Multidisciplinary topology optimization design of cold plate for active phased antenna array

This paper proposes a multidisciplinary topology optimization design model and method for the cold plate of active phased antenna array. Aiming at the characteristics of multidisciplinary integration of active phased antenna array, a multidisciplinary analysis model considering the thermal effect is established. Based on the multidisciplinary analysis model of antenna array, topology optimization method is used to establish a multidisciplinary optimal design model for the cold plate of antenna array. Since there is no explicit relationship between the electrical performance indicators of the antenna and the topological design variables, the adjoint method is used to derive the adjoint-governing equations that simultaneously consider fluid flow, system heat dissipation, and antenna electrical performance. The corresponding sensitivity information is obtained by solving the adjoint-governing equation. The correctness and effectiveness of the proposed model and method are verified by typical cases.
