The plate type or corrugated type should be fixed according to the actual needs of the stainless steel tube heat exchanger. For situations where the flow rate is large and the pressure drop is small, the heat exchanger should choose a plate type with low resistance, and a plate type with large resistance should be selected. According to the heat exchanger fluid pressure and temperature , make sure to choose the detachable or brazed type. When determining the heat exchanger plate type, it is not appropriate to choose a plate with a single plate area that is too small to avoid too many plates, the flow rate between the heat exchanger plates is too small, and the heat transfer coefficient is too low. This problem should be paid more attention to larger heat exchangers.
The process combination should be calculated based on heat transfer and fluid resistance, and determined according to the requirements of the process conditions. Try to make the convective heat transfer coefficients in the cold and hot water flow channels of the stainless steel tube heat exchanger equal or close to obtain good heat transfer effects. Because when the convection heat transfer coefficient on both sides of the heat transfer surface of the heat exchanger is equal to or close to the heat exchanger manufacturer, the heat transfer coefficient is obtained. Although the flow rate between the heat exchanger plates is not equal, the calculation of heat transfer and fluid resistance is still performed at the average flow rate. Since the heat exchanger“U”The single-flow nozzle is fixed on the pressure plate and is easy to disassemble and assemble.
