Description

Technical Field

[0001] This invention relates to the field of radar technology, specifically to a wideband electromagnetic shielded radar transmitting intermediate frequency box structure. Background Technology

[0002] Radar is a device for detecting the location of targets and is widely used in target location monitoring, terrain monitoring, and other fields. Computers can draw target location coordinates and terrain structure maps based on radar information. With the advancement of measurement technology, radar and quantum technology are increasingly being combined. Quantum-enhanced radar is an improved version of traditional electromagnetic radar and is highly similar to traditional radar. Both use electromagnetic waves to detect targets. When the radar transmitter is working, it receives the intermediate frequency modulated signal generated by the signal source. Then, the intermediate frequency signal is passed through the output mixer to generate a small radio frequency signal. Subsequently, the small radio frequency signal is pre-amplified by an isolator and a driver amplifier, and then passed through the final stage power amplifier to output a high-power signal to the antenna for transmission. Electromagnetic waves are easily generated between the various modules in the radar transmitter. Electromagnetic waves need to be shielded to prevent electromagnetic wave leakage from being detected or the modules from being interfered with by external electromagnetic waves, and also to prevent electromagnetic waves between the various modules from interfering with each other.

[0003] The existing radar housing structure has the following drawbacks:

[0004] Prior art CN106093880A discloses a field surveillance radar system transmitting device, which includes a box-shaped housing and a top cover for sealing the housing opening. The housing cavity forms a receiving cavity for accommodating components. The components include at least a waveguide synthesizer, a coupler, and a filter arranged sequentially. The adjacent mating surfaces of the waveguide synthesizer, coupler, and filter are all flange faces and form a flange-fixed fit with each other. Each flange face is embedded with a shielding sealing ring to enhance the electromagnetic shielding capability at that location. This invention improves the assembly and maintenance efficiency of the device while effectively reducing or even avoiding microwave signal leakage problems; it has a high structural compactness, a smaller device size, and effectively improves the ease of maintenance.

[0005] The aforementioned technologies are insufficient for optimizing heat dissipation. Radars generate a significant amount of heat, and failure to dissipate this heat in a timely manner can affect their functionality. While air cooling can reduce the internal heat of the radar, under prolonged high-power operation, the small heat dissipation area of ​​the module makes it difficult to dissipate heat in a timely manner. Therefore, a wideband electromagnetic shielded radar transmitting intermediate frequency box structure that can increase the heat dissipation area, optimize the heat dissipation structure, and improve the heat dissipation capacity is needed to solve this problem.

[0014] Preferably, a shielding plate 2 is movably installed on the outer side of the guide plate, and the shielding plate 2 is located between two fixed frames 2. A through opening 3 is provided on one side of the shielding plate 2. A conductive rubber pad 2 is installed on the outer side of the shielding plate 2. A fixed frame 1 is installed on the left side of the shielding plate 2, and the fixed frame 1 is located on the outer side of the guide plate. A bolt 2 is installed through the top of the fixed frame 1.

[0015] Preferably, a bolt three is installed through the top of the fixed frame two. The movable heat conduction mechanism includes a guide rod, a heat conduction rod two, a bolt four, a heat conduction silicone pad two, a heat dissipation fin two, and a heat conduction silicone pad three. The guide rod is installed on the back of the fixed frame two. The heat conduction rod two is movably installed on the outside of the guide rod. Bolt four is symmetrically installed through both sides of the heat conduction rod two. A heat conduction silicone pad two is installed at the bottom of the heat conduction rod two. Multiple heat dissipation fins two are installed at the top of the heat conduction rod two. A heat conduction silicone pad three is installed on the back of the heat conduction rod two and the heat dissipation fins two, and the heat conduction silicone pad three is in contact with the adjacent shielding plate one behind it.

[0016] Preferably, the method of using the broadband electromagnetic shielded radar transmitting intermediate frequency box structure is as follows:

[0017] S1. Place each module of the radar transmitter into the shielding box in the order of connection. Place each module in a single section separated by shielding plate one and shielding plate two. Then move the position of shielding plate two left and right so that the module with high heat generation occupies a large space and the module with low heat generation occupies a small space.

