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.
