%X The research paper tends to review the effectiveness
of helical coil in heat exchangers (HCHE). Heat exchanger is a device used in
transferring thermal energy between two or more fluids or solid interfaces and
a fluid, in solid particulates and a fluid at different temperatures and
thermal contact. The author has concisely discussed the helical coil in heat
exchanger at different shapes and conditions and compared the HCHE with
straight tubes heat exchangers, and the factors affecting the performance and
effectiveness of the helical coil heat exchanger such as the curvature ratio,
and other heat exchangers. The author demonstrated that the HCHE provided more
excellent heat transfer performance and effectiveness than straight tubes and
other heat exchangers because of secondary flow development inside the helical
tube, and heat transfer coefficient increased with an increase in the curvature
ratio of HCHE for the same flow rates. The secondary flow and mass flow rates,

disadvantage</span><span style=\"font-family:Verdana;\">s</span><span style=\"font-family:Verdana;\"> have
also been reviewed. The authors back their findings with available theories.
Suitable fluid should be searched for high efficiency in the helical coil.
