    Patent number: 9022190
    Abstract: A system for transferring energy to a vehicle, in particular a track bound vehicle, such as a light rail vehicle, wherein the system includes an electric conductor arrangement adapted to produce an electromagnetic field which can be received by the vehicle thereby transferring the energy to the vehicle the system further includes electric and/or electronic devices which are adapted to operate the electric conductor arrangement. The devices produce heat while operating the conductor arrangement and—therefore—are to be cooled. A cooling arrangement of the system includes a structure having a cavity in which at least one of the devices to be cooled is located. The structure includes a cover limiting the cavity at the top, wherein the device(s) to be cooled is/are located at a distance to the cover. The structure is integrated in the ground at the path of travel of the vehicle in such a manner that the cover forms a part of the surface of the ground.
