20. A combined core microchannel heat exchanger comprising:
a first plurality of microchannel tubes extended between, and in fluid communication with, a first inlet header and a first outlet header arranged in a vapor compression circuit,
a second plurality of microchannel tubes extended between, and in fluid communication with, a second inlet header and a second outlet header arranged in a free cooling circuit, wherein the vapor compression circuit is fluidly isolated from the free cooling circuit and the second plurality of microchannel tubes are interleaved between adjacent microchannel tubes of the first plurality of microchannel tubes, and
a plurality of fins disposed between the second plurality of microchannel tubes and the first plurality of microchannel tubes at least along a portion of an effective length of the first plurality of microchannel tubes.
