How Plate Type Heat Exchanger Works

How Plate type Heat Exchanger works

A heat exchanger is a piece of equipment used to transfer heat from one medium to another via the use of convection.

There are two basic kinds of heat exchangers: reciprocating and condensing.

Direct heat exchange occurs when the two mediums are in direct touch with one another and so produce heat. For example, a cooling tower in which water cools by coming into direct touch with air.

Through the use of split media, indirect heat exchange is achieved.

A Plate type Heat Exchanger

A Plate type Heat Exchanger operates according to the same principles as a shell and tube design, with the exception that instead of tubes and an outer shell, the fluids in a plate heat exchanger flow via a number of channels that are separated by a stack of the plate.

It is possible to increase the amount of heat that can be dispersed by a Plate type of Heat Exchanger by increasing the number of plates in the stack or by extending the length and breadth of the plates. As a result of this design, plate heat exchangers are more compact than shell and tube heat exchangers.

Additionally, because they are typically manufactured from stainless steel, they are an obvious choice for many industries, including food and beverage processing, chemicals and petrochemicals, pharmaceuticals, and dairy, where copper and aluminum are not permitted.

The characteristics and advantages of Plate type Heat Exchanger;

• a solution that is both affordable and effective
• Temperature and pressure ratings that are very high
• There are several different types of connectors available, including welded, threaded, and flanged.
• Design in a little package
• Construction is made of stainless steel.
• Thermal Efficiency at a High Level
• Jackets with insulation are available in a variety of sizes.

How it works

The heat transfer efficiency of gasketed plate heat exchangers (GPHE) is maximized. The corrugated plates make it simple to transfer heat from one gas or liquid to another via the system.

Elastomeric gaskets are used to seal the plates of a gasketed plate heat exchanger. These act as a seal between the channels and guide the media onto different pathways. The plate pack is located between the frame plate and a pressure plate on the frame plate side.

It is then crushed using bolts that are inserted between the plates. The channel and pressure plate are held in place by the top carrying bar.

They are then held in place by a lower guiding bar on the support column, which is attached to the support column. This design is simple to clean and maybe easily adjusted (by removing or adding plates).

The following are the three stages involved in assembling a gasketed plate heat exchanger:

• It is the corrugated plates that provide the heat transfer area in a Heat Exchanger Spares. These are located in the space between the frame and the pressure plates. The gaskets between the plates serve as a seal between them.
• Fluids pass through the heat exchanger in a counter-current fashion. This results in the most energy-efficient thermal performance possible. It also makes it possible to get extremely near to the target temperature. For example, the temperature differential between the service media entering and departing the service system.
• When dealing with heat-sensitive or viscous material, the cold fluid must be combined with hot fluid. Thus, the danger of overheating or freezing the medium is reduced to a minimum.
