WebLike your radiator at home, a car radiator contains a network of pipes running from the so-called top tank to the bottom tank. Unlike your radiator at home, though, the one in a car is a dense mass of thin aluminium layers in a honeycomb structure that surrounds the pipes carrying the coolant. The heat passes from the coolant to the aluminium.

WebRadiant heat transfer rate from a black body to its surroundings can be expressed by the following equation. Q ˙ = σ A T 4 (2-12) where: Two black bodies that radiate toward each other have a net heat flux between them. The net flow rate of heat between them is given by an adaptation of Equation 2-12.
