Performance characteristics of U-shaped tube heat exchanger:

(1) Advantages

Performance characteristics of plate-fin heat exchanger:

(1) The heat transfer efficiency is high. Due to the continuous rupture of the boundary layer due to the disturbance of the fins to the fluid, it has a large heat transfer coefficient; at the same time, because the partitions and fins are very thin and have high thermal conductivity, the plate-rib type The heat exchanger can achieve high efficiency.
(2) Compact, because the plate-rib heat exchanger has an extended secondary surface, its specific surface area can reach 1000 m2/m3.
(3) Lightweight, because it is compact and mostly made of aluminum alloy. Now steel, copper, composite materials, etc. have also been mass-produced.
(4) The adaptability is strong, and the plate-rib heat exchanger can be applied to: heat exchange between gas-gas, gas-liquid, liquid-liquid, various fluids, and phase-change heat with changes in state. Through the arrangement and combination of runners, it can be adapted to different heat exchange conditions such as counter-flow, cross-flow, multi-stream, multi-pass flow. Through the combination of series, parallel, series and parallel between units, the heat exchange needs of large equipment can be met. Industrially, it can be shaped and mass-produced to reduce costs, and interchangeability can be expanded through modular combination.
(5) The manufacturing process is strict and the process is complicated.
(6) It is easy to be blocked, 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.
