Description

Technical Field

[0001] This application relates to the field of radio frequency coaxial relay technology, and more specifically, to a heat dissipation component and a radio frequency coaxial relay. Background Technology

[0002] A radio frequency (RF) coaxial relay is a switching relay specifically designed for high-frequency signal transmission; it is also known as an RF switch or microwave switch. Its core function is to achieve precise switching of RF signals between multiple transmission paths through electromagnetic or solid-state actuation mechanisms, while maintaining signal integrity and stability.

[0003] High-power RF coaxial relays require a certain amount of heat dissipation. Because high-power RF coaxial relays generate high temperatures during operation, especially in hot environments, it is difficult for internal heat to be released to the outside, which can easily cause the internal temperature of the casing to rise, resulting in limited performance and accelerated aging of internal components, thus reducing the lifespan of the device. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a heat dissipation component and an RF coaxial relay, which aims to improve the problem that the high-power RF coaxial relay cannot dissipate heat in time, which causes the internal temperature of the housing to rise, resulting in limited use and accelerated aging of internal components, thus reducing the lifespan of the device.

[0005] This application provides a heat dissipation component, including a housing, a heat dissipation section, and an air intake section.

[0006] The heat dissipation part includes a bottom cover, foot plates, a heat dissipation fan, an exhaust pipe, and a second solenoid valve. The bottom cover is fixed to the bottom of the housing. The foot plates are located on the lower outer side of the bottom cover. The heat dissipation fan is installed inside the bottom cover. One end of the exhaust pipe scrapes against the bottom cover and the side wall of the housing. The second solenoid valve is installed in conjunction with the exhaust pipe. The air intake section includes an air intake cover, an air intake pipe, and a first solenoid valve. The air intake cover is connected and installed on the top of the housing. One end of the air intake pipe passes through the air intake cover and is located inside the air intake cover. The first solenoid valve is installed in conjunction with the air intake pipe.

[0007] The heat dissipation assembly also includes a flow guide shell, which is installed at the bottom of the bottom cover. The heat dissipation fan exhausts air into the flow guide shell, and the flow guide shell is provided with a first flow guide port and a second flow guide port for upward flow at both ends.

[0008] In one specific implementation, the upper surface of the flow guide shell is provided with a communication port that is installed in conjunction with a cooling fan.

[0009] In one specific implementation, filter covers are provided at the top openings of both the first and second flow guide ports.

[0010] In one specific implementation, a filter cavity communicating with the outside is provided on one side of the inside of the air inlet shroud, and a filter layer is provided inside the filter cavity. One end of the air inlet pipe passes through and communicates with the inside of the filter cavity.

[0011] In one specific implementation, the filter layer includes a filter screen and a filter cotton layer, wherein the filter screen is installed on the outside of the filter cavity and the filter cotton layer is disposed inside the filter cavity.

[0012] In one specific implementation, the heat dissipation section further includes a reinforcing plate, which is fixedly connected to the bottom cover and the foot plate.

[0013] This application also provides a radio frequency coaxial relay, including the heat dissipation component described above.

[0014] Beneficial effects: This application provides a heat-conducting and heat dissipation component and a radio frequency coaxial relay. The circulating air carries the heat generated inside the housing to the exhaust pipe and into the bottom cover. The cooling fan then exhausts the heat from inside the bottom cover to the outside, achieving rapid cooling of the housing's interior. When the cooling fan is not running, both the second and first solenoid valves are closed, preventing external moisture from entering the housing and providing good protection for the internal electronic components.

[0018] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0019] Please see Figures 1-3 This application provides a heat dissipation component, including a housing 1, a heat dissipation part 2, and an air inlet part 3.

