A symmetrical frame structure of antenna cabin is designed,and forced air cooling tech-nology is used to solve the cooling problem of the antenna cabin under the condition of densely dis-tributed components.The cooling air is diverted by an air duct formed between the components and the frame,achieving precise temperature control of the components and ensuring consistent surface temperature of each component.Thermal calculation and numerical simulation are conducted on the cooling system to explore a stable and reliable thermal design method with equivalent air supply for each component.The simulation and test results show that the temperature of the FPGAs of each component in the antenna cabin is consistent within±10 ℃,meeting the system requirements for equivalent air supply and achieving the purpose of heat dissipation of the antenna cabin.
