Refrigerant module of integrated thermal management system for vehicle

A refrigerant module for an integrated thermal management system for a vehicle, the refrigerant module comprising:

• a compressor comprising:
• a first refrigerant intake port through which a refrigerant is drawn;
• and
• a first refrigerant discharge port through which the refrigerant is discharged after being compressed;
• a condenser comprising:
• a second refrigerant intake port through which the refrigerant discharged from the compressor is drawn;
• and
• a second refrigerant discharge port through which the refrigerant is discharged after being heat-exchanged;
• an expansion valve comprising:
• a third refrigerant intake port through which the refrigerant discharged from the condenser is drawn;
• and
• a third refrigerant discharge port through which the refrigerant is discharged after being expanded;
• an evaporator comprising:
• a fourth refrigerant intake port through which the refrigerant discharged from the expansion valve;
• and
• a fourth refrigerant discharge port through which the refrigerant is discharged after being heat-exchanged;
• a vapor-liquid separator comprising:
• a fifth refrigerant intake port through which the refrigerant discharged from the evaporator is drawn;
• and
• a fifth refrigerant discharge port through which a liquid refrigerant and a vapor refrigerant separated from the refrigerant are discharged;
• and
• a heat exchanger configured to perform a heat exchange between the refrigerant discharged from the condenser and drawn into the expansion valve and the refrigerant discharged from the vapor-liquid separator and drawn into the compressor,
• wherein the heat exchanger comprises:
• a first flow path through which the refrigerant discharged from the condenser and drawn into the expansion valve flows;
• a second flow path through which the refrigerant discharged from the vapor-liquid separator and drawn into the compressor flows;
• a first inlet through which the refrigerant is introduced to the first flow path, the first inlet being open upward;
• a first outlet through which the refrigerant is discharged from the first flow path, the first outlet being open upward;
• a second inlet through which the refrigerant is introduced to the second flow path, the second inlet being open downward;
• a second outlet through which the refrigerant is discharged from the second flow path, the second outlet being open downward;
• and
• a first body and a second body in which each of the first flow path and the second flow path is halved in flowing directions of the refrigerant, and
• wherein:
• the heat exchanger and the expansion valve are disposed below the condenser and the evaporator,
• the first inlet of the first flow path provided in the heat exchanger is disposed directly below the second refrigerant discharge port provided in the condenser,
• the third refrigerant intake port of the expansion valve is disposed directly above the first outlet of the first flow path provided in the heat exchanger,
• the second refrigerant discharge port of the condenser and the third refrigerant intake port of the expansion valve are indirectly connected through the first flow path of the heat exchanger such that the refrigerant discharged from the condenser passes through the first flow path of the heat exchanger and then draws into the expansion valve,
• the first refrigerant discharge port of the compressor and the second refrigerant intake port of the condenser are directly connected,
• the third refrigerant discharge port of the expansion valve and the fourth refrigerant intake port of the evaporator are directly connected,
• the fourth refrigerant discharge port of the evaporator and the fifth refrigerant intake port of the vapor-liquid separator are directly connected,
• the fifth refrigerant discharge port of the vapor-liquid separator and the first refrigerant intake port of the compressor are indirectly connected through the heat exchanger,
• the first flow path and the second flow path are formed on both sides of a heat exchange region such that the heat exchanger is configured to perform the heat exchange between the refrigerant flowing through the first flow path and the refrigerant flowing through the second flow path in the heat exchange region,
• the first inlet and the second outlet are formed in a first side of the first body,
• a first flange connected to the second body is formed on a second side of the first body,
• a second flange coupled to the first flange of the first body is formed on a first side of the second body, and
• the second inlet and the first outlet are formed in a second side of the second body.
