As we all know, thermal turbulence is an effective way to transfer heat through moving fluid in space. There is a boundary layer near the plate, but its heat exchange capacity is limited. In this paper, we propose a thermal vibration turbulence mechanism, which breaks through the boundary layer limitation and realizes large-scale heat transfer enhancement
