Abstract
The present disclosure relates to a charging apparatus for wirelessly charging a rechargeable electric energy store of a mobile terminal, having a housing, a primary coil device and a first control device operatively connected thereto, wherein the first control device is arranged in the housing, which has at least one air entry opening and at least one air exit opening. The housing further has a heat sink arranged in it that has an associated active air supply device, wherein the air supply device is set up to actively supply the heat sink with ambient air that can flow in, at least also through the at least one air entry opening. The heat sink has an associated temperature sensor device for sensing the temperature of the heat sink. The charging apparatus further has a second control device that has a signal connection to the temperature sensor device and is operatively coupled to the active air supply device, and that is set up to be able to activate the active air supply device as soon as and for as long as a predetermined first limit temperature of the heat sink has been reached or exceeded. Furthermore, the second control device also has a signal connection to the first control device and is set up to activate the active air supply device when the first limit temperature of the heat sink is reached or exceeded, and wireless charging of an electrical energy store of a mobile terminal is also performed.
