• a plurality of microchannel tubes extending between and in fluidic connection with an inlet header and an outlet header of the heat exchanger;
• an external distributor that comprises an inlet port and a plurality of outlet ports, wherein a plurality of feeder pipes is configured between the outlet ports of the first distributor and positioned along a length of the inlet header to enable flow of volumes of fluid from the external distributor into the inlet header;
• and
• an auxiliary header fluidically coupled to the outlet header using one or more tube stubs, the auxiliary header configured at a distance from the outlet header with the one or more tube stubs protruding from the outlet header and extending up to the auxiliary header forming an angle from a horizontal plane of the outlet header, wherein the auxiliary header is configured to receive and collect the fluid received in the outlet header.
