摘要： A method of manufacturing a fin-tube heat exchanger which includes a multiplicity of plate fins arranged in a plurality of rows disposed at a predetermined pitch in the direction of air flow, and a jointless refrigerant pipe extending through the plate fins in a zigzag manner. Pipe-receiving holes are formed in each plate fin in an offset manner relative to the center of the plate fin. The plate fins are then placed in fin-receiving grooves formed in a straight fin positioning fixture at predetermined spacings such that the same longitudinal ends of the plate fins of alternating rows appear on the same side of the fin positioning fixture and such that the pipe-receiving holes are linearly aligned. The refrigerant pipe is inserted into the pipe-receiving holes and is expanded to make tight and close contact with the plate fins. The refrigerant pipe is bent in a zigzag manner so that the straight portiions of the pipe occupy corners of rectangles and so that a predetermined spacing is provided between the plate fins of adjacent rows. Finally, a twist is imparted to the refrigernat pipe to line up the plate fins and arrange the pipe such that the straight portions of the pipe are positioned in a staggered manner, as viewed in the direction of the rows.
摘要翻译：一种翅片管式热交换器的制造方法，其特征在于，具有沿空气流动方向以规定的间距排列成多列的多个板翅片，以锯齿状延伸穿过所述板翅片的无接头制冷剂配管。在每个板翅片中相对于板翅片的中心以偏移的方式形成管接收孔。然后将板状翅片以预定的间隔放置在形成在直翅片定位固定器中的翅片容纳槽中，使得交替排的板翅片的相同纵向端部出现在翅片定位夹具的同一侧上，接收孔线性对齐。制冷剂管插入管接收孔中并膨胀以与板翅紧密接触。制冷剂管以锯齿形的方式弯曲，使得管的直线部分占据矩形的角部，并且在相邻行的板状翅片之间设置预定间隔。最后，将弯曲管赋予回流管，以使板状翅片排列成一排，并且使管道的直线部分在行的方向上以交错的方式定位。
