The Five Advantages Of Aluminum Plate Fin Heat Exchanger
1. Good economy
Due to its relatively compact structure and small size, the aluminum plate fin heat exchanger is made of aluminum alloy, which has a light weight and low manufacturing cost.
2. Light and firm
Because of plate-fin heat exchanger fin is thin, generally 0.2 -- 0.3 mm, the compact structure, small volume of heat exchanger, heat exchanger generally all made of aluminum, and very light in weight, and fin is a main heat exchange surface and two partition support, so the strength is very high. For example, a plate-fin heat exchanger made from a flat screen with a thickness of 0.7 mm and a thickness of 0.2mm can withstand the load of the pressure of 4MPa.
3. Compact structure
The heat transfer area within the unit volume can generally reach 1500 -- 2500m2 / m3, which can reach up to 5000m2 / m3. In terms of the heat transfer area of the unit volume, the plate-fin heat exchanger is 2 -- 5 times that of finned tube heat exchanger.
4. High heat transfer efficiency
Because of the disturbance of the convection of the fin, the boundary layer is constantly breaking up, so it has a large coefficient of heat exchange. At the same time of material (aluminum) has high thermal conductivity as well as the smaller equivalent diameter, so the plate-fin heat exchanger can achieve high efficiency, the air force to flow heat transfer coefficient of up to 350 ℃, w/m2.
5. Adaptable
Aluminum plate-fin heat exchanger can be used for the gas - gas, gas - liquid, liquid - liquid, the heat exchange between the can also be used for the existence of phase transition occasion such as condensation and evaporation, this kind of heat exchanger in the upstream, downstream and cross-flow flow.
