Definition - What does Heat Exchanger mean?
Heat Exchanger is a unit through which heat is transferred from one fluid to another. The solution in the Heat Exchanger can be separated by preventing the direct contact of the liquids. The internal combustion engine is a good example of the Heat Exchanger as it regulates the coolant through radiator coils. Parallel flow, cross flow and counter flow are the three main categories of exchangers, which are divided on the basis of flow arrangement.
Petropedia explains Heat Exchanger
The Heat Exchanger transfers heat from one place to another at different starting temperature. If the Heat Exchanger has only one phase then it is termed as Single Phase Heat Exchanger whereas if it has two phases it is termed as Two Phase Heat Exchanger. It is used as a boiler in large power plants and can also be used as a condenser in steam-driven turbines. Different exchangers have different tube diameters, axial strength, tube lengths, hoop strength and buckling strength. The exchangers are designed to enhance the surface area of the wall between two fluids.
