摘要： A fin-tube type heat exchanger includes a large number of plate fins arranged in parallel to each other at predetermined intervals for allowing an air stream to flow between them, and heat exchanging tubes having an outer diameter Do and extending through the plate fins in a direction at right angles thereto. The heat exchanging tubes are set in rows spaced apart by a pitch L.sub.1 in a direction parallel to an air stream as represented by1.2 Do .ltoreq.L.sub.1 .ltoreq.1.8 Do,and are spaced in each of the rows by a pitch L.sub.2 in a direction perpendicular to the air stream as represented by2.6 Do .ltoreq.L.sub.2 .ltoreq.3.3 Do.Each of the plate fins is formed, between the heat exchanging tubes, with a plurality of cut and raised portions open to the air stream and protruding alternately is opposite directions from a base plate of the plate fin. The number of cut and raised portions increase from central portions between adjacent heat exchanging tubes in each row towards the leading and trailing edges of the plate fin.

摘要： A fin tube heat exchanger is used in an air conditioner or the like and comprised of a plurality of fin plates spaced at regular intervals in parallel with one another, a plurality of heat exchanger tubes arranged in at least one row and extending through the fin plates in a direction perpendicular to the direction in which the fin plates extend, a plurality of raised strips formed on each fin plate in a direction perpendicular to an air flow and raised out of their original plane, and at least one draining passage formed on each fin plate and extending along the center line of the row of the heat exchanger tubes. In this heat exchanger, air is allowed to flow between the fin plates whereas a fluid medium is allowed to pass in the heat exchanger tubes. Each raised strip has two leg portions inclined with respect to the direction of the air flow. Furthermore, the raised strips in one row near to a longitudinal edge of the fin plate are increased in number as compared with those in another row near to the center line of the row of the heat exchanger tubes. No raised strip is formed in the draining passage.

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。

摘要： A fin tube heat exchanger is internally provided with a plurality of plate-shaped and regularly spaced fin members, a plurality of heat exchanger tubes inserted into through-holes defined in each fin member and a plurality of raised pieces formed in each fin member in a plurality of rows. The raised pieces in the same row are raised from a fin base in a direction opposite to the direction in which the raised pieces in adjacent rows are raised. The number of the raised pieces in each row is gradually increased as their row is located farther from a common center line of the through-holes. The raised pieces are integrally formed with and raised from the fin base between adjacent heat exchanger tubes so that two slits defined between the fin base and each raised piece may be open against the air flow.
