Heat Transfer on a Fluid in a Microstructure Body

Dr. Schubert, Dr. Brandner


Heat transmission to a fluid in a microstructure body involves a primary energy carrier and a secondary fluid as medium for conducting away heat liberated in the micro-heat exchanger. The energy carrier is electrical current, which within the microstructure body is converted directly into heat and then transmitted by heat conduction to the fluid to be heated. The microstructure body is formed in layers and between at least one layer with micro-channels for the fluid an electrically directly or directly heated layer is arranged. The heated layer or heating elements is/are made of Fecralloy or another metal or a metal alloy with an oxide layer on the surface for insulation.
