The disclosure relates to a condensate draining device for discharging condensate from at least one cooled component, which is in particular a cooled electronic system and has a surface on which condensate formation can occur, wherein the condensate draining device has a heat conducting element which has a condensation surface and which is designed to at least partially cover the surface of the at least one component and to transfer a cold causing condensation on the surface of the at least one component to the condensation surface, further having a housing with at least one condensate drain and/or a condensate chamber for collecting a condensate forming on the condensation surface, wherein the at least one condensate drain determines in each case at least one predetermined flow path which is fluidically separated from the at least one component for draining off the condensate from the housing.

Condensate draining device, electronic assembly and method for producing a condensate draining device

The impeller has a bottom disk, a top disk, and impeller blades sandwiched between the two. The top disk has an inner opening edge that defines an axial inlet opening. The impeller blades have a first radial inward section that extends radially inward beyond the opening edge. A blade contour on each impeller blade points toward the inlet side of the impeller. The blade contour first radial inward section extends from a transition portion near the opening edge under the top disk. The blade contour on the first radially inward section of the impeller blade extends radially inward yond the opening edge and forms a specified formula geometrical edge design. A second portion of the impeller blades extends radially outward from the transition portion, the transition portion and the second portion of the impeller blade are covered entirely by the top disk from the first formula impeller blade contour.
