ROTATIONALFLOW GENERATION SYSTEM, AND PIPING SYSTEM, SEMICONDUCTOR FABLICATION APPRATUS, HEAT EXCHANGER

摘要

The present invention provides a rotationalflow generation device, a piping system having the same, a semiconductor manufacturing device having the same, and a heat exchanger having the same capable of preventing blocking inside a pipe. According to an aspect of the present invention, the rotationalflow generation device is installed in a pipe to generate a rotationalflow in a fluid which moves along the pipe. The rotationalflow generation device has a shaft portion and a plurality of guide wings fixed to the shaft portion.
