Title:
EDDY CURRENT TYPE HEATING DEVICE
Document Type and Number:
Japanese Patent JP2017050915
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an eddy current type heating device by which kinetic energy of a rotary shaft can be effectively converted into thermal energy and recovered while suppressing a temperature rise of magnets.SOLUTION: A heating device 1 comprises a rotary shaft 3, a heating member 4, a plurality of permanent magnets 5, a magnet holding member 6, a sealed container, a nonmagnetic partition wall 15, a heat recovery mechanism and a cooling mechanism. The rotary shaft 3 is supported in a rotatable manner by a non-rotary part. The heating member 4 is fixed to the rotary shaft 3. The plurality of permanent magnets 5 oppose the heating member 4 while being spaced therefrom and between mutually neighboring permanent magnets, arrangements of magnetic poles are alternately different. The magnet holding member 6 holds the permanent magnets 5 and is fixed o the non-rotary part. The sealed container is fixed to the non-rotary part and encloses the heating member 4 and the permanent magnets 5. The nonmagnetic partition wall 15 partitions the inside of the sealed container into a first space S1 in which the heating member 4 exists and a second space S2 in which the permanent magnets 5 exist. The heat recovery mechanism recovers heat generated in the heating member 4. The cooling mechanism cools the permanent magnets 5.SELECTED DRAWING: Figure 1
