Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and more specifically to an injection mold for a millimeter-wave radar component with high-efficiency heat dissipation. Background Technology

[0002] Millimeter-wave radar is a core component for functions such as autonomous driving and adaptive cruise control. It is often installed in confined spaces such as engine compartments and bumpers, and must withstand extreme temperatures ranging from -40℃ to 125℃. With the increasing prevalence of 77GHz long-range radar and 4D imaging radar, chip power has increased to 5-8W. Combined with the high-temperature environment of the engine compartment, the chip is prone to overheating and excessive junction temperature. For example, although the Gateland 77GHz radar chip consumes only 0.65W, it still requires auxiliary heat dissipation at high temperatures. Traditional molded components have insufficient heat dissipation capacity, leading to decreased radar detection accuracy and shortened system lifespan. Furthermore, the emergence of special components such as heated millimeter-wave cover plates places higher demands on the uniformity of heat dissipation during mold forming.
