Abstract
Workers in high-heat industrial environments frequently encounter thermal stress, fatigue, and dehydration, which significantly impact both productivity and safety. Existing cooling solutions such as pedestal fans, ceiling fans, and central air-cooling systems often fall short due to limited airflow reach, safety concerns from exposed blades, high energy consumption, and poor suitability for dynamic workshop layouts. To address these challenges, this study presents a novel triangular bladeless fan designed specifically for industrial settings. The proposed system integrates Air Multiplier™ technology, a triangular structural layout, and three independently orientable vents capable of delivering targeted, high-velocity airflow to multiple workers simultaneously.
The design considers ergonomic parameters including worker height, posture, and workstation distance to optimise airflow delivery to the face and upper torso—the regions most affected by heat stress. Structural stability is enhanced through a metal-based triangular frame, while an ABS plastic upper body maintains portability and durability. The fan operates at 65W and is engineered to reduce noise levels to below 65 dB, making it suitable for prolonged industrial use.
This paper outlines the conceptual design, structural principles, airflow behaviour, ergonomic considerations, and theoretical energy performance. Computational Fluid Dynamics (CFD) simulation is proposed to validate airflow direction, velocity profiles, and thermal comfort indices. The expected outcomes include reduced worker heat stress, improved concentration, safer operations, and enhanced productivity.
The triangular bladeless fan aims to bridge the gap between personal cooling devices and large- scale industrial ventilation systems, offering a multi-directional, safe, and energy-efficient cooling solution. This research contributes to industrial design practices by introducing a user- centric, stable, and technologically advanced alternative to traditional cooling equipment, paving the way for prototype development and real-world performance evaluation.
