000022698 520__ $$2eng$$aOne type of polymeric heat exchanger is polymeric hollow fiber heat exchanger (PHFHE). PHFHEs use polymeric microchannels as the heat transfer surface. The main purpose of this work was to determine an optimal arrangement of polymeric hollow fibers inside a PHFHE shell-and-tube type. The object of study were two PHFHEs which consist of a polymeric hollow fibers with an outer diameter of 0.8 mm and inner diameter 0.65 mm. PHFHE-1 fibers were parallel to the liquid flow and in PHFHE-2 fibers were twisted by an angle of 22.5°. The heated working fluid flowed in the shell of PHFHEs and cooling water was inside the hollow fiber. Heat transfer coefficients on the outer surface of hollow fibers were obtained experimentally. It was shown that PHFHE-2 has 12.5% higher overall heat transfer coefficient comparing with PHFHE-1.
