Construction element for use in a thermal machine

摘要

The thermic machine component (9) has a wall element (10) with an internal cooling region (11) having a cooling surface (12) supplied with a cooling medium and an external surface (13) which lies in contact with the hot medium (M) during operation of the thermic machine. The cooling medium feed line (16) passes through an edge (14) between the inner cooling region and an outer edge surface (15) at an angle to the external surface in contact with the hot medium.
