Description

Technical Field

[0001] This utility model relates to the field of radio frequency switch box technology, and in particular to a wind-cooled radio frequency switch box. Background Technology

[0002] An RF switch box is a device used to route RF, IF, or microwave signals between multiple available signal paths. It can switch between different RF signal paths, enabling signal selection and routing. The electronic components within the RF switch box generate heat during operation; therefore, the RF switch box needs to have sufficient heat dissipation capabilities to maintain the device's normal operating temperature.

[0003] Chinese Patent CN215682990U discloses a high-frequency radio frequency switch box with high air-cooling efficiency, including a box body, a support frame, a support base, a cooling fan, and a limiting inner frame. The support frame is fixedly installed inside the box body, and the support base is slidably installed inside the slide groove. Multiple sets of heat sinks are fixedly installed on one side of the support base, and a fan base is slidably installed inside the arc-shaped groove. The cooling fan is fixedly installed inside the fan base. The box body has a support frame and a support base, and the support base can slide on the support frame to adjust for radio frequency components of different sizes. The support base has heat sinks arranged in a pattern, and the fan base and cooling fan are also located inside the heat sinks. Driven by a lead screw, the radio frequency components are cooled from different positions on the heat sinks, resulting in good heat dissipation. The support base has a wire groove and a limiting inner frame inside, which can pull the radio frequency cables to prevent them from piling up in one place, causing poor air circulation, and thus affecting the heat dissipation effect.

[0004] However, the above technical solution has the following shortcomings: the RF switch box needs to be driven by a lead screw to rotate, so that the fan base can drive the cooling fan to move horizontally continuously to dissipate heat from the RF components at different locations. This results in a vacuum period where some RF components cannot be properly cooled, thus reducing the heat dissipation effect. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an air-cooled RF switch box, which can greatly improve the heat dissipation effect of the RF switch module, avoid the vacuum period where heat dissipation cannot be stable, and ensure the service life of the equipment.

[0006] The present invention provides a wind-cooled RF switch box, comprising a box body and a heat dissipation device. The box body has an air inlet duct, and three mounting brackets are provided inside the box body, each mounting bracket holding an RF switch module. The heat dissipation device includes a mounting plate inside the air inlet duct, a cooling fan mounted on the mounting plate, and dustproof mechanisms and connecting frames respectively located at both ends of the air inlet duct. The connecting frame has multiple rectangular arrayed air jets. The dustproof mechanism includes a first frame on the box body, a first dustproof mesh on the first frame, and a fixing component on the first frame.

[0007] Preferably, the housing is provided with four horizontally distributed sliding grooves, and the fixing components include four symmetrically distributed locking blocks on the first frame, insert blocks slidably connected inside the sliding grooves, and springs at both ends respectively provided on the insert blocks and the sliding grooves; the locking blocks are provided with limiting grooves for the insert blocks to be inserted.

[0008] Preferably, the insert block is provided with a guide rod, which is slidably disposed inside the slide groove, and a spring is sleeved on the guide rod.

[0009] Preferably, pull plates are provided on both sides of the insert blocks, and the pull plates are slidably connected to the slide grooves.

[0010] Preferably, the housing is provided with an air outlet, and the air outlet is provided with two second frames, and the second frames are provided with second dustproof nets.

[0011] Preferably, the box body is provided with a box cover, and four fixing bolts arranged in a rectangular array are provided through the box cover. The fixing bolts are threaded to the box body, and the fixing bolts and the box cover abut against each other.

[0012] Preferably, the housing is provided with multiple heat dissipation fins, and the portion of the heat dissipation fins located inside the housing is interspersed in the gaps of the mounting bracket.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. This utility model uses a heat dissipation device to deliver cold air from the outside into the interior of the connecting frame through the air inlet pipe, and then ejects it from various jet pipes on the connecting frame. At the same time, the design of the mounting frame and the installation position of the RF switch module allows the cold air to blow onto each component of the RF switch module simultaneously. In conjunction with the heat dissipation fins, the air exchanges heat with the heat generated by the RF switch module during operation, thus achieving a good heat dissipation effect on the interior of the enclosure.

[0015] 2. This utility model can prevent dust from entering the interior of the housing by setting a first dustproof net and a second dustproof net, ensuring the normal operation of the equipment. At the same time, the set fixing components can quickly install and remove the first dustproof net, so as to clean and replace the first dustproof net. The operation is simple and convenient.

