What this module does and why you need it A cooler driving module that powers a large 75 mm fan blade to deliver fast, effective airflow for cooling and ventilation in compact assemblies. Ideal when you need targeted, reliable air movement in small devices or prototypes. Key benefits Quick cooling: The large fan diameter and driving design produce efficient airflow to reduce temperature in constrained spaces. Easy to install: Compact dimensions (50 x 26 x 15 mm) and low weight make it simple to fit into tight layouts and retrofit into existing assemblies. Strong, measurable performance: Produces sufficient wind to extinguish a lighter flame at 20 cm, demonstrating dependable blowing power for ventilation and airflow tasks. Important attributes Function: Designed as a cooler driving module for fandriven cooling and airflow applications. Size: Precise compact footprint of 50 x 26 x 15 mm allows integration where space is limited. Fan specification: Uses a large 75 mm diameter fan blade for improved air throughput. Compatibility: Works with steering gear and wheel arrangements and is suitable for use as a propeller or in robotic development projects. Practical applications (specific scenarios) Robot development: Mount on mobile robots to provide directional airflow, active cooling of onboard electronics, or use as a propeller in experimental platforms. Prototype propulsion and small craft: Use as a propeller in prototype RC vehicles or airmoving test rigs where a compact, powerful fan module is required. Cooling and ventilation in compact enclosures: Integrate into electronic housings or assemblies that require quick localized cooling without major redesign. Installation and integration notes Compact, lightweight form factor enables straightforward mounting and fastening in constrained spaces and on small actuators such as steering gear and wheel setups. Designed for developers and hobbyists who need a reliable driving module for airflow, cooling, and propulsion experiments. This cooler driving module combines a large 75 mm fan blade, compact dimensions (50 x 26 x 15 mm), and proven blowing strength to deliver practical, easytointegrate airflow for propellers, robots, and small cooling applications.