[0018] S2. Then, the thermally conductive limiting plate is pressed against the module under the compression of the spring, so that the thermally conductive silicone pad on the front of the thermally conductive limiting plate contacts the module, which facilitates the front and rear direction limitation of the module. At the same time, the heat of the module is transferred to the shielding plate one more quickly, and then to the shielding box, and is dissipated through the heat dissipation fins one.

[0019] S3. Next, move the fixed frame two so that the heat conduction rod two moves above each module. Then move the heat conduction rod two down so that the heat conduction silicone pad two contacts the top of the module, limit the top of the module, and allow the heat from the top of the module to be transferred to the guide plate through the heat conduction rod two, then to the shielding plate one, then to the shielding box, and then to the heat dissipation fin one.

[0020] S4. Then place the shielding cover on top of the shielding box.

[0021] Preferably, step S4 further includes the following steps:

[0022] S41. The temperature sensor detects the internal temperature of the shielding box. When the temperature reaches the set value, the controller controls the fan to blow air into the shielding box, allowing outside air to enter the shielding box through the second cutoff waveguide ventilation window, and then the hot air inside the shielding box is discharged from the shielding box through the first cutoff waveguide ventilation window.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention moves the second heat-conducting rod above each module, and then moves the second heat-conducting rod down so that the second heat-conducting silicone pad contacts the top of the module, limiting the top of the module. The modules of the radar transmitter do not need to be fixed with bolts, making the module fixing method faster and more convenient, reducing the amount of operation, and allowing the heat from the top of the module to be transferred to the guide plate through the second heat-conducting rod, then to the shielding plate, then to the shielding box, and finally to the heat dissipation fins, resulting in fast heat dissipation.

[0025] 2. This invention places the various modules of the radar transmitter into a shielded box in the order of connection. Each module is placed in a single section separated by shielding plate one and shielding plate two. Then, the position of shielding plate two is moved left and right so that the modules with high heat generation occupy a large space and the modules with low heat generation occupy a small space. This allows for reasonable adjustment of the space occupied by the modules according to their heat generation, making the heat dissipation of each module more reasonable. At the same time, shielding plate one can move up and down, and heat conduction rod two can move left and right, which facilitates the installation, disassembly and maintenance of each radar module.

[0026] 3. This invention optimizes the heat dissipation method and has a simple structure. The temperature sensor detects the internal temperature of the shielding box. When the temperature reaches the set value, the controller controls the fan to blow air into the shielding box, allowing outside air to enter the shielding box through the second cutoff waveguide ventilation window. Then, the hot air inside the shielding box is discharged through the first cutoff waveguide ventilation window. The air discharged from the first cutoff waveguide ventilation window is guided by the air guide plate and blown onto the first heat dissipation fin. The structure is simple and accelerates the dissipation of heat on the first heat dissipation fin, thereby further increasing the heat dissipation speed of the module.

[0027] 4. In this invention, the thermally conductive limiting plate is pressed against the module under the compression of the spring, so that the thermally conductive silicone pad on the front of the thermally conductive limiting plate contacts the module, which facilitates the front and rear direction limiting of the module. At the same time, the heat of the module is transferred to the shielding plate, shielding box and heat dissipation fins more quickly, which not only realizes the portable fixation of the module, but also further accelerates the heat dissipation speed of the module.

[0043] Please see Figure 1 , Figure 2 and Figure 5 This invention provides an embodiment of a broadband electromagnetic shielding radar transmitting intermediate frequency box structure. The shielding box 1 has multiple symmetrically oriented guide grooves 12 running through its inner side. A shielding plate 13 is movably mounted inside the guide grooves 12, and a conductive rubber gasket 14 is mounted on the outer side of the shielding plate 13. A through-hole 15 is symmetrically oriented on the front of the shielding plate 13. The shielding box 1 provides installation positions for other components of the device and provides electromagnetic shielding for various modules of the radar transmitter. The guide grooves 12 guide the shielding plate 13, allowing it to move up and down within the grooves, and also provide a placement position for the shielding plate 13. The shielding plate 13 is used to shield electromagnetic waves between various modules of the radar transmitter. To prevent electromagnetic interference between modules, conductive rubber gasket 14 also provides electromagnetic shielding, preventing electromagnetic waves from passing through the gap between the bottom of shielding plate 13 and the inner wall of the bottom of shielding box 1, and also preventing electromagnetic waves from passing through the gap between the top of shielding plate 13 and the bottom of shielding cover 8. Through port 15 provides a passage for wires between modules. After wires pass through through through port 15, conductive rubber gasket is used to fill and seal it to prevent electromagnetic waves from passing through. Shielding plate 13 can move upward to detach from guide groove 12, which facilitates the disassembly, installation and maintenance of each module of the radar transmitter. At the same time, shielding plate 13 is a conductive metal, which also serves as a heat conductor, transferring the heat from each module of the radar transmitter to shielding box 1.

