High Heat Transfer Performance Condensing Louvers Specification
21*21.65mm Anticorrosive Aluminum
Product description:
The function of the window fin
The fins provide the additional surface area needed to efficiently
transfer heat from the fluid tube side to the gas on the fin side.
It plays a vital role in the heat exchanger itself.
Finned radiator is one of the most widely used heat exchangers in
gas and liquid heat exchangers. It can enhance heat transfer by
adding fins on the common tube.
All finned enhancement concepts improve heat transfer performance
through air turbulence and increased surface area, and their
effectiveness may differ in some important considerations.
The Finned-tube heat exchanger spacing and fin height mainly affect
the fin-to-fin ratio, the fin-to-tube ratio and the film heat
transfer coefficient of the media inside and outside the tube has a
great relationship. If there is a big difference in the heat
transfer coefficient between the inner and outer membrane of the
tube, the finned tube with a larger winged ratio, such as steam
heating air, should be selected. When there is a phase change on
one side of the medium, the difference of heat transfer coefficient
will be larger, such as the exchange of hot and cold air, when the
hot air down to the dew point below, you can use finned tube heat
exchanger. In the case of heat transfer between air and air without
phase change, or between water and water, bare pipes are usually
preferred. Of course, low-finned tube can also be used, because at
this time belongs to the weak heat transfer coefficient,
strengthening one of either side is a certain effect. However, the
effect of excessive wing ratio is not obvious, the best contact
area of both inside and outside the tube at the same time
strengthen, can be used threaded or grooved tube.
Features:
Common design of Louvered fin
The fin constitutes the elementary heat transfer component,
designed to enlarge the heat transfer surface area and enhance the
efficiency of heat transfer.
Common Louvre fins possess notches directed in the same way, which
are intended to augment air turbulence in a single direction.
As the angles of the louvres’ severity increase, their heat
transfer performance improves until reaching a particular point,
beyond which their efficiency starts to decline.
One noteworthy aspect of louvered fins is their directional nature
which must be taken into consideration. Similar to shark skin,
where contact in one direction is smooth and the opposite direction
is coarse and sharp, the orientation of the louvers needs to be
accurate as improper directionality can impair performance instead
of enhancing it.
Heat transfer: Excellent
Fouling/clean ability: Poor
Durability: Moderate
Original louver fins
The original louver fins have different fin types to adapt to
different heat transfer. It also allows for simplified geometry and
enhanced heat dissipation and minimum pressure drop.
