plate fin type heat exchanger

(1) 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 diaphragm and fin are very thin and have high thermal conductivity, the plate-fin heat exchanger can achieve high efficiency. (2) Compact, because the plate-fin heat exchanger has an extended secondary surface, so that its specific surface area can reach 1000㎡/m3. (3) Light, the reason is that compact and mostly made of aluminum alloy, and now steel, copper, composite materials have also been mass produced. (4) Strong adaptability, plate-fin heat exchanger can be applied to: gas-gas, gas-liquid, liquid-liquid, heat transfer between various fluids and phase transformation heat with state change. Through the arrangement and combination of the runner, it can adapt to different heat exchange conditions such as countercurrent, cross-flow, multi-stream and multi-stream. Through the c…
