A plate and frame heat exchanger is a compact heat exchanger where thin corrugated plates are stacked in contact with each other, and the two fluids flow separately along adjacent channels in the corrugation. The closure of the stacked plates may be by clamped gaskets, brazed (usually copper brazed stainless steel), or welded (stainless steel,...

The hairpin heat exchanger design is similar to that of double pipe heat exchangers with multiple tubes inside one shell. The design provides the flexibility of a U-tube design with an extended shell length that improves the exchanger’s ability to achieve close temperature approaches.   Advantages Good counter current or co-current flow –...

Double pipe heat exchangers are the simplest of all types. They are fabricated from two pieces of pipe – one inside the other. One fluid flows through the inner pipe while the second fluid flows through the annulus between the pipes Advantages •Inexpensive •True counter current or co-current flow •Easily designed for high pressure service...

Shell and tube heat exchanger The principle components are: •shell •shell cover •tubes •channel •channel cover •tube sheet •baffles, and •nozzles Other components include tie-rods and spacers, pass partition plates (channel partitions), impingement plates, longitudinal baffles, sealing strips, and supports

Shell and tube heat exchangers have the following advantages:
