The structure function and working principle of automobile radiator

Release Time:2024-04-07

For me, the car is the best choice for our daily travel, because the car is fast and comfortable, so that we have a good experience. With a car, we can skip the subway to catch the bus! So do you guys know anything about cars? Xiaobian here to introduce you to the car radiator.

1. Structure

The automobile radiator is composed of three parts: inlet chamber, outlet chamber and radiator core. The coolant flows inside the radiator core and the air passes outside the radiator. The hot coolant cools as it dissipates heat to the air, while the cold air heats up by absorbing the heat emitted by the coolant.



2. Function

When you start a car, the heat generated by the engine is enough to destroy the car itself. So a cooling system is installed on the car to protect it from damage and keep the engine in the proper temperature range. The radiator is the main part of the cooling system 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.


3, the working principle of car radiator

The engine generally uses the internal combustion engine, which does work through the heat energy generated by combustion. However, the effective power is only 30% to 40% of the total energy of the fuel, and the remaining energy is lost as exhaust heat loss and mechanical friction heat loss. In particular, in order to maintain the appropriate temperature of the cylinder, cylinder head, intake and exhaust valves, it is necessary to cool the various parts of the internal combustion engine, so that the loss of heat energy as a coolant is also lost. Radiator is the use of coolant loss of heat energy to work, in order to ensure the appropriate temperature of the internal combustion engine, cooling water loss of heat energy is indispensable. Generally rely on the engine driven by the pump to make the cooling water in the engine in various parts of the forced circulation, the coolant absorbs the heat generated by the engine and distributes it to the air device is the radiator.
