Abstract
A heat exchanger includes a shell, a coiled tube, and a swirler. The shell has an inlet and an outlet and forms a cavity. A first of a liquid refrigerant and a vapor refrigerant enters the inlet of the shell. The coiled tube is positioned within the cavity and is connected to an inlet tube from outside the shell and an outlet tube to outside the shell. A second of the liquid refrigerant and the vapor refrigerant enters the inlet tube of the coiled tube. The swirler is arranged adjacent the inlet of the shell and is dimensioned to distribute the first of the liquid refrigerant and the vapor refrigerant across the coiled tube.
