The working temperature and gas flow device of the brazed aluminum plate fin heat exchanger

- Nov 16, 2017 -

Brazed aluminum plate fin heat exchanger is a compact, high efficiency, low temperature resistance heat transfer equipment, which has the characteristics of complex design theory and high precision of fin forming and brazing all-in-one. Brazed aluminum plate fin heat exchanger is especially suitable for multi-stream, and the heat transfer process has the heat transfer requirements of the phase change.

The brazed aluminum plate fin heat exchanger can be used in the separation of the gas flow device, mainly using the liquefaction and distillation method to separate the steam body of the raw material into its various components. When the equipment is running, the gas and waste gas are heated by heat transfer with the raw gas. Condensers and evaporators are installed in the dephlegmation tower, and coolers are often used. And the plate fin heat exchanger is very suitable for these aspects and many other occasions.

The brazed aluminum plate fin heat exchanger is mainly used in the process of low temperature air separation equipment, liquefaction plant, tail gas treatment, petrochemical products production and natural gas processing. The highest working pressure of the equipment in the running process can exceed 100 barg.

Brazed aluminum plate fin heat exchanger can instinctively adapt to the whole vacuum design environment. High - pressure environments require manufacturer size limits and thicker components, so that a single heat exchanger can have pressure from the smallest to the maximum of more than 12 fluids.

In the working process, the highest working temperature of the brazed aluminum plate fin heat exchanger is 65 ℃. The 5083 aluminum alloy pipeline can be used in the production process. Under the lower pressure, the design temperature can be as high as + 204 ℃. The design temperature more than 65 ℃ is common. The minimum design temperature is - 269 ℃.
