Heat exchanger

1. A heat exchanger which includes a heat exchanger core constituted by a condenser section configured to condense a refrigerant and a sub-cooler section configured to supercool the refrigerant of liquid phase obtained by passing the refrigerant from the condenser section to a receiver tank so as to subject the refrigerant to gas-liquid separation, and in which an upper header tank and a lower header tank are connected to each other by a plurality of vertically extending tubes and each have an interior divided by a partition plate into a condenser header part associated with the condenser section and a sub-cooler header part associated with the sub-cooler section, the heat exchanger comprising:

a single refrigerant pipe configured to introduce the refrigerant into the receiver tank from the condenser header part; and

a mounting member configured to mount the receiver tank to the upper header tank,

wherein

the mounting member has a refrigerant inlet passage connecting the refrigerant pipe to an interior of the receiver tank and a refrigerant outlet passage connecting the interior of the receiver tank to the sub-cooler header part,

a location of a junction where the refrigerant pipe is connected to the condenser header part is adjustable, and

a position of the partition plates of the header tanks is adjustable.

2. The heat exchanger according to claim 1 , wherein the mounting member covers an upper end portion of the receiver tank.

3. The heat exchanger according to claim 2 , wherein the mounting member covers a horizontal end portion of the sub-cooler header part.

4. The heat exchanger according to claim 3 , wherein the mounting member has a retainer provided in the inlet passage and configured to prevent detachment of the refrigerant pipe.
