Title: Innovations of Chih-Liang Chien

Introduction

Chih-Liang Chien is a notable inventor based in New Taipei, Taiwan. He has made significant contributions to the field of aerosol technology, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest inventions is the "Corona-wire unipolar aerosol charger." This invention focuses on reducing charged particle loss by radially introducing sheath air from a porous wall. The design includes a charging chamber, aerosol inlet channels, a corona wire, and both sheath air inlet and outlet openings. The innovation ensures that charged particles do not deposit on the wall surface of the charger, provided that the radial velocity of the introduced sheath air is comparable to the electrostatic velocity of the charged particles. Additionally, the dilution effect of charged particles is minimized by redirecting excess clean air outside the charger.

Another significant patent is the "Tube bundle heat exchanger of constant temperature gradient for thermophoretic deposition of aerosol particles." This invention features a housing with an internal chamber containing staggered cold and hot tubes. The arrangement allows low and high-temperature fluids to flow through the respective tubes. As exhaust gas passes through the chamber, the temperature gradient between the tubes causes aerosol particles suspended in the gas to deposit on the cold tubes, effectively treating the exhaust gas. This design enhances the overall removal efficiency of particles.
