How to distinguish solar energy and heat exchanger tubes

What Is a Heat Exchanger and How Does It Work?

Double tube heat exchangers, also known as shell and tube heat exchangers, are workhorses in industries demanding high-performance heat exchange. In this design, two separate tubes are employed: an inner tube through which one fluid flows and an outer tube through which the other fluid circulates.

Heat exchanger

Heat exchangers are systems that use a fluid to absorb heat from a hotter outside source without the fluid and hot source mixing together. Therefore, the fluid that entered hot, leaves cold and the initially cold fluid leaves hot. For example, water can be heated while inside a metal pipe within a furnace or boiler..
