Plate heat exchangers

 

What are plate heat exchangers?

A plate heat exchanger (PHE) is a heat exchanger that uses metal plates to transfer heat between two liquids by stacking several heat exchanger plates on top of each other. and let the liquid flow through each area plate heat exchanger British researcher Dr. Richard Seligman invented the first heat exchanger in 1923. Later in the year 2430, stainless steel plates are used to manufacture plate exchangers. heat and has been developed to withstand more pressure at the point of use.

Today's heat exchangers are powerful enough for both heating and cooling.

* Heat is transferred through a partition wall, usually made of some metal.

how does it work?

The working principle of plate heat exchanger is designed to optimize heat transfer. by bringing together several metal plates Then let the liquid flow through the gaps in each sheet alternately. Therefore, the two liquids do not come into direct contact with each other. Therefore, heat transfer takes place through the cross-sectional area of ​​each sheet. which plate heat exchanger It is designed with a corrugated embossing pattern to increase the contact area where gaskets are attached or welded together. Plate heat exchangers are then compressed together. To create a parallel flow channel arrangement of one fluid flowing in one channel and another flowing in another.

Strength

1) It has a high heat transfer coefficient. Because the plate heat exchanger is designed to allow liquids to flow in opposite directions. Small flow rate with high heat transfer coefficient. It is especially suitable for heat exchange of highly viscous liquids with precise heat transfer.

2) The required amount of heat transfer area can be adjusted by increasing or decreasing the plate heat exchanger.

3) The structure is small Can reduce installation costs, suitable for limited applications and are cheap.

4) Plate heat exchangers require a small installation space. This saves installation space. and can be installed vertically

5) It is environmentally friendly. Installation work requires very little equipment. Reduce costs incurred from machinery such as other expenses arising from the design, development, production, use, maintenance and various support etc.

Instructions

The liquid must be clean. because if there is something mixed up Plate heat exchangers can cause clogging and eventually cracking.

Comparison of differences between Standard brazed plate heat exchanger vs Alfa Laval AC-series.

Alfa Laval AC – Alfa Chill

Refrigerant distribution system

Standard brazed plate heat exchanger

Some channels receive more liquid refrigerant than others. This results in reduced performance.

Alfa Laval AC-series

The fluid distribution system creates an even fluid pattern and maximized performance