[0044] Please see Figure 1 , Figure 2 , Figure 6 , Figure 8 and Figure 10One embodiment of the present invention provides a broadband electromagnetic shielded radar transmitting intermediate frequency box structure. A guide plate 21 is mounted on the back of the shielding plate 13. Multiple fixed frames 27 are movably mounted on the outer side of the guide plate 21. A movable heat-conducting mechanism is provided on the back of the fixed frames 27. A bolt 38 is installed through the top of the fixed frames 27. The movable heat-conducting mechanism includes a guide rod 29, a heat-conducting rod 30, a bolt 4 31, a thermally conductive silicone pad 32, heat dissipation fins 33, and a thermally conductive silicone pad. The guide rod 29 is installed on the back of the fixed frame 27. The heat-conducting rod 20 is movably installed on the outside of the guide rod 29. Bolts 4 31 are symmetrically installed through both sides of the heat-conducting rod 20. A thermally conductive silicone pad 22 is installed at the bottom of the heat-conducting rod 20. Multiple heat dissipation fins 233 are installed at the top of the heat-conducting rod 20. A thermally conductive silicone pad 34 is installed on the back of the heat-conducting rod 20 and the heat dissipation fins 233, and the thermally conductive silicone pad 34 is in contact with the adjacent shielding plate 13 behind it.

[0045] Furthermore, the guide plate 21 can provide guidance for the fixed frame 27 and the fixed frame 25. After placing each module of the radar transmitter into the area separated by the shielding plate 13 and the shielding plate 22, the fixed frame 27 is moved left and right, thereby driving the guide rod 29 and the heat-conducting rod 30 to move left and right, so that the heat-conducting rod 30 moves to the top of the module. Then, the bolt 328 is rotated to press the guide plate 21, so that the fixed frame 27 is fixed to the outside of the guide plate 21 and will not move. Then, the heat-conducting rod 30 moves down along the guide rod 29, so that the bottom of the heat-conducting silicone pad 32 contacts the top part of each module of the radar transmitter. Then, the guide rod 29 is pressed by rotating the bolt 431, so that... The second heat-conducting rod 30 is fixed to the outside of the guide rod 29 and does not move. This allows the heat from the top of the module to be dissipated through air and through the second heat-conducting silicone pad 32 to the second heat-conducting rod 30. The second heat-conducting rod 30 then transfers the heat to the guide rod 29 and the second fixing frame 27. The heat from the guide rod 29 is also transferred to the second fixing frame 27. Then, the heat from the second fixing frame 27 is transferred to the guide plate 21. The guide plate 21 transfers the heat to the shielding plate 13 and then to the shielding box 1. The heat is then dissipated through the heat dissipation fins 4. The guide plate 21, the second fixing frame 27, the guide rod 29, and the second heat-conducting rod 30 are all made of metal and have good thermal conductivity. At the same time, the second heat-conducting rod 30 fixes the module and prevents it from moving.

[0046] Furthermore, some of the heat from the heat-conducting rod 2 30 is also transferred to the heat dissipation fin 2 33. Then, the heat dissipation fin 2 33 transfers the heat to the air inside the shielding box 1, thus dissipating the heat. The hot air inside the shielding box 1 is discharged through the cutoff waveguide ventilation window 1 3. On the other hand, the heat from the heat-conducting rod 2 30 and the heat dissipation fin 2 33 is directly transferred to the thermally conductive silicone pad 3 34. Then, the thermally conductive silicone pad 3 34 transfers the heat to the adjacent shielding plate 1 13 behind it, which is in contact with itself. Then, the shielding plate 1 13 transfers the heat to the shielding box 1, and dissipates the heat through the heat dissipation fin 1 4.

