simple HX surface area question
simple HX surface area question
(OP)
This may sound like a very stupid question, but if I have (10) one square foot aluminum plates stacked in a plate-type HX, is my total heat exchange area 10 square feet, or 20 square feet? I assume it's 10?





RE: simple HX surface area question
think about the flow passages of the 2 different fluids in your case.
also, plate HEX's generally have smaller flow passages, hence allow for greater surface area per volume of space occupied. there are shortcomings of these type exchangers as well.
good luck!

So that's interesting, I count the surface area of BOTH sides of a single .036" thick plate...which means my HX should only be half as big and half as expensive as I thought...
RE: simple HX surface area question
In heat transfer calculations both parallel surfaces of a flat thin plate, or a tube for that matter, are counted as one, perpendicular to heat flow, as explained by pmover.

If you're calculating the heat transfer, you have to look at each piece of the puzzle. If the term is some industry standard term, then we're back to what is the definition of the term.
