  • Publication number: 20230251005
    Abstract: A refrigerator includes a cabinet configured to define a low-temperature storage space and a machine room, in which a compressor is disposed; and a condenser disposed in the machine room. The condenser includes a header comprising a first header and a second header, which are spaced apart from each other, a plurality of tubes configured to connect the first header to the second header, and a heat exchange fin disposed between the tubes spaced apart from each other. The header includes a baffle configured to partition an inner space of the header so as to guide a flow direction of a refrigerant, each of the tubes includes a passage in which a hollow is defined so that the refrigerant flows, and the passage has a volume that gradually decreases along a flow path of the refrigerant.

  • Patent number: 11624542
    Abstract: A refrigerator includes a main body defining a storage space, a cryogenic freezing compartment having an insulation space that is independent with respect to the storage space, an evaporator disposed inside the storage space to cool the storage space, and a thermoelectric module assembly disposed at one side of the cryogenic freezing compartment so that the cryogenic freezing compartment is cooled to a temperature less than that of the storage space. The thermoelectric module assembly includes a thermoelectric module, a cold sink coming into contact with a heat absorption surface of the thermoelectric module and disposed in the cryogenic freezing compartment, and a heat sink coming into contact with a heat generation surface of the thermoelectric module. The heat sink is cooled by introducing a refrigerant supplied to the evaporator.

  • Patent number: 11353248
    Abstract: A refrigerator includes: a cabinet for defining a storage space and a machine room; a compressor disposed in the machine room; a machine room cover for shielding a machine room opening; a base pan in the machine room; a condenser including: headers mounted on the base pan and extending to intersect the base pan; a plurality of tubes connecting the headers; and heat exchange fins disposed between adjacent tubes; and fixing parts protruding upward from the base pan and fixing the condenser by restraining a lower end of each header, wherein insertion holes opened toward the machine room opening are defined in the fixing parts, wherein the condenser is able to move to pass through the machine room opening, and wherein the lower end of each header is inserted and mounted into each insertion hole and is separated by exiting each insertion hole by the movement of the condenser.
