摘要：

The　effect　of　cold　plate　temperature　on　water　droplet　freezing　process　on　hydrophobic　surface　was　investigated;　the　water　droplet　freezing　time　and　freezing　shape　were　compared.　The　experimental　results　showed　the　water　droplet　freezing　time　decreases　with　the　decreasing　of　cold　plate　temperature.　The　lower　the　cold　plate　temperature　is,　the　stronger　the　dendritic　frost　crystals　grow　on　the　frozen　water　droplet　surface.　A　mathematic　model　for　the　water　droplet　freezing　time　was　proposed　based　on　energy　conversation,　the　effect　of　cold　plate　temperature　on　water　droplet　freezing　was　analysed,　and　the　prediction　results　of　the　model　is　in　general　agreement　the　experimental　results.
