ABSTRACT:
In a parallel flow heat exchanger having an inlet manifold connected to an outlet manifold by a plurality of parallel channels, a spirally shaped insert is disposed within the refrigerant flow path in the inlet manifold such that a swirling motion is imparted to the refrigerant flow in the manifold so as to cause a more uniform distribution of refrigerant to the individual channels. Various embodiments of the spirally shaped inserts are provided, including inserts designed for the internal flow of refrigerant therethrough and/or the external flow of refrigerant thereover.
