The main role of the car radiator
The main function of the car radiator is to protect the engine and prevent overheating. The radiator is the main part of the cooling system, its purpose is to protect the engine from damage caused by overheating. The principle of the radiator is to use cold air to reduce the temperature of the coolant from the engine in the radiator.
The specific working principle of the radiator
The radiator conducts the heat inside the car engine to the heat sink through the heat sink inside it, and then carries the heat away through the cold air, thus keeping the temperature of the engine within the proper range. In addition, the radiator design includes a radiator plate consisting of small flat tubes and a overflow tank (usually located on the upper, bottom, or sides of the radiator plate).
Other relevant functions and importance of radiators
The windshield of the radiator is also very important in the performance car, it can provide sufficient air flow rate, ensure the heat dissipation effect of the power system, stabilize the power output, and organize the airflow direction, reduce wind resistance and reduce fuel consumption. The wind deflectors in racing cars serve a similar function, with better power output via the radiator.
A car radiator works by reducing the temperature of coolant through heat exchange. The coolant heats up as it absorbs heat in the engine and flows into the radiator core. The core of the radiator is usually composed of many thin cooling tubes and cooling fins. The cooling tubes are mostly flat and circular in section to reduce the air resistance and increase the heat transfer area. The air flows from the outside of the radiator core, the hot coolant radiates heat to the air and becomes cool, and the cold air becomes warm because it absorbs the heat of the coolant. This process reduces the temperature of the coolant, thereby achieving heat dissipation.
The structure of the automobile radiator
The automobile radiator is composed of inlet room, outlet room, main board and radiator core. The coolant heats up as it absorbs heat in the engine and then flows into the radiator core. The radiator core is usually composed of many thin cooling tubes and fins, and the cooling tubes are mostly flat and circular sections to reduce air resistance and increase the heat transfer area. The air flows from the outside of the radiator core, the hot coolant radiates heat to the air and becomes cool, and the cold air becomes warm because it absorbs the heat of the coolant. This process reduces the temperature of the coolant, thereby achieving heat dissipation.
Type of car radiator
Car radiators are generally divided into water-cooled and air-cooled two types:
Water-cooled radiators : Heat is carried away by the flow of coolant. The pump pumps the coolant into the radiator, and then uses the running wind and the operation of the fan to cool the coolant and achieve the cooling effect.
air-cooled radiator : through the flow of cold air to achieve the effect of heat dissipation. The air-cooled cooler has a dense heat sink structure in the housing, which can help conduct heat and keep the engine temperature at a low level.
