Tools for electronic components cooling, welding cooling, and other small area cooling applications. Features: - Cold air source that is portable and widely used in mechanical drying or cooling processes. - Uses compressed air to lower air temperature and produce a low-temperature airflow. - Clean and easy to install; flexible universal tube delivers cold air to targeted areas. - Designed for reliable cooling in demanding industrial environments; capable of continuous and stable operation. - Built-in control valve allows adjustment of outlet airflow volume and temperature as needed. Color: As shown Material: Plastic + metal Working Principle: Cold air is generated by introducing compressed air into the vortex tube at high speed, creating a rotating gas flow. Within the tube, the outer layer of air heats up while the inner layer cools down. As the flow moves to one end, part of the air reverses along the center, forming a cold air stream with a temperature reduction of 25°C to 45°C below the input air temperature, while hot air is expelled separately at around 110°C, creating an effective cooling source.
