Description

Wind deflector of U-shaped wind protection cover of commercial vehicle

Technical Field

The invention relates to the technical field of aerodynamics and automobile manufacturing, in particular to an air guide device of a U-shaped air protection cover of a commercial vehicle.

Background

With the constant upgrade of horsepower and emission standards of domestic commercial vehicles, the matching requirement of a heavy commercial vehicle with high horsepower on a cooling system is higher and higher, particularly for vehicles with natural gas engines of national emission standards, the matching requirement on the cooling system is higher, and as environmental regulations are upgraded, the dust problem caused by vehicle running is more and more concerned by people, the traditional wind shield structure consists of a shield body, a flexible ring and a follow-up ring, the square radiator is connected with the fan which rotates through the follow-up wind shield body and the flexible ring, the follow-up wind shield body and the flexible ring need to have smooth and transitional streamline polyhedral structures, so that the fan can uniformly suck the airflow passing through the core part of the radiator, the resistance of the fan to the airflow is reduced, the heat exchange efficiency of the radiator is improved while the air suction capacity of the fan is enhanced, and the follow-up ring can effectively reduce hot air backflow.

However, when the distance between the heat sink and the ring fan is relatively close, because the wind-protecting cover body and the flexible ring of the follow-up wind-protecting cover are designed to be flat and have abrupt transition, the wind outlet of the fan can not be fully developed when the fan is transited from the square heat sink to the fan which rotates at high speed, the wind outlet resistance of the fan is increased, the wind suction efficiency is reduced, the secondary backflow of hot wind is serious, the inlet air temperature of the heat sink is increased, the wind speed distribution on the surface of the heat sink is uneven, the heat exchange efficiency of the heat sink is reduced, and the follow-up ring of the follow-up wind-protecting cover directly. The dust raising of the fan means that the cooling fan blows to the road, the dust on the surface of the road is raised abnormally due to air movement, the commercial vehicle needs to be matched with the fan with large diameter and large air volume due to large heat productivity of the system, and the height of the fan above the ground is low, so that the dust raising is easily caused, and the treatment difficulty is high. Raise dust not only pollutes the environment, still can influence vehicle performance: dust adhesion is on the radiator surface, corrodes the fin, easily causes microbial contamination, leads to the heat-sinking capability to descend, and the serious condition causes the radiator to block up, and the cooling air can't pass through the radiator, and the engine is cooked and inside the dust can get into the motion, and the motion wearing and tearing are aggravated, lead to the fault rate to rise. Therefore, the traditional follow-up air protection cover cannot meet the requirements of matching a heavy commercial vehicle high-horsepower vehicle type cooling system and reducing dust emission hazards in the vehicle running process. Therefore, the structure of the traditional commercial vehicle fan guard structure needs to be improved, so that the heat dissipation capacity of the commercial vehicle cooling system is improved, the dust raised by a fan is reduced, and the pollution to the environment is reduced.
