Description

Technical Field

[0001] This utility model relates to the field of vehicle radar heat dissipation, and in particular to an integrated heat dissipation module for vehicle radar. Background Technology

[0002] Vehicle-mounted radar is a crucial component of vehicles. It generates heat during operation, requiring a cooling module to dissipate this heat promptly for stable operation. Current vehicle-mounted radar cooling structures are modular, with each component manufactured independently, then assembled, and the joints sealed with adhesive. However, this design has several drawbacks: First, the sealant is exposed to the environment, especially under harsh conditions like high temperatures, making it prone to partial detachment or adhesion failure. This significantly increases the risk of air leakage, waterproofing failure, and dustproofing failure, resulting in low reliability. Second, the current cooling system involves numerous assembly steps, leading to low assembly efficiency and substantial increased assembly costs. Utility Model Content

[0004] According to one aspect of the present invention, an integrated heat dissipation module for vehicle radar includes: a heat sink made of a metal material with good thermal conductivity, a sealing body, and a shell made of plastic material.

[0005] The heat sink includes a flat plate body, with several heat dissipation strips integrally connected to the lower surface of the plate body and vertically connected to the four edges of the upper surface. The lower surface of the vertical wall panel is provided with an annular positioning platform and the outer peripheral wall is provided with at least one annular end platform. The lower surface of the positioning platform and the end platform is provided with an annular groove-shaped sealing opening.

[0006] The sealant body is formed by uniformly filling the sealing opening with sealant;

[0007] The outer shell is integrally connected to the wall panel and the outer surface of the sealant body through the insert molding. The middle through hole of the outer shell passes through the sheet body. The upper surface of the lower sealing ring of the outer shell is attached to the positioning platform and the sealant body, and its inner side is attached to the outer peripheral surface of the sheet body. The lower end of the vertical wall of the outer shell is attached to the outer peripheral wall of the wall panel and nested and wrapped with the end platform containing the sealant body.

[0008] In some implementations, there is one end panel, which is integrally and flush with the upper end face of the vertical wall panel.

[0009] In some implementations, the depth of the sealing opening is 0.5mm-5mm.

[0010] In some implementations, the sealant is made of silicone rubber.

[0011] In some embodiments, the lower surface of the lower sealing ring is flush with the lower surface of the plate body, and protective gaps are provided around the heat dissipation strip and the plate body.

[0012] In some implementations, a plurality of equally spaced heat dissipation strips are integrally connected to the lower surface of the chip body;

[0013] The heat dissipation strip is a rectangular prism.

[0014] In some embodiments, the outer peripheral wall of the wall panel is provided with multiple annular grooves, and the annular grooves are uniformly filled with sealant.

[0015] In some embodiments, the main body of the plate is provided with multiple screw holes, which are fixedly connected to the vehicle radar; the outer shell is provided with multiple connecting lugs with through holes.

[0016] In some embodiments, the sheet body is a rectangular block, and the positioning platform, end platform, and lower sealing ring are rectangular rings;

[0020] Alternatively, the outer casing may be made of PBT material suitable for laser welding.

[0021] This integrated heat dissipation module for vehicle radar adopts a novel structure with a one-piece injection-molded heat sink. The injection molding method uses insert molding, ensuring a tight connection between the two. Multiple sealing ports are used to inject and mold the heat sink into a sealed body, which is then tightly encapsulated within the outer shell. The advantages are: First, the integrated injection molding and multiple sealed bodies ensure a tight connection between the outer shell and the heat sink, effectively improving the product's sealing performance. This makes it suitable for harsh environments, reduces the risk of connection failure, and significantly lowers the risks of air leakage, waterproofing failure, and dustproofing failure during use, resulting in high safety and reliability.
