CONTACTLESS FEEDING TRANSFORMER

摘要

A contactless feeding transformer includes a double-sided winding coil with a winding (150) wound on an inter-magnetic pole core portion (143) of a core, the inter-magnetic pole core portion (143) including a plurality of separating ferrite members (243) connected to each of two magnetic pole portions (180) and disposed in parallel with a gap between each other, and heat conductors (244) disposed alternately with the separating ferrite members (243) and in contact with the separating ferrite members (243) in a plane formed by the plurality of separating ferrite members (243). The heat generated by the separating ferrite members (243) is guided outside a winding area (144) of the inter-magnetic pole core portion (143) via the heat conductors (244), and dissipated to the outside via heat conductor linking portions (245). Because the heat conductors (244) are disposed on the same plane and in parallel with the separating ferrite members (243) in such a manner as to not interlink the magnetic lines of force, the heat-dissipating characteristics of the double-sided winding coil are improved, enabling the manufacture of a small-sized contactless feeding transformer for rapid charging.
