What are the characteristics of a plate heat exchanger supplier?

　　Everything has its value. In our daily lives, there are many indispensable things and products. Similarly, in the industrial field, many mechanical equipment play their roles in different fields, and welded plate heat exchangers are no exception. Today, we, as a welded plate heat exchanger supplier, will talk about some basic characteristics of welded plate heat exchangers. If you are interested, please read on.

　　 Welded Plate Heat Exchanger Supplier A plate heat exchanger is a highly efficient heat exchanger composed of a series of metal plates with a certain corrugated shape. Long, narrow rectangular channels are formed between the plates, allowing heat exchange through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-gas heat exchange. They are characterized by high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure drop, its heat transfer coefficient is 3-5 times higher than that of a shell and tube heat exchanger, the footprint is one-third that of a shell and tube heat exchanger, and the heat recovery rate can be as high as 90%.

　　Welded Plate Heat Exchanger Supplier Introduction High heat transfer coefficient; Due to the inversion of different corrugated plates, complex flow channels are formed, causing the fluid to rotate three-dimensionally in the flow channels between the corrugated plates, and can flow at a low Reynolds number (generally Re = 50~200). Therefore, the heat transfer coefficient is high, generally considered to be 3~5 times that of shell and tube type. Large logarithmic mean temperature difference, small terminal temperature difference. In shell and tube heat exchangers, the two fluids flow in the tube side and shell side respectively. Generally, it is cross-flow, and the correction coefficient of the logarithmic mean temperature difference is small, while the plate heat exchanger is mostly parallel flow or countercurrent flow. The correction coefficient is usually around 0.95. In addition, the flow of hot and cold fluids in the plate heat exchanger is parallel to the heat transfer surface, without side flow, so the plate heat exchanger has a small temperature difference at the end, and water heat exchange can be performed. Below 1°C, while shell and tube heat exchangers are generally 5°C.

　　Welded Plate Heat Exchanger Supplier Introduction Its footprint is small. Plate heat exchangers have a compact structure, and the heat transfer area per unit volume is 2-5 times that of shell and tube heat exchangers. The heat exchanger footprint is about 1/5 to 1/8 that of a shell and tube heat exchanger. Easy to change the heat transfer area or process combination; only a few plates need to be added or removed to increase or decrease the heat transfer area; changing the plate arrangement or replacing a few plates can achieve the required process combination, adapting to new heat transfer conditions, and the heat transfer area of shell and tube heat exchangers is almost impossible to increase. Welded Plate Heat Exchanger Supplier Introduction Lightweight. The plate thickness of a plate heat exchanger is only 0.4~0.8mm, while the heat transfer tube wall thickness of a shell and tube heat exchanger is 2.0~2.5mm. The outer shell of the shell and tube type is much heavier than the frame of the plate heat exchanger. The plate heat exchanger generally weighs only about 1/5 of the shell and tube type.
