u003cbru003e In order to avoid engine overheating and ensure the cooling effect, the parts around the combustion chamber (cylinder liner, cylinder head, valve, etc.) must be properly cooled. The automobile cooling system is composed of radiator, thermostat, water pump, cylinder water channel, cylinder head water channel, fan and so on. The radiator is responsible for the cooling of the circulating water. Its water pipes and radiating fins are mostly made of aluminum. The aluminum water pipes are made of flat shape, the radiating fins are corrugated, and the heat dissipation performance is squarely viewed. It is possible to achieve lower wind resistance and higher cooling efficiency.

u003cbru003e 1. The radiator belongs to the automobile cooling system. The radiator in the engine water cooling system is composed of three parts: the water inlet chamber, the water outlet chamber, the main plate and the radiator core. The coolant acts in the radiator core, and the air passes through the radiator core. The hot coolant becomes cold by dissipating heat to the air, and the cold air heats up by receiving the heat from the coolant, so the radiator is a heat exchanger.

When the water temperature rises, the cooling water in the car radiator expands and the pressure of water vapor is increased, and the steam valve is knocked out; when the water temperature drops, the pressure drops and the air valve opens, and the outside air will be removed from the public The air holes enter the radiator to ensure that the pressure in the radiator remains unchanged.

u003cbru003e 3. The radiator is the main part of the cooling system, the 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 radiator has two main components, the radiator fin composed of small flat tubes, and the overflow tank (on the upper, bottom, or both sides of the radiator fin).
