Aluminum corrosion-resistant fin material 6815 fin width 26.5 mm for micro-channel condenser
Product Description:
The design of Insert fin
This product adopts a new type of fin related to the technical field of heat exchangers, especially a parallel flow heat exchanger for microchannels. It includes fins and a substrate, characterized by the substrate being distributed in a sine wave extension. The substrate is equipped with two sets of louvers on the sine wave side wall, which are composed of several strips. Each set of louvers is tilted along the surface of both sides of the substrate and forms an angle with the surface of the side wall, The two sets of louvers on the same side wall form a symmetrical angle with the surface of the substrate. The louvers on adjacent side walls fold and overlap with each other along the sine wave extension direction, and the airflow direction is perpendicular to the extension direction of the substrate. This can make the airflow flow in the fins with moderate resistance, effective airflow, optimal effective heat transfer area, good heat transfer efficiency, easy production, low cost, and good mechanical performance.
Production Process:
Fin stamping →aggregate→header assembly→press forming→degrease spray (FLUX) drying,
Preheating→(NB) →brazing→ forced air cooling →plastic connection pipe welding →helium leak detection→ultrasonic cleaning→coating→ drying →sheet metal assembly →final inspection→packaging
Features:
YUNNENG designs and manufactures high-performance microchannel condenser insert fins displaying a number of advantages over traditional condenser fin designs, the key of those are:
Conformity and reliability
Fings are very easy to break and deform after stamping and forming, and the automatic assembly machine(Manufacturing Equipment-Filling and molding machine) is used to avoid wing deformation and inconsistent wing spacing.
Frost work condition
With better frosting performance, 30% better than the traditional microchannel performance.
Passivation + hydrophilic coating
