国产印刷电路板式换热器的首次工业应用研究

印刷电路板式换热器(PCHE)具有构造紧凑、 传热效率高、 可承受高温和高压、 无管束振动、 排放容积小以及安全性高等优点,在军工舰船、 航空航天、 海洋油气开采、 石油精细化工及核工程等领域具有常规换热器难以比拟的优势.然而该设备的研制技术一直被国外公司垄断.为了推动我国PCHE的国产化进程,介绍了PCHE的结构、 ...

First Industrial Application Research on Domestic Printed Circuit Heat Exchanger

The printed circuit heat exchanger(PCHE)has the advantages of compact structure,high heat transfer efficiency,high temperature and high pressure bearing,no tube bundle vibration,small discharge volume and high safety,but the development technology of PCHE has all along been monopolized by foreign companies.In order to promote the localization process of PCHE in China,the structure,working principle and industrial application status of PCHE were introduced,the key technologies such as thermal and structural collaborative design of PCHE,photochemical etching technology of core plate,vacuum diffusion welding forming technology of core,and integrated manufacture,detection and evaluation technology of PCHE to be overcome in the development process of PCHE were analyzed,and the market prospect of PCHE in China was forecasted.China has accumulated mature technologies and experiences in the upstream(heat exchange core design and heat transfer calculation),midstream(photochemical etching and vacuum diffusion welding of plate)and integrated manufacture of PCHE,which lay a foundation for the complete localization of this technology in China.
