A heat exchanger system includes a core-in-shell heat exchanger and a liquid/gas separator. The liquid/gas separator is configured to receive a liquid/gas mixture and to separate the gas from the liquid. The liquid/gas separator is connected to the core-in-shell heat exchanger via a first line for transmitting gas from the liquid/gas separator to a first region in the core-in-shell heat exchanger and connected to the core-in-shell heat exchanger via a second line for transmitting liquid from the liquid/gas separator to a second region of the core-in-shell heat exchanger.

A refrigerant heat exchanger is provided and includes: a hollow container having a cylindrical shape; a plate stack disposed on an inner lower side of the hollow container, including plates each having a front side and a back side with a plurality of concavo-convex portions formed thereon which are stacked to form a first heat exchange flow passage through which a first refrigerant flows and a second heat exchange flow passage through which a second refrigerant flows; a supply pipe disposed in an interior space of the hollow container above the plate stack and configured to supply the first refrigerant to the plate stack; and a discharge pipe configured to exchange heat between the first refrigerant supplied from the supply pipe and the second refrigerant flowing through the plate stack and to discharge the first refrigerant.

A shell and plate heat exchanger includes a shell and a plate pack. The shell defines a cavity configured to receive a first fluid and a second fluid. The plate pack is arranged inside the cavity. The plate pack has a plurality of heat exchanger plates. Each of the heat exchanger plates has two sides facing in opposite directions in a thickness direction of the heat exchanger plate. At least one of the sides of at least one of the heat exchanger plates has a surface roughness of between 5 ?m and 100 ?m.

A refrigerant cycle system includes: a primary-side cycle of a vapor compression type that circulates a first refrigerant; a secondary-side cycle of a vapor compression type that circulates a second refrigerant; and a cascade heat exchanger that exchanges heat between the first refrigerant and the second refrigerant. The secondary-side cycle includes a secondary-side heat exchanger that uses cold or heat obtained by the second refrigerant from the cascade heat exchanger. The secondary-side heat exchanger includes a flat multi-hole pipe.

A distributor includes at least: a first flow path through which refrigerant flowing in from a refrigerant inflow unit flows in a first direction toward a heat transfer tube disposed on the side of a refrigerant outflow unit; two second flow paths branched from the first flow path; two third flow paths, through each of which the refrigerant flows in a second direction opposite to the first direction; two fourth flow paths, each of which is formed to protrude from a main body toward the second direction and through each of which the refrigerant flows in a third direction intersecting the two third flow paths; and two fifth flow paths, through each of which the refrigerant flows in the first direction.
