How does a radiator transfer heat
WebThe radiator is a heat exchanger meant to transfer heat from the coolant through its passages so that the coolant can continue traveling through the engine. Mainly made from aluminum, radiators transfer heat from the hot coolant through tubes and as air blows with the assistance of fans, it blows across the fins of the radiator to cool the fluid. WebRadiation is the rate of heat transfer through the emission or absorption of electromagnetic waves. The rate of heat transfer depends on the surface area and the fourth power of the absolute temperature: Q t = σeAT 4 Q t = σ e A T 4, where σ = 5.67 × 10 −8 J/s ⋅ m 2 ⋅ K 4 is the Stefan-Boltzmann constant and e is the emissivity of the body.
