Technical systems and devices are often subject to the influence of thermal energy or heat up due to internal processes. Their efficiency and service life can be increased, for example, by optimised thermal management. The installed active components are usually optimised extensively for this purpose. Passive components, on the other hand, are often neglected in this respect.
Research activities, such as those at the Institute of Thermodynamics of Leibniz University Hannover (IfT), show that there is great potential for reducing energy requirements and increasing power densities. Scientists there use infrared thermography to analyse the heat transfer to surfaces in order to increase it in the future by means of suitable measures.
