Abstract: A heat exchanger for use in an outdoor environment with a heat pump system is provided. The heat exchanger includes a first set of tubes arranged in a parallel flow manner between a first manifold and a second manifold, wherein central straight portions of adjacent tubes are disposed with a space therebetween along each tube of the first set of tube between the first and second manifolds. A second set of tubes are arranged in a parallel flow manner between a third manifold and a fourth manifold, wherein central straight portions of adjacent tubes within the second set of tubes are at least partially disposed within the space between adjacent tubes of the first set of tubes. A fluid that flows through the first set of tubes additionally flows through the second set of tubes before the fluid returns to again flow through the first set of tubes.
