Heat Exchanger Bundle And Shell

  Shell and tube heat exchangers are also known as tube-and-tube heat exchangers. The partition wall heat exchanger is a heat transfer surface which Heat Exchanger Bundle And Shellis closed on the wall surface of the tube bundle in the shell.The heat exchanger has the advantages of simple structure, low cost, wide flow cross section and easy cleaning of scale; however, the heat transfer coefficient is low and the floor space is large. It can be made of various structural materials (mainly metal materials) and can be used under high temperature and high pressure.

  The bundle and the shell play a very important role in the use of the heat exchanger, and some work is done by these two components.The requirements of the heat exchanger for the bundle and the shell are also relatively high.it will affect the effect of the cold and heat exchange of the equipment if it is not suitable.

  In general, the heat exchanger consists of a bundle of plates and a shell.The cold flow enters the bundle plate path from the bottom of the device and flows out from the top of the device,The heat flow enters the shell side from the upper side opening and flows out from the lower side opening, and the two fluids are totally countercurrent heat exchange in the sheet bundle.An expansion joint is provided at the lower end of the bundle to solve the thermal expansion problem.
