1. A header for a heat exchanger comprising:
a heat exchanger in flow communication with the header, the heat exchanger configured to distribute fluid through a plurality of adjacent channels, the header connected between at least one heat exchanger inlet and a channel flow distributor;
a channel flow distributor comprising a plurality of secondary cavities disposed adjacent to and upstream of the heat exchanger in fluid communication with the channels
the header comprising a housing having a main cavity comprising an inlet port on one end of the housing and an outlet port on the opposite end of the housing;
the inlet port and the outlet port configured to generate a flowpath of fluid across the channel flow distributor secondary cavities;
wherein the vortical flows are induced in the secondary cavities to generate cross-step filtration and localized vortical cleaning for removal of a particulate matter and a fouling material.
