Main Features
Great
logarithmic average temperature difference:
Plate heat exchanger can realize full
counter current form; the temperature correction coefficient is 1.
High
heat transfer coefficient:
The corrugation of the sheet in plate
heat exchange can make fluid generate turbulent flow with minor Reynolds
number; its heat transfer coefficient is 3-5 times as large as that of
shell-and-tube heat exchanger, reaching 7,000W/m2K at the most.
Small
floor area:
Plate heat exchanger features compact
structure. The heat-exchanging area per unit volume is 2-5 times as large as
that of shell-and-tube heat exchanger; the floor area occupied by plate heat
exchanger is approximately one fifth to one tenth of the area occupied by
shell-and-tube heat exchanger, given that the same heat exchange task is
fulfilled by them.
Light
weight and low price:
The sheet in plate heat exchanger is
only 0…
