摘　　要：主要介绍中冷器性能测试系统的开发工作。该测试系统以水空中冷器为试验对象 ,针对传热效率和流动阻力这两项基本性能参数 ,在参照其它散热器性能评价标准和试验方法的基础上 ,应用计算机及相应的模块技术 ,实现了试验参数的实时监控、自动采集和分析处理。文中着重阐述系统方案的创建思路与实施方法 ,并结合实际运行结果 。The work of developing the test-system of intercooler′s performance will be introduced in this paper. The test specimens of the system are water-air intercoolers.On the base of the estimated standards of other intercoolers′performance and test-ways, we use the heat transfer efficiency and the air resistance as the basic performance parameters. With the applications of the computer and related data-module technology, the system can be controlled in real time, get data, analyze and deal with them automatically. This paper lays stress on the establishment thought ways , the detailed measurements ,the analysis of the existent problems and the ways to resolve them with the data we have got.
