From tangible basics to high-end cooling structures from the computer: Proper thermal management is crucial for the lifespan and performance of electronics. The basics by Andreas Griesinger and Tobias Best are a must for beginners and professionals in electronics development.

The Basic Day on thermal management at the Power of Electronics congress is not just a side topic but a crucial element. Originating from the former Cooling Days, we have transferred the successful concept. Anyone who wants to design electronics reliably and durably cannot bypass an efficient thermal management concept.

The Basic Day at Power of Electronics 2026 addresses exactly this and offers valuable insights for beginners and experienced professionals who want to translate theoretical content directly into practice. Two special highlights of the day demonstrate how thermal optimization works today: from the first simulation to hardware-oriented live testing.

Practical Experiments in the Morning: Theory Becomes Tangible

Prof. Andreas Griesinger from DHBW Stuttgart (Germany) will discuss a practice-oriented module on the essential basics of thermal management on September 29 at the "Power of Electronics" conference in Würzburg (Germany).(Image: Stefan Bausewein) — Prof. Andreas Griesinger from DHBW Stuttgart (Germany) will discuss a practice-oriented module on the essential basics of thermal management on September 29 at the "Power of Electronics" conference in Würzburg (Germany).

The morning kicks off with Prof. Andreas Griesinger (DHBW Stuttgart, Germany) and the lecture “Illustrative Experiments on Optimized Cooling Strategies in Electronics”. In this highly practice-oriented module, the essential fundamentals are not only discussed theoretically but demonstrated live. Participants experience firsthand how even small adjustments in hardware design can significantly reduce component temperatures. Tested are optimized design variants, geometries, surfaces, thermal interface materials (TIMs), as well as the use of heat sinks, heat pipes, and vapor chambers. A must for any developer who wants to see how design decisions play out in reality.

Detect Thermal Risks Early Thanks to Simulation

A true "veteran" is Tobias Best from Alpha Numerics. He is one of the founders of the conference, which originally started under the name Cooling Days. Today, he is an integral part of the Thermal Management track at Power of Electronics.(Image: Stefan Bausewein) — A true "veteran" is Tobias Best from Alpha Numerics.

How to systematically apply this knowledge in the development process is demonstrated by Tobias Best from Alpha Numerics in his presentation "Development-Accompanying Temperature Simulation—Developing a Thermal Management Concept Using a Practical Example". Early temperature simulation is now a key element in electronics development to avoid costly redesigns.

Tobias Best provides a deep understanding of the thermal relationships between electronic components, circuit boards, thermal bridges, and housing design, regardless of whether cooling is passive or active. What makes his seminar special is that it doesn’t stop at theory. In a collaborative case study, participants directly apply the knowledge they’ve gained to design a complete electronic device including a cooling concept. This involves both clever quick calculations and modern simulation tools.

Outlook on the Practical Day: Generative Design for Fluid Coolers

Anyone who wants to delve deeper into modern development methods after the basics should not miss the Practical Day on September 30. Here, Tobias Best follows up with a 30-minute presentation: "Development of an Efficient Fluid Cooler Based on Generative Design Software".

The development of efficient fluid coolers is highly complex. The challenge is to find the perfect balance between high heat transfer and minimal pressure loss for a given pump performance. Tobias Best presents an innovative approach where generative design methods automatically create high-performance cooling structures. Iteratively optimized through CFD simulations, this results in a holistic development approach that not only maximizes functionality and efficiency but also considers real manufacturability (Design for Manufacturing) from the very beginning.

Basic Day not Just for Beginners

The fundamentals day is explicitly not just aimed at beginners in the field of thermal management in electronics development. Experienced developers and engineers will also find valuable suggestions, current insights, and fresh approaches for their professional routine thanks to the deep expertise of the speakers and a multitude of concrete practical examples. Take advantage of the direct exchange and expand your expertise in a practice-oriented environment.
