Abstract:
An induction foil cap sealing head comprising:a coil assembly comprising: a magnetic flux concentrator; and an air-cooled inductor disposed adjacent to the magnetic flux concentrator; a one or more heat pipes comprising: an at least one evaporator element of the one or more heat pipes, the at least one evaporator element in contact with the magnetic flux concentrator; an at least one condenser element of the one or more heat pipes; and a connector for connecting each of the at least one evaporator element to each of the at least one condenser element to provide passage of a heat transfer media through the one or more heat pipes; whereby the one or more heat pipes dissipate heat generated primarily in the magnetic flux concentrator and air-cooled inductor when a current in the air-cooled inductor produces a magnetic field that penetrates the magnetic flux concentrator.
