The present invention provides a blade or a vane component for a turbomachine. The component comprises an inner space (10) between two opposite inner walls (11, 12) of the component, a plurality of ribs (21, 22) projecting from the two opposite inner walls (11, 12) forming a plurality of channels (20) on each of the two opposite inner walls (11, 12) to guide the cooling fluid towards the trailing edge (14). The inner space (10) is divided into a leading section (30) towards the leading edge (13) of the component and a trailing section (31) towards the trailing edge (14) of the component, wherein the ribs (21, 22) are arranged in the leading section (30) and a plurality of pin-fins (26) projecting from the two opposite inner walls (11, 12) are arranged in the trailing section (31) in a discrete manner.
