摘要

Examining the pros and cons of each type of exchanger can help you find the one that's right for your process. All shell-and-tube heat exchangers can be categorized into two broad categories: U-tube and straight tube. For clarity of definition, the Tubular Exchanger Manufacturers Association (TEMA) has defined the mechanical designs for front-end head types, shell types and rear-end head types by a lettering system called the nomenclature chart. While there are many different types of U-tube and straight-tube exchangers, for the purpose of this article, we will be comparing BEU and BEM designs. These are the most commonly used and, generally, the least expensive of the options. Throughout this article, BEM designs are interchangeable with NEN and AEL designs: They have the same explored benefits and limitations, albeit with a different channel layout. Similarly, BEU designs are interchangeable with AEU designs.
