Abstract
An induction foil cap sealer includes a sealing head module and power supply module that can be separately mounted and replaced. Both modules are convection air-cooled without a requirement for forced air-cooling or water cooling.
Claims19
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.

An induction foil cap sealer for sealing a foil cap to the opening of a container comprising:
- a sealing head module comprising:
- a coil assembly comprising:
- a magnetic flux concentrator;
- and
- an air-cooled inductor seated in the magnetic flux concentrator;
- a one or more heat pipes comprising:
- an at least one evaporator element of 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;
- and
- a power supply module comprising a power supply with an ac output, the power supply module remotely located from the sealing head module;
- and
- an at least one electrical conductor connecting the ac output to the air-cooled inductor;
- whereby the one or more heat pipes dissipate heat generated primarily in the air-cooled inductor and magnetic flux concentrator when the ac output provides a current to the air-cooled inductor, which produces a magnetic field that penetrates the magnetic flux concentrator.

An induction foil cap sealing head comprising:
- a coil assembly comprising:
- a magnetic flux concentrator comprising a ferrite core of “U” shaped ferrite segments;
- and
- an air-cooled inductor at least partially seated in the magnetic flux concentrator, the air-cooled inductor comprising an at least one Litz wire;
- 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.
