    • 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。
