Based on bionics, following working rule of human sweat evaporation, the heat is dissipated by water exchange inside and out side gel. The gel contains a lot of water with normal temperature. When it comes hot, water evaporates from inside of gel, at the same time takes heat away. On the other hand, when the gel loses water, it naturally absorbs water with lower temperature from air. In this way, the heat continuously dissipates from mobilephone.
