I tell u exactly why that is try this yourself take boiling water on your stove. Get it to boiling temp and hold a thermometer above the steam and take a reading notice it is much lower and then drop the thermometer into the boiling water, much higher rite???? Big difference in measuring steam temperature and direct hot water.... Just like your coolant temprature sensor it has to be submerged in coolant to get true reading ..when in fact you are over heating basically cooking your engine its just that your sensor is just not able to detect that you are cause it is reading steam temprature which in no way good for any car to be that hot especially if it is alunimum eninge it can cause major damage. and that is the best answer to your question. Thank you n have a nice day
Radiator is a device to cool the heat engin using water as a coolent
to absorb heat
With no water no heat can be transferred through the heater coils.
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.
Water is put in a radiator because it is used to transfer heat from the engine to the outside environment through the process of convection. The water absorbs heat from the engine and then circulates through the radiator to release it, helping to cool the engine and prevent it from overheating.
The method of heat transfer responsible for cooling the water and heating up the radiator as the water flows through it is convection.
Water jackets are the hollowed out spaces in the engine block and head through which the coolant flows. In water jackets, waste heat generated by the engine is picked up by the coolant. After flowing through the water jackets, water flows through the radiator. The radiator is basically a heat exchanger which, through a system of tubes and fins, transfers this waste heat from the coolant to the atmosphere. After the water is cooled in the radiator, it flows back into the water jackets of the engine to pick up more waste heat.
A Radiator.
A hot-water radiator heats a room by transferring heat from the hot water flowing through the radiator to the metal surface of the radiator. The metal then radiates this heat into the surrounding air in the room through a combination of conduction and convection. As the air near the radiator heats up, it rises, creating a natural circulation of warm air in the room.
Conduction of heat energy from the source to the water in the boiler. A pump moves the hot water to the radiator.The heat radiates out from the radiator to the air, where convection then circulates it through the room.
Water absorbs and radiates heat better than soil does.
The lower radiator hose supplies the water pump. The upper radiator hose supplies the radiator.
