Cooling by means of polymeric hollow fibers brought BUT the Special Prize of the Committee
Millimetre polymer hollow fibres serving as cooling channels in a heat exchanger earned the Brno University of Technology the Special Prize of the Gold Medal Committee. The prize was awarded to researchers of the Faculty of Mechanical Engineering.
Miniature polymer hollow fibers can work as cooling channels of the heat exchanger. Those on display at the International Engineering Fair in Brno have an outer diameter of only one millimeter, with a wall only 0.1 millimetres thick. "Unlike any commercially available metal exchangers, the proposed design is lighter, electrically non-conductive, made of cheap materials and is generally more environmentally friendly, because the extrusion of polymeric hollow fibers produces five times less carbon dioxide than the commonly used aluminum," Jiří Hvožďa from the FSI’s Laboratory of Heat Transfer and Flow described the technology.
