Zusammenfassung:	The present disclosure is directed to multichannel tubes with flow path inlet sections that allow refrigerant to enter the flow paths through an outer wall of the multichannel tubes. In certain embodiments, a portion of the outer wall is removed to expose the flow paths to a distribution chamber within an inlet manifold divided into an inlet section and a distribution section by a distributor. According to certain embodiments, the inlet section may be designed to have a relatively small cross-sectional area that promotes mixed phase flow of liquid and vapor refrigerant. The multichannel tubes extend into the distribution section to partition the distribution section into a series of distribution chambers defined by a pair of adjacent tubes, the distributor, and the inlet manifold. Within each distribution chamber, the refrigerant may be directed into the multichannel tubes through the flow path inlet sections of the multichannel tubes.
