What are Water-Cooled Brake Systems?

A water-cooled brake disc consists of a central and stationary aluminum cooling plate with an internal chamber that circulates water coolant. Cast iron sectors mounted on opposite sides of the disc plate allow contact from the friction material carried by discs on the shaft to be slowed down. The cooling plate and iron cast sectors are separated by thermally insulative layers such as thin air gaps. The sectors retain the heat generated from braking for a short period, which is then transferred to the water over a longer period at a rate determined by the conductance of the thermally insulative layers. This design efficiently absorbs and dissipates braking heat, mitigating the risk of overheating.

When are Water-Cooled Brakes Necessary?

Traditional air-cooled braking systems may not suffice in heavy machinery due to insufficient airflow for cooling. In such cases, water-cooled brakes provide a more effective cooling solution. Water has a higher density and faster heat transfer rate compared to air, making it suitable for applications where space is limited and optimal cooling is required.
