What is a heat exchanger?
The heat exchanger is a component that converts heat from one medium to another. It accords to the second law of thermodynamics. The heat exchanger is used in heating and cooling systems to control the temperature of enclosed space. Tubes, tube sheets, shells, and baffles are the internal parts of the heat exchanger.
To understand the work of heat exchangers, we need to know about conduction, convection, and radiation.
Conduction means passing thermal or electrical energy between materials that are connected to each other. Energy transfers low-level temperature to a high level.
