摘要
In order to improve the convective boiling heat transfer of R410A,the micro-fin tube was used to enhance heat transfer.The experimental studies on the horizontal micro-fin tube and smooth tube were conducted by using R410A as the working fluid.Several factors affecting heat transfer coefficients were analyzed, such as mass flux, heat flux, and quality.The circumferential wall temperature variation of the testing tubes with R410A as the working fluid was observed and analyzed.The heat transfer enhancement factor of the micro-fin tube against the smooth tube was about 1.6 to 2.2.The preliminary experiment data were useful for further research.