[0047] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides an embodiment of a broadband electromagnetic shielded radar transmitting intermediate frequency box structure. Multiple cutoff waveguide ventilation windows 3 are installed through the bottom of the shielding box 1. Multiple air guide plates 5 are installed at the bottom of the shielding box 1. Multiple openings 6 are symmetrically opened through the sides of the shielding box 1. Multiple heat dissipation fins 4 are installed at the bottom of the shielding box 1. A controller 2 is installed on the front of the shielding box 1. Multiple temperature sensors 7 are symmetrically installed on the inner walls of both sides of the shielding box 1, and the temperature sensors 7 are electrically connected to the controller 2. A shielding cover 8 is provided on the top of the shielding box 1. Bolts 9 are symmetrically installed through the top of the shielding cover 8, with one end of the bolts 9 penetrating through the top of the shielding box 1. Multiple cutoff waveguide ventilation windows 10 are installed through the top of the shielding cover 8. Multiple fans 11 are installed on the top of the shielding cover 8, and the fans 11 are located above the cutoff waveguide ventilation windows 10. The fans 11 are electrically connected to the controller 2.

[0048] Furthermore, when the temperature sensor 7 detects that the temperature inside the shielding box 1 has risen to the set value, the controller 2 controls the fan 11 to work. The fan 11 drives the air to quickly enter the shielding box 1 through the cutoff waveguide ventilation window 10. Then, the hot air inside the shielding box 1 is quickly discharged through the cutoff waveguide ventilation window 3, thus dissipating the heat. The air guide plate 5 is located below the cutoff waveguide ventilation window 3. The air discharged from the cutoff waveguide ventilation window 3 is guided by the air guide plate 5 and blown onto the heat dissipation fins 4, thereby accelerating the dissipation of heat on the heat dissipation fins 4. This, in turn, helps to cool down the various modules of the radar transmitter inside the shielding box 1. The bolt 9 connects the shielding box 1 and the shielding cover 8. The through-hole 6 provides a passage for the wires between the modules. After the wires pass through the through-hole 6, it is also sealed with a conductive rubber gasket to prevent electromagnetic waves from passing through.

[0049] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7An embodiment of the present invention provides a broadband electromagnetic shielded radar transmitting intermediate frequency box structure, wherein heat-conducting rings 16 are symmetrically installed on the front and back of the shielding plate 13, a spring 17 is installed on the inner wall of the back of the heat-conducting ring 16, a heat-conducting rod 18 is movably installed through the front of the heat-conducting ring 16, one end of the heat-conducting rod 18 is connected to one end of the spring 17, a heat-conducting limiting plate 19 is installed on one end of the heat-conducting rod 18, and a heat-conducting silicone pad 20 is installed on the front of the heat-conducting limiting plate 19.

[0050] Furthermore, when the various modules of the radar transmitter are placed inside the shielding box 1, the thermally conductive limiting plate 19 is pressed against the module under the elastic force of the spring 17, thereby fixing the front and rear of the module. The thermally conductive silicone pad 20 contacts the front and rear parts of the module to ensure the stability of the module. The heat of the front and rear of the module is dissipated by radiating heat to the air, and the heat of the module is transferred to the thermally conductive limiting plate 19 through the thermally conductive silicone pad 20. The thermally conductive limiting plate 19 then transfers the heat to the thermally conductive rod 18, which in turn transfers the heat to the thermally conductive ring 16, and then to the shielding plate 13. The shielding plate 13 then transfers the heat to the shielding box 1, and dissipates the heat through the heat dissipation fins 4, further increasing the heat dissipation rate inside the shielding box 1.

[0051] Please see Figure 1 , Figure 2 , Figure 6 , Figure 8 , Figure 9 and Figure 10 The present invention provides an embodiment of a broadband electromagnetic shielded radar transmitting intermediate frequency box structure, wherein a shielding plate 22 is movably installed on the outer side of the guide plate 21, and the shielding plate 22 is located between two fixed frames 27. A through opening 3 23 is provided on one side of the shielding plate 22. A conductive rubber pad 24 is installed on the outer side of the shielding plate 22. A fixed frame 25 is installed on the left side of the shielding plate 22, and the fixed frame 25 is located on the outer side of the guide plate 21. A bolt 26 is installed through the top of the fixed frame 25.

