摘要
A parallel tube heat exchanger receiving two-phase refrigerant flow from a common manifold is provided with an eductor nozzle in one end of the manifold so as to cause the flow of refrigerant to pass along one leg of the manifold and down another leg thereof so as to reenter the upstream end of the first leg by way of a crossover tube. In this way, the two-phase refrigerant flow to the parallel tubes is more uniformly distributed. In one embodiment of the invention, the manifold is a unitary tube with a centrally disposed, longitudinally extending partition to define two longitudinally extending chambers that fluidly communicate by gaps at the ends of the central partition.
