摘要： 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.

摘要： A heat exchanger including a plurality of flat tubes having first and second open ends is disclosed. First and second header pipes are disposed at the first and second open ends of the tubes. The header pipes are constructed of a central tube, and inner and outer brazing layers brazed to the inner and outer surfaces of the central tubes, respectively. The header pipes also include a plurality of slots. The open ends of the tubes are fixedly disposed through the slots such that the interior of each flat tube is in fluid communication with the interior of the header pipes. A plurality of fin units are disposed between the plurality of flat tubes. Each of the plurality of flat tubes is coated with a layer of zinc. The layer of zinc extends throughout the exterior surfaces of the tubes except for first and second uncoated areas disposed adjacent each open end of the tubes. The first and second uncoated areas extend from a location adjacent where the exterior surface of either the outer brazing layer or the central tube contacts the exterior surfaces of the tubes, to the location of the open ends of the tubes.
摘要翻译：公开了一种包括多个具有第一和第二开口端的扁平管的热交换器。第一和第二总管设置在管的第一和第二开口端。集管由中心管构成，内外钎焊层分别钎焊到中心管的内表面和外表面。集管还包括多个槽。管的开口端通过狭槽固定设置，使得每个扁平管的内部与集管的内部流体连通。多个翅片单元设置在多个扁平管之间。多个扁平管中的每一个涂覆有一层锌。除了在管的每个开口端附近设置的第一和第二未涂覆区域之外，锌层都延伸穿过管的外表面。第一和第二未涂覆区域从邻近外部钎焊层或中心管的外表面与管的外表面接触的位置延伸到管的开口端的位置。

摘要： A heat exchanger includes a pair of header pipes, a plurality of heat-transfer tubes parallel to each other, a block provided at a position on a single or two or more heat transfer tubes between the header pipes and having at least one of an inlet port and an outlet port for a heat exchange medium. The block is freely located at a desired medial position between the header pipes as required. Since the inlet port or outlet port is located at an optimum position between the header pipes, connection of a pipe or tube thereto can be easily accomplished.
摘要翻译：热交换器包括一对总管，多个彼此平行的传热管，设置在总管之间的单个或两个或更多个传热管上的位置处的块，并且具有至少一个入口端口和用于热交换介质的出口。根据需要，该块可自由地定位在总管之间的所需中间位置。由于入口端口或出口端口位于集管之间的最佳位置，所以可以容易地实现管或管的连接。
