Embodiment Construction

[0032] figure 1 In particular from the placement of mobile terminal devices ( figure 1 (not shown in ) shows a perspective view of a charging device 10 for wirelessly charging an electrical energy storage device of a mobile terminal device. The charging device 10 can preferably be arranged in the center console of the motor vehicle, and the support area 12 can be the upper side of a housing 14 of the charging device 10 in which the charging electronics for charging the mobile terminal are provided .

[0033] Housing 14 can have at least one air inlet 16 ( figure 1 not shown in ), the air inlet can be located, for example, on the side and / or underside of the housing. Furthermore, at least one air outlet 18 can be provided, which is arranged in the mounting region 12 and is designed to blow air into the air channel 20 .

[0034] The air channel 20 can be delimited laterally by two ridges 22 extending in the length direction of the support region, the ridges being arranged pa...

Abstract

The invention relates to a charging device (10) for wirelessly charging an electrical energy store of a mobile terminal device (24) for a vehicle, the charging device (10) having charging electronics (36) and a housing (14) in which the charging electronics (36) are arranged. According to the invention, the housing (14) comprises a support region (12) for placing the mobile terminal device (24), the support region (12) having at least two elevations (22) extending in the length direction of the support region, each elevation having a first predetermined height, the elevations being arranged parallel to one another at a predetermined distance and forming an air channel (20) when the mobile terminal device (24) is placed. The housing (14) has at least one air inlet opening (16) and at least one air outlet opening (18), which is arranged in the supporting region (12) and is configured to blow air into the air channel (20). Furthermore, at least one barrier (26) is arranged in the air channel (20), the at least one barrier being configured to generate a vortex of the air blown into the air channel (20).

Description

technical field [0001] The invention relates to a charging device for wirelessly charging an electrical energy store of a mobile terminal device for a vehicle, and to a vehicle having such a charging device. Background technique [0002] Charging devices are known from the prior art for wireless charging, in particular inductive charging, of mobile communication devices or mobile terminals in general. In this case, the mobile terminal can, for example, be placed on a support surface of such a charging device, and a charge can be induced in a secondary coil located in the mobile terminal by means of an alternating magnetic field generated by the primary coil of the charging device. current and thereby charge the electrical energy store of the mobile terminal, that is to say the accumulator. [0003] During such a charging process, heat loss inevitably occurs. This heat loss leads to heating of the charging electronics of the charging device and also of the mobile terminal d...
