plate heat exchanger for centralized heating of water, water, oil,
heat exchange, industrial hot water exchanger, bath boiler radiator
A detachable plate heat exchanger is made up of many heat -
exchange plates (thin metal sheets stamped with corrugated
grooves). These plates are sealed around the edges at certain
intervals by sealing gaskets and compressed by clamping studs. The
holes at the corners form continuous channels. The medium enters
the channels from the inlet and is distributed into the flow
channels between the heat - exchange plates. Each plate has a
sealing gasket, and the plates are placed alternately. Two kinds of
fluids enter their respective channels separately and are separated
by the plates. Generally, the two media flow counter - currently in
the channels. The hot medium transfers heat energy to the plates,
and the plates then transfer the heat energy to the cold medium on
the other side. In this way, the hot medium is cooled as its
temperature drops, and the cold medium is heated as its temperature
rises.
Its main features are as follows: high heat transfer coefficient;
convenient for maintenance and cleaning (this advantage has
relatively decreased since the emergence of THE); low fouling
factor; compact structure, small footprint, and light weight; easy
to change the heat - exchange area or process combination; small
terminal temperature difference, etc.
However, compared with semi - welded plate heat exchangers (SWPHE),
fully - welded plate heat exchangers (WPHE), and brazed heat
exchangers (CBE), detachable heat exchangers have lower temperature
and pressure - bearing capacities and poorer corrosion resistance.
Plate heat exchangers have been widely applied in sectors such as
metallurgy, mining, petroleum, chemical industry, power, medicine,
food, chemical fiber, papermaking, light textile, shipping, and
heat supply. They can be used for various scenarios including
heating, cooling, evaporation, condensation, sterilization, and
waste heat recovery.

Hundreds kinds of models are used in diferent areas and can supply
the customer wide range choice, especially the wide gap.t is also
called freeAow.fow channel gap is can be up to 12 18 to 22 mm,the
maximum fow gap 2 to 5 times ofnormal plate heat exchanger.And
there is litle contact point or no contact point between
plates.Wide gap plate is designed for iber or other liquid which
may jam the traditional plate heatexchanger, a high turbulence and
the characteristics of high heat transfer ,the operating cycle or
cleaning intervaltime is longer and cleaningeasierWidely used in
the paper making and food industry in addition,our large port plate
for customers to choose,350mm for shallow corrugation,450mm for the
depth corrugation,deep ripple'one time.greatly replace the current

Plate heat exchanger is a kind ofnew and high effect heat
exchanger, which is consis of a series of metal plates with some
corrugated form andthere is a rectangular channel between plates
and the media exchange heat through plates, Plate heat exchanger is
the perfect equipment oiheat exchange for fuid-fuid and fuid-gas,
ts advantages are high heat transfer eficiency, compact structure,
small occupied area, easy operation, wide range
ofapplication,little thermal losses, easy installation and removal
and long service life, in the case of same pressure drop,its
heattransfer coeffcient is 3-5 times than shel-and-tube heat
exchanger,its occupied area is one third ofshel-and-tube heat
exchanger,its metawastage is just two thirds of shell-and-tube heat
exchanger, the mean temperature difference ofthe two medila can be
1c, and the heat recoverefciency can be over 90%, Therefore, plate
heat exchanger is an advanced heat exchange equipment with high
eficiency, energy conservationeconomyofmaterials and investment
save.
Design
The main components of the Plate Heat Exchanger:
. The plate pack comprises of a number of heat plates, according to
the heat transfer surface required.
Gaskets on the plates ensure that the fuid channels are securely
sealed from each other.
The direction offow within the exchanger is determined by the
gasket.
The frame enclosing the plate pack is held together with tightening
bolts.
Connections for incoming and outgoing fuids are usually in the fxed
frame of the heat exchanger in case of multi pass flow,
connectionshave to be in the fxed frame and the movable frames.
