Vehicle radiators



In the field of vehicles with internal combustion engines, the radiator is connected to the engine, which pumps a liquid, usually water with antifreeze. The idea is that the fluid flow through the engine, dissipating heat, cooling the block and leading to the radiator, which in turn dissipates the heat to the atmosphere using air to a fan or blower. In short, the radiator is a heat exchanger.
The name was originally born because it was assumed that heat is exchanged by radiation, but, given the low surface having only a few cases this is true, only when its surface temperature exceeds 70 º C. Most of the time the heat is exchanged by convection or ventiloconvección.
Emission or heat dissipation of a heater depends on the temperature difference between the surface and the surrounding environment and the amount of surface contact with the atmosphere. A greater heat exchange surface and larger temperature difference, the greater the heat exchange.
