Research Abstract

The micro- and nano- scale phase change phenomena and cooling technology are more important because the MEMS technology develops rapidly in the fields of electro- devices such as CPU. Therefore, the functionalized heat transfer surface is made in order to realize the enhancement of condensation heat transfer. The hybrid-condensing surface with hydrophobic and hydrophilic patterns is fabricated in order to remove the grown droplets. This is because in the dropwise condensation on the hydrophobic surface, the heat transfer coefficient is determined by the departing droplet size. In experimental results, the heat transfer coefficients on the hybrid-condensing surface show the larger value than the filmwise condensation heat transfer.
