Abstract

In this paper, we studied on the thermal design of the active antenna system for stable performance considering thermal reliability. The active antenna has high performance and heat flux elements in T/R modules. Thermal heating of elements in T/R modules has to be dissipated effectively and the antenna has to be operated over the range of suggested temperature by the thermal design. T/R modules of high heat flux in the active antenna can be dissipated effectively by liquid cooling. In this study, we studied on the thermal design including the liquid cooling system to optimize the thermal performance of the active antenna. And the thermal design was verified by numerical analysis.

본 연구는 능동형 안테나 시스템의 안정적인 임무수행을 위하여 열적 신뢰성을 고려한 방열설계에 관한 연구이다. 능동형 안테나는 송수신부에 고성능의 고발열 소자들이 존재한다. 안테나의 성능 유지를 위해서는 방열설계를 통해 고발열 소자들에서 발생하는 열을 효과적으로 제거하고, 적정한 온도범위에서 동작할 수 있도록 하여야 한다. 능동형 안테나의 송수신부는 고발열부로 액체냉각을 이용한 방열이 효과적이다. 본 연구에서는 능동형 안테나의 열적 성능을 만족하기 위하여 액체냉각 시스템을 포함한 방열설계를 수행하였으며, 이를 수치해석을 통해 분석, 검증하였다.
