摘要： A heat exchanger includes a shell, a refrigerant distribution assembly and a heat transferring unit. The refrigerant distribution assembly includes a first tray part and second tray parts. The first tray part continuously extends generally parallel to the longitudinal center axis of the shell to receive a refrigerant that enters the shell. The second tray parts are disposed below the first tray part to receive the refrigerant discharged from first discharge apertures such that the refrigerant accumulated in the second tray parts does not communicate between the second tray parts. The second tray parts are aligned along a direction generally parallel to the longitudinal center axis of the shell. The heat transferring unit is disposed below the second tray parts so that the refrigerant discharged from second discharge apertures of the second tray parts is supplied to the heat transferring unit.

摘要： A flow distributor is adapted to distribute two-phase refrigerant into a plurality of flow paths. The flow distributor includes a tubular main body having a center axis, at least one inlet port, and a plurality of outlet ports. The inlet port is disposed in a lower portion of the main body in a state in which the center axis of the main body is oriented in a generally vertical direction. The inlet port has a center axis that is not parallel to and does not intersect with the center axis of the main body so as to generate an upward spiraling flow of the refrigerant within the main body. The outlet ports form a plurality of openings disposed in an upper portion of the main body in the state in which the center axis of the main body is oriented in the generally vertical direction, with all of the openings being at least partially arranged in a plane orthogonal to the center axis of the main body.

摘要： A fin tube heat exchanger has heat transfer fins disposed in an air flow and plural heat transfer tubes that are inserted in the heat transfer fins and disposed in a direction substantially orthogonal to a flow direction of the air flow. On the heat transfer fins, a set of guide fins and a set of guide fins arranged straightly from upstream to downstream in the flow direction of the air flow are formed, by cutting and raising, on the heat transfer fin surfaces on both sides of the heat transfer tubes. Straight lines that hypothetically interconnect the guide fins and the guide fins slant with respect to the flow direction of the air flow so as to guide the air flow in the vicinities of the heat transfer tubes to rear sides of the heat transfer tubes in the flow direction.
