchanges heat with the airflow through thermal grease and the first heat sink 93, thereby reducing the temperature of the airflow. The cooled airflow passes through the U-shaped tube 5 and the telescopic rubber tube 63 and is ejected from the air nozzle 62, blowing on the trunk amplifier body 4 at the top of the aluminum base 3 to achieve rapid heat dissipation of the trunk amplifier body 4. The airflow is finally discharged through the exhaust groove 13. The servo motor 72 drives the drive block 74 to rotate through the transmission rod 73. The rotating drive block 74 drives the first slide rod 75 and the first collar. 76 rotates around the transmission rod 73. At this time, the first ring 76 and the first slide rod 75 will rotate relative to each other through the bearing, and the second ring 78 and the second slide rod 79 will rotate relative to each other through the bearing. Therefore, the first ring 76 applies a force to the second slide rod 79 through the connecting rod 77 and the second ring 78, causing the second slide rod 79 and the bracket 71 to swing back and forth around the pivot. The bracket 71 drives the air nozzle 62 to swing back and forth. Compared with only blowing the middle part of the trunk amplifier body 4, the air nozzle 62 blows one end, the middle and the other end of the trunk amplifier body 4 in sequence, increasing the blowing range and improving the heat dissipation efficiency. It should also be emphasized that the aluminum base 3 increases the heat exchange area between the bottom of the trunk amplifier body 4 and the airflow, further improving the heat dissipation efficiency. The diatomaceous earth moisture absorber 89 comes into contact with the airflow passing through the filter housing 84 via the dehumidification tank 88, thereby drying the airflow and preventing the humid airflow from contacting the trunk amplifier body 4, which helps extend the service life of the trunk amplifier body 4. When the diatomaceous earth moisture absorber 89 needs to be replaced, first rotate the sealing cover 87 located at the bottom to move the sealing cover 87 downward, separating the sealing cover 87 from the positioning tube 86. The diatomaceous earth moisture absorber 89 slides out due to its own weight. Then, rotate the sealing cover 87 back and rotate the sealing cover 87 located at the top, sliding the diatomaceous earth moisture absorber 89 down along the inner wall of the positioning tube 86 until the diatomaceous earth moisture absorber 89 is held in place by the buffer pad. Finally, rotate the top sealing cover 87 back to complete the replacement of the diatomaceous earth moisture absorber 89. The diatomaceous earth moisture absorber 89 can be replaced without disassembling the filter housing 84, which is convenient to use.
