摘　　要：微通道换热器具有换热效率高、体积小、质量轻、制冷剂充注量少等优点,但是其应用于热泵型空调器室外机时存在冷凝水排水困难、制冷剂分配均匀性不佳、结霜及腐蚀等问题。本文针对这些问题,在分析现有技术的基础上,提出改进的方法和试验手段。The microchannel heat exchanger has the benefits of higher heat transfer ef-ficiency,smaller volume,lighter weight and less charge amount of refrigerant.However,when the microchannel heat exchanger is used for the outdoor unit of heat pump type air conditioner,it has the issues of drainage difficulties of condensated water,poor refrigerant distribution,frost and corrosion.For such problems,the improved methods and experi-mental measures are put forward based on the current technologies.
