Dimensionamento de sistema de resfriamento por água de fios poliméricos flexíveis processados por extrusão

Abstract

With the need for a cooling system for the extruded filament in a laboratory extruder, the possibility of designing a cooling system is inferred. This system, by submerging the extruded filament, facilitates heat exchange and promotes the solidification of the polymer. When studying the properties of polymers, the need for temperature control of the water and the immersion time of the filament are process parameters that directly affect the quality of the extruded filament. To control these parameters, the filament's passage velocity was calculated, considering natural convection and transient heat conduction, based on the fluid temperature and the bath dimensions. Given the challenge of water temperature increase, it was necessary to design a heat exchanger to ensure stable temperature conditions within the system. With the obtained results, a 3D CAD model of the entire system was developed, along with the selection of components and the technical drawings of the system's parts.
