What's plate-and-shell heat exchanger

  The plate-and-shell heat exchanger consists of a pressure vessel casing and a heat transfer plate bundle.The shell shape of the shell-and-plate What's plate-and-shell heat exchangerheat exchanger is similar to that of the shell-and-tube heat exchanger. The shell is subjected to the operating medium pressure, but there is no large flange for equipment commonly used in shell-and-tube heat exchangers.The heat transfer plate bundle is formed by welding hundreds of stainless steel corrugated plates together and hanging in the casing.The cold fluid enters the bundle plate from the bottom of the unit and exits from the top of the unit.The hot fluid enters the shell side from the upper side of the device and flows out from the lower side of the device. The two fluids are fully countercurrently exchanged in the bundle.The flow path of the plate is designed to be corrugated, and the adjacent plates are opposite in direction, and the corrugated tops of the mutually intersecting corrugations form contact points for withstanding the pressure difference of the heat exchange medium of the hot and cold fluid.The sheet runners can be designed in a variety of equivalent diameters and shapes depending on the operational requirements and the nature of the media. The heat exchange area of a single unit is generally greater than 800, and the maximum has reached 15000
