Flow boiling technology in micro tubes has promoted the research on mechanism of critical heat flux （CHF） and its correlation properties. To improve the development and application of thermal energy conversion equipment with super-high power, we summarize the configurations of key parameters, contrast the trigger mechanisms under different mass flow rates, and review the correlation models on subcooled flow and saturated flow. The CHF enhancement effect on key parameters setting and surface status characteristics are also constrated.
