<p>A receiving device 1 for inductive power transfer to a vehicle comprises a housing 4, wherein a medium is contained in the housing 4 that has thermal coefficient of expansion smaller than that of air. The medium or filler may be or comprise oil, and it may have a coefficient of thermal conductivity higher than that of air. Part of the receiving device may be embedded in the medium so that the medium conducts heat from the receiving device element to surrounding environment. The medium may be contained in a chamber 11, 12, 13 within the housing 4, and the walls of the chambers or cavities 11, 12, 13 may be non-magnetic and may be oil proof, preventing the leakage of oil. Damage to the housing 4 due to thermal expansion of air is thereby avoided.</p> |
