The when that sheet and the second fin reaching certain length, then heat transfer effect just increases the most inconspicuous, is primarily due to along with first
Fin and the second fin length increase, more and more lower in the temperature of fin end, along with temperature is reduced to certain journey
Degree, then can cause the heat transfer effect inconspicuous, also add the cost of material on the contrary and considerably increases occupying of radiator
Space, meanwhile, in heat transfer process, if the spacing between the second fin is the least, also easily causes the deterioration of heat transfer effect, because of
For along with the increase of radiating tube length, in air uphill process, boundary region is thickening, causes boundary region between abutting fins mutual
Overlapping, deteriorate heat transfer, radiating tube length is the lowest or spacing between the second fin causes the most greatly heat exchange area to reduce, affects
