Induction Heating Magnetic Iron OxideĀ in waterĀ for hyperthermia application
Objective Heating magnetic iron oxide (Fe2O3) in water for hyperthermiaĀ application to determine the curve of temperature vs. timeĀ during induction heating
Material Magnetic iron oxide in water (magnetic field is 50-200kHz,Ā 30kA/m), glass vial
Temperature Varies
Frequency 344 kHz
Equipment ā¢ DW-UHF-4.5kW induction heating system, equipped with aĀ remote workhead containing two 0.33Ī¼F capacitors for aĀ total of 0.66 Ī¼F
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A two turn helical coil is used to heat the glass vial. TheĀ temperature vs. time results are:
ā¢ 66Āŗ – 107 ĀŗF (19Āŗ – 42 ĀŗC) in 10 seconds
ā¢ 66Āŗ – 145 ĀŗF (19Āŗ – 63 ĀŗC) in 20 seconds
ā¢ 66Āŗ – 170 ĀŗF (19Āŗ – 77 ĀŗC) in 30 seconds
Results/Benefits Induction heating provides:
ā¢ Rapid & localized heating
ā¢ Uniform controllable heat
ā¢ Small bench top footprint
ā¢ Even distribution of heating
