WATER COOLER BAE9 During the
course of recent years the development of electronic power components has made necessary
to dissipate larger quantities of thermal heat at lower values of junction temperatures in
order to increase their operating life.
The designers have become more and more familiar with alternative
cooling systems, such as water cooling, that have shown the highest reliability in severe
environmental conditions.
As an answer to high power dissipation problems, BTM has designed and
developed a new family of aluminum water coolers, suitable to accept Thyristors, GTOs, and
the recent IGBT components, dissipating up to 4.000W on both sides (2.000 + 2.000), with a
contact area up to a diameter of 79mm (custom tailored up to 85mm).
This new cooler family can be easily adapted to the customer needs, by
mounting the proper cooling fluid nipple (aluminum, titanium, etc.).

The basical concept of
these coolers makes them really cost-effective, allowing a longer operating life to the
components at a really reasonable price, this permitting to adopt them in the most part of
heavy industrial applications, welding, light and heavy electrical traction.
