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.
