ABSTRACT:
A heat exchanger contains one or more heat exchange plates having on a common facial surface thereof a first heating fluid facial subchannel set containing at least one heating fluid facial subchannel and a first cooling fluid facial subchannel set containing at least one cooling fluid facial subchannel; wherein the heating fluid facial subchannel set and the cooling fluid facial subchannel set are mutually aligned in a heat exchange relationship on the common facial surface of the heat exchange plate(s). In one embodiment, the heat exchanger contains at least one pair of heat exchange plates, wherein a first plate in the pair has on a front facial surface thereof a first-plate heating fluid facial subchannel set and a first-plate cooling fluid facial subchannel set, and a second plate in the pair has on a front facial surface thereof a second-plate heating fluid facial subchannel set and a second-plate cooling fluid facial subchannel set, wherein the first-plate heating fluid facial subchannel set is aligned in heat exchange relationships with the first-plate cooling fluid facial subchannel set and the second-plate cooling fluid facial subchannel set, and the second-plate heating fluid facial subchannel set is aligned in heat exchange relationships with the second-plate cooling fluid facial subchannel set and the first-plate cooling fluid facial subchannel set.
