摘要
随着巡飞弹武器系统的发展,巡飞弹载光电载荷小型化、多功能、高集成度要求越来越高,伴随而来的散热问题也日益突出。为了解决巡飞弹载光电系统散热性能差的问题,建立了一种基于参数化建模的风冷散热系统优化设计方法。首先确定风冷散热系统的可设计参数,然后基于拉丁超立方采样方法选取多组样本点,并通过ICEPAK仿真计算得到每个样本点对应输入参数的输出响应,进而建立风冷散热器Kriging代理模型;之后基于代理模型,通过ASA(adaptive simulation annealing)自适应模拟退火算法对风冷散热器进行优化设计;最后将优化结果代入热仿真模型,验证其准确性。以某小型巡飞弹载光电系统为例,对经验设计下的风冷散热器进行热仿真分析,以热源芯片温度最小化为目标进行优化。仿真结果表明:优化后的风冷散热器相比经验设计,可使热源温升降低28.5%,有效提高了巡飞弹载光电系统的散热水平,满足系统设计要求。
With the development of the loitering missile weapon system,the requirements of miniaturization,multi-function and high integration of the optoelectronic load on the loitering missile are getting higher and higher,and the accompanying heat dissipation problem is becoming increasingly prominent.In order to solve the problem of poor heat dissipation performance of the optoelectronic system on loitering missile,an optimization design method of air-cooling system based on parametric modeling was established.The designable parameters of the air-cooling system were firstly determined,then the several groups of sample points based on the Latin hypercube sampling method were selected,and the output response of each sample point corresponding to the input parameters through ICEPAK simulation calculation was obtained,thereby establishing the air-cooling radiator Kriging proxy model.Then,based on the proxy model,the adaptive simulation annealing(ASA) algorithm was used to optimize the air-cooling system.Finally,the optimization results were substituted into the thermal simulation model to verify its accuracy.Taking a small missile-borne optoelectronic system as an example,the thermal simulation analysis of the air-cooling radiator under empirical design was carried out to optimize the temperature minimization of heat source chip.The results show that compared with the empirical design,the optimized air-cooling radiator can reduce the temperature rise of the heat source by 28.5%,which effectively improves the heat dissipation level of the missile-borne optoelectronic system,and meets the requirements of system design.
