Plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape stacked together. A thin rectangular channel is formed between various plates for heat exchange through half plates. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, and long service life. Under the same pressure loss, its Heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, covering one third of the floor area of the tubular heat exchanger, and the heat recovery rate can be as high as 90%.

A plate heat exchanger is composed of many stamped corrugated thin plates at certain intervals, sealed with gaskets around them, and overlapped and compressed with frames and compression screws. The four corner holes of the plates and gaskets form fluid distribution and collection pipes, while reasonably separating cold and hot fluids to flow in the flow channels on both sides of each plate, and conducting heat exchange through the plates.

Design characteristics of plate heat exchangers

1. Efficient and energy-saving: Its heat transfer coefficient ranges from 3000 to 4500kcal/m2 · ° C · h, which is 3-5 times higher than the thermal efficiency of shell and tube heat exchangers.

2. Compact structure: The plates of plate heat exchangers are closely arranged, and compared to other types of heat exchangers, plate heat exchangers occupy less area and space. Plate heat exchangers with the same heat exchange area are only 1/5 of shell and tube heat exchangers.

3. Easy to clean and disassemble: The plate heat exchanger clamps the clamping plates with clamping bolts, making it easy to disassemble and disassemble. It can be opened for cleaning at any time. At the same time, due to the smooth surface of the plate and high turbulence, it is not easy to scale.

4. Long service life: The plate heat exchanger is pressed with stainless steel or titanium alloy plates, which can withstand various corrosive media. The rubber pad can be replaced at will.

5. Strong adaptability: The plates of the plate heat exchanger are independent components and can be added or removed according to requirements, with various forms; Suitable for various process requirements.
