What is the role of the Lexus radiator fan?

With the development of society, the parts inside the car are also constantly updated. Especially the cooling fan on the car. So everyone knows what the role of the cooling fan is? And what is the working principle?

Car cooling fan role introduction: role

It is mainly used for engine heat dissipation and coolant heat dissipation to ensure that the engine does not cause high temperature and malfunction.

Automotive engines must be moderately cooled in a high-temperature operating environment to maintain their optimum operating temperature to meet the engine's good performance, durability, and exhaust emissions requirements. The engine cooling system plays a key role here. It mainly includes components such as cooling fan, water tank and thermostat.

(1) The radiator belongs to the automobile cooling system. The radiator in the engine water cooling system consists of three parts: the inlet chamber, the outlet chamber, the main piece and the radiator core. The coolant is inside the radiator core and the air passes through the radiator core. The hot coolant is cooled by heat dissipation to the air, and the cold air is heated by the heat dissipated by the coolant, so the radiator is a heat exchanger.

(2) The radiator serves as both a water storage and a heat dissipation function, and an air vapor valve is arranged on the radiator cover of the automobile, and a common air hole is connected to the atmosphere. When the water temperature rises, the cooling water in the radiator of the car expands and the water vapor pressure rises, the steam valve is smothered; when the water temperature drops, the pressure drops, the air valve opens, and the outside air will go from this public The air holes enter the heat sink to ensure that the pressure inside the heat sink does not change.

(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 heat sink has two main components, a heat sink consisting of small flat tubes, and an overflow tank (on the top, bottom or sides of the heat sink).

Introduction to the role of automotive cooling fan: principle

In order to avoid the overheating and ensure the cooling effect, the components around the combustion chamber (cylinder liner, cylinder head, valve, etc.) must be properly cooled. The car cooling system is composed of a radiator, a thermostat, a water pump, a cylinder water channel, a cylinder head water channel, and a fan. The radiator is responsible for the cooling of the circulating water. The water pipe and the heat sink are mostly made of aluminum. The aluminum pipe is made into a flat shape, the heat sink is corrugated, and the heat dissipation performance is applied. The standard of the installation is perpendicular to the standard policy of the air. It is possible to achieve a small wind resistance and a high cooling efficiency.

The coolant is inside the radiator core and the air passes through the radiator core. The hot coolant is cooled by heat dissipation to the air, and the cold air is heated by the heat dissipated by the coolant, so the radiator is a heat exchanger.
