Finned Heat Exchanger For Gas To Liquid Heat Exchange

(1) High heat transfer efficiency, due to the disturbance of the fluid by the fins, the boundary layer continuously ruptures, resulting in a large heat transfer coefficient; Meanwhile, due to the thin partition and fins, which have high thermal conductivity, plate fin heat exchangers can achieve high efficiency. Price of finned heat exchangers.

(2) Compact, due to the extended secondary surface of the plate fin heat exchanger, its specific surface area can reach 1000 ㎡/m3.

(3) Lightweight, due to its compact and mostly made of aluminum alloy, steel, copper, composite materials, etc. have also been mass-produced.

(4) The plate fin heat exchanger has strong adaptability and is suitable for heat transfer between gas, gas liquid, liquid liquid, and various fluids, as well as phase change heat transfer that undergoes changes in concentration. The arrangement and combination of flow channels can adapt to different heat transfer conditions such as counter flow, cross flow, multi stream flow, and multi pass flow. The combination of series connection, parallel connection, and series parallel connection between units can meet the heat exchange needs of large-scale equipment. In industry, it can be standardized and mass-produced to reduce costs, and interchangeability can be expanded through modular combination.

(5) The manufacturing process requires strict requirements and is complex.

(6) Easy to block, not corrosion-resistant, and difficult to clean and maintain, so it can only be used in situations where the heat exchange medium is clean, corrosion-free, not easy to scale, not easy to deposit, and not easy to block.
