Abstract
An induction assembly may include a coil carrier, a coil winding, a core assembly, and a heat exchanger. The coil carrier may include an upper wall, a lower wall located opposite the upper wall, and a receiving space. The coil winding may be disposed in the receiving space. The core assembly may form a coil with the coil winding. The core assembly may include at least two core bodies that are spaced apart from one another by a gap. The heat exchanger may include an inner panel spaced apart from the core assembly and an outer wall located opposite the inner panel. The outer wall may limit a flow space through which a flow path of a cooling fluid for controlling a temperature of the induction assembly leads.

An induction assembly of an inductive charging device for inductively charging a battery in a motor vehicle, the assembly comprising:
- a coil carrier including an upper wall, a lower wall located opposite the upper wall, and a receiving space disposed between and limited by the upper wall and the lower wall;
- a coil winding received in the receiving space;
- a core assembly arranged on a side of the lower wall facing away from the upper wall, the core assembly forms a coil with the coil winding, and the core assembly includes at least two core bodies that are spaced apart from one another by a gap;
- and
- a heat exchanger for controlling a temperature of the induction assembly, the heat exchanger including (i) an inner panel which, on a side of the core assembly facing away from the lower wall, is disposed spaced apart from the core assembly and (ii) an outer wall located opposite the inner panel, the inner panel and the outer wall limiting a flow space through which a flow path of a cooling fluid for controlling the temperature of the induction assembly leads;
- wherein the coil carrier further includes a corresponding protrusion for the gap, the protrusion protruding from the lower wall and penetrating into the gap;
- and
- the inner panel includes a corresponding elevation for the gap, the elevation formed as a formation of the inner panel that is directed away from the lower wall.
