HEAT EXCHANGER

摘要

A heat exchanger is adapted to be used in a vapor compression system, and includes a shell, a distributing part, a tube bundle and a trough part. The shell has a longitudinal center axis extending generally parallel to a horizontal plane. The distributing part is configured and arranged to distribute a refrigerant. The tube bundle includes a plurality of heat transfer tubes disposed below the distributing part so that the refrigerant discharged from the distributor is supplied onto the tube bundle. The heat transfer tubes extend generally parallel to the longitudinal center axis. The trough part extends generally parallel to the longitudinal center axis under at least one of the heat transfer tubes to accumulate the refrigerant therein. The trough part at least partially overlaps with the at least one of the heat transfer tubes when viewed along a horizontal direction perpendicular to the longitudinal center axis.
