The plate heat exchanger consists essentially of heat transfer
plates, gaskets and a clamping device. Thanks to its structure
and heat exchange principle, it is characterized by compact
structure, small floor area, high heat transfer coefficient and
operation flexibility, wide application range, small heat loss,
easy installation and cleaning, etc. The two mediums have
a mean temperature difference as small as 1ºC and heat
recovery efficiency higher than 99 percent. Based on the same
pressure loss, the plate heat exchanger has, compared with
a tubular heat exchanger, a heat transfer coefficient two
to four times higher, a one-third floor area and two-thirds
metal consumption.It is therefore an efficient and energy, material
and investment saving advanced heat exchanger. It is now widely
used in industrial fields such as chemical industry, petrochemical,
food, machinery, central heating, metallurgy, power, ships,
paper-making, textile, pharmaceutical industry, nuclear industry,
seawater desalination and combined heat and power generation to
meet the requirements of processes such as cooling, heating,
condensation, concentration, sterilization and residual heat
recovery. It has become a highly competitive product in the
heat exchanger field or evenly has replaced conventional tubular
heat exchangers. With its development, it will be used in more and
more fields. Table 1 Plate
