A heat exchanger is just a fancy name for the radiator. There is also a heat exchanger for the heating system in your car. This is typically located on the firewall on the passenger side of the vehicle.
Heat and humidity is drawn from the area being cooled (a room, the passenger compartment of a vehicle, etc.) and is exchanged to the refrigerant. The refrigerant gets pressurized and heated even more, then it passes through the condenser. The temperature difference causes a rapid heat exchange, as the cooler air absorbs the heat from the refrigerant in a heat exchange.
Since the question is about heat exchange, I assume it is a man made. The first form of heat exchange is cooking. The first fluid is then water.
HEAT
It is the radiation of heat.
It has heat exchange.
Too much heat.
Heat flux is the primary performance paramater in boiler performance. Heat flux can be affected by many factors espacially by boiler tube fouling ( or exchange surfaces) that will considerably reduce heat exchange.
Convection
If it does not open - vehicle will overheat rapidly - no cabin heat If it does not close - vehicle will not get to normal operating temperature and therefore no heat
Jonah is awesome and he knows it
Enthalpy-The heat added to or loss by a system at constant pressure
Agitated vessel heat exchange refers to the heat exchange that is carried by the internal coils or through the external jacket on the vessel. A recirculation loop with an external heat exchanger may be used when the coils or jacket cannot provide the surface area required.
