Car engine cooling system with wind deflector

technical field

The utility model relates to the field of automobile parts, in particular to an automobile engine cooling system.

Background technique

The function of the automobile cooling system is to dissipate part of the heat absorbed by the heated parts of the engine in time to ensure that the engine works at the most suitable temperature. The cooling system of the engine is divided into air-cooled and water-cooled. The cooling system that uses air as the cooling medium is called an air-cooled system; the cooling system that uses cooling liquid as a cooling medium is called a water-cooled system.

Existing automobile cooling systems are all water-cooling systems, which use water pumps to increase the pressure of the coolant and force the coolant to circulate in the engine. The cooling system is mainly composed of water pumps, radiators, cooling fans, compensation water tanks, thermostats, engine blocks, water jackets in cylinder heads, and accessories.

There are two working cycles in the main cycle of the cooling system, namely "cold cycle" and "normal cycle". After the cold car is started, the engine is gradually warming up, and the temperature of the coolant is not enough to open the thermostat in the system. At this time, the coolant only goes through the water pump to carry out "cold cycle" in the engine, the purpose is to make the engine reach normal speed as soon as possible. Operating temperature. As the engine warms, the coolant temperature rises to the opening temperature of the thermostat, and the cooling cycle begins a "normal cycle". At this time, the coolant comes out of the engine, passes through the radiator at the front of the car, and after cooling, it enters the engine through the water pump.

Existing cooling systems use fans to blow air to the radiator to improve heat dissipation efficiency, but because the wind from the fan can only blow to one side of the radiator, the utilization rate of the blowing air is not high, which affects the heat dissipation efficiency.