[0020] The heat dissipation section 2 includes a bottom cover 21, foot plate 22, cooling fan 23, exhaust pipe 24, and second solenoid valve 25. The bottom cover 21 is fixed to the bottom of the housing 1. The foot plate 22 is located on the outer side below the bottom cover 21. The cooling fan 23 is installed inside the bottom cover 21. One end of the exhaust pipe 24 scrapes against the bottom cover 21 and the side wall of the housing 1. The second solenoid valve 25 is installed in conjunction with the exhaust pipe 24. The air intake section 3 includes an air intake cover 31, an air intake pipe 32, and a first solenoid valve 33. The air intake cover 31 is connected and installed at the top of the housing 1. One end of the air intake pipe 32 passes through the air intake cover 31 and is located inside the air intake cover 31. The first solenoid valve 33 is installed in conjunction with the air intake pipe 32.

[0021] While the cooling fan 23 is running, both the second solenoid valve 25 and the first solenoid valve 33 are open. External air enters the housing 1 through the inlet pipe 32, carrying away the heat generated inside the housing 1 through the outlet pipe 24 into the bottom cover 21. The cooling fan 23 then exhausts the heat from the bottom cover 21, thus rapidly cooling the interior of the housing 1 and allowing the RF coaxial relay to operate continuously in a suitable temperature environment. When the cooling fan 23 is not running, both the second solenoid valve 25 and the first solenoid valve 33 are closed, preventing external moisture from entering the housing 1 and providing good protection for the electronic components inside.

[0022] The heat dissipation assembly also includes a flow guide shell 4, which is installed at the bottom of the base shell 21. The cooling fan 23 exhausts air into the flow guide shell 4. The flow guide shell 4 has a first flow guide port 41 and a second flow guide port 42 at both ends for upward airflow. The upper surface of the flow guide shell 4 has a communication port 43 that mates with the cooling fan 23. The air exhausted from the cooling fan 23 enters the flow guide shell 4 and is finally discharged from the first flow guide port 41 and the second flow guide port 42 at both ends of the flow guide shell 4 to the cable interface of the coaxial relay. The circulating air can reduce the temperature at the interface.

[0023] Specifically, filter covers are provided at the top openings of the first guide port 41 and the second guide port 42 to reduce dust entering the interior of the guide shell 4 when the cooling fan 23 is not running.

[0024] In the above specific embodiment, a filter cavity communicating with the outside is provided on one side of the air inlet housing 31. A filter layer is provided inside the filter cavity, and one end of the air inlet pipe 32 passes through and communicates with the inside of the filter cavity. The filter layer includes a filter screen 34 and a filter cotton layer 35. The filter screen 34 is installed on the outside of the filter cavity, and the filter cotton layer 35 is disposed inside the filter cavity. The filter screen 34 and the filter cotton layer 35 are used to filter out dust and moisture in the air, making the gas entering the housing 1 cleaner and drier.

[0025] Furthermore, the heat dissipation part 2 also includes a reinforcing plate 26, which is fixedly connected to the bottom cover 21 and the foot plate 22.

[0026] This application also provides a radio frequency coaxial relay, including the aforementioned heat dissipation component. This heat dissipation component is suitable for various high-power radio frequency coaxial relays.

[0027] It should be noted that the specific models and specifications of the cooling fan 23, the second solenoid valve 25, and the first solenoid valve 33 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, and therefore will not be described in detail. The power supply and principle of the cooling fan 23, the second solenoid valve 25, and the first solenoid valve 33 are clear to those skilled in the art, and will not be described in detail here.

[0028] The working principle of this heat dissipation component and RF coaxial relay is as follows: During use, while the cooling fan 23 is running, both the second solenoid valve 25 and the first solenoid valve 33 are open. External air enters the housing 1 through the air inlet pipe 32. The flowing air carries away the heat generated inside the housing 1 to the air outlet pipe 24, which then enters the bottom cover 21. The cooling fan 23 then exhausts the heat from inside the bottom cover 21 to the outside, thereby rapidly cooling the heat inside the housing 1 and enabling the RF coaxial relay to operate continuously in a suitable temperature environment. When the cooling fan 23 is not running, both the second solenoid valve 25 and the first solenoid valve 33 are closed, preventing external moisture from entering the housing 1 and providing good protection for the electronic components inside the housing 1.

[0029] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
