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.

Dual heat exchanger for heat pump system

A heat exchanger () for thermally coupling a first fluid to a second fluid so as to transfer heat and in a fluidically separate manner includes a securing assembly () of two cover parts () and at least one, preferably a plurality of guide parts (), through which duct tubes () of the heat exchanger () pass. The duct tubes () extend inside a housing tube () along the longitudinal axis of the housing tube (). The first fluid passes through the housing tube () outside of the duct tubes (), and the second fluid passes through the duct tubes (). The duct tubes () may have circular or flattened cross-sections.
