An inlet member having a refrigerant inflow passage which is open at opposite ends is joined to a condensation section inlet header of a condenser. An opening at one end of the refrigerant inflow passage serves as an inflow opening into which externally supplied refrigerant flows, and an opening at the other end serves as an outflow opening from which refrigerant flows out to the condensation section inlet header. The condensation section inlet header has an opening at a position offset from the longitudinal center toward the one end thereof. The inlet member has an insert portion which is inserted into the condensation section inlet header through the opening. The outflow opening of the refrigerant inflow passage is open to a single upward facing flat surface of the insert portion, and is oriented such that the refrigerant flows toward the longitudinal center of the condensation section inlet header.

a condensation section inlet header disposed such that its longitudinal direction coincides with a vertical direction;
a heat exchange path formed by a plurality of heat exchange tubes disposed parallel to one another such that their longitudinal direction coincides with a left-right direction and they are spaced from one another in the vertical direction, each of heat exchange tubes being connected, at one longitudinal end thereof, to the condensation section inlet header; and
an inlet member joined to the condensation section inlet header, the inlet member having a refrigerant inflow passage which is open at opposite ends thereof and through which refrigerant flows to a region within the condensation section inlet header, the region being offset from a longitudinal center of the condensation section inlet header toward one end of the condensation section inlet header,
an opening at one end of the refrigerant inflow passage of the inlet member serving as an inflow opening into which the refrigerant flows from the outside, and an opening at the other end of the refrigerant inflow passage serving as an outflow opening from which the refrigerant flows out to the condensation section inlet header, wherein
the condensation section inlet header has an opening formed in a circumferential wall of the condensation section inlet header at a position offset from the longitudinal center toward the one end of the condensation section inlet header;
the inlet member has an insert portion which is inserted into the condensation section inlet header through the opening;
the outflow opening of the refrigerant inflow passage is open to a surface of the insert portion; and
the outflow opening of the refrigerant inflow passage is oriented such that the refrigerant flows toward the longitudinal center of the condensation section inlet header.
2. The condenser according to claim 1 , wherein the outflow opening of the inlet member is located on a single flat surface of the insert portion, and a straight line orthogonal to the flat surface extends in the longitudinal direction of the condensation section inlet header.
3. The condenser according to claim 2 , wherein the straight line orthogonal to the single flat surface where the outflow opening of the inlet member is located is located on a plane perpendicularly intersecting an air-passing direction.
4. The condenser according to claim 3 , wherein the refrigerant inflow passage of the inlet member has a straight portion located on a side toward the outflow opening and having a predetermined length, and the straight portion is inclined such that the straight portion approaches the longitudinal center of the condensation section inlet header and the heat exchange tube while extending from an inflow opening side toward the outflow opening side.
5. The condenser according to claim 1 , wherein the outflow opening of the insert portion is located on a single flat surface of the insert portion, a straight line which passes through the center of the outflow opening and is orthogonal to the flat surface is inclined such that the distance of separation from a straight line which passes through the center of the outflow opening and extends in the longitudinal direction of the condensation section inlet header increases with the distance of separation from the flat surface toward the longitudinal center of the condensation section inlet header, and the two straight lines form a predetermined angle therebetween.
6. The condenser according to claim 5 , wherein the angle formed between the straight line orthogonal to the single flat surface of the insert portion where the outflow opening of the inlet member is located and the straight line extending in the longitudinal direction of the condensation section inlet header falls within a range of 0° to 45°, excluding 0°.
7. The condenser according to claim 5 , wherein the straight line orthogonal to the single flat surface of the insert portion where the outflow opening of the inlet member is located is located on a plane perpendicularly intersecting an air-passing direction.
8. The condenser according to claim 1 , wherein the inlet member has an auxiliary refrigerant inflow passage formed in the insert portion of the inlet member, one end of the auxiliary refrigerant inflow passage being open to a wall surface of the refrigerant inflow passage, the other end of the auxiliary refrigerant inflow passage being open to a surface of the insert portion which faces toward a side opposite the longitudinal center of the condensation section inlet header, and an opening at the other end of the auxiliary refrigerant inflow passage is smaller in size than the outflow opening.