[0022] like Figures 1-5 As shown in the figure, the air-cooled RF switch box proposed in this embodiment includes a box body 1 and a heat dissipation device; an air inlet pipe 2 is provided on the box body 1, and three mounting brackets 7 are provided inside the box body 1, with RF switch modules 8 mounted on the mounting brackets 7.

[0023] The heat dissipation device includes a mounting plate 3 installed inside the air inlet duct 2, a heat dissipation fan 4 installed on the mounting plate 3, and dustproof mechanisms and connecting frames 5 installed at both ends of the air inlet duct 2 respectively; the connecting frame 5 is provided with multiple rectangular arrays of air jet pipes 6, and the dustproof mechanism includes a first frame 9 installed on the housing 1, a first dustproof net 10 installed on the first frame 9, and a fixing component installed on the first frame 9.

[0024] The cooling fan 4 draws cool air from the outside through the air inlet duct 2 into the interior of the connecting frame 5, and then ejects it from the various jet pipes 6 on the connecting frame 5. This allows the cool airflow to simultaneously reach all angles inside the enclosure 1, thus providing good air cooling for all components of the RF switch module 8 on the mounting frame 7. The airflow also exchanges heat with the RF switch module 8 generated during operation, and then is discharged from the enclosure 1 with the airflow. This achieves good heat dissipation inside the enclosure 1. Combined with the first dustproof net 10, dust can be prevented from entering the interior of the enclosure 1 through the air inlet duct 2, ensuring the normal operation of the equipment.

[0025] The housing 1 is provided with four horizontally distributed sliding grooves. The fixing components include four symmetrically distributed locking blocks 11 on the first frame 9, insert blocks 13 slidably connected inside the sliding grooves, and springs 14 respectively set on the insert blocks 13 and the sliding grooves at both ends. The locking blocks 11 are provided with limiting grooves 12 for the insert blocks 13 to be inserted into. The insert blocks 13 are provided with guide rods 15, which are slidably set inside the sliding grooves. The springs 14 are sleeved on the guide rods 15. Pull plates 16 are provided on both sides of the insert blocks 13, and the pull plates 16 are slidably connected to the sliding grooves.

[0026] When the equipment needs to be disassembled after prolonged use to clean the first dust filter 10, the insert block 13 can be pulled by the pull plate 16 to move it away from the first frame 9 until it disengages from the limiting groove 12 of the locking block 11, at which point the first frame 9 can be removed. When reinstalling, the pull plate 16 is pulled again to compress the spring 14, which then fits into the port of the air inlet duct 2 through the first frame 9. The pull plate 16 is then released, and the insert block 13 moves along the slide groove under the elastic force of the spring 14 until it is inserted into the interior of the locking block 11, thus completing the fixed installation. The operation is simple and convenient. Furthermore, the guide rod 15 not only prevents the insert block 13 from disengaging from the slide groove but also guides the extension and retraction of the spring 14, preventing the spring 14 from bending or twisting and ensuring its service life. It has good practicality.

[0027] like Figure 1 , Figure 3 and Figure 4As shown in the figure, this embodiment proposes a wind-cooled RF switch box. Compared with the first embodiment, in this embodiment, the box 1 is provided with an air outlet, and the air outlet is provided with two second frames 17. The second frames 17 are provided with second dustproof nets 18. The box 1 is provided with multiple heat dissipation fins 21. The heat dissipation fins 21 located inside the box 1 are interspersed in the gaps of the mounting brackets 7. The air outlet is used to ensure the normal flow of gas inside the box 1 and ensure good heat dissipation effect. The second dustproof nets 18 can prevent a small amount of dust from entering the interior of the box 1 from the air outlet. The mounting brackets 7 are evenly distributed inside the box 1, and each component of the RF switch module 8 is installed in an orderly manner on the mounting brackets 7. This can not only ensure smooth airflow, but also facilitate the installation and maintenance of each component. At the same time, the heat dissipation fins 21 provide auxiliary heat dissipation and improve the heat dissipation efficiency.

[0028] like Figure 4 As shown, a cover 19 is provided on the enclosure 1. Four rectangular array of fixing bolts 20 are arranged through the cover 19. The fixing bolts 20 are threaded onto the enclosure 1. The fixing bolts 20 and the cover 19 abut against each other. The cover 19 is used to protect the radio frequency switch module 8 inside the enclosure 1. The cover 19 is fastened to the enclosure 1 by the fixing bolts 20. When it is necessary to open the cover 19, the fixing bolts 20 can be removed.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
