1. A heat exchanger for receiving an airflow having an uneven intensity distribution across the heat exchanger and for flowing refrigerant within the heat exchanger, the heat exchanger comprising:
sections of microchannel tubes for flowing refrigerant through at least one pass through the heat exchanger, wherein the sections are configured according to the airflow across the heat exchanger;
at least two inlets in fluid communication with two non-adjacent sections for flow in a first pass via a first header, wherein the at least two inlets comprises a first inlet and a second inlet;
two additional sections located between the sections from the first pass for flowing refrigerant in a second pass through the heat exchanger to a second header;
an additional section for a third pass wherein refrigerant from the second pass sections combine into the third pass section and further comprising an outlet in fluid communication with the third pass section via the second header; and
additional individual sections for flowing refrigerant in additional passes each before flowing refrigerant into the third pass section such that the number of sections and passes from the first inlet to the outlet is different than the second inlet.
