Robust Ceramic Components for Rail Transport Equipment

Engineered technical ceramics for severe-service, always-on operation of electric and diesel rail transport equipment used for locomotives, high-speed, intercity, commuter, light rail, and people mover transit.

Electric Trains

Advanced ceramic rail components are designed for the demanding high-voltage, severe-service conditions of electric rail transport.

Diesel Trains

Diesel locomotive equipment providers use engineered ceramic components to extend useful life, improve reliability, and enhance efficiency in harsh high-temp, high-load conditions.

Alumina nitride cooling box heat exchanger for rail applications.

Case Study :: Heat Exchanger

Bombardier Transportation, formerly ABB DaimlerChrysler Rail Systems company ADtranz, partnered with CoorsTek to develop a ceramic heat exchanger for power converters used in local and metro rail vehicles. The "cooling box" heat exchanger concept that resulted supports the company's mission to answer the call for more efficient, sustainable, and enjoyable transportation by delivering:

  • Eco-friendly water cooling
    (vs. traditional oil and CFC cooling)
  • Higher efficiency cooling system
  • Longer life & lower life-cycle cost

This flat solid water-cooler has lapped surfaces and cooling plugs, arranged in form of waffles inside the box, that provide excellent heat transfer from the ceramic to the cooling water. Polyethylene water connections are inserted with two seal rings. CoorsTek engineered a high-performance aluminum nitride (AlN) heat exchanger solution which provides a combination of:

  • Strong electrical insulation — to meet demanding system requirements
  • High thermal conductivity — for efficient heat exchange
  • Corrosion resistance — enabling water cooling

These upgraded aluminum nitride-based cooling systems do a better job transporting heat from the semiconductor power electronics to the water cooling system — more efficiently, more cost-effectively, and more reliably.
