Cooling system for high-power drives in belt conveyors

In mining plants (underground and on the surface), high-power machines are used. Electric motors and the gears driven by them have a specific cooling system as a flow system with an internal heat exchanger. The role of the heat exchanger is to collect the thermal energy generated during the unit operation. The refrigerant with the received thermal energy must be led away from the motor and gear unit, where it will be cooled. In the drives used in underground hard coal mines, water is the cooling medium, supplied through a firefighting pipeline. The water used for cooling is often discharged directly to the floor or to sewers, and further it is transported to the surface. The article presents a solution that uses tanks for cooling liquid with highly efficient air-water coolers in surface and underground applications.
