Original Abstract

Polymeric hollow fiber heat exchangers were proposed about decade ago as an alternative to metal exchangers for low temperature application. Flexible polymeric hollow fiber heat exchangers were prepared and tested for liquid / air and liquid / liquid conditions. These heat exchangers use plastic capillary with outer diameter 0.5 – 1.3 mm and wall thickness about 10% of outer diameter. These heat exchangers are flexible and can be used in narrow slots and in shaped channels. Experimentally obtained overall heat-transfer coefficients in water/air applications are up to 900 W/m2 K. These heat exchangers are effective even in natural convection application where advantage of high heat transfer coefficient on micro surfaces is used. The use of plastic and non-corrosive materials is advantageous in applications where weight of heat exchanger is important (about 50% reduction of weight in comparison to classical metal products) and in difficult chemical environment. The paper presents results of laboratory tests of the developed prototypes of polymeric hollow fiber heat transfer surfaces for various applications.
