Stationary floor assembly for an inductive charging device

A stationary underbody assembly for an inductive charging device for inductive charging of a motor vehicle, comprising:

• a closed housing including a floor oriented transversely to a spacing direction;
• at least one flat coil arranged in the housing and disposed spaced apart from the floor in the spacing direction, the at least one flat coil including a conductor;
• a core arrangement configured to guide a magnetic flux, the core arrangement disposed in the housing spaced apart from the floor and from the at least one flat coil in the spacing direction, the core arrangement arranged between the floor and the conductor, the core arrangement including a plurality of plate-shaped core bodies oriented transversely to the spacing direction;
• a cooling air duct through which a cooling air is flowable, the cooling air duct disposed outside of the housing and extending along the floor such that an interior space of the housing and the cooling air duct are connected in a heat-transferring manner via the floor;
• and
• a plurality of supports via which the housing is supportable on a substrate, each of the plurality of supports arranged within a central region of a respective core body of the plurality of core bodies, penetrating through the floor, and projecting into the cooling air duct;
• wherein the plurality of supports connect the core arrangement and the floor in a heat-transferring manner.
