摘要: 探测器阵列靶是测量激光光斑分布的常用设备, 在高功率激光长时间辐照下阵列靶的取样面板需要更高的 抗损伤能力。为了提高取样面板的抗损伤能力, 从热设计角度出发, 基于Ansys Workbench有限元分析软件, 比较 了不同厚度、不同热管排布方式以及不同界面传热系数下, 防护取样面板在高功率激光长时间辐照下的温度场和热 应力。分析结果表明, 添加十字热管排布后, 在激光辐照 120 s 时, 6 mm 厚度的取样面板耐受峰值功率密度从 1470.9 W·cm-2 提高至3632.1 W·cm-2 。该仿真分析为阵列靶防护取样面板的设计提供了有效的理论和数据支持。

Abstract: Detector array target is a common device for measuring the distribution of laser spot, and the sampling panel of array target needs higher damage resistance under long-term high-power laser irradiation. In order to improve the damage resistance of the sampling panel, based on the finite element analysis software Ansys Workbench, from the perspective of thermal design, the research compares the temperature field and thermal stress of the protective sampling panels with different thicknesses, different heat pipe arrangements and different interface heat transfer coefficients under long-term high-power laser irradiation. The analysis results show that after adding a cross heat pipe arrangement, the withstand peak power density of the sampling panel with a thickness of 6 mm increases from 1470.9 W·cm-2 to 3632.1 W· cm-2 when the laser irradiation lasts for 120 s. This simulation analysis provides effective theoretical and data support for the design of protective sampling panel for array target.
