An inductor which avoids heat generation and heat dissipation problems, and has a reduced resistance component, when used in a voltage converter. An inductor is configured with a pair of outer electrodes disposed on both end portions of an element assembly and electrically connected to end portions of conductors. The conductors are made of a flat-type wire having a rectangular cross section, are placed side by side between the end portions, and include cylindrical winding sections, respectively, in which the flat-type wire in a long side direction of the rectangular cross section is wound the number of turns less than one about a thickness direction intersecting with a length direction connecting the pair of end portions along the thickness direction. A heat-dissipating member includes a portion being a partition between the conductors and a portion exposed on the top of an outer surface of the element assembly.

A reactor is equipped with a coil having unit coils. First spacers are disposed in at least one of spaces between the unit coils and in a space between one of the unit coils and a supporting frame. Second spacers are disposed between the first spacers. The supporting frames, the first spacers, and the second spacers are traversed by bolts and are fixed to the bolts. A space is defined between the bolt and a wall surface of a through hole formed in the first spacer and traversed by the bolt. A spacing distance between adjacent first spacers in the central axis direction of the coil is greater than a central-axis-direction thickness of the unit coil located between the adjacent first spacers, the central-axis-direction thickness of the unit coil being of when the coil is not energized.

A transformer station, in particular, an offshore transformer station including at least one transformer and at least one transformer cooling unit arranged on at least one side wall of the transformer station or a roof of the transformer station and configured to cool the at least one transformer. The transformer station also includes at least one air deflecting unit arranged on at least one roof edge of the transformer station and/or at least one air deflecting unit arranged on at least one side edge of the transformer station. The air deflecting unit is arranged such that an air movement is deflectable in the direction of the transformer cooling unit.

A wireless device charger is configured to produce an alternating magnetic field, thereby inducing an alternating electrical current within a capture coil of a personal electronic device proximate to the wireless device charger. The wireless device charger includes a source coil having a ferrite element configured to generate the alternating magnetic field, a housing formed of a thermally conductive material in thermal communication with the ferrite element, and an air movement device configured to produce a turbulent air flow across a surface of the housing flowing from an air inlet to an air outlet, thereby reducing a housing temperature.

A transformer includes: a base that is a plate-like member and has a first surface and a second surface, a core attached to the first surface of the base, coils wound around the core, coil terminals attached to the second surface of the base, and a cooling unit that is thermally connected to the core and is to release heat transferred from the core. The coil terminals are disposed on the second surface of the base opposite to the first surface of the base to which the core is attached. The cooling unit is disposed on a side of the core opposite to the base.

A self-cooled reactor apparatus includes: a pair of frames attached to a vehicular mount, a coil disposed between the pair of frames and fixed to the frames, a cover disposed between the pair of frames, and a protective member. The coil is covered by the cover having at least a portion thereof in which through-holes are formed. The protective member, while retaining a flow passage for air from the through-holes to the coil, blocks a space between the through-hole and the coil in a penetration direction of the through-holes.

An example inductor comprises multiple coil parts and each formed by flatwise-winding layers of turns of a flat wire arranged in a radial direction with gaps between each of the layers, and the multiple coil parts are arranged in an axial direction with a clearance. There is provided a clearance between the multiple coil parts, through which air flows, achieving improvement in heat dissipation.
