  • Air conditioner system having a refrigerant distributor and method of making same
    Patent number: 5743111
    Abstract: A heat exchanger, as mounted on the outdoor unit or indoor unit of an air conditioner system, is formed with a plurality of passages for a refrigerant. To this heat exchanger, there is connected a refrigerant distributor for distributing the refrigerant to the individual passages or for collecting the distributed refrigerant. This refrigerant distributor is constructed by soldering two corrugated plate members to form a refrigerant conduit between the corrugations. Before these plate members are soldered, the refrigerant conduit is either partially constricted to form a throttle portion or partially bulged to form a filter portion by fitting a filter member in the bulging portion when the plate members are soldered. Thus, the refrigerant distributor can set the diversion of the refrigerant to a predetermined ratio by the simple device while reducing the space and lowering the cost.
