A heat exchanger is a piece of industrial equipment thattransfers heat from one surface to another. It is used as a safetydevice that is meant to keep equipment from overheating tooquickly. Heat exchangers are used in many types of machinery,including refrigeration units and natural gas processors.What a Heat Exchanger DoesThe simple process of transferring heat from one surface toanother is achieved through different heat exchanger methods. Ingeneral, a heat exchanger uses water or air to cool an engine. Anautomotive radiator works by exchanging the heat from engine fluidsto the cooler air that rushes through the engine compartment whenthe car is in operation. Some heat exchangers absorb the heatthrough conductive materials and expel it into the outside air,which cools the interior of the
