摘要

Integrated Noise & Dust Reduction (iNDr) is an advanced proprietary cooling system with the two unique functions of noise reduction and dust removal. It is installed in an ultra-low-noise hydraulic excavator launched for the first time in 2007. With its extremely low noise and dust-proof performance, it is used preferentially at many sites. Rather than becoming obsolete, it has gained in popularity, thanks to its performance. Environmental regulations are becoming increasingly stringent, and the constraints on equipment have become increasingly severe in connection with the development of smaller models: for example, the addition of a new function, mixing cooling exhaust and engine exhaust, is now required. Due to these circumstances, design tools based on fundamental theories, which allow more efficient study, are being utilized to evolve the iNDr into a "crossover duct" with a new structure, while maintaining its extremely low-noise performance.
