Plate-fin heat exchanger consists of a series of metal plates and metal fins arranged in parallel. As the fluid passes through the plate-fin heat exchanger, the heat is transferred through the contact surfaces of the metal plates and fins. This design increases the heat transfer area and improves heat transfer efficiency.
Applications of plate-fin heat exchanger
- Air separation class placement reversible heat exchanger, condensing evaporator, liquefier liquid nitrogen and liquid air supercooler;
- Petrochemical liquefaction of natural gas, separation devices, and ammonia industry gradually gained application;
- Power machinery internal combustion locomotive radiator, automobile radiator, excavator circulating oil cooler and compressor air cooler, oil cooler and so on.
Plate-fin heat exchanger and air separator
In the air separation device, the role of plate-fin heat exchanger is to realize the cooling and heat exchange. Air separation unit is usually used to separate and purify oxygen, nitrogen and other components in the air. In this process, the gas needs to be cooled and heated to realize the purpose of separation and purification.
The plate-fin heat exchanger plays an important role in air separation units. It can cool the gas by flowing the cooling medium (e.g., water) through the plate-fin heat exchanger to remove the heat from the air. At the same time, the plate-fin heat exchanger can also realize the heating of the gas by transferring the heat to the air through the flow of hot medium (such as steam) through the plate-fin heat exchanger.
Through the cooling and heating effect of the plate-fin heat exchanger, the air separation unit can realize the temperature control of the gas to meet different separation and purification requirements. At the same time, plate-fin heat exchanger also has the advantages of compact structure and high heat transfer efficiency, which is suitable for the application scenario of air separation device that requires high heat transfer efficiency.
