Polymeric hollow fiber heat exchangers (PHFHE) are heat exchangers which use polymeric microchannels as the heat transfer surface. The main purpose of this work was to determine an optimal arrangement of polymeric hollow fibers in a PHFHE. The object of study was a bundle of parallel polymeric hollow fibers with an outer diameter of 0.8 mm. The heated working fluid flows inside the hollow fiber. Heat is transferred by a cooling medium from outside of the hollow fibers. Heat transfer coefficients on the outer surface of hollow fibers were obtained using computer modelling. For the case of water cooling a sharp heat transfer coefficient increase was observed as the angle between the hollow fiber position and the direction of the cooling medium flow α increases to 30°, its further increase to 45° had no significant effect. With water cooling, total heat transfer coefficient of PHFHE increased by 35%, at the air cooling - by 15%. Angle 30° can be considered as an optimal for manufacturing of such PHFHE.
