■  Heat Transfer Diagram of Typical Heat Exchanger






■  Functional Types of Heat Exchangers
    1. Exchanger 
        Heats one stream while cooling another
    2. Cooler
        Cools liquids or gases without condensation
    3. Condenser
        Cools a vapor to its dew point in order to extract condensate from it
    4. Chiler
        Uses refrigerants to cool a stream below the standard temperature of available cooling water stream.
    5. Heater
        Heats process stream with no appreciable vaporization (Often use steam as heating medium)
    6. Reboiler
        Reboils the bottom stream of a fractionating tower prior to its return to the tower
    7. Steam Generator
        Uses process liquids or gases to produce steam (Usually from boiler feed water)
    8. Vaporizer
        Vaporizes part of a process stream (Also called an Evaporator)
