    • A heat exchanger including plate fins and, the tubes fins being stacked at respective intervals relative to one another, and heat exchanger tubes penetrating the fins in a fin-stacking direction. The heat exchanger exchanges heat between fluids flowing, respectively, inside and outside the heat exchanger tubes, through the heat exchanger tubes and the fins. Each of the fins includes cut-raised portions with a bridge shape having leg and beam segments. The cut-raised portions associated with each of the heat exchanger tubes are located substantially only in a region of the fin satisfying Ws=(1−φ)Dp+φD φ>0.5, where Ws is spread width of the cut-raised portions in a direction (column direction) extending along an end of the fin on the upstream side of the second fluid, and D is outer diameter of the heat exchanger tube. Dp is alignment pitch of the heat exchanger tubes in the column direction.
    • 一种热交换器,其包括板翅片,并且所述管翅片相对于彼此以相应的间隔堆叠,以及在翅片堆叠方向上穿透所述翅片的热交换器管。 热交换器通过热交换器管和翅片在热交换器管内部和外部流动的流体之间交换热量。 每个翅片包括具有腿和梁段的桥形的切割凸起部分。 与每个热交换器管相关联的切起部分基本上仅位于满足<?in-line-formula description =“In-line formula”end =“lead”>> Ws =(1 -phi)Dp + phiD <?in-line-formula description =“In-line Formulas”end =“tail”?> <?in-line-formula description =“In-line Formulas”end =“lead”?> phi> 0.5,<?in-line-formula description =“In-line Formulas”end =“tail”?>其中Ws是沿着沿着端部延伸的方向(列方向)上的切割部分的展开宽度 翅片在第二流体的上游侧,D是热交换器管的外径。 Dp是热交换器管在列方向上的对准间距。
