1. A condenser comprising a plurality of heat exchange tubes disposed in parallel such that the heat exchange tubes are spaced apart from one another in a vertical direction and extend in a left-right direction; and header tanks which extend in the vertical direction and to which left and right end portions of the heat exchange tubes are connected, in which three or more heat exchange paths each formed by a plurality of heat exchange tubes successively arranged in the vertical direction are juxtaposed in the vertical direction, wherein
the condenser has a group composed of at least two heat exchange paths which are successively arranged and which include a heat exchange path at the upper end, and at least one heat exchange path is provided below the group; in the group, refrigerant is caused to flow from a heat exchange path at one of upper and lower ends toward a heat exchange path at the other end; first and second header tanks are provided at the left or right end of the condenser, heat exchange tubes which form a heat exchange path located on the downstreammost side of the group with respect to a refrigerant flow direction and heat exchange tubes which form the heat exchange path located below the group being connected to the first header tank, and heat exchange tubes which form all the remaining heat exchange path(s) being connected to the second header tank; the first header tank is disposed on the outer side of the second header tank with respect to the left-right direction, has an upper end located above a lower end of the second header tank, and has a function of separating gas and liquid from each other and storing the liquid; the first heat exchange tubes connected to the first header tank have projecting portions at their ends located on the side toward the first header tank, the projecting portions extending outward, with respect to the left-right direction, of second-header-tank-side end portions of the second heat exchange tubes connected to the second header tank, the first heat exchange tubes being longer than the second heat exchange tubes by a length of the projecting portions in the left-right direction and being positioned downstream of the plurality of second heat exchange tubes with respect to a flow of refrigerant, fins being disposed between the projecting portions of adjacent first heat exchange tubes; and the projecting portions of all the first heat exchange tubes and the fin between the projecting portions of the adjacent first heat exchange tubes form a heat exchange section. |
