Power Assembly Complete Solutions
Heatsinks, Clamps and Sub-contract Partnership
Heatsinks
Dynex has its own
proprietary range of
extruded aluminium
heatsinks designed to
optimise the performance
of our semiconductors. We
also have access to a vast
range of aluminium
extrusions from
independent manufacturers
giving our design team the
best options available.
Device Clamps
A line of pre-loaded clamps
is offered, from cube
clamps for single side
cooling up to 30mm discs
and bar clamps up to 83kN
for our 100mm disc
devices. Bar clamps are
suitable for single and
double side cooling, with
high insulation versions
available for high voltage
assemblies.
Clamps can also be
supplied separately as a kit
of parts.
Sub-Contract
Partnership
Our experienced engineers
and assemblers have
worked closely with
customers throughout the
world to manufacture
assemblies to their
requirements. Typically
this work has included
marine propulsion, rail
traction and power utility
Air cooled and water cooled (cooler) heatsinks for simple and
complex assembly designs
Bar and cube clamps are availabe to fit all Dynex bipolar prod-
ucts. Bar clamps are suitable for single or double side cooling
arrangements
Water cooled heatsinks
(coolers) are available and
are compatible with
devices up to 100mm
silicon diameter. They are
designed for use in high
current, high power
assemblies such as single,
three or six phase bridges
or A.C. controllers.
Complete bridges of up to
six devices may be
constructed and two
coolers per device may be
used for double side
cooling.
applications. The PACS
group has encouraged the
philosophy of joint design
and build to customer’s
specifications.
In addition to new design
and build work Dynex also
untake refurbishment of
assemblies. This process
involves the stripping down
on an existing assembly
into its component parts
and cleaning, replacing,
rebuilding and testing the
assembly before it is
handed back to the
customer. This service has
proved especially
beneficial to railway
traction operating
companies who do not
have the facilites or the
skilled engineering staff to
undertake this type of
work.

ready to discuss
‘partnership’ projects with
