摘　　要：首先简述了机载电子装备冷却的基本要素。其次,详细介绍了机载电子装备环控通风冷却、液体冷却方式的具体要求及不同的接口方式。然后,通过实例介绍了装备的不同冷却方式、方法及在实际中的应用。通过试验研究发现,不同的冷却方式不仅对机载电子装备本身有不同程度的影响,还对机载电子装备在环境试验过程中产生极大的影响,从而提出在实际应用中,应着重依据分析的内容考虑机载电子装备需采用的冷却方式,以达到最好的实施效果。During the use of airborne electronic equipment and environmental tests,due to the large heat generation and equipment space problems,auxiliary cooling equipment needs to be used to achieve the function of cooling.First of all,this pa-per describes the basic elements of airborne electronic equipment cooling;Secondly,this paper introduces the specific require-ments and different interface modes of environmentally controlled ventilation cooling and liquid cooling of airborne electronic equipment in detail;Then use examples to introduce the different ways and methods of equipment cooling and their application in practice of equipment cooling.Through experimental research,it was found that different cooling methods not only have dif-ferent degrees of impact on the airborne electronic equipment,but also have a great impact on the airborne electronic equipment in the process of environmental tests,so it is proposed that in practical applications,the cooling methods to be used in airborne electronic equipment should be considered according to the content of the analysis to achieve the best implementation effect.
