In　this　paper,　the　frost　deposition　phenomena　on　a　cold　super-hydrophobic　surface　whose　contact　angle　with　water　is　162　degrees　were　observed　of　the　formation　of　water　droplets,　the　freezing　process　the　formation,　of　initial　frost　crystals　and　the　frost　layer　structure.　The　frost　layer　structure　formed　on　the　super-hydrophobic　surface　shows　remarkable　differences　to　that　on　a　plain　copper　surface:　the　structure　is　weaker,　looser,　thin　and　easy　to　be　removed　and　most　importantly,　it　is　of　a　very　special　pattern　a　pattern　similar,　to　a　cluster　of　chrysanthemum　petals.　a　frost　layer　structure　that　has　not　been　reported　before.　The　experimental　results　also　show　that　the　surface　has　a　strong　ability　to　restrain　frost　growth.　The　frost　deposition　on　the　surface　was　delayed　for　55　min　compared　with　the　plain　copper　surface　under　the　tested　conditions.　(c)　2008　Elsevier　Ltd.　All　rights　reserved.
