Manufacturing process requirements of plate-fin radiator

    With the development of society, plate-fin radiators are more and more familiar and used in petroleum, chemical, natural gas processing and other industries. The appearance of the plate-fin radiator has raised the heat transfer efficiency of the radiator to a new level. At the same time, the plate-fin radiator has the advantages of small size, light weight, and can handle more than two kinds of media. It can be said that in the past decade, the production of the plate-fin radiator in China has developed rapidly, and the design and manufacturing technology is also relatively mature. It has been widely used in the air separation, power machinery, aerospace and other industrial sectors, and some of it has been exported abroad. So what are its characteristics that can be applied by so many enterprises and manufacturers? Let's take you to know.

1）Compact, since the plate-fin radiator has an expanded secondary surface, its specific surface area can reach 1000 ㎡/m3。
2) The heat transfer efficiency is high, and the boundary layer is constantly broken due to the disturbance of the fin to the fluid, so it has a large heat transfer coefficient; At the same time, because the baffle and fins are very thin and have high thermal conductivity, the plate-fin radiator can achieve high efficiency.
3）Lightweight, because it is compact and mostly made of aluminum alloy. Now steel, copper and composite materials have also been produced in batches 。
4）Strong adaptability,板翅式散热器It is applicable to the heat transfer between gas-gas, gas-liquid, liquid-liquid and various fluids and the phase change heat transfer with the change of concentration. The arrangement and combination of flow channels can adapt to different heat transfer conditions such as countercurrent, cross-flow, multi-stream flow and multi-pass flow. The combination of series, parallel and series-parallel between units can meet the heat exchange needs of large equipment. In industry, it can be finalized and produced in batches to reduce costs and expand interchangeability through block-type combination.
5) The manufacturing process is strict and complex.
6) It is easy to block, not resistant to corrosion, and difficult to clean and repair, so it can only be used in occasions where the heat exchange medium is clean, non-corrosive, not easy to scale, not easy to deposit, and not easy to block.

    一台典型的板翅式换热器主要组成元件有翅片、隔板、封条、导流片和封头等。对于需要存放的换热器和设备，应存放在干燥通风和无污染的地方，因设备多数在低温下使用，因此必须严格防止水分和炔烃进入，以保证使用安全，否则会因温度变化而冰冻胀裂以及炔烃在内部积聚而发生爆裂。
    以上就是想要跟大家分享的一些关于板翅式散热器的资料，希望能够帮助到大家。虽然其优越的性能和成熟的技术已在各工业部门得到较广的应用，但是大家也不能放松警惕，日常使用机械工作前应该做好应有的检查以防机械故障。
