Types of Heat Exchangers
Types of Heat Exchangers
Based on the design characteristics indicated above, there are several
different variants of heat exchangers available. Some of the more common variants
employed throughout industry include:
1) Shell and tube heat exchangers
2) Double pipe heat exchangers
3) Plate heat exchangers
4) Condensers, evaporators, and boilers
5) Shell and Tube Heat Exchangers
The most common type of heat exchangers, shell and tube heat
exchangers are constructed of a single tube or series of parallel tubes (i.e., tube bundle) enclosed within a sealed, cylindrical pressure vessel (i.e., shell). The design of these devices is such that one fluid flows through the smaller tube(s), and the other fluid flows around its/their outside(s) and between it/them within the sealed shell. Other design characteristics available for this type of heat exchanger include finned tubes, single- or two-phase heat transfer, countercurrent flow, cocurrent flow, or crossflow arrangements,
and single, two, or multiple pass configurations.
Some of the types of shell and tube heat exchangers available include
helical coil heat exchangers and double pipe heat exchangers, and some of the applications include preheating, oil cooling, and steam generation. Shell and tube heat exchanger applications A closeup view of a heat exchanger tube bundle.

Double Pipe Heat Exchangers
     A form of shell and tube heat exchanger, double pipe heat exchangers employ the simplest heat exchanger design and configuration which consists of two or more concentric, cylindrical pipes or tubes (one larger tube and one or more smaller tubes). As per the design of all shell and tube heat exchangers, one fluid flows through the smaller tube(s), and the other fluid flows around the smaller tube(s) within the larger tube.
     The design requirements of double pipe heat exchangers include characteristics from the recuperative and indirect contact types mentioned previously as the fluids remain separated and flow through their own channels throughout the heat transfer process. However, there is some flexibility in the design of double pipe heat exchangers, as they can be designed with cocurrent or countercurrent flow arrangements and to be used modularly in series, parallel, or series-parallel configurations within a system. For example, Figure 4, below, depicts the transfer of heat within an isolated double pipe heat exchanger with a cocurrent flow configuration.
Plate Heat Exchangers
     Also referred to as plate type heat exchangers, plate heat exchangers are constructed of several thin, corrugated plates bundled together. Each pair of plates creates a channel through which one fluid can flow, and the pairs are stacked and attached—via bolting, brazing, or welding—such that a second passage is created between pairs through which the other fluid can flow.
     The standard plate design is also available with some variations, such as in plate fin or pillow plate heat exchangers. Plate fin exchangers employ fins or spacers between plates and allow for multiple flow configurations and more than two fluid streams to pass through the device. Pillow plate exchangers apply pressure to the plates to increase the heat transfer efficiency across the surface of the plate. Some of the other types available include plate and frame, plate and shell, and spiral plate heat exchangers.

Condensers, Evaporators, and Boilers
     Boilers, condensers, and evaporators are heat exchangers which employ a two-phase heat transfer mechanism. As mentioned previously, in two-phase heat exchangers one or more fluids undergo a phase change during the heat transfer process, either changing from a liquid to a gas or a gas to a liquid.
    Condensers are heat exchanging devices that take heated gas or vapor and cool it to the point of condensation, changing the gas or vapor into a liquid. On the other hand, in evaporators and boilers, the heat transfer process changes the fluids from liquid form to gas or vapor form.

Other Heat Exchanger Variants
     Heat exchangers are employed in a variety of applications across a wide range of industries. Consequently, there are several variants of heat exchangers available, each suitable for the requirements and specifications of a particular application. Beyond the variants mentioned above, other types available include air cooled heat exchangers, fan cooled heat exchangers, and adiabatic wheel heat exchangers.
