摘要
设计了一种旋转机械噪声发电及降温系统,起到了减噪和辅助降温的作用。该设计的原理是利用压电转换装置收集旋转机械噪声转换为电能输出,然后驱动半导体制冷装置降低旋转机械周围的温度,既实现了能源的二次利用又改善了工作环境。
A rotating machinery noise power generation and cooling system is designed, which plays a role of noise reduction and auxiliary cooling. The principle of the design is to use the piezoelectric conversion device to collect rotating machinery noise into electric energy output, and then drive the semiconductor refrigeration device to reduce the temperature around the rotating machinery, which not only realizes the two use of energy, but also improves the working environment.
