Abstract
An apparatus and a process are provided for impingement cooling of a component exposed to heat in a flow machine. The component includes a wall section on at least one side of which at least one impingement air flow impinges, the air flow passing through a flow channel within a surface element arranged spaced apart from the wall section and striking against the wall section to be cooled. The flow channel has an inlet aperture and an outlet aperture, with the outlet aperture directly facing toward the wall section to be cooled, and the inlet aperture has a throughflow cross section which is smaller than the throughflow cross section of the outlet aperture.
