Aluminum micro-channel tube is a kind of high-precision extruded aluminum tube, also called multi-port extrusion tube (MPE tube) and an aluminum micro-channel tube. This flat, rectangular extruded tube is made of several channels that increase heat transfer through a higher surface-per-volume ratio.
