Plate heat exchanger18
Plate heat exchanger is a kind of heat exchanger which is made by pressing a thin metal plate into a heat exchanger plate plate with a certain corrugated point, then stacking it, and then assembling it with frame plate and clamping bolt. The working fluid flows through the narrow and zigzag channel formed between the two plates, and the cold and hot fluid flows through the channel plates for cold and heat exchange.
Heat exchange plate: SUS304, SUS316L, SMO254, titanium, nickel, Hastelloy
Gasket: NBR, h-nbr, EPDM, food pad, Viton, silicone rubber
Frame: carbon steel, stainless steel, outsourcing stainless steel
Clamping bolt: carbon steel galvanized, stainless steel
Interface: rubber, carbon steel, stainless steel
Guide rod: carbon steel galvanized, stainless steel
The unique structure of the shunt area balances the fluid distribution.
The plate adopts a unique line and surface positioning structure, which is not easy to misplace between plates;
The fillet of plates adopts the "interlock" structure, and the plates are locked with each other.
Large angle corrugation design can improve heat transfer coefficient and reduce resistance.
The design of small angle corrugation reduces the resistance and heat transfer coefficient.
During the design and selection, according to the different working condition parameters, the corresponding plate type shall be selected reasonably to achieve the best use effect.
Double slope design of upper guide rod improves the stability of plate;
The inner side of the clamping plate adopts the lining ring structure to improve the matching accuracy;
In addition to heat transfer efficiency, herringbone corrugated plates form mesh contacts with each other in reverse direction after assembly, with good pressure resistance.
The gasket is embedded in the groove of the heat exchange plate for fixation, which is quick and convenient to insert and replace the gasket and greatly reduces the downtime;
The sealing and fixing functions are separated, and the gasket can still play a sealing role in the groove even if a part of the "buckle" that plays the fixing function fails.
● large logarithmic average temperature difference
● high heat transfer coefficient
● small floor area
● light weight and low price
● small temperature difference at the end
