Jan 01, 2018 · Helical coiled double-pipe heat exchangers are considered the most applicable type of heat exchangers in various industries including cooling applications because of their high performance, high heat transfer rate, and compact volume. Flow in a double-pipe heat exchanger can be co-current or counter-current . Double-pipe heat exchangers are usually used as counter-current heat exchangers and can be considered as alternatives to shell-and-tube heat exchangers.

Alfa Laval - Process shell-and-tube heat exchangersThe ProShield inlet on our double-pipe type quench exchanger does not suffer from the problems with coke growth and cracks in the Y inlet commonly found in similar quench exchangers. The highly effective cooling of the inlet and the short residence time dramatically reduce the difference in thermal expansion between the inner and the outer pipe, and the risk of fatigue cracks in the Y inlet.
A comprehensive review on double pipe heat exchangers Jan 05, 2017 · Wu et al.  Investigation on the effect of water and nanofluids in a double pipe helical heat exchanger under laminar and turbulent flow regimes. The heat transfer enhancement of the five nanofluids over tap water ranges from 0.37% to 3.43% for the constant flow velocity basis for both laminar and turbulent flows.
