What is Double-Pipe (Hairpin) Heat Exchanger? A Double-Pipe Heat Exchanger is the simplest type of heat exchanger in its construction. It consists of one pipe mounted concentrically inside another, larger pipe. The two fluids flow through the exchanger: one through the inner pipe and the other through the annular space (the gap) between...

What is Air Cooled Heat Exchanger (ACHE / Fin-Fan)? An Air-Cooled Heat Exchanger (ACHE), often nicknamed a Fin-Fan, is a type of heat rejection device that uses ambient air as the cooling medium to cool or condense a process fluid. Instead of using water, it uses mechanical fans to force or draw air across a bundle of […]

What is Plate Heat Exchanger (PHE)? What is a Plate Heat Exchanger (PHE)? A Plate Heat Exchanger (PHE) is a type of compact heat exchanger that uses a series of thin, corrugated metal plates stacked together to transfer heat between two fluids. The plates are clamped in a frame, creating parallel flow channels for the fluids to […]

What is Shell and Tube Heat Exchanger (STHE)? What is a Shell and Tube Heat Exchanger (STHE)? A Shell and Tube Heat Exchanger (STHE) is a class of heat exchanger design and the most common type used in various industrial applications. It is built around a shell (a large pressure vessel) with a bundle of tubes inside...

How to Select Heat Exchanger Type Best For Key Advantage Key Limitation Shell and Tube High pressure/temperature, large duties Robustness & Versatility Large size, less efficient Plate (PHE) Medium pressure/temperature, high efficiency Compact & Highly Efficient Clogging, pressure limit Air Cooled (ACHE) Water conservation, moderate cooling...
