exothermic heat by radiation in physics
The hot water is in contact with the metal casing of the radiator, so that metal radiator takes some heat from the water. The heat then passes from the inside metal of radiator to the outside metal of the radiator through convection. The outside metal of the radiator then passes it to the air that is blowing by it outside.
To transfer heat from one place to another. In a car it moves engine heat to the outside air. In a house heating system it moves heat into the living space.
A radiator gives off heat not prevents it.
A white surface is a good radiator of heat.
a radiator that provides heat and cooling
As coolant cycles through the engine, it absorbs heat from the engine, after which, it continues through the cooling system back to the radiator. As the coolant passes through the radiator, the heat is exchanged to the ambient air by way of airflow through the radiator fins (this is why it's important not to bend the radiator fins).
Radiator is a device to cool the heat engin using water as a coolent
heat
In your car, the radiator transfers its heat to the surroundings - the air. [Strictly, this is conduction, but don't quibble. This is mechanic talk.] In your room, the radiator does radiate heat into the room.
