What is Heat Exchangers ,Their Types and Applications

A heat exchanger may be simply based on a device that is configured to efficiently transfer heat from one medium to another. Heat exchangers are used in a variety of applications, such as heating, cooling, air conditioning, petrochemical plants, refineries and natural gas processing. In many industrial processes allows a heat exchanger to use waste heat from one process to be used in another process, which saves a lot of money, while efficiently.

There are several types of heat exchangers available, depending on their application in various sectors of the industry.

Shell and Tube Heat Exchanger:

Simply put, this heat exchanger uses a series of tubes containing the liquid that must be either heated or cooled, and these tubes run into a bowl or pipe a lot more one another Liquid contains either heated and heated tubes or absorbed and cools the liquid in small tubes. Shell and tube heat exchangers work best in high pressure and demanding environments.

Plate Heat Exchanger:

This heat exchanger works with a network of a plurality of thin and close plates, which have a very large surface area of ​​the fluid passages and for a better distribution of heat. Plate heat exchangers are more convenient compared to hull and pipe applications in applications where there is a restriction of space.

Adiabatic Wheel Heat Exchanger:

This type of heat exchanger uses a separate material, which can be a solid or a liquid material to store heat retained, which moves to the other side of the heat exchanger to be released.

Finned Plate Heat Exchangers:

Finned Plate Heat Exchangers are generally made of aluminium alloy with different models such as cross-flow, counter-current, with different types of fins, which lead to a transfer Very effective heat. However, they offer a disadvantage at times in the maintenance procedure properly due to extremely thin plates.

What is a Heat Exchanger? And Types of Heat Exchangers

What is a Heat Exchanger?

A heat exchanger is a device for transferring heat to two or more fluids. In other words, the heat exchanger is used for the cooling and heating process. Fluids can be separated by solid walls to prevent mixing, or they can be in direct contact.

Types of Heat Exchanger

1. Shell and Tube Heat Exchangers:

Shell and tube heat exchangers consist of a large number of small tubes that are located inside a cylindrical shell. The tube is positioned into the cylinder using a tube bundle or "tube stack" which may have a fixed tube sheet (permanently attached to the body) or, in the case of a Thermex heat exchanger, the tube bundle may expand the tube bundle. It also shrinks under different thermal conditions and allows the tube bundle to be easily disassembled for repair and maintenance.

Benefits of Using Shell and Tube Heat Exchangers?

• Shell and tube heat exchangers have higher heat transfer efficiency.
• These heat exchangers are the best solution for swimming pool heating, mining machinery, hydraulic power packs and more.
• These heat exchangers can be easily removed. Therefore, cleaning and repair are easy.
• The heat exchanger is compact in size.
• The capacity of these heat exchangers can be increased by adding plates in pairs.
• These exchangers are affordable compared to plate coolers.
• Since the stress test is relatively simple, one can easily find the pipe leaks and fix them.
• These heat exchangers can be used in systems with higher operating temperatures and pressures.

2. Plate Heat Exchangers:

Plate heat exchangers operate in much the same way as shell and tube heat exchangers, using a series of stacked plates instead of tubes. Plate heat exchangers are typically brazed or gasketed depending on the application and fluid used. Its compact stainless steel construction makes it ideal for refrigerant or food and beverage processing.

3. Semi-welded Plate Heat Exchangers:

Semi-welded heat exchangers are used for both organic and inorganic chemical treatments when the chemicals involved limit the choice of gaskets that can be used or when the required design pressure is such that the fully gasketed plate and frame heat exchangers are insufficient.

Advantages of  Semi Welded Plate Heat Exchangers

• Easy to clean gasket exchange surface
• Low pollution tendency.
• Fast and economical installation.
• The heat transfer coefficient is high.
• Extremely resistant to corrosion.
• Easy to replace washers - combination washer frame.
