Zusammenfassung:A platform cooling device (10) for directing a cooling fluid onto a root side (52) of a platform (50) of a turbomachine part (2) is presented. The platform cooling device (10) includes a first segment (20) to be positioned at a root (60) of the turbomachine part (2) and a second segment (30), at an angle to the first segment (20), to be positioned at the root side (52) of the platform (50) of the turbomachine part (2). The second segment (30 includes at least one impingement channel (32) having an inlet (34) for receiving at least a part of the cooling fluid and an outlet (36) for releasing the received cooling fluid onto the root side (52) of the platform (50). The first segment (20) and the second segment (30) define a path for the cooling fluid via the impingement channel (32). A turbomachine component (1) including the platform cooling device (10) is also presented.
