Fin is a heat exchanger that affect the heat transfer coefficient of all-welded plate heat exchangers, one of the important components. Trades involving more than, the product is characterized by series, diversity. Diverse in form, size, fin 1o a variety of different sizes, and the huge demand for each day fin. As the market continues to expand, but also the emergence of new features: the same kinds of products due to the different heat transfer, fin size, only to change its pitch height, other dimensions remain basically unchanged. Pitch Hill flanging foot decision height. Such as the all-welded plate heat exchanger according to the conventional mold design, a pair of mold components, flanging foot due to a high degree of change, you have to replace the mold, then the fin varieties increased, the demand for increased mold, mold cost of providing high. In order to reduce die costs, as much as possible to reduce mold species, analysis of the components of the structural characteristics of the original mold structure improvements, enabling a variety of fin-Punch system.
    Is a medium-sized fins as shown in parts, part material is q235-a, material thickness o.3mm. Named according to their shape, x-type fins. Fin, for example, taking the children to explore the structure of the model improvements, to pitch fin punching a variety of purposes, as much as possible to reduce the number of molds and reduce costs.
    Fin spacing the main foot height of the decision by the flanging pin, now used in several series of parts are mostly there are changes in pitch, the other dimensions basically the same. At present there are on the x-type fin in terms of 2.5mm, 3mm, 4mm and so on three kinds of spacing. As the market continues to expand, is also to add new varieties. If you press the conventional mold design, punching three kinds of fin spacing on the all-welded plate heat exchangers need to make 3 molds, at least each sold separately prepare a mold with a maintenance turnaround, so the number of mold on a lot of high cost . According to the shape of fins to analyze the structural characteristics of touch with, to consider how to improve the structure makes - Vice-mold system can be washed several fin spacing.
