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
