(54) HEAT EXCHANGER, HEAT EXCHANGER UNIT, AND REFRIGERATION CYCLE DEVICE


(57) Provided is a heat exchanger having flat tubes (41) and fins (206). Each fin includes a fin body (207) that has a plate shape, a flat tube insertion portion (209) formed on the fin body, and a communication portion (213), which extends vertically on the other side in the horizontal direction from the tube insertion portions and which has a first plane portion parallel to the vertical and horizontal direction. The communication portion is formed with a condensed water guide portion (217) bent in a direction intersecting the first plane portion, that extends continuously over the vertical direction, and in which a cross-sectional shape, when the condensed water guide portion is cut in a plane orthogonal to the vertical direction, is uniform in the vertical direction.
