Abstract
In this paper, taking a 19-unit regular hexagonal array of a certain system as an example, a scaled array antenna model is designed based on the principle that the heat flux density and the mass flow per unit area is constant. The pipe network system of the array antenna adopts the parallel design and the Tongcheng pipe network design, so that the temperature of each antenna unit remains consistent. The system simulation calculation and unit simulation calculation of the array antenna were performed by Flowmaster software and Flotherm software respectively, which verifies that the temperature uniformity of the antenna array and the temperature rise of the antenna unit meet the system requirements. At the same time, the temperature difference between the actual antenna array and the scaled antenna array is corrected by theoretical calculation. Finally, the scaled model of the array antenna is tested to verify the effectiveness of the heat dissipation design. This paper completes the research on the pipe network system of the array antenna, the flow distribution and temperature control of the antenna unit, and the temperature difference between the actual antenna and the scaled antenna, which provides technical support for the heat dissipation system of the future space power synthesis technology.
