Date: July 23, 2025 (publication date)

Details: The National Intellectual Property Administration disclosed that Foshan Nanhai Popula Ventilation Fan Co., Ltd. applied for a patent titled “A High-Pressure Centrifugal Fan with Three-Dimensional Flow Impeller,” with publication number CN120520802A and application date of July 2025-. The patent abstract indicates that the invention relates to the field of centrifugal fans, including a volute casing, a three-dimensional flow impeller, and a current collector. The three-dimensional flow impeller includes a rear disc and a hub. The hub penetrates the center of the rear disc and is fixedly connected to it. The rear disc is designed as a conical structure with multiple blades arrayed around it. The invention achieves greater airflow and pressure per unit volume fan by increasing the impeller speed, reducing fan volume and weight, thus improving upon the common problems of insufficient static pressure, low efficiency, and excessive weight in existing high-pressure centrifugal fans.
