Air cooler header sizing

[juanq]

In this moment I looking for some method to determinate the dimensions of the headers (high and width in croos section) of any Air Cooler Heat Exchangers. I don't have software to do it. But I'd like to know some formula or practical method to calculate these dimensions

sizing of header box depends on tube lay out. Could you please furnish exteme dimensions of tube lay out ie. length and depth. A plug type header can be sized by adding due manufacturing clearances to the tube lay out. Next we must know the nozzle connection sizes coming on the header ie., No. & NB of nozzles. please furnish above inf.
