  Heat exchangers are used in many industrial processes, such as refinery, ethylene, gas treatment, gas liquefaction, and polymer and power generation.The conventional shell-and-tube heat exchanger with segmental baffles is very versatile and hence is widely used, but it has some disadvantages over other types of heat exchanger.In particular, the shell-side flow path in a conventional shell-and-tube heat exchanger is wasteful on pressure drop, limits maximum thermal effectiveness, and encourages dead spots or recirculation zones where fouling can occur.
