舰载雷达发射机柜热状态仿真分析

Simulation analysis on the thermal status of the transmitter cabinet of a shipborne radar

针对雷达发射机柜工作时温度过高会降低电子元器件寿命这一状况,本文简化机柜模型,建立有限元模型,运用ESC软件分析两种不同通风条件下机柜内部热状态,并对结果进行比较,为机柜通风装置设计提供理论依据。

In consideration of the fact that high temperature may shorten the life-span of electronic components while the transmitter cabinet of a shipborne radar is working, the cabinet model is simplified, and the finite element model is established. The analysis through the software ESC is made on the heat status inside the cabinet under different conditions of ventilation. The results provide theoretical basis for the design of ventilation apparatus for transmitter cabinet.
