Heat Transfer Performance Air Conditioning Condenser Louvered Fins 21*12.7mm

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 design of Louvered fin

Common louvered fins have sets of notches made in a common orientation, which are designed to unidirectionally increase air’s turbidity. Increasing the severity of the louvers’ angles increase heat transfer performance up to a certain point, at which the effectiveness will start to decrease.

One interesting trait about louvered fins that’s important to know is their directional nature. Not unlike shark skin, where contact in one direction is smooth and the opposite direction is coarse and sharp, the directions of the louvers must be accounted for, as incorrect directionality will rob performance rather than increase it.

Heat transfer: Excellent

Fouling/clean ability: Poor

Durability: Moderate

Original louver fins

To design a compact heat sink, a simplified geometry, enhanced heat dissipation, and the minimum pressure drop should be taken into consideration. With this objective, YUNNENG‘s original louver fins have various fin type to fit the different heat transfer.
