Description

Technical Field

[0001] The present invention relates to the technical field of bandpass filters, and in particular to a bandpass filter for signal processing. Background Art

[0002] A bandpass filter is an electronic device that allows signals within a certain frequency range to pass through, while attenuating or blocking frequency signals outside the range. It is similar to a frequency window, and only signals falling within its passband can pass through without loss, while signals on both sides of the passband will be significantly suppressed. This type of filter is widely used in signal processing, communication systems, and electronic measurement. It can be used to select signals in a specific frequency band, suppress interference and noise, etc.

[0003] In order to ensure the integrity and quality of the signal and reduce the loss and interference during the transmission process, the bandpass filter should be installed as close to the power supply or signal output device as possible when in use. In a dense electrical component environment, the installation location of the filter should be carefully selected to make its input and output lines as short as possible to reduce the risk of signal attenuation and electromagnetic interference and ensure the use effect.

[0004] When the bandpass filter is working, the electronic components, power supply and signal output device inside it will generate heat. Since the bandpass filter is usually installed in an environment with dense electronic equipment and relatively limited space, the heat exchange between the bandpass filter and other electronic components is hindered to a certain extent. At the same time, as time goes by, a certain amount of dust will accumulate on the surface of the bandpass filter. This dust not only covers the heat dissipation surface, but also further aggravates the heat dissipation problem. Summary of the invention

The flow guide mechanism 6 includes a driving cylinder 606, which is filled with coolant. The driving cylinder 606 is provided with a front cavity 601, a driving cavity 602, and a rear cavity 603 from front to back. The driving cavity 602 is cylindrical. A transmission shaft 605 is coaxially fixedly provided at the output end of the motor 5. A spiral plate 604 cooperating with the driving cavity 602 is coaxially fixedly connected to the transmission shaft 605. The motor 5 drives the transmission shaft 605 and the spiral plate 604 to rotate, thereby promoting the flow of coolant inside the driving cavity 602, and sending the coolant inside the rear cavity 603 into the front cavity 601.

[0028] The front cavity 601 is connected with the driving tube 10, and the airflow circulation mechanism 11 is arranged on the driving tube 10. The outer shell 1 is provided with flow openings 3 on both sides thereof to match the airflow circulation mechanism 11. The airflow circulation mechanism 11 comprises a surrounding tube 1101 fixedly connected with the driving tube 10, the surrounding tube 1101 is fixedly connected with the outer shell 1 through a connecting plate, a driving shaft 1102 is coaxially connected to the inner part of the surrounding tube 1101, a water wheel 1103 coaxially fixedly connected to the driving shaft 1102 to match the inner cavity of the surrounding tube 1101, the driving tube 10 is located on the side of the water wheel 1103, and the horizontal height of the axis of the water wheel 1103 is different from the horizontal height of the driving tube 10, so that the coolant inside the driving tube 10 can drive the water wheel 1103 to rotate, a second blade disk 1104 is coaxially connected to the front of the surrounding tube 1101, and the second blade disk 1104 is coaxially fixedly connected to the driving shaft 1102, and the front and rear of the surrounding tube 1101 are sealed to prevent the coolant from flowing out. The coolant flows from the driving tube 10 into the interior of the surrounding tube 1101, thereby continuously impacting one side of the water wheel 1103, driving the water wheel 1103 to rotate. The rotation of the water wheel 1103 drives the driving shaft 1102 to rotate, and the driving shaft 1102 drives the second fan disk 1104 to rotate. The second fan disk 1104 drives the air flow inside the outer shell 1 to move, thereby accelerating the heat dissipation effect.

[0029] The other end of the driving tube 10 is connected to the lower cooling tube 9, and the other end of the lower cooling tube 9 is connected to the upper cooling tube 8.

The external cooling output tube 4033 and the external cooling input tube 4032 are respectively connected to the two ends of the S-shaped cooling tube 4031, so that the collected heat is sent to the inside of the S-shaped cooling tube 4031 through the coolant. The S-shaped cooling tube 4031 has a large heat dissipation area, thereby improving the heat dissipation effect. At the same time, the heat dissipation surface can be extended outward through the S-shaped cooling tube 4031, so that the heat dissipation surface is away from the narrow space, and the heat transfer is achieved, so that the heat dissipation is easy to achieve.

[0031] The driving cylinder 606 is rotatably connected to the first blade disk 7 near the bandpass filter hardware system 2, and the first blade disk 7 is coaxially fixedly connected to the transmission shaft 605.

[0033] There are gaps between the top and bottom of the housing 1 and the bandpass filter hardware system 2, and the top and bottom of the housing 1 are fixedly connected with stoppers 13 for fixing the bandpass filter hardware system 2. The existence of the gap facilitates the flow of air inside the housing 1, and the stoppers 13 fix the bandpass filter hardware system 2, thereby improving the overall stability during use.

[0034] A temperature sensor component may be provided inside the housing 1 to detect the temperature inside the housing 1 , and the motor 5 is started when the temperature inside the housing 1 exceeds a certain value.

[0035] The working principle of the present invention is as follows: when the temperature inside the housing 1 is too high, the motor 5 can be started, and the motor 5 drives the transmission shaft 605 and the spiral plate 604 to rotate, thereby promoting the flow of the coolant inside the driving chamber 602, and sending the coolant inside the rear chamber 603 into the front chamber 601, and then entering the driving tube 10 after passing through the front chamber 601. The coolant flows from the driving tube 10 into the surrounding tube 1101, thereby continuously impacting one side of the water wheel 1103, driving the water wheel 1103 to rotate, and the rotation of the water wheel 1103 drives the driving shaft 1102 to rotate, and the driving shaft 1102 drives the second fan blade disk 1104 to rotate, and the second fan blade disk 1104 drives the airflow inside the housing 1 to move, thereby accelerating the heat dissipation effect;

[0036] When the motor 5 drives the transmission shaft 605 to rotate, the transmission shaft 605 will drive the first blade disk 7 to rotate, and the first blade disk 7 will push the airflow inside the housing 1 to flow horizontally, thereby reducing the range of the air flow dead angle and ensuring the heat dissipation effect;

[0037] The coolant flows from the driving tube 10 into the lower cooling tube 9, and then flows from the lower cooling tube 9 into the upper cooling tube 8. The surface heat of the bandpass filter hardware system 2 is collected through the lower cooling tube 9 and the upper cooling tube 8, and the collected heat is sent to the inside of the S-shaped cooling tube 4031 through the coolant. The S-shaped cooling tube 4031 has a large heat dissipation area, thereby improving the heat dissipation effect. At the same time, the heat dissipation surface can be extended outward through the S-shaped cooling tube 4031, so that the heat dissipation surface is away from the narrow space, and the heat transfer is realized, thereby facilitating heat dissipation. The external cooling output tube 4033, the external cooling input tube 4032 and the S-shaped cooling tube 4031 are all wrapped with a protective bag 402, and the protective bag 402 is responsible for reducing the impact of the external environment on the external cooling output tube 4033, the external cooling input tube 4032 and the S-shaped cooling tube 4031.
