Plate and frame heat exchangers are extensively used in manufacturing processes such as chemicals, food production, nuclear plants and industrial refrigeration.The Plate and Frame heat exchangers consist of a number of specially corrugated stainless steel plates assembled in a frame and bolted between two pressure plates, one of which is fixed and the other adjustable. Plate and Frame heat exchangers are also extremely space-efficient, easy to maintain, and can be inspected and cleaned without removing the plates from the frame and also provide cross-contamination prevention. Plate and Frame Heat Exchangers are an alternate type of heat exchanger which utilizes a quantity of identical corrugated metal plates arranged in a parallel pattern separated by gaskets.

Plate and Frame Heat Exchanger Advantages

Gaskets are used as seals to prevent leaking.

Expansion and adding units together is simple because of the construction.

A plate-and-frame heat exchanger transfers heat from one fluid to another.

The higher thermal performance makes the plate heat exchanger more cost effective.

It has higher heat transfer coefficients, space requirements are less than a shell-and-tube unit.

Plate heat exchangers are available in a wide number of alloys to handle highly corrosive fluids.

Design:

The plate heat exchanger (PHE) is a specialized design well suited to transferring heat between medium- and low-pressure fluids. The plates produce an extremely large surface area, which allows for the fastest possible transfer. Making each chamber thin ensures that the majority of the volume of the liquid contacts the plate, again aiding exchange. This design guideline covers the selection and sizing methods for plate heat exchangers which are commonly used in typical industrial processes. It helps engineers to understand the basic design of different types of heat exchanger, and increases their knowledge in selection and sizing. A Plate heat exchanger is a device for heat transfer from one medium to another. Selection and sizing are related each other; changing in heat exchanger component, such as tube pattern and baffle, would affect the calculation. Some required data is commonly pictured in a graph or listed in a table; they are already attached in this guideline as well. To do manual calculation, it is mentioned before, iteration is needed. This guideline gives some approximation values as a boundary for iteration. The step by step sizing method is also explained in this guideline to simplify the calculation.In heat exchanger design, there are three types of flow arrangements: counter-flow, parallel-flow, and cross-flow. In the counter-flow heat exchanger, both fluids entered the exchanger from opposite sides. In the parallel-flow heat exchanger, the fluids come in from the same end and move parallel to each other as they flow to the other side. The cross-flow heat exchanger moves the fluids in a perpendicular fashion. Compare to other flow arrangements counter flow is the most efficient design because it transfers the greatest amount of heat.In the plate heat exchanger, the fluid flows through baffles. This causes the fluids to be separated by plates with a large surface area. This type of heat exchanger is typically more efficient than the shell and tube design.
