A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface for heat transfer to air that is forced past them, by a fan, thereby heating the passenger compartment.

Famous quotes containing the word core:
“For books are more than books, they are the life
The very heart and core of ages past,
The reason why men lived and worked and died,
The essence and quintessence of their lives.”
—Amy Lowell (1874–1925)
