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 3.000W on both sides (1.500 + 1.500), with a contact area up to a diameter of 49mm (custom tailored up to 55mm).

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.
