Abstract
An electromagnetic inductor and transformer device and a method for making the same are disclosed. The device has a core that is separated into core sections along a dividing plane that extends essentially parallel to the magnetic field in the core. At least one cooling gap is formed between the core sections along the dividing plane to facilitate heat removal from the interior of the inductor and transformer device to the outside.
Claims17
Electromagnetic inductor and transformer device comprising
- a core divided by at least one dividing plane and having a cooling gap disposed in said least one dividing plane, said cooling gap extending from an interior space of the inductor and transformer device to an outside region of the core, and
- at least one coil wound around at least a portion of the core and formed of a continuous conductor having a starting section and an end section, each coil having at least two planar helical winding sections, which are wound alternatingly from an inside to an outside of the interior space, and from the outside to the inside of the interior space, respectively, said at least one coil capable of producing magnetic field lines,
- wherein the at least one divining plane extends substantially parallel to the magnetic field lines.
A method for producing a coil, comprising:
- providing in a core made of a magnetic material,
- winding at least one coil around at least a portion of the core, each coil having at least two planar helical winding sections formed of a continuous conductor having a starting section and an end section, said winding sections wound alternatingly from an inside to an outside of the interior space, and from the inside to the outside of the interior space, respectively, said at least one coil capable of producing magnetic field lines, and
- providing in said core at least one dividing plane and a cooling gap disposed in said least one dividing plane, said cooling gap extending from an interior space of the inductor and transformer device to an outside region of the core, wherein an overall height of the at least one coil is obtained by adding corresponding winding heights of the at least two planar helical winding sections and a width of an insulation material disposed between the at least two planar helical winding sections.
