<p>A heat exchanger configured so that a reduction in the heat exchange efficiency thereof is minimized and that water can be easily discharged from the tubes and the fins. A heat exchanger is provided with: tubes (110) having flat surfaces (115) facing each other with predetermined gaps provided therebetween; and fins (120) having bent sections (122 (122a, 122b)) and flat sections (121) which are formed alternately in the longitudinal direction, the bent sections (122 (122a, 122b)) being joined to the opposing flat surfaces (115) of the tubes (110). The fins (120) are each configured in such a manner that a predetermined range (bent section (122c)) of each of the bent sections (122a) in the lateral direction, the bent sections (122a) being in contact with one of the opposing flat surfaces (115), is bent toward the other of the opposing flat surfaces (115) and joined thereto to form a communication passage (125).</p> |
