Permanent magnet air heater

摘要

A permanent magnet air heater has a housing with an internal chamber accommodating an electric motor rotating a fan to move air through the housing. A non-ferrous member having bores for cylindrical magnets and a steel member with a copper plate secured to the steel member are rotated relative to each other by the motor whereby the magnetic field between the magnets and copper plate generates heat which is transferred to air in the housing moving through the housing by the fan.

主权项

1. A heater comprising:
absorber tubing coiled around a ferrous member; a plurality of permanent magnets mounted on a non-ferrous member that is adjacent to the absorber tubing, wherein each magnet is adjacent to a magnet of opposite polarity, and wherein the non-ferrous member, including the plurality of permanent magnets, is configured to rotate relative to the ferrous member to generate a magnetic field, thereby generating heat, and wherein fluid flows through the absorber tubing and is heated as the fluid flows through the absorber tubing.
