    • A heat exchanger including plate fins stacked at respective intervals relative to one another, and heat exchanger tubes penetrating the fins in. The heat exchanger exchanges heat between first and second fluids flowing, respectively, inside and outside the heat exchanger tubes. Each of the fins includes a substantially planar main body and cut-raised portions extending from the main body and disposed at an upstream side of flow of the second fluid. Each of the cut-raised portions corresponds to a respective heat exchanger tube and includes first and second opposed side ends connected to the main body of the fin. The first side end is nearer to the corresponding heat exchanger tube than is the second side end, the first side end is longer than the second side end, and the first side end is disposed at a downstream side of the flow of the second fluid, facing the corresponding heat exchanger tube.
    • 一种热交换器,其包括相对于彼此以相应间隔堆叠的板状翅片以及穿透翅片的热交换器管。热交换器在分别在热交换器管内和外部流动的第一和第二流体之间交换热量。 每个翅片包括基本平坦的主体和从主体延伸并设置在第二流体的流动的上游侧的切割部分。 每个切起部分对应于相应的热交换器管,并且包括连接到翅片的主体的第一和第二相对的侧端。 第一侧端部比第二侧端部更靠近相应的热交换器管,第一侧端部比第二侧端部长,第一侧端部配置在第二流体的流动的下游侧, 面对相应的热交换器管。

    • 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。

    • A tube expanding apparatus includes mandrels, each mandrel having a billet on a leading end; a reciprocating actuator for supporting rear ends of the mandrels, the reciprocating actuator being supported to reciprocate in an axial direction of hairpin tube straight portions; a pressure cylinder for raising and lowering the reciprocating actuator and expanding the straight portions by pressing the billets into the hairpin tube straight portions; hairpin receivers for supporting curved portions of hairpin tubes; a fin receiver for supporting a lower end portion of the laminated radiating fins; and a hydraulic cylinder for raising and lowering the fin receiver in the axial direction of the hairpin tube straight portions. The hydraulic cylinder lowers the fin receiver to a predetermined position as the mandrels descend and the billets begin to be inserted into the hairpin tubes.
