Falling-film Heat Exchanger

Advantages of Falling Film Heat Exchangers:
1.High Heat Transfer Efficiency:
Falling film heat exchangers utilize the flow of a thin liquid film on the walls of tubes or plates, significantly enhancing the heat transfer coefficient. The thermal resistance of the thin liquid film layer is relatively low, allowing for efficient heat transfer.
2.Operation at Low Temperature Differences:
Due to their high heat transfer efficiency, falling film heat exchangers can operate at lower temperature differences. This is particularly important for processes that require precise temperature control.
3.Suitable for High-Viscosity Fluids:
Falling film heat exchangers can handle high-viscosity fluids, as the thin film flow reduces liquid stagnation and accumulation, improving heat transfer performance.
4.Low Energy Consumption:
Thanks to their efficient heat transfer performance, falling film heat exchangers require less thermal energy for the same heat transfer task, reducing energy consumption.
5.Suitable for High Evaporation Rate Processes:
In evaporation and concentration processes, falling film heat exchangers can handle higher evaporation rates. Additionally, due to the characteristics of the liquid film, they can effectively prevent scaling and fouling.
6.Compact Structure:
Falling film heat exchangers are typically designed to be compact, occupying less floor space, making them suitable for installations with space constraints.
7.Easy Maintenance and Cleaning:
Due to their simple structure, falling film heat exchangers are generally easy to disassemble, clean, and maintain, reducing operational and maintenance costs.
8.Wide Range of Applications:
Falling film heat exchangers are suitable for various industrial fields, including chemical, pharmaceutical, food and beverage, refrigeration, and air conditioning.
