Induction Heating – Operation, Applications and Case Studies - Presentation S...Leonardo ENERGY
The industrial process heating applications that use electrotechnologies have been found to improve product quality, productivity, energy efficiency, reduce energy intensity and have many other non-energy benefits. Induction technology is another electrotechnology based heating method for heating electrical conductive materials. It involves sending an alternating current (AC) through a copper coil which surrounds the material to be heated or melted. When a metal is placed inside the coil and enters the magnetic field, circulating eddy currents are induced within the metal. The resistance of the metal to the flow of the eddy currents causes the metal to heat up. In this webcast, the operation principles of induction heating technology used for both heating and melting, its applications and EPRI case studies will be presented. The information of vendors as well as other links to reference materials will be presented at the end.

A Thesis on Design Optimization of Heat Sink in Power ElectronicsIJERA Editor
The heat sinks are used in electronic systems to remove heat from the chip and effectively transfer it to the ambient. The heat sink geometry is designed by the mechanical engineers with the primary aim of reducing the thermal resistance of the heat sink for better cooling in the electronic systems. Due to the proximity of the heat sink with the ICs, the RF fields created by RF currents in the ICs/PCBs gets coupled to heat sinks. Hence, the coupled RF current can cause radiated emission. This radiated noise from the device can couple and disturb the functioning of the nearby electronic systems. Also this radiated emission from the device poses a problem to the system compliance with respect to EMI/EMC regulations. The international EMI/EMC standards require the radiated emission from the electronic devices to be kept below the specified limits. As a result the design of Heat Sink is very important factor for the efficient operation of the electronic equipment. In this project design optimization of a Heat sink in a Power amplifier is performed to reduce the weight and size .Power amplifier is electronic equipment mounted in an army vehicle. The power modules inside the amplifier generates a heat of 1440 Watts and a temperature of 140 0c.Two Heat sinks are used to dissipate the heat generated inside the equipment and maintain a temperature of less than 850c. The existing heat sink which is being used is weighing around 10.3kgs and height of 51mm; as a result the unit is very robust. The objective of my project is To design & optimize the heat sink to reduce the weight and size. The optimized heat sink should also dissipate heat generated by power modules and maintain a temperature of less than 850c inside. To achieve the design a steady state thermal analysis will be performed on the heat sink and plot the Temperature distribution on the fins. Based on the above analysis results we will increase/decrease the number of fins, thickness of fins, and height of fins to reduce the weight of the heat sink. We will perform CFD analysis of the power amplifier by mounting the optimized heat sink and plot temperature, pressure and velocity distribution in the power amplifier enclosure. Efforts are made to optimize temperature, pressure and velocity distribution in the power amplifier enclosure by reorienting the power modules in the enclosure. UNIGRAPHICS software is used for 3D modeling SOLID WORKS FLOW SIMULATION software is used for thermal and CFD analysis.

