Heat Exchangers, Their Types And Applications

A heat exchanger can be simply referred to a piece of equipment built to efficiently transfer heat from one medium to another. Heat exchangers are used in a wide variety of applications such as home heating, refrigeration, air conditioning, petrochemical plants, refineries as well as in natural gas processing. In many industrial processes a heat exchanger helps in using the wasted heat from one process to be utilized in another process which saves a lot of money while being efficient at the same time.

There are multiple types of heat exchangers available depending upon their applications in various parts of the industry.

1) Shell and Tube heat exchangers: To make it simple, this type of heat exchanger works with a series of tubes containing the fluid that must be either heated or cooled and these tubes run in a shell or a much larger tube containing another liquid that either heats up and warms the tubes or absorbs and cools the fluid running in the smaller tubes. Shell and Tube heat exchangers work better in high pressure and demanding environments.

2) Plate heat exchanger: These heat exchangers work with a line-up of multiple thin and closely placed plates which have a very large surface area and fluid flow passages for better heat dispersion. Plate heat exchangers are more practical compared to Shell and Tube ones in applications where there is a space restriction.

3) Adiabatic wheel heat exchanger: This type of a heat exchanger uses a separate material which can either be a solid or a liquid material to store the held heat which then moves to another side of the heat exchanger to be released.

4) Plate fin heat exchanger: Plate fin heat exchangers are usually made of aluminum alloy with varied designs such as cross flow, counter flow, along with different types of fins which result in very effective heat transfer. They however offer a disadvantage at times in the procedure of servicing them correctly because of the extremely thin plates.
