PLATE HEAT EXCHANGER 

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…
