A particular design well suited for transferring heat between medium- and low-pressure fluids is the plate heat exchanger (PHE). When a more compact product is needed or where heat exchange between high-pressure fluids is necessary, welded, semi-welded, and brazed heat exchangers are employed. Instead of a pipe running through a chamber, there are two alternating chambers that are typically shallow in depth and are divided by a corrugated metal plate at their greatest surface. Metal plates are pressed together to create the plates that go into a plate and frame heat exchanger. Due to its resistance to corrosion, strength, and capacity to tolerate high temperatures, stainless steel is a frequently used metal for the plates.

Plate heat exchangers optimation

Two crucial aspects, the quantity of heat transfer and the pressure drop, must be taken into account in order to improve PHEs. The amount of heat transfer must be raised while pressure drops must be lowered. Because corrugated plates are used in plate heat exchangers, there is a substantial flow resistance and high friction loss. Thus, one should take into account both considerations while designing plate heat exchangers. There are numerous correlations and chevron angles for plate heat exchangers for a wide variety of Reynolds numbers. One of the most crucial factors in heat transmission and pressure drop in plate heat exchangers is the plate geometry, yet this aspect is not precisely prescribed. Due to the limited channel between the plates in corrugated plate heat exchangers, there is a high pressure capacity and the flow becomes turbulent along the path. Therefore, compared to other types of heat exchangers, it needs higher pumping power. As a result, greater heat transfer and decreased pressure drop are desired. For industrial applications where pressure drop is a factor, the design of the plate heat exchanger is crucial.
