Heat Transfer Performance Air Conditioning Condenser Louvered Fins

Product description:
The function of Louvered fins
In heat exchangers, the fins themselves play a critical role. They
provide the extended surface area needed to achieve effective heat
transfer between a gas on the finside and a fluid on the tubeside.
Fins are typically made from aluminum, copper, or steel alloys. In
order to increase the heat transfer effectiveness of the fins they
can be configured in a variety of different shapes, known as
enhancements.
The concept behind all fin enhancements is to improve heat transfer
performance via air turbulence and increased surface area, but they
all differ in efficacy with regard to a few important
considerations.
When weighing fin enhancements, it may be helpful to think of them
as part of a spectrum. Like many of the rules of physics, there are
tradeoffs, so we’ve developed an array of these enhancements.
Features:
Common louvered fins
Common louvered fins have a common orientation of notches that are
designed to raise air turbidity unidirectionally. Increasing the
severity of the louver angles improves heat transmission efficacy
up to a point, after which the effectiveness begins to decline.
The directional nature of louvered fins is an intriguing feature to
be aware of. The orientations of the louvers must be accounted for,
since poor directionality will steal performance rather than boost
it, similar to shark skin, where touch in one direction is smooth
and contact in the opposite direction is coarse and harsh.
Excellent heat transfer
Ability to foul/clean: Poor
Moderate durability
Authentic louver fins
A simpler geometry, improved heat dissipation, and a low pressure
drop should all be considered while designing a compact heat sink.
With this goal in mind, YUNNENG's original louver fins come in a
variety of fin types to accommodate varying heat transfer.
