| Abstract: | Semi-open heat pipes were studied experimentally in this work. A new kind of semi-open heat pipe with fluid swirl backflow
was developed on the basis of the traditional semi-open heat pipe. Heat transfer characteristics during operation and start-up
of closed heat pipe traditional semi-open heat pipe and swirl flow semi-open heat pipe were investigated. The swirl orifice's
backflow effect on enhancing the working limitation was obtained. Heat exchangers or waste heat boilers made of swirl flow
semi-open heat pipes and semi-open heat pipes have been successfully used in high or variable gas temperature engineering
applications. |
