Some examples of shell and tube heat exchangers

Steam condenser in a power plant: It uses shell and tube configuration to condense steam back into water.

Oil cooler in an automotive engine: Helps to cool the engine oil.

Chemical reactor heat exchanger: Used in chemical processes to control the temperature of reactants.

HVAC system heat exchanger: Facilitates heat transfer between the refrigerant and air or other fluids.

Marine engine cooling system heat exchanger: Keeps the engine at an appropriate temperature in a ship.
