Abstract |
Air cooling system is commonly employed in radar, and the distribution of cooling flow and channel design directly influence pressure drop and thermal performance. Additive Manufacturing (AM) have enhanced the ability to design complex internal cooling channels, overcoming the geometric constraints of traditional fabrication methods. In this study, the principles of Design for Additive Manufacturing were applied to develop a high-efficiency cooling plate for antenna radar. First, Computational Fluid Dynamics analysis was performed to evaluate the optimal inlet flow distribution ratio for effective thermal management of the cooling plate. Additionally, an overhang-controlled cooling channel was designed to improve manufacturability and cooling performance using DfAM, and performance factor was applied to quantitatively evaluate cooling efficiency. The results demonstrate that the proposed AM-based cooling plate offers enhanced cooling performance compared to conventional designs. |
