摘要： A heat exchanger is provided to guide air flowing among tubes to rear parts of the tubes and reduce pressure loss in spite of a high flow rate of the air, thereby improving thermal conductivity and the operation efficiency of the compressor. A heat exchanger includes a plurality of fins(110) for heat transmission, and a plurality of tubes(30). The fins respectively have top peak parts(112a-112c) and bottom peak parts(114a,114b) connecting the top peak parts to each other. One(112b) of the top peak parts, positioned in the middle has a height(H1b) smaller than those(H1a) of the others, so that air flowing among the tubes becomes flowing to rear parts of the tubes smoothly.
