    Product Detail

    Induction Heating Capacitors

    The induction heating machine contains three main components: working coil, the power supply and tank circuit. The induction coil generates the electromagnetic field which produce the heat, the power supply converts the line signal to alternating current and deliver it to the smelting work, and the tank circuit generated the operating frequency. Flair designed water-cooled plastic film capacitors are suitable for the induction heating equipment.
    The suitable capacitors are developed in order to minimize internal losses thus it can work in electric circuits with high frequencies, by very high current and high working voltage. Fluid cooling capacitors can achieve quite high working rated power, in a range from hundreds of kVA to few MVA.
    The internal losses are the reason for the rise of the heat which have to be removed. This heat could cause the destruction of the capacitor if the heat removal is not sufficient. A permissible temperature rise of the capacitor effected by the power dissipation also depends on the ambient temperature that needs to be considered during design-in.
    By using water-cooled capacitor is useful to make energetic balance with a appropriate cooling of the capacitor.
    With development of induction heating furnace technology, as well as promoting the induction heating electronics progress. The induction heating/melting plants demand higher requirements on electrical components for power conversion, especially to the inductor and capacitor components.
    To be a capacitor manufacturer, flair is putting a persistent efforts on capacitors development for increasing power density for electrical switching power converters.
    Considering the various demanding of the induction heating capacitors, apart from the traditional water cooled capacitors, air cooled capacitor is also demanding, of which dry type induction heating capacitors is developed and gradually used by some customers. The water cooled induction heating capacitor are oil-impregnated with water tubes layout. The traditional furnace design is using water cooled type capacitor which must be applied for maybe hundreds of cooling water tubes for heat dissipation.
    The cooling water tubes are deployed as the the following chart.

    Frequently Asked Questions

    Q: What are the three main components of an induction heating machine?
    The induction heating machine contains three main components: the working coil (which generates the electromagnetic field producing the heat), the power supply (which converts the line signal to alternating current for the smelting work), and the tank circuit (which generates the operating frequency).
    Q: Why are water-cooled plastic film capacitors preferred for high-frequency induction heating?
    These capacitors are specifically developed to minimize internal losses. This allows them to work efficiently in electric circuits characterized by high frequencies, very high currents, and high working voltages.
    Q: What rated power range can fluid-cooled capacitors support?
    Fluid-cooled (water-cooled) induction heating capacitors can achieve a very high working rated power, typically ranging from hundreds of kVA to a few MVA.
    Q: How does heat dissipation affect the lifespan of these capacitors?
    Internal losses cause a rise in heat. If the heat removal is not sufficient, it can lead to the destruction of the capacitor. The permissible temperature rise depends on both power dissipation and the ambient temperature, which must be accounted for during system design.
    Q: What is the difference between traditional water-cooled and dry-type air-cooled capacitors?
    Traditional water-cooled capacitors are oil-impregnated and deploy water tubes (sometimes hundreds of them) for heat dissipation. Conversely, dry-type air-cooled capacitors are designed to meet modern requirements for increasing power density without relying on complex water cooling layouts.
