Integrated thermal management module for vehicle

A method of operating an integrated thermal management module for a vehicle, the method comprising:

• exchanging, using a refrigerant heat exchanger, heat of a refrigerant discharged from an evaporator with heat of the refrigerant having a flow path between a condenser and an expansion valve;
• introducing the refrigerant discharged from the evaporator to an internal space of a gas-liquid separator after the exchanging of the heat of the refrigerant discharged from the evaporator with the heat of the refrigerant having a flow path between the condenser and the expansion valve;
• and
• supplying a portion of the refrigerant discharged from the evaporator that is in a gas state from the internal space to a compressor, wherein the refrigerant heat exchanger comprises:
• a first channel through which the refrigerant discharged from the evaporator is discharged to the internal space of the gas-liquid separator;
• a second channel through which the refrigerant having a flow path between the condenser and the expansion valve is discharged to the expansion valve;
• and
• a partition wall provided between the first channel and the second channel to separate the first channel and the second channel from each other;
• wherein a cross-sectional area of each of the first channel and the second channel has a circular shape;
• and
• wherein the partition wall is configured to cross a center of a circle of the circular shape.

An integrated thermal management module for a vehicle, the integrated thermal management module comprising:

• a gas-liquid separator having an internal space configured to accommodate a refrigerant discharged from an evaporator, the gas-liquid separator being configured to supply to a compressor a portion of the refrigerant discharged from the evaporator that is in a gas state in the internal space;
• and
• a refrigerant heat exchanger provided on a refrigerant inlet side of the gas-liquid separator, the refrigerant heat exchanger being configured to exchange heat of the refrigerant discharged from the evaporator with heat of the refrigerant having a flow path between a condenser and an expansion valve before the refrigerant discharged from the evaporator is introduced into the internal space of the gas-liquid separator, the refrigerant heat exchanger comprising:
• a first channel through which the refrigerant discharged from the evaporator is discharged to the internal space of the gas-liquid separator;
• a second channel through which the refrigerant having a flow path between the condenser and the expansion valve is discharged to the expansion valve;
• and
• a partition wall provided between the first channel and the second channel to separate the first channel and the second channel from each other,
• wherein each of the first channel and the second channel has a spiral shape, and wherein a first inlet portion of the first channel is disposed on a border portion of the spiral shape of the first channel, a first discharge portion of the first channel is disposed on a center portion of the spiral shape of the first channel, a second inlet portion of the second channel is disposed on a center portion of the spiral shape of the second channel, and a second discharge portion of the second channel is disposed on a border portion of the spiral shape of the second channel.
