Abstract
A cooled machine component having a body with at least one integrated cooling channel having a lattice structure for guiding a cooling fluid through an interior, the lattice structure arranged as a void space penetrated by a plurality of hollow or solid struts. The lattice structure has an inlet for providing the cooling fluid to be guided through the void space of the lattice structure, and has an outlet for receiving the cooling fluid, the outlet being fluidically connected to a hollow interior of at least one of the plurality of hollow struts. At least a subset of the hollow struts provides a fluidic connection for cooling fluid from the outlet to a plurality of further downstream discharge ports. Walls of the body surrounding each of the plurality of further downstream discharge ports are physically connected to corresponding jackets of the at least one of the plurality of hollow struts.
