How to make choice of the plate material for Heat Exchanger Plates

Heat Exchanger Plates

1. The working principle of the plate heat exchanger is through the heat transfer mechanism. According to the laws of thermodynamics, heat is always spontaneously transferred from high-temperature objects to low-temperature objects. Two fluids with different temperatures flow in a space separated by the wall. Through wall heat conduction and fluid convection on the wall surface, heat exchange between the two fluids is promoted. Under the same flow resistance and pump power consumption, its heat transfer coefficient is about three times higher than that of a shell-and-tube heat exchanger. It is a key, efficient and new equipment for rational utilization of effective resources, conservation and development of new energy.

2.When there is a temperature difference between two fluids, heat must be transferred. During the forced convection heat transfer process between the two fluids with a temperature difference, the heat exchange plates of the plate heat exchanger are metal with a certain corrugated shape. The surface of the plate is optimized with a corrugated wave structure to achieve a heat exchange rate of more than 92%. A thin rectangular channel is formed between each plate. Even if the fluid flow rate is below the Reynolds number, the movement of the fluid between the plates is three-dimensional. Movement causes the fluid to form violent turbulence, reducing boundary layer thermal resistance and enhancing heat transfer efficiency.

3. The working principle of the plate heat exchanger enables the plate heat exchanger to have the characteristics of high heat transfer efficiency, small footprint, wide application range, and flexible operation.

The plate materials used in plate heat exchangers correspond to the exchange media are:

1. Stainless Steel: Compatible with water, oil, and many chemicals.
2. Titanium: Suitable for corrosive media like seawater and acids.
3. Nickel Alloys (such as Inconel or Hastelloy): Resistant to high temperatures and corrosive fluids.
4. Carbon Steel: Commonly used for water-to-water heat exchange.
5. Copper Alloys: Suitable for high thermal conductivity applications.

These materials are chosen based on the compatibility with the specific exchange media to ensure efficient heat transfer and durability in plate heat exchangers.
