    • A heat exchanger 1 includes a condenser section 2, a subcooling section 3, and a gas-liquid separator section 4 which is provided between the condenser section 2 and the subcooling section 3; and is configured to allow a refrigerant to flow out of the condenser section 2 into the subcooling section 3 through the gas-liquid separator section 4. The gas-liquid separator section 4 includes a pair of headers 21, 22 and liquid receiving tubes 23 which are disposed between the headers 21, 22. A refrigerant inlet 32 is provided on an upper wall 21a of one of the headers 21 of the gas-liquid separator section 4 and a refrigerant outlet 33 is provided on a lower wall 22b of the other header 22 of the gas-liquid separator section 4. The gas-liquid separator section includes flow rate lowering means which has a mesh material 34 spread across the refrigerant inlet 32 and a passage extending member 35 which is formed in the other header 22 so as to enclose the refrigerant outlet 33 and to extend the length of the passage through which the refrigerant moves from the refrigerant inlet 32 to the refrigerant outlet 33. This heat exchanger 1 exhibits enhanced gas-liquid separation effect in the gas-liquid separator section.

    • PROBLEM TO BE SOLVED: To provide a heat exchanger having an enhanced gas-liquid separation effect in a gas-liquid separation part.
      SOLUTION: A heat exchanger 1 is provided with a condenser part 2, a subcooling zone 3, and a gas-liquid separation part 4 arranged between the condenser part 2 and the subcooling zone 3, and is constituted to make a refrigerant flowing out of the condenser part 2 flow into the subcooling zone 3 through the gas-liquid separation part 4. The gas-liquid separation part 4 comprises a pair of headers 21, 22 and a liquid receiving tube 23 arranged between the both headers 21, 22. A refrigerant inflow port 32 is formed in an upper wall 21a of the one header 21 of the gas-liquid separation part 4 and a refrigerant flow-out port 33 is provided in a lower wall 22b of the other header 22 of the gas-liquid separation part 4. The gas-liquid separation part is provided with a flow velocity lowering means comprising a mesh 34 provided in the refrigerant inflow port 32, and comprising a flow passage length extending member 35 provided in the other header 22 to surround the refrigerant outflow port 33 and to extend a length of the flow passage for the refrigerant flowing in from the refrigerant flow-in port 32 up to the refrigerant outflow port 33.
