【摘要】：随着加工技术的发展、新材料的出现,微通道换热器紧凑高效的优良性能逐渐被人们所重视,并且迅速向不同领域拓展,航空航天、暖通空调、微型核反应堆、燃料电池动力潜艇等重大设备领域中也均有涉及,但在微通道换热器的研究和应用的某些方面还存在问题,如微通道内两相流动换热的机理和流动传热计算、制冷设备中制冷剂和气流的分布、热泵系统的结霜以及制造方面的行业规范等问题,这些都限制了微通道换热器的应用推广。因此,本文围绕以上问题,对比其他类型换热器,详细介绍了微通道换热器的技术特点并对其分类,结合近些年国内外研究成果重点综述了微通道换热器的研究现状和目前主要的应用领域,从科研和应用的角度归纳了微通道换热器的应用前景和日后的研究方向,以供研究人员参考。
[Abstract]:With the development of processing technology and the emergence of new materials, the compact and efficient performance of microchannel heat exchangers has been gradually paid attention to, and rapidly expanded to different fields, aerospace, HVAC, micro nuclear reactors, However, there are still some problems in the research and application of micro-channel heat exchanger, such as the mechanism of two-phase flow heat transfer and the calculation of flow heat transfer in micro-channel. The distribution of refrigerant and airflow in refrigeration equipment, the frosting of heat pump system and the industry specification in manufacturing all restrict the application and popularization of microchannel heat exchanger. Therefore, the technical characteristics and classification of microchannel heat exchangers are introduced in detail in this paper, compared with other types of heat exchangers. Combined with the domestic and foreign research achievements in recent years, the research status and main application fields of microchannel heat exchangers are summarized. The application prospect and future research direction of microchannel heat exchangers are summarized from the point of view of scientific research and application. For the reference of researchers.
