Finned Tubes Elliptical Type Flat Tube Heat Exchanger Helical
Finned Tube
The elliptical finned tube [1] is a heat exchange element composed
of a base tube elliptical tube and outer fins. The common ones are
elliptical rectangular finned tubes, elliptical elliptical finned
tubes, elliptical round finned tubes, spiral elliptic flat tubes,
elliptical H-shaped finned tubes and so on. Oval finned tubes are
receiving attention due to their superior performance to round
finned tubes. At present, elliptical finned tubes have been widely
used in industrial fields such as ethylene and oil refining. The
elliptical finned tube is used as a high-efficiency heat exchange
element in heat exchange equipment. The small flow resistance
outside the tube and high heat exchange efficiency make the heat
exchange equipment compact, lightweight, efficient and
miniaturized. Although many results have been achieved in their
research, there is still a lot of research work to be carried out.

Feature:
(1) Compared with round-tube finned tubes, elliptical finned tubes
are easier to achieve compact layout, which reduces the overall
volume of the entire heat exchanger, thereby reducing the
footprint.
(2) Due to the shape characteristics of the elliptical finned tube,
the air side resistance is small, and the heat transfer coefficient
between the fluids is increased; the thermal resistance in the tube
is relatively small, which increases the heat transfer of the fluid
in the tube.
(3) The heat transfer area of an elliptical finned tube is larger
than that of a round tube with the same cross-sectional area. This
is because the heat transfer periphery of the elliptical tube is
relatively long under the same cross-sectional area.
(4) The most commonly used elliptical fin tube is rectangular steel
fin, which has high strength, and the base tube is not suitable for
freezing and cracking in winter and has a long service life.
(5) Since the elliptical finned tube can be arranged more
compactly, the front row of tubes has a greater impact on the rear
row. The fin spacing of the rear row of tubes can be increased to
reduce the flow resistance outside the tube, but the number of tube
rows should not be too large. .
