Abstract
A device for wireless transmission of electrical energy to an energy receiver, including a support surface, on which the energy receiver is arranged during energy transmission. The device includes an induction coil for transmitting electrical energy and an air duct extending within the device from an opening formed in the support surface into the device. The opening is arranged over the induction coil. The air duct is routed through a winding of the induction coil, which is preferably arranged directly under the support surface. Advantageously, the support surface is essentially rectangular, and the opening is formed on or at least close to a longitudinal axis of the support surface and is formed at a distance from an edge of the support surface. At least one projection is formed on the support surface for holding the receiving unit at a distance from the support surface so that air conducted into the air duct can better flow underneath.
