ASME SA179 Aluminium 1060 Embedded Fin Tube G-Type Fin for Condenser, Cooling System

Advantages of G-fin tube:

1. Strong heat transfer capacity: compared with the optical tube, the heat transfer area can be increased by 2-30 times, and the heat transfer coefficient can be increased by 1-2 times. Usually in the conversion of thermal power equipment, the area of heat, in life a lot of equipment are used. Intelligent image design, to achieve better protection of the environment in life.

2. Compact structure: With the increase of heat transfer area per unit volume, the heat transfer capacity is enhanced. Compared with the rain tube with the same heat load, the G fin tube heat exchanger has fewer tubes and the barrel diameter or height can be reduced, so the structure is compact and easy to arrange.

3. can be more effective and more reasonable use of materials: not only because of the compact structure, reduce the amount of materials, but also according to the heat transfer and process requirements of flexible choice of materials, such as the use of different materials Mosaic or welding.

4. When heating the medium, compared with the light tube, the wall temperature of the G-fin tube under the same heat load is reduced, which is conducive to reducing the high temperature corrosion and overtemperature damage of the metal surface. Regardless of whether the medium is heated or cooled, the heat transfer temperature difference is smaller than that of the light tube, which is conducive to reducing the scale on the outer surface of the tube. Another important reason for the reduction of scale is that G-finned tubes do not form a uniform overall scale layer along the circumference or axis as light tubes do. Under the action of expansion and contraction, the scale formed along the surface of the fin and pipe will break at the root of the fin, prompting the scale to fall off by itself.

5. For phase change heat transfer, the heat transfer coefficient or critical heat flux can be calculated.
The disadvantages of G-fin tubes are high cost and high flow resistance.
For example, due to the complexity of the process, the cost of the air cooler accounts for 50-60% of the cost of the equipment; Large resistance results in large power consumption. But if the shape is right, power consumption can be reduced, which is cost-effective compared to the benefits of enhanced heat transfer.
