The micro-structured heat transfer surface is a completely new developed product. Tubes, plates and more metallic profiles with nano- and microstructured surfaces cause a high boiling and heat transfer rate and can be applied in systems of cooling technology. Metallic profiles of copper, aluminium and steel can be treated by the micro-structuring technique. Depending on the physical conditions of the boiling process, the parameters of the micro-structure are adjustable. Pressure, temperature and the type of the liquid coolant determine the choice of the area density as well as height and radius of the micro-structure elements to reach the maximum vapour bubble rate and heat flux on surface.