1. About Induction Heating
Key Benefits of Induction:
• Rapid heating
• Precise, repeatable heating
• Efficient heating
• Safe heating since there is no flame
• Extended life of fixturing due to
precise heating
What is Induction Heating?
Induction heating is a fast, efficient, precise, repeatable, non-contact
method for heating metals or other electrically-conductive materials.
An induction heating system includes an induction power supply which
converts line power to an alternating current, delivers it to a workhead
and work coil creating an electromagnetic field within the coil. The
work piece is placed in the coil where this field induces a current in the
work piece, which generates heat in the work piece. The coil, which
is water-cooled and cool to the touch, is placed around or adjacent to
the work piece. It does not touch the work piece, and the heat is only
generated by the induced current flowing in the work piece.
The material of the work piece may be a metal such as steel,
copper, aluminum or brass or it can be a semiconductor such as
carbon, graphite or silicon carbide. To heat non-conductive materials
such as plastics or glass, induction can heat an electrically-conductive
susceptor, typically graphite, which then transfers the heat to the
non-conducting material.
Induction heating is used in processes where temperatures are as low
as 100 ºC (212 °F) and as high as 3000 °C (5432 °F). It can be used in
brief heating processes that are on for less than half a second and in
heating processes that are on for months.
Induction heating is used in domestic and commercial cooking, and in
many applications such as melting, heat treating, preheating for
welding, brazing, soldering, curing, sealing, shrink fitting in industry,
and in research and development.
How does induction heating work?
It helps to start with the basics to provide a little electrical
understanding. Induction creates an electromagnetic field in a coil to
transfer energy to the work piece to be heated. When an electrical
current passes along a wire a magnetic field is created around
that wire.
2. There are Two Methods of
Heating When Using Induction:
1. Eddy current heating from the I²R
losses from the resistivity of the work
piece’s material.
2. Hysteretic heating in which energy
is generated within the part by the
alternating magnetic field created by
the coil changing the magnetic polarity of
the part. Hysteretic heating occurs in the
part up to the Curie temperature when the
material’s magnetic permeability reduces
to 1 and hysteretic heating is minimized.
The remaining induction heating effect is
by eddy current heating.
Methods of
Induction Heating
Will Induction Work for Me?
A hallmark of the Ambrell experience
is complimentary laboratory testing.
Ambrell’s applications engineers will
test your parts, determine the cor-
rect system based on your require-
ments and also determine the optimal
coil design. While we’re delighted to
teach you about induction, we’ll make
implementing induction easy.
When the electrical current changes direction (AC) the magnetic field
created collapses, and is created in the reverse direction, as the current
reverses direction. When a second wire is placed in that alternating
magnetic field an alternating current is generated in the second wire.
The current in the second wire is proportional to the current in the first
wire and to the inverse of the square of the distance between them.
When we replace the wire in this model with a coil, the alternating current
on the coil creates an electromagnetic field and while the work piece to be
heated is in the field, the work piece corresponds to the second wire and
an alternating current is generated in the work piece. Heat is generated in
the work piece due to the I²R losses of the work piece’s material resistivity.
This is called eddy current heating.
How Does an Induction Coil Work?
The work coil is used to transfer energy to the work piece using an alternating
electromagnetic field.
The alternating current flowing through the coil generates the electromagnetic
field which induces a current flowing in the work piece as a mirror image to
the current flowing in the work coil.
The work coil, also known as the inductor, is the component in the
induction heating system that defines how effectively and how efficiently
the work piece is heated.
Work coils range in complexity from a simple helical wound (or solenoid
consisting of a number of turns of copper tube wound around a mandrel)
to a coil precision-machined from solid copper and brazed together.
MAGNETIC FIELD
Induced Current in the Work Piece Current in the Coil
3. What is the Operating (resonant) Frequency?
The operating frequency for an induction heating system is dictated by the work piece
to be heated and the material it is made from. It is important to use an induction system
that delivers power over the range of frequencies appropriate for the application.
To help understand the reasons for different operating frequencies let’s look at a
characteristic known as the “skin effect.” When the electromagnetic field induces a
current in the part, it flows primarily at the surface of the part. The higher the operating
frequency the shallower the skin depth; the lower the operating frequency the deeper
the skin depth and the penetration of the heating effect.
Skin depth or penetrating depth is dependent on the operating frequency, material
properties and the temperature of the part. For example, in the table below, a 20 mm
steel bar can be stress-relieved by heating it to 540 C (1000 °F) using a 3 kHz induction
system. However, a 10 kHz system will be required to harden the same bar by heating it
to 870 °C (1600 °F).
High frequency induction heating
has a shallow skin effect which is
more efficient for small parts.
Low frequency induction heating
has a deeper skin effect which is
more efficient for larger parts.
Approximate smallest diameter for efficient heating
at different induction frequencies
Material Temperature 1 kHz 3 kHz 10 kHz 30 kHz
Steel below curie 540 °C (1000 °F) 8.89 mm
(0.35 in)
5.08 mm
(0.20 in)
2.79 mm
(0.11 in)

Steel above curie 870 °C (1600 °F) 68.58 mm
(2.7 in)
38.10 mm
(1.5 in)
21.59 mm
(0.85 in)
9.65 mm
(0.38 in)
As a rule, heating smaller parts with induction requires higher operating frequencies (often greater than 50 kHz), and larger
parts are more efficiently heated with lower operating frequencies.
With modern solid-state induction power supplies with embedded microprocessor control systems, repeatable and efficient
heating processes are readily achievable as long as every part is placed in a consistent location within the coil.
What Makes Up an Induction Heating System?
An induction heating system consists of a power supply (or inverter) a tank circuit (or workhead) and a work coil. In industrial
applications there is usually enough current flowing through the coil to require water cooling, so a typical installation includes
a water cooling system.
The power supply converts the alternating current from the AC line to an alternating current that resonates with the
combination of the capacitance in the workhead, the inductance of the coil and the resistivity of the part.
