Abstract (en)
The invention relates to a coolable wall element (10) for gas turbines for a hot gas environment, comprising a first surface (12) subjectable to a hot gas and a second surface (14) subjectable to a cooling fluid (17), the first and second surface (12, 14) are arranged opposite to each other, where in the second surface (14) comprises at least one turbulence enhancing element (16) which projects steplike from the second surface (14) to a free ending top (18) of the turbulence enhancing element (16), the top (18) comprises a top surface (20). To provide a coolable wall element (10) with enhanced cooling properties and fewer blockages inside of a cooling cannel, it is proposed that the top surface (20) comprises a depression (22).
