Design Of A Plate & Frame Heat Exchanger
(OP)
What is the criteria for designing a plate & frame heat exchanger? Any literature I can read and some design equations would be very much appreciated.
Thank You
Thank You

A small correction on the terminology - they are just called plate exchangers. Plate and frame units usually refer to filter presses.

'Plate and frame' heat exchanger is often used to differentiate between it and 'brazed plate' heat exchagers.
There are other standards and organizations for this stuff, I just can't think of them now. Anyone?

Generally, shell and tube heat exchangers inadverstently design for disproportionate flow ratios between hot and cold side flow in a plate heat exchanger. This is because shell and tube design require high shell side flow to create as much trubulence as possible on the shell side.

It is really pretty good. I usually have to take an existing Hx and use it to back into a design but once I get it set up, it is pretty accurate when comparing it against vendor quotes.
I googled it and it is out there (and in a later version, it seems)- go get it.
Good luck!!

Brazed PHE's are cheap, but can not be repaired and cleaned very limited. Limited to small capacities, and thermal length.
Welded PHE's can withstand higher temperatures and pressures, like shell and tubes. There is also manufacturers (APV, Sondex, Tranter, Vahterus) that have plate and shell heat exchangers: high heat transfer coefficient, 1 side mechanical cleaning possible, mechanical properties (pressure / temperature) of a shell and tube.
Please note that a PHE is an excellent filter, however it is not designed for it. So if a fluid contains pulp or fibres, don't use it.
As someone explained above, each manufacturer has itsown design of plates, distribution area at the inlet of a plate, angle, plate gap, etc so you need to ask them for a design. Making your own design and then trying to buy it, will be loss of energy.
Can you mention your application.

GEA Ecoflex also has shell & plate designs as well.
PHE's are successful in applications where there are fibers - think sugar - but only because the passages are large and provisions to blackflow or blackflush are designed into the piping day one.
