Zusammenfassung:	An intermediate device for supporting a power transfer to an electromagnetic load (505) from a power transmitter (201) providing a power transfer electromagnetic signal comprises a resonance circuit (507) that includes a coil (701) and a capacitor (703). The coil (701) is arranged to electromagnetically couple to the power transmitter (201) and to the electromagnetic load (505) such that energy of the power transfer electromagnetic signal from the power transmitter (201) is concentrated towards the electromagnetic load (505). A hollow support structure (1001) has a laterally positioned air inlet (1205) and a centrally positioned air outlet (1207). The coil (701) is mounted on the hollow support structure (1001) and disposed around the central air outlet (1207). The device further comprises an air flow generator (901) for creating a flow of air into the air inlet (1205).
