Simulation and numerical computation of three-dimensional air flow and heat transfer in car radar chamber were carried out using computational fluid dynamics and heat transfer method. Three-dimensional physical model and mathematical model for air flow and heat transfer calculation was established. Three-dimensional simulation and numerical computation of air flow field and temperature field in certain car radar chamber was carried out using the turbulence model equations, unstructured grids and finite volume method. The purpose was to provide theoretical basis and technical guidance to improve the living environment of automotive radar.
