中文摘要	传统管内冷凝器多采用无汽液分离的单一管内流程进行冷凝,会因壁面凝结逐渐增厚液膜、出现复杂两相流,冷凝换热中系统运行稳定性、流动阻力和系统的调控等严重恶化。本文通过创新的巧妙结构设计,实现沿程汽液自动分离和短管内珠状或非稳定薄液膜冷凝高效传热,开发出高性能凝结换热器。文中简要介绍了这种换热器的技术原理和思路,并给出了一些实验验证。; For a traditional condenser with tubeside vapor condensation vapor is completely condensed in one flow route without phase separation,and condensate accumulates to form thick film and complicated two phase flow which greatly decrease heat transfer coefficient and system stability and increases pressure drop.The way to enhance the performance of heat transfer is adding fins and/or inserts.Employed a very fine structure design,a kind of new high performance condenser was invented.This kind condenser would automatically separate liquid from vapor and make condensation always occur in short tubes or the entrance regions with droplet and unsteady thin film condensation mode in the whole condenser,which results in very high average heat transfer coefficient.An introduction is presented to describe the basic principle of a novel heat exchanger technology,particularly the understanding from the fundamental experimental investigations and industrial tests.
