The overall heat transfer coefficient of 15.0 wt % graphite modified polypropylene hollow fiber heat exchangers reached 1228.7 W/ (m2·K), which is 5 times higher than that of pure PP-based hollow Air-Cooled Heat Exchangers - an overview The heat capacity of gases is essential for some process engineering design, e.g., for air-cooled heat exchanger and for gas-phase chemical reactions. Here, in the latter case the heat capacities, C p 0, for gases are required to determine the heat necessary to bring the chemical compound increase to the reaction temperature.

Polymeric hollow fiber heat exchanger as an automotive

Sep 05, 2016 · Polymeric hollow fiber heat exchanger prototypes were prepared in the laboratory from polypropylene (PP) with thermal conductivity k = 0.18 W/m K by extrusion. This material is suitable to withstand operation temperatures up to 80 °C. These tiny fibers can withstand an inner pressure of 50 bar at room temperature without any damage. US4484938A - Total heat exchanger - Google PatentsA total heat exchanger for exchanging both heat and humidity is made, using partition plates of a laminate of a carbon-fiber-based paperlike material and a hydrophilic material, resulting in

Polymeric hollow fiber heat exchangers

2 Experimental details. Polymeric hollow fiber based heat exchangers (HEXs) were tested in calorimeter room of Visteon-Autopal (air velocities 110 m/s) and in calorimeter room of HeatLab (air velocities 0.22 m/s). Two pieces of HEX were tested:N1 was made of 0.6 mm fibres and N3 was made of 0.8 mm fibres.
