Automotive Mixed Flow Fan with Guide Vanes on Blade Surfaces 800034

We have developed a simple and lower cost mixed air flow fan with guide vanes on the blade surfaces for use in automotive engine cooling. Through investigation of the fan performance and flow visualization, the axial and radial flow produced by this fan proved to be most suitable and efficient for engine cooling. The improved efficiency and increased air flow provided by this fan contribute to reduction of specific noise level and power consumption as compared to conventional fans. It is moreover possible to reduce the size and dimensions of the fan while maintaining its cooling performance. It is also useful for eliminating heat dwelling and high temperature problems from the exhaust pipe and carburetor in the engine room.
