High Efficiency Stainless Steel Plate Heat Exchanger with Liquid Cooling
Product Description
Product Introduce
 
Plate 
heat exchanger is a new 
efficient
 and compact heat exchanger that has developed and extensively used in the recent decades. 
I
t consists of multiple parallel 
corrugated
-
surface
 thin metal sheets that overlap and are then fixed by lamp plates and bolts. 
T
he cold working fluid and the hot working fluid flow through the narrow and winding passage made of two neighboring plates alternately and realize cold and heat exchange through the plates separating the two working fluids.
T
he plate heat exchanger consists essentially of
 heat transfer plates, gaskets and a clamping device
.
T
hanks 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 
1
ºC
and 
heat recovery efficiency
 higher than 
99 percent
. 
B
ased 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 a two-thirds metal consumption. 
I
t is therefore an 
efficient
 and energy, material and investment saving advanced heat exchanger. 
I
t 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, sea water desalination and combined heat and power generation
 to meet the requirements of processes such as 
cooling, heating, condensation, concentration, sterilization and residual heat recovery
. 
I
t has become
a highly competitive product in the heat exchanger field or evenly has replaced conventional tubular heat exchangers. 
W
ith its development, it will be used in more and more fields.
 
 Plate and gasket
T
he plate materials and the gasket materials mainly depend on the corrosive properties and temperatures of the cold exchange medium and the heat exchange medium.
