The tube bundle heat exchanger

In a tube bundle heat exchanger, two media separated by the pipe wall are moved alongside each other. The heat of the two media will be exchanged if a temperature difference exists between them.

A tube bundle normally consists of 3 components: the front head, the shell and the tube bundle. One medium flows through the tubes, while the second medium flows through the shell room. Depending on the design, so-called baffle plates are used in the shell. The medium that flows through the shell is guided by the baffle plates in such a way that it flows as transvere as possible to the bundle tubes. This increases the quality of the heat transfer. The better the heat transfer the more compact are the apparatuses.

The tube side as well as the shell side can be designed either single or multiple pass in tube bundle heat exchangers. The speed and the pressure loss of the flowing media are decisive for the above. The number of passes has an effect on the length of the apparatuses.The tube bundle heat exchanger can be used as cooler or as heater for liquid gaseous media.
