Aluminum star-shaped fin

This study examines the effect of an aluminum star-shaped fin, placed along the axis of 5/8-inch copper tubes with a specific twist, on heat transfer in a shell-and-tube evaporator. The objective is to evaluate the enhancement of heat exchange and the reasons for using this geometric arrangement in refrigeration and HVAC applications. Fin design and configuration The star-shaped fin is formed from aluminum sheet into a multi-branch profile that fits inside a 5/8-inch copper tube and is twisted gently around the longitudinal...

Investigation of Air Flow on Fins of Fin and Tube Coils in Condensers

Introduction

When I think about what makes a condenser truly effective, I always find myself zeroing in on those intricate fin and tube coils. They’re not just passive elements; their performance directly hinges on how air moves around them—especially across the fins. Airflow and heat exchange are tightly linked here, and getting the flow right can make a world of difference in energy savings and system reliability.

The Role of Fins and Tubes

Fin and tube coils are the...

Blue fin condenser coils Vs. Gold fin condenser coils

The coils play a crucial role in the efficiency of an air conditioner. such as which material to use, which condenser coil design to employ, how much these coils cost, how long they last, etc. The longevity of an air conditioner is directly related to the quality of its condenser coils. Its job is to reduce the temperature of the refrigerant as quickly as feasible. Because it is located outside, it is susceptible to deterioration and corrosion from exposure to the...

Technical Analysis of the Advantages and Limitations of Aluminum as Fins in Fin-and-Tube Coils

Proposed Abstract:This paper presents a comprehensive examination of the reasons for using aluminum as the fin material in fin-and-tube coils. By reviewing thermal properties, heat transfer behavior, thermal conductivity, specific mass (density), corrosion resistance, formability, and manufacturing cost, we show that the combination of these characteristics makes aluminum well suited for HVAC, heating, and refrigeration applications. Additionally, the effects of fin design (fin density, thickness, and geometry), manufacturing processes (stamping, extrusion, and brazing), and performance metrics such as overall thermal...
