CTX at PCIM 2025

Higher performance requirements combined with miniaturisation make thermal management an increasingly important factor for long-lasting electronic components. This is especially evident in the e-mobility and energy storage sectors.

'E-Mobility and Energy Storage' will be a central focus of PCIM 2025 from 6-8 May Nuremberg, Germany. Power electronics is considered a key technology for performance in these two important areas. The role of customised cooling solutions in such applications will be demonstrated by the CTX heat sink portfolio at their company booth

In e-mobility, for instance, high-performance heat sinks from CTX provide for high-grade heat transfer. Power electronic components in charging stations and wall boxes ensure fast and safe charging of batteries in electric vehicles. This process generates high temperatures. Heat pipes quickly dissipate large quantities of such heat, and operate on the basis of a closed pipe system containing a coolant. The cooling concept allows installation virtually anywhere and is well suited for use in close spaces. Liquid-cooled heat sinks in the battery itself keep the temperature of the electronic circuitry at a balanced level. In this instance, aluminum plates with embedded copper tubes are mounted directly at the hot spot. This allows dissipation of up to 25% more heat than with fan-based cooling concepts, which makes them one of the most powerful cooling solutions.

High-performance heat sinks from CTX are also used in energy storage. Solar installations, for example, can benefit from the economical die-casting process. This forming process is used to manufacture heat sinks with complex geometries at low costs per piece, made of aluminum for a lightweight design with high thermal conductivity and good resistance to corrosion.

For inverters, meanwhile, CTX offers high-performance heat sinks with a high fin density, such as those manufactured using the skived-fin process. In this case, the very fine fins of the heat sink are pared directly from an aluminum or copper block. Since this manufacturing process eliminates the transition between the heat sink base and the fins, it facilitates cooling solutions with no thermal resistance.

A wide range of different manufacturing processes and cooling concepts allows CTX to offer one of Europe’s portfolios in this sector. Trade visitors in Nuremberg can see for themselves how the company designs cooling solutions for all areas of power electronics that are customised to the requirements of the individual application.
