Description

Technical Field

[0001] The utility model relates to the technical field of radar heat dissipation, in particular to a heat dissipation structure for a radar antenna. Background Technique

[0002] The radar antenna is a crucial component in the radar system. It is a device in the radar that radiates and receives electromagnetic waves and determines its detection direction. It focuses the electromagnetic waves into a beam to achieve directional transmission and reception, thereby measuring information such as the position, speed, and altitude of the target object.

[0003] Currently, a large amount of heat is generated when the radar antenna is working. If the heat cannot be dissipated in time, it may cause the internal temperature of the antenna to be too high, and then damage the antenna components, such as the chips in the T / R component (including functional circuits such as low-noise amplifiers, high-power amplifiers, phase shifters, and T / R switches). Through effective heat dissipation design, it can ensure that the antenna components operate within the normal working temperature range and avoid damage caused by overheating. However, the existing method of dissipating heat from the radar antenna by a fan has a slow heat dissipation efficiency and cannot change the ambient temperature around the radar antenna, resulting in poor heat dissipation effect.

[0004] Therefore, in view of the above problems, it is necessary for the applicant to design a heat dissipation structure for a radar antenna to solve the problems. Summary of the Invention

[0005] The purpose of the utility model is to provide a heat dissipation structure for a radar antenna to solve the problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A heat dissipation structure for a radar antenna, including a base, and a support seat is fixedly arranged on the top surface of the base. A support frame is arranged on the top surface of the support seat, and a radar antenna is detachably installed on one side of the support frame.

[0007] It further includes,

[0008] A heat dissipation mechanism arranged on one side of the radar antenna. The heat dissipation mechanism includes a fixed seat fixedly connected to the base. A fan is fixedly arranged on the top surface of the fixed seat. The output end of the fan is fixedly connected to a connecting pipe, and one end of the connecting pipe far away from the fan is fixedly connected to an air intake component for sucking air. The air intake component includes a connecting plate fixedly connected to the connecting pipe. A hollow sleeve is fixedly arranged on one side of the connecting plate, and an air suction cylinder is detachably installed inside the hollow sleeve.

[0009] Further, an installation ring is fixedly arranged on the side of the air suction cylinder close to the radar antenna, and a filter screen is arranged inside the installation ring.

[0010] With the above structural design, the filter screen facilitates preventing sundries in the air from entering the air distribution fan through the connecting pipe, which is conducive to improving the safety of the fan and extending its service life.

[0011] Furthermore, a support plate is fixedly arranged on the outer side of the connecting plate. A column is fixedly arranged on one side of the support plate, and the end of the column far away from the support plate is fixedly connected to the base.

[0012] With the above structural design, the column facilitates stably supporting the support plate, and the support plate facilitates stably supporting the connecting plate, thereby enabling the air intake assembly to suck air stably.

[0013] Furthermore, a reinforcing screw is detachably installed on the outer side of the column, and one end of the reinforcing screw penetrates through the support plate and extends into the interior of the support plate.

[0014] With the above structural design, the reinforcing screw facilitates improving the connection stability between the column and the support plate.

[0015] Furthermore, a threaded groove is formed inside the hollow sleeve, and a threaded strip is fixedly arranged on the outer side of the air suction cylinder, and the threaded strip is adapted to the threaded groove.

[0016] With the above structural design, by using the threaded groove and the threaded strip, the hollow sleeve and the air suction cylinder can be conveniently disassembled or installed, thereby facilitating the replacement of the filter screen.

[0017] Furthermore, a groove is formed near the center of the support plate, and a mounting frame is fixedly arranged inside the groove, and a fan is detachably installed inside the mounting frame.

[0018] With the above structural design, the fan facilitates heat dissipation, and the fan can accelerate the air flow, which is conducive to the outside cold air filling the space where the hot air sucked away by the fan is, thereby improving the heat dissipation efficiency.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: This radar antenna heat dissipation structure facilitates dissipating heat from the radar antenna, and has high heat dissipation efficiency and good heat dissipation effect. The specific content is as follows:

[0020] 1. A heat dissipation mechanism is provided. When in use, when the radar antenna needs to dissipate heat, the fan and the blower are started. The blower will suck the hot air flow in the air and discharge it to a position far away from the radar antenna. The extraction of the hot air will cause the outside cold air to enter the periphery of the radar antenna, which is conducive to heat dissipation. At the same time, the fan will accelerate the air flow, which is conducive to accelerating the filling of the outside cold air into the space where the hot air sucked away by the blower is, thereby improving the heat dissipation efficiency and having a good heat dissipation effect.

