Main Features:
|
|
Great logarithmic average temperature difference:
|
Plate heat exchanger can realize full countercurrent 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 0.5-0.8mm in thickness. The heat-exchanging area needed by it is smaller than that needed by shell-and-tube heat exchanger, given that the same heat-exchange task is fulfilled by them. The weight of plate heat exchanger is only around one fifth of the weight of shell-and-tube heat exchanger.
|
|
Small temperature difference at the end:
|
As for water-water heat exchange, the lowest temperature difference at the end can be lower than 1℃, which is extremely beneficial to the recovery of low-temperature heat energy.
|
|
Low dirt coefficient:
|
The dirt coefficient of plate heat exchange is small for the following reasons: Violent turbulent flow of fluid causes low-possibility deposition of impurities; the dead zone of inter-sheet channel is small; the heat-exchanging surface made of stainless steel is smooth, which results in less corrosive attaching.
|
|
Heat exchange with multiple media:
|
Plate heat exchange allows for heat exchange with three or more media via the middle clapboard, which is extensively applied in milk product processing techniques.
|
|
Convenient cleaning:
|
To clean the sheet mechanically, unscrew the clamping bolt in plate heat exchanger to loosen the binding of plate and then unload the sheet, featuring extremely convenient maintenance.