[0052] The shielding plate 22 serves to shield electromagnetic waves, preventing the electromagnetic waves generated by the modules inside the left and right side sections from interfering with each other. When a module inside the left and right side sections generates a large amount of heat, the shielding plate 22 is moved towards the module with less heat generation, thereby increasing the space occupied by the module with more heat generation and allowing the module with more heat generation to dissipate heat more quickly. The bolt 26 can compress the guide plate 21 by rotating, thereby ensuring the stability of the fixing frame 25 outside the guide plate 21. The conductive rubber gasket 24 serves to shield electromagnetic waves, preventing electromagnetic waves from passing through the gap between the shielding plate 22 and the shielding plate 13, the bottom inner wall of the shielding box 1, and the bottom of the shielding cover 8. The through-hole 23 provides a passage for the wires between the modules. After the through-hole 23 is passed through by the wires, it is also sealed with a conductive rubber gasket to prevent electromagnetic waves from passing through.

[0053] The usage method of the intermediate frequency box structure for wideband electromagnetic shielded radar transmission is as follows:

[0054] S1. Place each module of the radar transmitter into the shielding box 1 in the connection order. Each module is placed in a single section separated by shielding plate 13 and shielding plate 22. Then move the position of shielding plate 22 left and right so that the module with high heat generation occupies a large space and the module with low heat generation occupies a small space.

[0055] S2. Then, the thermally conductive limiting plate 19 is pressed against the module under the pressure of the spring 17, so that the thermally conductive silicone pad 20 on the front of the thermally conductive limiting plate 19 contacts the module, which facilitates the front and rear direction limiting of the module. At the same time, the heat of the module is transferred to the shielding plate 13 more quickly, and then to the shielding box 1, and is dissipated through the heat dissipation fins 4.

[0056] S3. Next, move the fixed frame 27 to move the heat conduction rod 30 above each module. Then move the heat conduction rod 30 down to make the heat conduction silicone pad 32 contact the top of the module, limit the top of the module, and transfer the heat from the top of the module to the guide plate 21 through the heat conduction rod 30, then to the shielding plate 13, then to the shielding box 1, and then to the heat dissipation fins 4.

[0057] S4. Then place the shielding cover 8 on top of the shielding box 1.

[0058] S4 also includes the following steps:

[0059] S41. Temperature sensor 7 detects the internal temperature of shielding box 1. When the temperature reaches the set value, controller 2 controls fan 11 to work and blow air into the shielding box 1, so that outside air enters the shielding box 1 through cutoff waveguide ventilation window 2 10, and then the hot air inside the shielding box 1 is discharged from the shielding box 1 through cutoff waveguide ventilation window 1 3.

[0060] Working Principle: Before using the broadband electromagnetic shielded radar transmitting intermediate frequency box structure, it should be checked whether there are any problems affecting its use. Place each module of the radar transmitter into the shielding box 1 according to the connection sequence. Each module is placed in a separate section divided by shielding plate 13 and shielding plate 22. Then, move the position of shielding plate 22 left and right so that modules with high heat generation occupy a larger space and modules with low heat generation occupy a smaller space. Next, the thermally conductive limiting plate 19 is pressed against the module by spring 17, so that the thermally conductive silicone pad 20 on the front of the thermally conductive limiting plate 19 contacts the module, facilitating the front-back limiting of the module. At the same time, the heat from the module is transferred more quickly to shielding plate 13, then to shielding box 1, and finally dissipated through heat dissipation. Heat dissipation fin 4 is used for heat dissipation. Then, the fixed frame 27 is moved so that the heat conduction rod 30 moves above each module. Then, the heat conduction rod 30 is moved down so that the thermal conductive silicone pad 32 contacts the top of the module, limiting the top of the module. The heat from the top of the module is transferred to the guide plate 21 through the heat conduction rod 30, then to the shielding plate 13, then to the shielding box 1, and then dissipated through the heat dissipation fin 4. Afterward, the shielding cover 8 is placed on the top of the shielding box 1. The temperature sensor 7 detects the internal temperature of the shielding box 1. When the temperature reaches the set value, the controller 2 controls the fan 11 to work and blow air into the shielding box 1. Outside air enters the shielding box 1 through the cutoff waveguide ventilation window 2 10, and then the hot air inside the shielding box 1 is discharged through the cutoff waveguide ventilation window 3.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
