| Based on the theory and method of water-cooled forced cooling, the thermal design of a phased array radar antenna was carried out, and liquid cooling scheme was formulated. The fluid-solid coupling thermal simulation model was built based on the CFD simulation software FloEFD. The temperature change of the key test point on the antenna was introduced by the thermal simulation for the heat dissipation of the antenna. The thermal simulation results showed that the maximum temperature of the key test points was within the allowable operating temperature range in the whole tethered test. And there was redundant time for cooling in each test period. Thermal simulation analysis indicated that the thermal design project of this device fulfilled the requirements, which also provides guidance and suggestions for the design improvement of the equipment and the optimization of the test project. |
