A condenser includes a condensation section, a super-cooling section located above the condensation section, and a liquid receiver. The liquid receiver has a first space communicating with the condensation section through a refrigerant inlet and a second space located above the first space and communicating with the super-cooling section through a refrigerant outlet. A partition member is provided in the liquid receiver in order to divide the internal space of the liquid receive into the first space and the second space. A suction pipe which is open at upper and lower ends thereof and which establishes communication between the first space and the second space is disposed in the first space of the liquid receiver. The partition member has an internal volume adjustment portion for increasing the internal volume of the first space and decreasing the internal volume of the second space.

Condenser

A condenser includes a condensation section, a super-cooling section located above the condensation section, and a liquid receiver. The liquid receiver has a first space communicating with the condensation section through a refrigerant inlet and a second space located above the first space and communicating with the super-cooling section through a refrigerant outlet. A suction pipe which is open at upper and lower ends thereof and which establishes communication between the first space and the second space is disposed in the first space. A tubular flow control member whose upper end is open is disposed around the suction pipe such that the refrigerant having flowed into the first space through the refrigerant inlet hits against the flow control member and changes its flow direction. Since the refrigerant inlet is located within the vertical range of the flow control member, the refrigerant hits against the flow control member.

A first header tank of a condenser serves as a condensation section outlet header section. A second header tank has lower end upper ends respectively located below and above the lower end of the first header tank. A portion of a second header tank located below the lower end of the first header tank serves as a super-cooling section inlet header section. The second header tank also serves as a reservoir section. The interior of the condensation section outlet header section of the first header tank communicates, through a communication section, with a portion of the interior of the second header tank, which portion is located above the lower end of the first header tank. A flow velocity reducing member is provided in the second header tank so as to reduce the flow velocity of liquid-phase dominant refrigerant which flows into the reservoir section through the communication section.
