Learn more about plate heat exchangers.

Plate heat exchangers are now used in tandem with tubular heat exchangers in many different industries. So what is this device? What are the structures, types, and advantages? These will be important issues that we need to explore in detail shortly.

What are plate heat exchangers?

Plate heat exchangers are one of the most common types of heat exchanger employed today; the other common type of heat exchanger is the shell and tube heat exchanger. The spiral heat exchanger is also used for industrial applications, but its use is minor compared to the other two types of heat exchanger.

Plate heat exchangers have gained widespread application throughout the engineering world because they are efficient, robust, and relatively easy to maintain.

Plate Heat Exchanger (PHE) Components

Plate heat exchangers consist of relatively few parts. Because plate heat exchangers are used for transferring heat, they require inlets and outlets where the flowing mediums -or fluids- can enter and leave the heat exchanger. A fluid may be a liquid or a gas. As fluids are often assumed to be liquid only, we will use the term flowing medium to avoid confusion.

Gaskets and plates are used to separate the flowing mediums and prevent them mixing; gaskets are adhered to one side of each plate only. The plates hang upon a carry bar and are pressed together using clamping bolts.

A plate heat exchanger is a device that heats or dissipates heat by allowing two fluids to come into contact with each other through a metal plate surface. The product structure consists of standard sized metal plates interspersed with sealing rings to increase heat transfer optimally.

Normally this equipment is used for low pressure liquid medium below 20bar. Plate heat exchangers are widely used in industries such as:

• Applications in Ships
• Applications in the chemical industry
• Steel processing industry
• Electrical industry
• Paper industry.
• Textile industry.
• Food & Beverage Production
• HVAC
• Etc….

Classification of plate heat exchangers

Plate heat exchangers have many different types based on construction and welding technology. The most prominent to mention are:

• Plate heat exchanger using Gasket.
• Helical and flat plate heat exchangers.
• Full and semi-welded plate heat exchangers.

Depending on the requirements and needs of users, you can choose a device with a suitable design.

How does plate heat exchanger work?

Gasketed plate heat exchangers (GPHE) optimize heat transfer. Corrugated sheets make it easy to transfer heat from one gas or liquid to another.

Gasketed plate heat exchangers have elastic gaskets. They seal channels and direct vehicles into alternative channels. The plate pack is located between the frame plate and the pressure plate. It is then compressed by bolts between the plates.

The upper bar supports the channel and the pressure plate. They are then fixed in one position by a lower guide on the support column. This design is easy to clean and modify (by removing or adding panels easily).

Here are three steps to assemble the plate heat exchanger gasket

The heat transfer area of the gasketed plate heat exchanger is from the corrugated iron sheets. They are located between the frame and the pressure plates. The spacers act as seals between the plates.

The liquid flows upstream through the heat exchanger. This provides the most efficient thermal performance. It also allows for very close temperature access. Example of temperature difference between inlet and outlet service environment.

Plate heat exchanger gasket:

For viscous or heat-sensitive environments cold fluids are connected to hot liquids. This minimizes the risk of media overheating or freezing. gasket of plate heat exchanger with many alternating large ones

Plates come in a variety of pressing depths, V-angle patterns and wave shapes. All designed for optimal performance. Depending on the application, each product line has its specific sheet features.

The distribution area ensures the liquid flows to the entire heat transfer surface. This helps to avoid deposits that can cause deposits.

Highly turbulent flow between plates leads to higher heat transfer and pressure drop. Customizable thermal designs. Suitable for different applications for maximum thermal efficiency with lowest pressure drop.

With the wide variety of plate heat exchangers available, there are pros and cons of choosing a gasketed plate heat exchanger.

Classification of plate heat exchangers

Plate heat exchangers are currently divided into different types based on construction and welding technology. The most prominent to mention are:

• Plate heat exchanger using Gasket.
• Shape  spiral and flat shape.
• Sealed and semi-welded plates.

Advantages of plate heat exchangers

Plate heat exchangers have flexible operation. Compared with products with a beam-tube design, a plate heat exchanger shows the following outstanding advantages:

Talking about design, this device has a thin and light structure, so it is easy to disassemble and maintain during use.
Cleaning the heat exchanger does not take too much time and effort
With a large contact surface, the plate heat exchanger helps the heat transfer process take place better than the tubular product.
This is one of the top reasons why the product is so popular among users.
Diversity in materials: panels can be made from SS304, SS316, Titanium. Gaskets EPDM, NBR, Viton etc….
