UVC Air Sterilizer Serpentine Flow Path

Instead of using turbulent flow to enhance pathogen exposure, the patent inverts the approach by using laminar flow with extended residence time. The serpentine flow path and parallel plate geometry ensure that air moves in an orderly manner, allowing UVC photons to effectively sterilize pathogens without relying on turbulence. This inversion resolves the contradiction by achieving sterilization through controlled laminar flow rather than chaotic turbulent mixing.

The patent transitions from a conventional single-dimension vertical flow chamber to a two-dimensional serpentine flow path between parallel plates. This dimensional change extends the radiation path length without increasing chamber volume, allowing UVC photons to expose pathogens more effectively while maintaining laminar flow conditions and reducing energy loss through unnecessary reflections.

The patent employs a serpentine flow path between parallel plates that effectively uses two-dimensional space within a compact volume. The air flow follows a winding path that maximizes the UVC radiation exposure distance without increasing the overall chamber dimensions, thereby maintaining both compactness and high air flow rate capability.

The serpentine flow path introduces curvature to the air flow trajectory, forcing air to follow a winding route between the parallel plates. This curved path extends the residence time and radiation path length within a compact chamber, enabling high air flow rates while maintaining effective UVC sterilization.

Instead of relying on turbulence to ensure uniform pathogen exposure, the patent inverts the approach by designing a laminar flow system where uniform velocity distribution is achieved through the serpentine geometry and parallel plate configuration. This allows high air flow rates to be maintained while ensuring consistent UVC dosing across all air streams.

The patent applies local quality control by designing the flow distribution at the inlet to ensure uniform velocity profiles across the parallel plates. The serpentine geometry and inlet configuration are specifically engineered to create consistent flow conditions in different regions of the chamber, ensuring uniform UVC dose distribution throughout the entire air stream at high flow rates.

The patent inverts the conventional approach by eliminating intentional turbulence and using laminar flow instead. The serpentine flow path between parallel plates achieves effective pathogen exposure through extended residence time and controlled flow geometry rather than through kinetic energy dissipation in turbulent eddies, thereby maintaining high aerodynamic efficiency.

Instead of accepting kinetic energy loss from turbulence as an unavoidable consequence of enhanced mixing, the patent converts the situation by using the pressure gradient in the serpentine flow path to drive laminar flow that achieves effective sterilization without energy-wasting turbulence. The controlled flow geometry transforms what would be harmful energy dissipation into useful extended residence time for UVC exposure.
