Abstract (en)
[origin: EP1598523A1] The vane has a cooling circuit with a cooling cavity (26) delimited by a front side wall (26a) disposed on the front side (22) of the vane and a backside wall (26b) disposed on the backside (24) of the vane. One of the walls of the vane is provided with a number of dents (30) in order to hinder the flow of cooling air in the cooling cavity and to increase heat exchanges.
