Principles and Design of Components for Energy Conversion
Before a product is created, it is designed as a model on a computer to simulate its physical functions. Bosch researchers develop simulation tools for this purpose to ensure the accuracy of computer results compared to the real world. Such tools are used in fields ranging from high frequency and flow technology to factory planning and automation.
It’s all about compact, high-performance electric power tools. That’s what the market demands. But as the power is increased while the size is reduced, heat becomes a greater problem in cordless screwdrivers, angle grinders and power drills. Researchers at Bosch are therefore engaged in computer measurements of airflows as they strive to improve cooling efficiency in such power tools. They use computer simulations to analyze otherwise inaccessible flow phenomena. This enables them to optimize cooling selectively, for instance through improved routing of the airflow or better arrangements of ventilation slots. Improved designs protect these tools from reaching or exceeding their thermal load limit. That’s how researchers can improve performance of power tools while extending their service life.
