Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small floor space, wide application and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of tube heat exchanger, Covering an area of one third of that of the tubular heat exchanger. and the heat recovery rate can be as high as 90%.II.Classification according to structure  1.Removable plate heat exchanger (also called plate heat exchanger with sealing gasket)  2.welding plate heat exchanger,   3. spiral plate heat exchanger,  4.Plate-coil heat exchanger (also called honeycomb heat exchanger).III. design feature  1.High efficiency and energy saving: its heat transfer coefficient is 3000 ~ 4500 kcal/m2 c h, which is 3~5 times higher than that of shell-and-tube heat exchanger. 2.Compact structure: the plates of the plate heat exchanger are closely arranged. Compared with other types of heat exchangers, the plate heat exchanger occupies less area and space, and the size of plate heat exchanger with the same area and heat exchange capacity is only 1/5 of that of shell-and-tube heat exchanger.. 3.Easy cleaning and convenient disassembly: the plate heat exchanger clamps the clamped plate by clamping bolts, so it is convenient to disassemble and open for cleaning at any time. At the same time, due to the smooth surface and high turbulence, it is not easy to scale. 4.Long service life: the plate heat exchanger is made of stainless steel or titanium alloy plates, which can resist all kinds of corrosive media, and the rubber gasket can be replaced at will, and it is convenient for disassembly and maintenance. 5.Strong adaptability: the plates of the plate heat exchanger are independent components, and the flow can be increased or decreased freely as required, with various forms, it can be suitable for various different technological requirements.  6.There is no cross flow of liquid, and the sealing groove of the plate heat exchanger is provided with a liquid drain channel, so that all kinds of media will not collude, and even if there is leakage, the media will always be discharged outward.IV. application area   Plate heat exchangers have been widely used in metallurgy, mining, petroleum, chemical industry, electric power, medicine, food, chemical fiber, papermaking, textile, shipping, heating and other departments, and can be used for heating, cooling, evaporation, condensation, sterilization, waste heat recovery etc.V.Key points of product selection  1.The control parameters of plate heat exchanger are heat exchanger material, working pressure, design temperature, etc. 2. When selecting a heat exchanger, we should try our best to make the side with small heat transfer coefficient get large flow velocity, and try our best to make the heat transfer coefficients on both sides of the two fluid heat exchange surfaces equal or similar to improve the heat transfer coefficient. The temperature of the fluid heated by the heat exchanger should be 10ºC lower than the saturation temperature at the outlet pressure of the heat exchanger and lower than the working temperature of the water pump used for secondary water. 3.Fluid containing silt and dirt should be filtered and then enter the heat exchanger.  4.When selecting plate heat exchanger, the flow velocity at the interface of fluid on the side with small temperature difference should not be too large, and it should meet the requirements of pressure drop.  5.For the case of large flow and small allowable pressure drop, the plate with small resistance should be selected, otherwise, the plate with large resistance should be selected.   6.According to the fluid pressure and temperature, choose detachable or electric welding.   7. It is not advisable to choose plates with too small veneer area, so as to avoid too many plates, too small flow rate between plates and reduce the heat transfer coefficient.   8.The heat transfer medium of plate heat exchanger should not be steam.Detailed Photos Product ParametersPlate heat exchanger product selection parameters tableModels   Angle holeDiameter (mm)"Ripple depth(mm)""Corner hole centre distance   (mm)""Exter
