1. A heat exchanger comprising:
a main body comprising an inlet plenum and an outlet plenum at a first end, a header at a second end, and at least one elongated shaft extending from the outlet plenum to the header;
at least one heat pipe coupled to the header of the main body, a portion of the at least one heat pipe positioned within the at least one elongated shaft of the main body defining an annular space between the at least one heat pipe and the at least one elongated shaft; and
a flow skirt comprising a manifold located between the inlet plenum and the outlet plenum of the main body and at least one elongated tube extending from the manifold, the at least one elongated tube positioned within the annular space between the at least one heat pipe and the at least one elongated shaft, dividing the annular space into two concentric annular channels comprising an inner annular channel and an outer annular channel.
