摘要： PURPOSE: Refrigerant leakage-preventing structure of a heat exchanger for a refrigerator is provided to prevent a refrigerant from leaking minutely between banks of tubes and headers of a condenser joined by thermal fusion and from flowing to the outside of the condenser along the outer wall of tubes. CONSTITUTION: A heat exchanger for a refrigerator comprises a condenser condensing a refrigerant compressed under high temperature and high pressure from a compressor and an evaporator evaporating the refrigerant decompressed under low temperature and low pressure from an expansion valve. The condenser is formed by interconnection of banks of tubes(118) made of plastic and headers(120) made of plastic through thermal fusion. In refrigerant leakage-preventing structure of the heat exchanger, spiral refrigerant leakage-preventing grooves(115) are formed to the outer walls of the ends of the tubes of the condenser in which a refrigerant comes, to prevent the refrigerant from leaking out between the banks of and the header when the refrigerant compressed from the compressor comes in the condenser. Refrigerant leakage-preventing parts(121) are formed to the header, so that a header injection liquid can close up the refrigerant leakage-preventing grooves while flowing and being cooled in the refrigerant leakage-preventing grooves, in double injection of the header in the refrigerant leakage-preventing grooves.

摘要： An exchange apparatus comprised of hollow thermoplastic tubes infusion bonded into a thermoplastic material is disclosed. In a preferred embodiment the hollow tubes are shaped by plaiting the tubes into cords and then thermally annealing the cords to set the crests and bends of the plait. The cords provide improved flow distribution of fluid about the hollow tube tubes in the exchange apparatus. The exchange apparatus is chemically inert and is useful for cross flow filtration, as well as heat and mass transfer in harsh chemical environments.
