Finned Tube Heat Exchangers

Introduction

Finned Tube Heat Exchangers are a type of device that enhances gas-side heat transfer by expanding the outer surface of the tube (by adding fins), achieving efficient gas-liquid or gas-vapor heat exchange. They are not only suitable for single-finned tube heat exchangers, but are also widely used in industries such as power, chemical, petrochemical, air conditioning, and refrigeration. Our company can provide you with the best solution based on your specific application and specifications.

Flexible Structure and Materials

1. Base Pipe: Copper, aluminum, carbon steel, stainless steel, or bimetallic composite pipe

2. Fins: Aluminum, copper, steel; available in wound (L, LL, KL), rolled, sleeved, welded, and integral extrusion types, with various geometries including straight, corrugated, windowed, serrated, and porous.

3. Common pipe diameters: 3/8", 1/2", 5 mm, 7 mm; number of rows, fin height, density, and number of loops can all be customized.

Features

1. High Heat Transfer Efficiency: Fins significantly increase the heat transfer area, especially optimizing gas-side heat transfer, resulting in superior overall performance.

2. Compact Structure: Provides a large heat exchange area within a unit volume, saving installation space.

3. High Economic Efficiency: Under the premise of achieving the same heat exchange capacity, it is generally more economical in terms of materials, volume, and cost compared to pure bare tube heat exchangers.

4. Flexible Design: Fin parameters (height, spacing, thickness), number of tube rows, and loop design can be precisely customized according to air resistance and heat exchange capacity.

5. Reliable and Durable: Robust structure, low maintenance requirements, and long service life.

Applications

Finned tube heat exchangers are widely used in power, chemical, petrochemical, air conditioning engineering and refrigeration engineering, such as surface air coolers, air heaters, and fan coils used in air conditioning engineering. The air cooler evaporator and frost-free refrigerator evaporator used in refrigeration engineering are not only suitable for the flow of single-phase fluid, but also have great value for phase change heat.

Most of the fin-tube heat exchangers used for clean gas use a new and efficient fin surface structure, which has achieved a significant heat transfer enhancement effect.

Advantage

Our company has Product quality ensured by the modern equipments and managements:

International advanced large-sized equipment of pulse, plasma arc welder, auto polishing machines, modern labs, various testing equipments; ASME and ISO9001 certified.

Installation and Maintenance

Installation: Ensure uniform air distribution for air-cooled models; avoid excessive vibration; maintain appropriate tube spacing for easy cleaning.

Maintenance: Regularly clean the fin surface (use pressurized air/water to remove dust); check for loose connections between fins and tubes; replace damaged tubes promptly; apply anti-corrosion coating according to operating conditions.
