Condenser

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;

• header tanks which extend in the vertical direction and to which left and right end portions of the heat exchange tubes are connected;
• and fins each disposed between and brazed to heat exchange tubes adjacent to each other in the vertical direction, in which three or more exchange paths each formed by a plurality of heat exchange tubes successively arranged in the vertical direction are juxtaposed in the vertical direction, wherein
• first and second header tanks are provided at a left or right end of the condenser, first heat exchange tubes which form at least two heat exchange paths successively arranged and including a heat exchange path at a lower end of the condenser being connected to the first header tank, and second heat exchange tubes which form a heat exchange path(s) provided above the heat exchange paths formed by the first heat exchange tubes connected to the first header tank 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;
• and
• a corrosion prevention member having a function of corroding sacrificially for the first heat exchange tubes is disposed in a clearance between the projecting portion of an upper-end first heat exchange tube and the lower end of the second header tank.
