Heat Exchanger Tubes
Heat exchanger tubes
are part of the heat exchanger device, which are an efficient
device used by many companies in engineering products such as found
in refrigeration, conditioning, and space heating and chemical
processing for transferring heat from one fluid to another through
a separating wall.
These can be classified according
to the process of heat transfer, mechanical construction and
principal material of construction. The most common type of heat
exchangers includes double pipe, shell and tube. Other special
types where the standard forms of tubular exchangers are not
satisfactory are pipe coils, spiral, plate type, fine tube and
graphite.
Heat exchanger tubes are where the transferred fluid transferred
flows. It is considered a very vital part of the device as it
facilitates in separating the two chambers and prevents the two
fluids from being in contact with one another.
Typical heat exchanger tubes are two passageways of pipe, which
snake back and forth, turning in on themselves and consists of a
number of parallel tubes enclosed in a relatively close fitting
cylindrical shell.
One fluid flows inside the heat exchanger tubes and is called
the tube side fluid while the other flows outside the tubes and is
then called shell side fluid. If none of the fluids condenses or
evaporates, then the unit will then be called in the phase of ‘heat
exchanger’. If one of the fluids, in either tube or shell
condenses, the unit is known as ‘condenser’ or simply as ‘heater’.
This varies depending on whether the primary purpose of the unit is
to condense one fluid or to heat the other.
Special types of heat exchangers also require specialized heat
exchanger tubes like that of pipe coils, spiral, plate type and
graphite. Generally, the tubes are used for cooling purposes aside
from the usual heating or condensing capacity of the device.
Standards of Tubular Exchanger Manufacturers Association (TEMA) has
set a standard and specified the design procedure and details of
constructions and as to how you could maximize the usage of your
heat exchangers. Bottom line is, once the components are properly
chosen and maintained, you can be assured of a longer lasting and
efficient device. In addition, once it is working properly, the
energy consumption is much lesser.
