ABSTRACT:
A heat exchanger includes a pair of header pipes, a plurality of flat heat-transfer tubes parallel to each other, a plurality of radiation fins provided on the sides of the flat heat-transfer tubes, an additional flat heat-transfer tube disposed adjacent to the end flat heat-transfer tube, having a path cross-sectional area larger than those of the flat heat-transfer tubes and being connected to one of the header pipes and a joint unit, and an additional radiation fin provided on at least one side of the additional flat heat-transfer tube. The vacant space in the space for installation of the heat exchanger can be utilized as an additional heat exchange portion formed by the additional tube and fin; and the effectiveness of the heat exchanger can be efficiently increased even if the space for the installation is small or limited.
