Embodiment Construction

[0026] exist figure 2 A laminated flux guide according to one embodiment of the invention is shown in . The laminated flux guide 10 generally includes a cover layer 15 and a thermally conductive outer layer 16 disposed on opposite sides of the arrangement of alternating layers of high magnetic permeability material 12a-d and electrically insulating material 14a-c. The number of alternating layers can vary. The cover layer 15 may be a thin layer of material capable of holding the laminated flux guide together and providing a vapor barrier protecting the underlying high permeability material layer. The thermally conductive layer 16 can be a metal or metal that can also hold the laminated flux guide together and provide a vapor barrier that protects the overlying layer of high permeability material, as well as provide a heat flow path for removing thermal energy from the flux guide. Thin layers of other thermally conductive materials. For example, the thermally conductive laye...

Abstract

The invention relates to a magnetic flux guide component. A laminated flux guide with a cover layer and a thermally conductive layer disposed on opposite sides of a plurality of alternating layers of high permeability and electrically insulating materials is provided. The thermally conductive layer may be a metal, such as aluminum. The present invention also provides a method of manufacturing including the general steps of: providing a plurality of rolls of high permeability material; providing a roll of thermally conductive material, providing a roll of cover material; applying an electrically insulating adhesive between adjacent layers of the high permeability material; feeding the high permeability material layers with the applied adhesive into pressure rollers to form a pre-laminate; feeding the thermally conductive layer, the pre-laminate and the cover layer into pressure rollers to join them under pressure into a final laminate and cutting the final laminate into the desired shape.

Description

technical field [0001] The present invention relates to magnetic flux guides and methods of making magnetic flux guides. Background technique [0002] Magnetic flux guides (sometimes referred to as flux concentrators, flux focusers, flux enhancers, flux splitters, flux controllers, flux reflectors, and other names) are generally known as And has been used to control the flow of magnetic fields in applications such as induction heating and inductive power transfer applications. A flux guide typically helps control the flow of the magnetic field by providing a high permeability flow path. By providing a high permeability flow path, flux directors provide a path of least resistance while effectively attracting more magnetic fields. This enhances the magnetic field in a specific area and can help improve power efficiency. In the absence of a flux director, the magnetic field is more likely to spread out and intersect with any conductive surroundings. In some cases, a flux sh...
