Résumé

Maldistribution in heat exchangers has a significant effect on heat exchanger performance, leading to the reduction of system performance. Maldistribution can be reduced by optimizing manifold design to evenly distribute the flow in the manifold. Recently, manufacturing of complicated distribution manifolds becomes feasible due to the development of additive manufacturing techniques which can fabricate products rapidly without using mold or tool. On the other hand, there are advantages of polymer materials, including low manufacturing cost, low weight, electrical insulators, and anticorrosion. In present work, a novel polymer distribution manifold is developed to reduce maldistribution in the heat exchanger. Then, the maldistribution reduction of the new designed heat exchangers is evaluated by a numerical model which leads to an optimal design.
