Taking the guide groove type PSHE as the object,based on the domestic and international research achievements,the paper discusses in detail the structure and the working principle of PSHE,the selection of process composition on plate side and shell side as well as the relevant theories of the heat transfer calculation and pressure drop calculation. The paper also presents the detailed steps and relevant formula on the thermodynamic calculation and points out the problems which shall be noted during the period of the design and calculation for PSHE,such as the plate model selection,the choice of the fouling factor value,the control of errors and so on. In addition,the paper describes the performance test method of PSHE as well as the solving method of the heat transfer criterion equation,summaries the influences of plate structure parameters on flow and heat transfer and analyzes the phenomenon of the flow maldistribution at the inlet of the shell side. Finally,the paper forecasts the development prospects of PSHE and indicates the integrated design,complete-set assembly,and central intellective control will become the key development direction for PSHE.
