Do You Know What Are the Points of the Plate Heat Exchanger?

The plate heat exchanger is a new type of high-efficiency heat exchanger made of metal plates stacked with certain corrugated shapes. The structure includes gaskets, compression plates, and frames, the plates are sealed and guided by sealing gaskets, separating the cold and hot two fluid channels. Different media flow through the respective channels and exchange heat with the separated plates to achieve the required temperature. Next, we will introduce the advantages of the plate heat exchanger.

Here is the content list:

• High heat transfer coefficient

• Fouling thermal resistance is small

• Fouling is lighter

• Flexible assembly

High heat transfer coefficient

There are three main types of corrugated surface plates: protruding plates, transverse plates, and herringbone plates. The herringbone type is the most used in the heating field. The low flow rate that is 0.15~0.85m/s can stimulate a turbulent flow state, and on both sides of the plate heat transfer coefficient is very high, as shown by the data, the plate heat exchanger heat transfer coefficient is 2~4 times the column tube type, and at this time the pressure drop is similar.

Fouling thermal resistance is small

Plate heat exchanger plate is generally used stainless steel plate or titanium plate and other alloy steel plate, the general plate thickness meter for 0.8 ~ 0.9mm, due to the thin plate wall, so that the thermal resistance of the plate wall is reduced. Of course, also with the plate wall occurs strongly turbulent flow, resulting in heat exchanger surface fouling thermal resistance is small. According to the U.S. Plate Heat Exchanger Manufacturing Association (TEMA) standard plate heat exchanger fouling thermal resistance, when the same medium, according to the tube heat exchanger within the fouling thermal resistance l / 5 selected.

Fouling is lighter

This is because the plate has a higher end flow, resulting in dirt mixed with debris suspended, when the plate as a heat transfer surface is very smooth, even if the dirt deposited hanging on the plate because there is no dead space, the plate surface is not easy to corrode when turbulence helps itself to wash, flush attached to the plate dirt, play a stripping effect. At the same time between the plate flow, space is small, so the media stagnation is less, and the plate heat exchanger cleaning up is simple and convenient.

Flexible assembly

According to different loads, the number of plates in circulation and the number of courses can be combined, so the plate assembly is flexible. If the use of an intermediate connecting plate or intermediate partition is installed on a pedestal several heat exchangers, running different loads, which can reduce the system in the pipeline, valve fittings, and other equipment, to reduce the cost of the project, reduce the footprint are beneficial.

These are the advantages of the plate heat exchanger. This is the reason why plate heat exchangers are currently the most common heat exchangers on the market. If you need to buy a heat exchanger recently, you can pay attention to Shanghai Jiangxing Chemical Equipment Co.Ltd. The company produces a variety of heat exchangers, and you can definitely pick the one that best meets your needs.
