[0032] In the modular design of existing large-scale radar products, each module's heat dissipation structure has a separate air inlet, while the air outlets converge into a main air duct. This results in unequal air volume for each module, leading to significant differences in heat dissipation effects in different parts.

[0033] Reference Figures 1 to 4 In order to solve the above problems, an embodiment of the present utility model proposes a radar heat dissipation air duct structure, including a housing 100, a fan module 300, and an air volume equalization structure 400. Among them, the surface of the shell 100 is provided with several sub-duct inlets 200, the interior of the shell 100 is provided with a main air duct 600 connected to the sub-duct inlet 200, and one end of the shell 100 is provided with an opening; the air volume equalization structure 400 is a hollow structure, and the air volume equalization structure 400 is arranged in the main air duct 600, and an air volume buffer cavity 610 is formed between the air volume equalization structure 400 and the inner wall of the shell 100, and the air volume equalization structure 400 is provided with several through holes 401, and the interior of the air volume equalization structure 400 is connected with the air volume buffer cavity 610 through the through holes 401; the fan module 300 is arranged at the opening of the shell 100 and is connected with the outlet of the air volume equalization structure 400; wherein, the aperture of the through hole 401 located on the side of the air volume equalization structure 400 away from the fan module 300 is larger than the aperture of the through hole 401 located on the side of the air volume equalization structure 400 close to the fan module 300.

[0034] like Figures 1 to 4As shown, in this example, a plurality of sub-air duct inlets 200 are provided on the surface of the housing 100 , and each sub-air duct inlet 200 corresponds to a module of the radar, so that each module of the radar has a separate heat dissipation channel. The interior of the shell 100 is provided with a main air duct 600 connected to the sub-air duct inlet 200, and an opening is provided at one end of the shell 100. The air volume equalization structure 400 is a hollow structure. The air volume equalization structure 400 is arranged in the main air duct 600, and an air volume buffer cavity 610 is formed between the air volume equalization structure 400 and the inner wall of the shell 100. The air volume equalization structure 400 is provided with a plurality of through holes 401, and the interior of the air volume equalization structure 400 is connected to the air volume buffer cavity 610 through the through holes 401; the fan module 300 is arranged at the opening of the shell 100 and is connected to the outlet of the air volume equalization structure 400; wherein, the aperture of the through hole 401 located on the side of the air volume equalization structure 400 away from the fan module 300 is larger than the aperture of the through hole 401 located on the side of the air volume equalization structure 400 close to the fan module 300. The radar heat dissipation duct structure is generally equipped with a heat dissipation fan, which generates a heat dissipation airflow to take away the heat generated by each module of the radar, and then enters the air volume buffer cavity 610 of the main air duct 600 through the corresponding sub-duct inlet 200, and then enters the air volume equalization structure 400 and exits from the fan module 300 at the opening of the shell 100. Compared with the sub-duct inlet 200 far away from the fan module 300, the sub-duct inlet 200 close to the fan module 300 is closer to the outlet of the main air duct 600, and the heat dissipation airflow entering it will be more easily carried away. However, due to the existence of the air volume equalization structure 400, and the through hole 401 close to the fan module 300 has a smaller aperture than the through hole 401 far away from the fan module 300, the heat dissipation airflow in the air volume buffer cavity 610 enters the air volume equalization structure 400 with greater resistance. In this way, the total resistance to the heat dissipation airflow in each sub-duct inlet 200 can be basically equal, thereby achieving basically equal air volume of the heat dissipation airflow of each sub-duct inlet 200, so that the heat dissipation of each module of the radar is more uniform.

[0035] Further, refer to Figures 1 to 3 In some embodiments of the present invention, the housing 100 includes a first frame 101 and a second frame 102 connected to each other. The bottom of the first frame 101 is flush with the bottom of the second frame 102, and the height of the first frame 101 is higher than that of the second frame 102. A first chamber 601 is provided inside the first frame 101, and a first chamber 602 is provided inside the second frame 102. The first chamber 601 and the first chamber 602 are connected to form a main air duct 600. It is understood that the first frame 101 and the second frame 102 can be of other shapes as long as they facilitate the circulation of heat dissipation airflow and the installation of the radar heat dissipation duct structure itself.

[0036] Further, refer to Figure 1In some embodiments of the present invention, there are multiple sub-duct inlets 200, each corresponding to a radar module. Multiple sub-duct inlets 200 are spaced apart on the top of the second frame 102 and are all connected to the main air duct 600. Each sub-duct inlet 200 is spaced apart to provide independent heat dissipation for each radar module, avoiding heat dissipation interference caused by uneven heat generation between radar modules and ensuring more uniform heat dissipation across the radar modules.

[0037] Further, refer to Figures 3 and 4 In some embodiments of the present invention, a first baffle 501 is provided on the outer wall of the air volume equalizing structure 400 close to the fan module 300. Since the first baffle 501 separates the air volume buffer chamber 610 and the fan module 300, when the heat dissipation airflow enters the air volume buffer chamber 610 from the sub-air duct inlet 200, it can only flow to the fan module 300 through the air volume equalizing structure 400. The special design of the through hole 401 on the air volume equalizing structure 400 makes the heat dissipation of each module of the radar more uniform.

[0038] Further, refer to Figure 5 In some embodiments of the present invention, a second baffle 502 is provided on the outside of the fan module 300 for fixing the fan module 300 .

[0039] Further, refer to Figure 1 、 Figure 3 or Figure 6 In some embodiments of the present invention, the second baffle 502 is adapted to the shape of the opening of the housing 100 and is sealed to the housing 100, thereby protecting the internal structure of the radar heat dissipation duct.

[0040] Further, refer to Figure 5 In some embodiments of the present invention, the surface of the airflow balancing structure 400 is divided into multiple regions, each of which is provided with a plurality of through-holes 401. The aperture of the through-holes 401 in the region near the fan module 300 is smaller than that of the through-holes 401 in the region farther away from the fan module 300. The apertures 401 in the same region are of equal size. Since the heat generated by several radar modules in a region may be similar, the through-holes 401 in the same region are of the same size, ensuring more uniform heat dissipation across the radar modules. Furthermore, varying the aperture size of the through-holes 401 by region facilitates the industrial production of the airflow balancing structure 400.

[0041] It is understandable that the shape of the through hole 401 can be circular, square or other achievable shapes.

[0042] Further, refer to Figures 1 to 5In some embodiments of the present invention, the plurality of through holes 401 in each area are evenly arranged, so that the heat dissipation airflow evenly enters the air volume equalization structure 400 and flows to the outside through the fan module 300.

[0043] Further, refer to Figure 6 In some embodiments of the present invention, the fan module 300 includes at least one fan 301. In this embodiment, the fan module 300 includes four fans 301. The heat dissipation airflow flows to the outside through the fans 301 of the fan module 300.

[0044] Further, refer to Figure 7 In some embodiments of the present invention, the fan 301 is a turbo fan. Compared with ordinary fans, turbo fans can generate stronger wind force under the same power, thereby achieving good heat dissipation effect.
