Boiling heat transfer attracts a lot of attention for cooling technology because it transports a large amount of heat with a low operating power. In particular, subcooled boiling, whose critical heat flux is higher than that of saturated boiling, is expected to be used for cooling of next-generation electronic devices. However, a subcooled liquid is easy to involve non-condensable gases that affects the bubble nucleation and boiling heat transfer. In this study, subcooled pool boiling was examined using water, considering the effect of nitrogen gas dissolved by bubbling. The experimental result found that the onset of microbubble emission boiling is affect by the nitrogen gas bubbling.
