Abstract
An induction foil cap sealing system includes a ferrite core having a plurality of openings therethrough and a mounting plate with a plurality of openings therethrough which are aligned with the plurality of openings in the ferrite core. Air is directed to flow through the openings to draw heat away. A litz wire coil is disposed proximate to the ferrite core which produces an electromagnetic field within the ferrite core. The ferrite core and litz wire coil are adapted to direct the electromagnetic field toward abject to heat it.
Claims15
An induction sealing unit comprising:
- a ferrite core;
- the ferrite core having a plurality of core openings therethrough structured and arranged to allow a cooling gas to flow through the ferrite core;
- and
- a conductive coil disposed proximate to the ferrite core structured and arranged to direct an electromagnetic field towards an object to be heated.
