Abstract
A heat exchanger (100) includes a housing (10), a first manifold (20), a second manifold (30, 130) and a core (40). The housing (10) defines an enclosure and comprises nozzles (14, 16) for ingress and egress of coolant inside the housing (10). The first manifold (20) includes ports (222) and channels (242) in fluidic communication with the corresponding ports (222). Each channel (242) includes different sets of apertures (244). The second manifold (30, 130) is disposed substantially opposite to the first manifold (20). The core (40) includes heat exchange tubes (42) in fluid communication with the first manifold (20) and the second manifold (30, 130). The different set of apertures (244) configure fluid communication between the channels (242) and the heat exchange tubes (42) based on operative configuration of the ports (222) controlled by a controller (60) to define the number of passes through the core (40).
