1. A heat exchanger for vehicles configured to cool and condense a refrigerant through heat exchange with a coolant, comprising,
a condenser configured such that the coolant and the refrigerant perform heat exchange while flowing separately from each other, the condenser being formed by stacking a plurality of first heat exchange plates;
a gas-liquid separator configured to separate gaseous components from the refrigerant that has passed through the condenser;
a supercooler configured such that the coolant having passed the condenser and the coolant having passed the gas-liquid separator perform heat exchange while flowing in separately from each other, the supercooler being formed by stacking a plurality of second heat exchange plates; and
a connector that is interposed between the condenser and the supercooler and that forms a coolant passage allowing the coolant to flow from the condenser to the supercooler and a refrigerant passage allowing the refrigerant to flow from the condenser to the supercooler via the gas-liquid separator,
wherein the connector comprises a first intermediate plate and a second intermediate plate that are disposed in contact with each other,
wherein the refrigerant passage comprises a refrigerant discharge passage and a refrigerant return passage that are respectively formed by a recessed groove that is provided in at least one of a first surface of the first intermediate plate and a second surface of the second intermediate plate facing each other, and
wherein the recessed groove is formed by a dam that protrudes from the at least one of the first surface and the second surface,
wherein the first surface comprises a first embossed structure inside four side edges of the first surface, and the second surface comprises a second embossed structure inside four side edges of the second surface, and
wherein the first embossed structure and the second embossed structure are in contact with each other.
