What is a tubular heat exchanger?

A heat exchanger is designed for heat transfer between two fluids or between a solid and a fluid in motion. It is a fundamental element in a heating or cooling system, as well as in energy production and chemical processes.

Regarding its tubular variety – as there are several types of heat exchangers on the market – which can be made of stainless steel or titanium, the separation of fluids occurs in the wall of a cylindrical tube (one of the fluids circulates through an inner tube, while the other does so through an outer tube).
