Alfa Laval plate heat exchangers have the following characteristics:
Except that the plate heat exchanger has a smaller frame volume to provide a larger heat exchange area, it does not add space during maintenance. Therefore, its space volume is only about 30% of that of a tube heat exchanger, and its area is only 1/5. -1/10.
Due to the small frame and small size, the weight can be reduced by more than 50%.
3.High heat transfer coefficient
Due to the high degree of turbulence of the fluid in the plate heat exchanger, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger.
4, easy to dismantle and repair, easy to increase or decrease the heat transfer area
The non-welded structure of the plate heat exchanger makes it easy to disassemble, clean, replace, and increase or decrease plates, so it has high flexibility.
5, low degree of dirt
The smooth surface of the plate and the high turbulence of the fluid in the channel will inevitably bring about the result that the scale layer is thin, and its thermal resistance coefficient is only 1/5 of that of the tube heat exchanger.
6.Avoid mixing of two media
When fluid leaks from the gasket, it can only flow out of the drain, no mixing occurs.
7.High heat recovery rate
The high heat transfer efficiency of the counter-current method makes the temperature difference at the end only 1 ℃, and the heat recovery rate is as high as 95%.
8.Less liquid retention
80% less than tube heat exchangers.
9. Lower investment
In the case of the same material, the investment of plate heat exchanger is about 50% lower than that of tube heat exchanger.
