  • Patent number: 10094602
    Abstract: A condenser includes a condensation section, a super-cooling section, and a liquid receiving section. Refrigerant from heat exchange tubes of a first heat exchange path of the condensation section flows into those of a second heat exchange path through the liquid receiving section. The liquid receiving section includes a first space for receiving refrigerant from the heat exchange tubes of the first heat exchange path, a second space which is located above the first space and in which refrigerant from the first space is separated into gaseous and liquid phases, and a third space which is located below the first space, which receives refrigerant from the second space, and from which refrigerant flows to the heat exchange tubes of the second heat exchange path. A first partition member between the first space and the second space has a throttle for refrigerant flowing from the first space into the second space.
