Automobile wind deflector use significance
With the development of automobile technology and highway, the vehicle speed increasing, while the car is moving and air interaction aerodynamic resistance is more and more obvious, it affects the economy, power and stability of the automobile in the very great degree. In recent years, the rapid development of numerical simulation of vehicle aerodynamics, and through the optimization of aerodynamic performance on it, to reduce air resistance coefficient, improve fuel economy, can generate considerable economic benefits. Carriage body of the van was higher than that of the cab, when the van when runs at high speed, the air above the cab had closed the front above the site, resulting in a large detachment from the car top front edge, numerical air resistance increases because of the Department of.
If the installation of a diversion device in the cab top, streamline transition between the cab and the carriage, to guide the driver cab air and car body surface "convergence", the air flow along the closed carriage top very near the surface, thereby reducing the air resistance coefficient, so, van installation the dome is more necessary.Using the dome, made a contribution to the green logistics, to put forward new ideas and solutions to solve the transportation problem of energy saving and emission reduction.