[0021] 2. A filter screen is provided. During use, after the fan has been in operation for a period of time, dust and other debris will accumulate on the outer side of the filter screen, which will reduce the operating efficiency of the fan. At this time, by applying an external force to rotate the mounting ring, the mounting ring will drive the air suction cylinder to rotate. The rotation of the air suction cylinder facilitates its detachment from the hollow sleeve, making it easy to replace the filter screen. The operation is convenient and the replacement efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1-4As shown in the figure, a heat dissipation structure for a radar antenna of the present utility model includes a base 1, and a support base 10 is fixedly arranged on the top surface of the base 1. A support frame 11 is arranged on the top surface of the support base 10, and a radar antenna 12 is detachably installed on one side of the support frame 11. It also includes a heat dissipation mechanism 2 arranged on one side of the radar antenna 12. The heat dissipation mechanism 2 includes a fixed seat 26 fixedly connected to the base 1. A fan 20 is fixedly arranged on the top surface of the fixed seat 26. The fan 20 is an existing air suction device. An air suction device is a device that drives the impeller to rotate at a high speed through an electric motor, sucks in gas, pressurizes it and then transports it. The output end of the fan 20 is fixedly connected to a connecting pipe 21, and one end of the connecting pipe 21 far away from the fan 20 is fixedly connected to an air inlet assembly 22 for sucking air. The air inlet assembly 22 includes a connecting plate 220 fixedly connected to the connecting pipe 21. A hollow sleeve 221 is fixedly arranged on one side of the connecting plate 220, and an air suction cylinder 222 is detachably installed inside the hollow sleeve 221. A support plate 23 is fixedly arranged on the outer side of the connecting plate 220. A column 24 is fixedly arranged on one side of the support plate 23, and one end of the column 24 far away from the support plate 23 is fixedly connected to the base 1. A reinforcing screw 240 is detachably installed on the outer side of the column 24, and one end of the reinforcing screw 240 penetrates through the support plate 23 and extends into the interior of the support plate 23. A groove is opened near the center of the support plate 23, and a mounting bracket 25 is fixedly arranged inside the groove, and a fan 250 is detachably installed inside the mounting bracket 25.

[0029] Through the above structural design, during use, when the radar antenna 12 needs to dissipate heat, the fan 20 and the fan 250 are started. The fan 20 will suck in the hot air flow in the air and discharge it to a position far away from the radar antenna 12. The extraction of the hot air will cause the cold air from the outside to enter the periphery of the radar antenna 12, facilitating heat dissipation. At the same time, the fan 250 will accelerate the air flow, facilitating the acceleration of the cold air from the outside to fill the space where the hot air sucked away by the fan 20 is located, improving the heat dissipation efficiency and having a good heat dissipation effect.

[0030] An installation ring 223 is fixedly arranged on one side of the air suction cylinder 222 close to the radar antenna 12, and a filter screen 224 is arranged inside the installation ring 223. The hole size of the filter screen 224 is determined according to the actual situation. A threaded groove 225 is opened inside the hollow sleeve 221. A threaded strip 226 is fixedly arranged on the outer side of the air suction cylinder 222, and the threaded strip 226 is adapted to the threaded groove 225.

[0031] Through the above structural design, during use, after the fan 20 has been used for a period of time, dust and other sundries will accumulate on the outer side of the filter screen 224, which will reduce the use effect of the fan 20. At this time, the installation ring 223 is rotated by an external force, and the installation ring 223 will drive the air suction cylinder 222 to rotate. The rotation of the air suction cylinder 222 facilitates its detachment from the hollow sleeve 221, facilitating the replacement of the filter screen 224. The operation is convenient and the replacement efficiency is high.

[0032] Working principle: When using this radar antenna heat dissipation structure, when the radar antenna 12 needs to dissipate heat, the fan 20 and the fan 250 are started. The fan 20 will suck in the hot air flow in the air and discharge it to a position far away from the radar antenna 12. The extraction of the hot air will cause the cold air from the outside to enter the periphery of the radar antenna 12, facilitating heat dissipation. At the same time, the fan 250 will accelerate the air flow, facilitating the acceleration of the outside cold air to fill the space where the hot air sucked away by the fan 20 is, improving the heat dissipation efficiency and having a good heat dissipation effect. After the fan 20 is used for a period of time, dust and other sundries will accumulate on the outer side of the filter net 224, which will reduce the use effect of the fan 20. At this time, the mounting ring 223 is rotated by an external force, and the mounting ring 223 will drive the air suction cylinder 222 to rotate. The rotation of the air suction cylinder 222 facilitates the separation from the hollow sleeve 221, which will facilitate the replacement of the filter net 224, with convenient operation and high replacement efficiency.
